Remarks from Rector of Universitas Pembangunan

Nasional Veteran Jawa Timur

Assalamualaikum Wr Wb.

On behalf of The Rector of University of

Pembangunan Nasional Veteran Jawa

Timur, I would like to extend my warmest

welcome to all participants, delegates from

all over the world, and keynote speakers to

the IJSCT 2019. Welcome to Surabaya, at

Sheraton Hotel & Tower. Welcome to

Surabaya, one of the biggest city in

Indonesia, and called a heroes city. This city

holds many stories of struggles against

invaders. No wonder that in Surabaya, we

can find many unique architectural buildings and historical heritage.

Welcome also to our University, Belanegara Campus. Our campus was

characterized by specific character building of our student. We develop a

patriotic soul and patriotism in our learning process.

Taking place every year, the theme of this year’s conference is “Industrial

4.0: The Opportunities and Challenges In Elevating Local Resources

Contribute To Develop A Better World”. This theme is intended to

promote the relationship between the manufacturing industry and the local

resources. In the Industry 4.0 era, the ‘real’ and the ‘virtual’ world are to

be connected to what is known as cyber-physical production systems. As

a result, the traditional manufacturing processes are undergoing an

enormous transformation which will change the way companies approach

manufacturing, and it will cause a polarization of the labor force. Industry

4.0 also will have the potency to change the nature of jobs, education and

skill requirement; because it requires the increasing of technical

competencies. The use of rapid technology will contribute to increased

efficiency; and will affect productivity, competitiveness, and employment.

We are very pleased to welcome you in the proceedings book of the IJCST

2019. These proceedings are one of the continuations for the conference.

Based on these papers, hopefully, more collaborations can be initiated or

should be followed up between us.


VIII

I would like to express my gratitude to all of the participants, keynote and

invited speakers as well. Many thanks also go to the reviewers and the

editorial team for their big effort in supporting this proceedings book. Last

but not least, my big appreciation to the steering and organizing

committees, in realizing this proceedings book. Thank you.

Wassalamulaikum wr wb.

Remarks from Rector of Universitas Negeri Makassar

In this modern era, the impact of changes in

science and technology is very significant to

human life. Industrial revolution 4.0 comes as

a new era characterized by computerized digital technology. This era has changed the

order of human life from manual systems to

automated systems.

2018 international Joint Conference Science

ana Technology (IJCST) is an international

level conference organized by a consorsium of

9 university including Universitas Negeri

Surabaya, Universitas Pembangunan Nasional Veteran Jawa Timur,

Politeknik Negeri Bali, Universias Trunojoyo Madura, Universitas Negeri

Makkasar, Universitas Negeri Manado, Politeknik Negeri Jember,

Universitas Negeri Makassar Musamus. This joint conference brings

Together research from various countries who aim to share resources and

innovation in relation to the era of digitalization where this year the focus

in on thr fields of chemical engineering, science and technology,

information systems, electrical engineering, food technology, veterinary

animals, health which is expected to strengthen the relationship between

researchers.

Universitas Negeri Makassar is very proud to be a member of the IJST

2018 consorsium. The hope is that it can foster collaboration between

institutions, especially the increase in the number of scientific publikations

by displaying research results, innovative ideas, and experience in the field

of science and technology.

On behalf of Universitas Negeri Makassar, let me congratulate the

implementation of IJCST 2018. Hopfully this activity can benefit

researchesrs to be able to socialize and interact with other international

seminar participants.

Remarks from Rector of Universitas Negeri Manado

Salam Sejahtera bagi kita sekalian,

Assalamu’alaikum warahmatullahi

wabarakatuuh.,

Om Swastiastu, Namo Buddhaya, salam

kebajikan

First of all, allow me as the Chancellor of

Manado State University to give Praise and

Gratitude to the presence of Almighty God

because of His grace and participation so that the

2019 International Joint Conference on Science

and Technology (Surabaya) can run well.

In the current 4.0 Industrial Revolution era, innovation takes place very

quickly with competition in various fields which are increasingly stringent,

including in the world of Higher Education. To be able to advance and

compete globally, inevitably Higher Education must continue to encourage

and support the development of Education and Learning Activities,

Community Service and Innovative Research for lecturers and students.

The results of the research should not only be stored and deposited in the

Higher Education environment but must be widely disseminated so that it

can be known by all interested parties. Moreover, based on

Permenristekdikti No.20 of 2017, Lecturers with functional positions as

Professor and Head Lecturer must conduct Scientific Publications both

nationally and internationally. I see the 2019 IJCST to be one of the

appropriate venues for universities to disseminate our ideas and research

results, as a form of public accountability, fulfilment of the conditions of

publication obligations, and active participation in improving the quality

of tertiary institutions, because the articles presented at this conference will

be published in the form of CPCI indexed proceedings (Clarivate Analytics

/ Thomson Reuters / Web of Science).

On this occasion, I also want to give high appreciation to the collaboration

of the Higher Education Consortium in the implementation of the 2019

IJCST which has proven to encourage us to support each other, share

information, reference, experience and even technology in conducting

international conference events, so that we can move forward together and

complement each other in increasing the capacity of each university.


XI

Finally, I congratulate the conference, long live Indonesian Education!

Salam Sejahtera, Wabillahi Taufik Wal Hidayah, Wassalamu Alaikum

Warahamatullahi Wabarakatuh.

Remarks from Rector of Politeknik Negeri Jember

Dear all scientists and participants,

It is my great pleasure and honor to welcome

you to the 2nd International Conference on

Science and Technology (ICST) and the 2nd

International Conference on Social Science

(ICSS) hosted by Universitas Trunojoyo in

Madura (UTM), East Java. The conferences are

organized by IJCST (International Joint

Conference on Science and Technology) which

is originally initiated by some state universities

in East Java, Bali, and Sulawesi.

In this year, the IJCST conferences are held on October 17th - 18th at

Sheraton Hotel & Tower, Surabaya, Indonesia. The conferences are

expected to become a scientific forum for scientists, lecturers, researchers,

and policymakers, to meet and to share their knowledge, research findings,

and thoughts on science and technology that will contribute to the

advancement of practices in the educational world. The ICST is specialized

to those who are interested and committed to the development of science

technology which covers Sciences, Informatics Technology, Engineering,

Power and Energy, Environment, Geology, Industrial Engineering,

Mining, and others. While, the ICSS accommodates those who are

specialized their researches on social science such as those of Law,

Education, Cultural and Communication Studies, History, Political

Science, Psychology, Sociology, and Library Sciences.

In the age of Industry 4.0, science and technology have now become one

of the strategic sectors which underpin the development of a society and a

country. By encouraging studies and innovation in these areas, I believe

we can do our best to change difficulties into opportunities and to make a

better life for now and future. This is in line with the theme of these

conferences “Industrial Revolution 4.0: The opportunities and challenges

in elevating local resources contribute to developing a better world”.

Therefore, this is not exaggerating statement to assert that this conference

disserves to gain our attention to make it continued and witnesses the

expected changes in our education, society, nation, and world.

Remarks from Rector of Musamus University

Honorable the Chancellors, the Deans of the

Consortium Members, the keynote speakers,

the authors (lecturers and researchers), the

committees and all participants.

Shalom and best wishes.

Praise be to the Almighty God for blessing

and guiding us into this special moment, the


Technology (IJCST) 2019.

It is such an honor to be and take a part in this consortium, the 2nd IJCST

2019 organized by the University of Trunojoyo Madura. We realize that

this conference is the right place for researchers in the fields of science and

technology, social and humanities to improve the quantity and quality of

their research publications, beside their obligation to carry out the Tri

Dharma of higher education. Each lecturer is required to publish the results

of his/her research in either national/international journals or in national /

international conferences. This is absolutely important for improving

lecturers’ achievement and influencing university ranking.

We realize that to keep existing in publications in either international

journals or conferences is not easy, especially for the new state universities

such as Musamus University. Therefore, it is extremely significant to make

an agreement in consortium to conduct international seminars regularly.

Musamus University is committed to increase the quantity and quality of

lecturer publications to improve university rankings and as a capital for

lecturers to improve academic positions. Therefore, Musamus University

is very proud to be accepted and for the second time taking a part in the

Higher Education consortium at the International Joint Conference on

Science and Technology to increase the number of lecturer publications

and university rankings. Hopefully, the implementation of IJCST 2019 in

Surabaya can run well and offer all members and participants of this

consortium the plentiful benefits.


XVI

We hope this conference will be a great and successful event not only as

an opportunity to share knowledge and experiences but also as a start of

good cooperation and friendship among consortium members.

As closing, we would like to extend gratitude to all delegates for their full

cooperation and contribution in IJCST 2019 and the organizers of the

University of Trunojoyo for opening opportunities and working hard for

the convening and success of this conference.

Finally, allow me on behalf of Musamus University to wish you a fruitful

and pleasant international conference.

Thank you

Prof. Dr. Philipus Betaubun, M.T

Chancellor of Musamus University

Remarks from Rector of Universitas Pembangunan

Nasional Veteran Jakarta

“The measure of intelligence is the ability

to change”(Albert Einstein)

Intelligence (intelligence) is a person's ability

to think logically, communicate, learn, know,

understand, remember, have planned, think

creatively and be able to solve problems.

Learn from the experience and also be able to

adapt to the environment. Intelligence is

synonymous with the tertiary environment,

lecturers who have the task of doing higher

education, education, and research and

community service.

For the performance of the field of research, especially in the Ministry of

Research, Technology and Higher Education currently in the spotlight, Mr.

Jokowi - President of the Republic of Indonesia. On the occasion of

opening the 2018 Plenary Cabinet meeting, Mr. Jokowi once questioned

the benefits of a research fund of Rp. 24.9 Trillion in various

ministries/institutions that have no impact on the resolution of community

problems.

(https://bisnis.tempo.co/read/1077794/jokowi-question-results-riset-with-

budget-Rp-249trillion )

The International Conference on Science and Technology (ICST) with the

theme "Industrial Revolution 4.0: The opportunities and challenges in

elevating local resources contribute to developing a better world" can be

used as a momentum for us to answer the President's turmoil by producing

research that is not only just stop in publication to fulfil the task of research

darma alone but to continue to be research that is able to answer problems

in society, especially in the digital era, the era of technology, the era of the

industrial revolution 4.0.

This conference was held by involving 12 universities, this collaboration

will be a driving force for quality research, and each university has its

advantages in the direction of research which can then be joined by experts

in other universities. In the current competitive era of collaboration,

resource mobilization is a must. Nobody can do something individually at

this time.

UPNVJ hopes that after this conference the lecturers will follow up on

these studies by pioneering, building cooperation with the industrial world

so that the downstream is achieved, then the researchers will communicate

with each other intensely to follow up on this activity by conducting joint

research.

Finally, Congratulations and Success for the International Conference on

Science and Technology (ICCT) and thank you UPNVJ for the opportunity

to participate in this activity.

Coming together is a beginning

Staying together is progress

Working together is a success

Network configuration optimization for wireless local-area

network with three Raspberry Pi access-points under

concurrent communications

Nobuo Funabiki

Okayama University, Japan

[email protected]

Abstract- Nowadays, the wireless local-area network (WLAN) has been deployed

around the world as an inexpensive and flexible access network to the Internet.

Because WLAN does not need a cable to connect a host or a mobile device with

an access-point (AP), it has several advantages over a wired LAN such as low

installation and management costs, easy host relocations, and flexible service

areas. In WLAN, 11 or 13 partially overlapping channels (POCs) are available at

the popular 2.4GHz. Each POC has the 20MHz frequency width, and the

frequency gap between two adjacent channels is only 5MHz. Thus, one POC is

interfered with at least three neighbor channels. Currently, the IEEE 802.11n

protocol is common in WLAN, which adopts the high-speed wireless

communication technologies, including the channel bonding (CB), the multiple-

input-multiple-output (MIMO), and the frame aggregation. Among them, CB

enhances the speed by bonding two channels into one. Thus, when multiple APs

in a network field are concurrently communicating, they are always interfered

with each other. The throughput feature becomes different from the single

communication. To realize a low-cost WLAN, we have studied the use of

Raspberry Pi for the software access-point (AP) in the IEEE 802.11n WLAN.

This device has become popular around the world as a low-cost, small, and

powerful computing one. Since the built-in wireless network interface card (NIC)

fails to support CB, we have configured CB using an external NIC adapter and

investigated the performance. Besides, we have studied the two-step throughput


2

estimation model to estimate the throughput or data transmission speed of a

WLAN link for the single communication. The first step estimates the receiving

signal strength (RSS) at the receiver by using the log-distance path loss model.

The second step calculates the throughput from that RSS using the sigmoid

function. Both functions have several parameters affecting the estimation

accuracy. Thus, their values are optimized by the parameter optimization tool. In

this talk, we introduce our latest studies of the network configuration optimization

and its related topics for the IEEE 802.11n WLAN using three Raspberry Pi APs

with 11 POCs. First, we present throughput measurement results in concurrent

communications of three Raspberry Pi APs with/without using CB. Second, we

extend the throughput estimation model by introducing the reduction factor to

consider interferences among them. Third, we propose the network configuration

optimization algorithm for WLAN with three Raspberry Pi APs using the

extended throughput estimation model. The network configuration signifies the

adoption of CB or non-CB, the channel assignment, and the host associations for

each AP. Finally, we evaluate the algorithm through simulations and testbed

experiments.

The Fundamentals of IOT, Blockchain and AI

Technologies and their Fusion will be Illustrated on

Industry 4.0

Prof. Shuo-Yan Chou,

National Taiwan University of Science and Technology (NTUST)

Internet of Things (IoT) will be making impact to the society not just in an

incremental way but a disruptive way. With the sensing and wireless connection

capability of physical objects and environment, humans are able to reach far

beyond their physical constraint in time and space and becoming an integral part

of the connected world. It is not only transforming the way business is conducted

but also the way we live and perceive. Combining with the advancement of

blockchain and AI, the digital fusion has been quietly pushing the industry

towards the fourth industrial revolution. The three digital technologies

complement to each other, enabling a great number of innovative applications

and services and allowing the impact goes beyond manufacturing industries. The

new World Wide Web (Web 3.0) will have these three technologies contributing

significantly to its core values. In this talk, the fundamentals of IoT, blockchain

and AI technologies and their fusion will be illustrated on Industry 4.0 as well as

applied to address smart city issues.

Abstract - The study of plant disease detection systems development has become

very popular especially after the introduction of precision agriculture and the

widespread use of mobile computing in almost all area including agriculture.

While there exist an abundance of frameworks or models, however, given the

unique nature of pest and disease management influenced by the different types

of cultivation setting such as location, history, soil and the threat’s, research in

this area is still needed. In addition, crop disease and pest detection is a complex

task requiring accumulated knowledge and expertise as well as collecting detailed

information very often manually. Therefore, on the basis of generic expert system

model, this research aims to develop a conceptual model of mobile expert system

for pest and disease management. Drawing from the case study of MyCorn

development project, this study specifically offers a conceptual model of mobile

application which offers a collaborative platform for integrated corn crop disease

and pest diagnosis, treatment, and protection. The findings also offer useful

practical insights for those who are seeking to build similar expert system for

agriculture crops other than corn.

Abstract - ASSAB 618S steel is a type of medium carbon steel that is often used

as a machining tool for the petroleum industry. Based on the observation, it does

not work optimally due to high acidity. As a result, there is corruption in the

machining tool. In this study, an electroplating process will be carried out as a

way to overcome corrosion in machining made of ASSAB 618S steel. The

variables involved independent variables, dependent variables, and control

variables. The independent variable is the temperature of the electrolyte solution

with variations of 55oC to 70oC. The dependent variable is the corrosion rate on

the results of electroplating hard chrome coating. The controlled variable is the

distance of electrodes with variations of 3 and 9 cm. The data obtained showed

that the highest corrosion rate was obtained from the temperature variation of the

electrolyte solution of 55 degrees Celsius and the electrode distance of 9 cm,

while the lowest corrosion rate was obtained at a temperature variation of 70

degrees Celsius electrolyte and 3 cm electrode distance. The data is in accordance

with the theory of corrosion rate that is smaller better. It means that the smaller

the corrosion rate, the better the corrosion resistance. Based on the results of this

study, it can be concluded that the temperature of the electrolyte solution, the

distance of the electrode, and between both interactions give an influence on the

corrosion rate of the electroplating hard chrome coating.

Abstract - Every Muslim individual has an obligation to pray five times a day.

He/ she can do the ritual at a mosque, a prayer room, and some private areas. A

place with a comfortable and an appropriate space would make individual

performing the prayer well. Considering that most individual use a prayer mat

during the ritual, this study aimed to identify an appropriate size of the prayer mat

for Javanese students at the University of Trunojyo Madura (UTM). Two hundred

students (90 males) involved in the study. Seven postures of the prayers motions,

namely: body height in standing posture (BHS), shoulder breadth (SB), foot

length (FL), buttock to the top of the head in a bowing posture (BTHP), tip of

foot finger to the top of the head (TFHP), elbow to elbow distance during

prostrating (EEDP) and the maximum width during tawarruk sitting (the final

sitting) (MWTS), were selected in the measurements phase. The postures

performed by participants should conform to the right posture as exemplified by

the Prophet Muhammad. Results of the current study indicate a significant

difference in the included dimensions between the male and female groups,

except on the maximum width during the tawarruk sitting. This finding implies

to the different size on the prayer mat, especially on its length. It also indicates

the need of different space between the lines during a congregational prayer.

Abstract - Attribute Identification is proposed in this research to help the security

system for identifying the attribute of the pedestrian image.Convolutional Neural

Network is used as the binary classifier in the proposed research because it has

the ability of feature learning; hence handmade feature is not required in this

network. The network architecture consists of the Convolutional, Rectified Linear

Unit, Pooling, and Fully Connected Layer. Three models are proposed for the

attributes identification based on the number of weight layers, they are, ten, eight,

and six.There are seven attributes are identified using seven binary classifiers.

They are male, hat, long hair, backpack, carrying nothing, shorts, and sandals.The

conducted experiments showed that our proposed model achieved higher

accuracy for several attributes compare to the previous model.The highest

accuracy achieved in this research is 86.7% for the male attribute, and the lowest

is 26.7% for footwear sandals.

Abstract - Delays in completing one of production cycle will affect the entire flow

of the next production process. DI is a manufacturing company that manufacture

aircraft. In 2017 there was a delay in manufacturing processes of A380 aircraft

wings, especially in machining parts, which resulted in delays shipping to

assembly parts. This delays affected time delivery to customers. So that,

scheduling plan was needed in this company. This paper proposes comparation

of three scheduling methods, which are Campbell Dudek Smith, Palmer and

Dannenbring with the aim of minimizing makespan. Result of this study describes

that the best method for minimizing makespan is Campbell Dudek Smith method,

with a scheduling sequence starting from job 13-6-5-3-10-4-9-1-7-8-18-11-14-

19-17-2- 12-12-15-16, and the makespan value of 46.03 hours.

Comparing the Time Required for Dead End Filler and

Wall Follower Algorithm in Solving Perfect Mazes

Y F Hendrawan1

[email protected]

Abstract - A maze is a collection of walls and spaces arranged in such a way that

they form a path/paths usually connecting an entry point to a goal. There are

various kinds of maze solving algorithms. These methods are used in practice to

help navigate an autonomous system to find a path within maze to find a target

such as an exit point, special item, or location to the next level. This research

explored two maze solving algorithms: Wall Follower and Dead End Filler.

Experiments were conducted to measure the time needed for each algorithm in

solving 50 perfect mazes of various sizes. The test mazes were generated

dynamically using Recursive Backtracker method. The result showed that Wall

Follower algorithm is faster than Dead End Filler algorithm. The difference is

slightly under twice as fast; for example in solving 800 x 800 cell mazes, the

former required an average time of 98.74 milliseconds while the later needed

171.94 milliseconds.

[email protected]

Abstract - Study on robot navigation has been progressing significantly. However,

research of autonomous navigation is still lacking in environments with changing

layout. For supporting robot navigation system, rotational and translational

motion estimation need to be improved. Low cost sensor such as Kinect can be

used as alternative to laser to percept changing in the vicinity of robot. There is

still problem in developing motion estimation using Kinect. Narrowness in the

sensor field of view limits its ability to track robot motion. This problem emerges

specially in translational motion estimation. This paper aims to develop a simple

approach based on RGB-D data for translational motion estimation of a Kinect

sensor. RGB-D data consist of RGB and Depth images. In previous research,

camera was positioned in the direction of longitudinal translational motion. This

paper differs from previous works in terms of sensor setting that is placed in the

direction of lateral translation movements. Point features are matched between

pairs of RGB frame to get interesting pixels. Depth image provides distance

information for these pixels in synchronization with feature tracking process. Law

of cosines is then applied to these depth pixels to get position translation. Results

show that our approach have decreased RMSE to 0.0382 meter better than

previous works. In the future research, this translational motion estimation system

will be implemented in mobile robot system to support navigation function.

Surabaya

Abstract - The quality of agricultural land is an important factor for corn farmers

in Madura. To overcome this problem, biopesticides can be used in the form of

bacteria that can kill plant pest organisms (OPT). Bacillus thuringiensis is one of

the bacteria that can produce protein crystals that are insect killers (insecticides)

when undergoing a sporulation process. By studying this identification, it is

expected that farmers can analyse the use of pesticides and replace them with bio-

pesticides that are more environmentally friendly. In this study, an image

processing approach was used to identify the presence of biopesticide bacteria.

At the pre-processing stage, the stages of a culture of bacterial colonies were

carried out on Mac Conkey media, followed by repairs to the results of image

morphology. Fuzzy Clustering level set is one of the methods used in the image

segmentation process. The results of form extraction are then used in the training

process to determine the type of bacteria in the sample. This method makes

identification of agricultural land easier, faster and costs less. The result is that in

processing 100 training data and 25 data testing using Bacilli bacteria with 9

bacterial morphological attributes and 2 identification classes the accuracy value

of the Random Forest decision tree was 91%.

University of Trunojoyo Madura, ID

[email protected]

Abstract - One of the causes of injuri is operator work and machine that is not

ergonomic. On SISCO, usage the length of the handle of the punching tool which

is made of iron becomes one of problems in the punching process. The manual

punching process requires great energy and strength. This causes operators

complaints during the production process include hand and arm muscular pains.

One of the ways to minimize pains, injuries, and accidents is using biomechanical

approach. The method used in the biomechanical approach is using

biomechanical modeling Single-segment Static Model. In the study obtained, the

calculations of moment of force at the initial position of palm, forearm and upper

arm generated values of 14.7175 Nm, 29.5236616 Nm and 32.1110157 Nm,

while moment of force at the final position of palm, forearm and upper arm

generated values of 34.2256666 Nm and 37.396405 Nm.The calculations of

moment of force at the initial and final positions indicate that the distance of arm

influence the moment of force; the longer the arm length, the bigger the moment

of force produced.

Abstract - A restaurant menu recommendation system is becoming a necessity

following the trend of eating out at the restaurants. The task of such a system is

to generate a top-Nlist of menus that may be of interest to a customer, in which

the customer previous rating behavior is used as the learning model. In this paper,

we apply the SVD (Singular Vector Decomposition) latent factor model as the

learning technique of the recommendation system. Beforehand, we implement the

mean imputation technique to fill in the missing rating entries so that SVD can

also deal with the new customer that has no rating record in the system.

Evaluation on a real- world restaurant menu recommendation dataset shows that

our recommendation system is able to generate a top-10 list of menu

recommendations to a target customer and that the results of the low-rank

approximation using SVD are comparable with that of the full-rank.

Abstract - In a business organization that uses Information Technology (IT), the

IT Master plan is a guide to building information systems and technologies that

are in line with the organization's goals, vision and mission. This research was

conducted in the HVA Toeloengredjo hospital. HVA hospitals are hospitals

whose their administrative systems has use IT. The status of HVA hospitals has

been accredited so that the application of SIM Hospital has become one of the

hospital business management strategies. For SIM implementation, it must be

supported in the IT master plan in terms of hardware, software, infrastructure,

quality of human resources and operational standards of the procedures

implemented. This study aims to determine the level of IT implementation in the

IT master plan dimension, therefore a survey step is needed. The interview

method or questionnaire paper on the implementation of the survey is considered

to be less effective, because it takes a long time and costs more. In this study an

online survey application was built to support the IT master plan. On the results

of online survey processing analyzed using a Likert scale with a scale range of 1

to 5, it was found that 42 respondents of HVA Hospital stated that 84.30% of IT

master plan conditions were ideal supported by good IT conditions of 73.40%,

resulting in a comparison the two conditions are that 87.07% of the level of IT

implementation in HVA Hospital is very good.

Abstract - The aimof this study is to remove the influence of weather factors in

order to improve the visual effects of the image and provide benefit to post-

processing. Images captured in hazy or foggy weather conditions can be seriously

degraded by scattering of atmospheric particles, which reduces the contrast,

changes the color, and makes the object features difficult to identify by human

vision and by some outdoor computer vision systems. Therefore image dehazing

is an important issue and has been widely researched in the field of computer

vision. Image haze removal based on dark channel prior can perform very well.

But it didn't deal with sky region and brightness objects because dark channel

prior is not established in these regions. To solve the problem and enhance the

contrast, this paper propose to restored the hazy image by adding the contrast

limited adaptive histogram equalization. With the contrast limited adaptive

histogram equalization method, the results of the dark channel prior results can

be contrasted so that the image becomes clearer and more specific. Experimental

results showed that such method is MSE 0.256 is equal to PSNR of 54,043 With

this research, it is expected that a clean image after processing can provide

maximum information to humans.

Abstract - Text in images express a lot of information for image understanding.

Detecting and recognizing text facilitates many important applications. The

characteristics of a text with different shapes and contour patterns require special

computer vision to detect and recognize when compared to other objects in the

image. Text detection is the process of detecting text in an image followed by

surrounding text with a rectangular bounding box. It can be performed by using

image-based or frequency-based techniques. Many applications require text

detection in images ranging from automatic detection of traffic signs that help in

the transportation systemto assist blind people and others in need. The data of this

study were Focused Scene Text with the JPG format. The method used to detect

the text in images was Fast Fourier Transform (FFT). The final results of the study

showed that 95% of the text could be detected in an image by various camera

perspectives and was expected to help develop text recognition applications in an

image.

Abstract - Recently, computer vision research results have supported many

sectors to assist and solve problems. One of branch of the computer vision fields

is biometric system. Many modalities have been implemented to depict the human

characteristics. Face is one of the modalities that has been employed to recognize

the human. A crucial problem of the face recognition is high dimensionality. The

problem would impact on the computational performance, and even it could cause

the process failure. Feature extraction is the solution to reduce the dimensionality.

However, many cases have shown that feature extraction could fail as singularity

problem. In this research, we proposed the improvement of the fisherface

algorithm to solve the singularity problem. We have modified the singularity

covariance matrix so that the matrix can be further handled and processed.The

purpose of the paper is to improve the performance of the fisherface algorithm.

We have verified our proposed algorithm by using the Olivetty Research

Laboratory face image. We applied 7-cross validations to evaluate our proposed

algorithm, the evaluation results achieved more than 92% accuracy.

Abstract - Participation from all relevant stakeholders is important to achieve the

goal of every activity successfully.Nowadays, Information and Computer

Technologies, for example, Biometrics, Internet of Things (IoT) and Big Data are

used to support participation from the relevant stakeholders. Electronic

Participation (e-Participation) already utilized broadly to empower people

participation in politics, business, government, cultural activities. Moreover,

Biometrics has been used broadly for an identification system. Biometrics system

identifies physiological instead of behavioral attributes, such as palm veins, iris

recognition, face recognition, fingerprint, DNA, palm print, hand geometry,

retina, and odor/scent. Therefore, this research would like to collaborate e-

Participation and Biometrics fields from the multidisciplinary perspective.

Furthermore, the literature reviews show that research collaboration between e-

Participation and Biometrics Technologies are still limited. Hence, the objective

of this research was to develop a novel conceptual model of e-Participation using

Biometrics technologies.This paper contributes by developing a novel conceptual

model of biometrics technologies for e-Participation implementation. This

research has some implications. For theory development, this research contributes

to the novel conceptual model in e-Participation, E-Government, Information

Systems, Informatics, Computer Science, Image Processing, and Biometrics

fields. For Practice, the novel model could be utilized for practitioners, policy-

makers, and other relevant stakeholders for e-Participation implementation using

Biometrics Technologies.

Abstract - Content Based Image Retrieval (CBIR) is a process to search for an

image based on the content or features that are inside. Nowadays, many image

retrieval applications have been made to meet the needs, so this application can

provide convenience in terms of the introduction and search for an image. In this

research, we used 10 different objects as image retrieval consists of Bicycle, Cow,

Flower,Frangipani, Grape, Horse, Lovebird, Orange, Strawberry, Tree.These

objects can be expressed in 10 classes. Our aim using these objects is viewed from

the color of every object and the object of a different kind. From that point of

view we built a CBIR system by utilizing the main features of the object (image).

The main feature is the color feature. In this research, the main process is the

extraction of color features with the color histogram and color moments. So in

this research it will produce feature extraction by measuring the similarity in the

library image. This measurement is done by calculating the closest distance using

the euclidean distance method. The data library used in this research is 10 pieces

of data, the test data is 50 pieces with 5 pieces for each of these classes. After

testing using data and methods described above, the results of accuracy are

obtained that the application of the color moments method gets better results than

the color histogram method.

Comparison of Automatic Water Taps Using Ultrasonic

Sensors and PIR Sensors

Vivi Tri Widyaningrum1



[email protected]

Abstract - Water is vital for all living things on the earth, so there must be an

effort to save water. One effort to save on water use is by making automatic water

taps. Automatic water taps which are meant here are water taps on the sink and

also water taps for ablution. The working principle of the two taps is the same,

that is, the water tap will open if there is an object (human) detected in front of

the water tap. In this automatic faucet system the arduino mega 2560

microcontroller is used as data processor obtained from ultrasonic sensors and

Passive Infrared Receiver (PIR) sensors. The two sensors are used

interchangeably and the results are compared to determine the difference in

response time. Based on the tests that have been done, it is found that the time

needed for the ultrasonic sensor to open or close the water tap is faster than the

PIR sensor. When opening the tap the time needed by the two sensors is almost

the same, which is only 4ms difference. Whereas when closing the tap the time

needed for the PIR sensor is much longer, which is more than 4s. This is because

the process of returning the sensor to return to normal is not detecting the presence

of humans or in other words the sensor does not detect infrared rays tend to

require a longer time. As for the ultrasonic sensor because what is detected is the

distance, so the object moves from the front of the tap then the distance detected

will change immediately so that the tap will immediately close again.

[email protected], [email protected]

Abstract - Madura Island is one of the largest peanut producers in Indonesia, but

the production of peanuts produced on average is still relatively low, ranging from

0.7 to 1.5 tons / ha. The low yield of peanuts is caused by several factors, one of

which is unstable environmental conditions and pests that attack plants. Efforts

to increase production can be done by monitoring / checking plants. Monitoring

is usually done directly but it is not effective, people often have other jobs besides

monitoring so they can forget about the plants. Based on this problem a

monitoring system and control of peanut growth in a web-based plant house were

designed. This system will carry out monitoring in the form of real time video

and the detection of temperature and humidity sensors to stabilize the conditions

in the plant house based on conditions of temperature and soil moisture. In

addition to monitoring this system provides 2 control modes namely automatic

control and manual control to control watering solenoids and heating lights. The

results of designing a monitoring and control system obtained data that is real

time video capable of monitoring with speeds of 110 kb / s to 420 kb / s, sending

sensor monitoring data no later than 1 second from the detected temperature

changes, manual controls running according to the command on / off and not

affected by environmental conditions day and night, automatic controls run in

accordance with the conditions set based on readings on sensors of temperature

and soil moisture, ambient temperature affects the level of soil moisture and

operation of the web can be accessed from different laptops but only on 1 network

and web can only be accessed by someone who has an ID.

Abstract - A vehicle is a transportation that is widely used by humans as

transportation for daily activities. Vehicles generally use mechanical brakes to do

braking, these mechanical brakes have a system that requires friction forces to

produce a slowdown in the vehicle. The frictional forces carried out will make

erosion of the mechanical brake pads and the need to periodically replace the

bearings. In this study discussed the design and manufacture of braking systems

using electric brakes to support the performance of mechanical brakes. Electric

brakes that have advantages in the media used compared to mechanical brakes,

namely electric brakes do not require friction media to slow down, but electric

brakes use four aluminum plates as magnetic force media, while coils or windings

with the inner core will produce electromagnetic force as an actuator braking. The

braking system that is carried out will maintain the speed according to the setpoint

value of 5100 rpm. This electromagnetic braking results in a maximum braking

of 500 rpm and takes between 9 and 15 seconds to reach the steady state position.

Abstract - Indonesia has great marine resource potentials due to its geographical

location. Among other resources, anchovy becomes the prior Indonesia's marine

commodities greatly consumed by domestic residents and demanded by many

importers. Unfortunately, the production process of dried anchovy seemingly

encounters several problems, especially in the drying process. Since the drying

process uses sunlight, it comes into problems with a cloudy weather or rain. Less

intensity of sunlight might make the drying process result not perfect dried

anchovy. Moreover, current manual monitoring technique remains ineffective

drying process. Thus, this study aims to design a prototype of automatic anchovy

drying robot using Arduino ATmega 2560 microcontroller to address the

problems. This study considers the uses of Arduino ATmega 2560 as a robot

controller, DC motor as a driving system, and LDR and rain sensors as automatic

modules. LDR sensors are used as a robot roof drive or anchovy drying container

to open automatically when sunlight is detected. In addition, rain sensor serves to

close the robot roof when it detects rains and the robot turns into its initial

position. This robot is further expected to be able to work automatically and

optimally in helping anchovy drying process.

Abstract - Knowing and learning hijaiyah letters is a very important basis in

reading Qur’an from an early age. For some normal people knowing and learning

hijaiyah letters is relatively easy but unlike the children who have special needs

like deaf and hearing impaired children. They can only communicate using sign

language both in the form of hand gesture, body gesture, and facial expression.

From these problems, the author the author is motivated to make a system for

implementing the hijaiyah letters cues for deaf and hearing impaired children

using PCA (Principal Component Analysis) method which was installed on

desktop computer.The process of hand gesture recognition consists of several

steps: camera initialization, preprocessing, feature extraction using PCA to find

eigen value and eigen vector, and hand classification using euclidean distance.

The output of hand gesture recognition is hijaiyah letters identification from alif

to ya’ in the form of text and sounds.

Abstract - Quality is one of the important factors that makes a company survive

in the industrial world. PT. X maintains the quality of its products by conducting

quality tests on all products that will be sent to consumers. Although the quality

test has been carried out on products, there are still consumers who receive

defective products. To reduce product defects, a risk management approach is

carried out. Risk management is a method in which organizations can identify

problems with a comprehensive and systematic management approach. The

method used in this study is Seven tools and House of Risk (HOR). Phase 1 of

the House of Risk (HOR) method used to search for risk agents must be

prioritized by looking at the valueof Aggregate Risk Potential (ARP).

Furthermore, the ARP value is used as input for House Of Risk phase 2 to find

mitigation strategies that can be applied in the company. Based on the

identification of risk events there are 24 risk events in the production process and

there are 21 causes of risk (risk agents). The causes of risk that must be

prioritizedare 10 causes of risk with the highest ARP value of 2699, ie the

operator ignores the SOP. So that the causes of risk must be prioritized for

improvement.

Abstract - Soft segmentation is used for extracting foreground and background on

image or video sequence. In this paper we proposed a new method soft extraction

from an image or video using image registration based on nonlocal matting. One

of disadvantages in nonlocal matting is needed to obtain constraint manually.

Constraint is used to identify foreground and background area on separate image

region. Based on registration method, we try to reduce a cost to determine it. First,

a constraint is obtained with identify key points detection and descriptor between

image source and template. Image template was provided before extracting. Then

soft segmentation, nonlocal matting method, is used to extract region. In our

experiment result, we show that our proposed framework has significant

performance improvement over state-of-the-art.

Abstract - Stateuniversities are the hope of most students who want to continue

their education to a higher level after high school / equivalent. To enter college,

students must take the selection test held by the desired university. For state

universities the selection test is held simultaneously and simultaneously called

the SBMPTN (Joint Selection to Enter State Universities). This selection is

carried out nationally and the participants are all students who want to get the

opportunity to enter a state university. To get results that are as expected, the

participants must make some preparations including the Try Out. By doing

SBMPTN Try Out, it is expected that participants can compete with other

participants and can graduate according to their choice. Try Out can be done at

the place of tutoring that holds it or by buying a book containing Try Out

questions. Along with the development of Smartphone technology, a prediction

system will be created from the results of an Android-based SBMPTN Try Out

that will provide information on study programs and universities that are likely to

receive. SBMPTN participant candidates can practice questions anywhere and

is generally used for the building frame. An electric arc welding is one of the

welding methods of joining the metal by means of an electric arc flame which is

directed to the metal surface to be joined. The research conducted using factorial

Completely Randomized Design (CRD) in the Design Of Experimental method.

The aim of this observation is to investigate the influence of independent

variables on the dependent variable, whether the types of cooling (X1), types of

groove welding (X2) and welding currents (X3) affect to distortion of welding

(Y) on the st 37 steel joints. The significant data are indicated by the normal plot

distribution in which the significant factors (A, C, AC, BC, and ABC) influenced

the response. The A factor is the type of cooling, C factor is welding currents, AC

factor is a combination of cooling types and welding currents, BC factor is

combination factor between types of groove welding and welding currents, and

ABC factor is combination factor of cooling types, groove welding types and

welding currents. Based on the regression model reached the value of RSquare is

75.99%, which means the A, C, AC, BC, and ABC factor represent the influence

on the distortion of welding at that value. While the rest of 24.01% is described

Abstract - The manually scheduling system is considered less effective and

efficient because it requires a long time. Problems will become more complex if

the number of components or data used is increasing. The schedule is expected

not only not to experience clashes, but also to adjust to some limitations that must

be met. Genetic Algorithm is one of the heuristic search algorithms that are very

well used in solving optimization problems. The problem of scheduling genetic

algorithms is considered to have good performance in finding the optimal

solution. Genetic Algorithms implement an evolutionary process by randomly

producing chromosomes from each population These chromosomes produce a

solution to the problem raised, namely scheduling subjects. The conclusion of this

study is to be able to arrange the schedule of subjects efficiently, by overcoming

obstacles such as clashing schedules without eliminating the constraints that must

be met.

Nopember , Indonesia

[email protected]

Abstract - Fluctuations in crude oil prices can affect a country's economic

policies. The movement of crude oil prices tends to be nonlinear and non-

stationary. One forecasting method that is intended to accommodate these traits

is forecasting that integrates empirical mode decomposition (EEMD) ensemble

methods based on artificial neural networks and genetic algorithms. In the EEMD

method, a white noise signal is added to compensate for the mixture mode that

can be formed. Each IMF and residue generated in the decomposition process are

used as input to a feedforward neural network (FNN) artificial neural network to

obtain forecasting models from each IMF and residue. The genetic algorithm is

integrated with the FNN to avoid overfitting, the formation of local optima

solutions, and the sensitivity of the selection of FNN parameters. The data in this

study uses West Texas Intermediate (WTI) and Brent oil prices. The results of the

performance comparison trials for several combination forecasting methods can

be concluded that the forecasting results that integrate the EEMD method with

JST-GA provide better results compared to the forecasting method that integrates

EMD with ANN and EEMD with ANN. The forecasting method developed in

this study resulted in forecasting with RMSE / Dstat values of 0.0257 / 61.5936%

and 0.0270 / 72.0930% respectively for daily and monthly data from WTI oil

types; and the RMSE / Dstat value of 0.0229 / 58.8128% and 0.0300 / 81.5789%

respectively for daily and monthly data from the type of Brent oil.

Abstract - Web crawlers are programs that are used by search engines to collect

necessary information from the internet automatically according to the rules set

by the user. With so much information about sports news on the internet, it takes

web crawlers with incredible speed in the process of crawling. There are several

previous studies that discussed the process of extracting information in a web

document that needs to be considered both in terms of both aspects, including in

terms of the structure of the web page and the length of time needed. Therefore,

in this research the web crawler application was developed by applying a multi-

thread approach. This multi-thread approach to research is used to produce web

crawlers that are faster in the process of crawling sports news by involving news

sources more than one address at a time. In addition to the multi-thread approach,

adjusting the structure of the website pages is also done to ensure the information

to be extracted by web crawling. From the results of the multi-thread

implementation test on the crawling process, this study has been able to increase

speed compared to the single-thread method of 122.95 seconds. But the results of

web update detection, have resulted in a speed that decreased by 6.27 seconds in

the crawling process with unequal data and the speed on the crawling process has

also decreased by 24.76 seconds on server 1 and by 23.92 seconds on server 2.

Abstract - Text File Services is still an option for sending a message, the visible

difference between Text File Services and other services besides the file size of

sending messages is the security level. In Instant Messenger there are features to

secure conversations with various Cryptograph methods, while Text File Services

does not have that feature. Therefore made Text File Services with additional

features Cryptograph. Cryptograph method used is the RSA algorithm. The RSA

algorithm makes the plaintext increase in the number of characters, so the

Compression feature needs to be added to suppress the increase in the number of

characters. Shannon Fano is a Compression symbol wise algorithm where each

character that is compressed is converted into a new binary code. This

compression is intended to reduce the number of Encryption result characters.

The results of this study obtained information that the RSA and Shannon Fano

methods can be implemented in the text file service, with the longer key being

used the longer the process of decryption of messages with the average value of

the avalanche effect ciphertext and the result of Compression is relatively the

same. The key length used for the possibility of Brute Force is positively

correlated with an average Test Compression Ratio of 1.41 and space-saving of

29.37%.

Abstract - The paper is very important in designing of antenna applied for

Unmanned Aircraft System (UAS) currently uses frequency spectrum allocation

in the 902-928 MHz band for telemetry communication and at 2.4 GHz for radio

control communication, both are irrelevant because they have the potential to be

interfered with by GSM and WiFi communication. Therefore, the payload will be

placed on one of the mobile service frequency allocations according to the

regulation of TASFRI 2014, which is 3370 - 3400 MHz. So, we need antenna

design that can work at that frequency. Because this antenna will be placed on a

moving payload then needs antenna design that has minimal dimensions and

omnidirectional radiation patterns is needed. This paper results that the microstrip

patch omnidirectional antenna can be applied for UAS and can be optimized by

stripline method.

Abstract - Stock market prediction is both attracting and challenging. The

successful of stock price prediction will give financial benefit, therefore, it has

attracted many researchers and practitioners since long time ago. One of stock

prediction performance measurement is the accuracy. There are many methods

for measuring the accuracy, ranging from simple to sophisticated mathematical

formulation. This article describes some of those methods. MAPE is the most

popular accuracy measure for forecasting since it is intuitive, easy to be

interpreted and can be applied to measure the forecasting accuracy for both

individual item and across item groups. However, the MAPE has shortcomings.

First, the value of MAPE will be undefined if one or more of the actual data are

zero. Second, MAPE is very sensitive to outlier data. Third, equal errors above

the actual value result in a greater percentage error than those below the actual

value. Finally, using the MAPE for forecast methods comparison will lead to a

systematically under-forecast result. Even with its shortcomings, MAPE is

preferred for the forecasting accuracy method due to its applicability,

interpretability and reliability. Thus, it is better to look for ways of correcting the

drawbacks of MAPE rather than searching for alternative measures which are less

desirable than MAPE. This paper proposes a modified MAPE using moving

average of the actual data (MAPEMA) to reduce the drawbacks of MAPE. The

result shows that the use of MAPEMA can reduce the problems of using MAPE.

Abstract - Human body naturally contains complex electrical signals ranging from

the mechanism of the brain, heart, and muscles. Electromyography (EMG) is the

development of biomedical engineering devices used to record electrical signal

activity produced by muscles. The signal produced by the muscle has a very small

amplitude, therefore, an amplifier circuit is required to read the signal using

microcontroller. In this study, EMG signal amplification was carried out

periodically to reduce errors that might occur if only charged to one signal

amplifier. Signal reading was performed by conducting 5 different basic hand

movements. Muscle signal activity during relaxed conditions had an amplitude of

0.05 V. Moreover, it conveyed an amplitude of 0.27 V up to 2.62 V with a signal

gain of 10.350 when the muscle did different movements. The K-NN algorithm

was used to classify EMG signals and determined the hand motion output used as

a basic electronic control system. Results showed success rate of 88%. Failures

when carrying out basic electronic control was due to the signal classification

processes that had not met the parameters and the signal amplitude that was

almost similar to another signal.

Trunojoyo Madura, Bangkalan Madura, Indonesia 2Informatics Engineering, Faculty of Engineering University of

Trunojoyo Madura, Bangkalan Madura, Indonesia

Abstract - Diversity is the main advantage of MIMO (Multi Input Multi Ouput)

radar that improves radar capabilities to identify target parameters, including the

maximum number of targets that can be detected, the target angle, range, etc.

While the weakness of MIMO radar is the absence of coherent gain, it is the main

advantage of the phased-array radar. Combining advantages of both multi-

antenna structures, Phased-MIMO radar has been previously proposed. On

phased-MIMO radar, the antenna is arranged into sub-arrays, each of which is

composed of several antennas with same phase, thereby producing coherent gain.

Diversity is produced by the use of multiple sub-arrays which allows overlapping

of the antennas and uses orthogonal waveforms on different sub-arrays. This

paper reports on the phased-MIMO radar capability to identify target parameters,

namely, the maximum number of targets that can be detected by radar and the

target angle that can be detected by radar.

Abstract - In production process, quality is directly affected by the degradation of

the production machine. Information of products quality may be used as feedback

to determine the maintenance policy. As far as is known, research on integration

of quality and maintenance widely used quality control with 100% inspection.

Many literatures mentioned that sampling inspection is cheaper and easier to be

performed than 100% inspection. With the same level of protection, the variable

acceptance sampling requires fewer samples and provide more information about

the manufacturing process than the attribute data. This paper attempt to integrate

variable acceptance sampling and maintenance policy. The variable acceptance

sampling model developed based on exact sampling distribution approach under

Cpk capability index. If the lot is rejected, 100% inspection will be performed

and Cpk will be estimated. The estimated Cpk resulted minimum cost rate will be

consider as the treshold for conducting PM.

Abstract - This paper presents the performance analysis of different cogeneration

system based on proton conduction SOFC (pSOFC) as main core system in the

intermediate temperature. The cogeneration system such as heat recycle steam

generator (HRSG) and micro gas turbine (MGT) also compared. The new design

to remove heat from stack also proposed to enhance the overall system efficiency.

The results show the pSOFC cogeneration combined with HRSG has higher

system and overall efficiency than combined with MGT. However, additional

power output is produce when combined with MGT. So the option must be

correctly chosen and depend on the customer demands. Finally, with new system

design of cogeneration system, it is possible to achieve an overall efficiency

greater than 81% and 80% when pSOFC combined with HRSG and MGT,

respectively in the intermediate temperature.

Abstract - The higher Internet use also affects the level of information security in

the digital world. Nowadays, many users send private messages or even secret

messages through the Internet. This has an impact on the increasing number of

illegal people who try to see and even change the information for personal gain.

There is a solution to this problem by inserting a secret message in a file such as

images, audio, or video. To increase the level of security, secret messages are

encrypted first using cryptographic techniques. In this paper we propose a method

for developing key generation in audio steganography techniques using the AES

(Advanced Encryption Standard) algorithm. We use additional parameters to

create the AES key, i.e. the user's identity. The user's identity is entered into the

key table which is then randomly selected by the system when the user wants to

get the key. There is a combination process and hash function to add complexity

to the key. The performance of the proposed method is tested based on computing

time and audio signal strength. The test results show that the message inserted in

the audio file does not affect the file size, but rather affects the audio signal

strength. Audio signals that experience additional data are at frequencies of 15 to

20 kHz and for other frequencies only experience additional noise.

Abstract - Partial discharge is a partial electrical discharge event in isolation that

is not directly connected between the two conductors, which discharges can occur

either near or not on the conductor. An Archimedean spiral antenna is designed

to detect partial discharges in high voltage equipment. Electromagnetic waves

generated by partial discharge will be detected by the antenna which has a

frequency range of 300 MHz - 3 GHz. The next measurement of partial discharge

uses an RC detector. The purpose of this study was to determine the performance

of Archimedean spiral antennas which were then compared to RC detectors.

Based on the results of tests carried out as many as 50 times, both the spiral

arsenic antenna or the RC detector showed good results. Antennas get slightly

lower yields, due to the reduction in the flow of electromagnetic waves on the

metal walls of high voltage equipment. Whereas RC detector is better by

displaying more sensitive results.

Abstract - Hospitals are an important part of the health system. This agency

consists of several services. One type of main service that is quite complex and

needs to be considered is inpatient installation. The hospital should make a

structural and functional utilization effort by increasing the utilization of service

space related to the number of available beds. To measure utilization of facilities

in inpatient services, an indicator of inpatient services is needed to measure it.

These indicators include BOR (Bed Ocupanccy Rate), which is the percentage of

beds filled, LOS (Length of Stay), namely the average length of stay, TOI (Turn

Over Interval), which is the average free time of bed, BTO (Bed Turn Over),

namely bed productivity. From the values produced, later it can be used as

material for determining service facility policies in the future. The purpose of this

study is to create a model with a system dynamic so that it has an ideal indicator

value. The scenario in this research is to increase utilization of bed use, the first

strategy of this scenario is to increase the number of patient visits, because based

on reference data the patient's visit is too low. This is evidenced by the value of

the BOR which is less than the ideal value. The second effort is to maximize

patient care. The results of the scenario show that in 2019 to 2030 the average

score of BOR was 79%, LOS 3 Days, TOI 1 Day, and BTO 41 Times.

Abstract - The quality of the components of the machining process is determined

by the value of surface roughness and dimensional precision. This study uses the

Central Composite Design experimental method on the Response Surface

Method. To determine the variation of experiments, three factors and three levels

were used, the specimens used were mild steel with a total of 20 experimental

variations in the EDM (Electrical Discharge Machining) machining process.

Then the surface roughness and dimensional precision are tested. Optimization

is done by the method of non-linear programming, where the first response is

surface roughness and the second response is the precision of the dimensions of

the length of the machining process. The results of the analysis show that the

strong current influences the surface roughness and dimensional precision. While

on time and off time do not really affect the surface roughness or precision

dimensions. Optimization with non-linear programming techniques produces a

minimum surface roughness of 3.805880 (µm) and dimensional precision of the

maximum machining time is 175.2290 (minutes) with a current adjustment of 3

(Amperes), on-time 100 (µs), and off-time 20 (µs).

Abstract— This study discusses the method of measuring and detecting Partial

Discharge (PD) in high voltage electrical equipment that has the characteristics

of being veiled with metal. This research uses the UHF (Ultra High Frequency)

method based on IEC 60270 and RC Detector to detect and measure PD. This

method uses electromagnetic wave energy emitted by PD sources from the metal

box. Use this method to get detection and measure without having to activate the

test object. Then the sensors used in testing in this study are rectangular spiral

antennas and RC detectors. In addition, various stresses will be tested. The

measurement results then compare when evaluating the PD between the

Rectangular Spiral antenna and the RC Detector to determine the sensitivity level

of the rectangular spiral antenna. The test results show the measurement of partial

release of rectangular spiral antenna is greater than outside the metal box and

measurement using RC Detector is more sensitive than using a rectangular spiral

antenna sensor.

Abstract. This study aims to develop a conceptual model of question answering

system in Bahasa using Semantic web technology. A trigger was built to

periodically collect data scattered on the internet in a data center to shorten the

query process on data without reducing the data completeness. The test case

domain was automotive. This study used four types of ontologies: main ontology,

ontologies from manufacturers, dealers, and rentals. This research has some

novelties, such as solving the weakness of distributed and centralized data and

combining the advantages of both by storing distributed data into a pool

(centralized data) periodically, then querying the pool. Furthermore, it makes

contribution by providing a conceptual model of Indonesian question answering

system, particularly in automotive domain. This has some implications, such as

extend the body of knowledge of computer science, especially semantic web and

ontology fields.

Abstract. All Water is the most important source in the human body, healthy

water can help the metabolic processes in the body perfectly. Water used by

humans must be in accordance with those set by the government (Permenkes RI

number 492 of 2010, regarding the requirements and supervision of water

quality). Clean water according to regulations issued by the government through

the Indonesian Ministry of Health is having a PH value of 6.5 - 8.5, TDS (Total

Dissolved Solid) a maximum of 500 mg / L, and a maximum turbidity level is 5

NTU (Nephelometric Turbidity Unit). In the process of managing dirty water

into clean water, it must be done carefully so that the germs in the water are

completely gone and the people who use them are free from all diseases. From

the problems above, a clean water management system has been created. This

system can read the value of water suitable for use or not. Water condition

readings using PH sensor, TDS (Total Dissolved solid) sensor and turbidity

sensor (TSD 10). Data values from the sensor (input) are processed using fuzzy

method as a logic to start the pump if the water value does not match the set point

specified and display the sensor value on the LCD (Liquid Cristal Display). The

results of the whole system were obtained an average error for the sr-HC04

sensor 1%, turbidity 2.12%, the TDS sensor 2.40% and the pH sensor 0.48%.

Abstract. Madurese language is one of the regional languages in Indonesia. This

laguage used by the Madurese people. Preservation of Madurese language now is

minimal. Many migrants come from outside Madura, so communication between

the surrounding communities in the Madura region often uses the national

language, Indonesian. The use of Madurese as a language of communication

began to decrease. This research is an effort to preserve Madurese language by

utilizing the translator system technology. Madurese language is a regional

language that is difficult to learn, because there are many differences found

between writing and pronunciation. To overcome this problem this reasearch

develop text to speech module in the Indonesian-Madurase language translation

system. There are 3 versions of Madurese language level: Enja’-iyyeh, engghi-

enten, and enggi-bunten. The conversion of text into sound is used with the help

of syllable recording data created by the author. The process of chopping words

into syllables is done using the two-level Finite State Automata (FSA) method.

The output of the first level FSA becomes input for the second level. The

application of FSA in Text to Speech applications is effectively used with

accuracy value of 90%. The resulting sound output is in accordance with the

results of syllables, but the pronunciation of some translated sentences does not

have the correct intonation. The accuracy results of the intonation pattern in

pronunciation of the system is 85%.

Abstract. In order to develop the steering control for collision avoidance

behaviour, robot must be able to determine its heading orientation with respect to

environment. Orientation can be measured by dedicated sensors or through visual

features perception. In vision-based orientation estimation problem, most of

approaches are making use of a matching process between pair of frames. This

paper proposes a method of estimating robot's heading orientation by using only

a single-frame of fish-eye image. CIE-LAB colour space is applied to handle

colour and illumination intensity change. Straight line segments are extracted

from thresholded CIE-LAB image take advantage of Progressive Probabilistic

Hough Transform. Angle of the corresponding line segment is measured using

combination of Law of Cosines and quadrant principle. Heading orientation in

yaw angle is estimated by implementing voting mechanism based on region

grouping and length of perpendicular line. Some experiments are made in robot

soccer field environment to compare orientation estimation system against IMU's

measurement. Discussion about the performance and limitation of the system are

included in this paper

Abstract - Smartphones are not only based on main functions such as calling and

sending SMS, but the complete features and design are the basis for consumers

to buy a smartphone. A consumer will be selective in choosing the type and brand,

but does not rule out the possibility that consumers will switch to other brands.

Companies need to know the desires and things that consumers need in choosing

brands and types of smartphones. Based on the problems that occur, this research

was conducted. The research data is sourced from offline questionnaires that are

distributed to consumers who have made a move to a smartphone brand. There

were 107 questionnaires collected and 105 questionnaires which stated that the

filling method was correct. The collected data will be tested for validity and

reliability to determine the extent to which the data is considered valid. To solve

this problem, data mining methods are used that can determine the percentage of

users who move. For smartphone brands that experience a decline in users, a

marketing strategy will be created using SWOT analysis. The results of this study

turned out that Oppo and Samsung smartphone users had decreased. The

marketing strategy for Samsung smartphones is by giving discounts or giving

gifts for large party purchases. Then for the Oppo smartphone marketing strategy

is to reduce promotional costs and invest more into the RnD so that the product

Abstract - At present, the adsorbents generally use bentonite and activated carbon,

but the availability of bentonite is less so that other alternatives are needed for

substitution of bentonite as an adsorbent. One of the materials that have the

potential as an adsorbent is the ceramic industry waste (ceramic clay). Ceramics

clay containing feldspar which before being activated using sulfuric acid has a

ratio of concentration between silica and alumina (silica/alumina) of 3.6, so a

process is needed to increase the ratio of silica and alumina. One such process is

by activating ceramic clay using sulfuric acid. The characterization and

adsorption performance of adsorbent from ceramic clay were studied with various

acid concentration. Ceramic clay powder was activated with sulfuric acid. The

adsorbent particles were characterized by IR Spectra, X-Ray Diffraction, X-Ray

Fluorescence, and BET. Various concentrations of sulfuric acid solutions for

activation have a significant effect on the characteristics and performance

adsorbent. This is indicated by XRD analysis where the characteristics of the

adsorbent have feldspar (Ca-KAl2SiO3) content with the ratio between silica and

alumina increasing around 4.3-4.8 with an increase in sulfuric acid concentration

from 10-30% and adsorbents in the form of mesoporous crystalline structure. The

characteristics of adsorbent with IR Spectra analysis showed that the presence of

silicate alumina groups, so the products have the potential as a bleaching agent.

The best surface area is produced at a concentration of 15 % sulfuric acid solution

with one hour activation time which is equal to 117.44 m2/g.

Abstract - Paper and pulp industry factory is a factory that contributes to national

economic development because paper needs per year can reach 100 million tons..

But not only the positive impact is given, the negative impact is present because

it produces considerable waste. The paper industry's liquid waste is one of the

many wastes containing a lot of metal, for example hexavalent Pb and Cr heavy

metals. It is necessary to reduce according to government standards in order to

reduce negative impacts on the environment. One way to reduce Pb and Cr levels

is ion exchange using cation resin 500 ml paper liquid waste mixed with cation

resin at a volume and weight ratio of 10: 0.0017; 10: 0,0034; 10: 0,0068; 10:

0,0136; and 10: 0.0272. Mixing is done with a 190 rpm stirrer motor and the

variation of time used is 10, 20, 30, 40, and 50 minutes. The best treatment at a

ratio of 10: 0.0272 with a time of 20 minutes. The results obtained by Pb and Cr

decreased by 94% from the initial level.

Abstract - Red Mussels is a food ingredient that is quite popular in East Java.

However, the content of heavy metal (Pb) red mussels is quite high above the

threshold that is permitted for human consumption, which is below 1.5 ppm.

Therefore, the presence of high Pb levels must be reduction according to the

specified threshold. The research was conducted in two steps. The first step, Red

mussel’s extraction using Tamarind solution. Tamarind contains organic acids,

one of which is citric acid which acts as a metal binding agent so as to reduce the

metal content. The second stage of extracting red mussels uses pure citric acid,

then the results are compared. The optimum results obtained at the time of

extraction and concentration using tamarind was 60 minutes and 25%, the

effectiveness of citric acid in tamarind was 98.89% (initial Pb 17.19 ppm to 0.25

ppm) while pure citric acid was 99.97 % (Initial Pb 17,199 ppm to 0,004 ppm).

Abstract - A company needs to improve its performance, especially in terms of

quality, in an effort to assure its survival in the business competition with other

companies. Therefore, the company needs to measure its performance so that it

can find out its current position in the competition and how to improve said

position and achieve its goals. Nowadays, many companies try to improve

themselves by putting more emphasis on product quality, which is an external

kind of quality, instead of on the internal quality of the company. This strategy

will not yield the best result in the long run because the internal quality affect the

quality of the resulting products. One of management systems that put emphasis

on the internal quality and consumer satisfaction is Total Quality Management,

which involves all members of the organization. One approach to the aspects

included in Total Quality Management is to use the Deming Prize, which reviews

the internal quality based on several categories. Based on the results and data

analysis, it can be seen that the score for organizational variables is 3.41;

standardization of 3.00; control of 2.81; analysis of 2.59; and influence of 3.30.

However, there are several categories in the variable that are lower than the terget

score, among others, job analysis, organizational goals, work tools, measurement,

employee input, and rewards.

Abstract - Calcium phosphate compounds are one of the biomaterials that are

widely used for bone reconstruction because they are biocompatible and have a

chemical composition that is close to the inorganic components present in the

bone. Two types of calcium phosphate that are widely applied to the bone

reconstruction process are hydroxyapatite (Ca10 (PO4) 6 (OH) 2) and β-

Tricalcium Phosphate (Ca3 (PO4) 2). This research develops the manufacture of

β-Tricalcium Phosphate by reacting calcium compounds derived from chicken

eggshells and phosphate sources derived from dinatrium phosphate (Na2HPO4)

using precipitation method which is carried out with variations in sintering

temperature 600 to 1000 °C and sintering time of 1 to 5 h. The results of X-Ray

fluorescence (XRF) analysis showed that the Ca / P ratio obtained was 1.74, at

the sintering temperature of 1000 °C and the sintering time for 5 h. These results

have approached a standard where the ratio of Ca / P on Tricalcium Phosphate is

1.5. While based on the results of X-Ray Diffraction (XRD) analysis that in the

sample formed two types of Calcium Phosphate namely β-Tricalcium Phosphate

and Hydroxyapatite so that it can be said that the product produced is Biphase

Calcium Phosphate. The high percentage of β-Tricalcium Phosphate is 81.9%

with the 3 highest peaks, namely at the angle 2θ of 27.83 ; 31.03 ; 34.42 is

obtained at the sintering temperature of 1000 °C and at the sintering time is 5 h.

Abstract - In foreign language teaching and learning process, comparing the two

languages between the source language and target language being learnt can not

be avoided. According to Carl James, (1980:3) [2], Contrastive Analysis is a

linguistic enterprise aimed at producing inverted two-valued typologies, and

founded on the assumption that languages can be compared. Meanwhile (Baker,

1998:48) [1] said that contrastive analysis might also provide some explanations

of difficulties encountered by a translator in translation. In line with these two

statements, it could be assumed that contrastive analysis is closely related to

translation study due to the fact that in translation activity, a translator has to

compare the two languages, source language and target language. This study aims

at describing the relationship between contrastive analysis and translation study.

Based on the study analysis, contrastive analysis could be classified into 2 (two)

main categories, they are micro linguistic contrastive and macro linguistic

contrastive. The first contrastive referred to the language study which is analyzed

in accordance with the rule and structure of the language itself. Meanwhile the

second one is concerned with the relationship between the language and some

other related factors, such as in analyzing the text or discourse. A study on

contrastive analysis is also required in language teaching, evaluation and research

and translation as well. Furthermore, the relationship between contrastive

analysis and translation study was bidirectional. On the other hand, the translation

of specific pieces of text might provide the data for contrastive analysis.

Therefore, a translator would not find if difficult to do translating a text if the

source text being translated had similarities of its linguistic aspects with those of

the target one.

Abstract - Water is the source of human life. Therefore it is necessary to make

optimum use of it to preserve existing water sources. Raw water demand is

influenced by high population growth. The need for raw water in Nunukan

Regency is increasing from year to year. Raw water needs in Nunukan Regency

are met by utilizing water sources from rivers, wells and rainwater. The available

water sources is limited, while the population of Nunukan Regency continues to

grow. Therefore, to meet the needs of raw water in Nunukan Regency, a reservoir

is needed in the area. One of the elements that must be analyzed in the reservoir

design is the hydrological potential that exists including the inflow that fills the

reservoir, storage capacity, and flood discharge plans. The analysis results

obtained that the volume of water that can fill the reservoir is 0.235 x 106 m3,

while storage capacity is 0.013 x 106 m3. Flood discharge plan with a 100-year

return period of 4.701 m3/second.

Abstract - Pollution of Surabaya River from year to year is increasing, the

increase in pollution is the main problem of Surabaya River which is caused by

the entry of most of the liquid waste from industrial, agricultural, and domestic

activities. Continuous pollution can reduce water quality for rivers and creeks.

One solution that can be applied to reduce the level of pollution is by calculating

the capacity of pollution loads. This research was conducted to find out the quality

of Kali Surabaya and tributaries of Surabaya River and the calculation of

pollution load capacity with the QUAL2KW model. The study analysed the

parameters of DO, BOD, COD, and phosphate. From the results of the study, the

water quality values for Surabaya river and its branch were above the Class I

quality standard Government Regulation Number 82 of 2010 and from the

calculation results obtained the maximum capacity values BOD load were 23-

Abstract - The presidential election campaign in Indonesia which was held in

2019 attracted the interest of the Indonesian people. People expressing their

emotion through social media, one of which is Twitter. Supervised learning is

used to classify user’s emotion of that issues. The goal of this research is

extracting the emotional content in tweets. The interest is in whether the text is

an expression of Twitter users' about the presidential candidates and whether this

online forum represents the election results. For this purpose, text mining

techniques are performed and we will compare Naive Bayes Classifier and SVM

in classification process. The result showed that Naive Bayes Classifier and SVM

have good performance for classifiying text and each of classifier have not

outperform the others. The result also showed that stemming step in text pre-

processing do not give any significant result in model accuracy, because twitter

Abstract - Student grouping, particularly in high school, is a necessary process to

divide and classify students into classes based on their abilities and interests. Each

school may have different approaches to decide the grouping, but most schools

use academic grades. The activity occurs every new academic year and schools

with plenty of new students registered may feel a bit overwhelmed with this

grouping assignment. A decision support system which can automatically

perform grouping on a list of students may be able to help the school’s staffs with

this repetitive task. A self-organizing map (SOM) is an example of unsupervised

learning algorithm using an artificial neural network structure to produce a low

dimensional representation from a given input. However, SOM is also known as

one of clustering techniques, since dimensionality reduction may also be seen as

reducing (or clustering) input data to lower dimensions (or clusters). This research

aims to group new enrolled students to a high school based on their academic

grades using a SOM learning algorithm. The grades came from their rapport

books and national examination results from their previous study. The resulting

groups are three distinct clusters which represents Life Sciences, Social Sciences,

and Linguistics study areas.

Abstract - Now the use of information technology has changed citizen’s styles

and lifestyle. Public services that are practical, very fast and automated is the need

for majority of Indonesian society. Coupled with various requests for public

services needed by the community with a variety of specific case studies. This

certainly has implications for the government in presenting services that suitable

with the various needs of the citizen. On the other hand, in increasing the

effectiveness and efficiency of public services, the government has shifted its

business processes by increasing the adoption of e-government. However, the fact

is the IT investments that can reach tens or hundreds millions rupiah every year

can be said to be almost non-existent by governments where most of the

operational processes are carried out electronically. To overcome this problem,

the government should not simply shift the business process with IT adoption on

a large scale. The government needs to adopt a model of organizational agility to

support government IT agility. In anticipating this, several previous studies have

contributed to developing an organizational agility model with IT support.

However, the model developed is still not enough to achieve organizational

agility. Therefore, in this study will synthesize some previous theories relating to

organizational agility using IT support. The result of this study are an analysis of

the synthesis of the agility process models of government organizations with IT

support.

Abstract - Nowadays, progressive parking systems still have disadvantages. It

only serves to notify total parking rates to motorized vehicle users when they are

still in the parking area. Besides, the payment uses cash. Meanwhile, some users

want to pay parking fees using tokens or virtual money. It has dual functions.

They are a total parking tariff notification online and to reduce the leakage of

parking rates because parking users are not given tickets by park officials.

Moreover, it can find out the position of the vehicle in the parking area. By using

the GPS Module, it will send data to Arduino Uno if the vehicle is in the parking

area. Furthermore, it will activate the initial parking time with the Wemos D1

Mini controller. Later, it will provide notifications on the user's smartphone using

the Blynk application. Users can find out the total parking rates that will be paid

through notifications on the smartphone and directly cut the balance in the

parking user account progressively. The trial of an opened area progressive

parking system based on the Internet of Things (IoT) produces a tool that is able

to provide modern notifications using wireless or hotspot connections.

Abstract - One of the digital data is a document. Documents can be easily copied

and deleted. Anyone can retype or copy parts of the document. In this paper will

detect text similarity. The more similarity of words there is the more indicated the

document is plagiarism. Winnowing algorithm performs the calculation of hash

values of each k-gram. This method improves the search time with more accuracy

in the detection process. All data selected hash values will be fingerprints of a

document. Fingerprint will be used as a basis for comparing similarities between

text data. The fingerprint value of the winnowing process for each document will

be matched by using the Jaccard Coefficient to measure the similarity of the text.

In this paper results show that the adjustment of the k-gram and window values

can affect the final result of the similarity percentage value. The smaller the k-

gram value, the greater the percentage value.

Abstract - The most important point in network services is security of access in

the port . However, the problem that occurs is an open port or access that cannot

be accessed with authentication that can facilitate unauthorized users to be

accessed by the server. This is the basis for increasing access rights to the server

that is built without having to close the port used by the user. Therefore a port

knocking method is needed. Port knocking is a security system that can perform

a function that is blocking unwanted access. In principle, port knocking

successfully closes all ports on the server. If the user needs access to the server,

the user does a "knock" to use the service, then if the user has finished accessing

the port is closed again. The system built in this study uses three ports, namely

port 22 (SSH), port 23 (Telnet), and port 80 (Web). Port Access time is 10 seconds

each. Based on the results of the analysis and testing of the system

implementation carried out, the results of the system can be run properly and can

improve the security of network systems that are built compared to networks that

do not use Port Knocking security. In research assessing on public and local

networks. According to the results analysis, carrying out a remote server via local

time requires faster time from a remote server through the public. In the SSH

protocol there is a difference in time of 2.42 seconds, Telnet 2.14 seconds, and

Web 2.19 seconds.

Abstract - Many business organizations have information systems, but most still

operate separately as a silo. The problem that arises is that there is ineffectiveness

in the process that is in the application. So the need for an integrated information

system that can access two or more systems in the organization is needed. The

system integration process is carried out using Enterprise Application Integration

(EAI) method at the application interface level. This method is used to integrate

academic information systems (SIAMIK) and library information systems

(SIPERPUS). The results of this study are that both applications are connected

without changing source codes from both applications. The integrated system

Abstract - We are facing the industrial revolution era 4.0 today. The issue of

information technology, disruption technology and employment is very urgent.

Data from the Indonesian Ministry of Research and Technology and from the

Indonesian Ministry of Manpower in 2017 show that Indonesian workers who

work not in accordance with their majors are above 50%. The number of jobs

relevant graduates are an important value for Information System study program

during the assessment by the National Accreditation Agency for Higher

Education. So that needs a system to help students for detecting, identifying, and

directing them to relevant career track using Decission Support System approach.

Profile Matching method implemented with determining of 17 alternatives

(career track) and 18 criteria (competencies: core=60%, elective=40%) based on

IS 2010 curriculum. Whereas weight of each criterion associated with alternatives

is stated in 3 variants (significant coverage, some coverage, not required). The

highest rank shows that those career track is the most relevant to the student's

criteria (competencies). The other uses of those rank is also able to help students

in determining their thesis topic.

Abstract - In any game where the player must face large formations of enemies,

the way the formations are formed significantly influences the difficulty level of

the game. As proper difficulty levels are essential to player’s enjoyment, the

enemy formations need to be arranged properly. In this paper we experimented

with how to procedurally generate enemy formations in a vertical scrolling

shooter game while keeping the difficulty levels proper. Generations of the

formations were done with genetic algorithm where the fitness function

calculated two variables: difficulty curve, which reflects a formation’s difficulty

level, and enemy variety. The difficulty curve took into account difficulty points,

which measured the danger levels of on-screen enemies throughout the game’s

duration. The fitness of difficulty curve of an enemy formation was acquired

through point-by-point comparison between the curve and a human-designed one,

which represented the ideal difficulty curve as intended by the game’s developer,

and calculation of the root-mean-square error. The genotype of an individual was

represented by a 5x40 grid containing enemy genes and empty space genes. We

ran 300 generations in total and each was done in 100 iterations and had 40

individual genotypes. The results show that the amount of enemy genes in initial

genotypes influences the population’s fitness progression. We then discuss the

implications of our findings and possible directions of future researches.

Abstract - Face recognition system is still a topic that is widely studied today,

because it has problems that are quite complex. One problem is related to the

illumination factor, which significantly influences face recognition performance.

One of the methods often used for object recognition problems that is influenced

by illumination factors is the obust Regression, which is also used in this research.

The problem to be solved is related to the performance of face recognition in

various lighting conditions. Using one of the face databases, the Yale Face

Database B Cropped, an experiment was performed on each lighting condition of

the face data. In the Yale Face Database B Cropped, there are 10 individuals,

where each individual has 64 variations of images based on illuminations which

are grouped into 5 subsets according to their contrast level. Experiments are

generally carried out using all subsets as training data and all other data as testing

data, where the results show general face recognition performance (in all lighting

conditions). In this research, experiments were carried out for each subset as

testing data, where the results showed the performance of face recognition in each

lighting condition. The experimental results showed the highest face recognition

performance in subset 1 (98.21%), while the lowest performance is in subset 4

(84.46%). The trend of the experimental results shows that the face recognition

performance of the Robust Regression method is getting better on face data with

a higher level of contrast.

Abstract - Global and local thresholding are two thresholding approaches for

white blood cell (WBC) image segmentation. Global thresholding determines the

threshold value based on the histogram of the overall pixel intensity distribution

of the image. In contrast, adaptive thresholding computes the threshold value for

each fractional region of the image, so that each fractional region has a different

threshold value. In this work, we are assessing both of these approaches for two

threshold values. We extended the Otsu’s equation to calculate more than one

threshold as it originally designed to find only a single threshold value. Adaptive

thresholding first divides an image into fractional-image by considering an

imaginary bounding box that surrounds the location of WBC, which involves the

Gram-Schmidt orthogonalization method. For segmentation performance

evaluation, we compare 35 blood smear test images which segmented by our

proposed method, with their corresponding ground truth image to representing

them in Zijdenbos Similarity Index (ZSI), precision, and recall measurement.

Experimental results show that adaptive thresholding achieves average ZSI,

precision and recall, 92.5%, 91.79%, 94.03%, while global thresholding achieves

30.72%, 23.38%, and 99.39% respectively.

Abstract - The smart city is being developed in many big cities to support local

governments for resources and infrastructure optimization in terms of enhancing

services for the citizen. Large investment costs are required to implement a

communication network for the smart city infrastructure (i.e. Internet of Things

(IoT) devices) using 4G or Wi-Fi networks. This study aims to implement Delay

Tolerant Network (DTN) as a low-cost alternative network for the smart city. We

use Surabaya smart city plan scenario in which smart mobility services are

provided in city transportation and infrastructure. The IoT devices are installed in

numerous locations and continuously transmit messages to the monitoring server

located in the city hall, bus and car employed as a DTN node. In this paper, as a

preliminary research, we investigate the performance of well-known DTN routing

protocols (Epidemic, Maxprop, and ProphetV2) with our proposed protocol

called Spray and Hop Distance (SNHD). The evaluation is performed using the

ONE simulator in terms of the number of delivered messages, the average latency,

and the overhead ratio. The results show the performance of SNHD is better than

the well-known DTN protocols in various conditions when the total size of

delivered messages is large. Unfortunately, none of those routing protocols has a

good performance in all of the scenario conditions. In the future, we desire to

implement this system in real smart city system in Surabaya and do simulation

with more realistic scenario such as real traffic-trace.

Abstract - The problem discussed in this article is related to manufacturing

activities that use styrofoam plastic materials as packaging for electronic goods

that have the potential to damage the environment. Material innovation from

National natural resources is needed to overcome it. The replacement of synthetic

materials with rice husk material as manufacturing raw materials is used as a

keyword in an effort to minimize the impact of environmental pollution. The

study used a trial method of making new material substitutions for the

development of green manufacturing. Modeling and testing of chaff material for

styrofoam substitutes as packaging for manufactured goods has been successfully

carried out with a research performance level of 95%. The resulting husk model

has physical characteristics that are close to those of Styrofoam, namely A4 + T

+ P3 + W + t6. model. Micro-biologically, the husk material is easily broken

down in the soil so that this material does not disturb the living environment when

it becomes trash. While styrofoam material is not decomposed by micro-

organisms in the soil, so that the husk material can be used as a substitute for

styrofoam plastic materials.

[email protected]

Abstract - Manual workers are still commonly found in various work activities.

Manual work done repeatedly with monotonous movements and long working

time has the potential to cause work fatigue. In repetitive monotonous motion it

can overload the muscles. Incorrect work posture can lead to excessive fatigue.

This poor work posture is often caused by the design of work facilities that are

less concerned with conformity with its users. From this study it was found that

the current working method is less ergonomic because the testing with RULA and

OWAS the majority of the indicators are on a scale of 4 and must be changed how

its works. On milkfish management workers, refining milkfish spines, burning

milkfish is a monotonous repetitive work that is not supported by appropriate

facilities. Work posture with a stand and a twist and often bending. This study

aims to redesign the work station to get a good work posture. designing work

stations using 8.2 software jack. Work stations consisting of tables and chairs are

designed with due regard to anthropometry and operator motion requirements.

Design evaluation is done by evaluating the work posture using biomechanical

analysis, using a toolkit analysis that includes analysis of SSP, LBA, RULA, and

OWAS. Evaluation results in workers sitting with a well-built body position, the

direction of the head parallel to the direction of the object subject to work, and

the worker being avoided from the bending position and twist

Abstract - Every electronic device has a disadvantage that is heat generated from

the components contained in the device while operating. The heat that occurs

during the process can affect the effectiveness of these electronic devices. The

cooling fan is directed to a heat source from an electronic device with the aim of

maintaining the device's performance temperature. However, the cooling fan used

still has some disadvantages in terms of dimensions. Therefore, research on

synthetic jets is carried out as an innovation in cooling. This study aims to find

wave characteristics as a source. Optimum frequency selection to support cooling.

As well as the ideal height of synthetic jets to heat sources. The method used in

the research is direct and computer-based data retrieval for CFD. The use of

triangular waves as a source of cooling with a frequency of 80 Hz at an altitude

of 8 cm can reduce rapidly. However, the lowest final temperature comes from a

height of 2 cm which is 28.1 ℃.

Abstract - The issue of climate change is unavoidable and a real challenge,

especially in the world of education. The low mastery of concepts and differences

in perceptions of the concept of climate change makes the threat of climate change

increasingly alarming because people really do not understand it. Good mastery

of concepts makes it easier for students to take notes related to climate change

mitigation and adaptation. This study aims to identify the perceptions and

understanding of students on climate change based on data from the distributed

questionnaire. The results showed that most students still have errors in

perceiving the concept of climate change, especially in the matter of the

relationship between climate change and global warming, ozone layer depletion,

the greenhouse effect. So that it can be concluded that the error of the concept of

climate change is massive and comprehensive for the basic, yet important,

element of society. A smart effort is needed to solve it.

Universitas Negeri Surabaya, Ketintang, Surabaya, Indonesia

Abstract - Large urban areas certainly require transportation facilities and

infrastructure that reach all corners of the city administration area. Inequality in

the number of passengers is unavoidable due to differences in accessibility of

each region. One example of the imbalance in the number of passengers is very

clearly seen in two large terminals serving Surabaya city routes, namely the

Purabaya terminal and the Tambak Osowilangun terminal. This study aims to

describe the effect of accessibility factors on the performance of urban

transportation with the Osowilangun Pond Terminal route based on passenger

perceptions. The method used in this study was a questionnaire survey with 120

respondents. The survey was conducted at the Osowilangun Pond Terminal as a

lonely route location for passengers. The analysis shows that the indicator of the

lack of public transportation modes that serve the route results in the lack of

access to the Ososwilangun Pond Terminal and the impact on the lack of

passengers going to the terminal.

Abstract - The main road that connects the city of Sidoarjo to Surabaya is the

intersection of Gedangan. By 2018 it has reached saturation by having a poor

service level. More severe conditions will occur in the next 10-20 years. One of

the government's efforts to overcome the problem of congestion, damage

structure is the construction of flyover or other alternatives by widening the road.

The purpose of this study is to determine the characteristics of the traffic and to

save vehicle operating costs before and after the construction of a flyover at the

Gedangan intersection. The method for predicting Vehicle Operating Costs

(BOK) is to use PCI method. This study predicts Vehicle Operating Costs (BOK)

to determine cost savings. The scenario for predicting BOK is that 80% of the

vehicle volume will pass the Fly Over, and 20% still use the existing road. The

results showed that the cost savings of Vehicle Operational Costs (BOK) of

existing roads compared to the use of flyover in 2019 was IDR 15 Billion. In 2039

the savings are IDR 77 Billion. Another discussion is that if the road is only

widened without flyover, then the BOK cost savings in 2019 will be IDR 4 Billion

and in 2039 it will be IDR 27 Billion.

make the function generator have relatively large dimensions. With relatively

large dimensions of the tool, making the tool is not easy to carry everywhere. To

make the dimensions of the tool become easier to bring everywhere, the waves

generated by the function generator are not made from analog circuits, but are

made from digital data stored on the microcontroller and then converted to analog

with DAC pins. The method of this research is experimental method. The first

thing began with a literature study of the components needed and then continues

with the making of system design to generate smaller function generator which

can display 4 waves, waves that can be displayed are sine waves, squares,

Abstract - Walking is a non-motorized transportation option that has a large

portion compared to the use of bicycles and traditional transportation. Previously,

the quality assessment of pedestrians was only calculated based on their physical

form. But now the pedestrian ways are not only seen as a facility to support the

human movement but has become a public space. To investigate this, we surveyed

Pahlawan Street, Semarang, Indonesia (N=90). The method using is PEQI

(Pedestrian Environment Quality Index) which is a quantitative calculation based

on the 5 indicators (crosswalk safety, pedestrian traffic, land use, street design,

perceived walkability). We find that the most qualified pedestrian way is Segment

I East (70.35), though the lowest is Segment III East (50.16). In particular, we

find that the percentage of social and optional activity is higher than the necessary

activity that been the user choose in Pahlawan Street.

fluctuations can be caused by several factors, both in terms of material costs and

in terms of labor costs. There are several studies discuss the prediction of the

budget plan, but not to discuss the most influential cost components in increasing

the cost of building a residential house. so that it is not known what costs need to

get special attention to be made savings, from this it is necessary to do this

research so that the estimator can focus on the largest cost component for

alternative swatches so that cost savings can be made. The method used is the

method of quantity take-off. As a result, the average salary and material needs for

housing are 31% for salaries, while for materials it is 69% of the total cost. The

highest order is for the salaries of the first workers, second handyman, third

foreman and the last is the chief handyman. Whereas in the most influential cost

material is portland cement, both concrete iron, third galvalume frame, and finally

aluminum. These prices and salaries need to be considered to make savings in the

planned budget for a residential house.

Abstract - Walking is essential to access public transportation. Previously,

investigating walking satisfaction was done by the tangible scheme. But now the

pedestrian is not only seen as people who use these facilities daily. Through the

pedestrian bridge user’s appraisal, we can understand which factors are more (or

less) important and significant. The elements discussed in this study are walking

satisfaction elements, namely safety, security, convenience, continuity, comfort,

system coherence, and attractiveness. To explore this, we surveyed Basuki

Rahmad Street, Surabaya, Indonesia (N=120). The method using is Importance -

Performance Analysis (IPA) which is a measure of the level of service satisfaction

that enters the quadrants on the Importance Performance Matrix map. In this

method, it is necessary to measure the suitability level to find out how much the

user feels satisfied with the performance of pedestrian bridges. We find that the

most factor that the user unsatisfied is B2 which is lighting in the night, followed

by D1 (hands holder on Pedestrian Bridge that is easy to reach and not rust) and

D5 (Building which can reduce vibration when the vehicle is speeding above it)

*[email protected]

Abstract - Traditional tropical architecture is built using local materials by

applying passive design strategies to fix heat problems so the occupants feel

comfortable and protected. Over the years, climate change causes rising

temperatures and modernization causes the aesthetic element to become

important in urban areas. Modern Tropical is a design trend that is now

developing after the era of modern minimalist trends which not only tried to solve

the heat problem but also the aesthetic problems of tropical architecture. This

research aims to evaluate thermal performance in the modern tropical-style house

in response to climate change and also how they adapt and modify traditional

tropical architectural elements to improve their thermal performance by using the

simulation method with the assistance of ECOTECT software. The results

showed that houses that adapted and modified elements of traditional modern

tropical homes up to 95%, showed better thermal performance. That house can

provide thermal comfort for 7 hours and only 31% of percent dissatisfaction.

Elements of roofs, openings, sun shading, and local material coatings on

traditional architecture are elements that can be adapted and modified in modern

architecture. So, tropical architecture no longer looks old fashioned but more

stylish while responding to environmental issues.

Abstract - Commonly house’s damage under earthquake is because their capacity

inadequate to prevent from collapse, and the masonry wall system is not designed

to resist the earthquake force. However, masonry infill wall is commonly used as

partition and to separate large area with a purposed. Interaction between frame

and masonry infill wall are not good connected to prevent building damage from

earthquake. To understand the interaction between frames and infill wall can be

simulated by numerical method or by Macro-modelling approach. The purpose

of this numerical study is modelled a frame as a single element, a masonry infill

wall as a plate element, and an interface between frame and masonry infill wall

as an elastic spring. The concept of modelling depends on material parametric

provided and the number of elements. Modelling with computational software

facilitate to create material element and model and this modelling is conducted

by Tohoku-coast NS time history seismic. The result shows the frequency

parameter expressively increase from frequency on frame model to frame with

infill wall model, or the time period parameter significantly reduce with the

addition of infill wall. By the addition of mortar thickness which increased the

stiffness also affect the frequency parameter and maximum displacement. The

thickness of mortar brought the optimal value to good response is recommended

with thickness of 0.5 cm to 1.5 cm. The finding is that infill wall gives significant

influence on frame response if the interface of frame and infill wall designed with

industry and technology. In many applications, the working fluid is still a

conventional fluid that still has a low thermal conductivity properties. Nanofluid

is one of the ways that can be used to increase the thermal conductivity. The

purpose of this research is to identify the influence of volume fraction against the

heat transfer rate and effectiveness on shell and tube heat exchanger. The material

used is Al2O3 with difference fraction volume of 0.5%, 1%, and 1.5% on the cold

fluid. The temperature of the fluid used in the heat of 90 °C . The result of this

study shows the highest effectiveness in mixed fraction nanofluid volume of

1.5%, which is 42% with the rate of heat transfer of 7061.93 Watts. Then the

lowest effectiveness obtained on the State mixture volume fraction without

nanofluid, which is 17.7% with the rate of heat transfer of 5666.71 Watts. Thus it

can be concluded that when the fraction of nanofluid is getting higher, then the

volume will increase the rate of heat transfer convection as well as the

effectiveness of the shell and tube heat exchanger.

Abstract - . Tumpeng is one of the ceremonial facilities used almost in every

Hindu religious ceremony. Many people take advantage of these opportunities as

a home-based business. At present the craftsmen encounter obstacles in the

process of drying the cone. Currently the drying process still uses the manual

method, namely by drying it by utilizing direct sunlight. In the previous research,

the product planning for cone drying machine has been carried out, where the

results obtained from this study are an increase in the productivity of the drying

machine from the drying machine which was previously used by the cone maker

of 683.33%. From the results of studies conducted by the hot air entering the

drying chamber from the results of the previous engine design, it is likely that

conditions on level 1 shelves and level 2 shelves have temperatures that are quite

high compared to other rack levels because this air is circulated at level 3, 4.5 and

6. To get the air distribution between the level of the rack evenly, it is necessary

to do a redesign of the tool. The alternative that can be done is by circulating hot

air from rack 1 to rack 6, another alternative is to try variations in air distribution

in the drying chamber by varying the cone seat holes.The redesign method that

was carried out was to replace the existing distribution before the air out of the

level 3 blower in the rack was changed to the air out of the level 1 rack entry

blower, and the cone seat was made varied by random holes, concentric holes and

zigzag holes.From the results of engine redesign after testing the air distribution

in the drying chamber with a random hole stacking model, the highest temperature

is found in almost all shelf levels, except at the level 1 rack the highest

temperature is achieved by a concentric perforated pedestal model that reaches

183 oC. Judging from the hot air distribution, the randomly hollowed cone seat

model provides a more even distribution of hot air compared to the concentric

and zigzag hollow cone seat model.

Abstract - Tracking application is widely used to help outdoor activities. One of

them is used to help tourists who do tourist destinations in group activities.

Tourist tracking application requires data on the position of tourists on earth. This

coordinate data can be obtained using latitude and longitude data from GPS

(Global Positioning System). Coordinate latitude and longitude position of

tourists from time to time are stored in a database. Database Selection for media

storage will determines the level of speed and ease in accessing data. There are

some differences in designing the structure of the MySql and Firebase databases.

Relational Database begins with identification of entities involved in the system.

One entity with another entity is related and has a cardinality level of the

relationship. Relational database implementation in the form of tables in normal

forms that are interconnected. Data will be stored in columns and rows.

Normalization of tables causes high query computation when calling data that

involves many tables. Firebase, which is one of the NoSql databases, in building

data structures is stored in JSON objects. JSON tree structures usually consider

the display of information that will be presented to users. So that the generated

JSON tree has high efficiency and speed in processing data. In this study a

comparison between the design of the relational database structure, namely

MySql and NoSql Firebase database structure was developed. Firebase is more

power full for the development of applications which update data in realtime and

and handle a lot of coordinate data such as tourist tracking applications.

Applications that do not have complex data relations such as tourist tracking

applications are more suitable to use firebase than using MySQL.

Abstract - The background of this research is the increasing of criminalization in

children, one of which is kidnapping of children, Meanwhile many parents have

to work so they don't have enough time to be always close to their children. The

purpose of this research is to develop applications that can help a parents to

monitor the movements of their children's outdoor activities. The application uses

a smart watch to get the child's GPS position and at the same time the device

sends the last position of the child to the firebase database server. Parents can

monitor the child's movements through the android smart phone device in

realtime. The application design uses several UML (unified modeling Language)

diagrams namely use case diagrams, activity diagrams and squence diagrams.

This application requires data objects including parent, child, family and child’s

position (latitude and longitude). The main use cases in this application are

sending position, case view, child location on map and view path of moving each

child. The application can run only if there is an internet connection and the child

uses smart time.

Abstract - Software development has many methods which are divided into

traditional and agile categories. Traditional methods are known as heavy, rigid

methods and have a lot of documentation, while agile is known as a lightweight,

fast and a little documentation method. But there is a traditional method that has

the flexibility and speed like the agile method, namely the prototyping method.

Several prototyping methods are often used in building an application. The

research aims to choose the right prototyping method for building a smart village

application. The smart village application can be categorized as an application

that requires a lot of communication with the user, where the user is a village

community who has a certain culture and has a variety of educational

backgrounds. The results of this study are that prototyping methods that are

suitable for building smart village applications are evolutionary prototyping.

Abstract - . Time-table scheduling in senior high school is complex combinatorial

problem. The scheduling process needs much time and susceptible to human

error. This human error can lead to the violation of hard constraints. Beside the

hard constraints, the good schedule must minimize the violation of soft constraint

to ensure the students’ and teachers’ preference can be satisfied. The aim of this

study was to build the automated scheduling process using adaptive genetic

algorithm (AGA). The AGA implements in this study to flexible the probability

of mutation (pm) based on the fitness. The minimum pm was set to 0.01, while

the maximum pm was 0.2. The experiment shows that the AGA give the better

fitness compared to the original GA. The best fitness reached by AGA was 0.054

with the average of maximum generation was 402. The original GA with fixed

pm 0.1 resulted best fitness 0.045 and the average generation was 387.

Abstract - This paper presents field analyses on the influences of condenser and

evaporator approach temperatures of water cooled air conditioning system for a

shopping mall. The mall building comprises food and non-food retail stores and

uses a centralized air conditioning (AC) system to condition the entire building.

The AC system comprises three chillers with the same cooling capacity. Chillers’

performance parameters included power consumption, condensing and

evaporating temperatures, evaporator-condenser approach temperatures, pressure

drop and cooling capacity parameters were hourly recorded for a period of one

year. Performance characteristics of each chiller were evaluated at different

condenser and evaporator approach temperatures and regression analyses were

also established to examine the correlations and influences of the approach

temperatures on the chillers’ performance. The analyses results showed that the

increase of condenser approach temperature could increase the power

consumption and reduce the coefficient of performance (COP) of the chillers.

While evaporator approach temperature was found to have insignificant effect to

the chiller performance. The results also showed that for the investigated chillers

with condenser and evaporator approach temperatures maintained below 2 K, the

approach temperatures had negligible correlation to the power consumption and

the overall performance of the chillers. At this operational conditions, the water

cooled air conditioning systems could operate at their best possible performance.

Abstract - Chest freezer used in daily life are one of the essential tools.

Uninterrupted power should be supplied to refrigerators in order to maintain

cooling service. Photovoltaic (PV) systems provide an independent, reliable

electrical power source at the point of use, making it particularly suited to remote

locations. For this reason, nowadays, the use of PV solar energy in refrigeration

has been increasing in rural regions. But, the design conditions and operating

performance of a PV-refrigeration system are significantly affected by local

climatic conditions. In this study, a PV-powered chest freezer has been

established to investigate experimentally its daily operating performance.

Operational parameters affecting system capacity and performance were

determined under a tropical climate condition of Bali Island Indonesia. Detailed

results obtained during daily experimental measurements are presented. The

results in overall reveal that solar PV panels applied for stand-alone chest freezer

in hot climate region is amazingly prospective.

Abstract - This article develops mathematical models with structural stages from

predators, immature and mature predators. The predation function of mature

predators follows the Holling II response function. We assume that the immature

predator population has the economic value, therefor the harvesting function is

included in this model. In this model an analysis of the equilibrium point and

stability of the interior equilibrium point is carried out. Analysis of the stability

of the interior equilibrium points is done by linearization method and pay

attention to the eigenvalues of the characteristics of the Jacobi matrix obtained.

Analysis of equilibrium point stability is carried out before and after harvesting.

The result is obtained by each of the three equilibrium points. At the equilibrium

point of the interior with stable harvesting a local maximum profit analysis is

obtained from the exploitation business. Based on the results of the analysis, it is

obtained the value of harvesting business which provides a stable equilibrium

Abstract - The extraction or mining of sand along Buti Beach's lips makes the

coastal tourism condition increasingly insecure and its environment results in

abrasion along Buti Beach and becomes a threat to the surrounding settlements.

This happened, one of which was due to the condition of the people who did not

understand and this condition was made worse by making mining as a result of

livelihoods. The development of tourist areas should involve the community

because the purpose of development is to improve the welfare of the people,

especially the local people. Development through structuring activities needs to

be followed by fostering the potential of human and natural resources in order to

strengthen the economy of the people so that they can participate in the

development of urban facilities and are not marginalized. This research was

conducted qualitatively, by conducting questionnaires, discussions and

interviews. Through discussion and interviews, local responses to alternative

arrangements for users are the main thinking. Alternative structuring is carried

Abstract - Mathematics teaching is a learning process gives an understanding of

mathematical concepts for students. The basic concepts of mathematics must be

embedded well in each student so that understanding concepts at an advanced

level can be easily mastered. Mathematics teachers play an important role

regarding the problems faced by students when learning mathematics in class. A

math teacher in addition to having the ability to master mathematical concepts

well, is also required the ability to manage the class so that students can

understand the concept well and learning achievement is in the high category.

Mathematics is a subject consisting of great ideas that are connected to each other

so that understanding cannot be separated because each concept will contribute

to the other concepts. Most students still say that mathematics is a difficult and

uninteresting lesson, therefore, a teacher needs to apply specific strategies used

in the mathematics learning process so that it can change students' perceptions of

mathematics into an interesting and easy lesson. The use of technology can help

teachers and students learn mathematics, for example the use of GeoGebra

software. GeoGebra software has the benefit of being able to make geometric

paintings that are fast and precise compared to using paper and pencil and the

existence of animation facilities provides a clear visual experience for students

and teachers. One of the geometry concepts is to construct a flat triangle, in this

study the discussion is to determine the special lines on the triangle using

GeoGebra software and then determine the intersection of the special lines of the

triangle.

Abstract - In digital images processing, there are three types of edges based on

intensity changes. Namely, step edges, ramp edges and edges noise. An edge is

defined as a set of pixels where there is an abrupt change in colour intensity over

distance. On-ramp edges where gray levels change slowly, the Gradient Method

is able to detect better. On step edges where the intensity or gray levels changes

very quickly the Laplace method is able to detect better than the Gradient Method.

In this study, three images were used as samples and identified the type of edge

of each image. Furthermore, edge detection is performed with the first derivative

operator Canny and the second derivative operator Laplacian of Gaussian. The

results indicate that for step edges LoG provides better results, whereas for ramp

edges Canny detects better. However, by selecting the right threshold that

matches the σ (standard deviation), Canny is also capable to provide good edge

detection results. The greater the σ value, the threshold was chosen must be small

so that the results obtained are good and easily interpreted. The Canny operator

produces a thinner edge and a firmer boundary between objects and between

objects on the given sigma = 1 value while the LoG operator corrects better,

especially on the steep part of the value σ = 2 compared to the value σ = 1.

Abstract - Bananas besides being a superior fruit plant in Indonesia, banana plants

can be utilized as animal feedstocks, The results showed that the administration

of banana stems as animal feed did not have a negative effect on the appearance

of young sheep, and even showed more nitrogen in comparison with sheep

receiving control rations. Banana skin can be used as a substitute feed for

livestock, especially in broilers. Banana skin has been used as poultry feed, a

mixture of banana peel and coconut pulp with a ratio of 2: 1 can be used up to

15% substitute for corn in broiler feed. Banana skin fermented with probiotics

can increase crude protein content by 14.88% and rough seats by 11.43% which

is good for broiler growth. Drought that occurs every year is the main limitation

of the growth of banana plants. Drought in plants can result in slow leaf area

increase and influence on the rate of photosynthesis so that it can reduce

productivity and growth of plants. PEG 6000 was used as an effort in early

detection of genotypes from plant varieties that tolerated drought stress. So far

there has never been a study of plantain feathers against drought stress using PEG

6000. So this research is interesting to do. This research was conducted to obtain

candidates for plantain plantain which are tolerant to drought as animal feed

Abstract - Production of chicken eggs will decrease below 30%, with a

maintenance time of more than 1.5 years, but the old chicken eggs can still be

consumed. The decline in chicken egg production does not necessarily reduce the

quality of eggs chemically, but physically that these chicken eggs have

advantages and disadvantages. The advantage is that it has a large size and

weakness is that some shells are not normal. Therefore studies related to egg

quality chemically need to be done to determine whether there is a decrease in

egg quality in old chickens. Egg quality is generally influenced by feed and

drinking water, some herbal plants given to chickens are thought to be able to

improve the quality of chicken eggs. Some herbal plants that can be used include

turmeric, ginger, cutchery, and red fruit extract. Red fruit has several good

antioxidant compounds and fairly high xanthophyll. The purpose of this study

was to determine and improve the quality of old chicken eggs. The method used

in this study experimentally with 4 treatments and 10 replications. The variables

observed were the quality of protein, fat, cholesterol, bacterial contamination and

the content of omega-3 in eggs. The results showed that the average protein

content was 10 -13%, 9-10% fat, cholesterol 331 - 338 mg / 100 g and Salmonella

SP (negative). The conclusion of this study is that chemically the quality of old

chicken eggs given herbs in the normal range and the administration of herbs do

not improve egg quality physically.

Abstract - This study aimed to compare between Elandt-Johnson and Heligman-

Pollard interpolation method in estimation of a complete life table for erderly.

The range age started from 60 to 110 years. Rapidly increasing of elderly

population both developed and developing countries has encouraged the

government to provide programs for elderly to not assess the productive age. Life

table provides data to estimate the elderly population. However, the data usually

contains data aged 0 year. The neccessity to enable to find out the elderly data

requires a life table. Yet, the problem occurs in some developing countries are

that they do not provide a complete life table and only an abridged life table.

Therefore, the study investigated a proper method to estimate the elderly life table

by comparing the two interpolation methods such as Elandt-Johnson and

Heligman-Pollard method. The results of the study found that the Elandt-Johnson

method was more appropriate than the Heligman-Pollard method to estimate a

complete life table of elderly by comparing the error value.

Abstract -- One of the most common inhibiting factors in the archipelago is the

lack of availability of material resources and human resources. One of the options

is the use of lightweight concrete precast using materials around the islands. The

local material which is widely distributed in North Maluku is pumice but it has

not been used maximally because so far it has only been used as pile material.

This study aims to analyze the effect of partial substitution of pumice on fine

aggregate in a concrete mixture. This research was carried out experimentally in

a laboratory using UTM and divided into 2 stages. Stage 1, designing and

analyzing concrete mix using pumice compared without using pumice, Phase 2

testing using concrete beam dimensions of 600x150x100 mm with an inter load

of 150 mm. Beam test results show that the limited use of pumice in a concrete

mixture does not greatly affect the strength of normal concrete beams, as

indicated by the deflection value and strength of concrete blocks that are almost

as large.

Abstract -- Sand beach has been widely used at the archipelago as fine aggregate

in concrete mixture. Concrete beam specimens consist of 12 beams with 10x15

cm and a length of 120 cm of size. control beam (BN) was made from normal

aggregate with steel reinforcement. the Variation of beam specimen (BF1, BF2,

BF3, BF4, BF5) was made from sand beach's fine aggregate with bamboo

reinforcement. Bamboo that applied as concrete beam reinforcement was Wulung

bamboo kind that have about 3 years of age. bamboo's tensile test results were

obtained average tensile strength is 185 MPa. The flexural test for all beam’s

specimen was carried out with two-point loads to determine the amount of

deflection that occurs in each beam. Analysis of relations of load-deflection was

carried out to each beam specimen from the experiment result. test results showed

that the bamboo reinforcement worked as well expected and no splitting occurred,

so that the bamboo reinforcement appeared broken when ultimate strength

exceeded. The maximum strength was obtained in BF5 beam specimen with an

ultimate load 21,5 kN. Flexural test results show that on beams with steel

reinforcement tends to occur flexural cracks while on beam with bamboo

reinforcement also found shear cracks.

Abstract - Today, the smart city has become a trend in the world and in the city's

governments in Indonesia. The typical geographic condition of the city,

municipality and district government in Indonesia is more directed to the

governance of island governments that have own factors, challenges and

opportunities. One of the visions of the archipelago’s government is the Smart

Islands vision, which is to make the islands become a smart city with connected

islands, integrated, collaborations between stakeholders and improved public

services with own local wisdom. However, the readiness level, the actual

problems found in the existing conditions are not yet evaluated and measured. In

this study, we conducted a smart city readiness assessment with the adoption of

the Nusantara Smart Government Model (NS-GM), which was combined with

the Model SPBE instrument on Presidential Regulation No. 95 on 2018 as the

official regulation of the Indonesian government. We choose 2 case studies as an

example of an archipelago’s government in Indonesia, namely Ternate City and

district's government of Southern Halmahera because the area has the criteria as

a government of an island region that has a vision of smart islands. Smart cities

readiness assessment results show that 2 case studies that are measured in

readiness, are generally still in the pilot stage with values in the 2 towards 3 phase

model that we used

*[email protected]

Abstract -- Acid Mine Drainage (AMD) is one of environmental concerns of

mining activities and need to be prevented. One of AMD prevention method is

passive method by blending PAF Material with Non-Acid Forming Material. One

of constraint often faced by mining companies is the limitation of NAF material.

Other Non-Acid Forming Material that is available and abundant near mine site

is fly ash from Mine-Mouth Coal-Fired Power Plant Banjarsari. The Study of

usage of fly ash as a blending material with PAF material in order to prevent

AMD is deemed necessary. Different blending simulations of varying PAF

material size (fine and coarse) and varying fly ash-PAF Material ratio (2:1; 1:1;

and 0,5:1 by weight) are made and leachate water from kinetic test is physically

and chemically tested. This study result shows that variation in OB-Claystone

grain size is not influencing the acidity of leachate water. Blending FA with OB-

CS with minimum ratio of 1,12:1 (by weight) is effective to prevent AMD

generation. Acid-base equilibrium is met when ratio of mole-transfer between

neutralizing mineral (periclase, lime and gypsum) to acid-generating mineral

(pyrite) is 1:1 (by weight). The higher ratio of FA in blending, the lower oxidation

and alkalinity-production rate. Rate of oxidation of pyrite and alkalinity-

production rate is the same at OB-CS and FA blending ratio of 1:1,62 (by weight).

Abstract -- In designing of Remotely Operated Vehicle (ROV), the most important

issue is how to formulate the movements of the vehicle. This paper proposes the

mathematical model of ROV movement. Combination of statics disciplines and

dynamics of ROV movement are needed to formulate the mathematical model of

ROV. Statics refers to the forces and moments that work on the physical system

around the equilibrium point, dynamics refers to the effect of force on the

movement of the object. Linear mathematical models analyzed can be combined

or separated by taking into account the circumstances surrounding environment

such as velocity vector of the linear state of the vehicle body (surge, sway and

up) and angular (roll, yaw and pitch). Simulation results show that the movement

of vehicles, both basic and combined movements have reliable characteristics.

Abstract -- East Halmahera Regency in North Maluku Province is a district rich

in natural resources in the form of mining products. Therefore, one of the leading

sectors is mining. Currently, the aircraft operating at Buli Airport are of the ATR

72-600type. It is considered necessary to improve the service capabilities to meet

future demands and support the air traffic flow to and from the economic gateway

of East Halamahera. Additionally, this study aimed to ascertain the number of

passengers who will use Buli Airport in 2032 and assess the dimensions of airside

facilities including runway, taxiway, and apron that will be used by the

Bombardier CRJ 1000 Nextgen planes. From the data obtained, we could estimate

andmake predictions about the demand and availability in the future. The datawas

analyzed using three (3) trend analysis methods:least Squares, quadratic and

exponential. One of the best trends was selected based on the smallest value of

the sum of square error that wasthen used toestimate the number of passengers

and aircraft in 2032. The analysis results estimated the number of passengers in

2032 using the quadratic method and obtained a total number of passengers of

50548 per day,while the corresponding number of aircraft was as many as 861,

with two movements daily. The design results showed the need for the runway to

be 2271 m, 149 x 15 m taxiway, and widening for the apron 97 x 75 m.

Abstract -- A lot of knowledge and techniques of image processing which are

now available are widely various. Much research as well as development is

conducted in terms of detecting ripe fruits, one of which is chili. It is one of the

local commodities that is marketable. The process of being ripe chili is relatively

fast. Generally, to measure ripeness is still carried out manually. The

disadvantage of this method is that the level of accuracy is inconsistent, causing

fruit decay in numbers. On behalf of lowering the risk of fruit decay, the research

conducted uses index pixel method. This means itself is the normalization of

variety illuminated by taking ratio in each group of smallest points in an image

processing. In this study, the image taking of chili using box equipped with black

background is confirmed to be useful in reducing time of segmentation process.

When it is in the process of detecting image by searching for the average of index

pixel, then RGB will be counted using Learning Vector Quantization (LVQ) that

is the calculation utilizing weighing value. As a result, the classification of

maturity level can be seen in the test with a very high percentage value and

influence to detect fruit ripeness, signed by the color of RG pixels (red and green)

by 94.9% correctly detected, the color pixel RB (red and blue) is quite influential

by 93.9% correctly detected, and the color of the GB pixel (green and blue) which

was less influential at 63.6% was correctly detected.

Abstract -- High Frequency (HF) radio is a radio wave that works at frequencies

of 3 to 30 MHz with wavelengths of 100 to 10 m, some of the mountainous areas

and islands are still classified as rural areas. Rural areas are rural areas where the

population is not too dense and there are no high-rise buildings.With the presence

of air wave propagation for HF NVIS radio communication at a frequency of 10

MHz that can be used accurately, it can support the creation of communication

systems that have effective service quality and can know the model that matches

the characteristics of the area, making it easier for operators to build a amateur

radio communication network.Propagation is the most important part in designing

a communication network on radio waves that are traversed by having several

bacterial conditions such as analyzing propagation, estimating interference,

estimating cell parameters, reflection or obstacle and distance.VOACAP stands

for Voice of America Coverage Analysis Program. This program is an

ionospheric model that can predict the performance of HF that is expected to use

empirical data.The power received for Ternate-Tidore with a distance of 15 km

is 2,304 Watt, while the transmit power for Ternate-Moti with a distance of 37

km is 3,310 Watts and the transmit power for Ternate-Makian is 1,708.

Sendangan for the simulation on VOACAP is 7,943 Watt for Ternate-Tidore,

5,011 Watt, for Ternate-Moti, install 3,981 Watts for Ternate-Makian, this shows

that VOACAP software has a greater signal than the calculation

Abstract - Provision of drinking water is strived to meet 4k items (quantity,

continuity, quality and affordability. Tidore Island is a small island with domestic

and non-domestic water needs until 2018, which is 125.21 liters / second and in

the projected year of 2,038 it reaches 167.98 liters / second. From the existing

data, the average water source in the form of deep wells on Tidore Island is 2.5 -

5 liters / second, so we need around 60 deep wells, so that it is very burdensome

for operational and maintenance costs. which is located on the east side of Tidore

Island, is one area that has the potential of raw water for drinking water that can

be planned with the concept of green water supply, namely making shallow wells

with depths between 24 - 40 meters below ground level and pumping them into

reservoirs with a capacity of 500 m3 at an altitude 469 m and utilizes the

distribution pipe as a rapid pipe to rotate a mi water turbine hydro hydro installed

at a height of 134 m. From the results of the analysis it is predicted that the

potential of ground water in Rawa Lembah Keramat Talaga village around 55

liters / second will be planned with a capacity of 50 liters / second and electrical

energy of 105 kW will be assumed assuming total turbine efficiency of 65% with

a height difference falling 346 meters. Based on the calculation of electrical

power requirements for pumps with a capacity of 50 liters / second the head of

120 meters is 98 kW, so it can be concluded that the electrical energy generated

by micro hydro is able to meet the energy requirements of raw water pumps.

especially in estimating reserves. This research was conducted to model the

geometry of lateritic nickel ore deposition on heterogeneous blocks using the

geostatistical estimation method Ordinary kriging (OK) and simulation methods

namely, Sequential Gaussian Simulation (SGS) then the distribution of laterite

zonation was carried out to calculate the resource and mineral resource

classification based on estimation data and simulation. The estimation results

using the OK method have an average value of Ni higher than the average Ni

grade from the SGS simulation results. Analysis of the calculation of total

tonnage of resources from the estimated OK data shows the total amount of

measured tonnage of 5,875 tons is far lower than the amount of resource tonnage

from the SGS simulation data which displays the total amount of tonnage

measured 189,766 tons. However the average grade of Ni from measured OK

Resources is 1.49% higher, compared to the average Ni grades from measured

resources of SGS 1.33%. with a difference of 0.16% Ni grades. The opposite

occurs when the average Fe grade of the measured OK resource is lower 24.15%

compared to the average Fe grade of the Measured resource of SGS 32.81% with

Abstract -- This research was conducted at Sultan Babullah Airport in Ternate.

Primary data was collected by interviewing airport passengers and visitors and

direct observation (filling out questionnaires), while secondary data was obtained

from reports, articles and service operational standards. Data were tested using

validity and reliability tests and analyzed using the mean analysis method

(looking for average values). The results of data analysis show that the quality of

public services at Sultan Babullah Ternate Airport is quite maximal, there are

only a few service facilities that are problematic, where negative ratings from

passengers are more dominant than the positive rating. Positive ratings are

"Appearance of airport officers" (mean 3.90), "Cleanliness, room neatness"

(mean 3.88), "Airport security" (mean 3.66). Negative assessments in the form of

"Reliability of waiting room facilities (including toilets)", "Availability of seats

in the pickup room", and "Ease of reaching the airport". For a negative (invalid)

assessment there is no mean because invalid data is not included in reliable

calculations and mean analysis. If viewed in groups, the highest level of service

quality includes "Tangibility" (mean 3.70), "Assurance" (mean 3.60),

"Responsiveness" (mean 3.55), "Reliability" (mean 3.38) and "Empathy" (mean

Abstract - Recently, The industrial sector produces about half of the worlds total

energy consumption. Manufacturing companies are required to reduce energy

consumption. This article aims to develop a Hybrid Whale Optimization

Algorithm (HWOA). We use the objective function of minimizing energy

consumption. It solves the problem with permutation flow scheduling problems

(PFSSP). Dependent sequence setup is a PFSSP problem with setups that depend

on schedule sequence. We offer HWOA with local search strategies. The solution

in each HWOA iteration is improved using flip and swap mutations. Furthermore,

HWOA is compared with several algorithms. We use numerical experiments to

show the performance of the proposed algorithm. Comparative analysis with

several algorithms has previously been carried out with ten variations of PFSSP

problems. Based on numerical experiments, HWOA proved to be competitive

Abstract - Advances in technology have increased the use and complexity of

software. The complexity of the software can increase the possibility of defects.

Defective software can cause high losses. Fixing defective software requires a

high cost because it can spend up 50% of the project schedule. Most software

developers don't document their work properly so that making it difficult to

analyse software development history data. Software metrics which use in cross-

project software defects prediction have many features. Software metrics usually

consist of various measurement techniques, so there are possibilities for their

features to be similar. It is possible that these features are similar or irrelevant so

that they can cause a decrease in the performance of classifiers. In this study,

several feature selection techniques were proposed to select the relevant features.

The classification algorithm used is Naive Bayes. Based on the analysis using

ANOVA, the SBS and SBFS models can significantly improve the performance

of the Naïve Bayes model.

Abstract - The study of the behavior of embankments reinforced by geosynthetic

construction on soft clay soil with and without a prefabricated vertical drain is

described. The effect of a pre-loading with stage construction method to construct

the embankment, the gain of bearing capacity, as well as the depth of

compressible soil was also considered in this study. The limit equilibrium using

Bishop and Fellenius methods was used in this study to determine the stability of

the embankment. Vertical drain installation, combined with the stage construction

method, substantially reduces the number of geotextile reinforcements needed.

The number of geotextiles can be reduced by up to twice that compared with

foundation soil without PVD. Furthermore, the combined use of geotextile and

PVD can improve the performance of embankment height as well as increase the

critical height of the embankment with geotextile reinforcements. Without PVD,

the embankment will be safe against landslides (without geotextile) of less than

3.5 meters. When using PVD, the embankment critical height can increase by up

to 7 meters. This condition occurs when the embankment is constructed using the

stage construction method, geotextile reinforcement, as well as PVD installation

for soil improvement.

Abstract - Iridology, which is an alternative diagnosis that links iris patterns,

colour, tissue weakness, damage and other characteristics, which can obtain

evidence about the patient's systemic health. Iridology can be integrated with the

best technology such as computer vision for accurate identification of

abnormalities in various organs of the human body. By extracting information

from iris image data. Image quality improvement is needed because often the

images tested have poor quality, for example images experiencing lighting, noise

(noise), the image is too dark or bright, the image is not sharp, and blurred. In this

research, the iris image quality was improved by the method of HE, AHE and

CLAHE. The results of the improvement of 40 iris images obtained an average

value of MSE and RSME, the smallest of the three methods is the CLAHE

method, so that the CLAHE method is best used for iris image improvement.

Overall, based on the PSNR values, the three methods are good for enhancing

image contrast because they have an average PSNR of more than 30dB.

Abstract - Indonesia is a country located between three tectonic plates thus very

vulnerable to natural disasters. Ensuring that supports for disaster victims arrive

on time and precisely in quality and quantity is the responsibility of all the supply

chain elements, particularly government board which handled the logistic

support. The activities of the supports supply chain when a disaster occurs have

several risks that must be asses and the most prioritized risk will need the

mitigation design to minimize the impact of these risks. This study aims to

investigate risk events and risk agents in the supply chain activities in relation to

disaster management in Aceh. This study employs three government boards at the

key stakeholder's group who play a significant role in the disaster risk mitigation

in Aceh. Data obtained from questionnaires are used for analysing the supply

chain activities using the SCOR model and Fuzzy-Based House of Risk method.

The study reveals that there are 25 risk events ad 27 risk agents which might occur

in the supply chain activities during disaster in Aceh. The mitigation strategy is

proposed in mind map models with a long term solution for each risk agent related

to the potential risk events.

Abstract - The global supply chain allows companies to distribute their product

all around the globe. The companies have to prepare themselves with an

integrated system that is involving the possibility to deliver the product to the

farthest area within their regional target. However, the limited due date of

products generates the distribution and inventory problem that is complex and

challenging to solve. One of the methods to solve the distribution problem of

products with the due date is to use the system thinking approach to identify the

root of the problem. The Economic Order Quantity (EOQ) method is the most

reliable method to discover the most cost-effective strategy, especially for

products with the limited due date. The company for this case study is PT Y. The

main problem of the company is stock out. The result shows the root of the

problem in this company is the unstable demand from the customer, storage

management, and distribution management. There are similarities between the

three root problems. The due date and quantity are the factors that control the

three root problems. The result also shows that the EOQ Model that is taking the

due date into account is more expensive than regular EOQ model

Abstract - Malang city government created Bank Sampah Malang (BSM) that

offers 3R concept (reduce, reuse, and recycle). BSM is the institution which is

oriented toward reducing plastic waste, but their recycling process still has not

considered the environmental aspect yet. In this paper, we developed a reverse

logistics model for plastic bottle recycling in Bank Sampah Malang (BSM) with

consideration minimizing the costs of reverse logistics and environmental

impacts. The proposed model takes into account various parameters, including

kinds of costs, availability of used plastic bottle, storage capacity, disassembling

capacity, vehicle capacity, and demand of chopped plastic. Goal programming is

used to formulate mathematical model and LINGO is applied to solve the model.

Lingo results indicate the two goals have been achieved because the value of the

positive deviation variable associated with the two goals are equal to zero. In

addition, we got several decision variable solutions including: number of plastic

bottles purchased from depot, number of bottle bodies moved to recycling area,

number of bottle bodies recycled, and amount of chopped plastics delivered to

firm

Abstract - Examination timetabling is included in the category of

Nondeterministic Polynomial- Hard (NP-Hard) problems, namely problems that

cannot be solved by conventional methods in finding optimal solutions. One

solution to this problem is to use the Simple Random - Hill Climbing - Hyper

Heuristic (SR-HC-HH) approach. But this approach still cannot produce an

optimum solution. The researcher presents a critical analysis of the performance

evaluation of the solution method used. The stages of this research include: (1)

problem identification; (2) literature study; (3) data retrieval and understanding;

(4) translation of mathematical models into data structures; (5) evaluation of the

SR-HC-HH algorithm; (6) trial implementation; (7) algorithmic experiment

parameters; and (8) analysis of results and conclusions. SR-HC-HH algorithm

used in Hyper-Heuristics-based applications is able to solve timetabling problems

in the Examination Timetabling Problem domain in the ITC-2007 dataset, but it

is still not optimal. Parameters that can be changed in this study are the number

of iterations (time limit) and algorithms for selection of Low Level Heuristics.

Changing parameters in the trial scenario can also affect the results of a more

optimum solution. The parameters to be explored in this study include LLH

selection strategies and move acceptance in hyper-heuristics.

Abstract - Indonesian government has an organization that aims to manage basic

necessity nationally, especially for rice commodity. The organization runs in the

form of a business entity and has a program making welfare of the poor people

by providing rice assistance. There is still over stock and out of stock in inventory

while organization distributes this relief. That matter creates unbalance between

commodity in inventory and commodity in distribution incurring a large cost.

Prediction model using system dynamic in this study was needed to control the

inventory and reduce over stock or out of stock. Causal loop diagram was used to

describe the relationship between variables in the system and simulation was run

with stock and flow diagram. Simulation was done by benchmarking the actual

and the simulation results. The model that was built, tested using the Mean

Absolute Percentage Error (MAPE). Based on the simulation results, the values

of MAPE are below 5%. This indicates that the model can represent the real

system and can use to predict variable for the future.

Abstract - The concept of Smart City has now become the primary choice and

trends in improving the quality of public services and is expected to be a solution

to problems that occur in urban areas that are increasingly complex by offering

an integrated ICT-based city governance concept. However, there are significant

differences between the concepts of City and Regency in terms of government

structure, area, livelihood variations, population, economy, and socio-culture. So

that the idea of Smart City is not always probable and valid if applied to the

District. This study aims to create a Smart Regency Framework Model that is

different from the Smart City Framework Model, which has been widespread.

The method used in this research is Meta-Ethnography to synthesize qualitative

findings of regency building factors and TOGAF ADM 9.1 to develop an

information system architecture model. The results are expected to produce a new

Information Systems Architecture Model and contribute to the development of

smart district service models.

Abstract - A Conventional distribution transformer consists of bulky windings,

cores and coolant liquid hence it is weighty and large in size. Now days,

supporting by development of power semiconductor devices, the idea to develop

distribution transformers using switching power converter technology becomes

viable. This paper proposed a new structure of a solid state transformer (SST) for

power electrical distribution system. The proposed SST works without utilizes

high frequency isolating transformer. Instead, high gain cascaded Buck

converters are used. The design of Buck Converters involves calculation of the

applied components such as Inductors and Capacitors. Simulation result verifies

that Buck Converters work well to reduce DC voltage of 25 kV DC voltage to

620 V DC without excessive ripple. The proposed SST is successfully operated

to step down 20 KV of AC voltage to 400 V with THD of output voltage less than

2 %.

Abstract - Yellowfin tuna (Thunnus obesus) is one of the most important and most

caught fish in the eastern Indian Ocean off west Sumatera and has extensive

migration. To develop an appropriate prediction model and to understand the

contribution of oceanographic parameters in the potential habitat of Yellowfin

tuna, remotely sensed data and habitat modeling were used. Daily data of sea-

surface temperature (SST), sea-surface salinity (SSS) and sea-surface height

(SSH) were downloaded from the marine copernicus website, meanwhile fishing

vessel position for Yellowfin tuna were obtained from fishing port Samudera,

Bungus, west Sumatera, from January through December 2015. Daily fishing

vessel position and environmental parameters were used for maximum entropy

model construction. The model predictive performance was then evaluated using

a threshold-independent metric, the area under the curve (AUC) metric of the

receiver operating characteristic (ROC). Maximum entropy model results (AUC

> 0.90) indicated its potential to figure out the spatial distribution of Yellowfin

tuna. In general, SST (50.5%) is the most affective variable in the Yellowfin tuna

distribution, followed by SSS (37%) and SSH (12.5%). This study showed that

integration multi remotely sensed data and a modeling approach provide an

innovative way to decide the potential fishing zones of the Yellowfin tuna in the

eastern Indian Ocean off west Sumatera.

Abstract - The common problem occurs in fish mapping using autonomous

surface vehicles (ASV) is pitching stability. Some researchers have indicated that

problem affects the results of mapping. The target of this system is to design an

Autonomous Pitching System (APS) for ASV using numerical simulation

software. The simulation is done by implement APS into the system, producing

an oscillatory motion from the ASV. For both dynamics of craft in short and long

periods, APS with proportional controller (P), proportional-integral controller

(PI), and proportional-integral-derivative controller (PID) are developed in order

to minimize the oscillatory behaviour. It was found that for the short period

dynamics, the APS with PI controller was the optimal controller, followed by the

PID controller and then the P controller. For the long period dynamics, the APS

with PID controller was optimal.

Abstract - Lung is one of the vital respiratory organs in the human body. Where

during respiration, there is a process of gas exchange in the lungs by taking

oxygen (O2) from the air and releasing carbon dioxide (CO2) into the air. Because

in the process of respiration involves air in the surrounding environment, the more

contamination of air is inhaled, can cause various lung diseases. If the lung

diagnosis is done early, then lung disease can get health care earlier. Chronic

Obstructive Pulmonary Disease (COPD) is a type of disease that blocks the flow

of air into the lungs due to swelling and mucus or phlegm, so that the sufferer has

difficulty breathing. In making this research, we want to make a design tool to

detect COPD and determine its severity using medspiro (medical spirometer).

COPD can be diagnosed by measuring the value of Forced Expiratory Volume in

One Second (FEV1), Forced Vital Capacity (FVC) and comparing it with

predictive values of FVC and FEV1. The results obtained from the manufacture

of spirometers have FVC measurement errors of 5.8950%, and FEV1

measurement errors of 10.5030%.

Abstract. The abundance of cassava cultivation production in Indonesia needs to

be balanced with the use of cassava itself to be a source of alternative food as rice

subtitute. In this research was done the drying of tubers grater which was cassava

to be dried into flour. This drying used a mechanical dryer which was a pneumatic

(flash) dryer by using the heat recirculation method (the heat produced from

drying was reused). The drying in this research was carried out with a variation

of 2 air openings, which were openings for air speed (blower) and openings in the

heat recirculation pipe. For openings in the blower, this research used 2 variations

of openings, which were openings 50% (air speed 0.0603 m/s) and openings 75%

(air speed 0.0768 m/s). For openings in the recirculation pipe, 4 variations of

openings were used, which were openings 0% (without recirculated the heat),

openings 25% (the heat returned was only 25%), 50% and 75%. The drying time

was based on how long the material was in the duct drying. The results showed

that, by doing heat recirculation, the value of heating and drying efficiency would

increase. The drying in air recirculation 25% could increase the value of drying

efficiency for about 5-6%, while in air recirculation 50% could increase the

efficiency value for about 3-4%. The value of the heating efficiency of this

research ranged from 57-86%. The drying rate constant of the cassava grater

moisture content ranged between 0.16 to 0.194%/second.

Abstract: Food insecurity can be seen in terms of production, consumption, and

distribution. The aspect of food insecurity is the ability to produce unbalanced

with the fulfillment of needs. Production capability is not seen from the

availability side, because availability can be met from the inter-regional supply.

The consumption aspect is the inability to buy food because there is no purchasing

power or the poor. The availability of food that does not meet the needs of the

community resulting in food insecurity. Then the way to handle food insecurity

in the region of Bondowoso is by distributing food that requires the shortest path

to overcome the many areas that must be given assistance. Determination of the

shortest path is a problem to find a path between two nodes with a minimum

Abstract. Individuals post-stroke suffer deficiency of motor function and need

more effort to exercise using cycling therapy. Virtual reality augmented cycling

(VRAC) that incorporate compensatory strategies such as manipulation of virtual

environment (VE) may change motor behaviour and increase exercise intensity

while also being engaging and motivating. In this research, we try to examine

perception and vision aspects of individuals post-stroke that affect the user

interface to a VE when driving a VRAC by manipulating VE features such as

gain related with human perception, and width and difficulty of path related with

human vision. To examine those aspects, we divided two groups, namely healthy

sedentary control (n=3) as reference and individuals post-stroke (n=7). From the

examination results, it was obtained that both groups had given a good enough

response to manipulation of VE features although there were no significant

differences to individuals post-stroke when driving VRAC in wide path

conditions. Manipulation of VE features affect cycling behaviours for individuals

post-stroke and assist to transfer visual information in real world to virtual world

for development of post-stroke rehabilitation using VRAC system.

Abstract. Pollution and deterioration in environmental quality are influenced by

many factors, one of which is the existence of industrialization in various sectors

of the economy. Industrial pollution is an industrial activity that causes a decrease

in environmental quality because of the pollution of substances produced into an

environment. Any waste should not be a problem if managed properly, but if there

is limited funds in a company and lack of concern for industrial entrepreneurs,

then the waste is not managed. The purpose of this study is to determine the

impact of the construction of B3 waste treatment plants on environmental quality.

This research was carried out in the Village of Lakardowo, Jetis District,

Mojokerto Regency. Data collection was carried out for 2 months from October

to November 2018. Variable analysis of the impact of sewage treatment plants on

environmental quality included water and soil analysis carried out at the Jember

Polytechnic BioSains Laboratory and odor around the waste treatment plant with

survey methods to the surrounding community.

Abstract. Humans often encounter obstacles in doing their work. Especially if

the work is related to an emergency situation that concerns the safety of human

life, it needs quick and appropriate handling. Telerobotic technology that has a

haptic function is one solution to these problems. In this study a system of 1 DOF

haptic manipulator with slave master configuration was developed using bilateral

haptic manipulator control. In bilateral control the position and information are

transmitted in two directions between two manipulators. Position information is

obtained using a potentiometer and force information is obtained by representing

the force with the current using the WCS2702 sensor. There are three control

methods used, namely bilateral symmetrical position control, bilateral reflection

force control and force feedback bilateral control. The best method of control is

the bilateral feedback force control. In the force feedback bilateral control system,

the slave can move following the master movement with a ± 2⁰ position error.

When the slave arm is held by a hard object, the master arm is also restrained with

± 11⁰ position error. Whereas when the slave arm is held by a soft object, the

reflection of the object is felt by the master arm with ± 10⁰ position error.

Movement of the master and slave arms is lighter than using bilateral control of

symmetrical position.

Abstract. This study was about the effect of kefir grain concentration level and

the different length of storage, as well as the interaction between kefir grain

concentration level and the different length of storage on the fat content, pH and

the viscosity of goat milk kefir (GMK). The ingredients used were goat milk from

Pegumas farmers group and kefir grains from Perwira kefir. Data was analyzed

by using the analysis of variance of 2x4 factorial and continued by Duncan’s new

multiple range test. The results showed that kefir grain concentration gave a

significant effect (P<0.01) on the fat content, pH and the viscosity of GMK. The

different length of storage gave a significant effect (P<0.01) on the fat content,

pH and the viscosity of GMK. The interaction had no significant effect (P>0.05)

on the fat content and there was an interaction effect (P<0.01) on the pH and

viscosity of the GMK. The conclusion of this study was the increase of the

concentration level of kefir grain up to 3% resulting on the lowest fat content and

pH, and the highest viscosity; and that the length of storage up to 21 days

decreases the fat content and pH, but increases the viscosity.

Abstract. Integrated surveillance of ARI disease at Health Office of Jember is still

using manual method in reporting in which the officers have to come directly to

the Health Office to collect the data. The problem emerged of this manual method

is the difficulty of designing the report because the officers have to recap and re-

search the data of the report, and the data collection process is often late due to

the far distance of the health center to the manual health office. This research was

intended to create a design for data recording and reporting system of integrated

surveillance of ARI disease in order to facilitate the reporting process to the

Health Office. The method used was waterfall method with the stages of need

identification, designing system, Website implementation, integration, and

testing. This research used qualitative approach, in which the data were collected

through the interview, observation, and FGD. The script editors used were PHP

program and Sublime Text3. The result obtained from this research was the

information system of integrated surveillance report of ARI disease. Thus, it is

suggested to increase the distribution of component data related to the integrated

surveillance report in order to decide the action planning of ARI disease.

Abstract. Recently, cake becomes increasingly popular to consumer because of

its sweet taste, unique and interesting shapes. The objective of this study was to

assess the effect partial substitution of pumpkin powder on the quality of cake.

Cakes were made by partially substituting wheat flour with 5% to 25% of

pumpkin powder. The physical, chemical and sensory properties of cakes were

evaluated. Pumpkin peel powder (PPP) significantly affected the physical,

chemical and sensorial properties of enriched cakes. Specific volume of enriched

cakes decreased as the PPP enrichment increased. Darker, reddish and yellowish

color produced with a higher level of PPP enrichment. Nutritional content of

enriched cakes enhanced with higher level of PPP enrichment. Moreover, sensory

attributes of enriched cakes decreased as the PPP level increased. Thus,

enhancing nutritional content of cakes by enriching with pumpkin peel powder is

feasible, but compromising the sensory attributes of cakes.

Abstract. Concrete which is generally used for building needs must reach the age

of 28 days according to SNI to achieve the maximum compressive strength value

from the plan. Along with the development of developmentthere needs to be

research where concrete is planned so that it can achieve the compressive strength

that is planned and has a higher quality even though it has reached the age of 28

days, this study uses Sikacim® Concrete Additive and Master Ease 5010 as

additional material to obtain compressive strength values wanted. The results of

the research conducted at the University of Civil Engineering Laboratory were

attended by K-300 concrete planning using additional material Sikacim®

Concrete Additive and Master Ease 5010, from the results of the above studies

can be seen the compressive strength when 7- day concrete concrete has reached

the compressive strength the average value of 251.56 kg / cm² from there is the

role of additives that function to accelerate the hardening of the concrete .

Furthermore, for 28 days old concrete has exceeded the planned target of reaching

an average value of 316.44 kg / cm². And the last concrete test when it was 56

days has a value of increase that is high enough to reach an average value of 3

34.22 kg / cm², here the role of the second additive substance begins to be seen

where when the concrete is over 28 days still has a fairly high increase.

Abstract. Concrete is a component that has an important function for buildings,

both in the form of buildings, housing, highways, and other public facilities. The

use of concrete, which is getting longer and higher, also has to maintain the

quality of the concrete. One of the problems in concrete is the problem of

compaction, the existence of cavities in concrete is a problem that if left

unchecked will be fatal, concrete that has an automatic cavity will also reduce the

value of concrete compressive strength, concrete compaction usually uses a

vibrator or vibrator, but in reality the use the vibrator is used in a random way and

does not have a fixed time rule, so the concrete is not evenly packed. This study

discusses the compressive strength of concrete are produced with a mixture of the

same sample but with different rules vibration time sehingga find the time to

achieve the maximum compressive strength of concrete. For the average value of

the highest compressive strength produced by concrete with the duration of

Concrete Mix At 30 minutes and vibrator for 5 minutes with strong average value

press concrete reaching 202.67 kg / cm². While the value of the lowest

compressive strength is produced by concrete Duration of Concrete Mix At 30

minutes and vibrator for 10 Minutes above can be seen strong average value press

concrete reaching 158.22 kg / cm²

Abstract- The wound healing process consists of three phases, namely the

inflammatory phase, proliferation, and maturation. An increase in the number of

neutrophil cells and macrophages signifies an inflammatory phase. Fibroblasts

and epithelialization indicate a proliferation phase, whereas in the maturation

phase is marked by the occurrence of wound healing. Ginger (Zingiber officinale

Roscoe) contains active substances, namely triterpenoids, flavonoids and

saponins. Flavonoids function as anti-inflammatory. Although it has many

benefits, the effect of giving ginger extract to neutrophil cells, fibroblasts, and

epithelial thickness in incision wounds has not been studied. The purpose of this

study was to determine the effect of ginger extract on the number of neutrophil,

fibroblast cells, and epithelialization in incision wounds. The research design

used was post test only control group design. Rats were divided into control

groups given 1% CMC solvents and the treatment group were given oral ginger

extract at a dose of 1 g / kg BW. The tissue was observed on days 1, 5 and 10.

Based on the results of the Kruskall Wallis test, the p value was 0,000 with α 0,05,

so it can be concluded that the administration of ginger (Zingiber officinale

Roscoe) can reduce the number of neutrophil cells, increase the number of

fibroblast cells, and increase epithelialization of incisional wounds in white mice

(Rattus norvegicus).

pose a threat of death. In addition to the physical condition of people with

HIV/AIDS worsening, the presence of social pressure can also cause stress in

people with HIV/AIDS. Initial Survey that has been done shows the high

incidence of stress in people with HIV/AIDS. Stress management can be done by

pharmacological and non-pharmacological methods. One of the non

pharmacological techniques that can reduce stress on people with HIV/AIDS is

Autogenic Training. Autogenic Training is a method of stress management using

a holistic approach. The purpose of this research is to determine the influence of

Autogenic Training on the level of stress in people with HIV/AIDS. The design

used in this research is one group pre-experimentation designs by using pre-post

test design design. Samples in the study of a number of 20 people are selected

using the purposive sampling technique. The statistical test used in this study is

test Wilcoxon Signed Ranks Test. Statistical test results showed an influence on

the administration of Autogenic Training on the stress of people with HIV/AIDS.

Abstract. The purpose of this research is to prove that the anthocyanins of purple

sweet potato can lower the Fas expression of epithelium cells of endometrial of

white rat menopause model. The design of this research is true experimental with

Randomized post only control group design. The experiment animal used is a

white rat (Rattus norvegicus) females aged 9-12 weeks with a weight of 150-250

grams, a number of 30 rat are divided into 5 groups i.e. negative control groups,

positive control groups as well as groups with administration of Anthocyanins of

purple sweet potato dose 20 mg/kg BW (A1), dose 40 mg/kg BW (A2), dose 80

mg/kg BW (A3). Performed ovariectomy and awaited until the 28th day of the

post ovariectomy then it was given the exposure to the anthocyanins of purple

sweet potato for 30 days. Fas expression is examined using IHC. The Data were

analyzed and tested by independent sample T Test and One Way Annova. Results

showed that the administration of anthocyanins of purple sweet potato is proved

to decrease the expression of Fas significantly in the endometrial epithelium cells

at a dose of 40 mg/kg of BW and 80 mg/kg of BW. This is because a purple sweet

potato anthocyanin acts as an antioxidant capable of lowering cell death on an

extrinsic pathway. Cell death through an extrinsic pathway involves Fas proteins.

Based on the results of the analysis showed that the anthocyanins of purple sweet

potato was able to lower the Fas expression of epithelium cells of endometrial

white rat menopause model.

count cell and opportunistic infection among HIV/AIDS patients. The design of

this research is analytical observational by using Cross Sectional approach. The

data are taken restrospectively based on medical record of the patients in Mardi

Waluyo Hospital in Blitar from March to July 2018. The diagnosis is done by

ELISA laboratory Checking. The number of sampling are 48 patients which is

got by purposeful sampling technique. From 48 subjects of the research, there

are 16 men and 32 women. The result of this study reveals that CD4 count cell of

HIV/AIDS patients is 165.27 cell /mm3 in average. The lowest CD4 count cell is

25 cell /mm3 and the highest of CD4 cell count is 450 sel/mm3. The patients of

HIV/AIDS who get opportunistic infection is 68.8%, and those who have not

opportunistic infection is 31.2%. The analysis using spearman-rho shows that

there is correlation between CD4 count cell and opportunistic infection with

p=0.00 with strong correlation (r=0.732). It is hoped that the result of this study

can be a new literature, and can be discussed about add value of CD4 count cell

in managing of HIV patients who get infection, so it can be managed

opportunistic infection early.

Abstract. In the process of construction and post-construction, various problems

can often be encountered, with one of them being damage to the concrete which

can cause weakening of the concrete structure or damage to the concrete structure.

Therefore, the need to prevent such damage by analyzing the causes of damage

can be minimized. This research was carried out in collaboration with the

contractor, where the first step taken was direct observation and interviews with

the implementing contractor. By aiming to get primary data and secondary data

so that data conclusions can be made and knowing the causes of damage to

concrete structures in the construction phase can then provide advice on

preventing damage to concrete structures that can be done. Based on the results

of the study, it was found that the potential causes of damaging the concrete

structure in the construction phase were problems with the height of the fall of

casting, errors in construction, execution, vibrators, and errors in the installation

of begisting.
