Dean’s Foreword
May peace and God’s blessings be upon you all.
On behalf of the Committee, first of all allow me to extend
my warmest greeting and welcome to the International
Conference of Chemistry 2018 organized by Department of
Chemistry Education, Yogyakarta State University.
In the modern and globalization era, the development of
science and technology cannot be separated from our daily
lives. It becomes one of aspects that should always be
improved. The science and technology development could be
achieved if it is supported by the improvement of firm fundamental knowledge.
Chemistry and Chemistry Education have an important position on that development.
The empowerment of those fields through research and studies should be done
continuously.
With the theme of Optimizing and Empowering Chemistry of Sustainable Development
of Science and Technology, this conference is aimed to pull together researchers,
scholars, professionals, and practitioners to share their critical thinking and research
outcomes. Therefore, we are able to understand and examine the development of
fundamental principle, knowledge, and technology. By perceiving the matters and
condition in research and education field of chemistry and chemistry education, we
could take a part in conducting qualified education and steps to reach out the developed
science and technology.
This conference will be far from success and we could not accomplish what we do
without the support from various parties. So let me extend my deepest gratitude and
highest appreciation to all committee members. I would also like to thank each of
participants for attending our conference and bringing your expertise to our gathering.
Should you find any inconveniences and shortcomings, please accept my sincere
apologies.
To conclude, let me wish you a fruitful discussion during the conference. Have a very
pleasant stay and enjoy the cultural, historical, and natural beauty of Yogyakarta.

In the present scenario energy needs of our rapidly growing population continue to expand; a significantly larger fraction of our energy supply will need to be sourced from renewable sources in the very near future. Rapid depletion of fossil fuels and growing environmental concerns pose serious scientific and technological challenges to address the increasing global demand for energy. In view of these, energy will be the greatest challenge facing humankind in the 21st century. Development of alternative, sustainable, clean energy technologies is needed to address this inevitable challenge. The electrolytes play a vital role in making efficient renewable energy devices most particularly polymer based ones. Why we prefer Polymers? As a technological approach, they are unrivalled in terms of processing cost, processing speed, processing simplicity

The application of chiral derivatizing agents (CDAs) with the NMR shift
difference method is one of the most frequently used protocols to identify the absolute
configuration of natural products. Chiral derivatizing agents, tetrahydro-1,4-
epoxynaphthalene-1-carboxylic acid (THENA) and its derivatives, having a syn-
periplanar arrangement of O–C –C=O as a part of the bicyclic system to lock the
aromatic residue conformation, were introduced. These new CDAs offered good
lute configuration,
when being used in the determination of the absolute configuration of chiral secondary
alcohols.

Applied Chemistry: Evaluating the Non-Toxicity of Chemicals Used in Products
Gerhard Marini
University of Innsbruck, Austria
Chemicals used in products, such as cosmetics, toys, consumer electronics or
medical devices, have to be non-toxic. Different non-regulary frameworks may apply,
depending on product categoryas well as national or regular requirements. Still, the
general concepts of determining the toxicity profile of a chemical are universal. The
presentation will give an overview of the most-common biological effects of chemicals
and how these potential toxicity modes are investigated in the industry via in-silico, in-
vitro, and in-vivo models before the products put on the market.
SYNTHESIS OF CHITOSAN-BASED POLYELECTROLYTE COMPLEX AND ITS
ADSORPTION-DESORPTION STUDIES FOR SODIUM DODECYL SULFATE AND
HUMIC ACID

Department of Chemistry, Universitas Gadjah Mada
Sekip Utara, Yogyakarta, Indonesia
A series of polyelectrolyte complex films (PEC) had been prepared using chitosan
as polycationic polymer and pectin, alginate, κ-carrageenan as polyanionic polymers.
The PEC films were characterized using FTIR, SEM, swelling, and its stability in the acid-
base medium. The parameters used for sodium dodecyl sulfate (SDS) adsorption study
were the optimum composition of PEC film, contact time, pH of the medium, the initial
concentration of SDS, and its desorption ability. The FTIR spectra showed the typical
peak for the interaction of the polycationic and polyanionic polymer. The morphological
change of the surface of PEC films was observed before and after adsorption and
desorption. changed after used for SDS adsorption into the smoother one that was
analyzed with SEM. The swelling percentage of PEC films was observed to have a strong
correlation to the adsorption capacity. The PEC formation was found to be able to
stabilize the film at a wide range pH. For the three PEC films: chitosan/pectin;
chitosan/alginate and chitosan/carrageenan, the results showed that the composition of
PEC will generally be better at higher chitosan compositions (7:3 or 9:1). The SDS
adsorption was faster (120-180 minutes) than humic acid adsorption (480 minutes),
but both adsorbates tended to follow the pseudo-second-order kinetics and Freundlich
isotherm model. Adsorption of SDS and humic acid were optimum in the pH range of 5-
6. The desorption SDS from the three PEC films will be effective when using 0.1 M

Spin State Transition in Iron(II) complex
Kristian H. Sugiyarto
Iron(II) has been known to exist as high-spin (5T2) and low-spin (1A1) states. The first and the second states are due to the weak and strong ligand fields of the the corresponding complexes respectively. The magnetic moments of the two states are then immediately distinguished, being about 4.9-5.4 BM due to four unpaired electrons, but 0-0.6 BM due to no unpaired electrons in the corresponding electronic configuration of 3d6 system for the former and the latter respectively. It could be reasoanably understood that in the “mid” ligand field strength the magnetic moment may no longer reflect neither fully high-spin nor fully low-spin but to be in beetwen the two, and thus in this situation the concentration of the two fractions may be induced by temperature or pressure. Thus, the term spin-state transition or spin crossover in iron(II) or spin equilibium of 1A1 ↔ 5T2 are then introduced. Indeed many complexes of [FeN6]2+ were found to be temperature dependent associated with the spin-state transitin. In this paper, the iron(II) complexes of six N-coordinating agent of five-six membered rings and its character of magnetism, Mössbauer and UV-Vis electronic spectra as well as bond lengths are discussed. Key words: iron(II), spin-state, spin transition, Magnetic moment, Mössbauer.

because of interaction with silica active group. 3433.39 cm-1 absorption indicates the
vibration of O-H and vibration of N-H this shows the interaction of NH groups in silica
with OH groups on silica The absorption at wave numbers 1627.92 cm-1 and 1566.2 cm-
1 on chitosan-silica composite spectra showed typical absorption of chitosan ie the
amide band I and the amide II band The absorption at the 1095.57 cm-1 wave number
indicates the absorption of Si-O-Si vibration These results indicate the presence of
positively charged active groups that can interact with negative material outside the
microbial cell wall so that potentially inhibits the growth of bacteria

This study aims to determine the effect of combustion temperature and the
influence of copper(II) oxide concentration on ceramic glaze color. Electroplating liquid
waste contains copper(II) ions of 178.4510 ppm. Electrocoagulation method with
optimum conditions for copper(II) ions is used to produce colored coagulants of copper.
The results of the coagulant characterization with XRF showed copper(II) content of
(22.04 ± 0.73)%. The contents of other metals such as Cr, Cd, and Pb are below the
detection limit of the XRF device. Coagulant is a metal hydroxide which is dried and
calcined so that an oxide form is applied as a glaze ceramic dye. Based on the analysis of
homogeneity using chromameter, we obtained data that the L* value increased at the
combustion temperature of 999 and 1060 oC, but at a temperature of 1101 0C it
decreased. The value of a* decreases when the combustion temperature is raised.
Decreasing the L* value indicates the brightness on the surface of the ceramic glaze is
decreasing. Meanwhile, the decrease in a* value indicates a reduction of green color on
the ceramic glaze surface. The value of b* is directly proportional to the increase in the
temperature of ceramic glaze burning. Increasing the value of b* indicates an increasing
yellow color. L* and a* data also decreased in value when the metal oxide concentration
was increased, while the b* value increased at a concentration of 0.88 and 1.76%, but at
a concentration of 2.64 and 3.53% decreased.

particles were mixed with 5% HNO3 activator in batch system for 24 hours. Physical
activation conducted at 7000C and obtained 70.8% activated carbon. The
characteristics of activated carbon were compared to the carbon base by using
porosimeter, referencing to SNI 06-3730-1995 and finding the adsorption isotherm
patterns. Activated carbon surface area was 337.9 m2/g that classified as micro-pore
substance. In accordance to SNI requirements, the activated carbon fulfilled water
content, ash content and adsorption capacity of I2 while the study of adsorption
isotherm patterns showed that the activated carbon tend to follow Freundlich model for
all metal solutions of Cu, Cd, Fe, Zn respectively.

The aim of this study was to prepare and characterize a potential adsorbent
based on zeolite from Klaten, Central Java, Indonesia. The pre-treatment of natural
zeolite (ZA) consists of chemical activation using HCl (ZAA) and NaCl (ZAT). Cationic
surfactant benzalkonium chloride was used for modification of the zeolitic surface. ZA,
ZAA, ZAT, and modified zeolites were characterized by FTIR, XRD, and AAS. The cation
exchange capacity (CEC) of the natural zeolite measured by 1 M NH4OAc method.
Results show that the higher Si/Al ratio was achieved when natural zeolite was
activated by the strong acid of HCl, but acid activation did not change the structure of
the zeolite itself. The result of XRD analysis supports the AAS analysis result in which
the degrees of crystallinity of zeolite increased after acid activation. The studies by FTIR
and XRD analysis indicated that the zeolite structure remained unchanged after the
modification with the cationic surfactant. Thus the activated and modified zeolites
create a new material adsorbent to reduce pollutants in the environment.

Chalcone is an intermediate compound in flavanoid biosynthesis in nature. The
compound has a variety of interesting biological activities, including as an antioxidant and anticancer. Antioxidants are molecules that can retard or prevent the oxidation process or inhibit the formation of free radicals. p-Hydroxy-m-Methoxy-Chalcone (pHmMC) is a chalcone derivative which has anticancer activity in single and in combination use with Doxorubicin (DOX). DOX is one of chemoterapy agents widely used in cancer treatment but it has side effects of cardiotoxicity. This effect is generally associated with free radical formation. This study aims to examine the activity of pHmMC as an antioxidant both in single use and in combination with DOX. Activity tests as antioxidants were carried out by Chow method using DPPH (1,1-diphenyl-2- picrylhydrazyl). Butyl Hydroxy Toluent (BHT) and ascorbic acid (Vitamin C) were used as a positive control. Antioxidant activity is calculated as the value of 50% Inhibition Concentration (IC50). The results of the antioxidant activity test showed that the IC50 values of BHT, Vitamin C, pHmMC and DOX were 7, 3, 12 and 30 microgram/mL respectively. These results indicate that pHmMC has the potential as an antioxidant. The combination of pHmMC -DOX shows that pHmMC increase DOX antioxidant activity in combination use.

The use of cooking oil in various food preparations causes used cooking oil as
one of household waste. The content of free fatty acids in used cooking oil is very high,
so it can be used as raw material for non-food industries such as soap. This study aims
to produce soap using raw materials from cooking oil waste and NaOH. The waste used
is cooking oil which has been used 3, 5 and 7 times for frying, while the concentration of
NaOH used is 5, 10 and 15 grams dissolved in 27 ml of distilled water. The
characteristics of the soap products carried out by testing include: acidity, moisture
content, free fatty acid content and free alkali content in accordance with soap quality
standards SNI 06-3532-1994. The degree of acidity was analyzed by potentiometric
method, water content by thermogravimetric method, free fatty acid levels with
alkalimetry method and free alkali content by acidimetry method. The results of this
study indicate that cooking oil waste that has been used 3, 5, and 7 times can be used as
raw material for soap making using NaOH with a concentration of 5 to 10 grams / 27 ml.
The soap products have fulfilled the soap quality standards according to SNI 06-3532-
1994. Thus, cooking oil waste has the potential to provide benefits to the community in
overcoming one of the household wastes.

investigated by the mole ratio of Ni/Mn of precursors. Structural analysis of LiNixMn2-
xO4 was analyzed by x-ray diffraction equipped with U-Fit program package. It was
found that doping with Ni could change the size, crystallinity, and microstructure of
LiNixMn2-xO4. The LiNixMn2-xO4 solids have a cubic structure with a space group of Fd-
3m. Increased content of doping does not affect the structure. The average volume
LiNixMn2-xO4 is about 555 Å3 to 580 Å3. The crystallinity of the solids tends to increase
with the increase of Ni content. However, the increase of Ni content in the product
causes the unit cell lattice parameter decreases.

the poly 4-vinylpyridine (P4VP) as polymer backbone. However, aggreagation of MPc is
the challenge to overcome. The aim of this study to investigate the interaction
behaviour of cobalt(II) hexadecfluorophthalocyanine (CoPcF16) within poly 4-
inylpyridine (P4VP) using UV/Vis spectroscopy. Two solution of CoPcF16 and P4VP were
mixed and the interaction of CoPcF16-P4VP was observed through time using UV/Vis
spectroscopy at wavelength 500 to 750 nm. The results suggest that coordination of the
electrocatalysts is favoured by the presence of a high concentration of 4VP. Later, this
CoPcF16-P4VP electrocatalyst have a potential for water splitting or hydrogen
generation.

LiCrxMn2-xO4 (x=0; 0.02; 0.04; 0.06; 0.08; 0.1) have been successfully synthesized
by simple reflux-microwave irradiation technique. The structure of the product was
evaluated based on the mole ratio of Cr/Mn. The structural analysis of LiCrxMn2-xO4 was
analyzed by X-Ray Diffraction equipped with the U-Fit package program. It was found
that doping with Cr could change the size, crystallinity, and microstructure of LiCrxMn2-
xO4. The LiCrxMn2-xO4 solids have a cubic structure with the space group of Fd-3m. The
increase of the mole ratio does not affect the space group. The crystallinity of the solid
tends to decrease with the increase of Chromium. However, the increase of Cr content in
the products causes the increase in the lattice parameters of the unit cells and makes
the products’ volume size bigger, ranging from 540 A3 to 565 A3.

Oil and gas industry exploration activities produce produced water with a total
of up to millions of barrels per day. Produced water from oil fields has different
chemical compositions depending on geographic location, formation depth, oil
production methods, and age of oil production wells. Currently produced water is still
considered as industrial waste water containing heavy metals which are harmful to
humans and the environment, and require special treatment to be able to dispose of it
into the environment. To determine heavy metals content in oilfield produced water,
laboratory tests were performed for produced water from the Minas Area, Siak Regency,
Riau Province. Laboratory testing parameters include arsen, barium, boron, cadmium,
cobalt, chromium hexavalent, iron, copper, lead, manganese, selenium, mercury, and
zinc using instrument inductively couple plasma (ICP-OES) and LUMEX RA-915. Result
from laboratory tests show heavy metals content in produced water ranges between
<0,01 – 1,0 mg/L and only heavy metal of barium and boron which have a concentration
of more than 1.0 mg/l. Without advance treatment especially to eliminate heavy metals
content, produced water in Minas Area is harmful as source of drinking water and other
daily activity including for fisheri and crop plantation.

Eugenol (4-allyl-2-methoxyphenol) (A), the major secondary metabolite
extracted and isolated from clove (Syzygium aromaticum), has been normally used for
anesthetic in dentistry. In an attempt to increase biological activities of this easily access
natural compound, some new and known compounds were synthesized. Eugenol was
extracted and purified from cloves oil and further, its new and known derivatives (B-J)
were prepared through varies reactions and screened by in vitro model of antibacterial
activities using pathogen bacteria: Eschericia coli, Bacillus cereus, and Staphylococcus
aureus. Nearly all compounds showed antibacterial activities. The obtained results
demonstrate that eugenol (A) was still significantly more active than its analogues (B-J),
with inhibition (14-18) mm, suggesting that this chemical transformation failed to
increase antibacterial activities of eugenol. The presence of nitro (B), cyclic sulfonic
ester (C), N-dimethyl (D), quinoline (E), amino (F), isocyanate (G, H), amide and ester
(I,J) has no ability to enhance the antibacterial activities of eugenol.

The metabolic process that is in the body of living things, always involves various
solvents, both water and non-water. The human body mostly (more than 80%) consists
of liquid, so that the metabolic processes in the human body involve the interaction
between solvents and solutes in both ionic and compounds. The interaction between
solvents and solutes is known as hydration. While the interaction of dissolved
substances with water is known as hydration. Mercury is a transition metal element
located in group IIB period 6. Metal mercury is a toxic metal, can cause poisoning.
Chronic poisoning by mercury can occur due to shell contact, food, drink and breathing.
Chronic toxicity in the form of disorders of the digestive system and nervous system,
impaired lens of the eye and can cause damage to the fetal brain resulting in disability in
babies born. The hydration of mercury ions is observed by performing molecular
dynamics simulations of molecular mechanics. The base set used is DEF2-ECP for Hg
atoms, while for water molecules used dunning DZP base collection. Simulation is done
using potential partners and potential 3 bodies. The simulation is done by mixing 1 Hg2+
ion mixed with 499 H2O molecules. The simulation results in the form of trajectory data
are further processed to determine the structure and dynamics. Based on RDF analysis
shows that the average Hg and O (water) atoms are 2.22 A. Based on CND analysis, it is
known that the coordination numbers of hydration of Hg in water are as much as 6
molecules of water. Thus it is known that the hydration of Hg ions in water forms a
distorted octahedral molecule structure. Ligand (water) residence time in Hg based on
molecular dynamics analysis shows that hydration of Hg with water is stable.

Most of the students are having difficulties in writing the formula of chemical
compounds correctly. Hence, they are unable to write the balanced chemical equation.
Symbols in the chemical formula which are abstract lead the ‘early’ learners into
confusion and misunderstanding. Consequently, they fail to explore the knowledge of
chemistry. Thus, we propose the jigsaw puzzles as the visualizing tool to assist the
students in writing the chemical formula of ionic compounds. The objective of this
research is to test the effect of using jigsaw puzzles towards students’ understanding in
writing the chemical formulas of ionic compounds. This quasi-experimental design
research involves 115 science stream students from two secondary schools in Larut,
Matang and Selama district. Achievement test is used to measure students’
understanding in writing the chemical formula of ionic compounds. A survey is also
conducted on the experimental students’ perception on the activity using
questionnaires. Descriptive statistics (involving mean score and standard deviation)
and inferential statistics (involving t-test) are used to analyse the data, with the
assistance of the Statistical Package for Social Sciences (SPPS) software. The findings
proved that the jigsaw puzzles are effective in assisting students to write the chemical
formula of ionic compounds. Students also have a positive perception towards the
usage of jigsaw puzzles in teaching and learning activity. As conclusion, this jigsaw
puzzle activity should be implemented in teaching and learning to assist the students in
writing the chemical formula of ionic compounds. This study implies that the elements
of game should be infused during the planning of teaching and learning to ensure that
learning is more heuristic.

This article discusses the attitude of chemistry teachers towards the
development of chemistry teachers for inclusion classroom preparation program.
Inclusion program at the high school level are mandates that must be implemented to
provide equal educational opportunities for all humans being. However, high school
chemistry teacher candidates have not been prepared to teach chemistry in the
inclusion classroom. The study was conducted as exploratory research, that is,
preliminary research to dig deeper at existing problems to find solutions to be
implemented and designed later. In line with the goal, the research was conducted as a
survey technique for 65 high school chemistry teachers in Daerah Istimewa Yogyakarta
and Jawa Tengah Provinces who were selected by simple random sampling. The survey
was conducted using a questionnaire consisting of 14 questions divided into three
sections, namely cognition, affection, and behavior. The results show that the high
school chemistry teacher's attitude towards the development of the preparation
program for chemistry inclusion teachers is positive with an average questionnaire
score of 97.35

The study investigated the effect of using the 7-E learning cycle strategy in
teaching on the integrated ability and activity of eleventh graders in chemistry. To
achieve this goal, sixty two students were randomly selected then divided into two
groups- the experimental group which was taught by using the 7-E learning cycle, and
the control group which was taught by the ekspository method. Data were collected
using the following four instruments: a number of teaching situations which were
planned by 7-E learning cycle, integrated ability test, activity’s questionnaire and
activity’s observation. To answer the questions, manova was used. The results of the
study revealed that the students who learned using the 7-E learning cycle and the
ekspository method were not differently showed integrated ability and activity toward
chemistry learning at the 0.05 level of significance. The researcher recommends that
more studies should be conducted about the effect of this method on other instructional
variables.
