Preface
Distinguished guests and workshop participants,
It is a great honor to Tsunami and Disaster Research Center (TDMRC) of Syiah Kuala
University to host the 5th
Annual International Workshop and Expo on Sumatera Tsunami
Disaster Recovery (AIWEST-DR). This event would be a forum for all disaster practitioners
and scientists to deliver their ideas and experiences to save lives and environment from any
disaster. Learning from five consecutive events of AIWEST-DR, the TDMRC, once again,
invites all parties to sit together in this event, bringing positive measures and ideas to reduce
the risk of disaster.
The world has encountered serious changes in terms of disaster frequency trends and number
of casualties at every disaster event. The reflection is a stark proof found in recent
Indonesia’s problems with Merapi volcano, Mentawai Tsunami, and recent Wasior flood
disasters. Numbers of losses are mounted and the time is extremely limited. It is duty of all of
us to be immediately and to be properly offer solutions for reducing the losses. Therefore, the
AIWEST-DR is expected deliberately to discuss the problems and the solutions.
It is hoped that this workshop will stimulate further efforts that result in better disaster
management strategies and will yield initiatives toward sustaining the learning and
knowledge sharing processes, integrating the international lessons, and providing a sound
platform for a sustainable international collaboration in Disaster Risk Reduction (DRR), with
a particular reference to tsunami-related issues, all of which will hopefully help establish
disaster-resilient communities.
We are also pleased to inform this forum that more than 73 technical papers from 13
countries are going to be disseminated in this year workshop. In addition, various important
and interesting issues related to disaster risk reduction (DRR) and research on Tsunami will
be discussed in two panel sessions.
On behalf of the TDMRC, I would like to express our sincere appreciation to the Government
of Aceh, Multi Donor Thrust Funds (MDTF), and UNDP, for the support and good
cooperation afforded to us leading to the proper organization of this workshop. Special thanks
are also extended to our fellow national and international counterparts for their collaborations
and continuous support in this effort.
Please enjoy and have a fruitful workshop!
Thank you.

Abstract - Landslide is type of natural disaster which may
cause huge losses of live and properties. Many landslides
triggering factors found in Kaligesing make this zone as
landslide prone area in Indonesia. Zoning hazard area was a
solution to assess landslide disaster since there is still a great
danger of further landslides in the region and also it is strongly
linked with spatial issues. The combination of GIS and
Analytic Hierarchy Process (AHP) are used to create landslide
hazard zone in this study. Factors, such as landform, land
utilization, slope steepness, soil texture and lithology are
considered for use in AHP through pair-wise matrix. The
output of calculation was validated with present landslide
location. Based on the judgment matrix and calculation, the
result showed ë max = 5.406256, the feature vector of
normalization: F= 0.4042,,,,0.2746,,,,0.2018,,,,0.0845,,,,0.0349).
In this calculation, RI =1.12. According to relational formula,
CI=0.101564. A consistency ratio (CR) was computed to verify
that the consistency of matrix. CR value of 0.090682, meant
that the pair-wise matrix is consistent (threshold CR<0.10) and
can be used for assigning the criteria weight. Spatial
distribution of the susceptibility classes of landslide in
Kaligesing showed that more than 40% of the study area was
categorized as landslide prone area with moderate
susceptibility and 30.05% falling on high susceptibility class,
while the rest 20.78% was categorized as less susceptibility
class.

I. INTRODUCTION
Currently around 70 percent the world’s population lives
are affected by natural disaster, such as earthquake, flood
and landslide [1]. During 1991-2005, EMDAT reported
total amount of economic lost due to natural disaster as
379.15 US $ billion in developing countries [2]. Comparing
with other part of continent, Asia is the world’s most
disaster prone region. Geological disasters like landslide
hold second position in number of occurrences after Hydro-
meteorological disaster. Several studies showed that
disasters are likely to occur due to their environmental,
climatic and geographical condition. In particular, landslide
will occur in more intensive scale in countries which has
mountain geographic characteristic area.
Landslide is a natural disaster which may cause huge
losses of lives and property. The occurrence of landslide is
influenced by many factors, naturally occurring or by
human activities. Natural landslide may occur by collapses.
It is triggered by physical condition such as topography,
climate, vegetation, land use and earthquake. It is also
commonly occurred due to over human exploitation, such as
forest logging, over grazing, etc. Moreover, landslide often
occurs in mountainous area which has low stability slope.
Many landslide triggering factors are found in Indonesia
that makes Indonesia as the second highest number of
landslide in the world [3]. According to [4] there are 20
regions in Daerah Istimewa Yogyakarta (DIY) province -
Central Java province and 29 regions in East Java province
which are categorized as susceptible to landslide hazards.
All of the areas were witnessed mass movement and rock
movement. As it is mentioned by [5], most of the hilly areas
in Java are susceptible to landslide. The landslides in Java
Island increase over time [6]. The occurrences of landslide
during 1990 and 2005 caused the death of 1,000 people. The
highest loss was incurred in 2005 that victimized 118
individuals. Furthermore, data showed by [7] the extreme
event was in January 2006 causing death of 142 people and
damaging 182 houses; and landslide in September 2000 in
Purworejo caused death of 44 people and 20 people were
injured as well as 77 houses were damaged [8]
Kaligesing, sub-district in Central Java Province,
Indonesia, is known as one of the landslide prone area [9].
Most part area of Kaligesing sub-district is upland area
which varies in lithology, geomorphology and hydrology.
Due to these factors, this area is susceptible to landslide
hazards. More than 10 occasion of landsli
[10]. Generally, three cases of landslide occur in each year
[11]. The degree of damage was different at different areas
on houses and road network. The average indemnification
was about 1,000,000-100,000,000 IDR for eac
Management of land resources is very important due to
the susceptibility of this area. In order to curb and reduce
the impacts of landslide also to be more effective to
exploitation the land, landslide hazard zoning can be one of
the solutions. Combination of GIS and AHP are the
effective method for hazard assessment, GIS has powerful
for spatial analysis while AHP has certain advantages in
multi-index integrated evaluation.

A. Description of study area
The research area is located in Kaligesing sub
Purworejo Regency, Central Java Province Indonesia
(Fig.1). It lies between South Latitude 7º 50’ 34”
45” and East Longitude 110º 07’ 46”
Kaligesing sub-district has 21 villages, namely: Village
Somongari, Jati Rejo, Dono Rejo, Hulosobo, Kali Harjo,
Tlogoguwo, Kali Gono, Jelok, Kedung Gubah, Purbo
Wono, Pandan Rejo, Ngaran, Tawang Sari, Gunung Wangi,
Tlogo Rejo, Sudogoro, Tlogo Bulu, Hardi Mulyo,
Sumowono, Pucung Roto, and Ngardi Rejo. The total a
of the study area is approximately 7,472.89 ha with total
population 35,895 citizens. Kaligesing sub
between Purworejo City and Yogyakarta Province. Due to
improvement of roads network, the development process in
this area has increased particularly along the roads.
Kaligesing sub district is an important region for socio
economic development particularly fruit production in
Purworejo district Central Java province Indonesia.
Unfortunately, Kaligesing is a landslide prone area. This
study area represents characteristic feature of most of
upland area in Central Java, Indonesia.
The climate of the study area is mostly sub
condition. Based on Oldeman classification, Kaligesing sub
district is categorized as C3 class climate. I
rainfall intensity, 200 mm in wet month and 100 mm in dry
month. The average amount of rainfall in study area is about
2000 to 5000 mm in a year. Based on Oldeman
classification, wet condition prevails in Kaligesing
months and there is dry condition for 2

III. RESULTS AND DISCUSSIONS
Due to of several impacts of landslide, this study develop
landslide hazard map for learning about potential local
landslide hazard and taking step to reduce those hazard.
The basic assumption which used in this study is the geo-
morphological concept that said “the past and present are
the keys to the future [17]. This principle can simply explain
through basic concept of landslide. Landslide is typically
occurred periodically lies on specific physical condition in
certain area like geologic, slope and soil condition which
categorizes as indelible factors. Landslide that occurred in
the past can be occurring in the future under similar
condition. Thus, take similar factor as consideration
composing landslide hazard susceptibility is an idea in this
research. Further, to achieve appropriate landslide hazard
map, this research also combining to other factor like land
use. Factor overlay method and analytic hierarchy
processing (AHP) were used to develop landslide
susceptibility map. Slope class, soil texture, land use,
lithology, and landform are factor that considered
composing the map. Reference [18] conducted a study
based on a research report from [19] and found five classes
of landslide hazard. This research modified the finding and
divided land slide hazard parameters of the respective study
area into three classes based on the findings of [18]; high
susceptible, moderate susceptible and less susceptible. The
selected factors and its score are revealed in Table 4.
AHP was used to determine degree of important for each
factor related to the landslide occurrence. The relative
importance of criteria among one and another was assigned using pair wise method. The pair wise comparison for each
Variable was justified in discussion with an expert and data
from local people perception as well as site visit. As result
of discussion with expert, rainfall factor that mentioned by
local people as factor causing landslide disaster in study
area cannot used to be considering factor due to rainfall data
coverage area. The coverage area is too small and the
pattern of rainfall is homogenous. In addition, in case of
Indonesia, the lowest level of rainfall station is placed
insub-district level. Hence, it should be improve with

develop own rainfall station by researcher to get appropriate
data. Further, main idea for composing landslide hazard
mapping is to reduce hazard its self. Thus, this research tried
to considered most factor that can be managed or control by
human being. According to degree of importance slope was
the most importance factor comparing with landform,
lithology, land use and soil texture. Table 5, 6 and 7 from
analysis are revealed the processes of AHP justification.
Based on the judgment matrix and to calculate, λ max =
5.406256, the feature vector of normalization: F=
(0.4042,0.2746,0.2018,0.0845,0.0349). In this
calculation, RI = 1.12. According to relational formula,
CI=0.101564. A consistency ratio (CR) was computed to
verify that the matrix is consistent. CR value is 0.090682,
meaning that the pair-wise matrix is consistent (threshold
CR<0.10) and can be used for assigning the criteria weight.
