Abstract.The most significant measure in reducing tsunami disaster is an early evacuation. The aim of this study is to developments a dynamic evacuation model with using simulation of Agent-Based Modeling and Simulation (ABMS). The Shelter Plan Analysis is also conducted in this study to establish applicable evacuation places. All analysis in this study based on a geographic information system (GIS) data such as shelter location, evacuation networks, housing and other information. The shelter plan analysis is the methods to evaluate an applicable shelter. The important variable in this analysis is nearest accessibility based on the existing road from the residential area to the evacuation building. In order to set input data for this analysis, we conducted a questionnaire survey to the local people in Pacitan, which is a typical populated coastal city in Indonesia, located in East Java province. The agent-based model is according to multi criteria decision making (MCDM) for internal and external factor. The concept of MCDM was used to develop a weighted suitability decision matrix in a simulation's model. We also conducted the field survey in this city, especially focused on the condition of evacuation shelters and evacuation networks, in order to evaluate the shelter plan on GIS as well as to conduct the simulation of the agent-based model.

Studentification occurs in a college town so that the large number and activity of students and those related to universities affect the condition of the city. The impact of students consists of socio-cultural and economic changes that can be seen in physical changes. In the previous research, these changes often result in conflicts between students and residents, less service for residents, and a worsening physical environment. This study aims to find the contributions of the studentification model in Malang city as one of the college towns in Indonesia that occurs in the area adjacent to the campus Brawijaya University Malang City. The method used in this research is Structural Equation Model Partial Least Square. Data were taken through in-depth interviews and online surveys to 32 neighbourhood leaders as respondents. Some of the findings show additional thought contributions to studentification theory, namely: community sustainability and environmental quality improvement.

The border area between Indonesia and Papua New Guinea (PNG) is mostly defined based on geographic coordinates without considering cultural boundaries, which has resulted in high intensity of interaction and trans-border movements in the area. Trans-border movements in the border area of Indonesia and PNG, specifically in Pegunungan Bintang Regency border area, are classified as illegal movements. This is due to lack of border area facilities to accommodate these movements. There are varieties of purposes of trans-border movements in this area, which are classified into 4 categories. They are economic purposes, cultural purposes, social purposes, and political purposes. Circular or temporary movement is a trans-border movement category based on the maximum of 6 months of stay in the destination country. There are three factors that influence the borderlanders on conducting trans-border movements, namely individual characteristics factors, social-economy factors, and cultural factors. The movements are mostly conducted for economic purposes in addition to the influence of individual characteristics factors.

Sempu Island is one of the marine conservation areas, which has an important function in the conservation stage, namely preservation, preservation itself means the preservation of biodiversity and protected areas in biotic and abiotic life support systems. Many problems arise on Sempu Island as a protected area due to lack of access, which triggers a conflict of interest in the management of the area between policy makers and the community. Water quality is an important parameter for assessing water conditions and productivity associated with other biotic parameters, such as plankton and zooxanthellae. The method used in this research is quantitative method with direct in-situ data collection using water quality parameters measuring instrument AAQ Rinko 1183. Data collection was carried out at 15 station points in the Sempu Strait. The results obtained show that the average temperature in the Sempu Strait waters is 26.27 °C, turbidity is 0.40 ftu, salinity levels are 34.57 ppt, pH levels are 8.6, DO levels are 6.656074 mg / L, and chlorophyll content of 1.17 mg / m 3. This research is the result of preliminary research from the advanced research stage, which discusses the resilience of the Sempu Island aquatic ecosystem.

Local wisdoms such as a traditional ethics, land-use system and others had sometimes mitigated tsunami damages in Indonesia. The effective use of those local wisdoms is strongly desired especially in developing countries, because it is quite difficult for those countries to allocate enough budgets for constructing hard type of countermeasures against tsunami. Among local wisdoms against tsunami hazard, this study evaluates the efficiency of a hollow topography which can be seen on the beach along Lampon village in Indonesia. Artificial hollows are arrayed on the beach as one of the local wisdoms in Lampon village to reduce the intensity of inundated tsunami flow. The numerical simulation of tsunami inundation is conducted to evaluate the efficiency of this hollow topography. Furthermore, this study evaluates the efficiency of some contrivances, such a combination of vegetation area and a multiple-use of hollow and embankment topography, in order to enhance the performance of countermeasure based on the local wisdom.
