Determining location of tsunami disaster temporary evacuation shelter (TES) utilizes network analysis in City of Makassar, South Sulawesi Province

The city of Makassar is a vulnerable area of the tsunami because it is located on the southwest coast of Sulawesi Island. The population is the highest number on Sulawesi Island. People will cause a lot of losses in the event of a tsunami in Makassar City. Therefore, preventive measures are needed as disaster mitigation. One of them is to determine the location of the Temporary Evacuation Place (TES) in the tsunami-affected area. The purpose of this study is to determine the location of TES on the coast of Makassar City. The variables used are DEM, land use, and travel time. TES locations are determined using GIS, the network analysis method with the tool service area. The analysis used was to sort outbuildings in tsunami-affected regions based on the size and height of buildings according to the standards of the Federation Emergency Management Agency (FEMA). Based on the results of the research, there are 14 TES that are distributed in Makassar City. TES is in densely populated residential areas affected by the tsunami with an average height of 0-5 m above sea level. The TES in Makassar City is in the form of mosques, auditoriums, schools, and factories.
