Penentuan Lokasi Titik Evakuasi Sementara Bencana Tsunami Menggunakan Metode Network Analyst (Studi Kasus: Pesisir Selatan Kabupaten Pangandaran)

Abstract

: A tsunami disaster is one of the most dangerous natural disasters and often occurs in Indonesia. Especially in the South Coastal area of Pangandaran Regency which has a history of tsunamis with a tsunami run-up height reaching 15.7 meters in 2006 based on data from BPBD Pangandaran Regency. According to the BMKG, the tsunami that occurred killed 664 people. As a disaster mitigation effort, this research analyzed the level of tsunami hazard and determined the location of Temporary Evacuation Places (TES) in the South Coastal Region of the Pangandaran Regency. The hazard level analysis was carried out based on slope data, roughness coefficient, tsunami run-up height, and coastline. Then from the results of the analysis of the hazard level are used to determine the location of TES using the Network Analyst method. The basis for making the distribution of TES locations is by using Service Area analysis based on pre-existing TES distribution locations from BPBD Pangandaran Regency. From this analysis, the distribution of TES locations and coverage areas will be identified. If the Service Area coverage of the distribution of TES locations from BPBD Pangandaran Regency does not cover the entire tsunami-affected area, then additional TES points will be made. This study resulted in 55 TES location points that can be used as evacuation sites with
