| Summary: | Pangandaran Tourism Area is a strategic area that supports various economic and social activities. However, this strategic area's existence is threatened by potential tsunami disasters, primarily from megathrust earthquakes along the South Coast of Java Island. Given the potential tsunami disaster, it is necessary to reduce the risk of disasters. One of the efforts to reduce the risk of disaster is conduct evacuation plan and drill. In order to run effectively, an evacuation plan is needed. In making an evacuation plan, information is needed regarding the behavior of refugees in carrying out evacuations, evacuation times, and appropriate evacuation sites in the Pangandaran Tourism Area. Therefore, in this study, questionnaires were distributed to to identify people's behaviour in carrying out evacuations and the tsunami evacuation model was developed to obtain comprehensive information as the basis for evacuation planning. The results of the questionnaire show that there are residents who choose to evacuate after seeing the incoming waves. In addition, the majority of residents choose to use motorized vehicles which can cause congestion during evacuation. The results of this evacuation modeling show that all agents can reach the evacuation site before the first wave comes if at the time of feeling the earthquake the whole community immediately evacuates. However, if the start time of community evacuation is different, where there are people who just evacuate after the waves come then the travel time needed by the community to reach the evacuation site is more than 60 minutes. From the simulation results it is also known that the travel time to go to 9 TES (3 main TES and 6 alternative TES) is faster than the travel time to the 3 main TES only. Therefore, the use of alternative TES is one option that can be done to reduce the risk of fatalities due to the tsunami disaster. |
