    Abstract

    Cikalong Subdistrict, located in Tasikmalaya Regency, is one of the southern coastal areas of West Java that has a high level of tsunami hazard. This condition is due to its geographical proximity to the active subduction zone of the Indo-Australian and Eurasian Plates in the Indian Ocean, as well as the dense settlements along the coast and limited mitigation infrastructure. This study aims to map tsunami hazard levels and evacuation routes using a Geographic Information System (GIS)-based approach, in order to enhance the effectiveness of disaster mitigation and community preparedness. The tsunami hazard mapping method involves scoring, weighting, and overlay analysis of four main parameters: elevation, slope, distance from the coastline, and distance from rivers. Meanwhile, evacuation route analysis employs the Network Analyst method to determine the fastest and safest routes to evacuation shelters. The results show that Cikalong Subdistrict can be classified into three tsunami hazard zones: low, medium, and high, with safe zones located at elevations above 20 meters above sea level. In addition, six coastal villages were analyzed to determine optimal shelter locations and evacuation routes based on technical parameters and accessibility criteria. Validation of the mapping results using the Confusion Matrix method indicates a high level of accuracy. This research produces tsunami hazard and evacuation route maps that can serve as references for disaster mitigation efforts by local governments, communities, and other stakeholders. Thus, the GIS-based approach proves to be effective in supporting targeted, responsive, and sustainable disaster planning in coastal areas with high tsunami hazard levels
