Abstract. Mamasa Regency in West Sulawesi Province, particularly Tabulahan District, is known for its susceptibility to landslides, with significant impacts on local communities. This study aims to analyze the landslide risk level in Tabulahan District and develop appropriate mitigation measures. The methodology includes analyzing basic physical aspects, spatial analysis using Geographic Information System (GIS) with overlay and scoring approaches, and descriptive analysis to understand the actual conditions on the ground.
The study results indicate that the landslide risk levels in Tabulahan District vary, with areas categorized as low, moderate, and high risk. Key factors determining landslide susceptibility include slope steepness, rainfall, soil type, land use, and geological conditions. Additionally, physical, demographic, social, economic, and environmental vulnerabilities contribute to increased risk. The capacity to handle disasters also varies, with some villages having better access to health facilities and disaster preparedness compared to others.
The mitigation recommendations from this study include both structural and non-structural measures, such as improvements in land use planning, enhanced community capacity, and the implementation of slope stabilization technologies. This research is expected to serve as a basis for local government in formulating more effective landslide mitigation policies in Tabulahan District.
