Abstract

Based on data from the National Disaster Management Agency (BNPB), Gunuang Malintang Village, Limapuluh Kota Regency, West Sumatra Province is one of the areas experiencing the impact of landslides due to various triggering factors. Therefore, it is important to map the vulnerability of landslides and analyze the level of vulnerability using the fuzzy logic method in order to reduce the impact of hazards from landslides in the research area. This study uses an intelligent system based on fuzzy logic, by taking a quantitative approach to each fuzzy set or parameter through simple computation. The parameters used are based on the study of literature, the conditions of the research site and available data sources, among others; (1) Slope (2) Rainfall (3) Elevation (4) Lithological Type (5) Soil Type (6) Land Use. The analysis process with ArcGIS 10.3 software resulted in three classes of landslide susceptibility in the research area, namely low hazard value < 4.50 with an area of 25.5 km2 or about 31% of the research area, moderate vulnerability with a value of 4.50-5.40 dominates the research area as much as 52% or an area of 42.8 km2 and high vulnerability with a value > 5.40 covering an area of 12.7 km2 or 12.7%.
