Abstract

Identification of landslides in the Gumay Talang Area, Lahat Regency, South Sumatra has been carried out by analysis using the Geographic Information System (GIS) method. Based on the National Disaster Management Agency (BNPB) in the study area, the population index class exposed to landslides was moderate. From field observations, there are six observation points for landslides which have low hill morphology - hills. There are eight parameters used, namely elevation, slope, rock type, rock type, land cover, rainfall, linement density, and NDVI to identify landslides. From these parameters, an overlay was performed on the ArcGis software, so that a landslide hazard map was obtained which had a low class landslide vulnerability level (green) with an area percentage of 5%, medium (yellow) area percentage of 25%, and high (red) area percentage of 70 %. Landslide vulnerability is dominated by high class with a percentage of 70% of the study area. Keywords: Overlay, Landslide, Parameter, Geographic Information System
