Abstract
The general prevalence of landslides and mass wasting in West Java region shows interrelation to heavy weathering and slope condition. Alerting issue of geological hazard should be considered and inspected thoroughly by the researchers because of the danger it holds with human lives and infrastructure losses. This research was conducted in the administrative area of Sukarasa and the surrounding vicinity, Tanjungsari District, Bogor Regency, West Java, Indonesia. Three methods were used in the research, i.e; (1) Geological map and slope steepness, (2) Morphometry analysis, (3) GIS data using LiDAR satellite images. Area consisted of lithological properties, i.e; (1) Claystone, (2) Volcanic intrusion. Morphometry analysis includes the supporting aspects such as; morphography or morphogenetic that later will be applied for quantitative evaluation in landform. It also gives direct separation in dividing the research area with two classes of weathering and erosion, i.e; high, medium, and low level. Integrating the results with each method rendered, should give insight into final outcome in mapping landslide potential. Therefore, based on Landslide Risk Potential Map, it can be concluded as a percentage which resides of high risk by 60%, 30% medium risk, and 10% low risk of the total area of the research.
