Abstract

The research location is in the Puspahiang area, Tasikmal aya Regency, West Java, where most of the Tasikmalaya area consists of moderate plains with an altitude of 250 to 750 meters, and the level of vulnerability to ground movement is quite high (BPS Tasikmalaya 2021). Observations in the research area were carried out by taking soil samples for testing the type of soil that occurred at the landslide location, including water content analysis, specific gravity analysis, atterberg analysis and sieve analysis and remote sensing analysis was carried out to determine the level of vulnerability to landslides based on several parameters. from Relief Diversity, including bifurcation index, ruggedness index, basin relief, relief ratio, dissection index, relative relief, slope in degree, lineament density, and Normalized Difference Vegetation Index (NDVI) parameters. The results of this study explain that the research area has 5 levels of landslide susceptibility including very low (very low), low (low), moderate (moderate) high (High), very high (Very High). From these observations these results become a reference in providing recommendations for mitigation of the research area.
