The Sentinel-1 product can be built into a Synthetic Aperture Radar (SAR) capable of providing terrain data that can be built into landslide mapping parameters. Landslide becomes a disaster if there are affected areas, one of which is an agricultural area, so mapping the landslide hazard in agricultural areas is very important to study. The purpose of this study is to utilize Sentinel-1 products in mapping landslide hazards in agricultural areas in Sumedang Regency. The parameters used are the slope of the SAR data, geological conditions, soil conditions and meteorological conditions. The method used is the overlay intersect technique in which each weight and parameter score refers to the INARISK guidelines of the National Disaster Management Agency. Based on the analysis of the landslide area in Sumedang Regency, it tends to spread in the Southern Region. This area is a complex of hills with steep slopes, old volcanic parent rock which is quite brittle, high rainfall, clay soil texture, and the largest area of lineaments. The biggest proportion of landslide hazard lies in dry land agriculture with a percentage of 75.75%. Sentinel-1 can be an alternative to landslide mapping by building a SAR product into several slope parameters. © The Authors, published by EDP Sciences.
