| description | This study aims to determine the subsurface structure in landslide-prone areas and to identify the potential for landslides in Subo Village, Pakusari Subdistrict, Jember. The survey was carried out using the resistivity geoelectrical method with Wenner-Schlumberger configuration and 2 m electrode spacing. Four trajectories of different lengths were used, namely 50 m for Trajectory 1, 30 m for Trajectories 2 and 3, and 26 m for Trajectory 4. The data obtained are the magnitude of the potential difference (V) and the magnitude of the current (I), then processed using Res2dinv software to obtain a 2D section and Voxler to obtain a 3D section. It was found that the subsurface structure consists of clay layer with resistivity of 1,48-37,9 ?m, the next layer is sand layer with resistivity of 8,53-192 ?m and sandstone layer which is quite dominant in Tracks 1 and 4 with resistivity value > 432 ?m. The results of landslide potential identification with 3 indicators were also obtained. It can be concluded that Subo Village, Pakusari Subdistrict, Jember is composed of clay, sand and sandstone layers and has a high landslide potential. |
