This research has been conducted in Anduna Village Road Section, Laeya Sub-district, South Konawe Regency, Southeast Sulawesi Province which aims to determine the subsurface structure based on resistivity values and provide a 2D cross-section of the subsurface that has the potential as a sliding field in the research area. The method used is resistivity geoelectric method. Geoelectric measurements were carried out as many as 3 passes using the Wenner-Schulemberger configuration. With the length of tracks 1, 2, and 3 each 150 meters. Geoelectric data processing is carried out using Res2Dinv software so as to obtain a 2D cross section to determine the potential for sliding fields. Based on the analysis of the rock resistivity value of the study area, the surface that has the potential for sliding fields on track 1 is at a depth of 1.25 - 28.7 meters with a resistivity value of 6.76 - 713 Ωm. On track 2 is at a depth of 19.8 meters with a resistivity value of 736 - 845 Ωm for the cross section of track 3 resistivity value of 38.0 - 236 Ωm the boundary of this sliding field is at a depth of 19.8 meters.
