Groundwater estimation based on resistivity values ??in oil palm plantations has been successfully carried out. The method used for this estimation is the Wenner-Schlumberger configuration geoelectric method. The number of lines used is two lines with a length of 195 meters each. From the inversion results, the resistivity values ??of lines L1 and L2 are 10.3-607 ?m. From these resistivity values, the soil layers in both paths are suspected of sand, clay sand, and granodiorite weathering. The sand layer is alleged to be an aquifer layer containing groundwater with a resistivity value of 10.3-33.2 ?m. This groundwater is suspected to be at a depth of 1.25-39.4 m for line L1, while in line L2, it is at a depth of 3-24 m. The flow of groundwater follows the topography of each line. The information related to this groundwater can be used for oil palm development or as an alternative to drilled wells.
