Open dumping activities at the Batu Layang TPA can potentially cause leachate pollution to the environment. Leachate that seeps into the ground can contaminate groundwater. Most people around the Batu Layang TPA use groundwater for MCK (bath, wash, toilet) purposes. If the groundwater is contaminated with leachate and used sustainably by the community, it will impact health problems. Therefore, it is necessary to manage the distribution of leachate. One of the leachate management systems is modeling the potential distribution of leachate below the soil surface. The purpose of this research is to analyze the distribution of subsurface leachate around the Batu Layang landfill area based on the resistivity value. They are modeling the potential distribution of leachate below the ground surface in this study using the Wenner configuration geoelectric method. Processing of geoelectrical measurement data using Res2DInv software so that the potential distribution of leachate under the soil surface is obtained in 2 Dimensional forms. The result of this research is the resistivity value
