The source of underground water is located in an aquifer layer, which is a layer with rocks that have cavities capable of allowing water to pass through and also have the ability to store water due to the impermeable nature of the rocks below the aquifer layer. Aquifer estimation can be done using several geophysical methods, one of which is the geoelectric resistivity method that utilizes the physical characteristics of a material, namely specific resistance or resistivity. Geoelectric methods can be divided into several classifications, namely modeling dimensions and configurations used. In this study, the Wenner-Schlumberger geoelectric method with 1-D and 2-D modeling configurations was used. The interpretation results obtained from field measurements in the rice field of Rancaekek, Bandung Regency, West Java, indicate the presence of a suspected closed-type aquifer formed by types of rocks such as tuffaceous claystone, tuffaceous sandstone, sandstone, and tuffaceous gravel. The aquifer found is known to have its upper boundary at a depth of approximately 14 meters below the ground surface.
