It has investigated the subsurface environment on the area of Cibubur Region, West Java Province by using the geoelectric method. This research aims to identify the type of rock layers and ground water based on resistivity values then determine the depth and thickness of aquifers in the study area. This research was conducted using the method of resistivity sounding consisting of five track and measurement configurations using Schlumberger configuration with each path length of 140 m and 10 m spacing between tracks. The results obtained from this research that subsurface at every track location of the research has 7 layers of rock that dominated the ground silt containing sand that has resistivity values ranging from 61.48 Ωm 113.16 Ωm bedrock filled with dry soil which has a resistivity value of 316.84 Ωm 449.10 Ωm, soil damp soft silt that has a value of resistivity 9.30 – 13.48 Ωm and bekekar rocks that have resistivity value of 227.26 254.04 Ωm. The existence of the aquifer in the study sites are located on each track and are at a depth of ± 20 m to the deepest ± 70 m with a thickness as 50 m which has resistivity values ranging from 20.21 Ωm 81.6 Ωm. This shows that the location of the study had sufficient layer of soil can store water and groundwater passed pretty well.
