In the rapid development of big cities like Bandung, a problem arises, namely land subsidence, In some areas in Bandung, Gedebage si one of them. Significant and very rapid land subsidence can have fatal consequences for the construction or buildings on it such as roads, houses, factories, and so on. The research area has an area of 139.22 Ha and this research is supported by the presence of 2 borehole data around the study area, each of which is 60 meters deep. In this study, we will discuss the causes of land subsidence in the Gedebage area, Bandung, West Java by observing the subsurface geology. In this study, subsurface modeling will be modeled using the type resistivity method. Wenner Array for 2-dimensional modeling and Schlumberger Array for 1-dimensional modeling with deeper penetration. In conducting the modeling, IPI2Win software was used for 1-dimensional modeling and RES2DinV to model 2 dimensions.
