Groundwater constitutes a significant component of the Earth's hydrological cycle, serving as a vital source of potable water for humans. It plays a role in contributing to the flow of surface streams that ultimately discharge into the seas within the hydrological cycle. An aquifer represents a portion of groundwater characterized by its ability to transmit water due to its permeable geological formations. The Time Domain Electromagnetic (TDEM) method is among the geophysical investigation techniques employed to leverage electromagnetic field induction within subsurface media containing groundwater. This method is particularly well-suited for mapping groundwater levels as it can generate resistivity-depth structures that correlate with the Earth's surface geological conditions. In this final project, data measurements will be conducted using the WTEM-3Q, which is a central loop TDEM instrument, within the ITB Ganesha campus in West and East Park. Data processing will utilize ZONDTEM1D software to create a 1D model of subsurface layers. Analysis of the data from the five measurement points reveals the presence of three distinct rock layers, with groundwater depths ranging between 14 – 16 meters below the surface.
