Abstract
Sangubanyu sub-vilage is administratively located in Banyuwangi Village, Bandongan Subdistrict, Magelang Regency. During the dry season, it is common to find dry wells in the community, making it difficult for residents to access clean water. This situation is highly ironic, as Magelang Regency generally experiences high rainfall, is situated in the Progo and Bogowonto river basins, and is surrounded by mountains that, theoretically, act as water catchment areas. The investigation of aquifer depth was conducted using the Vertical Electrical Sounding (VES) method with a Schlumberger electrode configuration, which is used to map the vertical distribution of subsurface resistivity. VES field data collection was carried out at two measurement points using two current electrodes and two potential electrodes. The electrode spread at each measurement point was 400 meters. The sounding data from each measurement point was interpreted using IP2win software version 3.01, and the results were presented as resistivity logs showing resistivity values, depths, and the thickness of each layer. The interpretation results yielded a 1D resistivity model, showing variations in resistivity with depth. The aquifer layer was identified as sandy tuff with resistivity values ranging from 17 Ωm to 21 Ωm at depths of approximately 33 to 78 meters.
