Abstract

Water is important for mankind. The groundwater exploration is conducted to determine the potential shallow fresh water. The purpose is to provide the water supply especially for local people of Kedungadem city in Bojonegoro district of East Java, Indonesia. The local people of Bojonegoro had faced the insufficient water supply to support daily living, hence Kedungadem city is selected to investigate the potential groundwater. The common geophysical methods used to study the groundwater potential is 2D resistivity and remote sensing. The study area is focused on Kedungadem city of Bojonegoro, where the selected resistivity sites are Bunten, Tondumulo and Lele. The configuration setting for 2D resistivity method is pole-dipole array, while for remote sensing, the satellite imagery used is Landsat 8. The potential groundwater zone is defined by performing the weighted overlay analysis. The integration of both methods indicates the high potential of groundwater occurrence in Tondumulo and Lele, and as for Bunten the potential of groundwater is low.
