Abstract

The need for water for agricultural irrigation sources and the water home industry in the Krawangsari area can be a source of conflict in the future if it is not immediately addressed. Gradual studies are needed to maintain the continuity of groundwater resources and the equal distribution of utilization, one of which is to map groundwater aquifers. This study aims to determine the potential of groundwater resources using geoelectric resistivity methods with vertical electrical sounding (VES) and horizontal profiling techniques (2D mapping). The inversion results of vertical electrical sounding (VES) show variations in depth and thickness of shallow aquifers with groundwater resistivity values in sedimentary rocks ranging from 1 - 100 Ωm and in igneous rocks between 0.5 - 150 Ωm. The results of 2D Resistivity Mapping show that aquifer characteristics in the eastern part of Krawang Hill have a depth of 1-3 m for shallow aquifers with a thickness of aquifers between 15 m and more than 70 m. The depth of the bedrock ranges from 50 - 150 m with a pattern deeper into the west. While for aquifers in the southern part it has a characteristic depth between 2-5 m for shallow aquifers with a thickness of aquifers ranging from 25 - 50 m and the depth of the bedrock between 20 - 70 m. The potential of groundwater aquifers in the agricultural environment is in the western region of Krawang Hill so the development of irrigation wells for agriculture should be carried out in the western part. Keywords— Aquifer, VES, Resistivity, Krawangsari.
