Abstract

Groundwater is water that occurs naturally in the subsurface, and is contained in the aquifer. Groundwater is the water source of the most widely used by the public for purposes of clean water. To determine the condition of the aquifer configuration one of the methods that can be used is the 2D electrical resistivity. Exploration drilling is one effective way to determine directly the presence of groundwater, but to determine the location of the drilling necessary geophysical approach to describe subsurface conditions prior to drilling. 2D electrical resistivity method is a geophysical method that utilizes dynamic electrical properties of the media path. 2D electrical resistivity measurements have been carried out in Kapuas, Central Kalimantan using Wenner configuration, the distance between the electrodes 10 meters, penetration depth reaches 80 meters, and and measuring some 21 track. Water potential zones were identified based on having resistivity range 15-25 ohm.m, contained in the sandstone layer, which is covered in a layer of impermeable mudstone layers. Location that has a high potential for groundwater recommended drilling done on the track P-07 and P-13, with an estimated depth of the aquifer between 25 meters and 30 meters. The highest groundwater potential lies between the drilling data PH-23 and PH-24, with the resistivity at that point reaches 300 ohm.m. Keywords : Groundwater, aquifer, sandstone, 2D electrical resistivity, resistivity, Kapuas

Abstract

Groundwater is one of the most important for human activities. The effects of land use and population changes in Bekasi area cause the degradation of groundwater quantity and quality. The aquifers potential in Cikarang and its surrounding as a study area are studied using geoelectric method. Geoelectric analysis can be measured the geometry of subsurface aquifer (thickness, depth, distribution, and structural geology). The aquifers in the study area are included of Bekasi Groundwater Basin System. The aquifers contain confined aquifer and unconfined aquifer. The thickness of unconfined aquifers less than 30 m, as lenses and bottom depth less than 40 m below of land surface. The thickness of confined aquifers is variation with maximum 80 m and the bottom depth 20-160 m below of land surface. The degradation of groundwater in Cikarang and its surrounding needs better groundwater management for sustainable development.          Katakunci : potensi airtanah, akuifer, geolistrik, Cikarang
