Abstract
This study aims to analyze rock units containing aquifers in the location of investigation using geoelectrical measurements with Schlumberger configuration method of the MC OHM 2115 Resistivity Meter. The estimation was carried out in 12 measurement points with the length of each path was 150 m. The data analysis of the measurement was implemented using IP2WIN software and Corel Draw X6 software. The results of the interpretation of the 12 measurement points indicated that there were 5 rock units, namely the resistivity 0 ≤ 2 Ohm m which is interpreted as clay. Resistivity 2, 5 ≤ 10 Ohm m as marl. Species resistivity 10.5 ≤ 20 Ohm m as marl limestone, while resistivity ≥ 20.5 Ohm m as reef limestone. The aquifer belongs in the reef limestone unit with a specific resistance of 20.5 ≤ 100 Ohm m which ends with an impermeable layer such as clay or semi impermeable such as marl. Based on the interpretation, it is concluded that along the measurement area there are aquifers with varying depths which can be optimized by means of drilling at points 01, 03, 04, 06, and 09. The location that has the thickest aquifer is point 04 (± 29.3 m) and 09 (± 38 m).
