Identifikasi Akuifer Air Tanah menggunakan Metode Geolistrik di Perumahan Gang Jati Baru, Hajimena, Natar, Lampung Selatan

Abstract

Groundwater is a basic human need. However, the residents of Perumahan Gang Jati Baru, Hajimena, Natar face significant challenges in meeting their water demands, particularly during the dry season when water availability is critically reduced. To explore groundwater resources in Perumahan Gang Jatibaru, geoelectric measurements need to be conducted. The Schlumberger configuration is used for 1D measurements, while the Wenner-Schlumberger configuration is used for 2D data acquisition. The modeling results indicate the presence of shallow groundwater aquifers at depths ranging from 11.1 to 28.3 meters, and deeper aquifers at depths between 42.7 and 79 meters, characterized by low resistivity values of approximately 13.2 13.2 ohm.m. These findings are corroborated by the 2D resistivity modeling conducted at the study site, which reveals a shallow low-resistivity anomaly (<15.2 13.2 ohm.m) occurring at depths of 10 to 28 meters.     Groundwater is a basic human need. To meet the groundwater needs in the Perumahan Gang Jatibaru, Hajimena, Natar, geoelectric measurements need to be carried out. The geoelectric configuration used in 1D measurements is Schlumberger. Meanwhile, in 2D data acquisition, the Wenner-Schlumberger configuration is used. The modeling results show that shallow groundwater aquifers are located at a depth of 11.1-28.3 meters and deep water aquifers are at a depth of 42.7-79 meters with a low resistivity value of 13.2 ohm.m. These results are in line with 2D modeling at the research location which shows a shallow low resistivity anomaly (<15.2 ohm.m) at a depth of 10-28 meters.
