Abstract

The rapid population growth rate in Bandar Lampung City has an impact on the rapidly increasing demand for groundwater. This study aims to map groundwater basins in the Bandar Lampung area. It is necessary to carry out management and monitoring to monitor the availability of groundwater in the research area with an understanding of the existence of basins in the research area. Mapping of the subsurface basin was carried out using the gravity method to see the distribution of gravity anomalies in the study area. The low Bouguer anomaly which forms a circular closed closure is interpreted as a subsurface basin zone which is assumed to be a groundwater basin flanked by bedrock heights indicated by high gravity anomalies. 2D modeling of the research area can also show the presence of a basin and elevation zone composed of 4 rock layers, namely andesite, sandy tuff, clay tuff, and lava (andesite-basalt). The Bandar Lampung Basin is identified as being in the eastern part of the study area.
