earth. The presence of groundwater is not evenly distributed for every place and is strongly related to its geological and geohydrological conditions. The research location is in Palanggai Village, East Sumba Regency, East Nusa Tenggara Province. Monthly rainfall according to BMKG climatology data in 2005 - 2013 was highest in December, which was 176.78 mm and the lowest was in August at 0.44 mm. This research was conducted to find out about the subsurface layer. Existing groundwater or aquifer carriers are using the geo-electric approach of the Schlumberger method. From the results of the study it can be concluded that (1) geo-electric estimation has been able to provide an overview of the state of the rock layers both vertically and laterally, (2) hydrogeological conditions in the investigation area, including aquifer systems with small to moderate productivity and is widespread, (3) rocks which are expected to be able to act as a limestone and limestone sand aquifer, (4) From the results of a geo-electric estimation investigation, it can be seen that the aquifer layer is found in depths ranging from 10-110m.
