Abstract

This research aimed to determine location and distribution of groundwater in Bapangsari, Bagelen, Purworejo. This research used Vertical Electrical Sounding (VES) method with Schlumberger configuration. Research data were taken by using resistivity meter IPMGEO. This research did on 2 locations with length of line is 180 m. The data were processed using software Microsoft Excel and IP2WIN. Based on result of the research. On the first location, groundwater is at 32,2 m depth with 3,3 m thick. On the first location, groundwater is at 34,6 m depth with 9,58 m thick. Groundwater on the first location is shallower than second location. However, on the first location have over burden. The over burden has big enough resistivity value (higher than 100 ohm m). This value has been identifying of a solid layer. The layer is andesitic breccia. While on second location, the over burden has small enough resistivity value (50 ohm m). This value has been identifying of a sedimentary layer. The layer is weathered breccia and gravel.

Abstract

Research was conducted to determine distribution of Conglomerate in Surodadi Village, Gringsing, Batang. The data acquisition used Schlumberger array. The length of line is 165 m and 15 m electrode spacing. The data processing used Microsoft Excel and 2D imaging used Res2Dinv. Then 3D imaging used Rockworks from result of Res2DInv inversion. The position data was used on UTM coordinate from position data each of electrode. The data acquisition was done at two parallel lines. In this area was found two types of rocks; tuffaceous sandstone and conglomerate. The conglomerate with resistivity values higher than 180 Wm is distribution on southeast research area at the depth 5 m – 25 m. While the tuffaceous sandstone layers is distribution on northwest research area.
