【 摘 要 】

This study aims to determine ground water level in Karanganyar regency, Central Java Province, Indonesia. Karanganyar regency is located in west flank of Lawu volcano, the third highest volcano in Central Java Province. Karanganyar lays from the top submit of Lawu volcano to down town of city with altitude 3265 m to 88 m. Same as other mountain area, Karanganyar has a lot of ground water potential. We use geoelectric method to finds out how deep of ground water level. The survey locations are distributed surround Karanganyar regency which contain 22 sites, in period survey of 2013 - 2015. Schlumberger configuration is used for acqusition data with lenght of current electrode distance varies from 1 m to 700 m. The result shows that ground water level are located in depth from 50 meter to 150 meter with lithology of tuff and sand. In Munggur and Kedung Jeruk sites, we found two potential aquifers, which are shallow and deep aquifers.
