【 摘 要 】

It has been done geophysics survey by using resistivity method with Schlumberger configuration in Sambirejo and Kedawung subdistrict, Sragen regency, Indonesia. This research aims to identification of aquifer potential in those area. Totally there are 22 site surveys where 11 sites located in Sambirejo and 11 sites located in Kedawung subdistrict. Data collection was performed by using Resistvitymeter OYO McOHM-EL with length of current electrode from 1,5 meter up to 350 meter. Data processing was done by using IP2win software, while cross section was processed using Rockwork software. The result shows that in Sambirejo subdistrict, the aquifer layer consist of clayey sand and sand, While in Kedawung subdistrict, The aquifer layers consist of clayey sand, sand, gravel sand, gravel and breccias. Identification of groundwater potential zones as good and very good category was show that the sounding point was have a huge of groundwater source for in Sambirejo subdistrict is TS2, TS5, TS7, TS8, and TS9, while in Kedawung subdistrict is TS13, TS14, T15, TS16,TS17,TS18, TS19, TS20, TS21 dan TS22, respectively.
