Abstract

Based on the observation that have been done in Jatilor village, the use ofÂ dig well have been done to fulfill the need of fresh water with about 5-20 m depth. But some dig well with less than 7m depth can't fulfill the need of fresh water because ofÂ the water is empty due the dry season. The people in this area haven't know the spread and the depth of ground water. The aim of this research is to know the spread and the depth of ground water. The method to get the aim is configuration dipole-dipole geoelectric research with 6 line in this area. The result shows us that the sheet with resistivity interval 300-500 is the napal, gravel and limestones sheet. The sheet with resistivity interval 100-200 is the gravel, silkclay and sand. The sheet with resistivity interval 0,225-20 is soil, clayÂ and Unconsolidate wet clay. The potential line that had ground water is location with point e 110 48.755's 07 02.318' with dig well ground water about 4,62-17,9 m depth.
