چکیده
Gunung Kidul Regency is a highland consisting of carbonate rocks dominantly. Bedoyo village in Ponjong sub district has lot dolines, but the summer season, dolines become dry and could not be water storage. Geological mapping included geomorphological, rock observation, structural also petrographical analysis laboratory. A Geophysics survey to observe subsurface distribution laterally vertically with dipole-dipole configuration. The resistivity method determine value for depth fewer than 40 meters length electrodes about 250 meters. result geological geophysical review phenomenon that shallow aquifer. It caused by condition beneath carbonated poor porosity, lenses impermeable tuffaceous claystone, igneous rock. Those basements have moderate porosity less opportunity good aquifer if deeper an An alternative needed vertically.
