Two Dimensional of geoelectric method can be used to find out the conductive formation in the earth surface.
The purpose of this research is to give the description about the geological subsurface formation, that the high
resistivity value is indicate the potential area of cave and void in the limestone rocks.
The dipole dipolegeoelectric method is used in this research with the path of lines is 250 m with 10 m electrode
spacing. The total lines is 7 and the azimuth is from east to west. Resistivity method is started with inject the
electrical current into the earth by current electrode, then potential difference will arise and measured by
potential electrode. Variation value of resistance for each layer rock can calculated by divided potential
defference with current value.
The existence of the cavity is known by the resistivity value is more than 2500 ohm-m, while the cracks have a
resistivity of 1500 to 2500 ohm-m.
