Abstract :
The country of Indonesia is a country that is between the Continent of Australia and Asia,
as well as between the Indian Ocean and the Pacific Ocean. The geoelectric method is one of the
methods used to determine the nature of electric current in the earth by detecting it on the surface
of the earth. This detection involves measuring the potential, current and electromagnetic fields
that occur both by current injection and naturally. One configuration used for research is the
dipole-dipole configuration. The results of research that have been done, obtained several rocks
based on the length of the measurement range. At a length of 30 meters, rock types can be known,
namely Quartz, Rock Salt, Granite, Andesite, Basalt, Limestone, Sandstone, Slate, and Dry Gravel.
At a length of 40 meters, it can be seen the types of rocks, namely Quartz, Rock Salt, Granite,
Andesite, Basalt, Limestone, Sandstone, and Dry Gravel. At a length of 50 meters to 80 meters, it
can be known the types of rocks, namely Quartz, Rock Salt, Granite, Andesite, and Basalt. At a
length of 90 meters, it can be seen the types of rocks, namely Quartz, Rock Salt, and Andesite.
