Analisis Penyebaran Menggunakan Metode Geolistrik Konfigurasi Wenner Di Kelurahan Simpang Baru
ABSTRACT
The horizontal distribution of groundwater points and general description of
subsurface lithology, especially rocks containing groundwater using the
geoelectric method have been investigated. The geoelectric method is a
geophysical method used to determine the geological conditions of the subsurface
of the earth based on variations in the resistivity values of the rock types. The
method used in this study is the Wenner configuration geoelectric method. This
method has several advantages, such as good vertical resolution and high
sensitivity to lateral changes. Apart from knowing about the distribution and
depth of subsurface water, and subsurface conditions, data from research results
in the Simpang Baru Village area can be used regarding the need for clean water
for the community. Data obtained from measurements using the Wenner
configuration geoelectrical method are processed to obtain resistivity, while for
interpretation uses the software Res2Dinv. On a track with a length of 100 meters,
it has a depth of up to 9,56 meters below the surface with a resistivity value with a
lowest one of 1.06 Ωm and the highest one is 9935 Ωm. The points of water
distribution at depths of 0,75 – 9,56 m have resistivity values of 1,06 – 53,5 Ωm
corresponding to the horizontal line at points with an electrode span distance of 5
– 94 meters.
