Abstract:
The earth's material constituent areas prone to landslides in the area Sibiru-biru Deli Serdang has been conducted. The method used in this research is Geoelectric method, Wenner electrode configuration and Schlumberger two-dimensional electrode configuration. Field measurements are performed by using equipment Resistivitimeter Naniura brand NRD 22 S, data processing by using software Resistivity Inversion 2 Dimension (RES2DINV) for data geoelectric Wenner and Schlumberger electrode configuration. Based on the results shown by software obtained several rock layers at research location. The data processing geoelectric method using Wenner electrode configuration layer landslide prone fault at a depth of 0.775 meters - 1.35 meters with a value of 211 Ωm resistivity – 329 Ωm while the Schlumberger electrode configuration at a depth of 0.775 meters to a depth of 1.45 meters has a resistivity value 165 Ωm – 328 Ωm. Both results showed that the differences in resistivity values were not significant. This means that both methods can be used to identify areas prone to landslides with layers of rock.
