摘要

Geoelectrical is a method used to determine the conditions below the ground surface. There are several methods in geoelectrical namely resistivity, self-potential, and telluric current, electromagnetic, and induced polarization. In the research conducted at the University of Jember Bondowoso Campus using the resistivity geoelectric method to determine the value of resistivity distribution. In addition to geoelectric testing, drilling was conducted in the field to determine the value of soil characteristics. This research was conducted in 4 zones with an area of 45 × 29 m each. Geoelectric testing was carried out with a 72 m long track of 1 longitudinal track and 4 transverse tracks along 51 m in each zone with the Wenner-Schlumberger configuration. After taking resistivity data, field data analysis was carried out using Microsoft Excel software. The next stage is 2D data modeling using the RES2DINV application so that the resistivity value of 1–292 Ωm is obtained. The soil characteristics obtained from the results of testing using hand bore and laboratory testing are including the classification of sandy silt soil. After analyzing the results of the resistivity value and soil characteristics, it was found that the resistivity value will decrease if the value of moisture content, plasticity index, and cohesion increases. This is inversely proportional to the results of the relationship between resistivity value and shear angle.
