“…Resistivity values that are close to actual conditions were obtained by carrying out a least squares inversion process using IP2WIN software [19], [20]. The less square inversion method uses a mathematical approach to obtain the smallest difference from the error of the smallest resistivity value to the actual resistivity model [21].…”

The drought in Banyol Hamlet, Malang Regency, severely impacts community sustainability. This problem can be overcome if the hamlet has a groundwater source; theoretically, groundwater can be detected using geoelectric resistivity. This research aims to investigate the existence of aquifer layers in Banyol Hamlet, Malang Regency, using the resistivity method Schlumberger configuration. Resistivity data was measured at 5 points with a track stretch of 400 m and a distance between electrodes of 5 m; then, three parallel measurement points were interpolated into a 2D cross-section. Based on the analysis, the presence of the aquifer is considered to be in the breccia tuff layer because the resistivity value is lower than usual in this layer. So, we assume that the tuff breccia rocks can act as an aquifer in the study area. The results of the 2D cross-section show that the shallow aquifer is found at a depth of 10-22 m with a resistivity value of around 30.78 Ωm - 314 Ωm. and a deep aquifer at a depth of 40-125 m with a resistivity value of around 22.34 Ωm - 192 Ωm. So drilling is recommended at measurement points SS-1 and SS-3 in deep aquifers because the thicker the soil layer, the more water infiltration.

“…Due to the saturation, besides an increase in pore water pressure, the weight of the weathered materials also increases, disturbing the balance of the slopes and thereby causing instability of the slope materials. [24][25][26][27][28][29] The clay-bearing rocks exhibiting low resistivity on the other hand are the least permeable and considered a waterproof layer, which is capable of acting as the probable layer for the initiation and planeof movement of the weathered materials. This acts as one of the primary factors for the cause and further development of landslides.…”

Vertical Electrical Sounding (VES) technique which employs the Schlumberger depth sounding method was used to investigate the subsurface conditions at the landslide in Perizie colony, Kohima. The interpretation of the VES curves shows differing lithology consisting of weathered shales with associated clay, which is considered an important factor for slope instability. The shear strength of the slope materials, including the country rocks and the soil cover, is also significantly reduced and easily detached due to the effects of weathering and erosion, causing the landslides. Three to six possible geo-electric layers are delineated from the variations in the resistivity values, with the lithologies consisting of topsoil followed by alternate layers of weathered and fractured rocks of varying thickness. The analysis also points to the presence of a weak zone at a depth of about 10 m, which is not apparent from the surface. The formation of groundwater aquifers in the fractured zones indicates high risk for slope failure as this accelerates the weak country rocks to weather. The results obtained by this study correspond well with the available borehole data of the area.

“…The geophysical methods used in this study were the gravity method of satellite imagery and the resistivity method, the Schlumberger configuration. The gravity method was used to measure rocks' density properties below the surface, which were influenced by its gravity field, while the resistivity method was used to estimate subsurface geological conditions by utilizing the nature of electric currents in rocks with the earth being used as a conductor [10]. Density and resistivity have values that vary from one material to another.…”

Research with the gravity data of satellite imagery and resistivity methods, Schlumberger configuration in the area of Sutami dam, and its surroundings has been undertaken. This study aims to determine the types of rock layer contact between limestone sediments and volcanic sediments for disaster mitigation. The Gravity data of satellite imagery was obtained from the Global Gravity Model Plus (GGMplus). The research area was 15 km x 15 km; the space between the points was 300 meters with 3000 measurement points. Resistivity data was obtained with an MAE type A6000E resistivity meter; the number of research points was 2 sounding points arranged in parallel to get 2D data. The location of data collection with the resistivity method, Schlumberger configuration was determined based on the results of research using gravity data of satellite imagery. Complete Bouguer anomaly values ranged from 73.6 mGal-89.3 mGal. The northern part of the research location has a lower Complete Bouguer anomaly than the southern area. It was because the northern part of the study area was part of volcanic sediment, although it was only on the surface, and the southern part was part of limestone sediment. Based on the value of resistivity data, the types of rock at research points 01 and 02 were soil, limestone, and sandy limestone. It was because the research point was located in a Campurdarat Formation. The results indicate that the contact layer between limestone and volcanic sedimentaries is located in: Campurdarat Formation, Wuni Formation, and the Butak Volcanic Product; Nampol Formation and Tuff Deposit; Tuff Deposit and Campurdarat Formation. This contact layer is more difficult to consolidate, so infrastructures built on it are more vulnerable.
