“…Density and resistivity have values that vary from one material to another. Because of this variation, measuring the density and resistivity of unknown material is potentially very useful in identifying the material, with little more information [11][12]. In addition, the geomagnetic method can determine the depth and structure of the subsurface so that a clearer local and regional anomaly can be obtained [13].…”

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.

“…Indonesia is also among the many countries that have used the geoelectric resistivity method to conduct research pertaining to landslides. Some landslide research using geoelectric resistivity method are Rohadi et al (2018) in Lembang, Bandung, and Susilo et al (2018a, b) Some of these studies show that the geo-electric resistivity method can provide a good picture in explaining landslide analysis.…”

PurposeResearch has been conducted to analyze the landslide in Banaran area, Ponorogo Regency. The landslides occurred on April 1, 2017. This study was conducted to know the subsurface conditions in the Banaran area to analyze the disaster mitigation efforts. The mitigation efforts are made to reduce the risk from landslides and possible landslides.Design/methodology/approachThe method used is the geo-electric resistivity method of Wenner–Schlumberger configuration. The research was conducted in three villages namely Banaran Village, Bekirang Village and Mendak Village.FindingsThere are 12 resistivity measuring points with a track length of 410 m and a space of 10 m. The measured resistivity range is between 1.42 Ω.m and 67.500 Ω.m. The resistivity data and the local geological maps interpreted that the rocks in the Banaran area consist of clay, tuff lapilli, volcanic breccia and andesite lava. The landslide area begins at a depth of 8–35 m below the surface which is interpreted as tuff. Also, the thickness of the landslide material and the slope is = 400 which supports the occurrence of a more prominent landslide. The results of the parameter scoring of the landslide-prone areas indicated that the research area is very vulnerable to a landslide. The results of the interpretation indicate that the geo-electric resistivity method can provide a good overview for conducting landslide analysis, that is field slippage and potential material thickness occurrence landslide.Originality/valueThis article is very specific as it attempts to discover how prone Banaran are is to landslide.
