Investigation of Jabung Temple Subsurface at Probolinggo, Indonesia Using Resistivity and Geomagnetic Methods

Abstract

Subsurface structural estimation has been investigated with dipole-dipole resistivity configuration and magnetic methods for mapping of Jabung Temple Archaeological Site located in Jabung Village, Paiton Sub-District, Probolinggo Regency, East Java with Resistivity meter OYO MacOhm and Proton Precession Magnetometer. This estimate aims to determine the spread and depth of the rocks below the surface of the Archaeological Site of Jabung Temple as well as a source of information for the discovery of ancient objects still buried in the soil. The acquisition of resistivity data was performed on ten measuring tracks and covered the measurement area of ± 37,900 m 2 . Six trajectory tracks are located around Menara Sudut Temple and four line are located in the area of Jabung Temple. The acquisition of magnetic data is made around the area of Jabung Temple at 924 points with spacing of 2.5 meters, with the area of 5,200 m 2 . Based on the interpretation of magnetic anomaly and resistivity data, the magnetic anomaly value, <16.9 nT is likely to indicate the remains of temple ornaments located at a distance of 20 meters in front and behind the main temple. This is supported by a resistivity value from 33.0 Ω.m to 92.6 Ω.m which indicates the remains of the temple building blocks. The depths of the remains of temple rock are thought to be at an average of 1.8 meters below ground level. Magnetic anomaly is high in the main temple, equal to > 22.6 nT due to andesite rock used as a temple booster (based on information obtained during the restoration of 1983/1984). The results of this study indicate that geoelectric and magnetic methods are very effective for the prediction of subsurface structures, especially in the archaeology field.

Analysis of Landslide and Land Subsident Using Geophysical Method in the East Java Province, Indonesia

“…Jawar Hamlet, Sri Mulyo Village, Dampit Subdistrict, Malang Regency is one of the villages prone to landslides in East Java Province [3], Preliminary Study of Landslide In Sri Mulyo, Malang, Indonesia Using Resistivity Method And Drilling Core Data). On January 24, 2006, there was a landslide in the village which caused 1 house to be destroyed, 14 houses cracked on the walls and foundation.…”

“…Geophysical method is a method to determine the subsurface conditions of the earth based on physical parameters. The resistivity method is one of the most widely used geophysical methods in the fields of hydrogeology, disaster mitigation, and archeology [5][6][7][8][9]. Several previous studies has shown that the resistivity method is effective for knowing the subsurface conditions of landslide-prone areas [4,[10][11][12][13][14].…”

Groundwater Investigation Using Resistivity Method and Drilling for Drought Mitigation in Tulungagung, Indonesia

“…One of the geoelectrical methods is the geoelectric resistivity method. Geoelectric resistivity surveys have been used for decades, in hydrogeology for the determination of the aquifer, mineral investigations, geotechnics, structural geology (fault), and the determination of archaeological traces [2][3][4][5][6][7] The configuration used in the geoelectric resistivity survey has many options, one of which is the Wenner-Schlumberger configuration. This configuration is the right choice for the depth target(sounding) or commonly known as Vertical Electrical Sounding (VES).…”

“…In principle, a current is injected through two current electrodes, and then a potential difference is measured through the two potential electrodes [1][2][3]. Resistivity surveys have been used for decades in hydrogeology to detect water or aquifer layers, mining or mineral investigations, and geotechnical to know the subsurface structure, even now it is also used for environmental surveys to detect environmental pollution [4][5][6][7][8]. There has been much research on groundwater investigations using geoelectrical methods [9][10][11][12][13][14][15][16].…”
