Abstract


The prospect ofgeothermal field of Cangar’s in Batu, East Java has been observed based on the geomagneticmethod using aProtonPrecisionMagnetometer (PPM-856).The purpose is to know the magnetic anomalies around the geothermal area. The resultsshown that the residual anomaly distributed in the range of -1.000 nT to 680 nT and the low anomaly(negative) at about -1.000nTlocatedonthe northand westof themanifestations ofhotwater. Geothermalpotential based on the subsurfacemodeling of the structures on the line A-B at position 49 M 0669,071.13174 mT UTM 9,144,184.60107 mU has a value of susceptibilitycontrast of -3.166with a volume of ± 1,550,345m3. Furthermore, on the line C-D at position 49 M 0669,168.601085 mT UTM 9,143,915.10292 mU shown a value of susceptibilitycontrast at -0.018with thevolume of ± 16,610m3.
