� “JK” field is a geothermal field located on Central Maluku District, Maluku Province. The main objectives of this research is to identify geothermal prospective area on “JK” field by analysing lineament that showed up on satellite image and by employing magnetotelluric data, as well as producing geothermal system conceptual model . Lineament analysis method is used to give information on area with high FFD values, that is associated with the occurrences of geothermal system below the surface. Lineament analysis is also backed and supported by magnetotelluric and geology data to confirm the analysis. Based on the descriptive norm, “JK” field is categorized as low-relief liquid dominated geothermal system. Based on lineament analysis, 4 structural trends are detected (N303˚E, N32˚E, N60˚E, dan N75˚E) that corresponds to the geological structures that shows up on study area. Based on the FFD map, “JK” Field is divided into 2 structure density classes, namely high structure density (≥ 3km-1) and low structure density (≤ 3km-1) and all hotspring manifestations occurs on high structure density area. Based on the MT data, clay cap zone started from 0 m to ± 350 mbsl on lateral resistivity map and from 0-±650 mbsl on resistivity cross section, meanwhile reservoir zone can be found at depth starting from 500-1000 mbsl and both the clay cap and the reservoir is located near and around Banda and Banda-Hatuasa Fault. Based on water geochemistry, manifestation water can be divided into 2 types, namely chlorida water (STE 1,2,3,4,5,6,8,9) and dilute chloride-bicarbonate water (STE-7). The upflow zone is located around Banda and Banda-Hatuasa Fault, and the outflow zone is located on Tulehu Fault, the direction of fluid flow (lateral flow) is south west to north east. Based on geoscience compilation map, “JK” field geothermal system can be identified by the occurences of resistive body at depth (≥ 25 ohm-m) and area with high FFD values. In conclusion, the prospective area is located north west of Mount Eriwakang with an area of about 5.25 km2 , that area is assumed to have a good permeability and high temperature.
