A Analysis of a geothermal characteristic is very important to be carried out inorder to properly describe the geothermal characteristics of the area as renewableenergy. The "F" geothermal field is a geothermal field located in three regencies,namely Malang, Mojokerto, and Pasuruan Regencies and Batu City, East JavaProvince. Based on geological and geochemical conditions in the study area, itsupports the creation of geothermal models. The purpose of this study is to analyzethe geochemical water, gas, and isotope, subsurface temperature, upflow andoutflow zones, as well as geothermal models in the study area. The method used isin the form of geological analysis and analysis of fluid, gas and isotopegeochemical data. Geomorphologically, the research area is divided into 14 unitsbased on the provisions of the shape of the volcanic earth. The geothermal systemin the study area is included in the liquid dominated system-high relief.Manifestations that are exposed to the surface are warm spring, fumarole, andsolfatara. The type of water in the study area is bicarbonate water and rockreservoir in the form of volcanic igneous intermediates. The calculation of the watergeothermometer is found to range from 152.02°C-166.17°C and the reservoir inthe gas is 255.34°C-306.63°C. Based on the results of the reservoir temperaturethe study area is classified as high temperature. The source of gas in the study areais sourced from magmatic gas. Isotope analysis shows the source of water comesfrom meteoric water while the Welirang Peak comes from magmatic water. Theupflow zone is in the middle of the Welirang Peak and the outflow zone is in thewestern and northwestern parts of the study area, namely to the Coban, Padusan,and Pundak areas.
