T he research area is administratively located in Minahasa District, North Sulawesi Province. The object of research in this study is the geochemical characteristics and the determination of the recharge area with stable isotopes. There are two types of emerging manifestations: hot springs and fumaroles. The hot springs that appear to the surface have a low temperature below 90 ° C with a water sulphate type and bicarbonate water. This manifestation arises from tectonic activity working in the study area. The field is dominated by volcanic rock lithology. Geotermometer calculation results show that this field has high-temperature geothermal system with temperature range 270oC to 310oC. This field upflow zone is located in the northern part of the research area. Fluid flows to the East towards the outflow zone. The catchment area in the "HBD" area is divided into two, namely the recharge area for the geothermal reservoir and the manifestation catchment area (hot springs). The recharge area for geothermal reservoir lies in the ± 480-830mdpl elevation range and the recharge area for the manifestation lies in the elevation range ± 1.020-1.330mdpl.
