Abstract
Geothermal is one of alternative energy which is very potential to produced in Indonesia
because Indonesia have 40% world geothermal reserve . Nowadays, geothermal
potential in Indonesia up to 28,5 Giga Watt (GW). Whereas Installed Geothermal Power
Generator only about 1948,5 MW. North Sulawesi is one of geothermal generating area
in Indonesia, spesifically in Minahasa Compartment. Research area geomorphologically
consist of Volcanic Hill Unit, Volcanic crater lake Unit, Tampusu Volcanic slope Unit,
Kasuan Volcanic slope unit, and Tondano Caldera slope Unit. Research area composed
of Volcanic products with volcanostratigraphy from the youngest is Pangolombian
Volcanic Breccia Unit, Tampusu Basaltic Andesite lava unit, Linau basaltic andesite lava
unit, and kasuan basaltic andesite lava unit. Geothermal manifestation in research area
consist of Linau Fumarol, Leilem Hotspring, Lahendong I and II Hot spring, Leilem
Mudpool. Fluid geochemistry analysis shows all manifestation samples are steam heated
water and immature water. While well “X” fluid sample shows Sulphate-Chloride water
in partial equilibrium to immature condition. Hydthermal alteration in well “X” consist of
Kaoline±Smectite±Chlorite
zone,
Kaoline±Illite±Sericite
zone,
and
Epidote±Hematite±Chlorite±Illite zone. Geothermal reservoir temperatur based on Linau
Fumarole Geothermomether about 292

C. Depends on reservoir temperature, “KU” Geothermal Field is High Temperature
Geothermal System.
