Starting mid of 2008 (Semester I/2008-2009) the Faculty of Mining and Petroleum Technology (FTTM) - ITB offers a Master Degree Program in Geothermal Technology. This program is a four semesters intensive program, which can be completed in three semesters, put strong emphasis on technical and practical aspects (profesions) of geothermal energy exploration, exploitation, utilization, economics, management and environmental.
Geothermal Energy in Indonesia, Current Status
Indonesia has a big potential of geothermal energy, as the country lies along the Ring of Fire where most of the volcanoes are located. There are 256 geothermal areas have been identified in Indonesia, of which 84 geothermal areas have been identified in Sumatera, 76 areas in Jawa, 51 areas in Sulawesi, 21 areas in Nusatenggara, 3 areas in Irian, 15 areas in Maluku and 5 areas in Kalimantan.
Most of geothermal systems in Indonesia has high temperature, mostly above 225oC, very suitable for electricity generation. The Geological Agency (Badan Geologi) of the Ministry of Energy and Mineral Resources has identified 299 geothermal areas in Indonesia with a total electricity potential of about 29,000 MW including 16,482 MW of reserves, consists of 2,288 MW of proven, 823 MW probable, and 13,371 MW possible reserves (Sukhyar, 2012).
The following figure shows the current status of Geothermal Energy Development in Indonesia, as summarized from a number of sources: i.e Surya Drama (2010), Sukhyar (2013), Abadi Poernomo (2013).
To date, only 9 areas have been utilized for electricity generation, with a total installed capacity of 1,341 MW; Kamojang (West Java, 200 MW), Darajat (West Java, 270 MW), Awibengkok, Gunung Salak (West Java, 377 MW), Wayang Windu (West Java, 227 MW), Sibayak (North Sumatra, 12 MW), Lahendong (North Sulawesi, 80 MW), Dieng (Central Java, 60 MW) and Ulubelu (Ulubelu-Sumatera, 110 MW), Ulumbu (5 MW).
Plan of Development
In 2005 the government of Indonesia set a target to increase the capacity of geothermal power plants from 807 MW to 9,500 MW by 2025.
This road maphas beenrevisedseveraltimesdue toproject delays caused by various reason, but mainly because of low electricity price, overlappingland use regulations between geothermal and forests, legal aspects, financing.
