Abstract- Ratio of fossil
energy use and clean energy use in Indonesia is 65.5:8.5 with 187.32 million
cubic ton carbon emission on 2010. Indonesia is an archipelago country that has
great wave energy potential to produce electricity. Sea wave is an eco-energy
that can produce about 20-70 kWh/m. South Java shores has great potential as
sea wave energy location especially at Gunungkidul district that its region
characteristics formed by karst/limestone. This research has a purpose to
determine the area suitability for onshore sea wave energy power station
through GIS, spatial land analysis, and weighting method. Area suitability
level is grouped to suitable (S1), suitable conditional (S2), and not suitable
(N). Weighting method uses this following parameter: shore morphology, sea
depth, shore tilt, wave type, wind velocity, and wind direction as early
appraisal for area suitability identification to place onshore sea wave power
station in Gunungkidul Regency.
