Abstract

The dependency of the forefront islands towards non-renewable energy resulting in difficulty to use this energy in the future. Sungai Suci Beach is the beach that has steep topography and high waves because it is directly facing with Indian Ocean. Based on an initial analysis, Oscillating Water Column (OWC) fixed on-shore tool is suitable to be implemented in this location. This research was conducted through collecting wind, tides, bathymetry and beach slope data. The wind data was used for wave hindcasting using SMB method. Tide data was processed by using Admiralty method. Based on hindcasting wave using 17 years wind data, the average of significant wave height were 2.3 meter and periods 8.5 second with energy availability 67 %. The capacity of power that could be generated was 1.0073 MW and categorized as small hydro. In a review of coastal bathymetry and slope, depths ranging from 0 to 25 meters, and the cliff slope average was 74 degrees. Based on the tidal analysis, OWC’s top side must be built taller than 1.71 meters and the lowest side should be lower than 0.21 meters from MSL. Through this analysis, OWC quite potential to be implemented in the Sungai Suci Beach Bengkulu.
