PEMETAAN AWAL POTENSI ENERGI LAUT DI PANTAI SELATAN PULAU JAWA DENGAN PEMODELAN HIDRODINAMIKA

Abstract

Ocean potential renewable energy sources can be utilized from currents, tides, thermal energy conversion, and wave. This study analyzed current velocity, wave height, and tidal range that can be converted to electrical potential energy in every ± 20 km segment along the coastline.Three-dimensional hydrodinamics model in this study used structured grid mesh from coastline, bathymetry data, tidal data, wind data, and rainfall information to define the model month selection. Tidal data from Geospatial Information Agency were used to validate the model. Due to wave height, the ocean potential energy from the wave does not meet the minimum value requirement based on the model processing and data analysis of 43 observation points. However, the potential of tidal energy generates greater and more equitable energy along the coast compared to the potential of ocean currents. There are 19 potential points for ocean renewable energy on southern coastal of Java reviewed from the road access around the coast. The average estimated power from tidal in February and October were 560468.327 kW and 373867.189 kW, respectively.
