Abstract

The south coast of Java has great potential for Wave Energy Converters (WECs). This study presents quantities of interest for wave energy converters from the vertical kinematic motion of ocean waves. The study site is located on Binuangeun Beach on the southwest coast of Java. A prototype and mechanical calculation of ocean wave energy conversion based on previous research. The data source used in this study comes from in situ measurements and wave reanalysis models. Wave height and energy dynamics are analyzed and displayed as wave spectrum and time series plots. The calculation of extreme waves is also included in the analysis. Calculation process using Python software by inserting wave height and load spectrum obtained from a significant height, peak period, and wave energy spectrum. Electricity generated from WEC is shown as average annual energy production and performance metrics. Seasonal variation of wave height provides variable power output. However, the calculation results show that the study area has a potential for wave energy above 5 kW/m, which can be applied as a test site for a wave energy conversion power plant.
