Abstract
The issues of energy crisis and high dependence on fossil fuel sources highlight the need for the development of environmentally friendly and sustainable renewable energy. As an archipelagic country, Indonesia holds great potential for harnessing wind and tidal energy. This study aims to analyze the power efficiency of an offshore hybrid system that combines wind turbines and tidal turbines, compared to conventional single-source systems, based on geographical differences in the waters of Jeneponto, Bali, and Maluku. The methodology includes turbine and semisubmersible platform geometry modeling, Computational Fluid Dynamics (CFD) simulations using ANSYS Fluent to obtain torque and power coefficient (Cp) values, and the conversion of Cp into electrical power output. The simulation results show that Maluku offers the most balanced hybrid system performance, with power distribution of 65.02% from the wind turbine and 34.98% from the tidal turbine. In contrast, Jeneponto and Bali are more efficient when focused on a single dominant energy source, with wind turbine efficiency at 96.58% and tidal turbine efficiency at 92.25%, respectively. Due to the relatively small contribution from secondary sources, focusing on the dominant energy source is more beneficial. Nevertheless, the hybrid system remains superior in generating more stable and higher power output, especially when tailored to site-specific characteristics, making it a promising solution for marine energy development in Indonesia.
