Optimization of Ocean Wave Energy Harvesting with Pontoon Model– Single Pendulum

Abstract

Renewable energy is energy that is needed in this modern era. The need for electrical energy in the present is a primary need, much of the sustainability of human life is supported by the existence of electrical energy. We are in Indonesia where Indonesia is a country consisting of many islands, and 77% of Indonesia's territory is water. By utilizing the energy contained in ocean waves to make electrical energy by using sea wave power plants. Ocean wave energy harvsting, single pendulum pontoon systems, are one of the alternatives to energy problems in this world. Simulations were carried out to determine the electrical energy to be obtained from the from ocean wave energy harvesting, single pendulum pontoon system. The simulation was carried out with matlab software by controlling the variable amplitude of ocean waves 0.0125m, 0.025m, 0.0375m, 0.05 m, and 0.0625m. From the simulation results, current, power and voltage data generated from the ocean wave power generation system were obtained. In this study, the results obtained were different amplitude levels that had a real influence on the results of current, power and voltage generated from ocean wave energy harvesting - single pendulum pontoon system using minitab software to process data with a complete random design method. Where the higher the amplitude of ocean waves, the higher the value of the results of currents, voltages and power generated by single pendulum pontoon model from ocean wave energy harvesting.
