Abstract

It has been 67 years since Indonesia^s independence, but equal distribution of access to electrical energy has not yet been fully felt by all Indonesian people living in the Frontier, Outermost and Disadvantaged (3T) areas. This condition occurs as a consequence of the vast territory of the archipelago, the uneven distribution of electricity generation sources, and generating capacity which is unable to keep up with the high rate of growth of electrical energy, this clearly hampers economic growth and can reduce the nation^s competitiveness. In order to solve this problem, a power plant is needed that can utilize local potential as a source of electrical energy. One source of electrical energy that has great potential is ocean wave energy, because this energy source is quite abundant in 3T areas, islands and coasts, has a high energy density, unlimited potential area, and is included in the category of environmentally friendly and renewable energy sources. However, the use of this energy still has weaknesses in terms of the low stability of the voltage and power produced and the lack of a comprehensive ocean wave energy potential map. The efforts made are to build a hybrid power plant that combines a sea wave power plant that utilizes vertical wave energy into motion energy to pump sea water into a pressurized reservoir to spin a water turbine connected to an electric generator with abundant wind energy as well as carrying out mapping. potential application in Indonesian seas. In this article, we will present the potential for ocean wave energy in the Java and Sumatra seas.
