Wave energy potency in East Java coast

Abstract

It is predicted that in 2025, Indonesia energy needs is going to reach 280% of current needs. Presently, the renewable energy has only contributed 5.7% of total energy supply. The aim of this research is to investigate wave energy potency in several coasts of East Java which were Pacitan, Jember, Besuki and Tuban. Wave data (significant wave heights and wave periods) were obtained from the ERDDAP server (Environmental Research Division's Data Access Program). Southern East Java Coast showed potency for ocean wave energy resources. The coast of Pacitan had energy of 232 MWh/m/year and the coast of Jember had energy of 190 MWh/m/year.
