Abstract
Indonesian seas have not been used as a source of electricity yet. One of the potential and abundant sources of energy from the sea is ocean waves. This study describes the measurement of the wave characteristics and calculates its spatial and temporal energy in Pari Island which can be utilized as electrical energy using overtopping ocean wave power plants scheme. The energy that can be harvested from ocean waves is calculated by wave energy converter using the Wave Dragon WEC. This converter is the terminator type. Sea waves on the Pari Island are classified as the smooth sea with 0.16-0.51 meters significant wave height and 2–4 seconds period. The calculated WEC can produce energy up to 28 Mega Joules and power up to 6 Mega Watts. Based on this calculation, Wave Dragon which is an overtopping WEC is able to meet the electricity needs on Pari Island with two options, The first one is using 35 units of WD 1 on the Pari Island Coast with a 500 m distance from the settlement, or the second one is using 6 units of WD 2 which is located in the northeast region of Pari Island waters with 18 Km distance from the settlement of Pari Island.
