Abstract

Indonesian regions in some areas have the potential for renewable marine energy so that it can be utilized into clean and environmentally friendly hydrokinetic energy. The energy is divided into 4 namely sea water, sea water temperature, sea water waves, and sea water currents or tides. This research utilizes wave and current energy which is a form of renewable energy and has great potential with very large reserves, so that it can be utilized for electrical energy. Darrieus hydrokinetic turbine as an ocean wave energy converter device. Simulations were conducted to analyze the effect of blade profile on the value of Coefficient of Torque (CT) and Coefficient of Power (CP). In this study, wave data from one of the Southern Java Waters was used which resulted in the highest Coefficient of Torque (CT) value on the blade profile with a variation of TSR = 0.5; ? = 1 and solidity 0.3 angle of attack 10° resulting in a CT value = 0.134 and the highest Coefficient of Power (CP) value on the blade profile with a variation of TSR = 2; ? = 4 and solidity 0.3 angle of attack 10° resulting in a CP value = 0.257.
