【 摘 要 】

Ocean waves are a renewable energy source with abundant reserves in Indonesia. Withthe vast waters of Indonesia, the development of a sea wave power plant needs to be developed.This research focuses on the development of easy-operated and maintained ocean waveconverter–pendulum system (OWC – PS). The numerical simulation and experimental analysiswere conducted to obtain the relation between the motion response of the pontoon array and itspendulum. The pontoon used is the trimaran type, which consists of a cylindrical pontoon asthe main hull and two outriggers on its side. This study analyses the most stable arrayarrangement that produces maximum pitching motion and pendulum deviation. The simulationresults show that the largest pitching value is in array 1, i.e., 27.91° for pontoon 1 and 38.92°for pontoon 2, which results in a maximum pendulum deviation of 100 ° for pendulums 1 and56.2 ° for pendulum 2 over a wave period of 9 seconds. The backward motion of the pendulumin both array configurations tends to have a greater deviation than that of the forward motion.The pendulums of array 1 have different motion characteristics, represented by differentdeviation values in both pendulums. This phenomenon does not occur in array 2, since bothpendulums in array 2 have the same deviation (with only a small discrepancy).
