Ocean waves are a renewable energy source with abundant reserves in Indonesia. With the vast waters of Indonesia, development sea wave power plant needs to be developed. This research focuses on easy-operated and maintained ocean converter–pendulum system (OWC – PS). The numerical simulation experimental analysis were conducted obtain relation between motion response pontoon array its pendulum....
