Renewable energy is a promising potential for the future, where this energy is low emission and environment friendly. One of the renewable energies that are abundant and rarely used is ocean waves. Energy from ocean waves can be extracted using an ocean wave power plant with a pendulum system (PLTGL-SB). The main components of PLTGL-SB are pontoon and pendulum, where the pendulum will oscillate when ocean waves hit the pontoon. This research will analyze PLTGL-SB with a two-axis mechanism. The analyzes were performed with simulations using CFD applications (computational fluid dynamics) and only used three degrees of freedom (pitching, rolling, and heaving). The design of PLTGL-SB has a length of 2.2 m, a width of 1.3 m, a height of 1.61 m, and an overall mass of 199.5 kg with two axes and two pendulums on each axis. The highest simulation results obtained a maximum deviation angle of 32.31° and an angular velocity of 1.44 rad/s with 10 kg pendulum mass and 1.0 m pendulum length at 0.5 m wave amplitude. If this design is used in the rumah apung Bangsring, it will require seven modules of PLTGL-SB and two additional 12V 50Ah batteries.
