摘要：Energy conversion technology derived from ocean wave energy has been developed, one of them is the Power Wave sea- Pendulum System (PLTGL-SB). PLTGL composed of a pontoon which is subjected to the excitation force of ocean waves and will move the pendulum on the top of the pontoon. This study aims to analyze the best shape for PLTGL- SB’s pontoon and determine the largest deviation generated due to the movement of the pendulum vertical pontoon. Pontoon shapes studied are pontoon consisting of a large cylinder in the middle and there are two boats on the right and left, like a trimaran ship. Variations were made in this study consisted of variations of length and height boats, the draft height, wave period, the mass and the length of the pendulum arm. Best pontoon shape is determined by simulating the shape of a pontoon with Computational Fluid Dynamic (CFD). Pendulum deviation obtained by mathematical modeling pontoon two degrees of freedom (roll) and pendulum. Based on the chart Response Amplitude Operator (RAO) pontoon shape is best for PLTGL-SB is a pontoon with a 2/3 full large cylinder diameter, 1.5 cm height boats, catamarans length of 41.5 cm. Based on the results of a mathematical model of the largest deviation of the pendulum is generated when the pontoon is placed in the period of 0.8 s, with a mass and pendulum arm lengths are 19.9 g and 10.6 cm.
