According to data from the Indonesia Ministry of Maritime Affairs and Fisheries, Indonesia has around 5,800,000 square kilometers of ocean with a coastline of around 97,000,000 kilometers. As archipelagic country with many territorial waters, it is not surprising that many Indonesians choose to work as fishermen. Based on data from National Destructive Fishing in 2013, the number of traditional fishermen reached more than 864,000 people. But unfortunately, the majority of these traditional fishermen belong to the lagging community of technological progress, including electricity needs. In fact, electricity is now a core requirement for every human activity. Therefore, it is necessary to get alternative and renewable electrical energy that utilizes daily fishing activities. Renewable electrical energy that the authors offer comes from the utilization of sea water waves assisted by the performance of cantilever piezoelectric. Piezoelectric is a certain solid material that can convert vibrations or deflection to become electrical energy. Five Piezoelectric pieces are arranged in two gearboxes and placed on the side of the ship to interact with ocean waves. Sea waves will move the synthetic buoy up and down so it also will trigger the movement of the rack gear at pinion which can make deflections on piezoelectric and produce electrical energy. This electricity will be stored in the accumulator or battery around 6-8 hour first. The result shows that this system will create 17.84 Wh to 22.12 Wh of energy. The electricity can be used for daily needs or commercialized. Thus, the authors expected that through this CAPTION who based on piezoelectric and ocean wave mechanism, these can fill up the electricity needs of traditional fishing communities while increasing the economy through the sale of electricity
