Universitas Brawijaya Electrical Engineering (TEUB) carved another achievement on the 2018 Indonesia Energy Innovation Challenge event held by the Hasanuddin University Mechanical Engineering Student Association on November 21-23 2018.

This time the team, led by Kevin Rachman Firdaus and two of his colleagues Ariq Kusuma Wardana and Mohammad Mufti Fajar managed to grab the second place with a work entitled CAPTION (Cantilever Piezoelectric Energy Harvester with Energy Bank System for Fisherman) as an Alternative for Technological Innovation in Utilizing Maritime Energy Sources.

One of the team members, Ariq revealed that the creation of this work was motivated by the lack of even distribution of electrification in coastal communities which caused a gap and a decline in welfare for fishermen. Electronic devices that should help make it easier for fishermen, but because of the lack of electricity supply, it adds new problems.

"For example, there is a fish fridge that is converted into a clothes closet. In addition, the government also realizes that coal-based electricity generation needs to be revised so that the use of Renewable Energy needs to be utilized," he said.

CAPTION seeks to offer alternative solutions by utilizing ocean waves and piezoelectric cantilever. Piezoelectric is an energy generator that comes from vibration and is converted into an electrical voltage. The cantilever system produces repeated vibrations and deflections. This system produces electricity that is cheap and easy to apply.

This tool is in the form of a gearbox that is placed on the left and right side of the ship containing buoys, gear mechanisms, blades, and piezoelectric cantilever. In addition, this tool is also equipped with energy storage in the form of accumulators to become energy harvester. Mufti added, from the survey results it was found that fishermen generally sailed for 6-8 hours so that with that duration, fishermen were able to produce energy of 17.84 Wh - 22.12 Wh. This energy can be increased if it is developed in terms of its piezoelectric quality and quantity, increases the quantity of piezoelectric deflection and the duration of energy storage.

Followed by 40 participants from 14 teams from all over Indonesia, the CAPTION team was able to attract the attention of the jury of the Ministry of Energy and Mineral Resources with a fairly simple but significant impact on tools and mechanisms. The jury revealed that this tool could be an alternative solution to the problem of electrification for coastal areas because compared to complex generators, this tool is quite easy and simple when applied to fishermen. Moreover, this tool is quite economical, because it only costs Rp. 950,000.

Under the guidance of Eka Maulana S.T., M.T., M.Eng., The tool in the form of a prototype was prepared for approximately 2 months but was able to provide satisfactory results. "Hopefully in the future, this tool will be able to find the right components through several tests. Moreover, the CAPTION team hopes for various collaborations that support research so that it is ready to be applied to fishermen on all beaches in Indonesia," hoped Team Leader, Kevin.
