Abstract
Salah satu komponen utama dalam pembangkit listrik tenaga gelombang laut – sistem pendulum adalah sistem transmisi sebagai penyalur daya dan putaran ke generator. Sistem transmisi ini berfungsi sebagai perubah kecepatan putaran sehingga putaran yang masuk ke generator sesuai dengan putaran optimalnya, selain itu sistem transmisi ini juga dapat dimanfaatkan sebagai penstabil putaran akibat fluktuasi daya yang dihasilkan. salah satu metode penstabil putaran adalah dengan memanfaatkan roda gila. Pada penelitian ini, dilakukan perancangan kombinasi antara planetary gear sebagai peningkat kecepatan putaran dengan roda gila sebagai penstabil putaran. Adapun untuk putaran dan torsi sebagai input awal diambil nilai maksimum dari percobaan yang telah dilakukan, untuk putaran input sebesar 5 rad/s sedangkan untuk nilai torsi sebesar 650 Nm. Spesifikasi generator berkapasitas 3 Kw berjenis permanent magnet generator dengan putaran 550 rpm dan torsi 60 Nm. Rasio planetary gear yang digunakan dalam perancangan ini masing-masing sebesar 3.394 dengan dua tingkat agar dimensi planetary gear lebih kecil. Sedangkan untuk roda gila disambung dengan kopling dan bearing satu arah, dan diposisikan setelah planetary gear sehingga perencanaan roda gila menggunakan nilai output dari planetary gear. Didapatkan spesifikasi roda gila dengan massa 3,237 Kg, diameter 300 mm dan ketebalan 29,587 mm. Roda gila dengan spesifikasi tersebut memiliki momen inersia sebesar 0,07307 Kg/m2 dan mampu menyimpan energi kinetik sebesar 120,996 Joule.

One of the main components in the ocean wave power plant - the pendulum system is the transmission system as a distributor of power and rotation to the generator. This transmission system functions as a change in rotational speed so that the rotation that enters the generator is in accordance with its optimal rotation, besides that this transmission system can also be used as a rotation stabilizer due to fluctuations in the generated power. One method of stabilizing rotation is to use a flywheel. In this study, a combination of planetary gear was designed as an increase in rotational speed with a flywheel as a rotation stabilizer. As for the rotation and torque as the initial input, the maximum value is taken from the experiments that have been carried out, for the input rotation it is 5 rad/s while the torque value is 650 Nm. The specification of the generator with a capacity of 3 kW is a permanent magnet generator with a rotation of 550 rpm and a torque of 60 Nm. The planetary gear ratio used in this design is 3,394 each with two stages so that the dimensions of the planetary gear are smaller. While the flywheel connected by clutch and one way bearing and is positioned after the planetary gear so that the flywheel planning uses the output value of the planetary gear. The flywheel specifications are obtained with a mass of 3,237 Kg, a diameter of 300 mm, and a thickness of 29,587 mm. The flywheel with these specifications has a moment inertia of 0,07307 Kg/m2 and is capable of storing kinetic energy of 120,996 Joules.
