Abstract
Energi gelombang laut (wave energy) Salah satu sumber energi dari laut yang
dapat digunakan, salah satunya dengan pembangkit listrik tenaga gelombang
laut sistem pendulum ganda, salah satu komponen system tersebut adalah
system gearbox yang berfungsi mengkonversi energi dari gelombang laut untuk
di salurkan ke system setelah gearbox sebelum menuju ke generator. Sistem
gearbox ini berfungsi sebagai perubah arah dan kecepatan putaran sehingga
putaran yang bersifat fluktuatif dari gelombang laut tadi bisa menjadi searah
putarannya sehingga nanti bisa masuk ke generator sesuai dengan putaran
optimalnya, selain itu sistem gearbox ini juga bisa membantu mengatur
sedemikian rupa sehingga pengolahan energi setelah dari gearbox tidak sangat
terbebani akibat fluktuasi energi yang dihasilkan. salah satu pemanfaatannya
yaitu menggunakan oneway bearing dan memperhitungkan rasio roda gigi yg
di gunakan. Pada penelitian ini, dilakukan perancangan bagaimana agar
gelombang laut yang bergerak fluktuasi ini bisa menghasilkan energi yang
terarah yaitu dengan kombinasi oneway bearing serta rasio roda gigi. Adapun
untuk putaran dan torsi sebagai input awal diambil nilai maksimum dari
percobaan yang telah dilakukan agar desain yang dihasilkan dapat menerima
dampak ketika energi yang dihasilkan gelombang laut saat keadaan maksimal,
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 roda gigi yang digunakan dalam
perancangan ini yaitu 1:0,25 agar ketika energi dari gelomnbang lautnya berada
pada keadaan minimum roda gigi ini masih bisa meningkatkan putarannya
sehingga dapat memenuhi generator. sedangkan Diamater poros pendulum
sebesar 50 mm dan Diamater poros gearbox sebesar 65 mm, Bearing poros
pendulum memiliki design load 1882 N dan Bearing poros gearbox memiliki
design load 3541.3 N dan Coupling yang akan digunakan adalah rigid coupling,
dengan rated torque 18500 Nm.

Ocean wave energy (wave energy) One source of energy from the sea that can be used,
one of which is a double pendulum system ocean wave power plant, one of the
components of the system is a gearbox system which functions to convert energy from
ocean waves to be channeled to the system after gearbox before going to the generator.
This gearbox system functions as a change in direction and speed of rotation so that the
fluctuating rotation of the ocean waves can be in the direction of rotation so that later it
can enter the generator according to its optimal rotation, besides that this gearbox system
can also help regulate in such a way that energy processing after from gearbox is not very
burdened due to fluctuations in the resulting energy. One of the uses is to use a oneway
bearing and take into account the gear ratio used. In this study, a design was carried out
on how to make sea waves moving with fluctuations to produce directional energy,
namely a combination of oneway bearings and gear ratios. As for the rotation and torque
as the initial input, the maximum value is taken from the experiments that have been
carried out so that the resulting design can receive an impact when the energy produced
by ocean waves is at its maximum, 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 gear
ratio used in this design is 1:0.25 so that when the energy from the ocean waves is at a
minimum, this gear can still increase its rotation so that it can meet the generator. while
the pendulum shaft diameter is 50 mm and the gearbox shaft diameter is 65 mm, the
pendulum shaft bearing has a design load of 1882 N and the gearbox shaft bearing has a
design load of 3541.3 N and the coupling to be used is rigid coupling, with a rated torque
of 18500 Nm.
