Abstract
Penelitian ini mengkaji potensi torsi dan daya yang dihasilkan oleh pendulum dalam sistem Pembangkit Listrik Tenaga Gelombang Laut (PLTGL) tipe juring dengan variasi sudut kemiringan frame dan massa pendulum. Hasil penelitian menunjukkan bahwa torsi terbesar yang dapat dimanfaatkan adalah 1235,64 Nm pada sudut kemiringan frame 25°, massa 409,8 kg, dan sudut simpangan 175°. Pada sudut kemiringan frame yang berbeda, torsi yang dihasilkan bervariasi, dengan torsi maksimum masing-masing sebesar 999,99 Nm (20°), 756,73 Nm (15°), 507,71 Nm (10°), dan 254,82 Nm (5°). Potensi daya terbesar yang dapat dihasilkan tercatat pada sudut kemiringan frame 25°, massa 409,8 kg, dan sudut simpangan 175°, yaitu sebesar 12,82 kW. Potensi daya ini menurun seiring dengan penurunan sudut kemiringan frame, masing-masing menjadi 10,37 kW (20°), 7,8 kW (15°), 5,26 kW (10°), dan 2,6 kW (5°), dengan peningkatan potensi daya sebesar 1,2% hingga 2% setiap kenaikan sudut kemiringan frame. PLTGL ini terdiri dari komponen utama seperti poros, one way gearbox, planetary gear, flywheel, dan permanent magnet generator (PMG). One way gearbox dan planetary gear meningkatkan kecepatan putaran dengan rasio masing-masing 1:3 dan 1:27. Beberapa komponen tambahan diperlukan untuk optimalisasi sistem, termasuk plat shims untuk menaikkan poros, grip tracker sebagai penumpu torsimeter, dan sensor untuk membaca sudut simpangan pendulum. Gerakan pendulum yang dihasilkan menunjukkan pola sinusoidal dengan redaman optimal yang digunakan yaitu b’ sebesar 0,0003, b sebesar 0,45, dan k sebesar -1. Redaman ini disebabkan oleh gesekan antara poros pendulum dengan frame, gesekan bandul dengan udara, dan konversi energi melalui gear.

This study examines the torque and power potential generated by a pendulum in a Sector Double Pendulum Wave Energy Converter (PLTGL) system, considering variations in frame tilt angle and pendulum mass. The results indicate that the maximum usable torque is 1235.64 Nm at a frame tilt angle of 25°, a mass of 409.8 kg, and a deflection angle of 175°. At different frame tilt angles, the generated torque varies, with maximum torques of 999.99 Nm (20°), 756.73 Nm (15°), 507.71 Nm (10°), and 254.82 Nm (5°). The highest power potential recorded is at a frame tilt angle of 25°, a mass of 409.8 kg, and a deflection angle of 175°, yielding 12.82 kW. This power potential decreases with reduced frame tilt angles, measuring 10.37 kW (20°), 7.8 kW (15°), 5.26 kW (10°), and 2.6 kW (5°), with an increase in power potential of 1.2% to 2% for each increment in frame tilt angle. The PLTGL consists of key components such as a shaft, one-way gearbox, planetary gear, flywheel, and permanent magnet generator (PMG). The one-way gearbox and planetary gear increase rotation speed with ratios of 1:3 and 1:27, respectively. Additional components are needed to optimize the system, including shim plates to raise the shaft, grip trackers to support the torsimeter during torque measurements, and sensors to read the pendulum's deflection angle. The resulting pendulum motion shows a sinusoidal pattern with optimal damping values used, namely b' of 0.0003, b of 0.45, and k of -1. This damping is caused by friction between the pendulum shaft and frame, air friction on the bob, and energy conversion through gears.
