Abstract

Energi terbarukan adalah energi yang dapat diperoleh ulang (terbarukan) dan bersifat kontinyu. Jenis energi terbarukan yang paling melimpah di Indonesia sendiri adalah energi gelombang. Alat yang digunakan untuk mengkonversi energi gelombang laut menjadi energi listrik sendiri ada banyak jenisnya. Salah satu alat yang mempunyai sistem sederhana yaitu PLTGL-SB (Pembangkit Listrik Energi Gelombang Laut Sistem Bandul) yang pertama kali dibuat oleh Zamrisyaf pada tahun 2010. Namun sampai saat ini belum ditemukan parameter bentuk ponton yang menghasilkan olah gerak paling baik untuk menghasilkan daya yang besar. Telah dilakukan eksperimen dengan menggunakan prototype 1:10 berbentuk silinder dengan cadik simetris di kedua sisinya untuk diperoleh parameter yang paling sesuai sehingga didapatkan gerakan pendulum dengan amplitudo yang besar untuk menghasilkan daya yang besar pula. Berdasarkan hasil eksperimen tersebut, diperoleh kesimpulan bahwa variasi yang menghasilkan simpangan pendulum paling besar yaitu ketika panjang lengan cadik 413 mm, tinggi cadik 40 mm, panjang lengan pendulum 106.7 mm, massa pendulum 20 gram, dan periode gelombang 0.8 detik dengan simpangan pendulum maksimum sebesar 60 derajat.

Renewable energy is kind of energy that can be obtained repetitively and tend to be continuous. One type of renewable energy that overflow in the world is ocean wave energy. The devices that used to extract ocean wave energy into electrical energy is called WECs (Wave Energy Converters). Recently, there are many kind of WECs that already developed by engineer. Ocean wave power plant based on pendulum system is one type of the WECs that has simple ways of working. The first man who invented this device is Zamrisyaf at 2010. But until today, the researcher still haven’t found the parameter of pontoon geometry that can afford a good seakeeping for this WECs. In this work, the research of the ocean wave power plant based on pendulum system has been performed using experimental investigation. The aim of this study is to analyze the novel geometry of pontoon that identical to trimaran that can produce large ampitudo of pendulum oscillation through experimental approach. The analyzed aspect are the combination of outrigger length, outrigger height, pendulum rod length, pendulum mass, and wave periods which have maximum amplitude of pendulum oscillation. The experimental results shown that the best combination is pontoon thus has outrigger length of 413 mm, outrigger height of 40 mm, pendulum rod length of 106.7 mm, pendulum mass of 20, and wave periods of 0.8 s which have maximum amplitude of pendulum oscillation as big as 60 degrees.
