Abstract

Sumber energi terbarukan menjadi pilihan yang sangat baik selain karena ramah lingkungan sumber dayanya juga melimpah. Salah satu sumber energi terbarukan berasal dari laut, energi gelombang laut sangat berpotensi untuk diekstraksi secara berkelanjutan. Alat yang mengubah energi laut menjadi energi listrik disebut dengan Wave Energy Converters (WECs). Pada penelitian ini, akan dilakukan analisa respon gerak terhadap ponton berbentuk katamaran yang memiliki dua pendulum, dengan harapan memiliki gerakan yang dapat mengikuti permukaan gelombang laut, sehingga dapat melakukan ekstraksi energi secara terus menerus dan menghasilkan energi yang lebih besar. Dari simulasi tahap pertama untuk melihat pengaruh parameter gelombang terhadap ponton, didapatkan nilai simpangan ponton terbesar pada variasi ke 44 dengan amplitudo gelombang 0.60 meter dan periode 7 s sebesar 88.721°. Sedangkan pada simulasi tahap kedua untuk melihat pengaruh pitching ponton terhadap simpangan pendulum, didapatkan nilai simpangan pendulum terbesar pada variasi ke 53 dengan amplitudo gelombang 0.6 meter dan periode 7 s, serta panjang lengan pendulum 1.5 meter dan massa beban 152 kg sebesar 10275° atau mengalami sebanyak 27.777 kali putaran. ================================================================================================================== Renewable energy are an excellent choice besides being environmentally friendly, the resources are also abundant. One of the renewable energy sources comes from the sea, ocean wave energy has the potential to be extracted sustainably. Devices that convert ocean energy into electrical energy are called Wave Energy Converters (WECs). In this research, an analysis of motion responses to catamaran-shaped pontoon having two pendulums is expected to have movements that can follow the surface of the ocean waves, so that they can extract energy continuously and produce more energy. The first simulation intend to see the effect of wave parameters on the pontoon, the largest pontoon pitching value is obtained in the 44th variation with 88,721°. The second simulation intend to see the effect of pontoon pitching on the pendulum deviation, the largest pendulum deviation value was obtained in the 53rd variation with 10275° or as much as 27,777 lap times.
