ABSTRAK

Pendayagunaan energi gelombang air laut pertama kali dilakukan oleh Bapak Zamrisyaf SY dari Badan Penelitian dan Pengembangan Ketenagalistrikan PT Perusahaan Listrik Negara persero. Konsep rancangannya diberi nama PLTGLSB atau Pembangkit Listrik Tenaga Gelombang Laut Sistem Bandulan. Pengembangan pembangkit listrik tenaga gelombang laut ini memerlukan proses akselerasi sehingga diperlukan proses scale-up melalui peningkatan kapasitas daya PLTGL-SB menjadi 20 KW kiloWatt. Dengan memberikan desain ponton yang sederhana dapat mengakomodir penilitian ini. Sistem dibatasi hanya pada gerak pitching. Dengan menggunakan persamaan Lagrange maka didapat dua persamaan gerak yang digunakan dalam penelitian ini. Terdapat tiga variasi untuk menentukan kontinuitas gerak bandul. Variasi tersebut adalah variasi periode gelombang variasi panjang lengan bandul dan variasi tinggi tiang penyangga bandul. Massa bandul yang digunakan tidak melebihi dari 48 1 kg karena hal ini membuktikan gerakan bandul yang hampir tidak ada. Semakin besar periode gelombang yang mempengaruhi gerakan ponton juga membuat semakin besar sudut simpang bandul yang terjadi. Oleh karena itu direkomendasikan sistem dikondisikan dengan periode delapan detik panjang lengan bandul 0.25 dari panjang ponton massa bandul 0.09 massa ponton dan tiang tinggi penyangga bandul sebesar 1.15 dari tinggi ponton.


ABSTRACT

Utilization of ocean wave energy was firstly performed by Mr. SY Zamrisyaf from the Electricity Research and Development State Electricity Company Persero. The concept design was named PLTGL-SB or Ocean Wave Power Plant Pendulum System. Development of ocean wave power plant need processing of acceleration so that the necessary process scale-up through increased capacity PLTGL-SB to 20 KW kilowatt. By providing a simple pontoon design can accommodate this research. The system is limited to the pitching motion. By using the Lagrange equation obtained two equations which is used in this research. There are three variations to determine the continuity of pendulum motion. Such variations are wave period the length of the pendulum arm and high of poles pendulum. Pendulums mass does not exceed of 48 1 kg because the pendulum movement is almost non-existent in this condition. The bigger wave period not only give affect of pontoon motion but also makes the greater angle of intersection of the pendulum. Therefore the recommended system is conditioned by a period of eight seconds the length of the pendulum arm 0.25 of pontoons length pendulum mass 0.09 of pontoon mass and high pendulum pole at 1.15 of the high pontoon.
