Abstract

Krisis energi bukan lagi hal yang baru di Indonesia, Sehingga banyak pemikiran tentang pengembangan energi alternatif. Beberapa pengembangan telah dilakukan, seperti teknologi micro hydro, bio mass, energi matahari, dan energi laut. Dari beberapa energi alternatif yang ada, energi laut merupakan potensi yang perlu dikembangkan mengingat Indonesia adalah negara kepulauan dengan garis pantai terbesar kedua setelah kanada. Dengan demikian perlu dilakukan penelitian tentang energi laut. Pada penelitian ini dilakukan proses modeling dan simulasi pada pembangkit listrik tenaga gelombang laut tipe kayuh dayungpiezoelectric. Prinsip kerja dari mekanisme pembangkit listrik tenaga gelombang laut ini adalah dengan memanfaatkan energi kinetik dari gelombang laut. Pada saat gelombang laut menyentuh permukaan dayung, maka dayung akan bergerak dan batang dayung akan mengungkit penggerak, sehingga poros pendorong akan bergerak secara horizontal dan kemudian menyentuh piezoelectric. Gaya dorong yang diberikan poros pada piezoelectric akan membuat piezoelectric terdefleksi, defleksi dari piezoelectric tersebut akan menghasilkan energi listrik berupa voltase, arus listrik dan daya listrik. Dengan memvariasikan frekuensi gelombang laut (0.8 Hz, 1 Hz, 1.2 Hz), tinggi gelombang laut (0.04 m, 0.05 m, 0.06 m),, dan jumlah piezoelectric (10, 20, 30) maka karakter energi yang dihasilkan piezoelectric dapat dipelajari. Setelah melaksanakan pemodelan dan simulasi tentang PTLGL sistem kayuh dayung- piezoelectric, didapatkan hasil respon voltase maksimum sebesar 6.42 V didapatkan pada frekuensi 1.2 Hz, 6 cm tinggi gelombang dan 30 piezoelectric, untuk voltase minimum sebesar 1.24 V didapat pada frekuensi 0.8 Hz, 4 cm tinggi gelombang, dan 10 piezoelectric. Untuk arus listrik maksimum sebesar 20 mA didapatkan pada frekuensi 1.2 Hz, tinggi gelombang 6 cm, dan 10 piezoelectric, sedangkan hasil minimum sebesar 0.9 mA didapatkan pada frekuensi 0.8 Hz, 4 cm tinggi gelombang, dan 30 piezoelectric. Daya listrik maksimum sebesar 42 mW didapatkan pada frekuensi 1.2 Hz, tinggi gelombang 6 cm dan 10 piezoelectric, sedangkan daya minimum sebesar 1.4 mW didapatkan pada frekuensi 0.8 Hz, 4 cm tinggi gelombang dan 30 jumlah piezoelectric ================================================================================================================== Energy crisis is not a latest issue in Indonesia, therefore a lot of idea about alternative energy had been developed. A few of developed alternative energy such as micro hydro technology, bio mass, solar energy, and ocean wave energy. Of which there are several developed alternative energy, ocean wave energy is the most potential energy source to be seriously developed considering that coastline of Indonesia is the second largest after Canada. Thus, it is necessary to be researched. Modeling and Simulation are executed in this research of swing paddle-piezoelectric ocean wave power plant. The mechanism of swing paddle-piezoelectric ocean wave power plant utilize the ocean wave kinetic energy. When the wave graze the paddle surface, the paddle moves so that the paddle rod swings. After the paddle rod swings, then the mass mechanism moves. Since the mass mechanism moves horizontally, the contact surface between mass mechanism and piezoelectric occur, which the applied axial force deflects piezoelectric within. Hence while the piezoelectric is deflected, the electrical element of the piezoelectric generates electrical energy in the form of voltage, current and electric power. By varying the frequency of the ocean waves ( 0.8 Hz , 1 Hz , 1.2 Hz ) ,the high of ocean waves ( 0:04 am , 0:05 am , 0:06 am ) , and the number of piezoelectric ( 10, 20 , 30 ), the energy characteristic generated by the piezoelectric can be learned . After the modeling and simulation of swing paddle-piezoelectric ocean wave power plant are executed. The response of maximum voltage reached is 6.42 V, when 1.2 Hz of wave frequency, 6 cm of wave height and 30 of piezoelectric. The minimum voltage achieved is 1.24 V, when 0.8 Hz of wave frequency, 4 cm of wave height and 10 of piezoelectric. The maximum current reached is 20 mA, when 1.2 Hz of wave frequency, 6 cm of wave height, and 10 of piezoelectric. The minimum result of current is 0.9 mA, attained when 0.8 Hz of wave frequency, 4 cm of wave height, and 30 of piezoelectric. The maximum electrical power reached is 42 mW, when 1.2 Hz of wave frequency, 6 cm of wave height, 10 of piezoelectric. In other hand the minimum electrical power attained is 1.4 mW, when 0.8 Hz of wave frequency, 4 cm of wave height, 30 of piezoelectric.
