Abstract
Perkembangan teknologi pada saat ini yang semakin pesat dan persediaan energi fosil mulai menipis seiringnya waktu dan kebutuhan yang semakin meningkat mendorong manusia untuk menciptakan inovasi terbaru dan mencari energi alternative yang dapat diperbaharui dan ramah lingkungan. VIVACE (Vortex Induced Vibration Aquatic Clean Energy) adalah sebuah alat yang cocok dengan perairan yang memiliki kecepatan arus rata-rata 0.257-2.57 [m/s] atau 0.5-5 [knot]. Dalam penelitian ini dimaksudkan untuk mengetahui udara bertekanan yang
dihasilkan oleh linear compressor dari persamanaan matematis dengan inputan gaya lift yang dihasilkan dari oscillating part berfungsi sebagai penggerak awal piston pada linear compressor sehingga gaya lift tersebut dikonversikan ke piston pada sistem linear compressor agar menghasilkan suatu aliran fluida bertekanan. Adapun variasi terhadap gaya lift, kecepatan aliran fluida pada oscillating part, dan penentuan konstanta pegas. Dari hasil penelitian didapatkan bahwa kecepatan (frekuensi) mempengaruhi besaran gaya dan tekanan yang dihasilkan pada sistem linear compressor, jika frekuensi bernilai semakin besar maka sebanding dengan nilai kecepatan dan percepatan menjadi lebih besar sehingga gaya yang dihasilkan bernilai besar dan sebaliknya. Besaran gaya sebanding lurus dengan besaran tekanan. Pada perhitungan tekanan total yang dihasilkan pada piston memenuhi syarat untuk membuka valve discharge, valve akan membuka apabila tekanan pada valve lebih kecil dari nilai tekanan pada
cylinder.

Nowadays, developing of technology is rapid progressively and fossil fuel is diminish sharply as time goes by and needs are increasing that makes human create new innovations and find out the alternative which is renewable and eco-friendly. Vortex Induced Vibration Aquatic Clean Energy (VIVACE) is a suitable instrument in average current waters 0.257-2.57 [m/s] or 0.5-5 [knot].
The purpose this research is to determine pressurized air which is produced by a linear compressor from equation with lift force input produced by an oscillating part
which functions as an initial piston driver in linear compressor so that lift force converted to piston in linear compressor in order produces a pressurized fluid current. There are variety of lift force, velocity of fluid current in oscillating part, and determination of force constant. The conclusion from this research is obtained, velocity (frequency) effects forces and produced pressure on linear compressor, if frequency is
higher, it is equal to velocity and acceleration which also becomes higher so the produced force is also high and otherwise. The magnitude of force is proportional to the amount of pressure. In the calculation of the total pressure generated on the piston is eligible to open the valve discharge, the valve will open when the pressure on the valve is less than the pressure value on the cylinder.
