Abstract
Hydro energy is one of the potentials of renewable Energy in Indonesia. Indonesia has a vast sea, in the amount of 3,544,743.9 km2 making Indonesia a suitable country to utilize Oscillating Water Column (OWC) type power plants. The study was conducted to determine the effect of column diameter on the performance of OWC devices, especially in speed and dynamic pressure. There are 5 variations of the diameter of the column studied, namely 0.5 m, 0.75 m, 1 m, 1.25 m, and 1.5 m. Plus there are also variations in the wave period, namely 3s, 4s, and 5s. The result of this study is the column diameter of 0.75 m has an average speed of 0.389 m/s and a dynamic pressure of 2.676 N/m2, making it the best column diameter ratio of the five column diameter ratio options available.
