For in Southeast Sulawesi today, there have been several types of power plants. The plants are diesel power plants, steam power plants, and gas power plants. Of all existing plant types, the whole depends on fuel usage derived from millions of years of fossil burning of coal and oil. All of these existing plants, of course, raise some of the good issues on the environment, health and the economy. To anticipate this matter, an effort is made with the provision of alternative electric energy fuel that is non-conventional nature of sea wave power plant. This ocean wave power plant uses oscillating water column technology (PLTGL-OWC). Wave energy is a renewable energy and environmentally friendly, and is always available at all times.

In this study we analyze the amount of energy generated by ocean waves by using oscillating water column (OWC) technology by varying the number of blades (4.5 and 6 pieces) on the turbine to be used also the column diameter of OWC design by simulating using ANSYS program 16.00 .

From the simulation results obtained that the maximum pressure occurs in turbines with the number of blades 6 of 90.017 Pa and the lowest pressure on the number of blade 4 pieces of 7.083 Pa. From the visualization, the flow pattern that occurs when passing turbine and stream line from airflow passing turbine shows that there is a lot of backflow on the back side of blade turbine with blade number 6 causing increased flow rate. As a result of increased flow velocity, the turbine rotation also increases so that the power generated also increases.
