This power plants has several main components, such as a steam turbine. The steam turbine is the main component that functions to convert the kinetic energy of the steam into mechanical energy from the resulting rotation. Steam turbines are not always operating at their maximum and efficieny measurements always need to made. This efficiency calculation is carried out to determine the work of the steam turbine when it operates. Component efficiency calculations are often performed during performance tests with varying loads before and after the overhaul is carried out. Overhaul is one of the planned maintenance activities. This overhaul activity is carried out for testing, maintenance, and repair of power plant components. Calculation analysis and efficiency comparisons are carried out to determined the condition of the components when the power plant operates. The comparisons of the efficiency value of the steam turbine was carried out to determine the condition of the turbine and the effect of the overhaul on the turbine.} }
