If a power plant uses a turbine as a means to transmit steam-containing energy into power that will turn a generator, then the generator is more commonly known as a steam turbine. Steam turbine is a starting drive that converts the potential energy of steam into kinetic energy and then converts it into mechanical energy in the form of turbine shaft rotation. The turbine shaft, directly or with the help of a reduction gear, is connected to the mechanism that will be moved. . At the Banten 2 Labuan PLTU, a turbine LP blade was damaged which caused efficiency to decrease. before the installation of LP Blade turbines, the load that can be achieved at a maximum load is only 280 MW while the maximum load according to the model is 300 MW. Turbine efficiency before turbine blade replacement is 77.92% after turbine blade replacement is 79.10%} }
