Water Cycle efficiency is very important in the operation of a Power Plant. The PLTU usually only counts on energy efficiency, as it is based on the first law of thermodynamics even though the method is deemed to be lacking in drawing important aspects of energy utilization, because it needs to be combined with an exergy approach based on the second law of thermodynamics to determine the accuracy of the magnitude of Power Plant efficiency. Therefore, the purpose of this research is to find out the energy efficiency and exergy of components before and after overhaul in the UJP Banten 1 Suralaya Water Cycle to determine losses in the Water Cycle so that improvements can be made. The method used is the method of calculating energy efficiency and exergy which is influenced by enthalpy and entropy. The results of the study show that energy efficiency and exergy efficiency have increased after overhauling and the destruction of exergy has decreased.} }
