Abstract
PT. Max Power Indonesia Sorong is a power plant company that supplies the electricity needs of the City and Regency of Sorong with capacity 33 MW . However, in reality, the power that can be sold to PLN is around 20 MW per day on average or only 60 % of the total power that must be generated. This research was conducted to determine the value of the effectiveness of the generator engine and its causes. The analysis of the effectiveness of the generator engine was carried out using the calculation of Overall Equipment Effectiveness (OEE). Based on the OEE value, then we calculated the losses which resulted in the machine being ineffective. Furthermore, identifying problems based on losses using the Failure Mode and Effect Analysis (FMEA) method. The results of the analysis show that the overall engine effectiveness is 44.42%, based on the analysis of losses using the FMEA method, it is known that the sources of losses are idling and minor stoppage losses as the largest losses for 34,009.81 hours, setup and adjustment losses for 6,766,96 hours and breakdown losses for 3,736.97 hours. Meanwhile, exhaust gas temperature deviation from average value high is the biggest cause of all failure in the generator engine.
