Abstract
In the piping industry, Butt Fusion machines are vital tools for connecting HDPE (HighDensity Polyethylene) pipes in water and gas distribution networks. Operational disruptions in these machines have the potential to cause connection defects and hinder production continuity. This study focuses on identifying the types of failures and their triggering factors in the Butt Fusion machines at PT. Panca Indah Jayamahe, as well as determining the optimal maintenance strategy to improve reliability through the Failure Mode and Effect Analysis (FMEA) approach. The research methodology includes collecting failure history data for the 2019-2024 period, implementing FMEA analysis to calculate the Risk Priority Number (RPN), and evaluating reliability based on the Weibull distribution using the Weibull++6 application. The calculations included several critical parameters such as the Probability Density Function (PDF), component reliability levels, failure rates, and Mean Time Between Failure (MTBF). The FMEA analysis findings indicated that the hydraulic seal was the component with the highest risk level (RPN 120), followed by the cutting component (RPN 90) and the heater (RPN 50). The reliability evaluation shows that the MTBF of the heater reaches 11,395.71 hours, the cutting component 10,340.52 hours, and the hydraulic seal 5,411.37 hours. The recommended preventive maintenance implementation at a reliability of R=0.8 is set at 9,918 hours for the heater, 9,634 hours for the cutting component, and 1,420 hours for the hydraulic seal. The study concludes that the implementation of the FMEA method has proven to be efficient in identifying high-risk components and setting maintenance priorities. A planned preventive maintenance strategy can minimize operational failures, reduce unscheduled downtime, and optimize the operational life of Butt Fusion machines. Keywords : Butt Fusion; FMEA; HDPE; MTBF
