STUDI KASUS PENYEBAB KERUSAKAN LEVEL REGULATOR PADA LIFTING PUMP DI PT XYZ

Sensor is an electronic device that detects changes in physical quantities such as electricity, pressure, motion, force, light, temperature, humidity, and speed, and converts the input into an output that can be understood by humans. The sensor used by PT XYZ is the Flygt ENM-10 Level Regulator, which functions as an automatic system for a Submersible pump in distributing wastewater. One of the problems that occurred is damage to the Level Regulator. This damage has an impact on the distribution of wastewater, particularly because the Submersible pump relies on this sensor to regulate its operation. In the wastewater distribution system at SH Airport, each Lifting Pump is connected in a chain, so when a problem occurs with one Lifting Pump, it will affect the distribution of wastewater. This research identifies the damage to the Level Regulator using Root Cause Analysis with the Fishbone Diagram Methods. The results of the identification are used to determine the factors causing the damage to the Level Regulator. After finding the root of the problem, solutions are sought to address the issue, thereby, this research not only identifies the cause of the damage but also offers solutions to prevent the same problem from recurring.
