Identifikasi Kegagalan Komponen Harbour Mobile Crane Menggunakan Failure Mode and Effect Analysis di Perusahaan Jasa Bongkar Muat Petikemas

Abstract

Container terminals play a crucial role in driving the economy through the distribution of goods. The Harbour Mobile Crane (HMC) is the main equipment used in the container loading and unloading process, operating 24 hours a day to meet production targets. The high intensity of work makes HMCs susceptible to failures, which can disrupt operational activities and increase the risk of accidents. This study aims to identify and analyze the risk of HMC component failures using the Failure Mode and Effect Analysis (FMEA) method at a container stevedoring company. FMEA is used to identify failure modes, effects, and causes of failure for each HMC component. Each failure mode is assessed based on severity, occurrence, and detection to obtain a Risk Priority Number (RPN). Data were collected through expert judgment interviews, direct object observation, equipment failure records, and equipment manuals. The identification results of HMC components using the FMEA method show that out of 6 main components and 41 subcomponents analyzed, there is one subcomponent with the highest RPN value in each main component. The subcomponents with the highest RPN values include the fuel filter with a failure mode of clogged fuel filter and an RPN of 105, wire ropes with a failure mode of broken wire ropes and an RPN of 240, hydraulic system with a failure mode of hydraulic oil leakage and an RPN of 120, twist lock with a failure mode of broken twist lock and an RPN of 128, battery PLC with a failure mode of broken battery PLC and an RPN of 48, and joystick with a failure mode of joystick trouble and an RPN of 120. The identified failure modes, effects, and causes of failure for components with the highest RPN values can be used as a tool to determine recommendations for improvement.
