Electrolytic tinning line maintenance design using fuzzy risk-based maintenance method

Machines have an important role in maintaining production performance to produce according to the initial plan. Failure of machine operation will impact hampered production, adding raw materials to increased production costs due to rework or additional production. This study aims to analyze the potential risk of failure of the electrolytic tinning line machine. This study uses the fuzzy risk-based maintenance method, which is used to overcome uncertainty in determining the priority of components of the risk-based maintenance method. The results of data processing using risk-based maintenance show that the pump has an RPN value of 192. Data processing uses fuzzy risk-based maintenance with a pump component with a value of 500, which is included in the high category. The potential for failure is caused by the full B14 pump so that it cannot blow down, causing the effect of a solution queue. Maintenance design using routine maintenance, predictive maintenance, and preventive maintenance is expected to increase the reliability of the B14 pump.
