ANALISA PENYEBAB KERUSAKAN MESIN UNTUK MEMINIMALISASI DOWNTIME PADA MESIN GILINGAN DENGAN MENGGUNAKAN FUZZY FMEA (PT.SUKSES MANTAP SEJAHTERA)

This study aims to analyze the causes of damage to the milling machine. The data used in this research is based on real field data. Methods of data collection using questionnaires and direct interviews with employees and workers in the machine maintenance section. Analysis of the risk of causing damage using the fishbone diagram method, Failure mode and effect analysis (FMEA) is used to indicate problems that may exist in a system and determine actions for control and quality improvement in terms of preventing failures in a process or product. Fuzzy is used to support the decisions generated by Failure mode and effect analysis (FMEA) by calculating the crips value using systematic formulas. Based on the results of data analysis carried out using Fuzzy FMEA, the sub-machine with a risk of causing engine damage is the plunger holder with an FRPN value of 800
