N2  - Machines are a crucial component of production for companies in processing a
product. Even minor machine failures can have small to large impacts on the
production process and disrupt the stability of operations. PT. Pupuk Kujang is a
chemical company that produces chemical fertilizers such as urea and ammonia.
In this company, there are machines with high failure rates. There were 38
breakdowns recorded from 2020 to 2024, involving various components, causing
the production machines to be down for a total of 476 hours. This study aims to
determine the appropriate maintenance actions and maintenance intervals. Based
on qualitative data analysis using FMEA, six components were identified as having
the highest impact on machine failure, contributing to approximately 80% of the
issues. These components are the turbine servo motor, discharge valve, suction
valve, regulating valve, gasket deckle and oil seal regulating. These components
are the focus of the study. Using LTA and the RCM II decision worksheet, it was
found that the suction valve, discharge valve, gasket deckle, and oil seal regulating
components should undergo scheduled discard tasks, while the regulating valve
and turbine servo motor should be maintained through scheduled on-condition
tasks. Based on quantitative data analysis using the age replacement method to
determine reliability, it was found that maintenance for the turbine servo motor
should be carried out at 4,425 operating hours. The machine downtime percentage
significantly decreased after applying the age replacement method. Specifically, the
downtime reduction was 30,97%, for the turbine servo motor, 18,73% for the
discharge valve, 53,40% for the suction valve, 9,89% for the regulating valve,
gasket deckle 61,68%, and 56,29% for the oil seal regulating.
