lateness in repairing the machine and delay due to finding the mechanical and tools needed.
Furthermore, there is waste in maintenance activities because of the excess inspection
activities. Next the Sustainability Index (SI) is calculated and the SI value is 91.97% which
indicates that the company needs to make improvements to achieve the company target.
Analysis is carried out to get suggestions for improvements related to the problems that occur
and enhancing sustainable maintenance performance by making of the Future SustMVSM.The proposed improvement are applying 5S method in component storage activities
and tools needed for maintenance activities, pokayoke approach in monitoring the machine
and also doing practical training about lean maintenance and sustainable for production and
maintenance operator.
