Abstract
The Mulyo Jati Farmers Group^s milk chocolate products are among the products with high demand among the candy types. However, in the production process of milk chocolate within 1 year, it was known that there was damage to production machines, especially vertical tempering machines, ball mills, and stone mills. This causes the production process to stop for 1 to 2 weeks with effect in decreased machine efficiency and effectiveness. This study aims to determine the level of effectiveness of the milk chocolate production machine as well as to identify losses that occur in the milk chocolate production system.
In this study, the Overall throughput effectiveness (OTE) method will be applied to the problem of machine effectiveness. The analysis was continued using the Failure Mode Effect and Critically Analysis (FMECA) method. The results showed an OTE value of 78.89%. The priority of the machine repair strategy is based on the criticality analysis of the high category, namely damaged steel balls on the BMV-10 ball mill machine. While in the medium criticality category, the oil runs out in the vertical tempering machine. The improvement strategy for high failure is determining the quality standard of cocoa beans, rejecting cocoa beans that do not meet the standard, and training for assisted farmers. Another improvement strategy that can be done by the Mulyo Jati Farmers Group is implementing preventive maintenance.
