Proposal Improvement to Increase Equipment Effectiveness and Reduse Waste Levels in SME Plastic Straw Prodecer with a Total Productive Maintenance Approach and Waste Assessment Model

Abstract

The existence of waste in a production line causes production equipment and production systems to be ineffective and inefficient. It's the same with an SME that produces plastic straw products in a city in Indonesia. BNL50 machine that produces plactic straw, often experiences problems such as breakdowns and minor stoppages. Thus, the amount of total production is low and the delivery of customer orders is often delayed. The purpose of this study was to give improvement proposed to the company based on the equipment effectiveness and the significant waste. The method that used in this study is Total Productive Maintenance approach using Overall Equipment Effectiveness (OEE) and Six Big Losses, as well as identification of the most dominant waste in the production line using the Waste Assessment Model (WAM). The average value of the effectiveness of the BNL50 machine for four months calculated by OEE is 87.40% with reduced speed losses as the highest losses value which causes the low OEE value. With the WAM method, the highest value were found, that is waiting. Suggestions for improvement given to the SME company is implementing 5S and the pillars of TPM as well as making SOPs for operator training, material mixing composition, and machine hygiene standards.
