Abstract
The main purpose of this study is to increase the Overall Equipment Effectiveness (OEE) of the machine by using scheduled maintenance on conveyor belts machine in the receiving-distribution room (company case study). Production efficiency can be increased by reducing the loss from the production process. The historical maintenance data shows that the maintenance method for the case study machine was breakdown maintenance, which affects the production system due to the loss of production capacity, caused by the downtime. Therefore, the producer begins with a plan to change spare parts early and re-engineer the machine’s components to improve their useful life. Additionally, a machine check sheet was designed, and equipment as designed to help reduce waste from the raw material distribution process. After implementation, the results show the Overall Equipment Effectiveness (OEE) increased by 4%, from 75% to 79% (it could also increase the Meantime Before Failure (MTBF) and Mean Time to Repair (MTTR) as well). The specially designed machine components were installed to prevent raw materials from falling from the conveyor, which can reduce the amount of waste from the production process. In addition, the installation is divided into 2 parts. Firstly, installation of cleaning brushes can reduce waste by 91.82%, from an average of 5.50 kilograms per day, to an average of 0.45 kilograms per day. Secondly, the installation of a raw material supporting plate can reduce waste by 93.75%, from an average of 1.60 kilograms per day to an average of 0.10 kilograms per day.
