Abstract

Work design that involves waste will negatively impact the performance results. This waste can be identified using the Lean 3M method (Muda, Muri, Mura). Muda refers to waste, which is defined into seven types of waste, including overproduction, excessive processing, unnecessary transportation, excessive motion, inventory, waiting time, and defects. Muri refers to overload, which is the result of eliminating too much Muda from the process. An operator or machine is considered overloaded when used more than 100% to complete a task. Mura refers to imbalance, which can be found in fluctuations in customer demand and variations in cycle time for different operators. The unit of measurement used to assess performance is the standard time. Standard time is obtained by multiplying normal time by allowance. Normal time can be measured using the MOST method. The results of this study include the following time savings: 68.904 seconds (13.0435%) on the setup phase, 40.392 seconds (4.43864%) on “moving bundles to pallet” operation, 0 second (0%) on “cleaning slotter debris" operation, 118.8 seconds (21.3675%) on the inspection operation, and 45.144 seconds (45.7831%) on the feeder operation.
