Implementation of lean manufacturing using waste assessment model model (WAM) in food industry (case study in usaha mikro kecil menengah (umkm) xyz)

Abstract

Abstract The waste occurring on the production line leads to inefficient production and loss to the company. Based on the results of brainstorming with UMKM XYZ owners, it is known that there is a reduction in the production time of up to 20% of the production time is 4 hours per cycle. The waste that occurs will be identified and minimized using methods of Waste Assessment Model (WAM) and Fault Tree Analysis (FTA) for proposed repairs. The purpose of the research is to calculate the percentage of waste and know the dominant waste, knowing the repair to minimize the largest waste, and calculating the amount of production time. The results showed that the dominant waste was the transportation of 17,09% with improvements was to change the layout of the production, change the design of tools, expand the production floor, implement a more integrated fixed contract system and minimize the production process. The average time that can be minimized for donut products, bread, and molen is 490 seconds per cycle or 8.167 minutes per cycle.
