Abstract:
To improve manufacturing process to increase automobile parts manufacturers capacity in the long-term. Is to reduce waste in production processing by using Value Stream Mapping and to improve production process by using Kaizen based on Lean System, which will lead to increase of production efficiency and production cost reduction. The research found that to improve production processing contributes to decrease work in process 61.99%, 7.27% reduction of working area, 44.20% reduction of processing lead-time, 67.22% reduction of stock lead-time, 36.99% reduction of information lead-time. Moreover, efficiency of production process, which makes up 19.14%. It causes 25.07% increasing in productivity. Before improving manufacturing process, non value added of August in 2011 is 23.17 hour. After that, researchers apply Kaizen for production development. The result is 9.695 non value added or 58.16%. In August 2012, 38.18 hour of non value added reduce to 22.49 hour or 41.09%. After the improvement. I therefore conclude that, Kaizen based on lead system, reduces cost reduction of production efficiency.
