Lean manufacturing implementation using value stream mapping to eliminate seven waste in painting process

Abstract

Gas stove producers faced intense competition in the market. This condition encourages gas stove producers to increase productivity by reducing 7 (seven) waste in the production process, especially in painting process. The purpose of this study is to determine the factors that can affect the reduction of 7 (seven) waste in the production process, knowing the number of Value Added (VA) and Non Value Added (NVA) in the reduction of 7 (seven) waste. The method used to identify waste is the Value Stream Mapping, for analysis of repairs used 5W 1H tools. VSM can provide a description of the material flow, and information during the production process, starting from the arrival of raw materials from suppliers to the delivery of finished products. From the calculation, a decrease in lead time by 1098.3 seconds and a decrease in NVA of 332.3 seconds were obtained.
