The Company IM is a manufacturing company that produces two-wheeled automotive spare parts. One of the products currently being supplied to several two-wheeled customers is the disc brake, rear sprocket, and drive sprocket. The opportunity to increase production output adjusted to high customer demand can be done by reducing waste activities. Therefore, an approach with a lean six sigma approach is needed using the integration method of DMAIC (Define, Measure, Analyze, Improve, and Control), VSM (Value Stream Mapping), and VALSAT. This study aims to reduce production waste and reduce cycle time, affecting increasing production output to balance according to customer needs. Waste identification is explained in the Define stage at DMAIC using a big mapping image in Value Stream Mapping. A more in-depth analysis is carried out using the VALSAT tools at the Analyze stage supported by WRM and WAQ questionnaire data. The Analyze stage was then carried out by analyze using the FMEA method. Control is carried out by standardization and outreach to employees. This study aims to identify and reduce the waste in the production area, especially line-cutting disks. Based on the integration results of lean six sigma with the DMAIC, VSM, and VALSAT methods, the efficiency is obtained from 72% to 96%.

The primary purpose of this article is to present a maturity model dealing with environmental manufacturing processes in a company. According to some authors, Industry 4.0 is based on characteristics that have already been the focus of “lean and green” concepts. The goal of the article was to move from resource consumption, pollutant emissions, and more extensive manufacturing towards environmentally responsible manufacturing (ERM). Using environmental materials and methods reduces energy consumption, which generates cost savings and higher profits. Here, value stream mapping (VSM) was applied to identify core processes with environmental potential. This paper provides an understanding of the role of environmental manufacturing in the era of the Fourth Industrial Revolution.
