Lean manufacturing integration in production processes.

Study case in the research is a company engaged in automotive manufacturing that produces radiators. This year, there has been an increase in the demand for radiator production where company has not been able to meet this demand with the current condition of the production line, especially in the Styrofoam section. Therefore, it is necessary to have a Lean Manufacturing approach to increase productivity by reducing waste (waste). The method used is DMAIC (Define, Measure, Analyze, Improve, Control) and Value Stream Mapping (VSM). The flow of current state values is generally shown through Current State Mapping (CSM). Processing Based on the data, the Inner DMAIC is obtained, and the types of waste accepted are Over process. Next, the root causes of waste use the Fishbone Diagram and determine the appropriate improvement solution proposal using 5W+1 H tools. After that, make a comparison before and after repairs. And it can be seen through the flow of future condition values of FSM (Future State Mapping) so that there is a decrease in the production of cutting thick Styrofoam materials with cycle times from 614 seconds to 534 seconds and repeated reductions to 1 work step in the process of cutting thick materials.
