Implementation of Lean Manufacturing for Increasing the Quality of Aluminum Conductor Products in the Stranding Process with the DMAIC and VSM Method Approach: A Case Study in Electrical Manufacturing Component

Abstract

Electrical Company in this study is a manufacturing company engaged in the cable industry and one of the products it produces is an aluminum conductor. The current situation shows that the quality of aluminum conductor products still does not meet the company's standards. This can be seen from the production output data for the period June 2021 – November 2021 where the percentage of aluminum conductor product failures exceeds the set target of 1.50%. The purpose of this research is to implement lean manufacturing to improve the quality of aluminum conductor products using the DMAIC (Define, Measure, Analyze, Improve, Control) and VSM (Value Stream Mapping) methods. The expected result of this research is an increase in product quality.
