The Implementation of the Lean Thinking Concept for Reducing Waste: A Study Case in the Leather Tanning Process

摘要

The company is always trying to improve its excellence to compete with other companies engaged in the same field. The reducing waste is to increase of these advantages. During the production process waste occurs, including product defects, waiting, and transportation. Lean thinking is an approach that aims to streamline the process by reducing waste that occurs in the production process flow. The investigation on the cause of the waste is by using a diagram of cause and effects. Once the cause is known, efforts are made to improve the cause of the waste that occurs. The use of VALSAT tools, detailed mapping, and value stream mapping for improvement efforts will be made by making current state mapping and future state mapping. After obtaining an overview of future state mapping, a simulation is performed to create a simulation model based on the current situation and after repairs.
