PENGURANGAN PEMBOROSAN PADA PROSES PRODUKSI DENGAN MENGGUNAKAN WRM, WAQ DAN VALSAT PADA SISTEM LEAN MANUFAKTUR
A Multi-National Company located in Batam producing many types of iron. Some of its process is still using traditional way. This traditional process causes a lot of wastes. Cooling process is one of the processes that generate the most wastes. In order to reduce the waste, we implemented lean manufacturing concept. One of tool is Value Stream Mapping (VSM). This tool is used to explain the whole process from raw material to finish goods. By using Waste Relation Matrix (WRM) and Waste Assessment Questionnaire (WAQ) the waste is found due to exssessive Motion and to long Waiting. The root cause of this exssesive motion and long waiting mainly is because the process is not integrated and not flowing forward. The improvement was done by redesigning this cooling process lay out to became integrated line and providing carrier jig for product handling.
