Lean Thinking Approach to Waste Reduction in The Production Process At Transformer Companies

Abstract

Minimizing all waste (waste) is mandatory for the company. The results of the study using a lean approach, followed by looking at the winding process as a whole, Big Picture Mapping and identification of waste that occurs in business processes, carried out by comparing the actual time to the standard time for the winding process, the value-adding time for the winding process is 21310 minutes. In contrast, the total production time is about 22995 minutes. The non-value-adding time which does not add value to the product is 1685 minutes and identified the cause for the delay using Root Cause Analysis. Waste waiting is the most waste among other wastes.
