Abstract: This study aims to analyse waste on the production floor, causing delays in the completion of the production process and affecting product delivery to consumers. In addition, this research is also used to explain the types of waste and provide alternative improvements to reduce waste on the production floor using a lean manufacturing approach. Using the value stream mapping method, researchers mapped the flow of information and materials in the production process. Furthermore, the actual condition of the company is described in the current state stream map using the 5W-1H method of waste identification tool. This study found that there were a waste of defective goods in the frame, wastage in the weaving repair process and activities to find boxes and waste of transportation on the production floor. Implementing the proposed improvement is expected to reduce the waste that occurs to reduce the production lead time.
