WASTE ANALYSIS USING “9 WASTE” IN THE PRODUCTION PROCESS OF PT ABC
Keywords:Production, Waste, Lean
An effective and efficient production system will produce quality products, so the company does not experience losses. One of the losses experienced by a company is due to waste problems. This study aims to analyze the waste in the production of product X at PT ABC using the Lean approach. The classification results show that the overall production activity of each process obtained is 22% for value-added activities (VA), 22% for non-value-added activities (NVA), and 56% for required non-value-added activities (NNVA). From the results of the classification can then be identified in 9 factors that can cause waste. 9 Waste is abbreviated as E-Downtime, which is from Environmental, Health, and Safety (EHS), Defect, Over Production, Waiting, Non-Utilizing Employee, Transportation, Inventory, Motion, and Excess Processing. Based on the results of identification and analysis, the waste problem that occurs is that each operation process is completed, the trial object for product X will be measured by the QA, and the measurement is carried out repeatedly until the last operation. In addition, there is a queue from the QA side, causing quite a long downtime, as a result the production lead time will be longer. The proposed improvement recommended by the researcher is that the measurement of trial objects by the QA party is carried out simultaneously, namely once after the production process from the first operation to the last operation has been completed. This can minimize the production operator's idle time so as to eliminate waste at PT ABC.
