PT Dirgantara Indonesia ia a state-owned company that runs aircraft manufacturing industry. In order to operate normally, PT Dirgantara Indonesia have several production divisions. One of the most important production division, detail part manufacturing have many departments, such as tool manufacturing & service department. The purpose of this department is to create supporting tools for other department’s job, such as fixture. Work system that used in this department based on order system. By using order system, order is distributed from leader to operator in order to start the task. One of the problem that happenened in this department is the order cannot taken directly by the operator. So, lead time that needed to finish this order become longer. There are many factors that make this problem happened, such as unbalanced operator’s skill and improper placement of work piece. Lean Manufacturing will be used in order to solve this case. With the Lean Manufacturing, the actual condition will be maped into Value Stream Mapping. After mapping process, the next activity is finding the root cause of waste by using 5 Whys Method. root causes that found after using this method is unbalanced workload, unbalanced operator’s skill, and finding tools problem. After that, improvement recommendation created based on the root cause. Method that recommended for improvement recommendation are workload distribution, competence training, and 5S principles (seiri, seiton, seiso, seiketsu, shitsuke). By using workload distribution, time that needed for components to waiting before processing reduce to ten days. Competence training can reduce processing time in Work Stations Jig Assy and Fitter Dies Tool to 10%. When using 5S principles, time that needed for finding movement reduced to 80%. So, the operator can start the task quicker.
