Abstract

The increasing of the air cleaner’s production cost was one of the problems experienced by PT. Astra Otoparts Adiwira Plastics Division. The production costs consist of three types of the cost, namely cost of materials, labor costs, and factory overhead cost. The increasing of production cost is caused by the large number of manpower who works on the production of assy air cleaner area, the use of the area, and electricity consumption. The large number of manpower affects the increasing of labor costs and the use of the area and electricity consumption affect an increase in factory overhead cost. Cost of raw materials being on the outside control of the company as the costs would come from supplier. The saving cost is calculated after improving and applying direct assy. The estimating of saving cost is Rp. 203,933,267.59 monthly. After implementing the direct assy, the work standardization is designed. The design of standardization work already performed the three types of standardizations. Those are standardized work chart (SWC), standardized work combination table (SWCT), and work instruction (WI).

Abstract

PT. X is one of company that concerns with continuous improvement.  PT. X attempts to apply the concept of lean manufacturing in order to identify waste. Value stream mapping is one of the tools from lean manufacturing that can illustrate the entire process and identify waste ranging from the arrival of raw materials to the delivery of finished goods. Value stream mapping will be carried out at PT. X for department A. Through the current state value stream mapping can be seen that there are some waste in PT. X for department A ranging from the arrival of raw materials to become finished goods, among others is waste motion, over-processing waste, defect waste, inventory waste, and waste waiting. Design of future state value stream mapping is based on the proposed improvement given to the company. Future state value stream mapping can reduce lead time 41% from the current state value stream mapping.
