Finishing Line Evaluation of Bracket product FWD RR Spring BT 1702 by Applying 8 Steps 7 Tools Method Toyota Production (Case Study: PT BA)

Abstract

PT Bakrie Autoparts is a company which runs in foundry and mainly produces cast iron such as wheel hub, brake drum, disc rotor and flywheel. The major problem encountered by this plant is the slow delivery to consumers because the finishing process takes too long time along with the increasing demand while there is no significant improvement. This research focuses on the mapping of the hindrances and problems in the finishing line of Bracket FWD RR Spring BT 1702, how much the actual output is, what causes the problem, and what improvement can be done to remove or reduce the hindrances. The method used is 8 Step 7 Tools Toyota Production System. Time measurement result and Output Standardd calculation is based on finishing line cycle time 142 seconds per pcs and output Standardd 25 pcs per hour. After applying the method of 8 Step 7 Tools Toyota Production System, cycle time line finishing can be reduced to 66 seconds and the output Standardd to 53 pcs per hour. The output line finishing improvement reaches 112% faster than the previous one. Besides that, the improvement makes a better perfomance Standardd in the finishing process of Bracket FWD RR Spring BT 1702 so the product is in better quality and it ensures the operators's work safety.
