IMPLEMENTASI METODE QUALITY CONTROL CIRCLE UNTUK MENURUNKAN TINGKAT CACAT PADA PRODUK ALLOY WHEEL
ABSTRACT: In the industrial
competition, the service field also the manufacturing field has experienced rapid development. Each company compete to win the competition
to gain market share. The high level of product defects is a serious problem in
the Meshindo Alloy Wheel Corporation. It is caused by the complexity of the
types of defects that occur in the process. Therefore it is necessary for
continuous improvement effort to reduce the rate of defects that have occurred in the process.
This research has implemented the method of QCC (Quality Control Circle) with
eight steps to improve quality. The method of QCC used a tool called the seven
tools. We propose an improvement plan within a matrix plan improvements through
brainstorming process. Our research found that the biggest number of CTQ
(Critical To Quality) is the flaw
leaked. Then we do a search the root cause of the problem through a process of
brainstorming between QCC teams and the management of company. We found that the most dominant cause of the
defect is the low reliability of the machine,
the lack of rigor operator and low quality of material. In the Pareto
diagram , it appears that the largest percentage of leak defect, approximately
45.9 %. The improvement is only performed on the LT machine (machine of tester of leakage).
After repair of the LT machine, the percentage of defects leaking down from
1.86 % to 1.09 %. So there is a decrease of 0.77 % defect rate.
