Quality is an important aspect that has to be prioritized by company because quality
is the standard expectations of the product that offer by the company and agreed by
customer to satisfy the customer’s expectation. However, to this day many company
still facing the similar issue where the quantity of the nonconformity product is
higher than targeted standard. PT. KMI, a manufacturing company that produce
ceramic products is one of the company that face the issue, the highest defect is
coming from casting department in the production of 2P product has more than 10%
from the total output. Most of the 2P products are having issue in the appearance
which cannot satisfy the customer’s requirement. The aspects that affected by the
high amount of defect are quality, delivery and output, cost, and rework. This
research will focus on implementing DMAIC to reduce the number of the defects
and maintain the number of defect is lower than the standard, conducting root
causes analysis with fishbone diagram to identify the potential causes and
implementing corrective and preventive action to control to reach the zero defect.
From the analysis there are 27 corrective and preventive action identified and able
to be implemented, the result is reducing 10% of the appearance defect from the
production process.
