Abstract :
Quality control is a management activity to measure quality characteristics
and existing products, compare them with specifications or requirements, and
take appropriate action if there is a difference between the actual appearance
and standardization, as well as for PT. Sinar Semesta. A strategy that can
guarantee quality is a strategy that is able to maintain process stability, so that
it can be controlled for the purpose of minimizing defective products. In this
study, the problem with Eq Spacing products was backgrounded. Where there
are still many defective products found. The purpose of this study is to
determine the quality control of Eq Spacing at PT. Sinar Semesta, and
proposals that can be taken to overcome these problems with the Six Sigma
method. This research uses the Six Sigma method which includes five stages of
analysis, namely Define, Measure, Analyze, Improve, and Control. With quality
control can be known. There are three types to There were three types of
defects studied in January - June 2022, namely Cracks, namely the number of
defects 199 with a percentage of defects of 28.84%, Flow Faults, namely the
number of defects of 178 with a percentage of defects of 25.80%, Rat tails,
namely the number of defects of 313 with a percentage of defects of 45 .36%
with a cumulative percentage of 100.00%.
