USULAN PENERAPAN METODE SIX SIGMA UNTUK MENGURANGI TINGKAT KECACATAN PADA PROSES PRODUKSI PIPA API 14 INCH DI PT BAKRIE PIPE INDUSTRIES
ABSTRACT: PT. Bakrie
Pipe Industries is a company
engaged in the
production of steel
pipe. Pipe - steel pipe produced by PT. Bakrie Pipe
Industries is used for a variety of needs such as: pipes for oil and
gas , for
the installation of
water pipes, pipes
for construction purposes,
and for other purposes. PT.
Bakrie Pipe Industries always
maintain the quality of the resulting production
and efforts to minimize the failure existing production of the
company's. Therefore, Do research using the six
sigma method with
methodology DMAIC (Define,
Measure, Analyze, Improve,
and Contorol) expected by using
this method can minimize the defects and also improve the speed of production.In
the define stage, the selection of products to research the specs API steel
pipe with 14-inch size that
has defects percentage
of 5.25% and
therefore this product
the focus of research.Furthermore the Measure stage is
measurement sigma level company, the results of these measurements show the
value of 26,285 DPMO with sigma level was 3.44 sigma that indicates that value
still far from the target of 6 sigma.The next stage is a Analayze stage to analyze the causes of production failure
that occurred in production, using Ishikawa diagram and FMEA tables.Then the
Improve stage is giving suggestions for improvement and suggestions given for
companay with: the application
of methods of
DOE (Design Of
Experiments) with factorial
21 to find
the optimal distance in
screw machine, giving
proposed a tool
is Roll Waterpass
and application form monitoring for
the surveillance for
removing the beads process. After
do some implementations gained increasing value
21,662 DPMO and sigma value of 3.52 sigma.
