ANALISIS PRODUKSI PADA MESIN SPEED DENGAN PENDEKATAN TAGUCHI UNTUK MENGURANGI CACAT PRODUK DI PT INDUSTRI SANDANG NUSANTARA
Abstrak: PT Industri
Sandang Nusantara (PT
ISN) is a
yarn spinning company
located at Secang,
Magelang. The company currently
produces the kind
of yarn use
raw material polyester.
Polyester are sent
by PT ISN center.
PT ISN using a
variety of machines in the production process, one that is machine
Speed / Roving machine. Problems encountered in
machine Speed is yarn unevenness (CV%). Methodology used in this is identify
factor control and factor noised; and what impact on output. Second, choosing
orthogonal arrays (OA) is appropriate. Third, after identifying and influence,
the next step is to conduct experiments. Forth, the data processed using ANOVA
test and S/N Ratio. Fifth, confirmation of the results of research use Loss
Function.
From the analysis of the data collected on the PT ISN, the obtained
results : total failure occurring is 7%
of the total production,
with the contribution
of failure unevenness
is 42.30%. Taguchi
method is used
to determine design the
best configuration parameters
of machine. The
design of machine
configurations obtained from this
study shown to
reduce losses due
to defects obtained
deviation decrease in
yarn unevenness (CV%) of 67.30%. Based on the facts in the field any
defect in the engine speed will return to the beginning of the blowing machine
and could cost Rp 15.000/product disability. As for the total loss function before
the application is Rp 15.300 and after
the application of the method Rp 5.300, so the company could save Rp 10.000.
