Abstract
Kertas test liner merupakan salah satu produk dari PT.
Buana Megah yang kualitasnya ditentukan oleh beberapa
karakteristik kualitas yang kritis. Jenis cacat yang paling banyak
terjadi adalah kertas gembos sebesar 47% dari seluruh jumlah
cacat. Kertas gembos terjadi pada proses slitting rewinding. Pada
keseluruhan proses slitting rewinding, kertas gembos ditentukan
oleh kinerja dari mesin rewinder.
Suatu penelitian dilakukan untuk menentukan pengaturan
parameter-parameter proses yang tepat pada mesin rewinder agar
dapat meminimalkan cacat kertas gembos. Parameter-parameter
proses tersebut adalah tension kertas, tekanan rider roll dan
kecepatan rewinder. Rancangan eksperimen menggunakan
matriks ortogonal L9. Metode Taguchi digunakan sebagai metode
optimasi untuk meminimalkan cacat kertas gembos.
Dari hasil penelitian didapatkan pengaturan parameter
proses yang tepat pada rewinder untuk produk test liner yaitu
tekanan rider roll sebesar 940 kg, kecepatan unwinder sebesar
650 mpm dan tension kertas sebesar 2,5 lbs/in. Namun demikian,
penerapan parameter-parameter proses yang baru, tidak dapat
menurunkan prosentase cacat gulungan kertas yang gembos pada
kertas test liner.

Test liner paper is one of few products from PT. Buana
Megah which quality is determined by some critical
characteristics. The biggest contributor of defects is deflated
paper roll which contribute 47% from total defects. Deflated
paper roll mostly occur in slitting rewinding process especially in
rewinder machine.
An experiment is conducted to determine the suitable
process parameters' setting for rewinder machine so that the
deflated paper roll defect can be minimized. Those process
parameters are paper tension, rider roll pressure and rewinder
speed. Experimental design that being used is orthogonal array
L9. Taguchi method is used as the optimization method to reduce
deflated paper roll defect.
The result shows that the suitable process parameters'
setting for test liner is rider roll pressure at 940 kg, unwinder
speed at 650 mpm and paper tension at 2,5 lbs/in. The application
of the new process parameters can not lower the deflated paper
roll defect in test liner paper
