PENINGKATAN KAPASITAS PRODUKSI MELALUI PENERAPAN THEORY OF CONSTRAINT, PENJADWALAN MESIN PARALEL DAN BOTTLENECK SCHEDULING PADA PERUSAHAAN SHEET METAL WORK
ABSTRACT: This study aims
to increase the
production capacity of the
server rack 08U Type
Double A-Series Wallmounted
BRI on company
X. Current production
did not reached
the expected target
of 117 units / week because of the bottleneck workstation. The study
began by identifying the bottleneck workstation
using the Theory
of Constraints (TOC).
The result of
identification process showed two
bottleneck work stations, that are work station Punching and Ovencoating. The
production capacity was improved by performing the steps as follows: 1) Add 1
machine at punching station, 2) perform job scheduling on parallel machines at
punching station using Short Processing Time (SPT) criteria; 3) perform
job sequencing on
bending station using
Weighted Shortest Processing
Time (WSPT) criteria; 4 ) adds
overtime at ovencoating stations, and 5) implementing bottleneck scheduling
method to sequence all
jobs. The Results
of this study
showed that makespan
was reduced by 12.03% and production capacity increased by 41.9% so
that the production target of 117% can be achieved.
