Abstrak

PT. Bimuda Karya Teknik merupakan sebuah perusahaan manufaktur yang menerapkan sistem produksi
Make To Order (MTO) sehingga part yang diproduksi bervariasi tiap harinya. Aspek yang perlu
diperhatikan agar PT. Bimuda Karya Teknik mampu mengikuti kondisi tersebut adalah penjadwalan
produksi. Penjadwalan produksi yang dilakukan PT. Bimuda Karya Teknik belum menggunakan dasar
teori yang jelas sehingga output penjadwalan harian tidak sesuai dengan kondisi dilapangan.
Permasalahan lainnya adalah member departemen produksi sulit membaca penjadwalan yang diubuat
oleh departemen PPIC. Untuk mengatasi hal tersebut, metode penjadwalan produksi yang digunakan
untuk mengatasi penumpukan Work In Process (WIP) adalah job shop aktif. Selain itu dibutuhkan
format baru untuk penjadwalan produksi yang mudah dipahami oleh member produksi. Hasil penelitian
menunjukkan bahwa perbaikan makespan, waiting time, dan work in process (WIP) pada penjadwalan
tanggal 9 januari. Penjadwalan departemen PPIC menghasilkan makespan sebesar 10,2 jam, waiting
time 3 jam, dan WIP 2 part. Sedangkan metode job shop aktif menghasilkan WIP 8,3 jam, waiting time
3 jam dan WIP 1 part. Metode job shop aktif merupakan metode terpilih dan diterapkan pada
penjadwalan selanjutnya. Pada penjadwalan tanggal 11 januari didapatkan makespan sebesar 5 jam,
waiting time 1,8 jam, dan tidak didapati WIP dalam proses produksi..

Abstract

PT. Bimuda Karya Teknik is a manufacturing company that implements a Make To Order (MTO)
production system so that the parts produced vary every day. Aspects that need to be considered so that
PT. Bimuda Karya Teknik is able to follow these conditions, namely production scheduling. Production
scheduling carried out by PT. Bimuda Karya Teknik has not used a clear theoretical basis so that the
daily scheduling output is not in accordance with the conditions in the field. Another problem is that it
is difficult for members of the production department to read the schedules made by the PPIC
department. To overcome this, the production scheduling method used to overcome Work In Process
(WIP) is an active job shop. In addition, a new format is needed for production scheduling that is easily
understood by production members. The results of the study showed that the improvements in makespan,
waiting time, and work in process (WIP) were scheduled for January 9. PPIC department scheduling
results in a makespan 10.2 hours, a waiting time of 3 hours, and a WIP of 2 parts. While the active job
shop method produces a WIP of 8.3 hours, a waiting time of 3 hours and a WIP of 1 part. The active job
shop method is the method chosen and applied to the next scheduling. On January 11 scheduling, a
makepan of 5 hours was obtained, a waiting time of 1.8 hours, and no WIP was obtained in the
production process
