Abstract

PT. AA adalah perusahaan yang bergerak dibidang industri kemasan plastik. Selama ini metoda penjadwalan produksi yang digunakan perusahaan adalah metoda First Come First Serve (FCFS) dan metoda ini tidak bisa mempercepat pemenuhan pesanan pembeli. Tujuan dari penulisan tesis ini adalah merancang penjadwalan produksi perusahaan yang dapat mempercepat pemenuhan pesanan pembeli dengan memperhatikan job susulan, pada mesin injection dan blow molding.
Metoda penjadwalan produksi yang diusulkan adalah metoda Longest Processing Time (LPT) yang dibalik jadi Shortest Processing Time (SPT). Penggunaan metoda ini akan membuat make span lebih kecil dibandingkan penggunaan metoda First Come First Serve (FCFS) yang digunakan perusahaan. Make span untuk mesin injection molding berkurang sebesar 27,039%, untuk mesin blow molding berkurang sebesar 25,886%, dan untuk seluruh mesin unit II berkurang sebesar 27,039%. Rata-rata utilisasi mesin naik sebesar 18,94%.

PT. AA is a plastic container company. The company uses FCFS method as the scheduling method of their production activities. By using this method, the company realizes that they can not meet the customers demand on time. The aim of this thesis is to design company's production scheduling that meet the customers demand, by paying attention to new coming jobs, at injection and blow molding machines.
The production scheduling method used in this thesis is reversing LPT order into SPT order. The result of this method is shorter make span than the method by FCFS.
Make span of injection molding is shorter 27.039% than FCFS value, blow molding is shorter 25.886% than FCFS value, and for the overall machine in unit II, the make span is shorter 27.039% than FCFS value. The average of machine utilization increase 18.94%.
