Maksimasi Throughput Produk Garmen dengan Menggunakan Pendekatan Theory of Constraint (Studi Kasus: CV Suho Garmindo Bandung)

Abstract

Rapid development of manufactur industry makes all companies need to improve and enhance performance to achieve their goal in obtaining maximum throughput. CV Suho Garmindo, as a garment company, got problem in obtaining maximum throughput because of limited capacity. Therefor, CV Suho Garmindo applying the Theory of Constraint (TOC) to their evaluation and improvement. TOC method used in conducting improvement on CV. Suho Garmindo are constraint identification, constraint exploitation, subordination other sources, and constraint elevation. There are three kinds of products which are dresslim, koko, and veil, found constraint capacity on sewing workstation. Constraint is exploited by optimally utilizing sewing workstation using linear programming. The result of linear programming calculation, that with capacity might have, CV Suho Garmindo will obtain throughput maximum of Rp 17.999.840 if producing 265 pcs dresslim, 15,77 pcs koko, and 480 pcs hood. The results are reviewed by the exploitation of scheduling approaches to determine there is a new constraint or not. With the number of known production and by applying First Come First Serve (FCFS) scheduling method, CV Suho Garmindo faced new constraints i.e. scheduling system is not optimal and should be improved to such constraint. The scheduling method is converted into Campbell, Dudek, and Smith (CDS) method by applying batch process is not the same as batch transfers. The result shows makespan value, 28589.54 minutes, is bigger than 28080 minutes. The advice can be given are company needs to apply an overtime or adds number of machines in the constraint source with reached potential throughput 59.52% higher than the original throughput.
