Abstract

Abstract. CV. X is a company that produces and sells robe and koko shirt. This company has problems in fulfilling customer orders and often experiences backorder problems. To solve this problem, use Theory Of Constraints. The stages used are identifying constraints, exploiting constraints, subordination of non-contraints, and constraints elevation. The results of the identification of constraints, it is  thread scissors work stations and the entire process Quality Control (QC) work station, experienced capacity constraints or bottlenecks. At the constraints exploitation stage, a linear program calculation is carried out to determine the optimal amount of production for the robe and koko shirt. The results are the optimal number of robes according to the number of requests, while the optimal number of koko shirts is less than the number of requests.  In the subordination non constraints is carried out by applying the Drum Buffer Rope method, which gives a time buffer, namely 3 hours of overtime at the thread scissors work station and 2 hours at the entire process QC work station. The suggestion of increasing working hours may not be successful if it is carried out in the long term, so it is continued at the  constraints elevation by providing additional workforce of 3 operators at the thread scissors work station and 1 operator at the entire process QC work station. Proposals for improvements made at the subordination non constraints and constraints elevation stages are checked with linear program calculations and the result is that after repairs are made, customer demand can be fulfilled.

Abstrak. CV. X adalah perusahaan yang memproduksi dan menjual produk gamis dan baju koko. Perusahaan ini memiliki permasalahan dalam memenuhi pesanan pelanggan dan sering mengalami masalah backorder. Untuk mengatasi permasalahan ini, menggunakan Theory Of Constraints. Tahapan yang digunakan adalah mengidentifikasi constraints, mengeksploitasi constraints, subordinasi non-constraints, dan elevasi constraints. Hasil identifikasi constraints diperoleh stasiun kerja gunting benang dan stasiun kerja Quality Control (QC) keseluruhan proses, mengalami kendala kapasitas atau bottleneck. Pada tahapan eksploitasi constraints dilakukan perhitungan programa linier untuk mengetahui jumlah optimal produksi produk gamis dan baju koko. Hasilnya jumlah optimal gamis sesuai dengan jumlah permintaan, sedangkan jumlah optimal baju koko kurang dari jumlah permintaan. Pada tahapan subordinasi non constraint dilakukan dengan menerapkan metode Drum Buffer Rope, yaitu memberi time buffer berupa overtime sebanyak 3 jam pada stasiun kerja gunting benang dan 2 jam pada stasiun kerja QC keseluruhan proses. Usulan penambahan jam kerja ada kemungkinan tidak berhasil jika dilakukan dalam jangka panjang, sehingga dilanjutkan pada tahapan elevasi constraints dengan memberikan tambahan tenaga kerja sebanyak 3 operator pada stasiun kerja gunting benang dan 1 operator pada stasiun kerja QC keseluruhan proses. Usulan perbaikan yang dilakukan pada tahap subordinasi non constraints dan elevasi constraints diperiksa dengan perhitungan programa linier dan menghasilkan bahwa setelah dilakukan perbaikan, permintaan pelanggan dapat terpenuhi.
