Abstract

ABSTRAK PT XYZ adalah perusahaan pewarna tekstil yang berlokasi di Cikarang, Jawa Barat. Dimana dalam proses produksinya, salah satu bahan baku utamanya adalah soda ash. Selama tahun 2021 perusahaan mengalami kelebihan persediaan bahan baku sebesar 17.197,15 kg. Adanya persediaan stok bahan baku yang banyak maka dapat berakibat pada tingginya ongkos simpan. Dari permasalahan diatas maka dilakukan analisis manajemen persediaan soda ash PT XYZ menggunakan metode continuous review system. Tujuan dari penelitian ini adalah untuk mengetahui metode manajemen persediaan yang memberikan total biaya persediaan paling minimum dengan variabel lot pemesanan, cadangan pengamanan dan titik pemesanan kembali. Hasil penelitian menunjukan metode continuous review Q-back order menghasilkan total biaya yang paling minimum sebesar Rp 1.055.187.808,4 dengan jumlah lot pemesanan optimal sebesar 10.301 kg, safety stock sebesar 565 kg dan melakukan reorder point ketika bahan baku tersisa 2.622 kg. Kata Kunci : continuous review system,  persediaan, probabilistik. ABSTRACT PT XYZ is a textile dyeing company located in Cikarang, West Java. Wherein the production process, one of the mainly raw materials is soda ash. In 2021 the company experienced an excess of raw material inventory of 17,197.15 kg. The existences large stock of raw materials can result in high storage costs. From the problems above,  an analysis of PT XYZ's soda ash inventory management was conducted using the continuous review system method. the research aim to determine the inventory management method that provides the minimum total inventory cost with ordering lot variables, security reserves, and reorder points. The results show that the continuous review Q-back order method produces the minimum total cost of Rp. 1,055,187,808.4 with the optimal number of ordering lots of 10,301 kg, safety stock of 565 Kg, and reorder point when the remaining raw materials are 2,622 kg. Keywords: continuous review system, inventory, probabilistic.

Abstract

Basically, all companies both big and small are always connected to the distribution of goods. The XYZ company is UMKM, the factory that is located at Ujung Berung, Bandung. The Company has three tofu factories that will distribute tofu into four different markets. This factory does not have a tofu flow distribution which results in high postage costs. In this study, the tofu flow distribution will be determined so that the cost of distributing tofu can be minimized. The method that can be used to determine the cost of distribution of tofu is the transportation method. The transportation methods used to solve the problems in this research are North West Corner (NWC), Least Cost and Vogel's Approximation Method (VAM) to determine the initial solution. Then optimized using the Stepping Stones method to get the minimum distribution costs. The calculation results obtained will be compared with the costs used by the previous company, with the hope that the results of this study can be considered by the company to be used in the tofu distribution
