Abstract
PT. Kecap Manalagi Dewata is a company that produces sweet and salty soy sauce. The raw material inventory quantity planning applied by the company has the risk of uncertainty in raw material requirements due to uncertain sales volume in every month. This uncertainty affects the determination of the optimal purchase quantity and inventory costs. The aim of this study is to determine the optimal purchase quantity of priority raw materials for soy sauce production based on minimum inventory costs.
The data collection techniques are interviews with companies and purposive sampling. This study compares the EOQ inventory control methods, Min-Max Stock, and Company Control (existing methods). The results showed that the priority raw materials for soy sauce production were sugar and tauco with 91.77% and 3.94% of fund absorption. The best prediction method is Quadratic Trend with the quantity needed for sugar and tauco in 2024 487,744 kg and 19,191 kg. The best inventory control method is the EOQ method with inventory cost savings of IDR 104,775.28 or 22.33% for sugar and IDR 104,647.47 or 22.30% for tauco.
Key word: Optimization of Purchase Quantity, Inventory Cost, Trend Projection, EOQ, Min-Max Stock.

Perencanaan kuantitas persediaan bahan baku yang diterapkan perusahaan memiliki risiko ketidakpastian kebutuhan bahan baku karena volume penjualan yang tidak menentu di setiap bulannya. Hal ini berpengaruh terhadap penentuan kuantitas pembelian optimal dan biaya persediaan. Penelitian ini bertujuan untuk menentukan kuantitas pembelian optimal bahan baku prioritas produksi kecap berdasarkan biaya persediaan minimum. Teknik pengumpulan data yang digunakan adalah wawancara kepada perusahaan dan purposive sampling. Penelitian ini membandingkan antara metode pengendalian persediaan EOQ, Min-Max Stock, dan Pengendalian Perusahaan (metode eksisting). Hasil penelitian menunjukan bahan baku prioritas produksi kecap adalah gula dan tauco dengan presentase penyerapan dana sebesar 91.77% dan 3.94%. Metode peramalan terbaik adalah Trend Quadratic dengan kuantitas kebutuhan gula dan tauco di tahun 2024 sebesar 487,744 kg dan 19,191 kg. Metode pengendalian persediaan terbaik untuk gula dan tauco adalah metode EOQ dengan penghematan biaya persediaan sebesar Rp 104,775.28 atau 22.33% untuk bahan baku gula dan Rp 104,647.47 atau 22.30% untuk bahan baku tauco.
