Abstract
An increase in consumer demand that causes raw material stocks to run out or excess stock of raw materials in warehouses will cause losses because consumers can lose or increase inventory costs. Pabrik Tahu XYZ orders raw materials when there are only 2-5 bags of soybeans left. Pabrik Tahu XYZ has also experienced a shortage of raw material stock twice during the 2021 holidays. For this reason, this study proposes the use of a raw material inventory control method to control the total cost of raw material inventory at the Pabrik Tahu XYZ. To find out the estimated amount of raw material usage in the 23 - 44 period (August 2022 - February 2023), a forecasting technique is carried out. Furthermore, this study will propose raw material control using the lot sizing method, namely the Economic Order Quantity (EOQ) and Period Order Quantity (POQ). The best forecasting results for the use of soybean raw materials is the Cyclic method with an MSE value of 287065.311. The optimal total cost of raw material inventory using the EOQ lot sizing method is IDR 1,722,906.00. Keywords: Forecasting, Inventory, Inventory Control, Lot Sizing

| Additional Information: | Terjadinya kenaikan permintaan konsumen yang menyebabkan kehabisan stok bahan baku atau stok bahan baku di gudang berlebih, maka akan menyebabkan kerugian karena dapat kehilangan konsumen atau bertambahnya biaya inventory. Pabrik Tahu XYZ melakukan pemesanan bahan baku ketika persediaan kacang kedelai hanya tersisa 2-5 karung. Pabrik tahu ini juga pernah mengalami dua kali kekurangan stok bahan baku pada saat hari raya tahun 2021. Untuk itu, penelitian ini mengusulkan penggunaan metode pengendalian persediaan bahan baku untuk mengendalikan total biaya persediaan bahan baku di Pabrik Tahu XYZ. Untuk mengetahui perkiraan jumlah pemakaian bahan baku di periode 23 – 44 (bulan Agustus 2022 - Februari 2023), maka dilakukan teknik peramalan. Selanjutnya, penelitian ini akan melakukan usulan pengendalian bahan baku dengan menggunakan metode lot sizing yaitu Economic Order Quantity (EOQ) dan Period Order Quantity (POQ). Hasil peramalan terbaik pemakaian bahan baku kacang kedelai adalah dengan metode Siklik dengan nilai MSE 287065,311. Total biaya persediaan bahan baku optimal menggunakan metode lot sizing EOQ sebesar Rp 1.722.906,00. Kata Kunci: Inventory, Lot Sizing, Pengendalian Persediaan, Peramalan | |||||||||
