Penerapan Metode Pengendalian Bahan Penunjang Menggunakan Parameter Min-Max di PT XYZ.

Abstract

PT XYZ adalah perusahaan manufaktur komponen plastik yang menghadapi permasalahan belum adanya standar pengendalian persediaan bahan penunjang, khususnya stok minimum, stok maksimum, dan reorder point. Penelitian ini menerapkan metode Min-Max pada lima bahan penunjang yaitu, Bushing T2101 (+), Bushing T2101 (-), Bushing T171B (-), Bushing T171B (+), dan SEAL B6HF475M-00, menggunakan data pemakaian selama bulan Januari-Maret 2025. Parameter dihitung melalui safety stock, reorder point, stok minimum, dan stok maksimum berbasis rata-rata pemakaian, standar deviasi, lead time, dan quantity packing. Simulasi 30 hari menghasilkan stockout 0 dan fill rate 100%, menunjukkan bahwa metode Min-Max efektif sebagai acuan pengendalian persediaan untuk mengurangi risiko stockout dan overstock.

PT XYZ is a plastic component manufacturing company facing the absence of measurable inventory control standards for supporting materials, particularly in determining minimum stock, maximum stock, and reorder point. This study applies the Min-Max method to five supporting materials, Bushing T2101 (+), Bushing T2101 (-), Bushing T171B (-), Bushing T171B (+), and SEAL B6H-F475M-00, using usage data from January to March 2025. Parameters were calculated based on safety stock, reorder point, minimum stock, and maximum stock, derived from average daily usage, standard deviation, lead time, and packing quantity. A 30-day simulation resulted in zero stockout and 100% fill rate for all materials, demonstrating that Min-Max method is effective as an inventory control reference to reduce the risk of stockout and overstock.
