Minimasi Stockout Indirect Materials melalui Penerapan FSN EOQ dan JIT Purchasing di PT XYZ

Abstract

Indirect materials berperan penting dalam mendukung kelancaran operasional PT XYZ, khususnya pada kebutuhan ATK, RTK, dan APD. Namun, perusahaan masih mengalami stockout pada beberapa item Indirect materials yang menyebabkan terganggunya aktivitas operasional serta meningkatnya biaya pembelian darurat. Penelitian ini bertujuan menganalisis kondisi stockout, mengklasifikasikan material berdasarkan tingkat pergerakan, menyusun model pengendalian persediaan, serta membandingkan efisiensi biaya antara metode EOQ dan JIT Purchasing. Penelitian ini menggunakan pendekatan deskriptif-kuantitatif dengan metode studi kasus pada Departemen GA-HSE PT XYZ. Metode analisis yang digunakan meliputi FSN Analysis, EOQ, Safety stock, Reorder point, JIT Purchasing, dan Inventory Cost Analysis. Hasil penelitian menunjukkan bahwa metode EOQ mampu menurunkan biaya persediaan sebesar 69,84%, sedangkan metode JIT Purchasing mampu menurunkan biaya sebesar 71,09%, sehingga menjadi alternatif yang paling efisien. Namun, metode EOQ lebih sederhana dalam implementasi operasional. Dengan demikian, kedua metode dapat meningkatkan efektivitas pengendalian persediaan di PT XYZ.

Indirect materials play a significant role in supporting the operational continuity of PT XYZ, particularly in fulfilling the needs of office stationery, office housekeeping supplies, and personal protective equipment. However, the company still experiences stockout occurrences in several indirect material items, which disrupt operational activities and increase emergency purchasing costs. This study aims to analyze stockout conditions, classify materials based on their movement levels, develop an inventory control model, and compare the cost efficiency of the EOQ and JIT Purchasing methods. This research employed a descriptivequantitative approach with a case study design in the GA-HSE Department of PT XYZ. The analytical methods used in this study include FSN Analysis, EOQ, Safety stock, Reorder point, JIT Purchasing, and Inventory Cost Analysis. The results indicate that the EOQ method reduced inventory cost by 69.84%, while the JIT Purchasing method achieved a cost reduction of 71.09%, making it the most efficient alternative. Nevertheless, the EOQ method is considered simpler for operational implementation. Therefore, both methods can improve the effectiveness of inventory control at PT XYZ.
