Kegiatan operasional perusahaan perkebunan kelapa sawit sangat bergantung pada ketersediaan pupuk yang memadai dan tepat waktu. Namun, manajemen persediaan pupuk sering menghadapi tantangan seperti fluktuasi permintaan, keterlambatan pasokan, serta potensi kelebihan stok yang dapat menyebabkan pemborosan biaya penyimpanan. Penelitian ini dilakukan di FAP Agri Tbk. PT. Bhumi Simanggaris Indah, Kabupaten Nunukan, Kalimantan Utara, yang hingga saat ini belum menerapkan metode pengendalian persediaan berbasis perhitungan kuantitatif seperti Economic Order Quantity (EOQ). Tujuan dari penelitian ini adalah untuk menganalisis sistem manajemen persediaan pupuk serta mengevaluasi efektivitas pengendalian persediaan menggunakan pendekatan metode EOQ. Metode yang digunakan meliputi pendekatan deskriptif dan analisis kuantitatif EOQ dengan data primer dan sekunder, yang diperoleh melalui observasi langsung, wawancara, kuesioner, dan dokumentasi. Hasil penelitian menunjukkan bahwa persediaan pupuk selama tahun 2024 tergolong aman dan mencukupi untuk mendukung operasional kebun. Namun, terdapat ketidakefisienan, seperti overstock pada jenis pupuk tertentu (misalnya NPK dan CuSO₄), yang menyebabkan biaya penyimpanan tinggi serta pemanfaatan stok yang rendah. Perhitungan EOQ menghasilkan jumlah pemesanan optimum yang lebih efisien dibanding sistem aktual perusahaan, disertai dengan estimasi frekuensi pemesanan, safety stock, dan reorder point yang dapat dijadikan acuan dalam pengelolaan stok. Dari hasil tersebut, disimpulkan bahwa penerapan metode EOQ secara berkala dapat membantu perusahaan dalam mengendalikan persediaan secara lebih efisien, menekan biaya penyimpanan, dan mengurangi risiko terjadinya overstock maupun kekurangan stok (stock-out). Oleh karena itu, disarankan agar perusahaan mempertimbangkan penggunaan EOQ sebagai bagian dari sistem manajemen persediaan pupuk secara menyeluruh.

The operational activities of palm oil plantation companies heavily rely on the adequate and timely availability of fertilizers However, fertilizer inventory management often faces challenges such as demand fluctuations, supply delays, and the potential for excess stock which can lead to wasteful storage costs. This research was conducted at FAP Agri Tbk PT Bhumi Simanggaris Indah, Nunukan Regency, North Kalimantan, which until now has not implemented the Inventory control methods based on quantitative calculations such as Economic Order Quantity (EOQ) The aim of this research was to analyse the fertilizer inventory management system and evaluate the effectiveness of inventory control using the EOQ method approach. The methods used include descriptive approaches and quantitative analysis of EDQ with primary and secondary data, obtained through direct observation, interviews, questionnaires, and documentation The results of the study indicated that the fertilizer inventory during the year 2024 is considered safe and sufficient to support the operational needs of the farm However, there are inefficiencies, such as overstocking of certain types of fertilizers (eg, NPK and CuSO4), which cause to high storage costs and low utilization of stock. The EOQ calculation yields an optimal ordering amount that is more efficient compared to the company's actual system, accompanied by estimates of ordering frequency, safety stock, and reorder points that can serve as a reference in stock management From these results, it can be concluded that the periodic application of FOQ methods can assist the company in managing inventory more efficiently, reduce storage costs, and minimize the risk of overstocking and stock outs Therefore it is recommended that companies need to consider the use of FOQ as part of a comprehensive fertilizer inventory management system Keywords: Inventory Management, Fertilizers, Economic Order Quantity (EOQ), Inventory Control PT Bhumi Simanggaris Indah
