Analisis Pengendalian Persediaan Bahan Baku Tepung Tapioka di CV Harum Mekar, Kabupaten Pati

Abstract

ABSTRACTRaw materials are the most important component in a production process. Therefore, good raw material inventory control will ensure smooth production and prevent shortages or excess inventory that can cause cost losses. This study aims to analyze tapioca flour raw material inventory control by comparing the Economic Order Quantity (EOQ) and Just In Time (JIT) methods with company policies at CV Harum Mekar, Pati Regency. The research method used is a case study with a quantitative approach using data on raw material requirements, ordering costs, and storage costs. The study was conducted in October-November 2025 at CV Harum Mekar. The location was chosen purposively considering that the company is engaged in a large-scale agroindustry. The sample was determined using a purposive sampling method, namely 1 employee each from the warehousing, purchasing, and production divisions. The research method used is a case study with a quantitative approach using raw material requirements data, ordering costs, and storage costs in 2025. The analysis was carried out through calculations of EOQ, safety stock, reorder point, maximum inventory, just in time and Total Inventory Cost (TIC). The results of the study indicate that the company's policy results in a total inventory cost of Rp2,327,642,302 per year. The EOQ method produces an optimal order quantity of 1,094,000 kg with a total inventory cost of Rp20,753,280 per year, while the JIT method produces a total cost of Rp418,975,614 per year. EOQ is the most cost-efficient method with an efficiency of 99.11%, while JIT is more realistic to implement because it considers the characteristics of perishable raw materials and smooth production.
