Analysis of Inventory Management in UD. Bintang Antik Sejahtera Tulungagung
Keywords:
Inventory Management, Traditional Models, Just-in-Time (JIT), Theory of Constraints (TOC), Marble Craft IndustryAbstract
This research analyzes the inventory management practices at UD. Bintang Antik Sejahtera, a marble crafts industry located in Tulungagung, Indonesia, with a focus on enhancing operational efficiency. The study critically evaluates the application and effectiveness of Traditional models (Economic Order Quantity - EOQ, Reorder Point - ROP), Just-in-Time (JIT) principles, and the Theory of Constraints (TOC). A qualitative descriptive methodology was utilized, involving extensive data collection through in-depth interviews, direct observations, and comprehensive document and literature reviews. The data underwent thematic analysis to uncover key patterns and strategies, with a supplementary quantitative analysis using EOQ and ROP formulas. The study reveals that the company employs a hybrid inventory management model, where EOQ and ROP aid in determining optimal order quantities and timing. JIT principles are applied through a make-to-order production system and the maintenance of minimal inventory levels. Simultaneously, TOC assists in pinpointing critical constraints such as material supply issues and production bottlenecks. The integration of these three distinct approaches has demonstrably led to improvements in operational efficiency, enhanced cost control, and increased adaptability to dynamic environmental challenges. This research concludes that a combined inventory management strategy, balancing traditional models with JIT and TOC, provides significant strategic advantages for small, craft-based enterprises, fostering greater operational resilience and supporting sustainable inventory practices, particularly in resource-constrained settings.
