Abstract

Efficient inventory management is essential for facilitating seamless manufacturing at PT ZYX, especially in managing child part stocks from several vendors. Suboptimal inventory management may result in stock deficits or surpluses, affecting production continuity and operational expenses. This study seeks to evaluate kid part inventory according to its strategic significance and establish safety stock levels for category A goods. The ABC classification approach was utilized to categorize inventory according to significance, and safety stock analysis was performed to determine ideal stock levels for essential items. The findings reveal that among 35 child components, 8 things are classified as category A, 4 items as category B, and 23 items as category C. The maximum safety stock value was identified in child component ID 70025 at 2,891 pieces, whilst the minimum was recorded for ID 70002 at 248 pieces. These findings offer a systematic inventory management strategy that enables the organization to enhance stock control, reduce expenses, and increase operational efficiency. The adoption of ABC categorization and safety stock analysis is anticipated to improve inventory management, facilitating a more efficient supply chain and superior resource allocation.

Abstract

UMKM Tahu Sari Bumi Karawang is a tofu producer that produces 20,000 tofu beans per day. As a large producer, this MSME still applies manual cutting methods, which has an impact on limited productivity and product quality. The non-uniformity of tofu size not only affects the appearance of the product but also potentially reduces customer satisfaction. In addition, the limited use of tools makes the production process slower and reduces labor efficiency. Therefore, this study aims to design a tofu cutting tool to improve time efficiency and ensure more uniform cut results. The design of tofu cutting tools uses a value engineering approach, which is a structured and function-oriented team approach to analyze various functions in a product, system, or supply process. The goal is to increase value by identifying and eliminating unnecessary costs, while ensuring the achievement of desired performance with efficient cycle costs. Based on the research results, this tool consists of five main components with food grade stainless steel material. With an investment of Rp 1,466,000, this tool has a payback period of four weeks and can save cutting time up to 77%, and produce more uniform and precise tofu pieces. Keywords: Efficiency, Product Quality, Tofu Cutting Tool, Value Engineering
