Abstract

This study aims to develop a Lean Warehousing-based warehouse management system to improve operational efficiency and logistics effectiveness at XYZ Educational Institution. The research was motivated by several key issues identified in the Stationery Warehouse, such as an inefficient layout, unsystematic item arrangement, and a manual, non-integrated stock recording process. These conditions resulted in various forms of waste-particularly in time, labor, and costs-which ultimately caused delays in item distribution and a high rate of stock recording errors. A qualitative descriptive approach was employed, with data collected through literature review, field observations, surveys, and interviews with warehouse staff and service users. Class-Based Storage used as method in warehouse layout. Lean Warehousing principles were used to identify sources of inefficiency and to design improvements through physical layout optimization and the development of a digital stock recording system. The proposed system was designed to streamline distribution processes, minimize data entry errors, and improve the transparency and accuracy of logistics information. The results indicate significant improvements in warehouse performance: item distribution time was reduced by 46%, stock recording errors decreased by 30-35%, and motion waste was reduced by 28% due to layout optimization. Additionally, 87% of respondents reported that the new system was more efficient and user-friendly compared to the previous one. This study also proposes a Lean Warehousing implementation model that can be adopted by other Educational Institution units as a practical solution to warehouse and logistics management challenges.
