Design and Implementation of Warehouse Stock Opname System Case Study : PLTGU Tanjung Uncang

Abstract

This study aims to design and implement a web-based stock opname system to enhance warehouse management efficiency at The Gas and Steam Power Plant (PLTGU) Tanjung Uncang. The system was developed to address limitations in manual inventory recording, which is prone to errors and lacks real-time data accessibility. The development process followed a structured approach using the Waterfall methodology, encompassing requirement analysis, system design, implementation, system integration and testing, and maintenance. The effectiveness of the system was evaluated using a descriptive quantitative approach through the User Acceptance Testing (UAT) method, involving ten users directly engaged in warehouse management activities. Four key aspects were assessed: system functionality, performance, user interface, and operational efficiency. The evaluation results indicate that all indicators scored above 80%, reflecting a high level of user acceptance and demonstrating the system’s effectiveness in supporting warehouse operations. This implementation represents a strategic move toward digital transformation in logistics within the energy sector and has potential for replication in other operational units.
