Currently, this process is manually conducted through handwritten notes on paper, which are then photographed and shared with technical personnel via WhatsApp. This process is time-consuming and prone to errors. This study proposes the development of a web-based Transformer Load Information System using the Waterfall method and UML modeling approach. The Waterfall method is employed to outline the workflow of the system development, encompassing stages of analysis, design, implementation, testing, and maintenance. UML modeling is used to design the system by illustrating the structure and interactions among its components. The outcome of this study is a web-based system that enables field employees to input transformer load data efficiently. Technical staff can readily access this data and generate reports, enhancing the efficiency and accuracy of transformer load management. The system is tested using the black box testing method, which aids in identifying errors and shortcomings in the application. This testing process ensures the system functions as intended and meets user requirements. This research contributes a web-based information system that enhances the efficiency and accuracy of transformer load data collection. The amalgamation of the Waterfall method and UML in system development provides clear and structured guidance, resulting in a well-planned solution. This system can serve as a reference for developing similar solutions. }, issn = {2548-3412}, pages = {62--72}, doi = {10.51211/itbi.v9i1.2549}, url = {https://87383.shichuantrade-tw.tech/index.php/ITBI/article/view/2549} }
