<![CDATA[Digital transformation in sports administration management is a crucial need to improve the effectiveness, efficiency, and accuracy of match data management. In the implementation of POPDA Banten, especially the badminton sport branch, the administrative process still faces problems in the form of unintegrated data management, potential data duplication, input errors, and delays in the validation process. This study aims to develop and evaluate the usability of the POPDA Banten 2026 Badminton Sport Branch Management Dashboard based on ReactJS in a multi-role user environment. The study uses a Research and Development (R&D) approach with a Prototyping development model consisting of the stages of needs analysis, prototype design, prototype evaluation, system implementation, and testing. The dashboard was developed using ReactJS on the frontend side, Golang with Gin Framework as the backend, RESTful API as the data communication mechanism, and MySQL as the database. Usability evaluation was conducted using the System Usability Scale (SUS) method involving 27 respondents consisting of Superadmin, Admin, and Field Staff users according to system access rights. The implementation results show that the dashboard is able to support the process of participant administration, data validation, match management, and information presentation in an integrated manner through a multi-role user mechanism. The usability test results obtained a SUS score of 70.65, which is included in the Acceptable category with a good level of user acceptance. These results indicate that the dashboard has an adequate level of ease of use and is suitable for use as a supporting system for managing the administration of the POPDA Banten badminton sports branch. This research contributes through the development of a web-based sports information system that integrates ReactJS technology, role-based access rights management, and SUS-based usability evaluation as an approach to producing more effective and easy-to-use digital sports administration services]]>
