Facility and infrastructure management at SDIT Brilliant School Bukittinggi is still carried out manually, so the processes of recording, monitoring, and reporting inventory are not yet running optimally. This situation has led to several challenges, such as difficulties in retrieving data, delays in report generation, and the ineffectiveness of the school’s facility oversight process. Therefore, a digital system is needed to assist in managing facilities and infrastructure more effectively and systematically. This study aims to determine the state of facility management prior to the implementation of a digital system, identify issues arising in the facility management process, design a digital-based facility registration system using the BRIL-SMART application, improve data accuracy and transparency, and streamline the processes of inventory management, tracking, and real-time reporting of facilities. The research type employed is Research and Development (R&D) using the ADDIE development model, which consists of the analysis, design, development, implementation, and evaluation stages. The BRIL-SMART application was developed using the Laravel framework, Metronic style, CSS, and a MySQL database. This system features several key functions, including login, dashboard, add item, item loan, inventory monitoring, inventory report, and item damage report. The research results show that the BRIL-SMART application was successfully developed and is capable of helping to make the management of school facilities and infrastructure more effective, faster, and more organized. Based on the functional suitability test results, the application received a score of 100% in the “very good” category. The usability test yielded a score of 87% in the “very acceptable” category, while the compatibility test yielded a score of 100% in the “very acceptable” category. Additionally, the content validity test yielded a score of 0.93 and the linguistic validity test a score of 0.83, both categorized as valid. Based on these research results, the BRIL-SMART application is deemed suitable for use as a facilities and infrastructure management system at SDIT Brilliant School Bukittinggi because it enhances the effectiveness of real-time school facility inventory, monitoring, and reporting processes.
