Manual donation management at Pondok Pesantren Daarul Multazam poses challenges related to efficiency, reach, and transparency, which could potentially reduce donor trust. This study aims to design and develop an integrated web-based donation reception information system to address these issues. The software development methodology used is the Prototype Method, which emphasizes an iterative process through continuous evaluation with stakeholders to ensure the system built meets the real needs of users. This system is developed using a combination of modern technologies, namely the Laravel framework for the backend, Vue.js for a dynamic user interface, and Tailwind CSS for responsive design. The result of this study is a functional web donation application that has undergone a series of tests. Functional testing using the Black Box Testing method showed that all features worked as expected, while feasibility testing through User Acceptance Testing (UAT) showed a task completion success rate of 100%, indicating that the system is highly acceptable and easy to use. The limitation of this study is its focus on a single case study, and future research could explore the scalability as well as the implementation of advanced security features. The key features of the system include campaign management, online donation processes through payment gateway integration, and a crucial module, the Fund Usage Report, to enhance transparency and accountability, providing a replicable model for similar nonprofit institutions.
