The rapid development of information technology, particularly the internet, has significantly influenced access to information by making it faster and more accurate. In the education sector, information technology can be optimally utilized through websites as media for information dissemination and student registration to improve service quality. At Ummul Quro Islamic Boarding School, information delivery and new student admissions are still conducted manually, which limits efficiency and accessibility. Therefore, this research aims to develop an information system that functions as a medium for delivering information and managing new student registration so it can be accessed anytime and anywhere without requiring direct visits. The research employs the waterfall method, a systematic and sequential software development approach starting from planning to implementation. The results show that the developed web-based information system effectively improves information accessibility and service processes, particularly in new student admissions. The system enhances administrative efficiency, simplifies data input, reduces errors, accelerates data recording, and supports better management of Islamic boarding school information.
