Mosques have an important role as places of worship and centers of religious and social activities for Muslims. However, many mosques still manage information manually, which often leads to access difficulties, lack of transparency and inefficiency. To overcome this problem, this research proposes the development of a web-based Mosque Management Information System (MISS) using the Agile method. Agile was chosen because of its flexible and structured approach, allowing for continuous feedback and adaptation to changing needs. The results of the development of the Mosque MIS include main features such as activity information, prayer schedules, Qibla direction, financial data, donation information and congregation data. This research shows that the use of a Mosque MIS can increase efficiency and transparency in mosque management. In conclusion, the Agile method has proven effective in developing Mosque MIS, producing a system that is adaptive and meets user expectations, as well as overcoming shortcomings in previous research by providing more complete features and better accessibility.
