This study aims to analyze the role of the Mosque Administration Board or ‘takmirul masjid’ and its inhibiting factors in enhancing mosque vitality. This research is necessary as the commitment of the Mosque Administration Board to fostering mosque vitality needs to be reassessed. The most visible indicator is the non-participation of worshippers in both religious and social matters. Considering that the Muslim population is a majority and mosques, besides being places of worship, play a crucial role in shaping the character and cultural identity of Muslims, the role of the Mosque Administration Board is highly significant. This research employed a field study using a qualitative approach with a descriptive design. Data were obtained through field observations, interviews with research informants, and document analysis. Data collection techniques included observation, structured interviews, and documentation. Data analysis used inductive analysis techniques. The findings of this study indicate that the role of the Mosque Administration Board in enhancing mosque vitality is not optimal, as evidenced by the lack of involvement of worshippers in various obligatory and recommended prayers, as well as other religious activities. This situation arises due to several factors, including inadequate coordination and consolidation among the Mosque Administration Board, insufficient government support and attention, limited financial support, inadequate socialization and consolidation among worshippers, and the need for streamlining the number of personnel in the Mosque Administration Board.
