This study aims to examine the communication model implemented by the Nurul Iman Youth Mosque in shaping the character of its members. The research employed a descriptive qualitative approach with data collected through interviews, observations, and documentation. Data analysis was conducted using the Miles and Huberman interactive model, which includes data reduction, data presentation, and drawing conclusions, grounded in Harold D. Laswell’s communication theory. The results of the study are as follows: First, the mosque’s chairman and members act as communicators, delivering messages related to Islamic morals, discipline, responsibility, and solidarity. Second, the messages focus on strengthening moral values, social care, cooperation, and religious principles through meetings, religious studies, and social activities. Third, the media used include face-to-face meetings, internal meetings, WhatsApp Groups, Instagram, Facebook, and mosque announcements. Fourth, the primary target of the development program is internal members, although activities also involve surrounding youth. Fifth, the effects observed include the development of disciplined, socially conscious, and morally upright youths who are capable of becoming agents of change in their communities.This study aims to examine the communication model implemented by the Nurul Iman Youth Mosque in shaping the character of its members.
