The Miftahul Jannah Taklim Assembly, a non-formal da'wah institution, conducts religious development activities that emphasize both enhancing religious understanding and strengthening family life among its congregation. This study investigates the da'wah management practices of the Miftahul Jannah Taklim Assembly in promoting family harmony in Batang Terap Village, Perbaungan District. A qualitative research method with a descriptive approach was employed. Data collection involved observation, interviews, and documentation, with research informants comprising the head of the taklim assembly and congregation members. Findings indicate that da'wah management at the Miftahul Jannah Taklim Assembly is operationalized through the functions of planning, organizing, implementing, and evaluating. Planning involves preparing schedules for religious studies and selecting materials relevant to the congregation's needs. Organization is achieved through the allocation of responsibilities among administrators. Da'wah activities are carried out via regular religious studies and social programs. Evaluation is conducted by monitoring attendance, participation, and observable changes in congregational attitudes.
