Based on the research results, it can be concluded that the activities of the Majelis Ta'lim Kanzul Ulum cover three main areas: education, da'wah, and social service. In the field of education, the Majelis regularly holds daily religious studies, monthly religious studies, and special religious studies on Islamic holidays. In the field of da'wah, it coordinates Rebana training and manages Rebana groups, organizes Salawat Dibaiyah meetings, organizes infaq collections for those who wish to contribute, and facilitates Qurban savings programs. Meanwhile, in the social field, the Majelis plays an active role by organizing assistance for orphans and the poor, providing ta'jil, breaking the fast, and sahur during the month of Ramadan, and holding collective celebrations such as Eid al-Adha. These activities show that the Majelis Ta'lim Kanzul Ulum functions not only as a place to learn religion but also as a center for social solidarity and community empowerment.
