This study aims to analyze the role of teachers as agents of traditional Islamic culture at the Nurul Wujud Albarokah Foundation, East Pontianak. This research was carried out at the Nurul Wujud Albarokah Foundation, located on Jalan Panglima Aim, East Pontianak District, Pontianak City, West Kalimantan Province, using a qualitative approach and a single case study design that refers to the Standards for Reporting Qualitative Research (SRQR). Data were obtained through moderate participatory observation, semi-structured in-depth interviews, and documentation studies of six purposively selected informants. Data analysis uses the interactive model of Miles, Huberman, and Saldaña, which includes data condensation, data presentation, and conclusion drawing and verification. The validity of the data is ensured through triangulation of sources and methods. The results of the study show that teachers carry out three main roles as cultural agents, namely transmitting Islamic values through the integration of classical books with local wisdom, preserving the five main religious traditions in the form of book reading, maulid, tahlilan, taklim assembly, and local prayers, and becoming social mediators based on Islamic values in people's lives. The research also identified three adaptation strategies implemented by teachers, namely digitizing da'wah media, reframing traditional narratives to be relevant to the younger generation, and strengthening collaboration with students' families. These findings reinforce the urgency of the policy of empowering teachers as cultural agents based on Islamic traditions. The originality of the research lies in the integration of Geertz's theory of cultural agents, Cavalli-Sforza and Feldman's oblique transmission, as well as the concept of ta'dīb Al-Attas to explain the role of ngaji teachers in non-formal Islamic education in West Kalimantan.
