Surau is a community-based non-formal Islamic educational institution that plays a significant role in shaping children's moral values in Minangkabau society, including in Korong Patamuan, Nagari Sikucur Barat, Kecamatan V Koto Kampung Dalam, Kabupaten Padang Pariaman. This community service article aims to describe the contribution of surau to the moral development of children in Korong Patamuan and to identify the forms of religious activities, the moral values instilled, the supporting factors, and the obstacles encountered during the process. This article is part of the output of a Community Service Program (KKN) carried out by students of [Nama Universitas]. A descriptive qualitative approach was used, with data collected through observation, interviews, documentation, and field notes involving children, Qur'an teachers, surau administrators, parents, and community leaders. The findings show that surau activities—such as reciting the Qur'an, memorizing short surahs, communal prayer, and religious gatherings after Maghrib—contribute to habituating worship, manners, discipline, and social care among children. Students supported these activities by assisting Qur'an teachers, accompanying children, and providing religious motivation, without replacing the central role of the surau and the community. Supporting factors included community support and children's enthusiasm, while obstacles included [kendala utama, mis. keterbatasan pengajar/waktu]. This article concludes that surau meaningfully contributes to children's moral formation through habituation, exemplary role models, and social interaction, and recommends continued collaboration between surau, families, and students for sustainable moral education.
