<![CDATA[This study aims to identify the religious practices of fishing communities along the Asahan River in Tanjung Balai Selatan District, as well as the social and cultural challenges they face in maintaining harmony among diverse community groups. The research employed a qualitative phenomenological approach to understand the religious practices of the fishermen, with the location selected purposively due to the community’s strong religious traditions and the close relationship between religion, social values, and local customs. The study was conducted over three months, from May to July 2025, with informants including religious leaders, traditional leaders, fishermen, housewives, and youth, selected through purposive sampling until data saturation was achieved. Data were analyzed interactively through condensation, display, and conclusion drawing, and verified using triangulation of techniques and sources to ensure validity and consistency. The findings show that the fishing community along the Asahan River consistently maintains religious practices and local traditions, even though fishing activities occupy much of their time. Pre-departure prayers before going to sea and participation in socio-religious activities strengthen social solidarity and community cohesion. Differences in religion, customs, and daily habits require tolerance education and effective communication, as well as the role of community leaders and religious figures as mediators. The involvement of younger generations is key to sustaining traditions and communal values. Religious practices among fishermen are simple yet consistent, adapted to daily life: Muslim fishermen strive to observe the five daily prayers in congregation, pay zakat, fast, and celebrate Eid either at home or on boats, while Christian and Buddhist fishermen perform rituals according to their own beliefs. Pre-sea prayers serve as an important tradition for safety and livelihood. The community also participates in collective activities such as Quran recitations, Yasin, tahlilan, and sea charity. Interfaith social life remains harmonious due to mutual respect, cooperation, and teamwork at sea. Challenges arise from differences in religious practices, customs, daily habits, and youth’s lack of interest in traditional practices. Competition over fishing results and certain rituals, such as offering sesajen, may also cause social friction. Efforts to maintain harmony are carried out through deliberation, the role of community leaders, and collective awareness of the importance of mutual respect. In conclusion, the religious life of fishermen is not only individual but also reinforces social bonds and solidarity among community members despite cultural and generational challenges.]]>
