<![CDATA[The tradition of bathing with ornaments is one of the wedding customs of the Malay Muslim community in Talawi District, Batubara Regency, which is still maintained to this day. The continuity of this tradition indicates the interaction between Islamic values and local culture that shape the community's social practices. This study aims to analyze the forms of religious and cultural acculturation, symbolic meanings, and social functions contained in the bathing with ornaments tradition. The study used a qualitative method with a field study approach through observation, interviews, and documentation, supported by literature review. The research analysis uses acculturation theory to understand the process of acceptance, adaptation, and preservation of local cultural elements in the lives of Muslim communities without losing their religious identity. The results show that the bathing with ornaments tradition functions as a rite of passage that marks the change in social status of the prospective bride and groom towards married life. This tradition also contains symbols that represent the values of purity, responsibility, moral readiness, and hopes for the formation of a harmonious family. Although not part of the pillars or legal requirements of marriage in Islam, the community interprets this tradition as a means of strengthening religious values, preserving Malay cultural identity, and strengthening social solidarity. The research findings show that the relationship between religion and culture in the tradition of decorative bathing takes place through a harmonious acculturation process, so that local traditions remain sustainable without conflicting with the principles of Islamic teachings.
