<![CDATA[Abstract: The Kapanca tradition is an important sequence in the customary marriage system of the Mbojo ethnic group and is still practiced by the community of Rontu Village, Raba District, Bima City. This article analyzes the implementation process of Kapanca and the social values embedded in it. The study employed a qualitative approach with an ethnographic case-study design. Data were collected through observation, interviews with traditional leaders, community leaders, families involved in the ceremony, and local residents, as well as documentation of customary activities. The data were analyzed through condensation, presentation, and conclusion drawing, while credibility was strengthened through source, technique, and time triangulation. The findings show that Kapanca is implemented through preparation, opening, core ritual, and closing stages. The ceremony does not merely mark the readiness of the bride-to-be to enter married life; it also functions as a space for reproducing social values. The main values identified include mutual cooperation, kinship, respect for customs and ancestors, religiosity, collective responsibility, and social solidarity. These values are reflected in family deliberation, role sharing, preparation of ritual equipment, application of henna, collective prayer, moral advice, and community participation in completing the event. The findings indicate that Kapanca functions as a mechanism for cultural preservation, social education, and the strengthening of social cohesion within the Mbojo community amid contemporary social change.
