Abstract

The practice of customary norms within Balinese Hindu migrant communities has experienced substantial transformation. Interaction between Balinese Hindu communities residing outside of Bali and local populations has led to cultural acculturation. This study aims to elucidate the social transformation embedded in the adaptation of customary norms as a response to the local cultural contexts of banjar adat. Using observation, interviews, and document analysis, this article found that customary norms are significantly influenced by the socio-geographical context outside of Bali. Social transformation appears in three distinct forms of simplification. First, in religious ceremonies, where practices are simplified to madya (medium) levels. Second, ritual practices have evolved, incorporating local elements such as woven bamboo offerings. Third, institutional transformation is evident in the collaboration between religious and traditional institutions to address community issues. Based on these findings, the study recommends integrating customary norms into local regulations to ensure a stronger legal framework and legitimacy. The findings are expected to contribute to the development of cultural policies and management of migrant communities, as well as enrich socio-cultural and anthropological studies on migration dynamics.
