Enggano community is a plural society, besides ethnic variety, it is also multi-religion. They have five indigenous tribes (Kauno, Katora, Kaarubi, Kaharuba, and Kahaoa) and one migrant tribe (Kaamay). Kaamay is a new tribe created by the indigenous Enggano community to accommodate migrants to become part of the social structure of the Enggano community. The impact of the large number of migrants entering Enggano is the shift of the majority of believers from Christianity to Islam. Although very multiethnic and multireligion, Enggano is able to maintain harmony within and ensure the peace of its people. Very rare conflicts occur within the Enggano community. This is because adat has local wisdom in regulating community values and norms so that potential conflicts can be prevented. All Enggano people (including Kaamay) must obey the traditional rules because they are conditioned as part of the Enggano tribe and must give up their previous cultural identity. This paper shows that the domination of adat which is managed and adhered to together can prevent the occurrence of frictions within the community. Adat successfully guarantees the rights, obligations and social status of the members of community so that there is no social jealousy between migrants and indigenous people.
