This communication later forms a formula, a pattern that is carried out by the community in responding to the various cultures that are carried out by each of them. The application of this multicultural concept can be taken as an example to the Hindu community in Sinduwati Village, Sidemen District, Karangasem Regency, which can impact multiculturalism in real life, in its concrete form, namely the existence of cultural communication between the Hindu community and the Muslim community in the village.
