In the last few days we have seen many actions of certain groups in society who want to undermine the harmony of Indonesian nation. Religious and racial issues are sensitive issues that can lead to disintegration. The solution to avoid disintegration is to strengthen unity. Strong unity comes in a long process. One process that can be conducted is through education. Education that can produce unity in Indonesia is an education characterized by the principle of multiculturalism. Multicultural education is actually education mandated by the National Education System. The law in Indonesia explains that all forms of education residing in the territory of Indonesia should pay attention to the value of multiculturalism. Multiculturalism is understood differently by diffferent countries. Multicultural education first emerged with the aim of calling attention to civil rights. The main purpose of the movement is to counter discriminatory practices against minority groups. Indonesia has a different history and culture certainly cannot directly apply the western version of multiculturalism. Multiculturalism must be understood as the foundation in building the life of nation and state. The development of character education based on multiculturalism in Indonesia must be in line with the principles formulated by national education ministry and in accordance with heterogeneous Indonesian society.
