Indonesia is a country known for religious harmony, differences in ethnicity, race, mindset and character of each person as well as differences in beliefs, make it vulnerable to conflict in the community, such as religious conflicts that occur between Muslims and Buddhists in Bentek West Lombok, religious marriage conflicts in North Lombok, conflicts of land destruction of Ahmadiyah congregations in East Lombok. Social conflicts will turn into religious conflicts and even political conflicts can potentially become religious conflicts if there is a lack of dialogs and cooperation in the midst of society, therefore interfaith dialog is very necessary. The research method used in this research is a qualitative method with a descriptive analysis approach. The results of this study indicate that, the way to avoid conflict is to return to clinging to the truth of each religion and holy book and make traditions and culture as a medium to glue relationships in society, one form of culture in society that can be a medium for interfaith dialog is the tradition of Takbiran and Maulid Prophet Muhammad. Takbiran culture and Maulid culture can be a place to strengthen the brotherhood of religious people, residents who are far away become close, can make residents who are close as brothers because in fact hostility does not exist, there are only brothers who have different opinions. Culture can be a dialog to strengthen brotherhood between religions in Indonesia.
