This paper discusses the implementation of the Islamic religious learning approach model in Jembrana-Bali, a case study at State Senior High School (SMAN) 1 Negara. The focus of this paper is to explore the effectiveness of the multicultural learning model used in learning Islamic religious education. This multicultural learning model is a means of creating harmonious interactions and integrating understanding of diversity between Hindu and Muslim students, thus leading to peaceful practices in the educational environment. Sources of data were obtained through unstructured observations and interviews from July to September 2019. This paper shows that the learning process of Islamic religious education with a multicultural approach turns out to be able to shape the character of students, both Hindu and Muslim to become humanist, tolerant, and inclusive. In shaping character and to develop understanding of diversity, the learning approaches used are the contribution approach, additive approach, and decision-making and social action approaches proposed by Allison Cumming-McCann. Thus the interaction of students at SMAN 1 Negara, both Hindu and Muslim, leads to the process of acculturation and enculturation of two different religions and traditions.
