Indonesia is a large multicultural country with 1340 ethnic groups (netralnews.com). To live in social harmony, we need to maintain cross cultural competence. With this reason, there is awareness that the inclusion of cross-cultural understanding (CCU) in multicultural education at university curricula to social and humanity sciences is crucial to language learners from different ethnic groups. This study aimed at exploring cross cultural competence (CCC) in the English as a foreign language (EFL) classroom at higher education in Indonesia. In this study, we explored CCC practices in the EFL classroom at English Department Universitas Negeri Makassar in 2018/2019 academic year. A questionnaire was distributed and responded by forty-four students. The data obtained from respondents were analyzed using descriptive statistics revealing the mean, standard deviation, skewness, kurtosis, and percentage of students' perceptions on the questionnaire dealing with CCC practices and CCU materials in multicultural education in EFL classroom in Indonesia. The results of the study revealed that the CCC under the CCU is a cornerstone to build social harmony and peace in multi-cultural society.
