The study of interpersonal relationships is an aspect that cannot be separated from the discussion of social justice. The phenomenon is that social groups that are formed because of the affiliation of ethnic/racial similarities are very prone to conflict if group members are unable to adapt to all differences with other group members. This study aims to analyze the ethnic exploration and ethnic commitment in relation to the other group orientation of Javanese college students. The Multigroup Ethnic Identity Measure-Revised (MEIM) and Other Group Orientation inventories were distributed among 297 students and analyzed using a bias-corrected bootsrap method N = 5000 with a 95% confididential interval, indicating that other group orientations have a significant role as moderator (β = -0.03; p <0.05). These findings have implications for guidance and counseling services in universities, especially for developing attitudes towards other groups of students.
