ABSTRACT
Indonesia has a diversity of tribes, languages, religions, and belief systems. This diversity, on the one hand, has a great potential for the development of the Indonesian nation; on the other hand, there is also a sectarian danger where each person wants to prioritize the interests of their own group, resulting in conflicts between ethnic groups. If such conflicts are ignored, it will threaten the unity of the Indonesian nation. Therefore a strategy is required that will unite all ethnic groups, languages, religions, and belief systems. One of the cultures shared by all ethnic groups in Indonesia is gotong royong. Gotong royong, or mutual cooperation, can unite the entire Indonesia toward a just and prosperous nation. This paper wants to confirm the indicators of gotong royong and the sample of behavior that may explain the concept of gotong royong. Using confirmatory factor analysis, we found that gotong royong can be explained with the help of three indicators, namely: helping each other, making decisions together, and respecting the neighborhood. Furthermore, from the item difficulty analysis, the easiest item to answer as a sample of gotong royong is to respect the neighborhood. However, the most difficult item to answer comes from making decisions together.
