People from different ethnicities, tribes, clans and religions inhabit a harmonisation village. The research problem is why the people of Sibadoar village have obedience to preserve the harmonisation village and whether there is a threat to maintaining Sibadoar village as a harmonisation village. To obtain the data used, descriptive qualitative research methods with data collection techniques, in-depth interviews, direct observation, Focus Group Discussion (FGD) and literature study. Research informants consisted of the Sipirok sub-district head, the Sibadoar village head, the LMD head, village officials, and non-village apparatus groups, namely, community leaders, religious leaders, traditional leaders and youth and community leaders who knew the object being asked. Based on research, the community's obedience to preserve the Harmonized Village's status is mainly due to the fabric of a sense of kinship in the Dalihan Na Tolu bond. With this concept, they feel like one unit, so whatever their brother's shortcomings must be forgiven because it will be an embarrassment for the villagers. Dalihan Na Tolu custom strongly influences the community in daily activities, including traditional, both in the form of siriaon (joy) and siluluton (sadness).However, the development of technology, transportation and information has slowly influenced the community's determination to maintain the status of a harmonisation village, especially among teenagers
