Social capital is considered an important element in the social life of the community. Social capital that leads to social harmony plays a role in maintaining social stability between individuals. Social capital is also needed in an effort to deal with all kinds of things, especially when a natural disaster occurs. This study aims to find out and explore the values of harmony in the management of the earthquake emergency response that occurred in Malang in 2021. This study used a qualitative research method with a case study approach. The subjects in the study were 15 people who were selected through a purposive sampling method with criteria as community leaders, religious leaders, volunteers, and residents, both affected and unaffected. The results of the study show that social capital in the form of social harmony plays an important role where these social values are used as a basis in forming an emergency response system which includes initial handling, distribution of aid, and post-earthquake rebuilding (reconstruction). The implications of social capital have a positive and negative impact on the affected residents. These positive impacts are in the form of equitable distribution of aid, the rapid progress of development, and an increased sense of harmony and solidarity with the residents. While the negative impact is the emergence of disputes among residents related to assistance caused by misunderstandings among residents.
