The ongoing COVID-19 pandemic has brought several changes to people's lives worldwide. Responding to this global pandemic, socio-cultural transformation and adaptation are needed. The purpose of this study is to reveal the impact of the pandemic on the traditions of the Samin Tribe in Blimbing Village, Blora. Besides, the socio-cultural transformations and the role of opinion leader are also investigated. This qualitative study was conducted using two-step flow theory through in-depth interviews with Mbah Pramugi Prawironegoro, an elder for Samin Tribe of Blimbing Village, Blora. To define the concept of the Samin tribe and opinion leaders, a literature review was also conducted. The results of the study indicate that the social life of the Samin Tribe is not much affected by COVID-19, because they work as farmers. On the other hand, their traditions are adapted to the government policies by implementing health protocols. A Javanese analogy 'wong urip nek mudeng keiket' makes them obey the government and the opinion leader and believe will not be affected by the virus. Previous studies were limited to the concept of the Samin Tribe and their history, traditions, and beliefs. The contribution of this study is that the socio-cultural aspect of the Samin Tribe is analyzed concerning the COVID-19 impacts.
