Disaster mitigation efforts through increased vigilance and preparedness must be sustained. The Disaster Preparedness Group (KSB) is a partner of the BPBD of Rembang City in disaster risk reduction. People who are members of KSB in areas prone to abrasion disasters are still pretty much clueless about abrasion disaster mitigation efforts. Public ignorance of disasters can result in losses that will befall residents. KSB has a vital role in providing information and assistance for the surrounding community. The research objectives were 1) to determine the incidence of abrasion in Kragan Village, 2) to analyze the role of KSB in handling and adapting the community to abrasion disasters. A qualitative approach is used in this research. The research focused on the activities and roles of KSB in handling coastal abrasion. Research informants include family heads who live in abrasion-prone areas, village heads, and community leaders. The results showed that the KSB, during a disaster and pre-disaster, had a role in providing socialization and education to the community. However, this activity still encountered obstacles, so that it was not yet effective. The obstacles include the absence of operational funds for activities owned by the Disaster Preparedness Group, no supporting facilities and infrastructure for activities, the existence of conditions where some members do not care, and the condition of the people in the area. The role of the community in self-supporting coastal management in reclamation has various challenges, particularly in the aspects of funding, mindset, infrastructure, and community participation, that need solutions.
