Global climate change has emerged as a significant threat to coastal regions, with one of its most visible consequences being severe shoreline abrasion. In Karawang Regency, West Java, this issue has become increasingly alarming as the coastline continues to retreat by several meters, placing large areas of land at risk and disrupting the lives of coastal communities. This study aims to implement and assess an integrated approach to coastal environmental management, focusing on the use of discarded tire waste in combination with mangrove revegetation as a method to reduce abrasion. The research applies a mixed-method approach that combines quantitative data, such as measurements of shoreline abrasion, sediment accumulation, and tidal flooding, with qualitative insights gathered through interviews and direct field observations. This methodological design allows for a comprehensive analysis of both the physical impacts of the intervention and the social outcomes related to community involvement and empowerment. The use of used tires as materials for wave breakers, wave dampers, and sediment traps has proven to be more effective and cost-efficient than traditional coastal defense structures. These tire-based installations have not only reduced wave energy and minimized erosion but have also encouraged sedimentation in previously eroded areas. As a result, coastal progradation has occurred in several locations, with the shoreline advancing by several meters. This has led to a measurable expansion of the buffer zone protecting nearby settlements, improving the long-term resilience of these communities. When combined with mangrove restoration efforts, the tire-based structures contributed to a sustainable bioengineering solution that supports both ecological and social objectives. The integration of technology and natural vegetation helped stabilize the coastal environment, restore degraded ecosystems, and promote biodiversity. In addition, the initiative became a model for community engagement, encouraging local participation in environmental conservation. This innovation has been formally recognized through the issuance of a national patent in Indonesia, highlighting its potential as a replicable solution for other vulnerable coastal areas. © 2025, Hysen MANKOLLI.
