This study explores the indigenous knowledge of the Madurese tribe in conserving marine and coastal ecosystems on Gili Ketapang Island, Indonesia. Amid global environmental challenges like overexploitation and climate change, community-driven conservation that integrates indigenous knowledge with modern strategies is crucial. This research uses an ethnographic approach to examine the tribe's cultural and ecological practices, particularly their conservation methods. Data were collected through participant observation, interviews with key informants, and documentation, then analyzed with a developmental research sequence methodology. Findings reveal that Petik Laut , a sea offering ritual, symbolizes the harmonious relationship between humans and nature, viewing the sea as a living entity deserving respect. Practices include using eco-friendly fishing gear ( onjem ), observing Fridays as a no-fishing day for marine regeneration, and protecting sacred coastal sites. Sustainable adaptations, such as free-range goat farming, further support ecosystem preservation. These culturally rooted practices underscore the relevance of indigenous knowledge in addressing modern environmental issues. By blending indigenous knowledge with ecological principles, the Madurese tribe demonstrates how local communities can significantly contribute to global marine and coastal conservation efforts, emphasizing the importance of preserving cultural heritage and ecological integrity. © 2026 Department of Sociology, National University of Singapore.
