<![CDATA[Indonesia, with its rich marine resources and more than 17,000 islands, has enormous tourism potential. The ecotourism sector, in particular, is spearheading inclusive economic growth and strengthening Indonesia's image as a leading global destination. Ecotourism is defined as responsible nature-based tourism activities focused on education, natural resource conservation, and, crucially, increasing local community incomes. This research focuses on the Karimunjawa Shark Sanctuary as a relevant case study. This shark sanctuary, a family initiative launched in 2019, seeks to transform the perception of sharks from mere objects of consumption to sustainable tourism assets, while preserving their habitat. By optimizing local resources and a construction concept predominantly using wood, the sanctuary offers an interactive educational experience with a variety of marine life.This shark sanctuary has significant potential to become a new economic powerhouse, creating opportunities for local fishermen to become educational guides, housewives to produce eco-friendly souvenirs, or young people to manage homestays, thus transforming into a catalyst for ecotourism development strategies that support community empowerment and well-being. This study aims to analyze the ecotourism development strategy of the Karimunjawa Shark Sanctuary to improve the local economy. The method used is a descriptive qualitative approach using the 4A concept (Attraction, Accessibility, Amenities, Ancillary services)]]>
