Resumen
The Coral Triangle region is facing negative impacts due to unbalanced carrying capacity and inappropriate public behavior, leading to unsustainable reef tourism. As a result, there has been increased awareness and preference for sustainable reef conservation (SRC). This study evaluates the integrative perspective framework of tourists? heterogeneity preferences in SRC programs using a choice experiment conducted in Karimunjawa National Park (KNP), Indonesia. The study found that tourists preferred boat anchoring at the mooring buoy, a lower number of boats, smaller tourist groups with interpretation, added information boards, and environmental awareness education. Additionally, this research revealed that most tourists preferred the alternative SRC program and had a heterogeneous preference, which showed different features among each group. The scenario of an integrative program generated the highest value compared to the ?recreational management? and ?institutional control? scenarios. This evidence can assist policymakers in adapting policies for SRC programs and in potentially securing conservation funds associated with enhancing the institutional aspects of carrying capacity and marine environmental education for sustainable marine development.
