The Second APEC Workshop of SAKE 14-1 Integration of Satellite Application and Computational Tool for Marine Conservation Area Planning E. Elvan Ampou, Frida Sidik and Candhika Yusuf Institute for Marine Research and Observation Bali, Indonesia ABSTRACT The design of a marine conservation area or so called Kawasan Konservasi Laut (KKL) should meet the goals of KKL itself. The objectives for each type of marine conservation area are varies and almost exclusively focused on habitat protection which leads to the conservation of biological diversities and sustainable fisheries. Satellite application has been widely used to support marine designs. This paper describes how we incorporate data on the spatial distribution of key coastal habitats (such as mangrove and coral reef) and water quality with coastal hydrodynamic model for the design of marine conservation area. The study employs field observation, satellite data processing and modeling. Using a computational tool called MARXAN, we combine those biological and physical information as the primary drivers for the selection of sites for marine reserves. The site location is in Pemuteran, Buleleng, Bali. Keywords: Kawasan Konservasi Laut (KKL), Biological diversity, MARXAN. Figure 1. Design Map of MPA in Pemuteran (North Bali) using MARXAN Biodiversity is defined, and the importance of and threats to marine biological diversity are assessed. A review of current scientific knowledge with respect to marine biological diversities are presented, along with commentary on the particular threats to diversity in the various types of marine ecosystem. This is followed by a general discussion of the ways in which government and the public can protect marine biological diversity to support Marine Conservation Area Planning with integrated to satellite application and computational tool.
