Zoning Design for the Protected Conservation Area of Pinang, Siumat and Simanaha Waters (PISISI) in Simeulue District, Aceh
Simeulue District has several conservation areas, including the Pinang, Siumat, Simanaha (PISISI) marine conservation area. To maximize the management of the marine protected area (MPA) of PISISI, which has been reserved by the Government of Aceh, it is necessary to analyze the management and zoning plan, especially in determining the location of the core zone (no-take zone). The core zone determination is the most important part in planning to protect coastal areas as a manifestation of sustainable management of fish resources and the environment. The research purpose is to determine the location of the no-take zone based on conservation targets that have high biodiversity value, analyze the optimum size of the no-take zone, and determine the zoning design in the MPA of PISISI, Simeulue District. Therefore, the Marxan model was used in this study, which is the most widely used MRA zoning design and planning tool. However, Marxan was unable to determine the priority location of conservation areas and the optimum size of the no-take zone. For this reason, a combination of Marxan and the MPA Size Optimization Tool was used. The study at the MPA of PISISI is an example of how the information generated by these two tools becomes a reference or a model that will be applied to other MRAs that have not yet compiled a zoning plan. The zoning results lead to a no-take zone proposal divided into eight sections with a size of 3 km which was obtained from the consideration of the home ranges of 55 high-economic fish species found in the MPA of PISISI. Based on the results of the analysis of the two instruments, the proposed core zone area is 5.14%, which meets the requirements of Marine and Fisheries Ministerial Regulation Number 30 Year 2010 stating that each marine conservation area must have a core zone with an area of at least 2% of the total area.
Keywords: marine conservation areas, Marxan model, MPA Size Optimization Tool, core zone, no-take zone.
