Supra intensive shrimp cultivation has high economic potential and it has been developed in Kupa South Sulawesi. The existence of supra intensive shrimp pond cultivation technology not only has many benefits, waste water from shrimp ponds that are not managed properly can lead to degradation of ecosystems and decline of coastal biodiversity.Therefore, it is required the design of wastewater treatment plant (WWTP) to support the sustainable supra intensive technology. The purpose of this final task was to design WWTP that can be applied to supra intensive shrimp pond cultivation, and meets the quality standards of wastewater set by Ministry of Marine and Fisheries No. 28/2004 about General Guidelines for Shrimp Cultivation in Pond. Design process consists of determination of the capacity and characteristics of wastewater from supra intensive shrimp pond cultivation, and the determination of three alternative processing systems. Based on the consideration of several factors, such as processing load, technical aspect, economic and environmental aspects, one of the most suitable systems was selected. The WWTP is designed with the capacity 90 m3/day and consists of physical, chemical and biological processes using equalization, pre – sedimentation, coagulation, flocculation, sedimentation, anaerobic-aerobic biofilter, and sludge drying bed. The design process is done in two stages, namely stage one of a physical and chemical process and stage two of biological process. Based on the calculation of the dimensions of processing units, the required land area is 560 m2 and the budget cost is IDR.3,380,000,000
