One of the important aspects of the environment is sanitation. Sanitation is human effort to create a safe and comfortable environment. Processing of liquid waste through a floating septic tank is a form of environmental sanitation. The purpose of this study was to determine the effectiveness of floating septic tanks in Kodingareng Island, Makassar City, in terms of parameters of BOD, TSS, pH, temperature and MPN Coli.This research is experimental. This research begins by reviewing related literature, environmental survey, preliminary study, making a model of floating system waste management and checking the results of the effluent. This floating septic tank is expected to be the right sanitation facility to be used by people on the coast and islands. After 45 days of septic tank installation and 3 effluent sampling with a span of 2 days at the same effluent point, the research shows several results. Measurement of BOD and TSS and MPN Coli levels in the effluent of waste treatment, with a septic tank, showed results above the quality standard of the Minister of Environment and Forestry Regulation No. 68 of 2016 concerning domestic waste requirements. The decrease in BOD levels from the first test sample to the third test sample was 40.9% (580 mg / l, 483.24 mg / l, 342.3 mg / l). At TSS levels, the decrease from the first to second test samples was 22.7% (180 mg / l, 139 mg / l, 207 mg / l), while the temperature and pH were still in accordance with the quality standard. For MPN Coli parameter is still far above the quality standard. The result of parameter test is an extrapolation or estimation model. This method can show the estimation model of the residence time of wastewater in the treatment system so as to achieve the estimated time of effluent according to quality standards.
