Abstract
Tempe Lake is one of the largest lakes in South Sulawesi, with a 47.800 ha area and heavily utilized, leading to water quality degradation. This research aims to analyze water quality parameters using the NSF Water Quality Index. The research was conducted from June until August 2021. The sampling was done in three stations. Station I located in the middle of Tempe Lake- Station II, located close to the rice field area- and Station III, located close to the area of residence. The water quality analysis was done in the Laboratory of Water Quality, Faculty of Marine Science and Fisheries, Hasanuddin University, Makassar. There were 8 water quality parameters measured : temperature, turbidity, pH, TSS, DO, BOD, phosphate and nitrate. The results showed that all parameters, except phosphate, still met the Standard of PP No. 22/2021 of Water Quality Management and Pollution Control. Based on the NSF Water Quality Index, the Lake Tempe is categories as medium.
