“…Normally, the Pearson's correlation coefficient between two variables, βi and βj, can be calculated as according to previous work [2]. Total phosphorus (TP) is the combination of various phosphorus species and is an important water quality parameter for investigating eutrophication of lakes and reservoirs [18]. Generally, TP is determined by combining the various forms of phosphorus converted to orthophosphate [19].…”

Lakes and reservoirs are an important sources of drinking water for human life. However, numerous water quality indexes show seasonal fluctuation under different climatic conditions. We conducted a one-year investigation of Taiping Lake in year 2022 to construct relationship between water quality parameters and water quality. High water temperature promotes the growth of algae, and the existence of N species could provide the essential nutrient substance for the growing of algae. Under the irradiation of sunlight, algae will consume carbon dioxide through photosynthesis and release oxygen which can raise oxygen levels in the water. However, the rapid growth of algae could influence the acid-base balance in water through the consumption of carbon dioxide; thus, resulting in the increasing of pH values. These pH changes may pose a threat to drinking water.

“…Tinggi rendahnya konsentrasi N dan P sangat tergantung pada aktivitas di sekitar perairan danau sebagai sumber masukan diantaranya adalah aktivitas pertanian, limbah organik dan limbah lainnya yang mengandung N dan P, kalium oksida (K2O) serta sirkulasi dan pertukaran massa air dari dasar perairan danau laguna ke permukaaan yang membawa berbagai muatan di dasar perairan yang bersifat toksik, sebagai ancaman terhadap biota yang di budidayakan, kejadian tersebut terjadi pada saat tahun 2015 silam yang mengakibatkan biota yang di budidayakan mengalami kematian massal. Produktivitas dan status trofik juga di pengaruhi oleh siklus hidrobiologi dan parameter lingkungan seperti suhu, cahaya, nutrient dan klorofil a yang berkorelasi positif terhadap status trofik (Kumar, Jindal et al 2023;Torres-Bejarano, García-Gallego et al 2023;Tometin, Chouti et al 2023).…”

Water quality and trophic status of waters play an important role in aquaculture activities because they will affect the growth process of cultivated fish, if the water quality and trophic status are low then they can support aquaculture activities in the waters of Laguna Lake, South Ternate City. The purpose of this study was to determine the water quality and trophic status in the waters of Laguna Lake in supporting and supporting freshwater aquaculture activities. The research method used in this research is descriptive qualitative, the results of air analysis are described based on Class and Water Quality Standards, while the trophic status is estimated based on Carlson, 1977. The results of the analysis show that the water quality in Laguna Lake is still in accordance with Class II Quality Standards. PP No. 22 of 2021, while the trophic level status in Laguna Lake is also classified in the oligotrophic category, namely TSI <40, TSI in Laguna Lake waters ranges from 20.69-23.28. Based on the results of the analysis of water quality and trophic status, it was found that the waters of Laguna Lake are still good and can support freshwater fish farming activities
