This study aims to determine the trophic status of the Jatigede Reservoir based on the Trophic State Index. The study was done from August 2020 to March 2021. This study used a survey method. Determination of the research location is done by the purposive sampling method. Sampling was carried out at six stations representing three reservoir zoning. The parameters analyzed were the physical and chemical parameters of the waters, namely water transparency, temperature, pH, dissolved oxygen (DO), total phosphorus, nitrate and chlorophyll-a. The trophic status was measured by the Trophic State Index method. The average value of the trophic state index in the Jatigede Reservoir ranges from 57.82-60.35, so that it is classified as eutrophic waters. The trophic status during the study was influenced by several physical and chemical parameters measured at each observation station.Pages: 249-254 | 39 Views 8 DownloadsDownload Full Article:
