The Jatiluhur Reservoir is an important building in West Java Province whose dams the Citarum River. The location of the Jatiluhur Reservoir, which is the most downstream of the Saguling and Cirata Reservoirs, is where domestic, industrial, and agricultural wastewater pollution is accommodated from water catchment areas so that water quality decreases. This study aims to analyze the water quality in this reservoir at various depths. The study was conducted in September 2020 at 16 sampling points at a depth of 0-8 meters. The water quality parameters analyzed were Temperature, Dissolved Residue (TDS), pH, Dissolved Oxygen (DO), Fluoride (F-), Nitrate (NO3-N), Sulfate (SO42-), BOD5, COD, and Escherichia coli. Based on the study results, it was found that the concentrations of DO, BOD5 and COD at the monitoring location of the Jatiluhur Reservoir did not meet the quality standards. The concentrations of DO, BOD5 and COD respectively 1.00-3.99 mg/L; 3.10-17.00 mg/L; and 28.00-59.00 mg/L. These three parameters contribute to the decline in water quality. The status of water quality using the IP method is categorized as lightly polluted so that it affects the utilization of this reservoir, especially as raw water for drinking water. The highest level of contamination was at the floating net cages sampling location at a depth of 8 m. The decline in water quality in the Jatiluhur Reservoir is caused by organic substances originating from floating net cages waste.
This study aims to determine the profile of dissolved oxygen and H2S based on depth in the Jatiluhur Reservoir related to fish culture in floating net cages. The scope of this research is focused on the location of floating net cage cultivation. Dissolved oxygen distribution is classified as a positive heterograde type where dissolved oxygen levels higher in the metalimnion layer due to the photosynthesis process that occurs effectively by aquatic plants and phytoplankton. Jatiluhur Reservoir shows signs of organic pollution, with BOD5 and COD levels exceeding the quality standard. This organic substance comes from the waste of floating net cages. BOD5 and COD values that exceed the quality standard result in increased oxygen consumption during the decomposition process; therefore, a hypoxic layer occurs. This occurrence can cause water conditions to become anoxic, producing H2S gas. The H2S value in the Jatiluhur Reservoir was observed to exceed 0.002 mg/L and showed an increase in the metalimnion layer.
