Water Quality Status of Jatigede Reservoir Sumedang Regency, West Java

Abstract

With the captured fisheries sector as a livelihood for residents around Jatigede, it is feared that water quality will decline. Another function of the Jatigede Reservoir is to irrigate irrigation canals, control floods, source PLTA power, and raw water to serve the people of Sumedang, Indramayu, and Cirebon city. The intended purpose is to determine the quality of water in the Jatigede Reservoir. This research was carried out in Jatigede Reservoir from November 2020 to August 2021, using the survey method. The method of determining the location used a purposive sampling method, carried out at five stations representing Jatigede Reservoir. The water quality parameters used are temperature, pH, dissolved oxygen, and brightness. The results of observations of water quality in Jatigede Reservoir with temperatures ranging from 28°C-29°C, pH ranging from 6.67–8.35, dissolved oxygen ranging from 6.8–7.83 mg/l and brightness ranging from 70-93.8 cm indicate that the water quality of the Jatigede Reservoir is still categorized into good water quality and is ideal for capture fisheries sector activities in the Jatigede Reservoir. The results of the status of water quality in the waters of the Jatigede Reservoir are included in the category of Fulfill Quality Standards to Lightly Polluted, and the average Pollution Index value ranges from 1.75 to 3.01 in class II water quality standards and 0.86-1.94 in class III water quality standards. Water quality in Jatigede Reservoir during the research was influenced by the input of river flow in the form of organic and inorganic waste. Water pollution control strategies can be carried out by increasing the inventory and identification of pollutant sources, improving waste management, determining the capacity of the pollution load, increasing knowledge and community participation in waste management, increasing supervision of wastewater development, and improving water quality monitoring.
