Environmental Conditions Support Ecosystem Services in Jatigede Reservoir, Indonesia

Reservoir has many benefits such as providing a source of drinking water and a source of food from capture fisheries which can be categorized as ecosystem services. This paper aims to see how the environmental conditions of Jatigede Reservoir waters produce provisioning services. The environmental conditions analyzed in this study are physical, chemical, and biological, as well as water quality status using the Storet method. This can affect the results of ecosystem services which show that the results of capture fisheries in rainy season there are 8 types of fish. In the dry season, the condition of Jatigede Reservoir, as seen from the designation of drinking water sources, was heavily polluted, which showed that the benefits as a source of drinking water were less suitable for consumption. Jatigede Reservoir water quality status in class 2 fisheries designation is heavily polluted and class 3 is moderately polluted. Judging from the phytoplankton index (0.589‒1.395) and zooplankton index (1.161‒2.093), the water conditions in the dry season were heavily polluted to unpolluted, this can be seen from the many types of fish caught, such as 17 species. The environmental condition of the Jatigede Reservoir waters is very influential in supporting ecosystem services.
