Analisis Kandungan Nutrien (N, P) dan Pendugaan Status Kesuburan di Waduk Saguling, Jawa Barat

Abstract

Saguling Reservoir is man made lake that stem the flow of Citarum River. It has a major function as a hydropower and fisheries activities supporting floating cage. Nutrien input from Citarum River and KJA potentially increase the trophic state of Saguling Reservoir. Research was conducted from November 2012 until January 2013. Sampling was done in 3 stations of Saguling Resevoir (inlet, middle, and outlet). Water quality parameters include physics, chemistry, and biology was observed in this research. Nutrien concentration was analyzed from N:P ratio. Trophic state was estimated from TSI. Ratio of N: P showed a value of 24.2 which means P is the limiting factor in Saguling Reservoir. The value of TSI showed hypertrophic condition but characteristic of hypertrophic didn’t show during observed in Saguling Reservoir.
