Abstract

Nutrients (Nitrogen and Phosphorus) enter the waters in dissolved form or in sediment particles that reflect to condition of landuse activities that occur in the catchment area. This condition will determine the quality of the water and the lake productivity or trophic status. The purposes of this study were to assess how much nutrients input (N and P) that goes to Rawapening Lake and assess the biological response induced by lake. The observations was done by 4 times (2 times in the rainy season and 2 times in the dry season) in 9 of the river into the lake (River of Rengas, Panjang, Torong, Galeh, Parat, Legi, Muncul, Sraten, Kedungringin, Tuntang) as well as in 12 loc ations in the lake waters: area of Brebesan, Tourism of “Bukit Cinta”, Spring area, net cage 1, net cage 2, Kedungringin River estuary, and the outlet. The results showed that the TN input was up to 154,62 mg/sec and TP was up to 10,32 mg/sec. The Rawapening Lake had a deficit of TP up to 64.9% and TN up to 67.25%. It could be concluded that Rawapening lake had an acting as a sink and further it could served as a source of nutrients that lead to eutrophication condition.

Abstract

Cyanophyta (blue green algae) is one of the divisions of phytoplankton, microscopic aquatic organisms that some of them is harmful because secrete toxins and cause blooming so polluted waters. The purpose of this study was to determine the water quality in the Penjalin Reservoir in terms of physical and chemical parameters, determine abundance of Cyanophyta in Penjalin Reservoir, as well as determine the relationship between water quality with an abundance of Cyanophyta in order to control the blooming of Cyanophyta in Penjalin Reservoir. The method applied in this research is survey. The analytical method used to determine the water quality is descriptive method with table. Abundance of Cyanophyta were analyzed qualitatively and quantitatively. The relationship between physics and chemistry waters with an abundance of Cyanophyta were analyzed using correlation analysis. The results of the research in the waters of the Penjalin Reservoir obtained 25 species of Cyanophyta abundance ranged from 838.16 to 1322.77 ind.l-1, with the highest species abundance owned by Microcystis sp. Diversity index values ranged from 0.7 to 2.15 indicate that the diversity of Cyanophyta is classified, and the dominance index value of 0.009 to 0.29 indicates that no species dominates. Cyanophyta abundance in the waters of the Penjalin Reservoir 37,89% influenced by parameter TDS and Total P (r = 0,501) with equation Y = -701,5 + 33,4 (TDS) + 919,7 (Total P). Water quality in Penjalin Reservoir still within the range of good and decent for the life of organisms present in the reservoir.
