| Summary: | Channelization of the river cause to the formation of oxbow lake that make the physical
and chemical conditions to change and affect to aquatic living organism that are plankton.
The objectives of the research were to know plankton community structures and water
quality in Oxbow Lake of Bengawan Solo and to determine the relationship between
density of plankton with water quality in oxbow lake. The research has been done from
March to April 2013 in Oxbow Lake of Bengawan Solo River Desa Sidowarno Kabupaten
Klaten and the research has been done for 5 weeks. Samples were taken once a week from
five observation stations. Samples of Plankton were taken using plankton nets by filtering
50 l of water with plankton net and samples of plankton were preserved with 4% formalin.
Observation of the plankton has been studied in Laboratorium Ekologi Perairan UGM by
entering sample of plankton into Sedgwick Rafter Counting Cell (SR) and the sample of
plankton were observed by microscope 10x10. Water quality parameters that are
brightness, water temperature, dissolved oxygen, free carbondioxide and alkalinity were
measured directly while TSS (Total Suspended Solid), pH, organic matter, phosphate and
nitrate were measured in the laboratory. Plankton which have been found in Oxbow Lake
Bengawan Solo were 40 genus which consist of 22 genus of phytoplankton and 18 genus
of zooplankton. Phytoplankton which dominate in oxbow lake are Synedra while
zooplankton which dominate in oxbow lake are Cyclops. The average value of the
abundance of plankton in the five observation stations ranged between 60-125 cells/l and
plankton diversity index ranged between 1,27-1,74. Water transparency in Oxbow Lake of
Bengawan Solo ranged between 34,55-94,99 cm |
