ANALISIS KUALITAS PERAIRAN SUNGAI RAMAN DESA PUJODADI TRIMURJO SEBAGAI SUMBER BELAJAR BIOLOGI SMA PADA MATERI EKOSISTEM
Abstract: River is one of fresh water ecosystem which
is very important in human life since it is the most practical and economical
source in fulfilling domestic and industrial needs. Therefore, it should meet
the quality standards. The research
objectives were: 1) knowing the quality
of waterway in Raman River, Pujodadi, Trimurjo, based on the physical, chemical
and biological aspects; 2) turning the information intoa Biology learning
source on Ecosystem subject. The data were directly observed in the river by
measuring the physical factors (temperature, stream, turbidity); chemical
factors (pH, DO); and biological factor (macro invertebrates). The results
were: temperature 24-29oC ; stream 0.3 – 0.6 mm/s; turbidity 33.5-3.7 NTU; pH 4.1-5.2;
and DO 2.07-2.35 ml/I. Furthermore, micro vertebrates found were; a) Plecoptra;
b) Tricoptra; c) Mollusca, d) Ephemeroptra; and e) Hemiptra. In each station,
they were classified as insects and non-insects. The insects found were: 1)
Odonata; 2) Tricoptra; 3) Ephemeroptra; 4) Plecoptra. Based on those
parameters, the waterway quality was qualified as light wasted. The results can
be turned into student worksheet as a Biology learning source, especially on
Ecosystem subject.
