Analisis Kualitas Perairan Sungai Subayang Berdasarkan Indeks Biotilik sebagai Pengayaan Modul Mata Kuliah Ekologi Perairan

The study was conducted to determine the quality of the waters of theSubayang as enrichment Aquatic Ecology module in November 2015 - January 2016.Stages of the research is the analysis of water quality based on the Biotilic indexSubayang River, the next stage of enrichment courses Aquatic Ecology modules usingADDIE models. The research found 25 familia divided into 8 orders in which the threeorders of groups EPT is the order Ephemeroptera (4 familia), Plecoptera (2 familia),Trichoptera (6 familia), and 5 orders of the non-EPT is the order Odonata (4 familia),Coleoptera (3 familia), Hemiptera (3 familia), Diptera (4 familia), and Neotaeniglossa(1 familia).

EPT abundance ranged from 25% -100%, which is highest abundance in stationV and the lowest at the station VI. Index sensitivity level is highest at V station with thelowest index value at station 4 and the third with an index value of 3.21. Based Biotilicindex, the quality of river waters Subayang ranged from uncontaminated until beingpolluted. The results of the research can be used as enrichment Aquatic Ecologymodule
