PENYUSUNAN BUKU PENGAYAAN KELAS X BERBASIS PENELITIAN IDENTIFIKASI MAKRO INVERTEBRATE SEBAGAI BIOINDIKATOR KUALITAS AIR SUNGAI CATUR MADIUN

Abstract

This study aims to determine the diversity of macroinvertebrate species and the quality of the CaturMadiun River by using macroinvertebrates as bioindicators. Researchers used a qualitative descriptive study. The method used in this study was macroinvertebratebioindicators, the technique used in taking samples was purposive random sampling technique, sampling was carried out at three stations, namely the upstream middle part and the downstream part, sampling was carried out every 2 weeks for one month. The data analysis used was the Family Biotic Index (FBI) which was supported by physical and chemical parameters. Based on the research exploratory variety of macroinvertebrates in the Catur River, 7 orders from 8 macroinvertebrate families were found. At station I, it was found that FBI = 4, 76 with a good category, polluted with some organic matter, FBI station II = 6.44 with a bad category, very much polluted, and FBI station II = 6.50 with a bad category, very much polluted. The assessment of the feasibility of the enrichment book from the material expert validator was obtained with a percentage of 72, 91% with the criteria "Enough", and from the media expert validator obtained a percentage of 65% with the criteria "Enough".
