Makrozoobentos Sebagai Indikator Biologis dalam Menentukan Kualitas Air Sungai Suhuyon Sulawesi Utara
Abstract
Makrozoobentos dapat digunakan sebagai parameter biologis dalam menentukan kualitas sungai karena hidupnya relatif diam di dasar sungai. Penelitian ini bertujuan untuk menentukan kualitas air Sungai Suhuyon Sulawesi Utara berdasarkan indeks keanekaragaman makrozoobentos. Penelitian dilakukan pada musim panas yaitu bulan Mei sampai Juni 2015. Lokasi penelitian ditentukan dari bagian hulu, tengah dan hilir sungai dengan 3 ulangan di setiap lokasi. Kualitas air Sungai Suhuyon ditentukan berdasarkan indeks keanekaragaman makrozoobentos Shannon Wiener (H’) menurut kriteria Wilhm (1975). Makrozoobentos di Sungai Suhuyon terdiri dari 3 Filum, 4 Kelas, 10 Bangsa, 21 Suku dan 22 Marga. Kualitas air Sungai Suhuyon Sulawesi Utara berdasarkan indeks keanekaragaman termasuk dalam kategori tercemar sedang (H’=2,45).
Macrozoobenthos can be used as a biological parameter in determining water quality of the river because they relatively stick on the riverbed. This study aims to determine water quality of Suhuyon river in North Sulawesi based on macrozoobenthos biodiversity index. The study was conducted during dry season, from May to June 2015. Three locations chosen for this study were the upstream, midstream and downstream part of the river, with 3 replications in each location. The quality of Suhuyon river was determined by Shannon Wiener biodiversity index (H’) of macrozoobenthos using classification of Wilhm (1975). Macrozoobenthos in Suhuyon river consisted of 3 Phylum, 4 Classes, 10 Orders, 21 Families and 22 Genus. Based on biodiversity index, water quality of Suhuyon River is categorized into moderately polluted (H’=2.45).
