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).

Abstract

Persawahan merupakan habitat yang baik bagi kehidupan amphibi. Amphibi memiliki fungsi ekologis sebagai penyeimbang ekosistem dan sebagai bioindikator lingkungan. Penilitian ini bertujuan untuk menganalisis keanekaragaman amphibi di areal persawahan Boleuvard Kota Tondano berdasarkan nilai indeks Shannon-Wiener. Penelitian ini menggunakan metode Line Transect yang dilaksanakan pada bulan Januari-Desember 2018. Nilai indeks keanekaragaman Shannon-Wiener pada transek satu H’ 0,782, transek dua H’1,208 dan transek tiga H’ 1,139. Berdasarkanhasilpenelitianterdapat lima  spesies yang ditemukanya itu Bufo melanostictus, Rana cancrifora, Rana chalconota, Fejevarya limnocharis, dan Hylarana nicobariensis. Berdasarkan kategori indeks Shannon-wiener keanekaragaman amphibi di areal persawahan Tondano termasuk dalam kategori sedangRice fields are good habitat for amphibian life. Amphibians have an ecological function as a counterweight to ecosystems and as an environmental bioindicator. This research tries to analyze the amphibians in the Boleuvard rice field area of Tondano City based on the Shannon-Wiener index value. This study uses the Path Transect method which was carried out in January - December 2018. The index value of the Shannon-Wiener contribution to habitatone H '0,782, habitat two H'1,208 and habitat three H' 1,139. Based on the results of the study found five species found, namely Bufo melanostictus, Rana cancrifora, Rana chalconota, Fejevarya limnocharis, and Hylarana nicobariensis. Based on the Shannon-wiener index category the various amphibians in the Tondano rice field area are included in the medium category
