Abstract

Tujuan dari penelitian ini adalah untuk mengelompokan “site” di sepanjang aliran Sungai Torong Kelurahan Temas, Kota Batu, Jawa Timur berdasarkan komunitas makrozoobenthos yang ditemukan, yang dilakukan pada akhir bulan April 2006-Desember 2006. Proses identifikasi dilakukan di laboratorium Fakultas Perikanan Universitas Brawijaya Malang. Lokasi penelitian terbagi menjadi 16 lokasi pengambilan sampel berdasarkan metode survei. Pengambilan sampel dilakukan dengan menggunakan jaring tangan ukuran 20x30 cm, ukuran mata jaring 500 μm dan dengan teknik kicking sepanjang 10 m di daerah riffle. Analisis data dihitung dengan menggunakan program TWINSPAN guna mengelompokan “site” di sepanjang aliran Sungai Torong menjadi 6 “group of site” (A, B, C, D, E dan F). Berdasarkan analisis data dapat diketahui bahwa taksa yang melimpah hampir diseluruh stasiun pengambilan sampel adalah Chironomus thummi, Tubificidae dan Thiaridae sehingga dapat disimpulkan bahwa Sungai Torong telah mengalami degradasi dan perlu segera direhabilitasi.
