Abstract

Penelitian tentang Studi Struktur Komunitas Fitoplankton di Perairan Sungai Musi Bagian Hulu telah dilakukan di bulan April dan Juni 2007. Penelitian ini bertujuan untuk mengetahui kelimpahan dan mengidentifikasikan keberadaan fitoplankton di perairan Sungai Musi bagian Hulu. Pegambilan sampel sendiri dilakukan dengan metode “Purposive Random Sampling” dengan 10 stasiun. Parameter lingkungan yang diukur meliputi suhu, kecerahan, kecepatan arus, kedalaman sungai, pH, dan DO. Data dianalisis untuk mengetahui kelimpahan, indeks keanekaragaman, indeks dominansi, indeks kesamaan. Hasil penelitian diperoleh 26 genera fitoplankton terdiri atas 3 kelas yaitu; 15 genera Bacillariophyceae, 6 genera Chlorophyceae, dan 5 genera Cyanophyceae. Frekuensi kehadiran tertinggi adalah Oscilatoria, kelompok fitoplankton yang banyak ditemukan antara lain : Synedra, Diatoma, Navicula, Oscilatoria, dan Gyrosigma. Indeks keanekaragaman fitoplankton pada bulan April dan Juni 2007 rata-rata hasilnya adalah 1<H’ terdapat pada stasiun Padang Tepong dan Cawang Lamo atau keanekaragaman rendah. Indeks dominansi pada bulan April dan Juni 2007 dengan nilai C<0.5 atau ditemukan marga fitoplankton yang tidak mendominasi di perairan sungai musi bagian hulu Kata kunci :fitaplankton, sungai musi, hulu, struktur komunitas
