Abstract

ABSTRAKFitoplankton memiliki peranan penting dalam suatu perairan yaitu sebagai dasar rantai makanan dan bioindikator kesuburan perairan. Tujuan dari penelitian ini adalah untuk mengetahui jenis-jenis fitoplankton dan kelimpahan fitoplankton diperairan kawasan teluk dan pelabuhan. Penelitian ini dilaksanakan pada bulan Desember 2018 - Januari 2019 di Kalianget Kabupaten Sumenep. Proses pengambilan sampel dilakukan pada 2 stasiun 6 titik dengan menggunakan alat planktonet berukuran 10 mikron dan melakukan pengamatan mikroskop. Hasil penelitian diperoleh 20 genus dari 3 kelas fitoplankton yaitu Dinophyceae (3), Bacillariaphyceae (16) dan Cyanophyceae (1). Nilai kelimpahan fitoplankton pada stasiun 1 berkisar 875 ind/l sampai 9.125ilai kelimpahan fitoplankton pada stasiun 1 berkisar 875 ind/l sampai 9.125 ind/l. Pada stasiun 2 berkisar 2.875 ind/l sampai 45875 ind/l sampai 4.500 ind/l. Ditinjau dari indeks keanekaragaman, keseragaman dan dominansi pada fitoplankton dapat menunjukkan bahwa fitoplankton diperairan Kalianget relatif stabil dan tidak ada yang mendominansi.Kata Kunci: Kelimpahan, Fitoplankton, KaliangetABSTRACTPhytoplankton has an important role in waters, namely as the basis of the food chain and bioindicator of water fertility. The purpose of this study was to determine the types of phytoplankton and the abundance of phytoplankton in the waters of the bay and harbor area. This research was conducted in December 2018 - January 2019 in Kalianget, Sumenep Regency. The sampling process was carried out at 2 stations 6 points using a 10 micron planktonet instrument and conducting microscopic observations. The results obtained 20 genera from 3 phytoplankton classes, namely Dinophyceae (3), Bacillariaphyceae (16) and Cyanophyceae (1). The abundance value of phytoplankton at station 1 ranged from 875 ind / l to 9,125 ind / l. The abundance value of phytoplankton at station 1 ranged from 875 ind / l to 9,125 ind / l. At station 2 the range is 2,875 ind / l to 45875 ind / l to 4,500 ind / l. Judging from the diversity index, uniformity and dominance of phytoplankton, it can show that the phytoplankton in Kalianget waters is relatively stable and nothing dominates.Keywords: Abundance, Phytoplankton, Kalianget
