Abstract

INDONESIA Penelitian ini dilakukan untuk mengetahui biodiversitas fitoplankton penyebab harmful algae blooms (HABs) di Teluk Gerupuk Kab. Lombok Tengah. Metode pengambilan sampel menggunakan metode purposive sampling. Dasar penentuan lokasi sampel pada penelitian ini adalah keberadaan keramba jaring apung di 5 titik pengamatan yang sudah ditentukan. Penelitian ini dilaksanakan pada bulan Desember pada minggu ke 1. Dan pengambilan sampel air dilakukan pada pagi hari (08.00-11.00 WITA). Penelitian ini dilakukan dalam dua tahap, yaitu tahap pengambilan sampel di lapangan dan tahap pengamatan di laboratorium. Jumlah yang ditemukan pada 5 stasiun berjumlah ialah berjumlah 6 kelas yaitu Bacillariophyceae, Mediophyceae, Coscinodiscophyceae, Cyanophyceae, Dinophyceae, yang terbagi kedalam 3 filum yaitu Bacillariophyta, Cyanophyta, dan Miozoa. Tingkat keanekaragaman fitoplankton di Teluk Gerupuk tergolong sedang. Tingkat indeks kemerataan (E) fitoplankton menunjukkan bahwa penyebaran setiap takson fitoplankton cenderung sama, Nilai indeks dominasi (D) menunjukkan tidak ada spesies fitoplankton yang mendominasi. INGGRIS This research was conducted to determine the biodiversity of phytoplankton that could potentially cause harmful algae blooms (HABs) in Gerupuk Bay District. Central Lombok. The sampling method uses purposive sampling method. The basis for determining the sample location in this study is the existence of floating net cages at 5 predetermined observation points. This research was conducted in December in week 1. And water sampling was carried out in the morning (08.0011.00 WITA). This research was conducted in two stages, namely the sampling stage in the field and the observation stage in the laboratory. The number found in 5 stations amounted to 6 classes namely Bacillariophyceae, Mediophyceae, Coscinodiscophyceae, Cyanophyceae, Dinophyceae, which were divided into 3 phyla namely Bacillariophyta, Cyanophyta, and Miozoa. Phytoplankton diversity level in Gerupuk Bay is classified as moderate. The level of evenness index (E) of phytoplankton indicates that the distribution of each phytoplankton taxon tends to be the same. The dominance index value (D) indicates that no phytoplankton species dominates.
