Abstract

Penelitian ini bertujuan untuk mengetahui jenis mikroalga dari tiga macam kolam di kecamatan Pamulutan, Kabupaten Ogan Ilir serta macam jenis yang dapat tumbuh setelah diisolasi dengan medium BG-11 (Blue green-11) dan mendeskripsikan karakteristik isolat mikroalga tersebut. Penelitian ini menggunakan metode deskriptif dengan metode penentuan sampling secara purposive sampling memperhatikan karakteristik warna dan letak geografis kolam. Teknik pencuplikan dengan composite sampling yang diambil 10 liter 10 kali. Waktu pengambilan sampel dilakukan pada bulan November-Desember 2019. Sampel diidentifikasi di laboratorium pendidikan biologi FKIP Unsri Indralaya, jumlah jenis dihitung menggunakan SRCC (Sedwich Rafter Counting Cells). Hasil identifikasi menunjukkan bahwa terdapat 12 spesies yang ditemukan. Mikroalga yang dapat tumbuh pada medium isolasi ada 2 spesies yakni Microcystis aeruginosa pada kolam 1 dan Euglena viridis pada kolam 3. Sedangkan mikroalga yang tidak berhasil tumbuh ada 10 spesies yakni Scenedesmus, Euglena, Coleastrum, dan Pediastrum pada kolam 1, pada kolam 2 yang tidak tumbuh Scenedesmus, Pediastrum, Tetraedron, dan Ceratium, kolam 3 yang tidak tumbuh Staurastrum dan Scenedesmus. Karakteristik isolat dari jenis mikroalga yang tumbuh berbeda-beda ditinjau dari isolat sel dibawah pembesaran mikroskop binokuler yang diamati dari bentuk dan ukuran serta warna sebagai karakteristik pendukung. Bentuk isolat setelah diamati dengan mikroskop binokuler beragam dengan ukuran bervariasi yakni 5 µm-10 µm. Kata kunci : Isolasi, mikroalga, kolam kabupaten Ogan Ilir. This study aims to determine the types of microalgae from three kinds of ponds in Pamulutan sub-district, Ogan Ilir Regency and the types that can grow after being isolated with BG-11 (Blue green-11) medium and describe the characteristics of the microalgae isolates. This study uses a descriptive method with a purposive sampling method to determine the color characteristics and geographic location of the pond. Sampling technique with composite sampling taken 10 liters 10 times. The sampling time was carried out in November-December 2019. The samples were identified in the biology education laboratory of FKIP Unsri Indralaya, the number of species was calculated using SRCC (Sedwich Rafter Counting Cells). The identification results showed that there were 12 species found. There were 2 species of microalgae that could grow on isolation medium, namely Microcystis aeruginosa in pond 1 and Euglena viridis in pond 3. Meanwhile, 10 species of microalgae that failed to grow were Scenedesmus, Euglena, Coleastrum, and Pediastrum in pond 1, in pond 2 which did not. grows Scenedesmus, Pediastrum, Tetraedron, and Ceratium, pool 3 which does not grow Staurastrum and Scenedesmus. Characteristics of isolates from different types of microalgae that grew in terms of cell isolates under binocular microscope magnification were observed from the shape and size and color as supporting characteristics. The shape of the isolates after being observed with a binocular microscope varied with varying sizes, namely 5 µm-10 µm. Keyword :Isolation, microalgae, Ogan Ilir disctrict ponds.
