“…consists of cells that are cylindrical in shape and arranged lengthwise like threads. This algae lives in fresh water where the water is not too warm and lives attached to rocks or at the bottom of the water [10]. On the other hand, spring water also has sufficient nutrients for microalgae growth, although not as much as river water.…”

Microalgae are protists with eukaryotic cell structures which can be found in aquatic ecosystems such as rivers, lakes, reservoirs, ponds, and oceans. The protist culture method can be considered as a technique to allow protists to grow in a certain controlled environment. The objective of this study was to determine the growth of microalgae in the different water sources A modified closed photo-bioreactor (bottle) was used in this research. The number of experiments was 130, each experiment comparing 5 different natural water resources which are well, pond, pool, paddle, river, tap water, and mineral water and tap water as control, all with 25 replications. Those bottles were put under the sun for 2 weeks. Every day, the colour changes were documented. The result showed that within 2 weeks, no colour changes for mineral and tap waters. On the fourth and fifth days, the watercolour of rivers, ponds, paddle, pools turn the greenish or murky brownish. This indicated the growth of microalgae in the bottle. The different colour indicates the different species or a group of species. This simple experiment able to be developed for practical work during pandemic Covid-19, when students have to study at home, but are still able to get their competence by small project-based learning.

“…Large puddles are likely to be overgrown with microorganisms or micro-algae and waters with calmer and less heavy currents like rice fields will allow the presence of micro-algae. The low current velocity in water causes a high abundance in the class Chlorophyceae, namely green algae [10,21].…”

“…Kelimpahan fitoplankton dari divisi Chlorophyta (alga hijau) di Danau Kenanga Universitas Indonesia sangat tinggi. Hal ini dikarenakan Chlorophyta merupakan kelompok terbesar dari vegetasi alga yang sebagian besarnya hidup di air tawar terutama di perairan yang mendapat pencahayaan yang cukup seperti di kolam, danau, genangan air hujan, dan pada aliran air seperti sungai dan selokan (Fauziah & Laily, 2015). Secara umum, komposisi fitoplankton yang didapat didominansi oleh kelompok Chlorophyta (alga hijau) dan diikuti oleh kelompok Cyanophyta (alga hijau-biru).…”

In addition to urban forest area at the University of Indonesia, Depok Campus, West Java, there are lakes that functions as water reservoir area. University of Indonesia is eager to create green and beautiful campus environment with one of its efforts is to care for the lake ecosystem in the campus. This study was conducted to analyze the diversity of phytoplankton in the lake. Sampling was carried out by determining 3 location points with 3 times repetitions conducted on different days. The water samples taken were then identified at the Biology Laboratory FMIPA UNJ. The mean values of water quality parameters obtained were pH 10, TDS 90 ppm, temperature 30°C, and water clarity 46 cm. The results showed that 14 genera and 20 species have been found, they are Chlorophyta, Chroococcus, Coelosphaerium, Crucigeniella, Euglena, Gloeocapsa, Merismopedia, Pediastrum (3 species), Peridinium, Scenedesmus (4 species), Tablelaria, Tetrastrum, Volvox, and Westella (2 species). The Diversity Index Shannon-Wiener during the observation was 2.9, which means that the condition of water at the University of Indonesia Lake was very good and not polluted. The availability of phytoplankton in the area was generally sufficient which can be utilized by other organisms as food source.

“…Spesies tersebut termasuk ke dalam Divisi Chlorophyta. Chlorophyta adalah produsen utama daIam ekosistem perairan yang dapat meningkatan produktivitas primer suatu perairan [5]. Adanya perbedaan jenis yang ditemukan pada masingmasing stasiun dapat dipengaruhi oleh faktor tata letak lokasi yang dijadikan sebagai titik sampling.…”

Penelitian telah dilaksanakan di Ranu Klakah, Kabupaten Lumajang, Jawa Timur. Tujuan dari penelitian ini adalah untuk mengetahui komposisi jenis dan kelimpahan relatif fitoplankton di perairan Ranu Klakah, Kabupaten Lumajang. Stasiun pengambilan sampel ditentukan pada tiga titik yakni inlet, tengah (kawasan KJA), dan outlet. Pengambilan sampel dilakukan sebanyak 3 kali. Parameter yang diamati meliputi parameter fisika, kimia dan biologi. Parameter fisika dan kimia perairan yang diamati meliputi suhu, kecerahan, pH, DO, nitrat serta orthofosfat. Divisi fitoplankton yang ditemukan memiliki spesies terbanyak adalah Chlorophyta, Chrysophyta, dan Ochrophyta. Tetraspora sp yang termasuk divisi Divisi Chlorophyta memiliki kelimpahan yang paling tinggi jika dibandingkan dengan jenis spesies plankton lainnya. Data kualitas air diperoleh suhu perairan berkisar 27,6 -28 o C, kecerahan peraiaran berkisar 60 cm -119 cm, nilai pH peraiaran 7, oksigen terlarut berkisar 7 -7,8 mg/l, nitrat berkisar 0,23 -1,04 mg/l, sedangkan orthofosfat didapatkan nilai 0,1 mg/l. Berdasarkan hasil penelitian yang telah dilaksanakan dapat disimpulkan bahwa wilayah perairan Ranu Klakah masih tergolong dalam perairan mesotrofik (perairan yang tingkat kesuburan sedang). Berdasarkan dari komposisi jenis dan kelimpahan fitoplankton dapat disimpulkan bahwa keanekaragaman jenis yang dimiliki Ranu Klakah masih tinggi.
