“…Fitoplankton memainkan peranan penting dalam proses fotosintesis (Lee et al, 2014). Fitoplankton merupakan organisme autotrof yang mampu menyediakan makanan sendiri dari bahan anorganik dengan bantuan energi matahari dan kimia (Aryawati et al, 2018). Fitoplankton dapat ditemukan di seluruh massa air, baik permukaan laut hingga di kedalaman tertentu dimana cahaya masih dapat masuk untuk mendorong proses fotosintesis (Nontji, 2002).…”

Adanya aktivitas pembangunan Megaproyek PLTU Batang diduga akan menurunkan kualitas lingkungan perairan khususnya di sekitar Megaproyek PLTU Batang. Salah satu organisme penting bagi ekosistem perairan adalah fitoplankton yang memaninkan perairan dalam produktivitas primer. Fitoplankton adalah mikro organisme autotrof yang dapat dijadikan sebagai indikator kualitas perairan. Tujuan penelitian ini untuk mengetahui struktur komunitas fitoplankton di Perairan Pantai Megaproyek PLTU Batang. Metode penelitian yang digunakan adalah metode deskriptif eksploratif sedangkan penentuan stasiun digunakan metode purposive sampling. Pengambilan sampel dilakukan sebanyak 3 periode waktu pada November 2020 – Februari 2021 di 3 stasiun. Letak stasiun menjorok ke arah laut yaitu dengan stasiun 1 merupakan perairan paling dekat dengan Megaproyek PLTU Batang, stasiun 2 berada di perairan antara Megaproyek PLTU Batang dengan laut dan untuk stasiun 3 berada di laut. Hasil penelitian menunjukkan bahwa terdapat 19 genus fitoplankton berasal dari 2 kelas yaitu 15 genus dari kelas Bacillariophyceae dan 4 genus dari Dinophyceae. Kelimpahan fitoplankton berkisar antara 2.581-10.137 sel/L dengan indeks keanekaragaman 1,61-2,59 tergolong sedang. Indeks keseragaman berkisar antara 0,67-0,99 menunjukkan persebaran merata dan tingkat dominansi rendah. Kandungan nitrat berkisar antara 0,28-0,71 mg/L sedangkan kandungan fosfat berkisar antara 0.08 – 0.74 mg/L sehingga kandungan nitrat dan fosfat di Perairan Pantai Megaproyek PLTU Batang berada di atas baku mutu air laut untuk biota laut. The existence of the Batang PLTU Megaproject development activity is expected to reduce the quality of the aquatic environment, especially around the Batang PLTU Megaproject. One of the important organisms for aquatic ecosystems is phytoplankton. Phytoplankton is an autotrophic organism that can be used as an indicator of water quality. The purpose of this study was to determine the composition, abundance, and community structure of phytoplankton in the Coastal Waters of the Batang PLTU Megaproject. The research method used was descriptive exploratory method while the determination of the station used purposive sampling method. Sampling was carried out for 3 time periods in November 2020 - February 2021 at 3 stations. The location of the stations protrudes towards the sea, with station 1 being the waters closest to the Batang PLTU Megaproject, station 2 being in the waters between the Batang PLTU Megaproject and the sea and for station 3 be at sea. The results showed that there were 19 genera of phytoplankton from 2 classes, namely 15 genera from the Bacillariophyceae class and 4 genera from Dinophyceae. The abundance of phytoplankton ranged from 2,581-10,137 cells/L with a diversity index of 1.61-2.59 classified as moderate. The uniformity index ranged from 0.67-0.99 indicating an even distribution and a low level of dominance. The nitrate content range from 0.28 to 0.71 mg/L while the phosphate content range from 0.08 to 0.74 mg/L so that the nitrate and phosphate content in the Coastal Waters of the Batang PLTU Megaproject is above the sea level for marine biota.

“…Penelitian dilaksanakan pada Bulan September 2021 di sepanjang aliran Sungai Musi bagian hilir Provinsi Sumatera Selatan (Gambar 1). Penelitian dilakukan di bulan September merujuk pada beberapa penelitian di perairan Sumatera Selatan yang memperlihatkan pada bulan Agustus-September, ditemukan kelimpahan fitoplankton yang tinggi (Aryawati, 2016;Aryawati, 2017;Aryawati, 2018).…”

Sungai Musi merupakan sungai terpanjang di Pulau Sumatera yang banyak dimanfaatkan masyarakat sebagai jalur transportasi dan berbagai aktivitas lainnya. Sungai Musi merupakan habitat fitoplankton yang dapat menjadi indikator kualitas perairan. Penelitian ini bertujuan mengetahui kelimpahan, keragaman, keseragaman, dominansi, dan menganalisis potensi HABs fitoplankton di Perairan Sungai Musi bagian hilir. Hasil pengamatan pada 10 stasiun, ditemukan 6 genus fitoplankton dari kelas Bacillariophyceae (Bacillaria, Coscinodiscus, Ghemponema, Navicula, Skeletonema, Strepthotecha), 6 genus dari kelas Chlorophyceae (Chlorella, Hydrodiction, Micrasterias, Pediastrum, Platydorina, Spirogyra), 1 genus dari kelas Cyanophyceae (Oscillatoria). Hasil analisis diperoleh kelimpahan sebesar 10-483 sel/L, indeks keanekaragaman (H’) 0,89-1,57, indeks keseragaman (E) 0,75-0,99, dan indeks dominansi (C) 0,25-0,46 dengan genus fitoplankton di kelimpahan tertinggi Spirogyra dan terendah Bacillaria. Hasil pengamatan menunjukkan parameter fisika-kimia termasuk kategori baik untuk pertumbuhan fitoplankton dan ditemukan beberapa jenis fitoplankton yang berpotensi HABs (Coscinodiscus, Skeletonema, Oscillatoria). The Musi River, the longest river on the island of Sumatra, is widely used by the community as a transportation route and for various other activities. Therefore, the Musi River is a habitat for phytoplankton and can be a bioindicator of water quality. This study aims to determine the success of analysing the abundance, diversity, uniformity, dominance and potential of HABs phytoplankton downstream of the Musi River. Observations of 10 sampling stations found six genera from the class Bacillariophyceae (Bacillaria, Coscinodiscus, Ghemponema, Navicula, Skeletonema, Streptotheca), six genera from the class Chlorophyceae (Chlorella, Hydrodiction, Micrasterias, Pediastrum, Platydorina, Spirogyra), one genus class Cyanophyceae (Oscillatoria). The results of the analysis obtained an abundance of 18-483 cells/L, the diversity index (H') 0.89-1.57, uniformity index (E) 0.75-0.99, and dominance index (C) 0.25-0.46 with the phytoplankton genus in the highest abundance of Spirogyra and the lowest Bacillariophyceae. Furthermore, the results of the observations show that the physicochemical parameters are in a suitable category for phytoplankton growth and found several types of phytoplankton that have the potential for HABs (Coscinodiscus, Skeletonema, Oscillatoria).

The Musi River is the largest and longest river in South Sumatra. The development of population activities in the Musi River Basin can affect river water quality and can cause pollution. The high level of industrial activity and households along the Musi River causes a decrease in environmental quality in the Musi River Basin. Based on this, further research is needed to determine the extent of pollution in the Musi River Basin. The purpose of this study is to assess saprobitas along the Musi River Basin based on SI (Saprobic Index) and TSI (Tropical Saprobic Index) values, and knowing the level of water pollution using saprobitas water assessment. This study uses plankton as the main material, namely water samples and plankton samples. This study uses an exploratory design with survey methods, and the determination of sampling stations by purposive sampling method. The results showed abundance of phytoplankton in the waters of the Musi River in the range of 123 - 2581 cells / liter or an average of 1397 cells / liter, the waters of the Musi River can be categorized as Oligotrophic waters with several station points that can be categorized as Mesotrophic waters. The Saprobic index in the waters of the Musi River ranges from 0.63 - 1, classified in the phases of the microbial, namely β-Mesosaprobic, so that the waters of the Musi River are classified as mild or low.
