“…Hydrophyte species that always found were free-floating species (Eichornia crassipers and Salvinia molesta), and Chrysophyta for periphyton. The composition of periphyton plankton in freshwater ecosystems is less than marine ecosystems (Dodson et al, 2009;Rahayu et al, 2013;Widyarini et al, 2017, Dharmaji et al, 2021. In this study, it was seen that the composition of the phylum Chrysophyta dominated its spread more than Chlorophyta and Cyanobacteria (Table 1).…”

“…Attach to the substrate, periphytons have various sticking devices, namely: (1) Rhizoids, as in Oedogonium and Ulothrix; (2) Long or short gelatinous stalks, as in Cymbella, Gomphonema and Achnanthes and (3) Sphaerical gelatinous pads reinforced with lime or not, as in Rivularia, Chaetophora and Ophyrydium. The type of Ciliophora periphyton that acts as a zooplankton found around the Negara river fish cages was lower than the Barito Marabahan River, and the highest was in the waters of the Bangkau swamp (Dharmaji et al, 2020;Dharmaji et al, 2021).…”

Hydrophytes are the group of spermatophytes that reproduce vegetatively, and multiply twice as much in 7 until 10 days, and have special organs that are could be adapted to the aquatic environment (Suwasono, 1996; Afiyah et al., 2020). Massive increase in hydrophytes in Negara rivers could be reduce fish resources, hinder water transportation, fishery activities, sedimentation, and purification that stimulates the growth of other plants (Nurfitri et al., 2011; Chen et al., 2014; Grand-Clement et al.,

“…Uniformity is the diffusion of different genera that gained from the diversity connected [19]. [20], the dominance index of a genus in waters is actually influenced by environmental effect to provide good and worst dominance index values found. If the uniformity is smaller than others value, it would show that the distribution of the quantity of individuals and no species dominates.…”

Microalgae as phytoplankton become the considerable attention object because of their potential in various application. Microalgae can be discovered in various ecosystems and growing in all environmental conditions. The purpose of this study was to identify the genus and abudance of microalgae in some of the coastal area of Sumatera Island, Indonesia. This study was conducted in August until September 2022. The method used is descriptive quantitative by exploration and microalgae calculations. The calculations based on Shannon-Wiener such as abundance, relative abundance, diversity index, uniformity index and dominance index. The sampling area selected was carried out in Suak Ribee Beach (Aceh), Gandoriah Beach (Padang) and Lengkuas Island (Belitung). The sampling method used the random sampling method by horizontal sampling. Statistical analysed is NMDS (non metric multidimensional scaling). The results obtained were 4 class, namely Bachillariophyceae, Chlorophyceae, Cyanophyceae, Fragilariophyceae and 21 genera, namely Achnanthes, Anabaena, Aphanocapsa, Bacillaria, Chalamydomonas, Chroococcus, Cocconeis, Diploneis, Encynopsis, Eudorina, Eupodiscus, Fragilaria, Gyrosigma, Hyalodiscus, Navicula, Nitzschia, Oocytis, Parlibellus, Peronia, Stauroneis and Ulothrix. Microalgae was dominated by group of Bachillariophyceae (76%). The abudance of microalgae obtained range from 11.117 – 36.442 cells/L. The results showed that the diversity index value was moderate (1,46), low dominance (0,17) and moderate uniformity (0,48).

“…These micro-organisms are attached to surfaces submerged in water, some of which are found in wood, stone and plants. Periphyton serves as a food source for small consumers such as invertebrates and fish [8,9]. The growth and development of periphyton is supported by a good substrate.…”

Many activities are carried out around the Laut Tawar lake, one of which is the cultivation of floating net cages that can contribute nutrients to the waters. One of the organisms that can take advantage of the abundance of nutrients in the waters is periphyton. This study aims to examine the community structure of periphyton as natural food in Laut Tawar Lake. This research was conducted in January-April 2022. The results showed that there are 9 classes of periphyton at the KJA station, namely Bacillariophyceae, Chlorophyceae, Cyanophyceae, Rhizopoda, Dinophyceae, Euglenophyceae, Trebouxiophyceae, Klebsormidiophyceae and Coscinodiscophyceae. While, at non-KJA stations there are 7 classes where the Klebsormidiophyceae class and the dinophyceae class are not found at non-KJA stations. The highest abundance at the KJA station was on the 7th day with a value of 108,655 cells/cm2 and non-KJA was 24,552 cells/cm2. The lowest abundance occurred on day 14 at both stations. Periphyton diversity index at KJA and non-KJA stations ranged from 1.88-2.76, which was moderate. The evenness index of periphyton species ranging from 0.61-0.75 was classified as high, while the dominance index ranging from 0.09-0.24 was classified as low. Based on the values obtained, the community structure of periphyton on artificial substrates in the KJA and non-KJA areas in Laut Tawar Lake experienced moderate ecological stress with the community in a stable condition. The t-test results obtained that the abundance values at KJA stations and non-KJA stations had the difference that the abundance of periphyton at KJA stations was greater than at non-KJA stations.
