Abstract

ABSTRACTPeriphyton is a sessile microscopic organism that attach on certain substrate. A research aims to understand types and abundance of periphyton attached in the lotus leaves present in the Bandar Kayangan dam, Pekanbaru has been conducted Februari 2019. There were 3 stations, around floating caged fish culture (Station 1), in the water closed to teak plantations (Station 2) and in the recreational area (Station 3). Samplings were conducted 3 times, once/week. Lotus leaves were collected and periphytons were obtained through scraping upper and lower surface of the leaf (5 ×5 cm). Periphyton collected were preserved using Lugol 1% and then were indentified. Result shown that there were 24 periphyton species present and they were belonged to classes, Cynanophyceae (3 species), Chlorophyceae (5 species), Bacillariophycea (11 species), and Euglenophyceae (1 species). Abundance of the periphyton ranged from 2,317-2,621 cells/cm2, diversity index was 4.148-4.242 and dominancy index was 0.054-0.060. Based on data obtained, it can be concluded that the Bandar Kayangan dam water was fertile..Keywords:lotic, sessile organism,  natural substrats, trophic state

Abstract

AbstractSeagrass ecosystem in the Madong Bay is inhabited by numerous aquatic organisms, including gastropods. A research aim to determine the community structure of gastropds in the seagrass ecosystem has been conducted on July – August 2019. Data was collected from 3 stations, there were 2 line transects in each station. In each line there was 4 quadrats (1m x 1m). Gastropods present inside the quadrat were collected manually. Results shown that there was 9 species of gastropods, namely Pirenella cingulate, Cerithium coralium, Drupella margariticola, Nassarius canoldalis, Nerita lineata, Pugilina cochilidium, Strombus canarium, Strombus urceus and Trochus maculatus. The diversity index (H’) was 1.99 – 2.49 (medium), uniformity index (E) was 0.77 – 0.83 (high) and dominance index (C’) was 0.32 – 0.22.  Keywords :Pirenella cingulate, diversity index, uniformity index, dominance

Abstract

                    ABSTRAC  Pariaman Regency coastal area is affected by current and tide from Indian Ocean that contribute the presence of microplastic in that area. To understand the microplastic types and density, a research has been conducted in May-July 2019. There were 3 sampling sites (Pantai Mangguang, Pantai Ampalu and Pantai Gandoriah) and there were 3 plots (50x50 cm) placed in each site. Sediment inside the plot was scrapped 5 cm depth. The sediment was then sieved (5 and 1 mm mesh size), dried and soaked in 35% NaCl. The floating microplastics were then collected and identified using a dissecting microscope. Results shown that there were 4 types of microplastic present, they were film, fragmen, fiber and foam. The most common microplastic found was film (1,360item/m3). The density of microplastic found in the sampling site ranges from 400 - 1,840 item/m3. In the intertidal zone, the highest density of microplastic was found in the highest tidal level (2000 item/m3). Keywords: Plastic Pollution, Intertidal Zone, Sediment, Film.

Abstract

The Kampar River received pollutants originated from anthropogenic activities along the river and thus negatively affect the water quality in general. To understand the water quality of the river based on periphyton community structure and WQI-NSF Index, a research was conducted from January to March 2017. There were five (5) sampling points. Water samples were taken 3 times/ week. Water quality parameters measured were temperature, turbidity, transparency, current speed, total suspended solid, depth, pH, DO, BOD5, nitrate, phosphate and types of periphyton present. Results shown that there were 5 classes of periphyton present, namely Cyanophyceae (8 species), Chlorophyceae (16 species), Bacillarophyceae (18 species), Xantophyceae (2 species) and Euglenophyceae (2 species). Water quality parameters are as follows : Temperature 30.3-310C, turbidity 8.1-11.22 FTU, transparency 61.25-79 cm, current speed 25-36 cm/s, TSS 10.3–16.17 mg/L, TDS 11.17– 16.75 mg/L, depth 17-138 cm, pH 5–5.17, dissolved oxygen 5.47– 6.23 mg/L, BOD5 2.59–3.38 mg/L, nitrate 0.0822-0.1803 mg/L and phosphate 0.4352-0.4823 mg/L. The value of the WQI-NSF index was 62-66, indicates that the river is on moderate condition.Keywords : Kampar River, Water Quality, WQI-NSF, Periphyton

Abstract

This research was conducted from January-February 2014 in Sungai Alam Village,Bengkalis Sub District, Bengkalis Regency, Riau Province. The aim of research is tounderstand the relationship between mangrove density with abundance of bivalva.The result showed that 7 species of mangrove were found: Avicennia alba,Sonneratia alba, Rhizopora apiculata, R. mucronata, R. stylosa, Lumnitzera racemosa,Xylocarpus granatum. Density of mangrove between 2.834-4.233 trees/Ha. In eachstation, there were 2 kinds of bivalva such as Polymesoda expansa and Pharus sp. Theabundance of bivalva between 834 – 2.000 organism/Ha. The highest abundance wasobtained in the 3rd stasion (2000 organism/Ha), while the lowest was obtained in the 1ststation (834 organism/Ha). To found out relation between mangrove density and bivalvaabundance, the data were analized by using simple linier regretion. The regression line testbetween mangrove density with abundance of bivalva showed the equation Y= 272,3 +0,194 X with determine coefisien (R2) is 0,266 or 26,6 %.Keywords : Mangrove density, bivalva abundance, Sungai Alam, Bengkalis, Riau

Abstract

AbstractMangrove serve as habitat for mangrove snail, including Cerithidea quadrata. Aresearch aims to understand the relationship between mangrove density and the abundance of mangrove snails (C. quadrata) has been conducted from May to July 2020 in the Sungai Asam Village, Indragiri Hilir Regency. A purposive sampling method was applied. There were 3 observation stations, and in each stations there were 3 transect lines. In  each transect line, there were 3 observation plots (10 x10 m) with 5 subplots (1x1 m) in each plot. The relationship between mangrove density and the abundance of mangrove snails was analyzed using a simple linear regression. The density of mangroves was around 844.44–1,100.00 (trees/ha), while the abundance of mangrove snails ranges from 6,222.22 to 13,333.33 (organisms/ha). Results shown that there was a very strong relationship between the mangrove density and snail abundance. The environmental condition in general is good and able to support the life of the mangrove snail. Keywords: Mangroves, gastropods, environmental parameters and Asam River
