Abstract

Teluk Buo mangrove forest is one of tourist destination in the Sumatera BaratProvince. The input of pollutant originated from anthropogenic activities, however,reducing the water quality and as a consequence negatively affects the mangroveecosystem as well as the associated organisms, including bivalves. To understand thecommunity structure of bivalves in the mangrove ecosystem, a research wasconducted on February 2017. The observation of bivalve community is done bymaking line transects. There were 3 transect lines and in each line, 9 sub plots (1x1m)observed. The bivalves present in the plots were collected manually everyday for 2weeks period. Results shown that there were 6 bivalves species present, they wereGeloina erosa, Anadara antiquata, Barbatia sp., Lucinoma galathea, Chameleastriatula and Trychardium sp. with bivalves abundance was ranged from 6,667 to31,481 organisms/ha. The value of diversity index (H’) was 0.2650-2.403, thedominance index (C) was 0.210-0.722 and the uniformity Index (E) was 0.059-0.563.The bivalva community structure in Teluk Buo is moderate with the dominant species(Geloina erosa) has been disturbed by the existence of ecological pressure and thedominant species causing unbalanced mangrove area. Abiotic environmental factorsinclude temperature was 29-31 0C; pH of water was 7.3-7.5, soil pH 7.1-7.2 andsalinity was 25-340/00.Key words: Bivalves, Mangrove Ecosystem, Teluk Buo, Water Quality

Abstract

Teluk Buo mangrove forest is one of tourist destination in the Sumatera Barat Province. Thet forest, however mostly inhabit by seedlings, while trees are scarce. This condition may affect the mangrove litter production. A research aims to understand mangrove litter production in Teluk Buo was conducted on February 2017. The litter was collected using a net (1x1 m) that was set under the canopy, around 2 meters height from the forest floor. The net was set for 21 days and once/ 7 days, the litter was removed. The collected litter was then dried in the oven 105OC for 24 hours. The leaves, propaguls and twigs were separated and weighed. Total mangrove litter production average was 7.87 g/m2/day. The leaf is the main component of the litter in mangrove (7.03 g/m2/day), followed by propagules (0.26 g/m2/day) and twigs (0.58 g/m2/day).Keywords: leaves, forest, canopy

Abstract

Sail River is one of the most polluted river in Pekanbaru. A study aims to understand the physical, chemical and biological condition of water quality in the river was conducted from February to Mai 2015. The biological condition of the water was analyzed based on type and population of macrozoobenthos present in the river. Parameters measured were temperature, depth, transparency, turbidity, current speed, TSS, pH, DO, BOD, COD, nitrate and phosphate content. Data were analyzed using the NFS-WQI and FBI method. Results shown that the macrozoobenthos present in the Sail river were consisted of 3 phylum and 6 family, namely Annelid (Tubificidae), Arthropod (Chironomidae), and Mollusks (Ampullidae, Bithyniidae/ Bulimidae, Thiaridae). The water quality parameters in the Sail River are as follow: temperature 29-30oC, depth 0.21-0.56 m, transparency 6.45-15.27 cm, turbidity 112-593 NTU, current speed 8.08-26.58 cm/s, TSS 44.00-173.67 mg/L, pH 5-6, DO 2.80-11.51 mg/L, BOD5 4.77-29.12 mg/L, COD 10.67-44.80 mg/L, nitrate 0.18-0.81 mg/L and phosphate 1.06-1.71 mg/L. Based on NSF-WQI result, the water quality in the Sail River was categorized as poor to very poor (27.97-14.68), while the FBI value (8-8.72) indicates that the river was badly contaminated.Keyword: Sail River, water quality, NSF-WQI, Family Biotic Index, Macrozoobenthos

Abstract

Abstract Bivalva is a types of aquatic organism that lives in mangrove ecosystems.                             This research aims to determine the types and density of bivalve in the mangrove ecosystem of Sungai Asam Village. The research has been conducted on July to August 2020. There were 3 stations set, St1 is a mangrove forest area that is relatively natural and far from residential area, St2 was in the mangrove forestwhich is used as a tourist destination and St3 was in the mangrove forest that has residential area. Each station 3 plots/station and 3 subplots/plot. In each subplot (1x1m2), the bivalve were collected by hand. Results shown that there were 3 species of bivalve, namely Polymesoda erosa, Geloina expansa, Pharella acutidents with density was  6.296-41.852 organisms/ha. The density of mangrove trees in Sungai Asam Village is categorized as damaged. There is a close relationship between mangrove tree and bivalve densities. Keyword : Aquatic organisms, Geloina expansa, Mangrove forests,Pharella acutidents, Polymesoda erosa

Abstract

Abstract The mangrove ecosystem of the village of Rawa Mekar Jaya has been degraded due to illegal logging. The condition of water quality is influenced by various activities that take settlements, sago processing coastal activities of tides that cause changes in water salinity. This research was conducted in July 2019 in the mangrove/estuary ecosystem of the Rawa Mekar Jaya river. The purpose of this study was to determine the distribution patterns of giant prawns in the mangrove ecosystem of Rawa Mekar Jaya Village. There are 3 research stations (50x50m2). Taking sampling using rowing boats and fishing gear with hooks 3. This research every day for 1 week.Sample observed in the laboratory of Fisheries Biology in Fisheries and Marine Faculty Universitas Riau. The observations made were meristic, morphometric and distribution index calculations. Research data were analyzed descriptively. The results showed there were differences in the distribution patterns of shrimp at each station. Stations 1 and 2 of shrimp distribution are uniform, while at station 3 distribution of shrimps is random. The measurement results of sample was found with total shrimp length (PTO) ranges from 110-250 mm, with an average of 176 mm and total body weight (BTO) ranging from 31-140 g with an average of 83.5 g. Shrimp caught during the study female were adult and juvenil, and which indicated that the mangrove ecosystem was a place of spawning for giant prawns.Keywords: Giant prawns Distribution, Mangrove Ecosystem, Water Quality, Rawa Mekar Jaya

Abstract

Abstract Phytoplankton was sensitive to the environmental changes, and therefore it might be used as bioindicator. A research aims to understand the diversity of phytoplankton in the swamp area of  the Sawah Village was conducted on July to August 2018. There were 3 stations with 3 sampling points in each station. Samples were taken 3 times, once/week, in 3 different stations, namely S1 (natural area), S2 (residential area), S3 (around the plantation area). Water quality parameters measured were temperature, brightness, dept, pH, dissolved oxygen, CO2, nitrate and phospate. Phytoplankton found were consisted of 32 species that were belonged to 3 classes, namely Bacillariophyceae (7species), Chlorophyceae (12species) and Cyanophyceae (11 species). Phytoplankton abundance ranged from  662–3,266 cells/L,  the species diversity index (H') ranges from 2,7659–3,5726, the dominance index (C) ranges from 0,1161–0,1963 and uniformity index (E)  ranges from 0,874 – 0,8122. Water quality parameters values were as follows:  temperature 25 - 270C, pH 4 - 5, dissolved O2was 3.7-3.8 mg/L, CO2 was 1.7-2.7 mg/L, nitrate was 0.171 - 0.231 mg/L, and phosphate was 0.144 - 0.219 mg/L.Keywords:    Uniformity index, Black water, Peat swamp,Bacillariophyceae, Chlorophyceae

Abstract

A study aims to understand the community structure of mangrove that grow in the SungaiAlam village, Riau has been conducted from January to February 2014. Sampling was doneusing a line plot sampling method. Mangrove in the sampling sites were divided in to seedling,sapling, poles and trees. Mangroves were identified based on Rusila at al (2006), Bengen (2001)and Saparinto (2007). While data were analized following English, Wilkinson, and Baker (1994).Results shown that there were 10 mangrove types (8 families) present in the samplingarea they were Avicennia alba, Sonneratia alba, Acanthus ilicifolius, Acrostichum speciosum,Rhizophora mucronata, Rhizophora stylosa, Rhizophora apiculata, Nypa fruticans, Lumnitzeraracemosa and Xylocarpus granatum. The dominant species in the research area is Rhizophoraspp. Mangrove distribution on this research influenched by sediment types. Mangrove vegetationdominated by Avicennia spp. and Sonneratia spp. in the deep muddy area. While in the shallowmuddy area, it was dominated by Rhizophora spp. In the dry area Xylocarpus spp., Rhizophoraspp., and Nypa spp. were dominant. Shannon and Winner index of the mangrove ranged from0,66-1,92 and dominancy index (C) ranged from 0,36-0,1. Temperature ranged 28-30oC, land pH6, water pH ranged 6-7, and salinity ranged 21-22o/oo.Keyword : Mangrove, Community structure, Sungai Alam Village
