Abstract

A study on the diversity of phytoplankton in the Solok Pulau Lake was conducted fromOctober–December 2015. This research aims to understand the diversity and abundance ofplankton in that area. There were three stations with 3 sampling points in each station. Sampleswere taken 3 times, once a week and they were analyzed in the Aquatic Productivity Laboratoryoh the Fisheries and Marine Science Faculty, Riau University.Result shown that the phytoplankton obtained were consist of 22 species, they werebelonged to of 6 classes, Bacillariophyceae (4 species), Chlorophyceae (10 species),Cyanophyceae (3 species), Dinophyceae (1 species), Euglenophyceae (3 species) danXantophyceae (1 species). The average of phytoplankton abundance was around 553 – 17.778cells/l. The most common phytoplankton was Isthmia sp. (28.978 cells/L, Bacillariophyceae).Diversity index (H’) was 2.47 – 3. 54 and dominancy index (C) was 0.11 – 0.21. General waterquality parameters are as follow: temperature: 28 – 30 °C, pH: 6, brightness: 38 – 70.5 cm, DO:6.7 – 7.6 mg/L, CO2: 9.8 – 12.7 mg/L, Nitrate: 0.02 – 0.04 mg/L and phosphate: 0.09 – 0.018mg/L. Based on phytoplankton abundance, the Solok Pulau Lake can be categorized asoligotrophic lake.Keywords : Phytoplankton Diversity, Bacillariophyceae, Solok Pulau Lake

Abstract

Parit Belanda swamp is flood plane area located around the Parit BelandaRiver, Pekanbaru. This swamp is inhabited by various types of aquatic plants andthey almost cover the surface of the swamp. A study aims to understand the typesand density of the aquatic plant was conducted from November to December2015. Field sampling was done 2 times a month. The plants were then identifiedbased on Van Steenis (1981). Results shown that there were 6 species of aquaticplants present and they are belonged to 3 classes and 6 families. They arePaspalum commersoni, Eichhornia crassipes, Colocasia esculentum, Salvinianatans, Ipomoea aquatica and Pandanus tectorium. The most common plant isPaspalum commersoni (40.4-53.3 organisms/m2 , relative density 47.08-47.08 %)while the rarest was Colocasia esculentum (3.2-5.9 organisms/m2, relative density3.36-5.83 %). In general, the relative density of aquatic plants in the Parit BelandaSwamp can be categorized as rare to dense.Key words : Aquatic plants, Density,Parit Belanda swamp

Abstract

Tangun River is one of the Kampar Kanan River tributaries. During the rainy season, however, the water level of the Kampar River increase, flow to the Tangun River and enable fish to enter that river. As the information of fish present in that fish is rare, a study aims to inventarize and identify fish that inhabit that river was conducted in Februari-April 2016. Samplings were conducted weekly and the captured fishes were then identified based on Kottelat et al (1993) dan (2013). There were 707 fish sampled and they were belonged to 17 species (6 Ordos, 13 Families). The common fish in the river were Esomus metallicus, Pterygoplichthys pardalis, Poecilia reticula, and Trichogaster trichopterus, while the rare fishes were Trichopsis vittata, Ompok hypophthalmus and Helostoma temminckii.Keyword: Inventarisation , identification, Tangun River, Pekanbaru, Riau

Abstract

This research was held from 1 to 31 August 2015. The samples were collected from Pasir Panjang coast of Karimun Island of Riau Islans Province. The seaweed Eucheuma cottonii is one of the marine commodities that has high economic value and as a source of non-oil income. seaweed contained organic materials such as polysaccharides, hormones, vitamins, minerals and bioactive compounds. Escherichia coli can cause digestive tract disease such as cholera, typhoid, dysentery, diarrhea and worm diseases. The aim of this study was to analyze differences of antibacterial activity of E. cottonii seaweed extract on the growth of E. coli bacteria. Inhibitory ability seaweed extract that is classified by obtaining the average value in the range of 6-8 mm. Antibacterial activity of E. cottonii seaweed extract tends to be bacteriostatic with an average value of 7.08 diameter with the highest obstacle in the extract concentration of 100%. The results showed that the extract of seaweed E. cottonii has the ability to inhibit the activity of E. coli bacterial growth.

Abstract

This research was conducted in October 2015. The study aims to determine the oil content contained in the sediments, abundance of macrozoobenthos in the sediment, and oil content in the sediment relationship and abundance of macrozoobenthos in the Gulf of North West Frontier Kabung method used is survey method, in which the determination of the location established three research stations and each station consists of 6 sampling points. Sediment samples were inserted into the plastic and labeled for chemical laboratory analysis of the fishery. Makrozoobenthos samples given a 10% formalin solution and then brought to the laboratory. Oil content in the sediment at high tide and low tide in the waters of the Gulf Central Kabung ranging from 766.666 to 1166.667 ppm, with the highest oil content was found in station 1 (Port Pertamina) and the lowest at Station 2 (Human Settlements). Type of macrozoobenthos were found in the waters of the Gulf Central Kabung consists of four classes, gastropods, bivalve, crustacean and Polychaeta. Macrozoobenthos species that have a relatively high abundance values at each sampling point the waters of the Gulf Central Kabung namely Alvania lineata. Based on simple linear regression, correlation between oil content with the abundance of macrozoobenthos gained a strong enough relationship, indicated by the value of r = 0.644. Mathematical equation: -0,019x + 41.46 with a coefficient of determination (R2) = 0.414, and has a negative correlation means that the higher the oil content, the abundance of macrozoobenthos lower, though only the remaining 41.42% influenced by other environmental factors.   Keywords: Oil, Sediment, macrozoobenthos

Abstract

The study was conducted in October 2015 in Asahan waters NorthSumatera. The aim of this research is to know the fishing ground in Asahanwaters based on conditions of sea surface temperature and chlorophyll-aabundance by using Satellite Images Aqua Modis. Methods used in this researchis survey method and a visual analysis Aqua Satellite Images Modis. The resultsof the analysis by the sea surface temperatures in the Asahan waters tending tolow that is in the range highest was in June namely 32,42°C -32,7°C. From theobservation the average concentration chlorophyll-a Asahan waters 2014maximum in January with an average 4,246013 mg/m3, and the lowest in Julyreached 0.913913 mg/m3. The higher sea surface temperatures henceconcentration chlorophyll-a progressively lower. In the restive of fishing groundof Asahan waters performed on highest 30,15°C -30,38°C with the lowest in therange of SST 29,68°C-29,91°C and the highest of klorofil-a 2,70164-3,0763 mg/m3 with the lowest in the range of 1,57761-1,95228 mg /m3.Keywords: Fishing Ground, Sea Surface Temperature, Klorofil-a,Aqua Modis,Asahan
