Abstract

The study was conducted to evaluate consumer acceptance of seaweed ball fortified with catfish protein concentrate . About 5 kg seaweed was taken from a fish market in Pekanbaru. Three types of seaweed balls were prepared from seaweed flour which was fortificated respectively with 5%, 10%, and 15% catfish protein concentrate. The seaweed balls were evaluated for consumer acceptance and chemical composition. The results indicate that the seaweed balls added with 15% catfish protein concentrate was the most preferable by consumers. The seaweed ball contains water 58%, protein 12,85%, and crude fiber 5,23%.

Abstract

This research was carried out to evaluate the effect of ascorbic acid on quality changes of tilapia abon during room temperature storage. Tilapia weighing 400-600 g each was taken from a fish market in Pekanbaru. Three fish abons prepared from the fish meat were respectively added with ascorbic acid : 0% (A0), 2 g (A1) and 3 g (A2) of the fish weight. The fish abon were packed in HDPE plastic bag and kept at room temperature for 60 days. The quality changes were evaluated for sensory quality, moisture, fat, peroxide value and mould every 0, 30 and 60 days. The result indicated that the quality of A1 and A2 was more stable than that of A0. Both abons were still acceptable up to 60 day storage while A0 was rejected at 30 day storage. Peroxide value of the abon at initial to the end of storage was 1.68-10.62 meq/1000 g sample for A0, 0.78-7.96 meq/1000 g sample for A1 and 0.50-5.86 meq/1000 g sample for A2. Moisture at initial to the end of storage was 2.78-9.15% for A0, 2.96-6.12% for A1 and 3.08-7.97% for A2. Fat at initial to the end of storage was 24.19-3.89% for A0, 21.63-27.20% for A1 and 20.23-26.36% for A2.Keywords: Oreocromis niloticus, sorbic acid, tilapia abon, storage

Abstract

This research was conducted from May until Juny 2013 at LaboratoryAquaculture of Technology University of Riau. The purpose of this research wasto investigate growth of the African catfish with high stocking density in bioflocktechniques. This research using exsperimental method and Completely RandomDesign (RAL) with three treatments and three replications, there are P1: stockingdensity of African catfish 100 fish/m2, P2: stocking density of African catfish 200fish/m2, dan P3: stocking density of African catfish 300 fish/m2. The result showedthat African catfish with high density in bioflock techniques was not effectedsignificantly on absolute growth weight, absolute growth length, daily growth rateand survival rate. But the best treatments in this research was stocking density offish 200 fish/m2, with high growth weight rate 17,25 g, lenght growth rate 7,84cm, daily growth rate 6,65%, and survival rate 94,66%.Keyword : African catfish, High density, Bioflock technology

Abstract

The main purpose of this study was to reveal the depositional environmentand the movement of coastline. This study was conducted in January 2013 innorthern part of Rangsang Island, Meranti District. Sediment samples were takenfrom 11 station sand analyzed by using mechanical granular method. The methodof remote sensing linear regression was used to determine the movement ofcoastline. The result of study show that the surface bottom sediment ischaracterized by sand and mud fractions, and is dominated by bottom characterof sand. The study area was a transitional area where waves and currents werepredicted to change frequently through not too significant. The currents strengthtend to move with the fluctuations. The average change of the coastline during thepast 13 years (2000 to 2013) was 7,455 m/yr with the greatest changes occurredat station 7, i.e. Kedabu Rapat Village, with 8.54 m/yr. The speed movement ofcoastline was marked by the destruction of land cover in the north along the coastof the Rangsang Island as indicated by destruction of mangrove forests andvegetation coast, the sinking of jetty, roads and houses as well as the erosion.Kata kunci: movement of coastline, sediment coastal, Rangsang Island, abrat

Abstract

This research was conducted in April 2013 and was located at Riau marine waters. Samples were analyzed in the Biology Laboratory of Marine Science Department of Fisheries and Marine Science Faculty of Riau University. The aim of this study was to observe the phytoplankton communities. This research used survey method. The study found 31 species of phytoplankton, these were 19 species from Bacillariophyceae, 9 species from Dinophyceae, 2 species from Chlorophyceae and 1 species from Cyanophyceae. Phytoplankton was dominated by group of Bacillariophyceae (Diatoms) 61%. The other groups comprising of Dinophyceae 29%, Chlorophyceae (7%), and Cyanophyceae 3%. Phytoplankton abundance varied from 87-593 ind/L, the higest value in station 9 Zone III and the lowest value in station 11 zone III. Whereas the highest value of zone abundance was zone II 443 ind/L and the lowest was zone I 253 ind/L. Phytoplankton community was dominated by the group of diatoms, such as Nitzschia sigma, Thallasiothrix longissima, and Thallasiothrix delicatula.Keywords: Marine Phytoplankton, Bacillariophyceae, Marine of Riau1)

Abstract

The research was carried out in April 2013 to analyze the content of heavy metal Pb, Cu and Zn in soft tissues and shells of hard clam (Meretrix meretrix) from coastal waters of Batubara and to find out the correlation between size and content of heavy metals in both hard and soft tissues, as well as to determine the safe level for consumption of this organism. The results showed that the content of heavy metals Pb in the shells is higher than in soft tissues while Cu and Zn is higher in the soft tissues. The average heavy metals content in soft tissues were different with size, where Pb (1,83 μg/g) and Cu (4,25 μg/g) was found to be higher in larger size and Zn (23,44 μg/g) was found to be higher in smaller size. In the shells Pb was higher in smaller size (2,96 μg/g), Cu was higher in larger size (4,35 μg/g) and Zn was higher in larger size (23,44 μg/g).

This research was conducted in June-July 2013 in the village of Concong In Indragiri Hilir Riau Province. The method used in this research was a randomized block design (RAK) consisting of 5 treatments and 10 replications thus obtained 50 experimental units. This study aimed to determine the rate of growth of propagules R. mucronata good at various intensities shade. The results showed growth of propagules R. mucronata significant effect on height growth, diameter, survival percentage, number of leaves and total biomass. High growth in most large propagules present in 25% shade intensity is 0,23 cm. Greatest diameter growth found in 25% and 75% shade intensity is 0,006 cm. Highest percentage of life, of all the intensity of shade. Leaf shade intensity is highest at 100% ie 1.3. Propagules greatest total biomass present in 50% shade intensity is 1.3 grams.Keywords: Riau, R. mucronata, Growth, Shade intensity
