Abstract

ABSTRACTBlood cockle interact with physical and chemical oceanography factors caused by the tide intensely, so it’s not posible to blood coockle to free from heavy metal pollution. As a organisms, blood cockle are relatively sedentary and filter feeder, so that the presence of pollutants in the marine waters will be absorbed by the biota. Research on the absorption of zinc (Zn) with different salinity level and shell size was conducted in December 2017, it aims to determine the ability of zinc (Zn) absorption in blood cockle based on salinity level and shell size differences. The method used is experimental method using Factorial Randomized Block Design which is designed from 2 factors namely salinity and shell size. The absorption of Zn by blood cockles were higher at 20‰ compared to 25‰ as well as the uptake by 3 cm shells length of the cockles were higher than that by the cockles with 4,5 cm length. Based on the results of this study it can be concluded that the absorption of Zn in blood cockles in influenced by the difference of salinity and shell sizes.Key Words: Blood cockles, Salinity, Size.

Abstract

 Abstract    This research was aimed to determine the effect of fortification ofcatfish (Pangasiushypopthalmus) bone mealon baked browniesfor consumer acceptance with different concentrations. The research was conducted in two stages: 1) the production of catfish bone meal, 2) the production of baked brownies with addition of catfish bone meal. The method used in this research was an experimental method, using a Completely Randomized Design (CRD) non factorial. The results showed that the baked brownies which fortified 20 g ofcatfish bone meal (K3) was the best treatment based on aroma (7.45), moisture content (32.34%), protein content (4.73%),and calcium content (0.54%).Meanwhile for taste and appearance that the baked brownies which fortified 10 g catfish bone meal (K1) was most preferred with value of taste 7.24 and appearance 7.15, for texture and ash content that the baked brownies which fortified 15 g (K2)catfish bone meal was the best treatment with value 6.80 and 4.43%, respectively. Keywords: Consumer acceptance, baked brownies, catfish bone meal, Pangasiushypopthalmus

Abstract

ABSTRACT    This research was conducted on November 7thto December 11th2017 in the laboratory of Aquaculture Technology, Marine and Fisheries Faculty, University of Riau, Pekanbaru. The main purpose of this study was to determine the best stocking density to increase the growth and survival rate of catfishby using aquaenzymsboster probiotics on feed. The method was an experimental method of completely randomized design (CRD) with one factor, four treatments and three replications. The treatments in this study were P1 (35 fish/72 liters), P2 (50 fish/72 liters), P3 (65 fish/72 liters), and P4 (80 fish/72 liters). The respecti vely rearing tanks were 12 unitsof aquarium by 60 cm x 40 cm x 40 cm and filled of 72 liters of water. Feed was given three times a day with 35% of protein dose. The result of the observation showed that the stocking density 50 fish/72 literswas the best stocking density in this study which providedthe absolute growth weights was 16.16 g, specific growth rate was 6.09%, absolute growth length was 8.92 cm, and survival rate was 89.33%. The water quality parameters were in thetolerance range of catfish where the temperature was 26-28 0C, pH was 5-6, DO (Dissolved Oxygen) was 4.0-5.0 mg/L and ammonia was 0.022-0.085 mg/L. Keyword: Probiotics, Stocking density, Clarias gariepinus, Growth

ABSTRACT The purpose of this research was to determine the effect of addition of beetroot flour (Beta vulgaris L) on catfish (Pangasius sp) sausage toward consumer acceptance as measured by organoleptic parameter. The design used was Completely Randomized Design (CRD) non factorial. The treatment was by mixing the beetroot flour with different amount consisting of 4 levels i.e. S0 (without beetroot flour), S1 (5% of beetroot flour), S2 (10% of beetroot flour), and S3 (15% of beetroot flour). The best treatment seen from the organoleptic test was on the S1 treatment with the number of consumers who liked appearance of 96.25%, 95% flavor, 90% odor, and 85% texture. The resulting characteristics were reddish, tasteful, not too fishy, and compact texture with water content 67.44%, protein content 14.17%, fat content 9.37%, and ash content 1.71%, TPC 3.5x102 cfu/g, Escherichia-coli <3 MPN/g, Salmonella sp (Negative), and Staphylococcus aureus 0.8x102 cfu/g. Keywords: Sausage, Catfish, Beetroot, Consumer acceptance

Abstract

ABSTRACT Oil pollution in Bengkalis waters usually comes from land, marine transportation, defection port activities and oil industry. Oil pollution can be trapped in sediment because it can not be dissolved and difficult to degrade, one way to overcome pollution is by bioremediation. The purpose of this research was to isolate bacteria from sediment Sungai Pakning waters, to examine the ability of isolates in degrading crude oil and to identify the bacterial isolates genetically based on sequence 16S rRNA. The research was conducted from March to May 2018. Bacterial isolation was conducted in Laboratory of Marine Microbiology and the oil degradation analysis was conducted in Laboratory of Chemical Oceanography, Faculty of Fishery and Marine Science, University of Riau. This research used survey and experiment method, survey method to measuring of water quality, removal of sample and isolated of bacteria, experiment method to examine the ability of isolates in degrading crude oil. The result showed that eight isolates (7D15, 7D35, 7D23, 14D15, 14D34, 21D13, 21D23, 21D35) were able to degrade crude oil at 1-3% concentrations. The highest degradation at 1% concentration was indicated by 21D35 isolate, at 2%  concentration is indicated by  21D13 isolate, and at 3% concentration is indicated by 7D23 isolate. To molecular identification results by the 16S rRNA sequence take of three isolates have the highest degradation ability. 21D13 isolate was similar to Achromobacter pulmonis, 21D35 isolate was similar to Achromobacter sp., and 7D23 isolate was similar to Vibrio sp. Keyword : Pakning River, Oil Degradation Bacteria, 16 rRNA, Achromobacter, Vibrio

Abstract

ABSTRACTSeaweed community is ecologically refuge, foraging and orphanage for marine life, including macro epizoobenthos. The existence of a food source will affect the density of macro epizoobenthos in the aquatic ecosystem and important its influence on the structure of the food chain in the community of seaweed. This study was conducted in March 2018-April 2018 in Nirwana Beach of Padang City West Sumatra. The aims of research to find out : the density of each type of seaweed, the abundance of a macro epizoobenthos that lives on seaweed community and the relationship between the density of seaweed with a abundance of macro epizoobenthos. Sampling and measurement of water quality was done by using quadratic transect at 3 stations. The results of the study showed that the highest seaweed density has a value 451.4 tegakan/m2 and thehighest macro epizoobenthos abundance has a value 244 ind/m2in the area of seaweed that minimal activity and the lowestseaweedabundance has a value 169 tegakan/m2 and the lowestmacro epizoobenthos abundance has a value 27 ind/m2 in the area of seaweed around the population and settlement activities. The relationship of the density of seaweeds with the macro epizoobenthosdensity very strong i.e. y = 6.371 –0.553x; R² = 0.678; r = 0.82.Keywords: Seaweed Density, Macro Epizobenthos, Abundance, Nirwana Beach
