Abstract

Fish meal prepared from salted by-catch contained a very high saltconsentration, therefore it must be reduced to prevent its effect to feedconsumption and growth of fed animals. This research was intended to evaluatethe effect of boiling time and water volume on salt reduction of fish meal preparedfrom salted by-catch. Salted by-catch comprised of various fish species, wasobtained from the trash fish supplier in Kampar. The fish was cleaned and boiledin boiling water with ratio of fish and bloiled water was 1: 2, 1: 3, 1: 4respectively for 15, 30 and 45 minutes. The fish was dried and grinded to fish2JOM: OKTOBER 2015meal. The effect of boiling was evaluated of salt concentration, proksimatecomposition, and NPN concentration. The results showed that the saltconcentration of by-catch reduced as the longer boiling time and the higherboiling water volume. Protein composition, moisture and fat also reduced, but ashand NPN were slightly increased as the longer the boiling time and the higherboiling boiling water volume. Boiling time of 30 minutes and ratio of fish toboiling water volume of 1:2 might be the choice as they could reduce saltconcentration and maintained protein concentration relatively. Salt, protein, fat,NPN, moisture, and ash concentration of the fish meal was 2,02%, 20,81%,2,73%, 0,27%, 10,85%, and 49,25% respectively.Key word: Long boiling, boiling water volume, salt trash fish, fish meal,salinity, proximate composition, levels of NPN

Abstract

Helostoma temmincki is a freshwater omnivorous fish and it can be found in theTapung River swamp and in the Sail River. The water quality in the Tapung River swampis relatively good condition, while the water quality in the Sail River is bad it is polluted.As the water quality in general affects the blood condition of the fish, it is predicted thatblood condition of H. temmincki from the Tapung River swamp and the Sail Riverdifferent. To understand blood condition of H. temmincki from both areas, this study hasbeen conducted from February to March 2015. There are 9 fishes from the Tapung Riverswamp and 9 fishes from the Sail River. The fish blood was taken and analyzed forerythrocytes and leukocytes content, hematocrite and leucocrite levels and types ofleukocytes present. Results shown that the erythrocytes of fish from the Tapung Riverswamp was 2,658,889 cells/mm3 and that of the Sail River was 2,318,889 cells/mm3. Thenumber of the leukocytes of the Tapung River swamp fish was 176,389 cells/mm3 and thatof the Sail River fish was 200,056 cells/mm3. There were 5 types of white blood cells inH.temmincki, namely lymphocytes, thrombocytes, monocytes, basophiles, and neutrophils.Based on data obtained it can be concluded that the blood condition of H. temmincki fromthe Tapung River swamp was better than that of the Sail River.Key words: Tapung River swamp, Sail River, Helostoma temmincki, blood

Abstract

This research was conducted in February 2015 located in the coastal area of Kuala Indragiri, Riau Province. This purpose of this study was to know the diversity macrozoobenthos and observe the relevance sediment content organic matter with the abundance of macrozoobenthos. The method used in the study was a survey method. Sampling macrozoobenthos was conducted by using 50 meters transect line, from the lowest tide limit to the highest tides and on each transect three plots with a size of 1 x 1 m2 was applied. The research recorded 13 spesies of macrozoobenthos consisting of 4 classes, namely class Gastropoda (Telescopium Telescopium, Eupleura caudata Chicoreus capucinus, Strombus sp, sp Cherithidea, Nerita sp, Babylonia spirata, Morulla striata), Bivalves (Anadara granosa, Placuna placenta), Crustaceans (Uca coartata, Sylla serrata), and Polychaetes (Eunice viridis). Diversity of macrozoobenthos was medium, nothing species dominates and uniformity was evenly. The average content of organic matter was 7.23%. Correlation of sediment organic matter with abundance macrozoobenthos was significant r = 0.907.Keywords: Diversity, Macrozoobenthos, Sediment Content Organic Matter, Indragiri Hilir.

Abstract

This study was conducted in January 2015 to determine the heavy metal concentration of lead (Pb) and copper (Cu) in seawater and sediment in the west coast of Karimun Besar Island of Riau Archipelago. Samples of sea water and sediment were analyzed for their metal concentrations in Marine Chemistry Laboratory Department of Marine Sciences University of Riau Pekanbaru by using AAS Perkin Elmer 3110. Metal concentrations in the sea water were highest in Station I (Pb 0.270 mg/L and Cu 0.140 mg/L), whilst concentrations in the sediment were found to be highest in stations III (Pb 8.055 μg/g, Cu 5.359 μg/g). Concentrations of Pb and Cu in the sediment in the study area was still below the Dutch quality standard for metals in sediments and the default value of the ERL and ERM. Based on I-geo calculations it was considered that the study area still has low impact on aquatic ecology.Key Words: heavy metal, seawater, sediment, Karimun, Lead, Copper

Abstract

This research was conducted from January to March 2015 by taking samples of seawater and sediment from the west coast of Karimun Besar Island of Riau Islands Province and analyzed their heavy metals concentrations. Analysis of samples was carried out in Marine Chemistry Laboratory, Faculty of Fisheries and Marine Sciences, University of Riau by using Atomic Absortion Spectrophotometer. The results showed that the highest concentrations of Cd (0.109 mg/L) and Zn (0.227 mg/L) in seawater were found in the area of the boat and harbour activities, whilst the highest concentration in the sediment samples were found for Cd in Pelawan Coast (3.664 μg/g) and Zn (6.552 μg/g) in the ferry port area. The highest organic matter in the sediment was found in the ferry port (3.82%) and the lowest was in the Pelawan Coast (0.65%). Zn concentrations in sediment were still below the range of the ERL but Cd concentration has already exeeded the ERL but still below the ERM value. Based on Potential Ecological Risk Index, Cd may cause possible negative impact on the aquatic ecology of the West Coast of Karimun Besar Island.Key Words: Heavy Metals, Water, Sediment, Karimun

Abstract

This research was conducted to test the antimicrobial activity of bacteriocin isolates of probiotic bacteria isolated from giant prawns (Macrobrachium rosenbergii). The method used was experiment method with tested the inhibition against pathogenic bacteria (Vibrio alginolyticus, Aeromonas hydrophila and Pseudomonas stutzeri). The results showed that bacteriocin capable of inhibiting the growth of pathogenic bacteria of P. stutzeri, A. hydrophila and V. alginolyticus. The best isolates obtained from results of this research was UG4 with clear zones ranging from 7.2 to 11.4 mm and the inhibition activity of 1476.53 mm²/mL after fragmentation with (NH4)2SO4 against pathogenic bacteria P. stutzeri was incubated at room temperature (37°C). This inhibition was caused by the presence of antimicrobial compounds that are produced by probiotic bacteria, namely bacteriocin. For isolates UG2 codes, the bacteria was resistant in which characterized by the formation of bluring zone around the paper disc.Key words: Antimicrobial activity, probiotics, bacteriocins, giant prawns

Abstract

The study was conducted in February-March 2015 on mangrove forest ecosystems in the Coastal Zone of Kuala Indragiri Riau Province. The aim of research was to analyze the content of carbon in mangrove forest ecosystems as well as the ability to store carbon in the forest area. The survey method was applied in this study and carbon analysis was carried out in the Marine Chemistry Laboratory of Faculty of Fisheries and Marine Science of University of Riau. The study showed that the potential mangrove biomass was directly proportional to mangrove carbon stocks. The average yield of biomass and carbon stocks of soil organic carbon reserves amounted to 258.03 tons/ha and 1476.40 tons/ha, while the average yield of total carbon stocks was 1734.43 tons/ha.Keyword: Mangrove, Carbon, Biomass, Organic Soil, Kuala Indragiri.
