Abstract

ABSTRACT             This research was conducted in April 2019 with the aim to determine the abundance of macrozoobentos, the content of total organic sediment material and the relationship of total sediment organic matter to the abudance of macrozoobentos inte mangrove area of Anak Setatah Village. The determination of the sampling is purposive sampling. The results showed the highest value of macrozoobentos is 4,89 ind/m2. The highest average value of organic matter content in sediments is 13,71%. Simple linear regression analysis between abundance of macrozoobentos and total organic matter content of the sediment obtained by the equation y = 2,5462 + 0,1566x (r = 0,729).Key word : Mangrove, Macrozoobentos, Abundance, Organic of Sediment, Anak

Abstract

                                                ABSTRACT Heterotrophic bacteria is a group of organism that play important role in biogeochemical processes in aquatic ecosystem.The bacteria are able to decompose and remineralize organic materials into a simple inorganic components which is turn to nutrients for phytoplankton, perifiton, and other aquatic microflora. This Study was conducted from September to October 2018. The purpose of this study wos to obtain bacterial isolates that can be used as an antibacterial against pathogenic bacteria and to identify bacteria found in River estuary Masjid Dumai of Riau Province. Based DNA character the result found10 bacterial isolates. The bacterial (1A, 1B, 1C, 1D, 1E, 1F,1J, 2C, 2D, and 2G). These bacteria were able to inhibit the pathogenic growth. DNA identification using PCR and 16S rRN sequence technique resulting found6 types of bacteria, namely Bacillus cereus strain ATCC 14579, B. anthracis strain ATCC 14578 16S,B. methylotrophicus strain CBMB205 16S, B. thuringensis strain YBT-1518, B. pseudomycoides strainNBRC, and B. anthracis strain C10.Keywords: Heterotrophic Bacteria, Antibacteria, 16S rRNA Sequence, Pathogens.

Abstract

ABSTRACT  granosa.This research was conducted from January to April 2019 by taking samples of blood cockles from the waters of the Asahan river, Tanjungbalai city, North Sumatra Province. The purpuse of this research were to know the metal concentrations of Pb, Cu and Zn in different station and different sizes of blood cockle’s shell (Anadara granosa), as well as to find out the level of metal pollution based on MPI (Metal Pollution Index). Analysis of metal concentrations of heavy metal was done by following procedurs outline by Yap et al., (2003). The results showed that the highest Pb metal concentration in meat of small blood clams was found at station 3 namely, 0.7100 μg / g and the low concentration was 0.4716 μg / g at Station 1. While the highest concentration at medium size was found at Station 2 namely , 1.3683 μg / g and low concentration was 0.8000 μg / g at Station 1. The highest Pb concentration at large size was found at Station 3 ie, 2,2200 μg / g and the lowest concentration was 1,2266 μg / g at Station 1. The calculated MPI value for the Asahan estuary research from this study was 3,7260  which was considered quite low compared to other regions. Keywords: Heavy Metal, Pollution, North Sumatra, Industry, Anadara

Abstract

ABSTRACT Mikroalga is a large group of aquatic organisms that is very diverse, does not have a complex cell structure, with a diameter between 1-50 µm and can be found in various environments such as freshwater, brackish and sea water or damp places other mikroalga which formed the basis of the food chain. This research was carried out from December-January 2018 in the laboratory of Marine Biotechnology and Marine Chemistry Laboratory, Faculty of Fisheries and Marine Science University of Riau. The aims is to find out the influence of biomass and growth rate differences salinity (ppt, 15 20 25 ppt, ppt and 30 ppt) against a platensis cultivation mikroalga s. on the scale of the spring pool. The method used is the method of experiment using Random Design. The results showed that the growth of biomass at all salinity treatments experienced the highest increase on day 10 observations. The number of maximum biomass growth was 0.078 g/L salinity treatment at 25 ppt, and growth the lowest biomass is 0.019 g/L on the treatment of 30 ppt. Statistical analysis (ANOVA) showed that the difference in salinity towards the growth of biomass mikroalga s. platensis gained real influence there, where values (P < 0.005). Linear regression analysis shows that the influence of salinity towards the growth of the biomass is weak, with the value of the coefficient of determination R2 = 0.012 and coefficient of correlation r = 0.109.

Abstract

ABSTRACT This study was aimed to determine of sensory evaluation for consumer acceptance on meatball made from a mixture of beef and freshwater mussel meat (Plisbryoconcha exilis). The method used was an experimental method with the addition mixed of beef and freshwater mussel meat into meatball consisting of 5 levels treatment: B0 (0%:100%), B1 (15%:85%), B2 (30%:70%), B3 (45%:55%), and B4 (100%:0%). A Completely Randomized Design (CRD) as an experimental design with 3 replicated. The parameter tested was sensory evaluation (consumer acceptance) for appearance, aroma, taste, and texture with 80 untrained panelists, using a 9 point hedonic scale.  The results showed that the meatball made from mixture of beef and freshwater mussel meat 45%: 55% (B3 treatment) was the best treatment with overall likability 35% panelists (28 panelists), for overall acceptability was 100%, wherein appearance 7.98 (brilliant and intact meatball), aroma 7.75 (distinctive aroma of mixed beef and freshwater mussel meat), taste 8.32 (very tasteful), texture 7.61 (very thick and dense texture). Statistical analysis of meatball made form a mixture of beef and freshwater mussel meat was significantly different among treatment with 95% of confidence level.Keywords: Meatball, beef, freshwater mussel meat,  consumer acceptance

Abstract

ABSTRACTThis study was aimed to determine the effect of the use of garlic (Allium sativum) on organoleptic and microbiological quality in dumbo catfish (Clarias gariepinus) during chilled storage. The treatment in this study was the concentration of garlic at a level of 0, 10, 15 and 20% with retention period of 0, 3, 6, 9 days. The test parameters performed included organoleptic, TPC, and Escherichia coli tests with non-factorial completely randomized design (CRD). The results showed that the use of garlic had significantly affected the characteristic of organoleptic quality (eyes, gills, texture and odor) and microbiological in catfish during cold storage. The use of 20% garlic  preserved the organoleptic quality of the eyes, texture, and odor for 6 days of storage. Meanwhile, the use of 20% garlic  reduced the number of microbes for 9 days of storage. Key words:Dumbo catfish, garlic, organoleptic quality, TPC.

Abstract

AbstractThis study was aimed to determine the organoleptic quality and pH of fresh baung (Mystus nemurus) soaked with chitosan solution with different concentrations. This research used the experimental method, by immersing the fish with chitosan solution with a concentration of 0% (without chitosan), 1, 2, and 3% and soaking time 0, 4, 8 and 12, for 16 hours. The analysis parameters were consisted of organoleptics including eye appearance, gills, mucus, meat (color and appearance), odor, texture, and pH test. The results were showed that immersion of baung in high concentration of chitosan can maintain freshness of baung fish. Soaking fish in 3% chitosan solution is able to maintain freshness with freshness for 12 hours aimed at the value of the eye value of 6.79 (sunken eyes, pupils turn white, cloudy corneas); gills with a value of 7.05 (pale red color, without mucus); odor 6.87 (Neutral). Immersion in chitosan solution for 16 hours produced atexture of baung fish 7.13 (rather soft, less elastic when pressed with a finger, difficult to tear meat from the spine); meat with a value of 7.12 (less brilliant, specific type, no milking along the spine, abdominal wall of whole meat);mucus with a value of 7.05 (The mucus layer starts to become slightly cloudy, the color is rather white, less transparent); and pH 6. The best treatment for this is immersion of baung fish with a concentration of chitosan 3%. Keywords: eye,freshness, solution concentration, texture,
