Abstract

The aim of this research was to find out the relationship between metals Pb, Cu, Zn concentration in sea water and in snail C. montagnei, to determine the pollution level of Desa Gemuruh coastal waters of Kundur Island, as well as to evaluate the safety level of the snail for human consumption. The research was conducted in February – March 2017 by collecting samples from three different stations from Desa Gemuruh coastal waters. Metal concentration analysis was done in Marine Chemistry Laboratory, Faculty of Fisheries and Marine Sciences University of Riau. The results showed that the average Pb, Cu, Zn concentrations in sea waters were 0,0408 mg/L; 0,0438 mg/L; and 0,1424 mg/L, while in snails were 1,0315 μg/g ; 0,9261 μg/g ; 54,1507 μg/g respectively for Pb, Cu, and Zn. The linear regression showed that the raising of Pb and Zn concentration in sea waters, were followed by increasing metal concentrations in snails, but Cu concentration in sea waters were not followed by its increasing concentrations in snails. The larger the body size of the snail the higher metals were accumulated by the snail. This study also showed that MPI values obtain from Desa Gemuruh coastal waters of Kundur Island 3,7260 were classified as lower than other research locations. Snails from this coastal waters are still considered to be safe to be consumed by human with safety level were 6,7864 Kg per week for Pb, 1079,7840 Kg per week for Cu, and 36,1953 Kg per week for Zn.Keywords: Heavy metals, marine pollution, Cerithidea montagnei, Kundur Island

Abstract

ABSTRACT                Heterotrophic bacteria are decomposing bacteria that have an important role in maintaining the continuity of the life cycle of biota in the sea and as a standard of fertility in the waters. Heterotrophic bacteria obtain sources of food, oxygen and energy derived from the results of the decomposition process of the rest of other organisms, waste, or substances contained in the bodies of other organisms. This study aims to determine the effect of adding different concentration and duration of surf detergent to the growth of heterotrophic bacteria in sea water. This research was conducted from April to May 2018 using the experimental method. The results showed that the bacterial population in each treatment decreased with increasing concentration of detergent. The results showed that the highest number of heterotrophic bacteria was found at a concentration of 0.60% at station 1 exposure on the 10th day at 6.60 x 107 (CFU / ml) and 0.90% at the station on the 10th day of the day exposure the 10th was 6.72 x 107 (CFU / ml) and the lowest was found at a concentration of 0.90% on day 5 exposure at station 1 at 3.83 x 107 (CFU / ml). The value of the correlation coefficient (r) obtained is 0.177. Significant treatment of detergent concentration is different, which is equal to 0.00 <(0.550) and duration of exposure which is equal to 0.00 <α (0.45). Based on the results of this study, there is a negative effect of the addition of surf detergent with different concentration and duration of exposure to the growth of heterotrophic bacteria in seawater. Keywords: heterotrophic bacteria, Surf detergent.

Abstract

Tiger shrimp is one of the most popular fishery products in the world. H. scabra has been shown to be a potential antibacterial agent. Potential antibacterial extract from H. scabra can be derived from the presence of antibacterial agents i.e steroids, saponins and triterpenoids. Bacteria V. harveyi is one of pathogenic bacteria which according to some research can cause disease in shrimp cultivation. Diseases caused by vibrio bacteria are usually called vibriosis. The purpose of this research is to know the effect of antibacterial activity of sea cucumber extract (H. scabra) on the growth of V.harveyi bacteria on tiger shrimp (P. monodon), to know the character and structure of bacteria which is inhibited by sea cucumber extract (H. scabra). This research was conducted in August 2016 in Marine Microbiology Laboratorium of Riau University. Based on the results of research that sea cucumber extract has the ability to inhibit the activity of V. harveyi bacteria. The mean value of the inlet zone is 4.06 - 6.26 mm.Keywords: Sea cucumber, Antibacterial, V. harveyi

Abstract

This research was conducted in March 2014 in the coastal waters of the Village of Kuala Enok of Indragiri Hilir Regency in Riau Province. The purpose of this study was to determine the level of bacterial contamination of E. coli as an indicator of pollution on “tembakul” (P. schlosseri) fish in the coastal waters of Kuala Enok. Tembakul fish sampling conducted at three observation station, station I is located in the territorial waters adjacent to residential, station II is located in the creek waters, and station III is located in the open sea waters. Samples of “tembakul” fish were analyzed by using the MPN method three series tube at the Laboratory of Microbiology and Biotechnology of Fisheries and Marine Sciences Faculty of University of Riau. The yield on the analysis of the sample gills, digestive tract and fish meat tembakul showed that at the settlement waters and the creek waters the number of bacteria was 1,100 MPN/g but had differences on the meat at the open waters with an average of 747.67 MPN/g. The results showed that the innoculation of bacteria growing at the time of isolation was from the coliform group. Total coliform values ​​at each point of observation station was above the food quality and safety standards required by BSNI 7388: 2009 and BPOM (Agency for Food and Drug Administration) of the maximum contaminant limits in food is 10 MPN/g in fresh meat.
