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

ABSTRACT This research was conducted from April - July 2018 at the Laboratory of Organic Chemistry and Natural Materials Synthesis Research, Faculty of Mathematics and Natural Sciences and Marine Microbiology Laboratory in the Department of Marine Sciences, Faculty of Fisheries and Marine Sciences, University of Riau. The purpose of this research is to know the ability of secondary metabolites to inhibit heterotrophic bacteria in inhibiting the activity of pathogenic bacteria (Vibrioalginolyticus, Aeromonas hydrophila and Pseudomonas aeruginosa). The research method used is the experimental method. 10 isolates of heterotrophic bacteria were obtained from a collection of Marine Microbiology, Faculty of Fisheries and Marine laboratories which were able to produce secondary metabolites. Each bacterial isolate was tested on pathogenic bacteria, namely Aeromonashydrophila (P), Pseudomonas aeruginosa (Q), Vibrio alginolyticus (R) using paper discs and each isolate was carried out 3 repetitions, so that 90 experiments were obtained. Test results of secondary metabolites of 10 heterotrophic bacterial isolates have the ability to inhibit the growth of pathogenic bacteria. The best isolate is J isolates with clear zones formed wider than the other test bacteria which is 12,35 mm and the activity of the bacteria was 1877,78 mm2 / ml. This inhibitory power is caused by the presence of compounds that are anti-microbial namely secondary metabolites. Isolates A, D, F, G, H are resistant to pathogenic bacteria Aeromonas hydrophilla, isolates D, E, G, J are resistant to pathogenic bacteria Pseudomonas aeruginosa. This is indicated by the presence of a cloudy zone around the disc paper that is formed during the inhibitory test Keyword : Secondary Metabolites, Heterotrophic Bacteria, Inhibitory Power
