Abstract

The research on Escherichia coli (E. coli) and bacterial pathogens within catfish culture in Buluh Cina Village has been done in August 2015. This study aimed to analyze the quality  of the river water, the abundance of E.coli in the water stream and pathogenic bacteria in catfish and to correlate the quality of the water with an abundance of E. coli and the prevalence of pathogenic bacteria. The location of the study is three observation stations with sampling conducted by three replications. The water quality parameters under investigation were temperature, brightness, pH, DO, Nitrate, Nitrite, Ammonia, Phosphate, TSS and BOD while the indicator for microbiological contamination  is done by testing the abundance  of E. coli in the river water as well as the pathogenic bacteria in catfish. The results  of water quality measurements and testing of E. coli indicate the water quality is still good  with the standard required under Regulation No 82/2001 except ammonia, phosphates, nitrites and E. coli. Ammonia has exceeded the threshold value with the  average  from 0.018 to 0.059 mg/L, the phosphate on the average value of 4,921 to 9,804 mg/L, nitrite  in the average value from 0.015 to 0.068 mg/L and the abundance of E. coli on the value of the average 4,200-5,500 cfu / 100 ml. While the results of testing on pathogenic bacteria found in catfish are Aeromonas sp, Pseudomonas sp, Pasteurella sp and  Edwardsiella sp. The highest prevalence of pathogenic bacteria obtained in Aeromonas sp is equal to 29.63%. In the statistical test toward  chemical parameters of water  measured affects  the abundance of E. coli by 94%. The most significant variable on the water quality parameters affecting the abundance of E. coli is the temperature, TSS, pH, and DO with a correlation coefficient lebih dari 0.5.

Abstract

This research was conducted in November 2015 until February 2016 located at Liung River waters Bantan District Bengkalis Riau Province with the aim to analyze the oil content in water and aquatic sediments, the structure of the plankton community and macrozoobenthos. The survey method was applied in this research with four research stations as sampling point. Samples were analyzed in the Laboratory of Ecology and Environmental Management of Water and Food Chemistry Laboratory of the Faculty of Fisheries and Marine Sciences of the Riau University. The results showed that the oil content in water ranged from 0.225 to 0.325 ppm and in sediments ranged from 447.67 to 582.33 ppm. The high oil in the sediment is possible because the oil accumulates in the sediments that are affected by the current state. The abundance of plankton ranged from 1200 to 4266.67 cells/L and found 18 genera with index of diversity index (H') 2.5022 to 2.9477, dominance index (C) 0.1481 to 0.2524 and index of uniformity (E) 0.7533 to 0.9299. Similarly, the abundance of macrozoobenthos ranged from 55 to 82.33 Ind/m2 and found 10 genera with diversity index (H') 0.9169 to 2.2489, dominance index (C) 0.2231 to 0.5565 and index of uniformity (E) 0.9169 to 1. The regression analysis between oil content in coloum water with plankton abundance shows negative correlation (Y = 5811.383 – 10167.685X; R2 = 0.353; r = 0.594) and oil content in sediment with macrozoobenthos abundance also show negative correlation (Y = 120.923 – 932.202X; R2 = 0.511; r = 0.715).
