    ANALISIS BAKTERI Clostridium perfringens PADA SEDIMEN DI PERAIRAN BENGKALIS PROVINSI RIAU
    (2013-01-07) Daulay, Haris
    The research was conducted in April 2012 in water of Bengkalis, Riau Province. This research aims to analyze of Clostridium perfringens on sediments of water in The Bengkalis coastal, Riau Provinces. Sediments of water were collected from Bengkalis coastal and then analyzed bacteriologically in The Marine Microbiology Laboratory of Marine Center. The data obtained by observation, measurement and sampling in the field, followed by the identification C. perfringens. The method used in this research is descriptive method. The C. perfringens counts varied according to types of sediments and location sampling. The inoculation thecnique is surface plate method on TSC Agar. The species identification included morphological, observation, fisical and biochemical test. The distribution of C. perfringens is connected of with coastal oceanography condition. The counts ranged from 3,9 x 104 - 6,1 x 104 cell/grams in sediments of water. The highest C. perfringens counts was found on water of Damon, Rimba Sekampung and Kelapa Pati Villages.

    ANALISIS BAKTERI Clostridium perfringens PERAIRAN SELAT BARU KECAMATAN BANTAN KABUPATEN BENGKALIS PROVINSI RIAU
    (2013-02-01) Siahaan, Deasy Melina
    Analysis of Clostridium perfringens in Selat Baru held in May 2012 and analyzes were conducted at the Marine Microbiology Laboratory of Marine Science, Faculty of Fisheries and Marine Science, Riau University. The results showed that the amount of bacteria ranged from 3,0 x 103 to 1,1 x 107 cfu/ml. Given that the trend of the number of bacterial colonies on the surface of the waters of the most abundant in station 3. Rod-shaped cells or chains and gram-positive bacteria with negative test motility, positive catalase, positive H2S test and positive methyl red test. While the results of water parameters were 31oC temperature, depth 2.7 m, pH 6, salinity 25.66 ‰, brightness of 69.33 cm and flow velocity 0.11 m/sec.
