    Opis:
    This study aims to determine the best density of Bacillus sp. which is given through feed to increase the body resistance of carp that is infected by pathogenic bacteria, Aeromonas hydrophila. The research was conducted at the Aquaculture Laboratory and Laboratory of Microbiology and Biotechnology at FPIK UNPAD. This study used an experimental method with a completely randomized design consisting of 4 treatments and 3 replications, namely treatment A (control), treatment B (Bacillus sp. 106 cfu/mL feed), treatment C (Bacillus sp. 108 cfu/mL feed) and treatment D (Bacillus sp. 1010 cfu/mL feed) for two weeks later in Aeromonas hydrophila infection with an intramuscular density of 108 cfu/mL for seven days. Observation parameters were clinical symptoms, fish response to feed, fish response to shock and survival. The results of this study showed that treatment C (Bacillus sp. 108 cfu/mL feed) resulted in 89% survival and reduced clinical symptoms.

    Opis:
    This study aims to examine the growth characteristics of B. cereus and B. zhangzhouensis and to see their potential in preventing the growth of Aeromonas hydrophila in vitro. This research was conducted in June 2020 - May 2021 at the Laboratory of Microbiology and Biotechnology, Faculty of Fisheries and Marine Sciences, Padjadjaran University. The method used is the exploratory method and the data obtained were analyzed descriptively. The growth curve was performed using the turbidimetric method. The inhibition test used the disc diffusion method with 5 treatments, chloramphenicol antibiotics (4000 ppm), distilled water, bacterial culture, 100% supernatant and 50% supernatant. The curve results showed that the growth of B. cereus and B. zhangzhouensis was slow. The stationary phase of B. cereus occurred at 40-72 hours, while in B. zhangzhouensis the stationary phase occurred at 48-72 hours. The results of the inhibition test showed that the antimicrobial activity of B. cereus and B. zhangzhouensis was weak with a value range of 0.71 - 1.6mm, besides that the results of the inhibition zone produced by these two bacteria have different inhibitory abilities in each treatment.

    Opis:
    This research was conducted to assess the antibacterial potential of Bacillus flexus and Bacillus subtilis against Aeromonas hydrophila. Bacterial samples came from the stock of the FPIK Unpad Biotechnology Laboratory. This research was conducted in July 2020 - May 2021 in Laboratorium Biotechnology FPIK Padjadjaran University. This research was conducted using qualitative and quantitative descriptive analysis. Bacteria were collected using the purposive sampling method, Observation of the growth curve using the turbidimetric method, and the disc diffusion method for the inhibition zone test with bacterial supernatant treatment with a concentration of 50%, a concentration of 100%, bacterial culture, chloramphenicol antibiotics with a concentration of 4000 ppm as a positive control. The results showed that B. flexus bacteria experienced an exponential phase at 6 to 12 hours, after which it entered a stationary phase at 14 to 72 hours. B. subtilis bacteria experienced an exponential phase at 20 hours. Until 40 hours, then experiencing a stationary phase at 42 hours to 72 hours, and the growth of A. hydrophila bacteria experiences an exponential phase at 6 hours to 28 hours, the stationary phase at 30 to 28 hours 72. Based on the results of the inhibition zone test, it showed the formation of the inhibition zone only in the positive control treatment, while the supernatant and bacterial cultures of B. flexus and B. subtilis didn’t form an inhibition zone.

    Opis:
    This study aims to see the condition of hematocrit levels and differential leukosit after immersion in LAB isolated and after in vivo, using Aeromonas hydrophila bacterium. LAB isolated were obtained from the organs of the common carp intestine. The study used a Completely Randomized Design (RAL) consisting of four treatments and three replications. The treatment used was immersion of test fish for 24 hours in several isolates of LAB with a density of 108, namely A: without LAB isolate (control), B: isolate CcB7, C: isolate CcB8, D: isolate CcB15. Immersion was done three times, with a frequency of seven days. Parameters observed included hematocrit levels, leukocyte differentiation and survival rate. The results showed that immersion in LAB isolate CcB15 will enhance the differential leukocytes and hematocrit levels that serve as indicators of carp body resistance, which is shown by high levels of white and red blood cells.
