Abstract

The aim of this study was to know antibacterial potency of ethanolic extract of drumstick leaf against Aeromonas hydrophila in vitro. Total flavonoid, alkaloid, tannin and saponin of the ethanolic drumstick leaf extract were analyzed using spectrophotometry. Antibacterial activity test was carried out by disk diffusion and tube dilution method. Ethanolic extract of drumstick leaf contained flavonoids total as 71.9 mg quercetine equivalent/g, alkaloids total as 3 mg quinine equivalent/g, tannin as 24.7 mg tannic acid equivalent/g and saponin as 44.4 mg/g. The result of antibacterial test showed significant inhibition of Aeromonas hydrophila by drumstick leaf extract (P<0.05). The highest inhibition zone was produced by drumstick leaf extract with concentration of 100% which is 9.9± 0,162 mm. The minimum inhibition concentration (MIC) of drumstick leaf extract is 3.125%, while the minimum bactericidal concentration (MBC) is 6.25%. Based on this study, it can be concluded that drumstick leaf can be used as an alternative natural product of antibacterial agent which can be applied especially in aquaculture.

Abstract

One disease that often attacts fish is a group of parasites or parasitic diseases, parasites are not only dangerous because they are related to their activities, but also trigger the emergence of other pathogenic organisms and cause infections. Therefore, it is necessary to take fish quarantine measures to prevent the spread of diseases carried out by fish quarantine centers. This study was conducted to determine the type of parasite that infested fish samples and determine the prevalence and intensity of fish samples. A total of 48 sample fish consisting of freshwater and seawater fish were analyzed in the laboratory of Balai Karantina Ikan, Pengendalian Mutu dan Keamanan Hasil Perikanan Surabaya II during December - January 2019, either directly or directly (ectoparasites and endoparasites). Parasitic identification was carried out visually and microscopically with an approach based on identification books. The types of parasites that we found during the study consisted of Argulus sp, Trichodina sp, Anisakis sp., Gnathostoma spinigerum, and Gnathostoma spinigerum. The highest prevalence in Scomber Scombrus with Anisakis sp. Amounting  to 77.8%, mean while, the lowest prevalence and the intensity is found in Thunnus sp. The prevalence and intensity of parasites are influenced by water quality and pollution.

Abstract

Crab (Scylla serrata) is a commodity that has high prospects for cultivation. Cultivation in Indonesia has not been intensive and densely spread low due to the threat of crab deaths due to cannibalism. The purpose of this study was to determine the comparison of the growth of male and female crabs in the recirculation system to increase the productivity of mangrove crab. The research was conducted from November 2019 to June 2020 at the Aquaculture Laboratory, Faculty of Fisheries and Marine Sciences Satya Negara University of Indonesia and blood tests were conducted at the Center for Freshwater Aquaculture Fisheries- Bogor. The experiment used a Complete Randomized Design (CRD) consisting of three treatments and five replicate each. The treatments consisted of: A: male crab; B: female crab; C: Control. The number of seeds that used in this study were 5 for each treatment with five replications and density of 5 crab per maintenance container (gallon). The feed provided were fish feed selar Atule mate which was cut into small pieces. The selar fish came from Muara Angke, North Jakarta. Feeds were given with frequency 4 times a day. The results showed that the growth of male and female mangrove crab gave the best production performance in the treatment of female maintenance containers with survival rate of 53.33%, absolute growth rate of 3.76 g, and carapac width of 3.44 mm.Keywords: crab (Scylla serrata.), growth, recirculation system

Abstract

The study of biodiversity is important in looking at the current condition of an aquatic environment. The purpose of this study is to examine the biodiversity of the fauna in the Progo River in determining the level of fish diversity and the status of fish resources in the Progo river by using a Geographical Information System (GIS). The sampling method was carried out by purposive sampling consisting of 17 stations. The data taken includes coordinate points, the diversity index (H '), evenness index (E), dominance index (D), and relative abundance (Kr), as well as making a map of the distribution of progo river fish using Arcgis software version 10.5. The results showed that the diversity index value (H ') was moderate to high with a value range of 2.24 to 3.83, with a catch composition consisting of 23 species and 11 families. The evenness index value (E) of the progo river ranges from 0.71 to 1.21. Based on this value, the Progo River has an evenness value between species that is relatively even or the number of individuals of each species is relatively the same. Progo river dominance index value ranges from 0.002-0.008, that is, no fish species dominates. The highest relative abundance (Kr) was balar fish (Barbonymus balleroides) = 0.12%, melem fish (Osteochilus vittatus) = 0.11%, uceng fish (Nemacheilus fasciatus) 0.09%, tilapia fish (Oreochromis niloticus) 0 , 08%, while the lowest was kekel fish (Glyptothorax platypogon) and sepat fish (Trichopodus trichopterus) with a value of 0.01%. The results of the analysis of the distribution of fish in the Progo river show that the fish are widely distributed in the river area which has deep and calm water characteristics, this is indicated by the number of catches at each research station.Keywords: Biodiversity, Progo River, Geographical Information System (GIS)

Abstract

Parasite infections in aquaculture can trigger primary infections due to decreased fish immunity making it easier for other microorganisms, both bacteria and viruses, to enter the fish's body. This study aims to identify, calculate the prevalence and intensity of parasites that found in catfish ponds of the "Mino Ngremboko" fish farmers group in Grabag Village, Grabag District, Purworejo Regency. This study used the scraping method by reviewing the gills, mucus from the skin, fins and digestive tract onto a glass object which was then observed microscopically using a light microscope with a magnification of 10-40x. The parasites found were ectoparasites consisting of 6 species; Trichodina sp., Tetrahymena sp., Gyrodactylus sp., Epistylis sp., and Dactylogyrus sp. No parasites were found from the endoparasite and hematozoa groups. The highest prevalence was Dactylogyrus sp. with a prevalence rate of 54% and the lowest was Dinoflagella with a prevalence rate of 10%. The highest and lowest parasite intensities were Epistylis sp. (18,0 ind./infected fish) and Dactylogyrus sp. (2,8 ind./infected fish), respectively. It can be concluded that the level of parasitic infections in the fish farmer groups ponds was at the “common-usually” level based on William and Bunkley's prevalence criteria.Key words: Clarias sp., identification of Parasite, prevalence, intensity, Mino Ngremboko

Abstract

Harvesting microalgae is an important part in the culture system to produce higher crop biomass. Microalga Harvesting can be done by several techniques such as centrifugation, filtration, sedimentation, flocculation, ultrasonic vibration, and using filter. The technique currently used on an industrial scale is flocculation. This technique is used because it is more quickly and efficiently. Flocculants safe materials are polymers of polysaccharide seaweed. The study was conducted to determine the efficiency of the use of flocculants from alginate, carrageenan, so that the flocculation process microalgae Dunaliella salina. Flocculation process at the 50-minute show flocculation by material alginate by 30.52%, 22.85% by carrageenan, 11 % by Agar, plankton without flocculation make flocculates only amounted to 3.96%. Flocculation process at 240-minutes unchanged where carrageenan increased flocculation becomes 39.84%. Agar increased to 31, 48%. Plankton added flocculant alginate did not experience significant changes that just turned into 30.89%. The research results Show best flocculation activity is carrageenan where flocculation speed equal to alginate that has been frequently used as flocculants.Keyword : Dunaliella salina, flocculants, Carrageenan, Alginate, Agar

Abstract

Effect of chemical compounds in the wastes of essential oil distillation including lime leaves, lemongrass leaves, ylang-ylang flower, and coriander seed on the activity of Escherichia coli has been performed. In this research, observation was done by using microbial fuel cell (using E.coli) with two compartments were connected by nafion membrane and zinc plats were used as electrodes which were connected by copper wire and multimeter. Energy production from the cell was shown from the generated current due to the E.coli’s oxidation activity to the substrates (distillation wastes). Results from the research exhibited that chemical compounds in the lime leaves positively affected to the bacterial activity with the generated current present up to 20 µA. It is also observed that mass variation of the substrates significantly affected the current generation. Chemical compounds in the three other wastes were found to be not as effective as lime leaves because from the analysis of their methanol extracts by GC-MS indicated that these contained antibacterial compounds such as octadecanoic acid and rosifoliol. Conclusion from the research was not all of wastes from essential oil distillation have a potency to be used as substrates in the microbial fuel cell as some of these chemicals had an antibacterial property which negatively affected the E.coli bacterial activity in the cell. Keywords : microbial fuel cell, Escherichia coli, waste of essential oil distillation.
