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

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.

Abstract

Catfish is one of the fish that has a high economical value. Catfish is accepted by society easily because of its advantages. These advantages include fast growing, good adaptive behavior, good taste, high nutrient, and cheap price. One of the factors that determine the success of aquaculture is the availability of adequate food, both quantity and quality. There are several alternative feed ingredients that can be used in the preparation of feed. One of these feed ingredients is azolla flour made from Azolla sp. plant. Azolla sp. plant contains large amount of protein up to 28,12% of its dried weight. Selection of the base material feed using Azolla sp. based on the research results Handajani (2000) which declare that the protein content Azolla sp. which is quite high, namely 28.12% dry weight. The addition of Azolla sp. in catfish feed formulation is expected to improve retention of energy and lower feed conversion ratio. The purpose of this study was to determine the addition of Azolla sp. in feed formulations affect the retention of energy and feed conversion ratio catfish. This research was conducted in July-August in the Faculty of Fisheries and Marine University Airlangga. Research method used in the study was an experimental method with complete random planning. It included five treatments and four repetitions. Treatments that were used included azolla flour inclusion 0%, 5%, 10%, 15% and 20% at the formulated feed. Data analysis that was used included statistic and descriptive. The result of the research shows that energy retention among treatments does not have significant difference. On the other hand, the feed conversion ratio also does not have significant difference. It can be concluded that Azolla sp. inclusion in the catfish feed formulation affects nothing to energy retention and feed conversion ratio.  Keyword : Azolla sp., Clarias sp., Energy Retentiom, Feed Convertion Ratio
