Abstract

AbstractMedicinal plants proven to effectively cope with bacterial diseases one of which is the plant meniran (Phyllanthus niruri). Phyllanthus niruri can act as an antibacterial because it has an antibacterial ingredient content of flavonoids, alkaloids, phenols, and tannins. This shows that plants can be used as an antibacterial Phyllanthus niruri of E.tarda. The purpose of this study was to determine the ability of the antibacterial of Phyllanthus niruri extracts and to find out the best concentration of Phyllanthus niruri extracts as antibacterial E.tarda according in vitro. The experiment was conducted in January 2011, housed at the Laboratory of Bacteriology Juanda Fish Quarantine Center and Laboratory of Organic Chemistry and Technology Faculty of Airlangga University Saints. This research method is done by the Minimum Inhibitor Concentration (MIC) and Minimum Bacterial Concentration (MBC) with 12 treatment. The results showed that the best concentration for the treatment of the concentration of 0.0313 g / ml as indicated with no growth of bacteria and is the lowest concentration of the dilution. 
Sargassum Sp. Sebagai Biokontrol Terhadap Kandungan Logam Berat Timbal (Pb) Yang Terserap Oleh Kerang Darah (Anadara granosa) [Sargassum Sp.

Abstract

Abstract Shell is aquatic organism class of Molluscs as non selective filter feeder and also as seafood main menu. In other side many food poisoning case was found as result consuming of Shell. Timbale (Pb) is one of very dangerous heavy metal and able to caused of poisoning in organism. According to PP RI Number 82/2001 Pb concentration that was suitable with maximum limit of aquatic quality is 0,03 ppm. Sargassum sp. also was knowned have been absorbing ability for heavy metal like Pb that spread in aquatic. Hopeable with a Sargassum sp. as biocontroll model on timbale heavy metal contens is able to prevent food poisoning causing contaminated shell consumtion. This research was done in Fisheries Laboratorium Fisheries and Marine Faculty Airlangga University on 15th – 11th 2010. The research method is experiment with design of experiment that used is Completely Randomized Design Factorial with three replicates (I, II and III) and consist of two factors, that is Pb(NO3)2 in concentration 0.015 ppm, 0.03 ppm and 0.06 ppm, Sargassum sp. in weight 100 g, 200 g and 400 g. Data analysis using Analysis of Variance (ANOVA), if there are any different it could be continued with Honestly Significant Difference (HSD) Test to known interaction between treatments. Result of the research indicates that Pb dose is significantly (p<0.05) to Pb contens number that absorp by Sargassum sp. among research. It's supported by HSD test indicates that highest result is A3 (Pb(NO3)2 0,06 ppm) that significantly with A2 (Pb(NO3)2 0,03 ppm) and A1 (Pb(NO3)2 0,015 ppm). Sargassum sp. is also be able to used as biocontroll to timbale heavy metal contens that absorbed by shell, because in low and highest dose Sargassum sp. absorption capacity to the timbale always bigger than shell absorption capacity . In other side, there are no interaction between timbale dose and weight of Sargassum sp. to timbale contens that absorbed by shell.

Abstract

Abstract Daphnia magna is one of the natural food which is used widely in fish hatchery. Generally, Daphnia magna is used widely in larval rearing of fish that are traded in the form of resting eggs called ephipia. Ephipia production can be performed with Daphnia magna culture in conditions that are not optimal, one of which is pollution. If the conditions are not optimal then the parthenogenesis Daphnia magna would produced a male individual. The presence of Daphnia magna males will initiate sexual reproduction, where Daphnia magna males will perform on the female and copulation produce ephipia. Ephipia production is influenced by the efficiency of matting, reproduction ephipia will improve if a high mating eficiency of Daphnia magna. Mating eficiency describes the number of females that successflly fertilized by the male.The purpose of this study is to determine the reproductive capacity of Daphnia magna male's induction of heavy metals (Cd, Pb) and the Pesticide Diazinon on mating efficiency and quality ephipia produced. The research method used is an experimental method by using completely randomized design with 4 treatments and 5 replications so that was followed by Duncan Multiple Range Test. This study uses the ratio of male to female sex 1:30 for each treatment. The treatments in this study consist of control males mated with females, male induced lead (Pb) were mated with female, males induced cadmium (Cd) were mated with females, the male mated with the induction of pesticide Diazinon female. Results showed that treatments using natural male produced an average value of mates which were the highest efficiency and quality ephipia optimal, with precentage of 88,66 and 88,71. So that in order to produce ephipia in large quantities and quality needed natural male culture can be done in the unpolluted waters.
