Abstract

ABSTRACTAvicennia marina leaf extract is known to suppress the activity of Vibrio spp. using solvent klorform and methanol. Therefore, the authors conducted a further study using different solvents. This research interest determine the ability of extracts of A. marina in suppressing the activity of Vibrio spp. isolated from mud crab (Scylla serrata). A. Marina leaf take in Pantai Amal Lama, The process of extraction, isolation and testing of clear zone performed at the Laboratory of the Faculty of Fisheries and Marine Sciences, University of Borneo Tarakan. Stages of research are: manufacture A. marina leaf extract, isolation, culture of Vibrio spp., and data analysis. The study consisted of 6 treatments, blank control, negative control, positive control, A. marina leaf extract concentration of 15%, 25% and 35%, A. marina leaf extract in each treatment were significantly different (P <0.05). Diameter of clear zone produced at a concentration of 15% obtained an average value of 12.25 ± 5.37 mm, at a concentration of 25% 24.4 ± 1.41 mm, at a concentration of 35% 30.37 ± 0.95 mm. While the positive control 42.5 ± 0:00 mm. But the blank control and negative controls do not form clear zones. Based on these results it can be concluded that there are indications A. marina leaf extract in suppressing the activity of Vibrio spp. were tested in vitro.Keywords: Leaf of A. marina, Vibrio spp., Mangrove crabs (Scylla serrata),                 in Vitro

Abstract

Information on morphological characters is very important to know because it became the basis for the conventional cross-breeding to obtain superior quality seeds. Sampling was done by using Purposive Random Sampling at five stations namely Kota Tarakan, Ketapang, Takalar, Trenggalek and Demak. Based on the results Meretrix spp. as many as 84 individuals were grouped into 12 variations of hues. Specimens obtained grouped into three species, namely M. meretrix has the characteristics of a thick shell structure, strong and shiny. The size of the inner shells posterior margin is longer than the anterior margin. Margin dorsoposterior flat and angle ventroposterior form a triangle. Dorsoanterior margin slightly concave and ventroanterior corner in a half ellipse; Meretrix lusoria have characteristics size inner shells posterior margin is longer than the anterior margin. Margin dorsoposterior flat and angle ventroposterior form a triangle. Dorsoanterior margin slightly concave and ventroanterior corner in a half ellipse; Meretrix sp. has characteristics similar to M. meretrix overall but there are differences that have color variations on the internal shell (black-purple), it is different with the character of the Genus Meretrix Keywords : Meretrix meretrix, Meretrix lusoria, Clams Morphological.
