Abstract

Abstract. Tilapia is an important fisheries comodity which intesively farmed in Indonesia. However, an intensive farming system of aquatic organism often lead to disease outbreak. Ones the disease emerged, it will be difficult to combat. The curing method by using antibiotics in aquatic organism will bring negative impacts, such as causing bacteria resistance and decline of aquatic environments. Therefore control of disease in aquatic organism should be done through preventive methods such as the use of β-glucan from baker’s yeast (Saccharomyces cerevisiae). It is widely known that yeast’ cell wall contain of immunostimulant substance namely β-glucan. This research was aimed to find the effect of different dose of β-glucan in diet toward the phagocytic activity, respiratory burst which is indicated by Nitroblue Tetrazolium (NBT) activity, total of protein plasm and agglutination activity of tilapia blood. Method used in this study was experiment by complete random design using five treatments triplicate. Those treatments were β-glucan 0; 2,5; 5; 7,5 and 10 ppmkg-1 diet. Result showed that the different dose of β-glucan in diet gave a significantly effect on the phagocytic activity and total of protein plasm, but not on respiratory burst (NBT activity). The highest phagocytic activity occured in treatment E (β-glucan 10 ppmkg-1 diet) with the value of phagocytic activity was 37,67%, whereas the highest of total of protein plasm was occured in treatment B (β-glucan 2,5 ppmkg-1 diet) with the value of 123,58 mgml-1. Keywords : Baker’s yeast, β-glucan, phagocytic and agglutination activity, NBT activity, total of protein plasm

Abstract

Abstract. The study on the phytoplankton community in estuary area of Aceh River was done from August to October 2006. The objective of the present study was to evaluate the structure of the phytoplankton community in Aceh River post tsunami. Explorative survey was done at three sampling sites along the river. Sampling sites were determinated based on salinity zoning; 30 ppt, 18-30 ppt and 5-18 ppt. The results show that higher diversity of the phytoplankton was found at sampling site 1, while the lower diversity was recorded at sampling site 3. There were no dominancy of species at all of sampling locatios. Diversity index was ranged between 0.95 to 0.98 and its mean that the diversity is higher at all of stations, while similarity between station 1 and 2 was higher compared to others stations.There was no difference in division composition of phytoplankton post tsunami, however, the total species was increased post tsunami.Keywords: Abundance, diversity index, similarity index, and tsunami

Abstract

Abstract: Streptomyces is one of bacterial genus which has been considered as a potential source of many novel antibiotics from both terrestrial and marine microorganism. In this paper, four secondary metabolites have been isolated and characterized from a marine Streptomyces sp. B5798, namely phydroxyphenylacetic acid (2), indole-3-carboxylic acid (3), indole-3-acetic acid (4), and Macrolactin A (5), respectively. Two of them are common compounds, namely indole-3-carboxylic acid (3) and indole-3-acetic acid (4). The 3,4 dihydroxybenzaldehyde is a degradation product of phydroxyphenylacetic (2) in microorganism. Macrolactin A (5) showed cytotoxicity against brine shrimps test (A. salina). All structures of the isolated compounds were elucidated based on spectroscopic and mass spectrometry data.

Abstract

Abstract-. Coral transplantation is one of the techniques to rehabilitate the damaged coral reefs. The objective of this study is to observe the composition of reef fishes in the coral transplantation location in Rubiah Island, Sabang. The study was conducted in February 2011. Some of reef fishes Family were found in coral transplantation location (16 Family at 3 meters and 14 Family at 10 meters). The Family of Acanthuridae, Chaetodontidae, Pomacentridae Scaridae and Labridae were found in 3 meters. Reef fish families that dominated at depths of 10 meters were the Family of Acanthuridae, Pomacentridae Scaridae and Chaetodontidae. There are 40 reef fish species found in this study (34 species in 3 m and 38 species in 10m). Some reef fishes that were found in the transplantation area suggested that coral reefs rehabilitated using the technique of transplantation can improve its function as habitat for reef fish.Keywords: Transplantation, coral reefs, Rubiah Island
