Abstract

The use of food additive such as borax has a negative effects on health, example the abuse of borax as food additive in the pempek and bakso can be dangerous for human health at Palembang city. The borax or boric acid have toxic effect on all body cells.  The purpose of the  research is to assess the effect of borax on the quantity of mice sperm, how many are the borax doses can cause decrease the quantity of sperm mice. The research  was carried out at laboratory Department of Medical biology, Faculty of Medicine Sriwijaya University Palembang using a Completely Randomized Design. The treatment group give the borax, the control group was administrated by similar volume of aquabidest only. The result showed that borax could significantly  decreased (P<0,05) the number of mice  sperm concentration compared to control  group. As  a conclusion the administration of borax at doses 4 mg/10 gr bw and 6 mg/10 gr bw on male mice by gavage in 35 days can significantly decrease the quantity of mice sperm compared to the control  group. It is suggested  to conduct further studies such as the fertility test  of mice sperm given  borax longer than 35 days by  gavage. Key words:   Borax, The quantity of sperm and Mus musculus

Abstract

Macrobenthos are animals which live in bottom substrate of waters systems ie sand, mud, rock or rubble. This research aims to determine the macrobenthos diversity in three types of swamp in Pampangan ie floodplain swamp, rain-fed swamp and mix swamp. The research was conducted from October 2011 until March 2012 by collecting primary data and laboratorium analysis. The location of the research is lebak swamp, Pampangan subdistrict, Ogan Komering Ilir Regency, South Sumatra Province while identification of macrobenthos and sediment analysis at Research Institute for Inland Fisheries. The results show that there are 3 classes of macrobenthos, ie 9 species of Insecta, 1 species of Molusca and 11 species of Oligochaeta. Highest diversity index is in floodplain swamp while highest evenness index and species richness index are in the mix swamp. Similarity index of macrobenthos on the three types of swamp are low, it means that the animals come from different community. The differences of fertility level and texture of sediment will affect the diversity of macrobenthos. Key words: Diversity, macrobenthos, swamp, South Sumatra

Abstract

The research about Isolation Antibacterial Agent of jambu Bioa’s leaves and Determinated the Minimum Inhibitory Concentartion (MIC) for Escherichia coli was conducted from September – December 2005. The isolation antibacterial agent was done at Laboratory of Genetic and Biotechnology, Biology Departemen, Faculty of Mathematic and Natural Science, University of Sriwijaya. The aims of this study were to asses antibacterial agent of Jambu bioa’s to determine the active chemical compound. The process isolation of antibacterial compounds was done in three ways : extraction by using soxhlet, fractionation by using liquid vacuum chromatographic. Antibacterial activity tested by using the agar diffusion method. The test organism were Escherichia coli. The result proved that n – hexane and aethylacetate have been examinated test bacterium Escherichia coli. Bioactive compound fraction N4, N5, N6 from n- hexane and E3, E4, E5 from aethylacetate. The active compound isolate N1 with Rf 0,22, isolate N2 with Rf 0,87 are fenol  and isolate E1 with Rf 0,6 is terpenoid.Key words : MIC, fractionation, fenol, tetracycline

Abstract

This research study aims to assess the effect of Pb2+ ion concentration on the adsorption bioadsorben derived from waste biomass in the form of peanut shell, rice husk and sawdust. This research forms a laboratory experiment with a completely randomized design 2 factor. Factor 1: variation of Pb2+ ion concentration of 0.1, 1, 10, 100 and 1000 ppm. As well as the 2 factors: the type bioadsorben: peanut shell, rice husk and sawdust. Examination of the amount of adsorbed Pb2+ ions using Spectofotometer Atomic Absorption (AAS). Adsorption results showed that the greater the concentration of Pb2+ ions, the greater the ions absorbed by bioadsorben. Optimum absorption concentration at each bioadsorben achieved at 10 ppm, with the value of each absorption is greatest in rice husk 4.036 x 10-3 mg/g, followed by sawdust 3,810 x 10-3 mg/g and a peanut shell 2.819 x 10-3 mg/g. Analyysis of 2 factor analysis showed the presence of intereaksi between Pb 2+ ion concentration variations and types of adsorbents for Pb 2+ ions are adsorption. Key words : Consentration, ion Pb2+, peanut shell, rice husk and sawdust
