Abstract

Mercury from the traditional gold mining activities in Aceh Jaya Regency causes water source and thus residents are exposed to mercury metals. In organic and inorganic conditions, mercury is toxic to the human body, causes damage to the nerve system, kidney failure, heart failure, blood pressure disorders, and damage to the immune system. The problem of mercury contamination can be chemically solved in various ways. This research uses polyurethane foam to adsorb mercury from water. The adsorption and selectivity of polyurethane foam adsorption can be improved through modification with Chitosan. In this research, preheating temperature, glycerol and toluene di-isocyanate (TDI) compositions greatly affect the physical form of foam. The condition under which optimal glycerol composition used for synthesizing the polyurethane foams is 20% (w/w of mixture A). This glycerol composition results in polyurethane foams with an optimum ratio of the mixture A/TDI/distilled water of 2 : 1 : 1. The best adsorption is obtained with polyurethane foam added by 2.5% Chitosan. The optimum mercury adsorption 25% is resulted from the operating time of 60 minutes with adsorption capacity of 0.313 mg/g. For Chitosan modified polyurethane foam, research points out that the reaction is the second order reaction. The result concluded that the polymer has semi crystalline crystallization and melting temperatures.

Abstract: This study aims at describing the feasibility level of learning books according to the National Education Standards Agency (BSNP) and the scientific literacy level of class XII biology learning books based on 4 dimensions, namely science as a body of knowledge, science as a way of thinking, science as a way of investigation and science and its interactions with technology and society. This study uses a quantitative approach with the content analysis method. The sample in this study was the biology learning book for class XII by Irnaningtyas in the 2013 curriculum which was chosen by purposive sampling technique. The research data were obtained from the results of book feasibility and the level of scientific literacy by using book feasibility instruments according to the BSNP and a sheet of scientific literacy level analysis based on 4 dimensions. Stages of analysis were divided into 2 stages, namely the stage of book feasibility analysis and analysis of the level of scientific literacy of biology learning books. The data analysis was using descriptive statistical methods. The results of the data analysis show that the level of feasibility in the analyzed learning book has been declared feasible according to BSNP. At the level of scientific literacy, only the scientific dimension as a body of knowledge gets a good category. The results of this study can be used as material in the development of learning books based on the content of 4 dimensions of scientific literacy in balanced proportions.
