Abstract

It has been conducted a research, which it aims to know the antibacterial and biodegradation nature of EDTA-Ag and chitosan immobilized silica composite plastics. Silica used was from rice hull processing products. Chitoson used was 0.3 and 0.7 g. Antibacterial assay was conducted over Staphylococcus aureusandEscherichia coli bacteria. the result obtained showed that the biggest inhibitory is at variation of chitosan 0.7 g, which over Staphylococcus aureusbacteria is 15.6 mm and Escherichia colibacteria is 16,7 mm. While, in biodegradation assay, the highest degradation percentage is at chitosan variation 0.3 g, namely 32.17%.

Abstract

It has been done a study of mono acyl glycerol compound synthesis through partial transesterification of castor oil (Ricinus communis L.) using KOH as catalyst. The product of mono acyl glycerol obtained is 45.4 % with the ratio between castor oil triglyceride and methanol 1:2 at 35 0C temperature with the amount of catalyst 0.5 % (b/b) from the reactant total weight and the reaction time 30 minutes. In this research, it was done a compound characterization using, TLC, FTIR and LC MS to prove the success of targeting compound has been synthesized.
