Synthesis and characterization of biofilm from Jatropha Curcas L., Chitosan, and Gelatin by blending method

Based on the rapid development of science, it is known that the Jatropha Curcas L., Chitosan, and Gelatin are natural materials which have various benefits. The aim of this research is to determine the characteristic of blend of Jatropha Curcas L., Chitosan, and Gelatin as a biomedical application. The blending material is obtained in the form of film / layer as a preliminary review of the research This research is experimental and the process in this research consists of 2 steps i.e. variation of gelatin composition and variation of chitosan composition. The samples obtained were characterized by tensile test to determine the value of tensile strength, strain, and Young's modulus. The best result of it was tested by FTIR, then it’s solubility also was tested. Based on the tensile strenght test, gelatin which can improve the chitosan properties are rigid and brittle. The composition of 2: 8: 12 which has a value of tensile strength, strain, and Young's modulus is low while the composition of 2:12:10 is high. Based on the FTIR test, there are extension and shift of OH group at wave number 3428,4; 3447.2; and 3447.2 cm-1. In the solubility test was found that the composition of 2: 8: 12 has the highest solubility while the composition of 2:12:10 has the lowest solubility
