This study aimed to produce a potential bioplastic film using extracted lignin from coconut husk and extracted chitosan from white leg shrimp shells with different concentrations. The research methodology used an experimental design that involved four tests to investigate the significant differences between different concentrations of the bioplastic film. The bioplastic film was made with several processes, such as pretreatment of both variables, delignification of coconut husk, and three major steps of extraction of chitosan: demineralization, deproteination, deacetylation, and production of bioplastic film. The result showed that Concentration C, which contains 25% lignin and 75% chitosan, has the most effective bioplastic film in terms of thermal behavior. Thus, the first null hypothesis was rejected because it showed that there was a difference between different concentrations. The test results also showed that there was a significant effect of different concentrations in terms of heat resistance since the table f=5.14 is less than the computed value f=7; however, there was no significant difference in terms of the tensile strength, water absorbability, and biodegradability of the film. These indicated that, with regard to the second hypothesis, the null hypothesis was rejected with regard to heat resistance and accepted with regard to tensile strength, water absorbability, and biodegradability. The potential of the bioplastic film can contribute to the environment and the field of science by reducing waste production and generating new findings. This study concluded the potential of coconut husk and white-leg shrimp shells as bioplastics.
