Abstract

The objective of the study is to determine the mechanical strength of chicken feather and sawdust waste in making biocomposites. The use of natural fibers because they are cheap and environmentally friendly. Preparation of biocomocytes with several folume fractions. Making biocomposite with several volume fractions using polyester resin matrix and natural fiber reinforcement of sawdust and chicken feathers. The study was conducted by making 5 volume fraction specimens. Specimen 1 (matrix polyester 80%, chicken feather 20%, and sawdust 0%) specimen 2 (80%,15%,5%) specimen 3 (80%,10%,10%) specimen 4 (80%, 5%, 15%) specimen 5 (80%, 0%, 20%).Testing of biocomposites with the American Society for Testing Materials (ASTM) D 3039 specimen standard tensile testing using a universal testing machine. Impact testing using ASTM D 6110-18 standard specimen with impact testing machine Impact testing with ASTM D256 specimen standards with an impact testing machine. From the test results, it can be seen that the volume fraction of matrik polyester 80%, chiken feather 15%, sawdus 5%, has the highest tensile strength with 6,390 MPa. Tensile test at a volume fraction of matrix polyester 80%, chicken feather 15%, sawdust 5% with an impact strength of 0.731 joules. From the research results, it can be concluded that the same volume fraction as the tensile and impact test has a high mechanical strength. The use of the dominant fiber does not affect its mechanical strength.
