This study aimed to determine the tensile test size of the bira tuber bioplastic with the addition of kepok banana peel starch. The method used is experimental. A tensile test was carried out with ATSM D882. The research results showed that the four samples' best tensile test added the most bira starch at 40% of 1432 N/m². The color of the resulting plastic is still clear brown because no bleach is added to the starch.
