Preparation of Ganyong (Canna discolour) Starch Bioplastic with the Addition of Sirih (Piper betle) Leaf Extract

Abstract

Bioplastic production of canna starch with the addition of sirih leaf extract has been done. This study aims to determine the relationship between the additions of sirih leaf extract to the physical properties of canna starch bioplastic. Bioplastic characteristics were studied by measuring thickness, tensile strength, elongation, modulus young and wvtr. This research was conducted in three stages, the extraction of sirih leaf, preparations of canna tuber bioplastic and canna tuber bioplastic with the addition of sirih leaf extract. The results showed that the bioplastics had a thickness of 0.083 mm, a tensile strength of 3.11 mpa, 27.62′ elongation, modulus young 0,1126 mpa and wvtr 7.24 grams / m2 hour. The addition of sirih leaf extract has a strong effect on changes in tensile strength, elongation, modulus young and wvtr
