It also gives impact toward human health. Therefore, due to awareness of the negative impact on the current plastic this study is to produce eco-friendly plastic from agriculture waste which is cassava peel. The bioplastic from cassava peel were formulated with different concentration of glycerol which are at 20 %, 30 % and 40 %, respectively. Without glycerol, as in control, the bioplastic was not formulated. Then, the characterization of the bioplastic was observed through FTIR analysis. The finding shows that each sample have similarities in spectra, thus it indicates that bioplastics have similar chemical composition in term of functional group present which are hydroxyl group in alcohol and phenol (O-H), aliphatic saturated hydrocarbon chain (C-H) and ester, ether, carboxylic acid as well as anhydride group (C-O). Other than that, the several tests had been done which are tensile strength test, water absorption test and soil burial test. For tensile strength, the results show that the bioplastic with 20 % of glycerol has the highest tensile strength (5.82 ± 1.00 MPa), Young’s modulus (99.79 ± 42.03 MPa) and tensile strain (10.34 ± 2.43 %). While for water absorption test, the highest is 40 % glycerol which is 28.64 ± 0.16 % and the lowest is 20 % (24.49 ± 0.21 %.). For biodegradable test, all sample of bioplastic are fully degraded at week 4 (100 ± 0.00 %) but the fastest is bioplastic with 40 % of glycerol followed by films with 30 % and 20 % of glycerol. Therefore, the most suitable bioplastic to be used for packaging would be bioplastic with 20 % of glycerol because the degradation is not fast as 30 % and 40 % of glycerol but still within 4 weeks and the best in mechanical properties. 2020-07 Thesis https://ir.uitm.edu.my/id/eprint/32751/ https://ir.uitm.edu.my/id/eprint/32751/1/32751.pdf text en public degree Universiti Teknologi Mara Perlis Faculty Of Applied Sciences
