Abstrakt: The increasing use of synthetic plastics has a negative impact on the environment because it cannot be degraded by nature. The current work investigates the effect of storage time of biodegradable plastic porang starch with glycerol plasticizer on mechanical and thermal properties. The effect of the storage time of biodegradable plastic on the mechanical properties of tensile strength and elongation is decreasing every week but still meets the standards at all concentrations of glycerol plasticizer up to four weeks of storage with tensile strength values of 7,137 MPa, 4,541 MPa and 2,657 Mpa and elongation values 58,574%, 47,324 %, 74,699%. The effect of storage time on the thermal properties of TGA-DTA analysis in the third and fourth weeks of thermal stability began to decrease with a total mass reduction of 9,934 mg and 9,954 mg, respectively. The degradation ability test showed a decrease in mass every week. SEM and FTIR test analyzes were also carried out. The results showed that biodegradable plastic porang starch is suitable for packaging applications because it still meets the standards until the fourth week of storage time. [ABSTRACT FROM AUTHOR]
