Experimental research was carried out to obtain formulations of corn husk and sugarcane bagasse to produce good quality seed paper packaging. The differences in the raw material formulations used were (70% corn husk : 30% bagasse), P2 (50% corn husk : 50% bagasse) and P3 (30% corn husk : 70% bagasse). The research data were analyzed using ANOVA and for each treatment that was significantly different it was continued with the Duncan Multiple Range Test (DMRT) at the 5% confidence level. The results showed that corn husks and bagasse could be used as raw materials for paper, with a characteristic of yellow to brown in color, and were able to be formed into paper pouch packaging. Based on statistical analysis using ANOVA at α level of 5%, P3 treatment (25% corn husk : 75% bagasse) is the best treatment which produces paper packaging with the strongest tensile strength (12.1 N), the best elasticity (14.4%), as much as 65% can decompose in the soil after being planted for 4 weeks, and the seeds managed to germinate on the 9th day after the paper was planted.

“…Based on the previous data analysis, the degradation of plastics resulting from the addition of acetic acid concentration to the mixture of corn starch and glycerol concentration takes a longer time. This is because the addition of acetic acid concentration to cornstarch and glycerol concentration increases the time required for the bacteria to break down the biodegradable plastic [19]. Based on figure 6.…”

Almost all countries face the problem of plastic waste due to the large production of conventional plastics and the long degradation process. Therefore, to protect nature from the accumulation of plastic waste, research on biodegradable plastics needs to be done. Biodegradable plastics are made from starch, cellulose, chitosan, and proteins extracted from renewable biomass. Starch for making biodegradable plastics can be obtained from plants, one of which is corn. This study aims to determine the effect of the composition of acetic acid, glycerol and corn starch on the quality of biodegradable plastics which include tensile strength, elongation and biodegradation. The independent variables were variations of acetic acid and glycerol. Control variables are plastic mold size, corn starch mass of 5 grams, other compounds outside the independent variables. The dependent variable is tensile strength, elongation and biodegradation. To test the tensile strength and elongation of biodegradable plastic, Ultimate Testing Machine Mini was used. The results showed that the addition of acetic acid and glycerol to the corn starch and glycerol blending material had an effect on increasing the tensile strength value and reducing the elongation and biodegradation values of biodegradable plastics. The highest tensile strength value is 50.04 Mpa, obtained from the addition of 1.44% acetic acid and 35.71% glycerol from a volume of distilled water of 70 ml. The highest length gain or elongation of 90% was obtained from the addition of 0.48% acetic acid and glycerol as much as 21.43% of the 70 ml volume of distilled water. Percent weight loss of the largest plastic obtained from the addition of acetic acid as much as 0.48% and glycerol as much as 21.43% of the volume of distilled water as much as 70 ml, which amounted to 93.33%.
