“…The greater the concentration of modified starch, the more modified starch is formed so that the mechanical properties of bioplastics are stronger and difficult to break because it requires a large amount of energy to break it, therefore increasing the concentration of modified starch will increase the tensile strength of bioplastics. This is supported by Apriyani and Sedy (2015) who state that the addition of starch concentration will bind more hydrogen, making it difficult to break [12]. The hydrogen bonds formed to cause the film to become less flexible and become hard.…”

The massive plastic production in Indonesia is an effort to meet the demand for the food packaging sector, which is nearly 40% of the total plastic demand. Plastics are not environmentally friendly because they are not degradable. Carrageenan-based biodegradable packaging in the form of bioplastic is an alternative, but it has disadvantages such as low resistance to water. Modified starch can be used to improve bioplastic characteristics. This research aimed to determine the application of modified starch in biodegradable packaging to its biodegradability and mechanical properties. This research is experimental which consists of primary parameters and supporting parameters. The independent variables used were modified starch (0, 1, 1.5, and 2 g). The experimental design used a completely randomized design (CRD) and data analysis using the Analysis of Variance (ANOVA) and the DMRT follow-up test. The results showed that the application of modified starch in biodegradable packaging based on carrageenan had a significant effect (p <0.05) on water resistance and the best test results were 2 g of modified starch (P3) with a water resistance value of 50.96% ± 4.86. Meanwhile, the results of biodegradability, tensile strength, and elongation were not significantly different.

Biodegradable plastic is an environmentally friendly plastic; most of the components come from renewable raw materials. Biodegradable plastic can be made from starch derived from waste such as jackfruit seeds. Biodegradable plastics made only from starch have poor physical and mechanical properties, so adding reinforcement such as cellulose is necessary. One of the wastes that contain cellulose is rice straw waste. This study aimed to obtain the best ratio of jackfruit seed starch and rice straw cellulose to biodegradable plastic’s physical and mechanical properties. This research was carried out experimentally using a Completely Randomized Design (CRD) with five treatments, namely the ratio of starch and cellulose PS1 (1:0,3), PS2 (1:0,4), PS3 (1:0,5) PS4 (1:0,6), and PS5 (1:0,7) with three repetitions, 15 experimental units were obtained. The data obtained was analyzed statistically using analysis of variance (ANOVA). If Fcount ≥ Ftable data is obtained, it will be continued with Duncan’s Multiple Range Test (DMRT) at the 5% level. The selected treatment was PS5 (starch ratio 1:0,7 cellulose) with had water absorption rate of 34,82%, water vapor transfer rate of 19,12 g/m2hour, tensile strength of 20,21 MPa, elongation of 5,33%, and biodegradation for 6 days. The results showed that the addition of rice straw cellulose had a significant effect on the value of water absorption, water vapor transfer rate, tensile strength, elongation and biodegradation of the resulting biodegradable plastic.

“…The addition of glycerol resulted in the large number of OH groups it had, so it was very possible for the edible film to bind with water and result in a change in the location of the functional groups [24]. The occurrence of this kind of wave number-shifting process indicated a polymerization reaction of biodegradable plastic materials during blending [25]. Based on the results of the FTIR test above, it showed that there are new functional groups, this was because the addition of plasticizer resulted in edible films occurring chemically.…”

The study aims to determine a gelatin-xylitol edible film with the addition of butterfly pea extract (Clitoria ternatea L) using the Microwave Assisted Extraction method with optimal physical characteristics of the edible film. The research method uses the experimental method with calculations using a Completely Randomized Design (CRD), followed by Duncan analysis (DMRT) if there are significant or very significant effects in each treatment. This research method focuses on differences in the percentage of butterfly pea extract in the manufacture of gelatin-xylitol edible films with 5 treatments P0 (0%), P1 (1%), P2 (2%) P3 (3%), and P4 (4%) and 3 repetitions. The results of the second phase of the study showed the effect of different butterfly pea extracts on edible gelatin-xylitol. There was no significant effect (P>0.05) in the sedimentation test, L and a color, there was a significant effect (P<0.05) in the b color test analysis and in the antioxidant test analysis. The functional groups identified in the eggplant extract were alkanes, alkenes, fluorides, and aromatics. The analysis of the Scanning Electron Microscope test showed the presence of particles in the edible film was 3% addition of butterfly pea extract produces an edible film that has antioxidants.
