“…In bioplastic composite films, high-density values indicate that biodegradable plastic films can be more effective in preventing the substances contained in them from entering the air. Likewise, the low-density value of biodegradable plastic film has a lower regularity value, so it cannot prevent small molecules from entering [15]. This is in line with research on the effect of adding betel leaf extract on the density of sago starch bioplastic [14].…”

“…A high-density value indicates that the film is biodegradable and can be more effective in preventing the substances contained in it from entering the air. Meanwhile, the density value is low for biodegradable plastic film, which has a lower regularity value, so it cannot prevent small molecules from entering [15]. The density value of the bioplastic composite can be seen in Figure 1.…”

Starch-derived bioplastics have weaker mechanical properties than conventional polymers and a short lifespan due to their susceptibility to microbial degradation. This study examines the impact of microcrystalline cellulose (MCC) and betel leaf extract on the characteristics of sago starch bioplastic composites. Microcrystalline cellulose extracted from coconut coir improves tensile strength, and betel leaf extract improves antibacterial properties. This study began by isolating alpha-cellulose from coconut coir and continued by isolating microcrystalline cellulose via the hydrolysis procedure employing hydrochloric acid. As an antibacterial, this research extracted betel leaf using 96% ethanol and a rotary evaporator. MCC variations of 0, 2, and 4(b) and betel leaf extract variations of 0, 3, and 6%(v) in 100 g of sago starch were examined. Up to 20% of the combination comprises glycerol as a plasticizer(v). MCC and betel leaf extract altered bioplastic composites’ properties. A bioplastic composite with 2% MCC and 6% betel leaf extract can inhibit the growth of Bacillus cereus bacteria. It has a tensile strength of 274,531 kPa, an elongation at break of 3.72%, a density of 0.724 g/cm3, and a water absorption of 7.79%. It concludes that MCC and betel leaf extract had an antibacterial effect in starch bioplastic composite.

Biofoam is a replacement packaging for Styrofoam made from natural fibres that are naturally biodegradable and food-safe. Many studies use chemicals and starch as a matrix adhesive in the manufacture of biofoam. In previous studies, biofoam cups have been developed using the mold Rhizopus oligosporus which is found in coconut fibre. The objective of this study was to analyse the physical, thermal and functional groups’ characteristics in order to determine the most durable biofoam cup. The mixtures of fibre, tempeh mold, and soy flour were fermented for 3 days at 35°C in two stacked plastic cups and were dried for 46 hours at 50°C to stop the fermentation process. The biofoam cups were then analysed for the physical, thermal and functional groups’ characteristics. The most favourable characteristics of the biofoam cup is not easily destroyed and resistant to heat. The results showed that it had 0.08 g/cm3 ± 0.1 g/cm3 of density and 320.54°C of thermal gravimetry analysis. It also had a hydroxyl functional group (O-H) at wave number 3273.20 cm−1, an alkyl group (C-H) at wave number 2937.59 cm−1, a carbonyl group (C=O) at wave number 1654.92 cm−1, 1535.34 cm−1, and 1259.52 cm−1, and the C-O functional group at the wave number 1060.85 cm−1.

“…According to Putra & Saputra (2020), a water uptake test is conducted to determine the presence of bonds in polymers that occur as well as the regularity or level of bonding in polymers that can be caused through the percentage of polymer weight gain after the occurrence of swelling. The water uptake percentage value of straws can be found in Fig.…”

Plastics waste has been recently recognized as one of the most critical environmental issues. The most plastic is not recycleable and it takes 300-500 years to degraded perfectly. Plastics straw also contribute these negative impacts, so develop the biodegradable straw can be one of the solution. Natural ingredients that contain carbohydrates can be used as biodegradable straw materials are unused rice and rice bran, with glycerin from used cooking oil. This study aims to find out the effects of composition of unused rice flour and rice bran flour respectively on parameters. The parameters are the tensile strength, elongation, water uptake, and the biodegradation, then compare to the control. Statistical test were used to check, analysis, and compare between the data. The results show that combination variations in raw material flour had a significantly effect (p<0.05) on tensile strength, elongation, and biodegradation, but had not significantly effect (p≥0.05) on water uptake. Results obtained from the study of biodegradable straws for tensile strength ranges from 0.21-6.19 MPa, elongation range from 0.43-1.71%, water uptake 100%, and degraded 100%. Sample with a combination of 3 g unused rice flour : 0.5 g rice bran flour, has the highest tensile strength and elongation value and degraded within 4 days. However, the sample can not be used as an alternative to plastic straw because it does not have similar characteristics.
