“…The low tensile strength for all bioplastics is due to the addition of glycerol. The addition of glycerol reduces in the strength of the intermolecular forces so that the mobility between the molecular chains increases (Hamzah et al, 2021). However, these findings suggest that adding Al2O3 to bioplastics can increase their tensile strength.…”

Sago hampas are a waste with a high starch content. The starch from sago hampas can be used as a raw material for bioplastics. However, because bioplastics have a lower heat resistance than conventional plastics, additives are required to increase heat resistance. Aluminum oxide can be used as a metal compound that acts as an additive to increase heat resistance. Bioplastics were created using a weight percentage of 0, 1, 3, and 5% Al2O3. DTA was used to determine the melting point of bioplastics, as well as their mechanical properties, density, and water resistance. The best results were identified using FTIR and SEM. The results showed that adding Al2O3 at 1, 3, and 5% increased the heat resistance of bioplastics with melting points of 270, 274, and 280 oC. Except for mechanical properties, the best results were obtained with a melting point of 280 oC, tensile strength of 3.41 Mpa, elongation of 38.66%, density of 5.52 g cm-3, and 80.28% water resistance for bioplastics with 5% Al2O3 that suitable on Indonesian National Standard 7188.7:2016. The FTIR analysis revealed that bioplastics containing Al2O3 experienced physical interactions. Morphological analysis revealed that Al2O3 was evenly distributed on the bioplastic's surface.

“…Additionally, using more plasticizers results in higher water content in biodegradable plastics, and impacts their tensile strength [16]. More water molecules can also act as plasticizers in biodegradable plastics, with a high glycerol content which can reduce tensile strength and increase elongation at break [17]. Figure 2 illustrates that increasing in glycerol concentration leads to an increase in elongation of biodegradable plastics.…”

This research investigated effect of morphological, mechanical and physical properties on biodegradable plastic made from porang starch with chitosan using, sorbitol plasticizer at concentration 60 and 80 wt%, with the addition of glycerol plasticizer at various concentrations (0%, 25%, 50%, 75%, 100%), made using the melt intercalation method with a gelatinization temperature of 80°C and drying temperature of 70°C. Plasticizer was added to improve flexibility and water absorption of biodegradable plastic properties. Increasing the concentration of the plasticizer resulted in an increase in the elongation of the biodegradable plastic. The biodegradable plastic showed greater tensile strength before addition glycerol plasticizer 1,9191 MPa at 60% concentration and 1,3018 MPa at 80%. Conversely, the addition of 100% glycerol concentration showed an increase in elongation of 77.7764% at 60% sorbitol and 171.0562 at 80% sorbitol. SEM characterization results still showed agglomeration and FTIR not showed any new functional groups. The results of this research indicate that the percentage and kind of plasticizer influence the physical, mechanical, morphological and degradation properties to porang starch biodegradable plastics.

“…Giserol juga bersifat ramah lingkungan karena senyawa ini dapat dengan mudah terdegradasi oleh mikroorganisme. Disamping itu semakin banyak gliserol yang ditambahkan maka elogasi bioplastik semakin meningkat (Morina et al, 2023), namun tidak dapat meningkatkan karakterstik ketahanan air dan laju transmisi uap (Hamzah et al, 2021), serta kuat tarik (Haryati et al, 2017). Oleh karena itu perlu dilakukan suatu penelitian yang mengkaji pengaruh variasi penambahan gliserol terhadap karakteristik bioplastik yang dihasilkan.…”

Bioplastics are packaging that can be degraded naturally by the environment. Tofu liquid waste, which has a high content of organic materials such as protein, can be used as raw material for bioplastics. The use of tofu liquid waste as a material for forming bioplastics has yet to produce bioplastics with good characteristics. Therefore, the production of bioplastics requires other constituent materials, including glycerol, as a plasticizer. This research examines the effect of variations in the addition of glycerol on the characteristics of the bioplastic produced. This study used a completely randomized plan with five treatments and three replications. If there is a fundamental difference, continue with Duncan's New Multiple Range Test at a significance level of 5%. The research results show that variations in the addition of glycerol significantly affect the values of tensile strength, elongation, modulus young, water absorption, and biodegradation of the bioplastics produced. The addition of 7% glycerol was the best treatment, with an average thickness value of 0.175 mm, tensile strength of 12.2 MPa, elongation of 15.93%, modulus young of 0.76 MPa, water absorption of 52.54%, and biodegradation of 8.26%/ day.
