“…In contrast, bioplastic with the addition of glycerol and spirulina produces more elastic bioplastic. This is consistent with the outcomes of a research conducted by (Layudha et al, 2015), where the addition of glycerol has an effect on the morphological quality of bioplastic.…”

The development of bioplastic films is one of the efforts to reduce plastic waste. The polymer used as the basic material for making bioplastic films is starch. Potato peel waste can be repurposed by extracting its starch content. This research has the purpose to investigate the influence of adding glycerol and spirulina on the characteristics of bioplastic films made from potato peel starch, and to ascertain the optimum composition of raw materials. Bioplastics were produced by casting method from potato peel starch with variations of glycerol and spirulina. The bioplastic composition in this research includes K0 (0 ml glycerol and 0 grams spirulina), K1 (2.5 ml glycerol and 0.3 grams spirulina), K2 (1.25 ml glycerol and 0.3 grams spirulina), K3 (2.5 ml glycerol and 0.15 grams spirulina), and K4 (1.25 ml glycerol and 0.15 grams spirulina). The characteristics of bioplastic films include thickness testing, tensile strength, elongation at break, and degradation. The results from the characterization of bioplastic films indicate that the addition of glycerol and spirulina is inversely proportional to the tensile strength produced, meaning it decreases. However, the addition of glycerol and spirulina is directly proportional to the percentage of elongation produced, meaning it increases. The addition of spirulina has an impact on the degradation time of bioplastic films. The optimal raw material ratio in this research is found in sample K4, with a tensile strength value of 23.038 MPa, elongation at break of 4.385%, thickness of 0.1367 mm, and complete degradation occurring on the sixth day.

“…According to Darni & Utami, 15 starch-based bioplastics are usually not water-resistant (hydrophilic), so adding hydrophobic materials like chitosan is required to improve this property. Research by Layudha et al 14 indicates that adding 2% chitosan produces optimal tensile strength, 0.076212 N/mm 2 . Synthetic food coloring is added to provide attractive colors to the product, while synthetic food flavoring creates a unique taste in the bioplastic straws.…”

“…13 The addition of glycerol acts as a plasticizer that enhances the elasticity of the bioplastic straw polymer. Research by Layudha et al 14 shows that adding 1% glycerol results in optimal mechanical properties of the bioplastic, with a tensile strength of 0.029 N/mm 2 . Chitosan is an additional polymer and antibacterial agent derived from crustacean waste products.…”

Indonesia produces approximately 2.5 liters of waste per capita daily, accumulating to 625 million liters nationwide, with continual increases due to population growth and environmental changes. This surge necessitates innovative alternatives to conventional plastics to curb plastic waste proliferation. A promising solution is developing bioplastic straws from arrowroot (Maranta arundinacea) starch, composed of 24.64% amylose and 73.46% amylopectin. The high amylose content makes it an ideal, strong, and flexible raw material for bioplastic straw production. This study aimed to explore the potency of arrowroot starch nanocrystal as an edible straw material. The concept of edible straw material utilizes nanocrystalline arrowroot starch as the main component, enhanced with chitosan as a polymer, glycerol as a plasticizer, and synthetic food colorants and flavorings. The goal is to explore and establish the process for creating non-food products from agricultural starch and assess their societal and environmental impacts. The nanocrystalline starch is extracted from arrowroot tubers using a wet method and modified through acid hydrolysis. It is then processed with water, glycerol, chitosan, and synthetic additives, heated, and molded into straws. The resulting edible straws from nanocrystalline arrowroot starch have the potential to offer unique taste, color, and thicker consistency compared to traditional plastic straws, presenting an eco-friendly and innovative alternative in waste management.
