Abstract

Plastic waste continues to increase every year along with the increasing number of industries and population. Accumulated plastic waste has a negative impact and harm the environmental. The initiative of 3R (reduce, reuse, and recycle) has been widely promoted, but it is not optimally implemented. The use of organic materials to substitute the synthetic materials in plastic become alternative to prevent this problem continues in the future. Bioplastics are naturally decomposed by the soil and made from renewable materials. This review aims to explore the potency of cassava peels (Manihot esculenta) and seaweed carrageenan (Eucheuma cottonii) as the bioplastic material. The method used is an effective literature review and in accordance with the topic being discussed. The discussion method is carried out based on research results that have been found by previous researchers, which are then integrated with other researchers to get strong results and conclusions. Cassava peel waste and seaweed carrageenan have the potency to be made into bioplastics because they contain polysaccharide that can form a thin layer films based on gelatinization. The development of cassava peel waste and seaweed carrageenan will becoming the promising materials as substitutions for synthetic plastic, and also could help prevent the negative impact of plastic waste. Furthermore, since the cassava and seaweed are naturally abundant, it will promoting the environmental sustainability.

Abstract

Plastic waste has become a global environmental problem as it is difficult to decompose and harms the environment. The alternative solution to overcome this problem is to produce biodegradable plastics made from renewable materials. Cassava peel waste contains starch that can form a thin film but has poor mechanical properties. Therefore, it is necessary to include additional substances to enhance its strength. Carrageenan is a substance that can improve bioplastic mechanical properties. This study aims to determine the characteristics of bioplastic made from cassava peel waste starch and carrageenan formulation. Nine formulations were tested in this study using the randomized complete block design factorial with the two factors of cassava peel starch (S) and carrageenan (C) concentrations, both at three levels and carried out under three replications. Bioplastics characteristics are observed in thickness, swelling, biodegradation, tensile strength, elongation, and elasticity. The formulation S2C1 (starch 20%; carrageenan 5%) produced the bioplastic with the best mechanical properties, including a tensile strength of 1.1 MPa, elongation of 1.33%, and elasticity of 0.87. Meanwhile, the formulation S3C1 (starch 30%; carrageenan 5%) had the best results for swelling, thickness, and biodegradability, with a swelling value of 57.79%, thickness of 0.36mm, and 11-day biodegradability.
