Conventional plastic has become a concern because it is a problem for the environment. Bioplastics made from starch and natural polymers such as cellulose from coconut fiber can be a solution to these plastic problems. This study aims to synthesize and characterize bioplastics made from durian seed starch with sorbitol as a plasticizer and coconut coir cellulose as a filler. https://www.fitnessgravesyardes.shop/product-category/wheel-insert/
