Abstract
Plastics were commonly used as packaging materials for primary, secondary, and tertiary needs. However, the continuous use of plastic was inadequate for the environment. The research that was developing to address the use of conventional plastics is bioplastics. Bioplastics undergo faster degradation but had low mechanical strength and were hydrophilic in nature. One of the main ingredients of bioplastics was starch. The tensile strength of bioplastics based on the classification of starch sources that tuber-based bioplastics show the best tensile strength interaction. (18,49 - 89,32). Glycerol was the most widely used plasticizer because glycerol has the best interaction ability compared to other plasticizers when combined with starches with different characters, either by adding various types of fillers or without adding fillers. The types of fillers that were commonly used are chitosan, clay and ZnO.
