EFFECT OF TALLAS-GLUCOMANAN COMPOSITE MATERIAL COMPOSITE VARIATIONS ON BIOPLASTIC CHARACTERISTICS

The general objective to be achieved from this research is the use of taro starch as a bioplastic raw material that has been made previously. The resulting bioplastics still do not meet the requirements in terms of mechanical properties, especially in tensile strength. In this research, taro starch composites will be made with glucomannan using 1% glacial acetic acid solvent added with ZnO filler. The type of plasticizer used is glycerol. The study used a randomized block design with a total of 3 with 5 levels of composite material variation, namely the ratio of taro: glucomannan starch (in% w / w). The variations of the composite material are (taro starch: glucomannan) 80: 20; 75: 25; 70: 30; 65: 35; and 60: 40. The parameters observed were tensile strength, elongation at break, Modulus Young, thick development, FTIR and duration of degradation.
