| Abstrak ABSTRACT This study aims to obtain the concentration of phosphate palm starch that produces the best bioplastics. The research was carried out at the Agricultural Product Technology Laboratory, Faculty of Agriculture, Tadulako University, Palu, from September to October 2020 which was suggestions for clarity using a Completely Randomized Design (CRD) and Randomized Block Design (RAK) with modified palm starch phosphate concentration treatment consisting of 11 levels, namely 6 %, 6.5%, 7%, 7.5%, 8%, 8.5%, 9%, 9.5%, 10%, 10.5% and 11% (w/v) with 3 replications So there are 33 experimental units with one factor. Research parameters Include thickness, water absorption, oil absorption, water vapor transmission rate, tensile strength, elongation, elasticity, biodegradation, and sensory. The results showed that the concentration of 8% palm starch phosphate gave the best characteristics. The thickness of the bioplastic increased with the increase in the concentration of palm starch phosphate. Water absorption, oil absorption, water vapor transmission rate, Young's modulus, and tensile strength decreased with increasing concentration of phosphate palm starch. The value of biodegradation and elongation of bioplastics was stable as the concentration of palm starch phosphate increased. The sensory suggestions for engagement of bioplastics tend to increase with the increase in the concentration of phosphate palm starch. Keywords: Bioplastic, Palm Starch, Physical, Mechanical and Sensory Characteristics. |
