Pengaruh Karakteristik Bioplastik Pati Singkong dan Selulosa Mikrokristalin Terhadap Sifat Mekanik dan Hidrofobisitas

Abstract

Bioplastics is one alternative to change plastic. Because bioplastics are made of biopolymers that can be degraded by microorganisms. The purpose of this study was to determine the effect of biopslastic characteristics of cassava starch with 0% cellulose content (without the addition of cellulose) and bioplastic with 10% cellulose content to mechanical properties and hydrophobicity. The characteristic of bioplastic that studied in this research was mechanic, water uptake and contact angle. The results obtained in tensile strength of bioplastics with 10% cellulose content greater than bioplastics without the addition of cellulose. The addition of 10% cellulose showed tensile strength of 14.3 MPa. Whereas results obtained by water uptake and contact angle stated that bioplastics with the addition of cellulose was hydrophilic.
