MICROCOMPOSITE MADE FROM CORNCOB AND POLYPROPHYLENE PLASTIC WASTE
Abstract
Microcomposite is a material that formed from a combination of two or more material
through the mixing not homogeneous matrix that consisting of a protector and filler.
Corn cob is one of the plants that contain cellulose. Pure cellulose material derived from
corn cobs can be an alternative filler materials because of the nature of the fiber is strong
(high modulus) resulted in a crystalline structure. The purpose of this study was get the
best ratio between corn cobs and Polyprophilene Polymers (PP) viewed of texture,
porosity and adhesion. The processed consist of four stages, namely pulverizing corn
cobs and analyzed the water content and density, cellulose fraction corn cobs,
manufacture PP matrix of waste and casting microcomposit. The results showed the
water content of the corn cob’s powder 3.33% with a yield of 37.5% and a density of 0.57
g /ml and the best is microkomposite MKJ 3 (5 g of corn cob filler and matrix waste
plastics PP 5 g).
