SINTESIS BIOSEMIKONDUKTOR MENGGUNAKANSERAT NATA DE CASSAVA DARI LIMBAH CAIR TAPIOKA

Abstract

Fiber of nata de cassava, one of biodegradable materials, has a fiber crystallinity formation and a good physical structure which is suitable to be developed as a super strong material. The purpose of the current study was to investigate the quality of biosemiconductor prepared from nata de cassava. In this study, filler Zink Oxide (ZnO) and catalyst resin were introduced into nata de cassava fibers by using handly up method. Tensile strength testing was carried out following the ASTM D-883 method. The results of the tensile strength test that has been carried out showed an elastic modulus of 2.68 Gpa, while the results of the largest tensile strength test were obtained from a mixture of fiber, ZnO, and also a resin of 316 MPa. The advantage of biocomposite made from nata de cassava fiber is that it has a low density compared to fiber products in the market that is equal to 0.108 g / cm3. One important component in electronic technology is made of a material known as semicoductor. Therefore, it is very important to develop environmentally friendly semiconductor materials. Semiconductor materials can be made from polymers doped with ZnO. This biocomposite can be classified as a semiconductor material because it has a conductivity value in the range of 10-8-103 S / cm.
