Abstract

INDRI TAMARA PULUNGAN: Comparative Test of Recycled Paper Composition Based on Organic and Inorganic Waste, supervised by RISWANTI SIGALINGGING and SAIPUL BAHRI DAULAY The amount of waste in Indonesia is increasing every year, especially paper and plastic waste. Therefore, special handling is needed to reduce the amount of waste produced. The paper production from organic and inorganic waste is an ideal way to overcome the problem. This research aimed to determine the appropriate composition of raw materials in the processing of recycled paper using leaf, plastic and paper waste as materials. This study was conducted in March to July 2017 at the Agricultural Engineering Laboratory, Faculty of Agriculture, Universitas Sumatera Utara and the testing of tensile strength, water absorbency and tearing resistance was done at the Large Hall of Pulp and Paper, Bandung. The method used was an entirely randomized design with 2 factors which were the differences in composition and the type of leaf. The parameters observed were gramature, tensile strength, water absorbency, and tearing resistance. The result showed that the waste composition influenced on the gramature, tensile strength, water absorbency, and tearing resistance. Paper produced was categorized as art paper with the best result was KPS2 i.e 65% paper waste, 5% plastic waste, and 30% mustard with 480 g/m2 gramature value, 2.77 kN/m tensile st
