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 | en_US |
