ABSTRACT
This study aimed to determine the difference of paper production from rice straw (Oryza sativa) and cogon grass (Imperata cylindrica), two types of grass. The researchers compared the characteristics of the produced paper and determined which of the two materials was more efficient to use. The rice straw and cogon grass were boiled and crushed to extract the pulp. The samples that were produced were then tested and analyzed. The paper pulp of both grass species were compared in terms of their firmness, oil retention, and water retention. T-test was used to analyze the gathered data. Results showed that there was no significant difference in the breaking strength, oil retention and water retention of the paper produced from cogon grass and rice stalk.
