| dc.description.abstract | The oil palm industry produces solid waste such as oil palm fronds
(OPF) and empty fruit bunches (OPEFB), but the utilization of the
OPEFB waste is still limited to composting. Even the palm fronds are
only left on the farm without being processed. While both types of waste
contain a lot of cellulose and can be processed into more economic
value. In addition to compost, the two types of waste can be used as
pulp and paper. Hence, in this study, the two wastes are processed into
the paper with a variety of concentrations of solvents and mixtures. The
aim is to determine the effect of solvent concentration in the process of
making paper pulp and the effect of the comparison of the mixture of
paper pulp with the characteristics of the paper produced. Each
material is processed into pulp by the soda process using sodium
hydroxide as a solvent. While the solvent concentration used is 20%,
30%, and 40% for materials from OPEFB, while the material from OPF
is only mixed with 20% sodium hydroxide solution. Then the pulp,
OPEFB pulp with various variations of solvent, mixed pulp with the
ratio of OPF pulp and OPEFB pulp of 1: 3; 1: 1; and 3: 1 processed
into paper. The resulting paper was analyzed to study folding strength,
tear strength, and paper thickness. The results of the study prove that
the folding endurance and tear resistance of the paper have smaller in
the greater concentration of the solvent. By contrast, the thickness of
the paper is greater. Besides, more the mass of OPEFB in the pulp
mixture, then the folding endurance and tear resistance of the paper
have less, while the thickness is decreasing. | en_US |
