Abstract

Mesocarp fiber of oil palm is an industrial waste that can be processed into pulp, but this fiber still contains oil with various levels. The oil content in fiber influences the amount of cooking solution required to make mesocarp waste into pulp. This research consists of two stages, namely the pretreatment stage of oil extraction to obtain various oil contents in the mesocarp fiber waste and the delignification stage using the ethanol-soda solution with various ratios of solid/solvent 1: 8, 1:10, and 1:12. The analysis result of oil content shows that the fiber used contains 9.50% oil. To vary the oil content, the fibers are soaked in ethanol at room temperature until the levels drop to 7.60%. The soaking at 313,15 K can reduce the oil content down to 2.50%. The obtained pulp had the largest cellulose content 50.77% from the result of fiber delignification with 7.60% oil content and solids/solvent ratio: 1:10. While the lowest lignin was 7.39% obtained at 2.50% oil content. In the delignification with ratio 1:12, pulp cellulose decreases and from Fourier Transform Infrared Spectroscopy, it is known that it occurs because some cellulose is degraded during the delignification.
