Abstract

Coconut has been known for its benefits in human life. Coconut coir, as part of coconut
which is considered as waste, contains useful components. It contains high cellulose which is could
be used in fiber industries. Meanwhile, coconut coir also contains lignin which needs to be
separated. In this study, a delignification process was used to remove the brown color on the fiber
caused by the lignin content. The delignification process was a pretreatment before the cellulose
extraction was carried out. It had been done in the various NaOH concentration (0.5; 1; and 1.5
M), reaction time (1; 1.5; and 2 hours) and the reaction temperature (60,70, and 80 oC). This study
aims to determine the cellulose content and the factor that affected the cellulose extraction and
the characteristics of the cellulose extracted from the coconut coir. The Chesson Data method and
SEM analysis have been used for the characterization of the cellulose. The delignification method
known has the potential as a simple and effective method for extracting cellulose from natural
materials. The result shows that the optimum cellulose content obtained at 100 mesh coir particle
size, 1.5 M NaOH concentration, at 80°C for 1.5 hours was 69.82 %.
