KAJIAN DELIGNIFIKASI PULP FORMACELL DARI TANDAN KOSONG KELAPA SAWIT MENGGUNAKAN HIDROGEN PEROKSIDA (H2O2) DALAM MEDIA ASAM ASETAT
ABSTRACT: The waste of palm oil industry that can be used as raw
materials for pulp making industry is palm oil empty fruit bunches. The common
method used in the pulp production process is Formacell. However, formacell process produced dark pulp
because of high lignin content.
Therefore it needs further process called delignification. This process utilized H2O2 in acetic acid media
to improve pulp qualities. The aim of
this research was to determine the effect of different concentrations of H2O2
in acetic acid media on the characteristics of pulp formacell from palm oil
empty fruit bunches. The experiment was
arranged in a Complete Randomized Block Design with a single treatment and 3
replications. The treatment was nine
levels of H2O2 concentration ( 0%, 3%, 6%, 9%, 12%,
15%, 18%, 21%, 24%) in acetic acid media at a temperature of 85oC for 3 hours.
The data homogenity and additivity were
analyzed using Berlett and Tuckey
Tests, then they were analyze for ANOVA to see any difference in the data and
then tested further using Ortogonal Polinomial. The results showed that the
concentration of H2O2 in acetic acid media had significant effect on yield,
cellulose, hemicellulose, lignin, and color of pulp from palm-oil empty fruit bunches. The result of ortogonal polynomial test
showed the increase in concentrations of H2O2 in acetic acid media linearly
decreased yield and hemicellulose, linearly increased organoleptic color
score, quadratically decreased lignin
content , and quadratically increased cellulose until concentration 50% of H2O2
in15% acetic acid media, beyond that,
the cellulose content
decreased. The best results showed that
50% of H2O2 in 15% of acetic acid media cooked for 3 hours gave the best pulp.
This pulp contained cellulose, hemicelluloses and lignin of 84.494% 6.319%
and 5.691% . The yield
was 84.85%, and the average organoleptic score for color was 4.
