Produksi Biochar Teraktivasi Dari Pelepah Sawit Sebagai Bioadsorben Limbah Cair Kelapa Sawit
Biochar is a carbon-rich residue derived from thermal decomposition (pyrolysis) of
biomass with little or without the presence of oxygen. One of the raw materials that
can be processed into activated biochar is oil palm fronds. The aims of this study to
know the characterization of activated biochar from oil palm fronds as bioadsorbent
and study the effect of bioadsorben dosages and contact time to removal BOD, COD,
and TSS from palm oil mill effluent final discharge. Oil palm fronds was pyrolysis at
600oC for 30 min, followed by chemical activation used KOH with rasio 1:1,75
(%w/w). Variable in this study is bioadsorbent dosages of 1 gram, 2 gram, and 4
gram into 200 ml POME with contact time of 3 hours, 6 hours, and 9 hours. The
results of this study obtained specific surface area and pore diameter obtained through
analysis by the Brunauer-Emmet-Teller (BET) method are 361,286 m2/g and 3,5865
nm. Functional groups obtained through analysis by the Fourier
Transformed Infrared (FTIR) compatible with the structure of activated carbon in
general, which contains O-H, C=O, C=C aromatic, and C-H which were used as
active groups. The activated biochar produced was successfully applied as
bioadsorbent for the treatment of POME final discharge with the reduction of BOD,
COD, and TSS up to 89,46%, 90,79% and 92% at dosage of 4 gram/200 ml POME
with contact time 9 hours.
