Palm fronds (PS) derived from oil palm plantation waste have been developed as
activated carbon due to its abundant availability and contain cellulose and lignin.
At the same time, liquid waste is also generated from palm oil processing factories.
Color and turbidity are 2 parameters in palm oil mill effluent (LCPKS). This study
aims to make activated carbon from PS through the carbonization step followed by
chemical-physical activation and use it for reducing color and turbidity in the
LCPKS. PS carbonization was carried out at 600oC for 1 hour, to obtain palm
midrib charcoal (APS). APS was chemically activated with the ratio of APS : KOH
(g/g) being 1:1 (A1) ; 1:2 (A2) and 1:3 (A3) in 100 mL of demineral water. The
activation was continued physically using a microwave at a power of 100 W with a
time variation of 3 (M3); 5 (M5) and 10 minutes (M10). All treatments obtained 9
types of palm midrib activated charcoal (AAPS), each of which were A1M3,
A1M5, A1M10, A2M3, A2M5, A3M10, A3M3, A3M5, and A3M10, respectively.
The yield of activated carbon, moisture content, ash and volatile matter of all AAPS
were determined gravimetrically according to SNI No. 06-3730-1995, while the
lattice parameters and the degree of crystallinity were characterized using XRD to
the sample which gave the optimum value according to the SNI standard. LCPKS
were adsorbed with AAPS based on color and turbidity parameters with variations
in contact time and adsorbent mass. Results of the research have shown that yield,
moisture content and ash content are in accordance with the carbon quality standard
of SNI No. 06-3730-1995, while the volatile matter content did not meet the quality
standard of activated carbon. XRD analysis with hkl (002) and (100) which are
located at angle of 2θ 22.930o – 23.539o and 44.622o – 45.661o describes the peak
position corresponding to carbon structure, respectively. Activated carbon A3M5
(activated with the highest KOH weight) has the highest amorphous degree and
Lc/La ratio. A high Lc/La ratio correlates with a high activated carbon surface area.
However, activated carbon A1M5 with the highest crystallinity were able to reduce
the color and turbidity of LCKPS by 94.54% and 82.11% respectively at 6 hours
contact time and 2.5 g mass of activated carbon.
