Abstract
The production process of crude palm oil (CPO) from palm oil mills (PKS) always produces
waste, including palm oil mill effluent (LCPKS). LCPKS contains dissolved compounds can
be a problem for the surrounding environment. Total Dissolved Solid (TDS) is most
compounds in LCPKS which is composed of organic compounds and other minerals.
Therefore, processing is needed to reduce TDS of LCPKS. Activated carbon from oil palm
fronds was chosen an adsorbent in reducing TDS content of LCPKS. Oil palm fronds (PS)
are the oil palm waste, consist of cellulose and lignin which can use as a source of activated
carbon. Activated carbon was made converting oil palm fronds to be palm frond charcoal
(APS) through the carbonization process at a temperature of 600oC for 1 hour. APS was then
activated chemically using KOH with a variation of the ratio of charcoal and KOH (g/g) were
1:1 (A1M5); 1:2 (A2M5) and 1:3 (A3M3) in 100 mL of demineralization water and followed
physical activation in the microwave with 100 W of power for 3 minutes, so that obtained
activated carbon from palm fronds (AAPS). The water and ash content in AAPS were
determined gravimetrically. The result of research have shown the water and ash content in
all of AAPS is accordance to standard quality of activated carbon, SNI 06-3730-1995. The
water and ash content in AAPS activated carbon can affect the ability of this adsorbent in the
LCPKS treatment process. A3M3 activated carbon which were 1,49% of water content and
5.24% of ash can removed 65.44% TDS from LCPKS.
