Studi Kombinasi Aktivasi Koh-Microwave Pada Sintesis Karbon Aktif Dari Biomassa Pelepah Kelapa Sawit (Elaeis Gueneensis)

Palm fronds were chosen as the raw material for activated carbon due to their content of lignin, cellulose, and hemicellulose. The carbonization process took place at 600°C for 60 minutes to produce palm frond charcoal, followed by chemical and physical activation. The chemical activation process used KOH with a charcoal:KOH weight ratio (g:g) of 1:1 in 100 mL of demineralized water. The process of producing activated carbon included physical activation using an alternative method involving microwave energy. This was carried out with variations in irradiation time: 1 minute (A1D300), 3 minutes (A3D300), and 5 minutes (A5D300), all at 300 W power. This study varied the duration of microwave irradiation to evaluate its impact on the properties of activated carbon. All activated carbons were identified with the provisions of SNI No. 06-3730-1995, including yield, analysis of water content, ash content, and iodine adsorption capacity, as well as physico-chemical characterization including functional groups, crystallinity and amorphous levels, surface morphology, and elemental composition. All activated carbons identified were in accordance with SNI No. 06-3730-1995, except the iodine adsorption capacity of sample A3D300. Microwave irradiation time affected yield, moisture content, and iodine sorption capacity, which decreased with increasing heating duration, while ash content increased with irradiation time. The functional groups detected on all activated carbons by FTIR included O-H (extended), C-H (extended), C=O (extended), C=C (extended), C-H (bent), and C-O (extended). The morphology of A1D300 shows uniform pores and relatively small size with the highest elemental carbon content of 73%. Prolonged microwave duration increases carbon combustion and causes a decrease in elemental carbon (C) with heating time. In summary, the results indicate that the best-activated carbon was A1D300, with a yield of 85.04%, moisture content of 0.91%, ash content of 7.59%, iodine sorption capacity of 809.24 mgg-1, Lc/La ratio of 3.57, and an amorphous degree of 90.44%
