Item KORELASI KEBASAAN PERMUKAAN DENGAN GUGUS FUNGSI ARANG AKTIF KULIT DURIAN(Elfitra, 2023-11) Seftiana, Zenifa; MuhdarinaDurian skin waste (Durio zibethinus) which contains quite high levels of cellulose, lignin and carbon can be used as raw material for active carbon. In this research, the characteristics of active carbon synthesized from In this research, the characteristics of activated carbon synthesized from durian peel waste were studied using a furnace at a temperature of 700oC for 2 hours to obtain KADF and microwave at a power of 750 W for 75 seconds to obtain KADM. The characteristics of active carbon determined are basicity and surface functional groups. The results of the characterization show that the surface alkalinity of KADM activated carbon is higher than that of KADF. Likewise, the -O-H functional group in KADF is lost, while the other functional groups (C-H, C=C, C-O) show a lower percent transmittance compared to KADM activated carbon. These results show that physical activation using a microwave at 750 W for 75 seconds is better than using a furnace at 700 oC for 2 hours..
