Karakterisasi Dan Komperatif Karbon Aktif Kulit Durian (Durio Zibethinus Murr) Hasil Aktivasi Fisika Pasca Aktivasi Kimia

---

Durian peel waste can be utilized as a source of activated carbon because it has a high cellulose content of 50-60%. This utilization can reduce the amount of durian peel waste and the negative impact on the environment. In this research, a comparative study of physical activation using a furnace with air and a furnace supplied with N2 gas was conducted. The synthesis of activated carbon began with chemical activation using KOH (1:1 g/g), and then continued with different physical activation processes in a furnace with air and one supplied with N2 gas, both at a temperature of 700°C for 2 hours, with an N2 gas flow rate of 0.2 L min-1. The resulting samples were KOH-activated durian peel (DAK), activated carbon from KOH-treated durian peel with air furnace (DAKFudara), and activated carbon from KOH-treated durian peel with N2 gas furnace (DAKFN2). Sample characteristics determined included moisture content, ash content, surface area, functional groups, degree of crystallinity, crystal size, surface morphology, elemental composition, and average pore size. The characterization results showed that the moisture content of the DAK, DAKFudara, and DAKFN2 samples were 4.66%, 1.67%, and 0.99%, respectively. The ash content for DAK, DAKFudara, and DAKFN2 were 3.13%, 6.47%, and 4.27%, respectively. The surfaces area of the DAK, DAKFudara, and DAKFN2 samples were 238.7278 m² g-1, 270.0935 m² g-1, and 6.1202 m² g-1, respectively. Functional group analysis indicated the presence of O-H, C-H, C=C, and C-O groups in each sample. The crystallinity of DAKFudara was higher than that of DAK and DAKFN2. SEM-EDX analysis showed that the surface of the samples contained pores but also many contaminant particles. Pore size determination showed that DAK had larger pores than DAKFudara and DAKFN2. The carbon content in DAKFN2 was higher than in DAK and DAKFudara. Although DAKFN2 had a higher carbon content, based on surface area and its ability to adsorb methylene blue, the DAKFudara sample was more efficient as an activated carbon for dye adsorption.
