Efek Waktu Karbonisasi Biomassa Kulit Durian (Durio Zibenthinus) Terhadap Karakter dan Kesetimbangan Adsorpsi Biru Metilen dari Arang Aktif Kulit Durian

---

The biomass of durian peel has been successfully transformed into an adsorbent based on activated charcoal on a laboratory scale, due to its high cellulose and hemicellulose content. This research aims to study the characteristics of activated charcoal obtained from the carbonization process inside a furnace at a temperature of 300ºC with durations of 30, 60, and 90 minutes, resulting in durian peel charcoal AKD 30, AKD 60, and AKD 90. The activated charcoal is characterized by yield, moisture content, ash content, determination of surface moisture of charcoal, determination of pH zero point of charge (pHzpc), functional group analysis using FTIR, surface morphology and elemental composition using SEM-EDS, as well as crystallinity degree using XRD. The activated charcoal is then applied to adsorption tests on methylene blue solution with variations in concentration (50, 75, and 100 mg L-1), pH variations, adsorbent dosage variations, studying suitable isotherm models, and calculating surface area. The results of the moisture content test show that the longer the carbonization time, the lower the moisture content, while the ash content test does not meet quality standards. The crystallinity obtained for AKD 30 and AKD 90 is 1.45% and 1.28%, respectively, and the longer the carbonization time, the lower the crystallinity produced. The surface morphology indicates that as the carbonization time increases, the pores become more formed, and the carbon
(C) weight produced becomes larger. The intensity of functional groups decreases with increasing carbonization time. The optimum condition for methylene blue adsorption at an adsorbent dosage of 0.05 grams is as follows: AKD 30 97.9339%, AKD 60 97.5612, and AKD 90 97.0122%. The adsorption isotherm test shows a regression value close to 1, namely in the Langmuir isotherm equation with an R2 value of 0.9971. The longer the carbonization time, the larger the surface area produced. In conclusion, durian peel activated charcoal is capable of adsorbing methylene blue.
