Pineapple leaf were potentially used as an alternative source of adsorbent because of high cellulose content. This research aims to determine the characteristics of pineapple leaf carbon activated using microwave irradiation and determine the adsorption capacity of activated pineapple leaf carbon in adsorbing methyl orange dye. Pineapple leaf carbon was made through a carbonization process for 2 hours at 400°C. Pineapple leaf carbon was delignified using NaOH 9% to separated lignin and cellulose. Pineapple leaf carbon before and after activation used microwave irradiation (500, 600, and 700 W) was characterized based on SNI No.06-3730-1995 quality standards which included water content, ash content, iodine adsorption capacity, and methylene blue adsorption capacity. The activated carbon adsorbent from pineapple leaf was contacted with methyl orange dye used batch method at a concentration of 50 ppm for 15 minutes with variations in adsorbent mass (0.05; 0.10; 0.15; 0.20; and 0.25 g). Absorbance dan wavelength determination of the solution was carried using UV-Vis Spectrophotometer. Function group of adsorben was analysed using FTIR, surface morphology and element content was analysed using SEM-EDS. The research results showed that the optimum microwave irradiation power to activate pineapple leaf carbon was 600 W for 6 minutes with a water content value of 4.463%; ash content of 5.23%; iodine adsorption capacity of 482.22 mg/g; and the adsorption capacity of methylene blue was 18.0323 mg/g. The best efficiency adsorption of methyl orange dye was 58.8233% on a mass of 0,20 g. Based on this research, it could be concluded that the microwave activation process was not good in improving the quality of carbon in adsorbing dyes due to the destructive effect of pineapple leaf carbon.
