Abstract
In this research, activated carbon has been successfully fabricated using waste Cigarette of red Marlboro filters as a starting material. Through the process of carbonization and chemical activation using KOH with the aid of microwave irradiation power. The activation process used KA: KOH with the ratio of 2:1, 2:2 and 2:3 for 24 hours. Activated carbon was characterized using Scanning Electron Microscope and Energy Dispersive X-ray, X-ray Diffraction, isothermal nitrogen adsorption and absorption of methylene blue. The results of X-ray diffraction showed that activated carbon has a semi-crystalline structurs with peaks 2θ of 22,873˚ and 43,700˚. Activated carbon microstructure analysis showed that the layer height (Lc) is inversely proportional to the width of the layer (La) and the distance between the two layers of d002 and d100 which depends significantly on the number of elements used KOH. The best surface area of activated carbon produced from variation of KA: KOH with the ratio of 2:3 that was 328.13 m2/ g.
The highest absorption of methylene blue was found to be 88.7671 mg/g for the ratio of 2:3 of KA: KOH.
