• Heavy metal pollution was a headline issue for environmental degradation, both in water and soil environments. Reducing efforts of heavy metal can be carried out through the green system, such as activated carbon from agriculture waste. This paper investigates the properties of activated carbon from banana empty fruit bunches (BEFBs) for heavy metal adsorption. The activated carbon was produced using chemical activation under microwave-assisted. Potassium hydroxide (KOH) is used as an activating agent for concentrations of 2, 3, and 4 M, each sample denoted AC-2M, AC-3M, and AC-4, respectively. The microwave irradiation was performed by a commercial microwave oven with output power up to 630 W for 15 minutes. X-ray diffraction characterization result shows the lower stack length Lc occurs in a sample of AC-2M with a value of 10.966. The surface morphology of all samples shows the presence of non-uniformed pores. The EDX analysis reveals that carbon content of AC-2M is higher than other samples up to 78.86%, while the oxygen is lower (11.87%). FTIR spectrum shown that the activated carbon from BEFBs contain functional groups of C-H, C=C, C-C, C-OH, and CH2 at wavenumber 2887 cm−1, 2360.97 cm−1, 2339.5 cm−1, 1573 cm−1, 1393.63 cm−1, and 998.21 cm−1, respectively. As the best sample, AC-2M shows higher heavy metal adsorption as much as 87.41% for Pb and 62.35% for Cu.
