Pineapple leaves are waste from pineapple farming which has the most volume of pineapple plants by 80 % which is not used optimally so that its existence can damage environmental aesthetics. Pineapple leaves have a chemical composition in the form of cellulose at 69,5 – 71,5 %; which can be used as a precursor for the manufacture of activated charcoal as an adsorbent through the process of carbonization, activation of chemical and physics. The carbonization process was carried out at 450 ºC for 30 minutes and the chemical activation stage was carried out by adding activators in the form of H2SO4 with different concentrations 0; 2,5; 5 and 7,5 % with temperature variations of 500, 600 and 700 ºC. Characterization was carried out by moisture and ash content, iodine absorption with iodometry titration, methylene blue absorbency, functional group analysis with FTIR and surface morphology with SEM. Based on the research carried out, the optimum condition of activated charcoal was obtained at a concentration of 5 % with a calcination temperature of 600 ºC with the results of water content ( 0,88 %), ash content (2,93 %), active absorption of charcoal against iodine (896,13 mg/g ), absorbance of methylene blue (9,03 mg/g). Activated charcoal was applied to improve the quality of peat water, which was viewed from several parameters including odor, color, pH, turbidity, organic matter content, and Fe metal content. The results obtained showed that the adsorbent from pineapple leaves activated charcoal was able to increase pH to neutral and improve the Fe metal content in peat water with a mass of 2 g. The results have been obtained in accordance with PERMENKES No.416/MENKES/PER/IX/1990. The parameters of color, turbidity, and the content of organic matter in peat water were can not be improved through the adsorption method using the adsorbent from pineapple leaves.
