ABSTRACT

Background of the research: Pineapple leaves are treated as waste after harvesting processes. The abundance of pineapple leaf wastes must improve its value as a biosorbent in reducing the parameters of peat water. The study aimed to characterize and utilize pineapple leaf wastes to purify peat water. The pineapple leaf waste was turned into a biosorbent and activated by adding 9% NaOH. Changes in the characteristics of the active biosorbent were analyzed based on Indonesian Standard (SNI) No. 0.06-3730-1995 in terms of the water content, ash content, Iodine adsorption capacity, and methylene blue adsorption capacity. FTIR was used for determining functional groups. Scanning Electron Microscope-Energy Dispersive X-ray Spectrophotometer (SEM-EDS) was used to determine the morphology and composition of the biosorbent. The results showed that the pineapple leaf biosorbent had a water content value of 0.53%, 7.11% ash content, 23.4778mg/g methylene blue adsorption capacity, and 197.3463mg/g iodine adsorption capacity. Functional groups of pineapple leaf biosorbent before and after activation were O-H stretching, C-H aromatic, C-H aliphatic, C=O carbonyl, C=C aromatic, and C-O. The elements contained in the pineapple leaf biosorbent before activation were C, O, N, Mg, Cl, K, Fe, and Ca. Otherwise, after activation Mg and Cl elements disappeared. Conclusions: The results showed that pineapple leaf biosorbent was quite good in improving the quality of peat water. Physical parameters include odor, color, and total suspended solids, but pH value slightly increased. However, pineapple leaf biosorbent has not been able to reduce total dissolved solids.
