Abstract:
This research aims to determine the characteristics of activated pineapple leaf powder and
its ability to improve the physical quality of peat water which includes physical
parameters such as color, odor, pH, TDS (Total Dissolved Solid) and TSS (Total
Suspended Solid) values from peat water. Characterization of the active powder was
carried out by testing the water content gravimetrically, testing the adsorption capacity of
the active powder on methylene blue and testing the adsorption capacity of the active
powder on iodine using the titration method. The results of the characterization of
pineapple leaf powder after activation are that the water content is 0.53%, the adsorption
capacity for iodine is 230.7869 mg/g and the adsorption capacity for methylene blue is
22.8138 mg/g. FTIR shows the results of hydroxyl O=H, C-H group which is from the
cellulose structure, carbonyl C=O which indicates the presence of lignin, as well as the
functional groups C=C and C-O on pineapple leaves powder. Based on the results of the
SEM-EDS, it was found that the biosorbent pineapple leaves powder had the elements O,
C, N, Si, Ca and had an uneven texture. The results obtained after adsorption process with
pineapple leaves activated powder showed that pineapple leaf powder ware able to
increase the pH in peat water, eliminate odors and reduce the TDS and TSS values in peat
water, this is in accordance with Regulations Government of the Republic of Indonesia
No. 22 of 2021.
