Indonesian Journal of Pure and Applied Chemistry (IJoPAC) was first established in 2018 as a scientific journal that accommodates researchers and education practitioners to publish scientific work and research results which are the results of experiments or literature studies in the field of chemistry. Publications are carried out periodically with three issues (January-April, May-August, September-December) in one volume per year. Published scientific work can be in the form of original articles, short communications and review results covering the fields of Physical chemistry, Organic chemistry, Analytical chemistry, Inorganic chemistry, Biochemistry / Biological Chemistry, Applied Chemistry. Focus and Scope of Indonesian Journal of Pure and Applied Chemistry covering the fields : Physical chemistry Organic chemistry Analytical chemistry Inorganic chemistry Biochemistry/Biological Chemistry Applied Chemistry

Abstract

The use of mangrove leaves in functional beverages is increasingly popular due to their bioactive compounds, which have potential as natural antioxidant sources. This study aimed to analyze the antioxidant activity and organoleptic quality of tea infusions prepared from Acanthus ilicifolius and Rhizophora apiculata leaves. Leaf samples were collected from the coastal area of Kubu Raya Regency, vacuum-dried, ground, and prepared as tea infusions. Antioxidant activity was determined using the DPPH method, while organoleptic quality (appearance, aroma, and taste) was evaluated through a hedonic test with 10 panelists. The results revealed that A. ilicifolius tea exhibited higher antioxidant activity, with an IC₅₀ of 9.48 ppm, compared to R. apiculata at 16.36 ppm. Both values fall into the very strong category (IC₅₀

Abstract

This study investigates the interactions between potential bioactive compounds in oil palm empty fruit bunches (OPEFB) and Pb²⁺ ions using computational methods. The identification of functional compounds was performed using Fourier Transform Infrared spectroscopy, which confirmed the presence of lignocellulosic components, predominantly lignin and cellulose, as the major constituents of OPEFB biomass. Molecular modeling was then performed using the semi-empirical PM3 method to obtain optimized structural parameters, including bond lengths and bond angles, both before and after interaction with Pb²⁺ ions. The calculated interaction energies for lignocellulose, cellulose monomer, and cellulose dimer complexes with Pb²⁺ were –56.22, –69.90, and –52.09 kcal/mol, respectively. The negative interaction energy values indicate spontaneous complex formation and thermodynamic stability. These results demonstrate that the chemical constituents of OPEFB exhibit strong potential as effective biosorbents for Pb²⁺ ions through molecular-level interactions.
