Abstract

The adsorption of Methylene Blue (MB) dye from aqueous solutions using natural adsorbents derived from Gamalama volcanic soil was investigated in this study. The adsorbent materials were characterized by FTIR, X-ray Diffraction (XRD), and Scanning Electron Microscopy (SEM) analyses, confirming the presence of allophane, halloysite, and kaolinite, which exhibit different morphologies and surface properties. Batch adsorption experiments were conducted to evaluate the effects of pH, contact time, and adsorbent mass on the removal efficiency of Methylene Blue. The results demonstrated that Gamalama volcanic soil adsorbents have a high affinity for Methylene Blue, achieving significant removal rates under optimal conditions. The findings suggest that Gamalama volcanic soil is a promising, low-cost, and environmentally friendly adsorbent for treating dye-contaminated wastewater. This study highlights the potential application of natural volcanic soil as an effective adsorbent in environmental remediation. The optimum MB removal was performed by adsorption condition with pH 6, 20 minutes contact time and 30 mg adsorbent.

Abstract

Onventional teaching media used by teachers in teaching chemical bonding has not been able to facilitate students in understanding the concept of chemical bonding because the media used are still in two-dimensional form. Therefore, it is necessary to develop three-dimensional teaching media capable of visualizing the concept of chemical bonding, one of which is augmented reality (AR). This study aims to determine the validity and practicality of an AR-based chemical bonding module. The research type used is Borg and Gall's development research model, modified into 7 research stages. The research sample consisted of 30 students selected using purposive sampling technique. The results of material, media, and language validation analysis indicate that the developed AR-based module is valid with validity percentages of 96.66%, 81.47%, and 88.33%, respectively. Practicality analysis using a practicality questionnaire shows that the developed AR-based module is practical with a practicality score of 93.88%. Therefore, the AR-based module is highly suitable as an alternative teaching media for the topic of chemical bonding

Abstract

This research aims to profile the active antioxidant compounds from leaf extracts of Buas-buas (Premna serratifolia) growing in Pontianak of West Kalimantan (Indonesia) through a metabolomics approach and their activity as anti-COVID-19 candidates by molecular docking. In this study, P. serratifolia leaves were macerated and fractionated using solvents with different polarities. The extracts were then tested for antioxidant activity using the DPPH method, determined the total phenolic content (TPC), flavonoids (TFC), and steroids (TSC), and analyzed antioxidant the functional groups and compounds by Fourier Transform Infrared spectroscopy (FTIR) and Ultra High-Performance Chromatography UHPLC-Q-Orbitrap HRMS. The functional groups on antioxidant activity were determined by Principal Component Analysis (PCA) and Partial Least Square (PLS) regression. Based on a metabolomics approach, the PCA and PLS analysis shows that hydroxyl was the most active antioxidant from P. serratifolia leaves. UHPLC-Q-Orbitrap HRMS analysis showed the presence of scopoletin, esculetin, 7-hydroxycoumarine, matairesinol, hymecromone, and hexylresorcinol in the water fraction of P. serratifolia leaves. Molecular docking with 4YE6, 1OG5, and 3NRZ shows that matairesinol had the most potential as an antioxidant. Mataresinol and hexyresorcinol are phenolic compounds that have great potential as a COVID-19 inhibitor based on molecular docking with 5R81, 7CMD, and 6M2N.

Abstract

Kesum or Polygonum minus (P. minus) is well-known for its high antioxidant content and potential as a therapeutic agent. This study aimed to identify active compounds in P. minus leaf extracts that serve as antioxidants and SARS-CoV-2 inhibitor candidates using metabolomics approach. P. minus leaves were extracted with ethanol and subsequently fractionated using n-hexane, ethyl acetate, and water. The ethyl acetate fraction exhibited the highest antioxidant activity as measured by the DPPH method. Further analysis using UHPLC-Q-Orbitrap HRMS identified several compounds, including 3-hydroxybenzoic acid, quercetin-3betha-D-glucoside, tectoridin, apigenin, hispidulin, and (±)-usnic acid. These compounds were subsequently evaluated in silico by molecular docking against the 1OG5 and 7CMD target proteins. The results demonstrated strong interactions between these compounds and the protein active sites, supporting their potential as both antioxidants and inhibitors of SARS-CoV-2. This study suggests that P. minus is a promising source of bioactive compounds for development in herbal-based therapies in West Kalimantan.
