Abstract

Blumea balsamifera (L.) DC. or Sembung is a flowering plant belonging to the genus Blumea of the family Asteraceae. Many pharmacological activities of this plant show potential in human therapy. In this study, an investigation was conducted on the ethanolic extract of B. balsamifera collected from a geothermal area known as Ie-Jue, in Aceh Province, Indonesia. The results showed that the ethanolic extract of B. balsamifera contained secondary metabolites of flavonoids and tannins. Chemical constituents of ethanolic extracts B. balsamifera further analysis using gas chromatography-mass spectrometry (GC-MS) show that active compounds from this plant was Proximadiol (C15H28O2) with relative area 41.76%. This research underscores the compelling potential of the Ie-Jue geothermal area as a promising reservoir of flora owing to the plant's adaptability to geothermal extremities.

Abstract

Bakông Asóe is a typical Acehnese snack loved by older people in Aceh since ancient times. This snack is made from wet tobacco which is used as chewing tobacco. The process of drying Bakông Asóê in the open triggers heavy metal contamination by air pollution from motor vehicles. The process of storing Bakông Asóê in a wet state also triggers the growth of microbes such as bacteria and fungi due to a growth medium in the form of water. The purpose of this study was to determine the content of heavy metal contamination (Pb, Cd, Se, Cu and Hg) and microbiological contamination in the form of bacteria (Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa) and fungi (Candida albicans and Aspergillus niger) in Bakông Asóê which sold on the side of the road without adequate hygiene. The research refers to a qualitative research approach with the type of research that is descriptive research. This study showed that heavy metal exposure in the form of Pb, Cu and Se in the three samples was still in the safe range for consumption. However, exposure to heavy metals in the form of Cd and Hg in the three samples exceeded the consumption standard. The results of the analysis of microbiological contamination in the three Bakông Asóê samples were proven to contain bacterial and fungal contamination, where cocci-shaped bacteria were more commonly found and fungi with the genus Aspergillus sp were also more dominant in the three Bakông Asóê samples. The conclusion of this study is positive for chemical and microbiological contamination in Bakông Asóê, which is sold in Aceh, Ule Kareng and Lambaro Markets.

Abstract

The influence of foreign ions on the response of Al3+ ISE-based polyurethane membranes from castor oil has been determined using SSM. The results showed that the presence of the foreign ions tested did not affect the sensitivity and response of Al3+ ISE. The influence of foreign ions Na+, K+, Li+, Pb2+, Ca2+, Co2+, Cu2+, Ni2+, Cr3+, and Fe3+ on the selectivity of ion-selective electrodes (Al3+ ISE) in the concentration range 1x10-9 – 1x10-4 M has been performed using separate methods. The results show that the presence of foreign ions does not affect the performance of Al3+ ISE with a Kij value < 1. The selectivity sequence of foreign ions is Fe3+ > Cr3+ > Pb2+ > Cu2+ > Ni2+ > Co2+ > Ca2+ > Li+ > Na+ > K+ respectively.

Abstract

Hand hygiene is an important factor that needs to be observed in controlling the spread of diseases transmitted through hand-to-hand contact. Synthesis of silver nanoparticles from tembelekan (Lantana camara) and paku laut (Acrostichum aureum) using the green synthesis method has good antibacterial activity against Staphylococcus aureus and Escherichia coli bacteria. Therefore, a preparation formulation was made, namely hand sanitizer, which is still rarely used. Formulations that have successfully entered the evaluation stage include organoleptic tests, homogeneity tests, spreadability tests, adhesion tests, viscosity tests, pH tests, accelerated stability tests, and irritation tests. Antibacterial activity was evaluated against bacteria Staphylococcus aureus and Escherichia coli. The hand sanitizer is formulated to contain 5% tembelekan AgNPs (F1); paku laut AgNPs 5% (F2); and a combination of 2.5% paku laut AgNPs and 2.5% tembelekan AgNPs. The resulting hand sanitizer has good organoleptic characteristics, except for the color of the preparation, which changed during the accelerated stability test. Test results for pH, adhesion, spreadability, viscosity, and homogeneity of hand sanitizer meet the requirements of a good test. Irritation tests on ten volunteers showed no irritation reaction. Antibacterial tests show that hand sanitizer has bacterial antibacterial activity with an average ± standard deviation of the inhibition zone Staphylococcus aureus is 6.605±0.459(F1); 6.665±0.615(F2); 6.380±0.282(F3) dan Escherichia coli namely 6.575 ± 0.219 (F1); 6.860 ± 0.155 (F2); 6.810 ± 0.056 (F3). Making hand sanitizer AgNPs-based ingredients from plants can be used as hand sanitizer, but stabilizers are required to prevent color changes during storage.

Abstract

The development of selective kinase inhibitors remains a key objective in cancer drug discovery, where predictive computational models can significantly accelerate the identification of leads. In this study, we investigate the fine-tuning strategies of the transformer-based ChemBERTa model for quantitative structure–activity relationship (QSAR) modeling of AXL receptor tyrosine kinase inhibitors, an important therapeutic target implicated in tumor progression and metastasis. A dataset of AXL inhibitors was curated from the ChEMBL database. Three fine-tuning configurations, namely baseline, full fine-tune, and aggressive, were implemented to examine the influence of learning rate, weight decay, and the number of frozen transformer layers on model performance. Models were evaluated using accuracy, precision, recall, F1-score, and calibration metrics. Results showed that both the full fine-tune and aggressive configurations outperformed the baseline model, achieving higher precision and F1-scores while maintaining robust recall. The aggressive configuration achieved the most balanced performance, with improved calibration and the lowest expected calibration error, indicating reliable probabilistic predictions. Overall, this study highlights that controlled fine-tuning of ChemBERTa significantly enhances predictive performance and confidence estimation in QSAR modeling, offering valuable insights for optimizing transformer-based chemical language models in kinase-targeted drug discovery.

Abstract

This study developed a green synthesis approach for silver nanoparticles (AgNPs) using ethanolic extracts of Chromolaena odorata leaves (LCo) collected from geothermal areas, followed by post-synthesis incorporation of patchouli oil (PO) to improve antimicrobial performance. The synthesis was optimized using Response Surface Methodology (RSM) based on AgNO₃ concentration and pH, with surface plasmon resonance (SPR) as the response indicator. Successful formation of AgNPs was confirmed by characteristic SPR absorption in the visible region. Structural and morphological analyses indicated the involvement of plant-derived functional groups in nanoparticle stabilization, with predominantly spherical particles and some aggregation observed. Antimicrobial testing against Staphylococcus aureus, Escherichia coli, and Candida albicans showed that the PO-AgNPs-LCo system exhibited a slightly higher inhibition zone compared to AgNPs-LCo alone, indicating a marginal enhancement in antimicrobial activity. These results suggest that geothermal-derived plant extracts can be effectively utilized for AgNPs synthesis, while post-synthesis incorporation of natural oils may provide additional functional modification. However, the observed enhancement remains limited, indicating the need for further optimization and mechanistic studies. Overall, this work highlights a simple and eco-friendly route for developing plant-based antimicrobial nanomaterials.
