Abstract

Methicillin-resistant Staphylococcus aureus (MRSA) is a major concern in healthcare due to its resistance to antibiotics and ability to form biofilms. This study investigated the antibacterial and antibiofilm activity of the extract and fractions of kelakai (Stenochlaena palustris) leaves against MRSA. Phytochemical screening revealed the presence of alkaloids, flavonoids, steroids, tannins, and triterpenoids in S. palustris leaves. The ethanolic extract of S. palustris leaves exhibited dose-dependent antibacterial activity against MRSA at concentrations up to 500 ppm. Among the fractions, the n-hexane fraction exhibited antibacterial activity at 500 and 1000 ppm, while the methanolic fraction showed inhibition only at 1000 ppm. The ethyl acetate fraction did not show any inhibition. All fractions and extract demonstrated antibiofilm activity, with the n-hexane fraction exhibiting the strongest activity (91.33 ± 1.52%) at 125 ppm. The crude extract of S. palustris leaves showed the weakest antibiofilm activity (32.66 ± 8.14%). These findings suggest that S. palustris leaves contain compounds with antibacterial and antibiofilm properties against MRSA, with the n-hexane fraction being the most promising. Further studies are needed to isolate and characterize the active compounds responsible for these activities.

Abstract

Acute Respiratory Infection (ARI) is an infection that affects the upper and lower respiratory tracts and is commonly caused by viruses or bacteria. This infection frequently occurs in children. One preventive approach to ARI is the implementation of a healthy lifestyle based on herbal practices through the utilization of medicinal plants. The purpose of this community service activity was to improve participants’ knowledge and understanding of ARI and its prevention using medicinal plants at Sentosa Orphanage, Banjarmasin. The activity was conducted through interactive counseling sessions, pre-test and post-test assessments, and question-and-answer discussions. The participants consisted of 30 children from Sentosa Orphanage, Banjarmasin. The activity was carried out smoothly and successfully, with participants showing high enthusiasm and active engagement throughout the program. The results of the pre-test and post-test indicated an improvement in participants’ understanding of herbal-based healthy lifestyle practices that can be applied for the prevention of ARI

Abstract

Acne vulgaris is a common skin disorder influenced by multiple biological factors, including hormonal regulation, microbial activity, and inflammatory processes. The overactivation of androgen-regulated pathways contributes to excessive sebum production, which plays a central role in acne development. Although synthetic anti-acne drugs are widely used, their prolonged application may cause adverse effects, prompting growing interest in natural compounds as alternative therapeutic candidates. Diplazium esculentum, a medicinal fern traditionally used in Indonesia, has been reported to possess antibacterial activity; however, its molecular potential as an anti-acne agent remains insufficiently explored. This study aims to computationally investigate flavonoid compounds derived from Diplazium esculentum as potential anti-acne agents by evaluating their molecular interactions and pharmacokinetic properties. The research focuses on a molecular docking approach combined with pharmacokinetic and toxicity prediction to provide preliminary insights at the molecular level. Flavonoid compounds identified from liquid chromatography–mass spectrometry profiling, including apigenin, genistein, daidzein, and naringenin, were selected as ligands for computational analysis. Molecular docking simulations were performed to predict the interaction between these compounds and the androgen receptor, a key molecular target associated with hormone-regulated sebum production. In addition, pharmacokinetic and toxicity properties were evaluated using in silico absorption, distribution, metabolism, excretion, and toxicity prediction tools to assess drug-likeness and safety profiles. The results demonstrated that all evaluated flavonoids exhibited favorable binding interactions within the ligand-binding domain of the androgen receptor, with interaction patterns comparable to those of a reference compound. Pharmacokinetic predictions indicated acceptable absorption characteristics and low toxicity risk for the selected flavonoids. In conclusion, this computational study highlights the potential of flavonoid compounds from D. esculentum as promising natural candidates for anti-acne applications. The findings support the use of molecular docking and pharmacokinetic prediction as effective preliminary approaches for exploring drug potential and provide a scientific basis for further experimental validation.
