Abstract

Fruit flies (Bactrocera spp.) are important pests of fruit crops that cause serious yield losses. Therefore, environmentally friendly control methods are needed to reduce reliance on synthetic insecticides. This study aimed to evaluate the effects of ethanol extracts of basil leaves (Ocimum basilicum), nutmeg seeds (Myristica fragrans), and their combination on the number of fruit flies captured. The experiment was conducted in a guava orchard in Lembar District, West Lombok. A completely randomized design was employed using three extract treatments (basil leaf extract, nutmeg seed extract, and their combination) at concentrations of 15%, 20%, and 25%, with water as the control. Fruit fly traps were installed for nine days with three replications. Data were analyzed using two-way analysis of variance (ANOVA), followed by the Honestly Significant Difference (HSD) test. The ANOVA results indicated that traps containing plant extracts captured significantly more fruit flies than the control (p < 0.05). However, the HSD test revealed no significant differences among the three extract types or among the concentrations tested (15%, 20%, and 25%) (p > 0.05). These findings indicate that all tested plant extract formulations were similarly effective in attracting fruit flies and performed better than the control, suggesting their potential as environmentally friendly plant-based attractants for fruit fly management.

Abstract

Commercial facial cleansers generally use synthetic surfactants such as SLS, which can potentially irritate the skin and damage the skin barrier if used in excessive concentrations and for long periods. This study aims to produce a facial bar soap formulation based on soapberry (Sapindus rarak DC.) and aloe vera (Aloe vera L.) extracts with the best quality, and to analyze its quality characteristics based on SNI 3532:2021. The study used a descriptive quantitative laboratory experiment method with three formulations, namely F0 (control without extract), F1 (5% soapberry extract and 8% aloe vera extract), and F2 (10% soapberry extract and 8% aloe vera extract), which were made using the cold process method. The parameters tested included pH, foam stability, organoleptic, moisture, and antibacterial activity against Staphylococcus aureus. The results showed that all three formulas met the pH and foam stability requirements of SNI 3532:2021. F1 obtained the highest organoleptic value (4.33) and the most standard pH (9.36), while F2 excelled in foam stability (70.00%), increased skin moisture (53.75%), and antibacterial activity with a strong inhibition zone (11.43 mm). The diameter of the inhibition zone increased with increasing concentration of soapberry extract, from moderate (F0) to strong (F1 and F2). Overall, F2 can be considered as the best quality formulation because it excels in three of the five test parameters. The addition of soapberry and aloe vera extracts has been proven to improve the physical and functional quality of bar facial soap compared to the control formula, so it has the potential to be developed as a natural active ingredient in facial soap preparations.

Abstract

Fatumuti Village, Noemuti Subdistrict, North Central Timor Regency, is served by one primary health center covering 12 villages. Most residents work in agriculture, increasing the risk of open wounds and encouraging the continued use of medicinal plants. Although ethnomedicinal studies on wound treatment have been conducted in other regions of Indonesia, this practice has never been scientifically documented in Fatumuti Village.  This study aimed to document the ethnomedicinal practices used by the Fatumuti Village community for treating open wounds, including medicinal plant diversity, plant parts used, and methods of preparation and application. Methods. A qualitative descriptive design with purposive sampling was employed. Data were collected through in-depth interviews, observation, and documentation involving 3 key informants and 27 triangulation informants from March to May 2026. Data were analyzed using the Miles and Huberman interactive model. Nineteen medicinal plant species from 13 families were identified. Leaves were the most frequently used plant part (13 species). Preparation methods included squeezing, pounding, chewing with rice, extracting sap, grating, and oil preparation, while remedies were applied topically one to three times daily, either singly or in combination. This study provides the first scientific documentation of medicinal plants used for open wound treatment in Fatumuti Village and offers baseline data for future pharmacological research and preservation of local ethnomedicinal knowledge.

Abstract

Oily and acne-prone skin are common skin problems caused by excess sebum production by the sebaceous glands. Betel leaves (Piper betle L.) contain bioactive compounds such as tannins, flavonoids, phenols, and hydroxychavicol, which have the potential to help control sebum levels through astringent, antioxidant, and antibacterial activities. This study aimed to formulate a betel leaf extract toner, determine the physical characteristics of the preparation, and analyze its effectiveness in reducing sebum levels in acne-prone facial skin. This experimental study used two formulas: Formula 1 (F1) with a 3% extract concentration and Formula 2 (F2) with a 5% concentration. These formulas were tested on 20 respondents (10 per group) for seven days. Evaluation included organoleptic tests, homogeneity, pH, viscosity, irritation, and sebum level measurements using a skin analyzer before and after treatment. Data were analyzed using the Shapiro-Wilk test, Paired Sample t-test, Wilcoxon Signed Ranks Test, and Mann-Whitney U-test. The results showed that both formulas were homogeneous, non-irritating, and had pH (4.91 and 5.16) and viscosity (46.41 and 47.10 cPs) that met the standards for topical preparations. Formula 1 experienced a significant decrease in sebum levels from 51.00 to 45.40 (p = 0.005), while Formula 2 decreased from 51.20 to 48.70 (p = 0.011). However, the Mann-Whitney test showed no significant difference in effectiveness between the two concentrations (p = 0.102). It can be concluded that betel leaf extract toner at concentrations of 3% and 5% is effective in reducing sebum levels, but increasing the extract concentration does not provide a statistically significant difference in effectiveness.

Abstract

Ndusuk leaf (Melastoma malabathricum L.) is a plant containing flavonoid compounds, including quercetin, which has potential as an antioxidant, antibacterial, and antidiarrheal agent. Different types of solvents and extraction methods may affect the quercetin content obtained. This study aimed to determine and compare the quercetin content in aqueous and 95% ethanol extracts of Ndusuk leaves using UV-Vis spectrophotometry. This was a laboratory experimental study. Ndusuk leaf simplicia was extracted using the infusion method with water as the solvent and the maceration method with 95% ethanol. Quercetin content was determined using a UV-Vis spectrophotometer at a maximum wavelength of 361 nm. A quercetin standard curve was prepared at concentrations ranging from 4–12 ppm, yielding a linear regression equation of y = 0.0453x + 0.2356 with R² = 0.9942. The yields of aqueous and 95% ethanol extracts were 6.12% and 10.17%, respectively. The quercetin content in the aqueous extract was 0.84 ± 0.04 mg/g, while in the 95% ethanol extract it was 16.27 ± 0.15 mg/g. The 95% ethanol extract demonstrated significantly higher quercetin content compared to the aqueous extract. The use of 95% ethanol with the maceration method was more effective in extracting quercetin from Ndusuk leaves compared to aqueous extraction using the infusion method.

Abstract

Chronic hypertension frequently has comorbidities, necessitating the use of several drugs (polypharmacy), which raises the possibility of drug interactions. This study aimed to determine the prevalence of polypharmacy, potential drug interactions, and the association between patient characteristics, polypharmacy, and potential drug interactions among hypertensive patients at Bakunase Primary Health Center. 572 hypertensive patients' medical data from January to December 2025 were used in this analytical observational study, which used a retrospective cross-sectional approach. Drugs.com® and Medscape® were used to identify potential drug interactions, and the Chi-square test was used to evaluate the results. According to the findings, 32.3% of patients had polypharmacy and 63.7% of patients had possible drug interactions. While polypharmacy was substantially linked to possible drug interactions (p = 0.001), age was significantly linked to both polypharmacy and potential drug interactions (p = 0.003). We conclude that among hypertension patients, age and polypharmacy are strongly linked to a higher likelihood of possible medication interactions.

Abstract

Antimicrobial resistance, treatment failure, and higher healthcare expenditures are all consequences of inappropriate antibiotic usage, which continues to be a significant public health concern. The goal of the DAGUSIBU (Get, Use, Store, and Dispose of Medicines Properly) campaign is to increase public awareness and encourage sensible medication management. This study described community knowledge regarding the DAGUSIBU program for antibiotic medicines among residents of Penfui Timur Village, Kupang Tengah District, Kupang Regency. A descriptive quantitative study was conducted from March to April 2026 involving 99 respondents selected using cluster sampling. Data were collected using a validated structured questionnaire and analyzed descriptively. Knowledge was classified into good, moderate, and poor categories based on predetermined scoring criteria. Overall knowledge of the DAGUSIBU program and antibiotic use was categorized as moderate, with scores of 66.67% and 69.56%, respectively. The highest score was found in obtaining medicines (74.75%), whereas the lowest was in disposing of medicines (57.37%). Most respondents had a moderate level of knowledge. Community knowledge regarding the DAGUSIBU program was generally moderate. The low score for medicine disposal highlights the need for targeted educational interventions to improve appropriate disposal practices and support rational antibiotic use.

Abstract

Ndusuk leaves (Melastoma malabathricum L.) are traditionally used by the Manggarai community to reduce the fatty appearance of pork dishes, yet the molecular basis of this practice has not been investigated using a GC-MS-based metabolomic approach. This study compared the metabolite profiles of Ndusuk leaf decoctions prepared without and with pork. Dried leaves (35 g) were decocted in 2.5 L of water at 100°C for 30 min under two treatments: leaves only (control) and leaves with 100 g pork (sample), each performed in triplicate (n = 3). Metabolites were analyzed by GC-MS and tentatively identified using the NIST library (similarity index ≥80%). The control contained 118 tentatively identified metabolites, whereas the pork-treated extract contained 126. Boiling with pork increased cis-vaccenic acid (+4.07%) and palmitic acid (+1.92%), while decreasing melezitose (−2.80%) and glycerol (−0.73%). These findings demonstrate that cooking with pork alters the metabolite profile of Ndusuk leaf decoctions without providing evidence of direct fat reduction. The observed metabolite shifts may suggest possible phenolic–lipid interactions, antioxidant-related processes, and Maillard reaction-associated changes; however, these mechanisms require confirmation using targeted metabolomics and authentic standards. This study provides the first metabolomic evidence supporting the traditional culinary use of Ndusuk leaves and establishes a scientific basis for Manggarai pork-cooking practices.

Abstract

The need for new antibacterial medicines derived from natural sources is highlighted by the dangerous bacterium Staphylococcus aureus, which causes a variety of diseases and is increasingly linked to antibiotic resistance. The leaves of Chromolaena odorata (L.) contain a variety of bioactive compounds that may have antibacterial qualities. This study aimed to characterize the metabolite profile of the 95% ethanol extract of C. odorata leaves using gas chromatography–mass spectrometry (GC-MS) and evaluate its antibacterial activity against S. aureus. This true experimental post-test-only control group study was conducted from January to May 2026 using leaves collected from Mata Air Village, Kupang Tengah District, Kupang Regency, East Nusa Tenggara, Indonesia. Antibacterial assays were performed in four replicates using the disk diffusion method at extract concentrations of 5–25%. GC-MS identified 118 compounds, with ethyl palmitate, α-linolenic acid, phytol, stigmasterol, squalene, caryophyllene oxide, and α-muurolol as dominant metabolites that may contribute to the observed antibacterial activity based on previous studies. S. aureus was inhibited by the extract in a concentration-dependent manner; inhibition zones increased from 8.03 ± 0.04 mm (5%) to 11.41 ± 0.13 mm (25%), and there were significant differences between treatments (one-way ANOVA, p < 0.001). This study shows how GC-MS metabolite profiling and antibacterial assessment of the 95% ethanol extract of C. odorata can be combined in a unique way. These results suggest that the extract has antibacterial action against S. aureus and could be a source of natural antibacterial chemicals.

Abstract

Mangrove ecosystems play a crucial role in maintaining the ecological balance of coastal environments by supporting biodiversity and protecting shorelines. This study aimed to identify the species composition and analyze the vegetation structure of mangroves in the Bagek Kembar area, Sekotong, West Lombok, Indonesia. The research was conducted in January - May 2026 using a descriptive-exploratory approach with purposive sampling. Vegetation data were collected from 9 quadrats using line transect and quadrat methods. Data were analyzed using the species diversity index (H′), species evenness index (E), species dominance index (D), and Important Value Index (IVI). A total of 306 individuals belonging to five mangrove species were recorded, namely Avicennia marina, Rhizophora apiculata, R. mucronata, R. stylosa, and Sonneratia alba. The species diversity index (H′) was 1.30, indicating moderate diversity, the species evenness index (E) was 0.80, indicating high evenness, and the species dominance index (D) was 0.30, indicating low dominance. Rhizophora mucronata showed the highest Importance Value Index of 115.86, indicating its dominant ecological role in the mangrove community. These findings indicate that the mangrove vegetation in the Bagek Kembar area is in relatively good condition and highlight the ecological importance of the dominant species as a priority for conservation and sustainable mangrove ecosystem management.
