Venni Melinda, Yusi Anggriani, Sondang Khairani, Fitri Nurhayati
Platinum-based chemotherapy remains an important treatment option for patients with advanced non-small cell lung cancer (NSCLC), particularly in settings where reimbursement and resource allocation are major considerations. A retrospective observational cost-effectiveness study was conducted using medical records and billing data from adult patients with NSCLC who received carboplatin–paclitaxel, cisplatin–pemetrexed, or carboplatin–gemcitabine in 2023. Effectiveness outcomes included the one-year survival rate (%) and median progression-free survival (PFS). Costs were calculated based on direct medical expenses over six chemotherapy cycles. Cost-effectiveness was assessed using ACER, ICER, and dominance analysis. A total of 101 patients were included: 81 received carboplatin and paclitaxel, 14 received cisplatin and pemetrexed, and 6 received carboplatin and gemcitabine. Mean direct medical costs were IDR 27, 588, 547, IDR 41, 214, 281, and IDR 47, 471, 752, respectively. No statistically significant differences were observed in one-year survival rate or median PFS among the regimens, although interpretation should consider the unequal sample sizes (81 vs. 14 vs. 6), which limit statistical power. Based on one-year survival, carboplatin–paclitaxel had the lowest ACER and dominated the other regimens by providing higher observed survival at lower cost. Based on median PFS, cisplatin–pemetrexed provided longer PFS than carboplatin–paclitaxel but at a higher cost, requiring ICER-based interpretation. Carboplatin–paclitaxel was associated with the lowest direct medical cost and the most favorable cost-effectiveness profile based on one-year survival among the evaluated regimens. However, conclusions should be interpreted cautiously because of the retrospective design, small and unequal group sizes, and potential confounding by baseline clinical characteristics.

Potential Drug Interactions of Antidiabetic Agents in Geriatric Patients with Type 2 Diabetes Mellitus at the Inpatient Unit of a Hospital in Bandung City
ED. Yunisa Mega Pasha, Lutfiani Az-Zahro, Siti Saidah, Mia Nisrina Anbar Fatin
Type 2 diabetes mellitus is a metabolic disease that commonly occurs in geriatric patients and is generally accompanied by comorbidities. This condition can increase medication use and potentially lead to drug interactions that may affect therapeutic effectiveness and cause adverse effects. This study aimed to identify potential antidiabetic drug interactions and analyze the association between length of hospitalization, number of medications used, and potential drug interactions. This was an analytical observational study with a cross-sectional approach and retrospective data collection using a total sampling technique on 41 medical records of geriatric patients with type 2 diabetes mellitus in the inpatient unit from January to December 2024. Potential drug interactions were identified using Medscape and Drugs. com. with severity levels classified as minor, moderate, and major. The results showed 95 potential antidiabetic drug interactions. Moderate interactions were the most common category, accounting for 88 cases (92.6%), while pharmacodynamic interactions were the most dominant mechanism, with 84 cases (88.4%). Of the 41 patients, 73.2% experienced potential drug interactions. Bivariate analysis using Fisher’s exact test showed a significant association between length of hospitalization, number of medications used, and potential drug interactions (p< 0.05). Potential antidiabetic drug interactions in geriatric patients with type 2 diabetes mellitus may be considered in monitoring medication use, especially in patients with polypharmacy and longer hospital stays. However, this study only evaluated potential drug interactions based on a drug interaction database therefore, further studies are needed to assess the clinical manifestations of drug interactions.

Exploratory Study of Digoxin Safety Based on Pharmacokinetic Approach and Drug Interactions in Patients with Congestive Heart Failure
Nurul Kamilah Sadli, Santi Perawati, Vina Neldi, Novia Tri Astuti, Marizki Pondawinata, Syaza Putri Humaira
Digoxin has a narrow therapeutic index, requiring close monitoring to prevent toxicity, particularly in patients with heart failure, polypharmacy, and impaired renal function. Due to limitations in therapeutic drug monitoring (TDM), we estimated digoxin serum levels using pharmacokinetic formulas based on creatinine clearance. This retrospective observational study aimed to conduct an initial risk screening by estimating digoxin concentrations, evaluating drug interactions, and assessing heart rate in 17 heart failure patients at a regional general hospital in Jambi (January–August 2025). Descriptive analysis revealed that 76% of patients were within the therapeutic range, while 24% exceeded it, with elevated levels correlating with higher creatinine serum and lower creatinine clearance. Common drug interactions involved furosemide, bisoprolol, and proton pump inhibitors, with spironolactone posing a severe risk. Clinically, bisoprolol combined with hypokalemia appeared associated with lower heart rates in patients with predicted toxic concentrations. While the formula-based pharmacokinetic approach serves as a useful exploratory initial screening tool, these findings require further validation through laboratory-based TDM and larger studies.

Athira Prameela, Thenmozhi Krishnasamy
The present research discusses the phytochemical composition, anti-inflammatory, antidiabetic, and antiproliferative efficacy of Vincetoxicum capparidifolium leaf aqueous extract. Phytochemical characterization was performed using FTIR and LC-MS analysis. Network pharmacology was employed to identify potential molecular targets of tylophorine associated with liver associated disorders, followed by molecular docking studies. Anti-inflammatory activity and antidiabetic potential was evaluated in vitro. Cytotoxic outcomes were determined using MTT assay on HepG2 cells, along with AO/EtBr staining and DNA fragmentation analysis. FTIR investigation disclosed the occurrence of various functional groups, incorporating hydroxyl, amine, aromatic, and heteroatom-containing moieties. LC-MS profiling categorized a total of 28 compounds belonging to alkaloids, flavonoids, phenols, and fatty acid derivatives. Network pharmacology analysis identified 94 intersecting targets of tylophorine with liver inflammation, diabetic liver disease, and end-stage liver disease, while molecular docking showed binding affinities of tylophorine with proteins, presenting the strongest interaction with 3HHM (-8.9 kcal mol-1). The extract produced concentration-dependent inhibition of protein denaturation (9.5-68.0%), proteolytic activity (10.3-71.7%), and erythrocyte lysis (10.6-70.2%) although its activity was lower than the reference drug, aspirin. The extract also displayed inhibition of α-amylase and α-glucosidase, with greater potency against α-glucosidase (IC50=99.6 µg mL-1). The cytotoxic activity evaluated using MTT assay supported reduction in HepG2 cell viability (IC50=168 µg mL-1). AO/EtBr staining revealed increased apoptotic features, including membrane damage and nuclear condensation, while DNA fragmentation analysis verified apoptosis-mediated cell death. Overall, V. capparidifolium exhibits notable in vitro anti-inflammatory, antidiabetic, and cytotoxic potential, highlighting its potential as a source of bioactive compounds for further pharmacological investigations.

Microplastic Distribution and Dynamics Between Riparian Vegetation and Alaknanda River in the Himalayan Region
Vaishali Bhatt, Prasant Arya, Jaspal Singh Chauhan
Microplastic (MP) contamination in freshwater ecosystems is an emerging environmental concern, yet interactions between MPs and riparian macrophytes remain poorly understood, particularly in Himalayan river systems. This study provides a baseline assessment of MP surface entanglement across riparian macrophyte species, along with associated surface water and sediment, from River Alaknanda, Srinagar, Uttarakhand, India, sampled in June 2023. A total of 30 macrophyte, surface water, and sediment samples were collected and processed using extraction protocols integrating washing, oxidative digestion, density separation, stereomicroscopic analysis, and polymer characterization through ATR-FTIR spectroscopy. MPs were extensively detected on macrophyte surfaces, with species-specific normalized burdens ranging from 16.47 ± 2.59 to 273.86 ± 26.21 MPs/g dry weight. Kruskal-Wallis analysis revealed significant interspecific variation in normalized MP abundance (H = 25.73, p = 0.0023), with Chenopodium ambrosioides exhibiting significantly higher MP burdens than Conyza sp. and Equisetum sp. No MPs within the analytical detection range of 100 µm-5 mm were detected in digested plant tissues. Fibres were the dominant MP type in macrophytes and water, whereas fragments predominated in sediments, with white particles being most abundant across all matrices. Polymer analysis identified polyester, polyethylene, polypropylene, polyterephthalate, and polyethylene-vinyl acetate as dominant polymers. Strong compositional correlations among macrophytes, water, and sediment indicated similarities in MP characteristics across environmental matrices. These findings suggest riparian macrophytes as complementary matrices for freshwater MP monitoring. Despite methodological and spatial limitations, this study establishes a preliminary framework for incorporating riparian vegetation into freshwater MP monitoring and highlights the need for further investigations.

Traditionally, menginang (a mixture of betel leaf, areca nut, gambir, and lime) has been used as a natural antibacterial agent. This study aimed to compare the antibacterial activity of single betel leaf extract and menginang extract against four oral pathogenic bacteria in vitro. This study compared the antibacterial activity of traditional menginang extract and single betel leaf extract against multiple oral pathogenic bacteria to evaluate their potential synergistic antibacterial effects. The experimental method used a disk diffusion technique at three concentrations (12.5%, 25%, and 50%), and the data were analyzed using one-way ANOVA and Bonferroni post hoc tests. Chlorhexidine 0.2% was used as the positive control, while distilled water was used as the negative control. The 50% menginang extract showed the strongest antibacterial activity against all tested bacteria, with inhibition zones ranging from 22.76 ± 1.38 mm to 28.22 ± 0.14 mm, and the differences were statistically significant (p < 0.05). The inhibition zones produced by the 50% menginang extract were close to those of 0.2% chlorhexidine. The superiority antibacterial activity of menginang extract may be associated with synergistic interactions among alkaloids, phenolics, flavonoids, tannins, saponins, triterpenoids, and steroids identified during phytochemical screening. The menginang extract has high potential to be developed as an innovative natural product for oral health.

Optimization of Extraction Conditions and Kinetics of Antioxidant Compounds from Polyalthia longifolia Leaves
Poro David Clark
This study aimed to optimize phenolic antioxidant extraction from Polyalthia longifolia leaves using hot maceration with 70% ethanol and to characterize the extraction kinetics under optimal conditions. Response surface methodology was used to evaluate the effects of extraction time and temperature on extraction yield, total phenolic content (TPC), and ferric reducing antioxidant power (FRAP). Both factors significantly influenced all responses, with the extraction yield and TPC increasing progressively with temperature and time. FRAP, however, exhibited a dome-shaped response, peaking at intermediate temperatures before declining under prolonged high-temperature conditions, consistent with the thermal degradation of heat-labile antioxidants. The highest phenolic recovery and antioxidant activity were achieved at the upper boundary of the experimental domain, suggesting that the true optimum may lie beyond the conditions tested. Kinetic analysis further revealed that antioxidant-active compounds were mobilized faster than the bulk extractable mass, with implications for reducing extraction time and energy consumption at scale. These findings provide a statistically guided and kinetically informed foundation for the valorization of Polyalthia longifolia leaves, supporting future process optimization across broader solvent systems and extraction techniques for functional food and nutraceutical applications.

Vocational School Students’ Perception of The Potential of Team Game Tournament as A Conventional Learning Strategy
Nadhira Karima, Agus Gozali
The increasing demand for interactive English instruction in vocational schools is often constrained by limited resources and unequal access to digital tools. This study investigated vocational high school students’ perceptions of the Team Game Tournament (TGT) as a conventional non-digital strategy in English instruction. A descriptive quantitative design was used to examine students’ responses after TGT classroom activities. Participants were 32 tenth-grade students in the Fashion Design program at a vocational high school in East Java, Indonesia. Total sampling was applied because all students received the same treatment. Data were collected through a closed-ended questionnaire with 15 items using a four-point Likert scale. The instrument measured perceptions of interest, motivation, vocabulary learning, collaboration, effectiveness, and learning difficulty. Data were analyzed using frequencies, percentages, and mean scores. Findings showed that students generally perceived TGT positively. High mean scores appeared in learning stimulation, teamwork, classroom interest, and overall usefulness. Students reported that TGT encouraged participation, improved collaboration, and made learning more enjoyable. Negative perceptions regarding complexity, time management, competitive pressure, and mismatch with learning preferences were relatively low. A consistency analysis comparing paired positive and negative items indicated coherent response patterns, supporting data credibility. However, results reflect perceptions only and should not be interpreted as direct evidence of effectiveness in real classrooms. These findings suggest that TGT can serve as a low-cost and engaging alternative for vocational English classrooms, particularly in schools with limited digital infrastructure. Future studies should examine long-term effects of TGT on language achievement and motivation across broader contexts.

Stefani Alya Swasa Wuryanto, Ida Ayu Manik Damayanti, Putu Indrayoni
Cutibacterium acnes is a cause of acne. Conventional treatments often lead to side effects and bacterial resistance, necessitating natural alternatives. Globe Amaranth (Gomphrena globosa L. ) shows potential as an anti-acne agent. This study employed an in vitro experimental laboratory design to evaluate the anti-acne activity of G. globosa L. flower extract formulated cream against C. acnes using the well diffusion method. Antibacterial activity was tested using KN (base cream), KP (1% clindamycin cream), F1 (10%), F2 (15%), and F3 (20%), and the data were analyzed using SPSS statistical analysis. Results indicated that the ethanolic extract of GA flowers has an IC50 of 85.483 ppm, TPC of 60.456 ± 0.589 mg GAE/g, and TFC of 34.390 ± 0.989 mg QE/g. It exhibited antibacterial activity against C. acnes, with inhibition zone diameters of 6.693 ± 0.2 mm for the 15% formula and 7.382 ± 0.22 mm for the 20% formula. The antibacterial activity is believed to be driven by the presence of secondary metabolites, particularly phenols and flavonoids identified in the extract.

Nadya Treesna Wulansari, Ni Wayan Kesari Dharmapatni, Ida Ayu Manik Damayanti, Ni Made Raningsih
Buni fruit (Antidesma bunius) is a fruit commonly found in tropical countries such as Indonesia. This fruit has the potential to be developed into kombucha tea because it contains beneficial bioactive compounds. However, the use of buni fruit as kombucha tea remains very limited and has not been studied in depth. The objective of this study was to identify and characterize the volatile compounds in buni fruit kombucha using GC-MS. This study employed a descriptive experimental design to analyze the volatile compounds in buni fruit kombucha after 8 days of fermentation using GC-MS. Buni fruit kombucha fermented for 8 days produced a dark purple color. Based on the analysis of volatile compounds, buni fruit kombucha was identified as containing 30 volatile compounds. The dominant compounds were hexadecanoic acid methyl ester, hexadecanoic acid ethyl ester, 9-octadecenoic acid methyl ester, (E)-9-octadecenoic acid ethyl ester, octadecanoic acid ethyl ester, eicosanoic acid ester, and docosahexaenoic acid methyl ester, which are classified as fatty acid esters and lipids. Additionally, the identified alcohol compounds are patchouli alcohol and 13-tetradecen-11-yn-1-ol. Buni fruit kombucha tea undergoes chemical transformations characterized by the formation of volatile compounds such as esters, alcohols, and fatty acid derivatives as a result of microbial metabolic activity. The profile of the resulting compounds highlights the important role of biotransformation during fermentation in shaping the sensory characteristics and bioactive potential of kombucha tea.
