Abstract

The ancient records about herbal medicine show traditional healing practices are deeply rooted in Indonesian culture. The medical use of plants decreased because of inheritance customs combined with the lack of written documentation on medicinal plants but dependent on oral information transmission. Traditional research and preservation activities of local healing plants which belong to specific cultural communities become possible through this phenomenon. Researchers conducted ethnopharmacological research about antidiarrheal medicinal plant uses that included traditional knowledge about flavonoid-containing plants within the Osing ethnic group of West Java Indonesia. The goal of this research was to verify flavonoid compounds in Osing's medicinal plants through Near Infra-Red (NIR) spectroscopy combined with chemometric methods. The evaluation of antidiarrheal potential for these compounds relied on flavonoid standard reference substances because these compounds demonstrate strong antioxidant properties which stabilize intestinal functioning. Chemometric techniques together with Near Infra-Red spectroscopy (NIR) were applied to analyze krangean leaves (Litsea cubeba) in order to establish their flavonoid compound levels. The quality assessment of multivariate calibration models shows that PLS regression produces RMSEC of 2.870 and RMSEP of 0.0124 with R2cal = 0.9931 and R2val = 0.9919. The analysis using linear discriminant analysis (LDA) succeeded in its completion with recognition rates above 90% for each discriminating class.

Abstract

User satisfaction with pharmaceutical services in healthcare facilities is a critical indicator of service quality and plays an essential role in improving the overall healthcare experience. High satisfaction levels reflect the appropriateness, efficiency, and responsiveness of pharmacy services. This study aimed to evaluate the level of satisfaction among users of pharmaceutical services at the Pharmacy Installation of Clinic X in Jember. This study employed a prospective observational design conducted in August 2025. The study population consisted of outpatients receiving pharmaceutical services, and the sample included patients who met the inclusion criteria and agreed to participate. A total of 160 respondents were selected using consecutive sampling, a non-probability sampling technique. Data were collected using a structured questionnaire and tables documenting respondent characteristics and patient satisfaction outcomes. Satisfaction was assessed across five dimensions of pharmaceutical service quality: reliability, responsiveness, empathy, tangibles, and assurance. Descriptive analysis was used to summarize respondent characteristics and satisfaction scores. Of the 160 respondents, the majority were female (71.25%) and within the age group of 25–44 years (53.75%). Most respondents had a senior high school education or equivalent (50.00%), were self-employed (64.38%), and had visited the clinic twice (38.75%). Satisfaction scores across service dimensions were as follows: reliability 97.1%, responsiveness 65.5%, empathy 68.1%, tangibles 82.1%, and assurance 66.7%. The overall Customer Satisfaction Index (IKM) was 82.2%, categorizing the service quality as good. The results indicate that users were generally satisfied with the pharmaceutical services provided at Clinic X. The high score in the reliability dimension suggests consistent service performance and accuracy. However, the lower scores in responsiveness, assurance, and empathy highlight areas requiring improvement, particularly regarding timely service delivery, confidence-inspiring interactions, and patient-centered communication. Although the overall satisfaction level was good, targeted improvements in these dimensions are essential for enhancing the overall quality of pharmaceutical care. Overall, the level of user satisfaction with pharmaceutical services at Clinic X was categorized as good, with an IKM score of 82.2%. All five dimensions of service quality were rated positively, although responsiveness, assurance, and empathy showed room for improvement. These results highlight the importance of strengthening service quality components beyond technical accuracy to ensure a more holistic and patient-centered pharmaceutical care experience.

Abstract

Indonesia has a long history of using medicinal plants, but much of this knowledge, especially among groups like the Osing people in East Java, is not well-documented. This study looks at the plants used by the Osing community to treat diarrhea. This research was conducted through interviews with residents of Banjar and Licin Villages in Banyuwangi Regency. The significance and perceived efficacy of each medicinal plant were evaluated using the ethnobotanical indices Use Value (UV) and Fidelity Level (FL). They also did tests to find the active chemicals in the plants. The most common plants for treating diarrhea were Psidium guajava (UV = 2.44) and Piper betle (UV = 1.11). Psidium guajava had the highest FL value (64.7%). Tests have shown that these plants contain essential chemicals. Further analysis confirmed the presence of quercetin and kaempferol, which are known to help alleviate stomach problems. To support these findings, computer-based tests were done, including Lipinski rule prediction, ADMET profiling, and molecular docking. The results showed quercetin binds well (ΔG = -9.72) and has a good RMSD value (1.83 Å). This suggests quercetin could be a good starting point for making antidiarrheal drugs. Overall, the study underscores the significance of traditional knowledge and recommends further research on plant-based treatments for stomach issues.

Abstract

Diarrhoea is a widespread gastrointestinal disorder commonly caused by microbial infection, inflammation, or impaired intestinal function. While synthetic antidiarrhoeal drugs are available, their use is often limited by adverse effects and antimicrobial resistance, prompting increasing interest in medicinal plants such as Piper betle (betel leaf). This study systematically reviewed the literature to identify secondary metabolite compounds in Piper betle with antidiarrhoeal potential and to evaluate their biological activities using Radar Chart Analysis (RCA) and Area Under Curve (AUC) methods. A systematic search was performed across PubMed, Scopus, Web of Science, and Google Scholar using predefined keywords. Inclusion criteria comprised studies that investigated Piper betle or its secondary metabolites, reported antidiarrhoeal or related bioactivity, and provided quantitative data suitable for comparison. Studies were excluded if they focused solely on synthetic drugs, were not available in full text, or did not report measurable metabolite data. A total of 35 eligible studies were included after screening 176 records. The findings indicate that flavonoids, polyphenols, tannins, saponins, and catechins in Piper betle contribute to antidiarrhoeal effects through mechanisms that modulate intestinal motility, reduce fluid secretion, activate anti-inflammatory pathways, and exhibit antimicrobial activity. RCA and AUC analyses further demonstrated substantial variability in metabolite composition and antioxidant capacity across studies. Overall, Piper betle exhibits promising therapeutic potential as a natural antidiarrhoeal agent, although further mechanistic and clinical research is warranted.
