Abstract

A study was conducted on the effect of oven drying temperature on tannin content of bungur leaves (Lagerstroemia speciosa Auct. non (L.) Pers). Bungur leaves were picked, dry sorted, washed, wet sorted, and drained then oven dried at 30oC, 60(o)C, 90oC respectively. After drying, the samples were then measured for moisture content and then made into bungur leaf powder. Bungur leaf powder was then extracted by modified maceration using aquadem solvent. The extract obtained was tested qualitatively and quantitatively. Qualitative test results showed the presence of tannins. Quantitative tests using permanganometry, obtained tannin levels at drying temperatures of 30oC, 60oC, and 90oC were 7.27% ± 0.1429, 15.26% ± 1.0610, and 9.92% ± 0.7156, respectively. The highest tannin content was obtained at 60oC drying temperature.

Abstract

Background: Dengue infection is an endemic disease in various tropical regions, including Indonesia, with increasing incidence and mortality rates, and currently, no specific therapy is available. One of the potential targets for therapeutic development is the dengue virus (DENV) envelope (E) protein, which plays a crucial role in viral replication in the host. Objective: This study aimed to explore the potential of bioactive compounds from Moringa oleifera leaves as inhibitors of the E protein through an in silico approach using molecular docking methods. Methods: A total of 17 bioactive compounds from Moringa oleifera leaf extract, based on previous studies, were obtained from the PubChem database, while the target protein structure was retrieved from the Protein Data Bank (RCSB). The drug-likeness properties of the compounds were evaluated using the SwissADME web tool. Molecular docking analysis was performed using PyRx Autodock, followed by 3D visualisation and ligand–protein interaction analysis using PyMOL and Discovery Studio 2.0. Apigenin, chrysin, kaempferol, and quercetin exhibited more negative binding affinity values than the control compound Celgosivir (-6.2 kcal/mol), with respective values of -7.4, -7.3, -7.4, and -7.3 Results: kcal/mol. These compounds also shared key amino acid residues with the control at the active site of the envelope protein. Moreover, all four compounds fulfilled the five drug-likeness criteria, indicating good oral bioavailability. Conclusion: Moringa oleifera leaves show potential as candidate anti-dengue agents through inhibition of the DENV envelope protein. Keywords: Moringa oleifera, molecular docking, dengue, antiviral, envelope protein

Abstract

Background: Rabies remains a fatal zoonotic threat in Indonesia, particularly in East Nusa Tenggara (NTT), including Timor Island. Despite national efforts, the disease persists with rising incidence, especially in areas with high dog populations, limited vaccination coverage, and weak cross-sectoral coordination. Objective: This review aims to assess the recent epidemiological trends of rabies in Timor Island and evaluate the effectiveness of One Health implementation in controlling the outbreak. Methods: A literature review was conducted using data from 2010–2025 from sources such as WHO, FAO, Indonesian government agencies, and peer-reviewed journals. Keywords included “rabies,” “One health,” “NTT,” “Timor,” and “epidemiology.” Data were analyzed descriptively and thematically to identify gaps, risks, and strategic responses. Results: Rabies remains endemic in Timor, with more than 50,000 dog bite cases and over 80 human deaths recorded between 2023–2024. Vaccination coverage in dogs remains as low as 17.6%, and there are only 324 vaccinators for the entire province. Social and cultural factors, such as free-roaming dogs and limited public awareness, contribute significantly to transmission. Implementation of One Health remains fragmented, with low community involvement and weak surveillance integration across sectors. Conclusion: A locally adapted One health approach is urgently needed to eliminate rabies in Timor. Strengthening dog vaccination, integrating digital case reporting, engaging traditional leaders, and enforcing village-based regulations are key to effective rabies control. Keywords: Rabies, Timor Island, One health, Dog Vaccination, Community Engagement, Indonesia

Abstract

Helminthiasis remains a significant global public health issue, particularly in tropical and subtropical regions. The extensive and repeated use of synthetic anthelmintic agents, including albendazole and mebendazole, has contributed to the emergence of drug resistance among various parasitic species. Therefore, the exploration of plant-derived compounds with potential anthelmintic activity is urgently needed. This study investigated the potential of bioactive compounds from the stem bark of Faloak (Sterculia quadrifida R. Br) as inhibitors of the Mitochondrial Rhodoquinol-Fumarate Reductase (MRFR) protein through an in silico approach. Five compounds: epicatechin, d-catechin, catechin-(4α→8)-catechin, spinasterol, and spinasterone were analyzed, with Atpeni as the control. Drug-likeness evaluation was conducted using Lipinski’s Rule of Five, while molecular docking, visualization and molecular interaction analysis was performed using PyRx, PyMOL, and Discovery Studio. Four compounds satisfied Lipinski’s criteria, indicating favorable pharmacokinetic properties. Among them, spinasterol and spinasterone demonstrated the strongest binding affinities to MRFR (–10.1 and –9.2 kcal/mol, respectively), exceeding that of the control ligand (–6.4 kcal/mol). Hydrophobic interactions involving key residues such as Leu146, Ala149, and Val153 contributed to complex stability. These results suggest that Faloak stem bark contains promising bioactive compounds that may serve as natural anti-helmintic candidates, warranting further in vitro and in vivo validation

Abstract

Rabies remains a serious zoonotic threat in Indonesia, with thousands of animal bite cases and dozens of human deaths annually. This review article aims to identify the level of community knowledge, attitudes, and practices (KAP) regarding rabies prevention in Indonesia and highlight the importance of a socio-cultural approach in supporting the national rabies elimination program. Data have been collected from scientific articles published between 2015 and 2025. Results indicate that the community’s basic knowledge about rabies is quite high, but there is still a gap between knowledge and actual practice, especially in rural and eastern Indonesia. The involvement of traditional leaders and a One Health approach is recommended to improve the effectiveness of education and compliance with rabies prevention.
