Abstract

Caesalpinia bonduc (L) Roxb is a medicinal plant commonly utilized in traditional Indonesian medicine, particularly for the treatment of diabetes mellitus (DM). This study examined the effects of varying doses C. bonduc extract on fasting blood sugar (FBS), malondialdehyde (MDA), tumor necrosis factor-α (TNF-α), transforming growth factor-β (TGF-β), and pancreatic histology in male and female wistar rats with diabetes. The study design included six groups of 18 male and female rats (Wistar strain) each. To develop diabetes, nicotinamide (NA) (110 mg/kg) and streptozotocin (STZ) (45 mg/kg) were supplied, followed by oral administration of C. bonduc extract at dosages of 200, 400, and 600 mg/kg for 21 days. We utilized ELISA to analyze biochemical parameters and employed H&E staining to evaluate histological changes. A factorial design was employed for the statistical analysis to examine the effects of both dosage and sex. This study offers a unique comparative examination of the antidiabetic efficacy of C. bonduc across genders, a dimension seldom explored in experimental diabetes research. The findings indicated that C. bonduc markedly reduced levels of FBS, MDA, TNF-α, and TGF-β (p < 0.05) enhanced the structural integrity of the pancreas. There were no significant differences between males and female (p > 0.05). The dosage and sex influenced MDA and TGF-β. The extract of C. bonduc shown the ability to lower blood sugar, fight free radicals, and reduce inflammation; however, the intensity of these benefits depended on the dosage given. This means that it might assist persons with diabetes minimize oxidative stress and damage to the pancreas.

Abstract

Landslides are one of the major hazards in volcanic areas, causing loss of life, property damage, and degradation of the environment. The western slopes of Mount Lawu, a stratovolcano in Central Java Province, Indonesia, are especially prone to landslides because of steep topography and increasing human activities. The rapid population growth and land use changes, driven by tourism and agricultural expansion, have increased the vulnerability of the area. This study examines the performance of the weight of evidence (WoE) method in mapping landslide susceptibility over the western slopes of Mount Lawu, with a focus on the interaction between environmental factors and land use. The parameters considered in this research include slope, lithology, distance from lineaments, roads, and rivers, rainfall, and land use. The spatial datasets used included a digital elevation model (DEM) at a scale of 1:16,000, as well as slope, river, lineament, and land-use data at a scale of 1:25,000, and lithology data at a scale of 1:50,000. All of these datasets were processed and analyzed using ArcGIS Pro. The WoE analysis resulted in the landslide susceptibility map, which divided susceptibility into four classes: high, moderate, low, and very low. The model achieved an accuracy of 0.81, demonstrating strong predictive capability. The landslide susceptibility map showed high-risk zones along steep slopes, near rivers, and close to roads, particularly in northern Ngargoyoso and western-southern Tawangmangu Districts. These results highlight the utility of the WoE method for developing the landslide susceptibility map with good accuracy. A landslide susceptibility map can be used to evaluate existing land use and to create spatial planning-based landslide disaster risk reduction.

Abstract

Radicalism remains a critical threat to Indonesia's national security and social cohesion, necessitating urgent efforts to understand and mitigate its spread. This study develops a mathematical model to describe the dynamics of radicalization and deradicalization in Indonesia, using a compartmental structure that divides the population into susceptible, extremist, recruiter, treated, and vaccinated groups. The model incorporates a saturated incidence rate to capture the nonlinear effects of radical interactions. Numerical simulations are carried out using the fifth-order Runge–Kutta method to illustrate the transitions between population groups. The results indicate a significant decline in extremist and recruiter populations, while vaccination against radical ideas contributes to long-term resilience. Sensitivity analysis shows that the radicalization rate and recruitment effectiveness are the most influential parameters driving the spread of radicalism. These findings provide new insights into the mechanisms of radicalization and serve as a foundation for designing evidence-based preventive strategies.

Abstract

Microbial infections pose serious threats to human health, emphasizing the need to develop effective antimicrobial materials. This study aims to synthesize, characterize, and evaluate the antimicrobial properties of ester vanillin-benzoate (1) and its chitosan-based composite material (2). Furthermore, the synthesized compound was tested for antibacterial and antifungal activities against Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa, and Candida albicans using the Kirby-Bauer diffusion method. The synthesized compounds were effective against S. aureus and B. subtilis but had minimal action against P. aeruginosa, E. coli, and C. albicans. The formation of the Schiff-base composite could increase its antibacterial activity, indicating a synergistic effect arising from the combination of compound 1 and chitosan.

Abstract

The growing prevalence of pharmaceutical contaminants, particularly amoxicillin (AMX), in aquatic environments poses serious threats to both ecosystems and public health. Addressing this issue requires the development of efficient photocatalysts capable of degrading such pollutants under visible-light irradiation. This study explores the enhanced photocatalytic degradation of AMX under visible light using copper and nitrogen co-doped titanium dioxide (TiO₂-Cu/N) synthesized utilizing copper recovered from electroplating wastewater. Comprehensive characterization through XRD, UV-Visible DRS, and TEM demonstrated that a Cu doping level of 0.60%, combined with 30% nitrogen co-doping and calcination at 500 °C, resulted in the most significant enhancement in photocatalytic activity under visible-light irradiation, attributed to the most effective bandgap narrowing. Notably, the TiO₂-Cu/N photocatalyst with optimized composition exhibited superior physicochemical properties and photocatalytic performance compared to its singly doped counterparts. The optimal condition of the AMX degradation was achieved using 100 mg of TiO₂-Cu/N to treat 100 mL of a 20 mg/L AMX solution at pH 6 under 2 h of visible-light irradiation, which was 90%. Furthermore, the Cu dopant in the TiO₂-Cu/N matrix remained stable during the photocatalytic process, as evidenced by the sustained activity even after three consecutive cycles. Additionally, the use of radical scavengers confirmed that hydroxyl radicals (•OH) were the predominant reactive species responsible for the degradation of amoxicillin. These findings highlight the promising potential of utilizing industrial wastewater as a dopant source for the sustainable development of high-performance photocatalysts in water treatment applications.

Abstract

Magnetic cleanliness is essential for small satellites carrying sensitive payloads such as magnetometers and particle detectors. Reaction wheel assemblies (RWAs) represent a primary source of stray magnetic fields, requiring effective shielding under strict mass and volume constraints. This study uses three-dimensional finite element analysis (FEM) in ANSYS Maxwell to evaluate the shielding effectiveness (SE) of high-permeability alloys (Mu-metal and Permalloy 80) and low-carbon steels (AISI 1008/1010) at thicknesses of 1–3 mm, with aluminum 6061-T6 as a non-magnetic baseline, within a cylindrical RWA enclosure geometry. Results reveal a critical design trade-off: High-permeability alloys provide superior attenuation (>65 dB at 100 mm; residual field <150 nT) and high mass efficiency (>700 dB/kg) but saturate at low flux density (0.8 T) and are costly. Low-carbon steels offer moderate SE (34–40 dB) with far higher saturation tolerance (2.2 T), structural robustness, and lower cost. Thickness scaling shows diminishing returns beyond 2 mm for high-permeability materials, whereas steels improve more linearly. Rather than proposing a new shielding concept, this study applies an integrated FEM-based evaluation approach for small satellite platforms to consistently assess shielding effectiveness, nonlinear saturation behavior, thickness scaling, and mass efficiency of candidate materials within a reaction-wheel-representative geometry under identical boundary conditions.

Abstract

To understand the environmental distribution of Burkholderia pseudomallei, it is essential to study the causative agent of melioidosis for effective public health risk assessment. This study integrates geostatistical analysis and machine learning to predict the spatial distribution of Burkholderia pseudomallei in paddy soils of northeastern Thailand. A total of 92 soil samples were collected and analysed using culture-based methods. Environmental covariates were derived from remote sensing and topographic data, including land surface temperature, normalised difference salinity index, bare soil index, digital elevation model, distance to water, slope, aspect, and soil drainage. Indicator kriging was used to generate a spatial probability map of Burkholderia pseudomallei presence. An extreme gradient boosting machine learning model was applied to predict bacterial presence. Of the 92 soil samples analysed, 40.22% tested positive for Burkholderia pseudomallei. Indicator kriging demonstrated clustered distributions primarily in low-lying, poorly drained areas. The extreme gradient boosting model achieved an F1-score of 0.70 on the testing dataset. Shapley additive explanations analysis highlighted the digital elevation model, bare soil index, and slope as the most influential predictors. The resulting risk maps provide valuable tools for identifying high-risk areas, supporting targeted surveillance and public health interventions in melioidosis-endemic regions.

Abstract

Plasmodium falciparum caused four million new malaria cases in Southeast Asia in 2023, with heterogeneous transmission patterns and the development of artemisinin resistance. The merozoite surface protein genes (msp-1 and msp-2) serve as genetic markers for analyzing the parasite population structure and multiplicity of infection (MOI). However, a comprehensive synthesis of regional data is limited. This study aimed to determine the genetic diversity and MOI of P. falciparum in Southeast Asia. This systematic review was guided by PRISMA guidelines with searches in the Scopus, PubMed, ProQuest, and Google Scholar databases (2014–2024). The inclusion criterion was observational studies, analyzing the genetic diversity of P. falciparum via msp-1 and msp-2 markers in Southeast Asia. The extracted data included the frequency of msp-1 and msp-2 family alleles, the prevalence of polyclonal infections, and the mean MOI value. Quality assessment was performed via the joanna briggs institute critical appraisal tools with narrative synthesis following the synthesis without meta-analysis (SWiM) guidelines. Fifteen studies; Indonesia (40%), Thailand (26.67%), Myanmar (20%), Vietnam and Malaysia (6.66%) with 1,830 samples successfully genotyped from 2,130 collected samples. The MAD20 (msp-1) allele dominated most locations, with frequencies of up to 100% in Lampung. The distribution of msp-2 alleles showed geographical variation, with FC27 dominating in Papua (96.2%) and 3D7/IC in Vietnam (97.0%). The prevalence of polyclonal infection ranged from 0-84.6%, with MOI values ranging from 1.0-2.93. The hyperendemic areas presented high MOIs (>2.0), whereas the hypoendemic areas presented MOIs close to 1.0, confirming a positive correlation with malaria transmission intensity. The P. falciparum population in Southeast Asia shows high genetic diversity, with geographically variable allele distribution patterns, and MOI values are correlated with malaria endemicity levels. These findings support the need for regional molecular surveillance and a polyvalent approach to the development of msp-based vaccines.

Abstract

Encapsulation technology was developed to address the issues of limited bioavailability and instability associated with black soldier fly oil (BSFO). This research synthesized a nano-emulsion of BSFO utilizing the ultrasonication method, while varying the sources of antioxidants (black seed oil (BSO) and curcumin) and emulsifiers (polyethylene glycol (PEG), whey protein isolate, and Tween 80). The FTIR analysis revealed that the nanoemulsion samples displayed peaks at 3500–3000 cm-1 (O–H stretching), 2900–2700 cm-1 (N–H stretching), and 1700–1500 cm-1 (C=O stretching), suggesting the presence of BSFO, curcumin, BSO, and the characteristics of the emulsifiers. Particle size analysis (PSA) indicated that the emulsion had an average particle size (Z-average) of approximately 229–686 nm. The nan’oemulsion containing PEG showed reduced particle sizes of 218 and 229 nm compared to those with other emulsifiers, attributable to the inherently smaller size of PEG. The HB (BSO with PEG emulsifier) showed a reduced particle size due to the smaller molecular size of the antioxidant BSO compared to curcumin. The polydispersity index (PI) values for HB and CB (curcumin with PEG emulsifier) were 0.3 and 0.2, respectively, indicating relatively homogeneous particles, consistent with the criterion of a PI value below 0.4. Biological assays showed that CB had the highest DPPH inhibition at 83%, while curcumin exhibited 90%, exceeding that of BSO. The inhibition zones of HB are 2.45 cm for Staphylococcus aureus and 2.70 cm for Escherichia coli, representing the highest levels of inhibition. In this study, PEG is the best emulsifier for achieving a smaller nanoemulsion particle size. PEG facilitates the incorporation of BSFO with antioxidants, enhancing stability, efficacy, and bioavailability in various applications, particularly in the medical and food sectors.
