Abstract

This study aims to determine potential landslide-prone zones based on the seismic vulnerability index and subsurface lithology derived from electrical rock resistivity values. The research employs the microseismic method and the geoelectric resistivity method with a dipole–dipole configuration. Zones with high landslide susceptibility are identified at points exhibiting high values of the seismic vulnerability index. Based on data acquisition, the highest amplification factor was recorded at point D3 of 9.24, with a corresponding seismic vulnerability index of 24.57. Subsurface lithology analysis reveals an alluvium layer with a thickness of up to 25.00 meters overlying the bedrock. These datasets indicate that the alluvial soil is characterized by soft textures, incomplete consolidation, and low stability levels, rendering these specific points highly vulnerable to significant damage and landslide activity.

Abstract

Anemia during pregnancy remains a significant public health problem, particularly in Indonesia where prevalence exceeds the global average. This study evaluated the effectiveness of a Participatory Learning and Action (PLA) intervention in improving knowledge of iron-deficiency anemia among pregnant women in West Lombok. A quasi-experimental pre–posttest design was conducted with 60 pregnant women divided into intervention and control groups. The intervention involved six PLA sessions focusing on community discussions, nutrition education, and family participation. Knowledge scores were analyzed using paired t-tests and Mann–Whitney U tests, complemented by effect sizes and qualitative thematic analysis. Results showed a substantial improvement in the intervention group, with the proportion of good knowledge increasing from 20.0% to 80.0% and mean scores rising from 11.5 ± 2.5 to 16.8 ± 1.8 (p < 0.001). The control group showed no significant change. Qualitative findings revealed improved spousal support, effective reminder strategies, and increased motivation among health cadres. PLA is an effective and scalable community-based approach for strengthening anemia prevention in maternal health programs.

Abstract

Rapid urbanization and shifting agricultural practices are reshaping watershed sustainability in Indonesia, yet their spatial and hydrological implications in the Rejoso Watershed (East Java) remain insufficiently quantified. This study evaluates land-use/land-cover (LULC) dynamics over 2005–2024 using multi-temporal Landsat imagery from five observation years (2005, 2011, 2015, 2020, and 2024). A hybrid classification (ISODATA clustering combined with visual interpretation) was validated using 250 ground points and confusion matrix metrics (overall accuracy and Kappa). Vegetation declined from 54.72% (197.11 km²) in 2005 to its minimum in 2020 at 38.06% (137.09 km²), then recovered to 41.28% (148.70 km²) in 2024. Agricultural land expanded from 32.14% (115.77 km²) to 52.28% (188.32 km²) in 2020 before contracting to 46.96% (169.14 km²) in 2024, indicating a notable post-2020 trend reversal with vegetation regrowth and reduced cropland extent. Built-up areas increased steadily (4.14% to 7.54%), while open land fluctuated and water bodies remained <1% with a slight decline. The 2020 map achieved the highest accuracy (95.83%; κ=0.96). These findings highlight upstream LULC reconfiguration and continued downstream urbanization, supporting integrated watershed management, upland rehabilitation, and stricter spatial planning.

Abstract

This study aims to identify the water surface profile of the Kali Porong River, analyze changes in riverbed contours at the Kali Porong estuary, and propose appropriate mitigation measures for sediment deposition in the estuarine area. The research methodology involves hydraulic and sediment transport modeling using one-dimensional (1D) and two-dimensional (2D) HEC-RAS, supported by Google Earth image interpretation, cross-section analysis, and riverbed elevation data evaluation. The results indicate significant morphological changes in the Kali Porong River during the period 2013–2023. The upstream and middle reaches tend to experience riverbed degradation due to increased flow energy, while the downstream and estuary segments undergo intensive aggradation, characterized by channel shallowing and delta expansion toward the sea. These riverbed changes directly affect the water surface profile and flow velocity, with the 2023 condition showing relatively higher flow velocities compared to those in 2013. Two-dimensional modeling results suggest that the river system has shifted from a dynamic equilibrium condition toward a morphological imbalance. Based on these findings, mitigation measures are recommended in the form of targeted dredging and the construction of sediment control structures at the estuary to maintain channel stability and reduce long-term sedimentation risks.

Abstract

This study aims to examine the effectiveness of Ethnoscience-Based Student Worksheets (EbSWs) on the subject matter of the nature of physics and the scientific method. The research subjects were 10th-grade students at SMAK Sint Carolus Penfui. This is a descriptive quantitative study using tests to measure cognitive learning outcomes and Science Process Skills (SPS), while questionnaires were used to measure student perceptions (attitudes, skills, and knowledge). The results showed that EbSW were effective in optimizing students' SPS, with an overall average score of 83.90 (very skilled) and a high consistency of results (standard deviation/SD = 3.61). Student perceptions were very positive, with knowledge (average 83.7) and attitude (average 82.1) aspects categorized as very good. SPS perception results (average 77.9) were categorized as good and showed an increase in higher-level cognitive skills. Cognitive learning outcomes showed a level of mastery (mean = 80.67) with a cognitive SD of 19.07, indicating a gap in mastery of the material among students, especially in higher-order thinking skills (HOTS). Overall, EbSW are effective for understanding basic concepts and developing SPS evenly but need to be improved to address varying levels of HOTS mastery.

Abstract

This study examines an expanded Technology Acceptance Model (TAM) to evaluate the implementation of an AI and coding curriculum in high schools. Specifically, it integrates Perceived Usefulness and Perceived Ease of Use into Student Motivation as a mediator to analyze the relationship between Learning Processes and Learning Outcomes, moderated by Prior Coding Experience. Using an explanatory quantitative design, data were collected from 114 students at HelloMotion High School, a benchmarking school for national curriculum piloting. Structural Equation Modeling (SEM-PLS) revealed three critical findings. First, the learning process positively predicts learning outcomes (β = 0.244, p = 0.005). Second, student motivation functions as a significant partial mediator (indirect effect: β = 0.361, p < 0.001, which is stronger than the direct effect), confirming that the direct impact of pedagogy remains significant alongside psychological factors. Third, while the formal moderation of coding experience was statistically nonsignificant (p = 0.321), exploratory multi-group analysis showed that the learning process significantly impacted students with basic experience (p = 0.026) but failed to significantly impact complete novices (p = 0.160). These findings suggest that a "one-size-fits-all" curriculum is insufficient, highlighting the urgency for differentiated instructional strategies to support novice learners in national policy implementation.

Abstract

This study analyzed the relationship between physical activity, diet, and blood sugar levels in patients with diabetes mellitus at the Tambak Wedi Baru Community Health Center, Surabaya, from February to May 2025. The study design used was a correlational analytic design with a cross-sectional approach. The sample consisted of 72 respondents aged 20 to 71 years, who were selected randomly. Univariate analysis focused on a single variable through descriptive statistics, presenting data as numbers, ratios, percentages, or prevalence. Bivariate analysis examined the relationship between two variables using non-parametric statistics, such as the Spearman test, to explore associations between diet, physical activity, and blood sugar levels. Findings revealed significant relationships between physical activity and diet and blood sugar levels (ρ = 0.007; ρ = 0.000). Good physical activity (>1500 MET-min) was associated with normal blood sugar levels, while low physical activity (<600 MET-min) was associated with abnormal blood sugar levels. On the other hand, poor diet (<650 calories) also contributed to high blood sugar levels. This study highlights the importance of multidisciplinary interventions to increase physical activity and healthy eating patterns for the effective management of diabetes mellitus.

Abstract

Polycystic Ovary Syndrome (PCOS) is a highly prevalent endocrine disorder associated with hyperandrogenism, inflammation, and immune system dysfunction. Elevated levels of testosterone are known to affect lymphocyte profiles and contribute to the inflammatory processes in PCOS. The aim of this study was to evaluate the impact of red ginger extract (Zingiber officinale var. rubrum) on lymphocyte subpopulations in a testosterone-induced PCOS rat model. This experimental study involved 30 female Rattus norvegicus divided randomly into five groups: a normal control, a PCOS control (testosterone-induced without treatment), and three PCOS treatment groups receiving different doses of red ginger extract. PCOS induction was done using testosterone propionate. Following the treatment period, lymphocyte subpopulation analysis was performed using flow cytometry based on the CD4⁺, CD8⁺, and CD62L⁺ surface markers. The results indicated significant differences in the expression of CD4⁺, CD8⁺, and CD62L⁺ among all red ginger treatment groups compared to the PCOS control group (p < 0.05), suggesting an immunomodulatory effect of red ginger. In conclusion, the administration of red ginger extract was able to modulate the lymphocyte subpopulation profile in the PCOS model, potentially contributing to controlling immune responses associated with hyperandrogenism.

Abstract

The development of educational technology has encouraged the need for learning innovations that can improve conceptual understanding and student engagement, especially in science subjects in elementary schools. This study aims to analyze the effect of the implementation of interactive media-based deep learning on learning outcomes and student engagement in Grade IV students. The study used a quantitative approach with a one-group pretest–posttest design involving 30 students at MI Muhammadiyah Tahfidzul Qur'an. The instruments consisted of a learning outcome test and an activity observation sheet. Data analysis was carried out using a paired sample t-test and effect size calculation. The results showed a significant increase in learning outcomes, from 64.40 to 77.20 (t = -22.06; p = 0.000), and an increase in student activeness from 60.40 to 78.77 (t = -24.252; p = 0.000). The very large effect size values (d = 4.02 for learning outcomes and d = 4.24 for student activeness) indicate that the learning influence is very strong and practically meaningful. These findings confirm that interactive media-based deep learning is effective in improving academic achievement and active student participation, making it suitable for implementation as a learning strategy in the science subject in elementary schools.

Abstract

Heat-cured acrylic resin dentures are widely used to restore mastication and aesthetics in individuals with tooth loss; however, their surface characteristics may facilitate Candida albicans adhesion, increasing the risk of denture stomatitis. Therefore, effective denture cleansers are required to inhibit fungal colonization. Purple passion fruit (Passiflora edulis Sims) contains bioactive compounds with antifungal potential and may serve as a natural alternative denture cleanser. This study aimed to compare the effectiveness of 15% purple passion fruit peel and pulp extracts with alkaline peroxide in reducing Candida albicans adhesion on heat-cured acrylic resin surfaces. This laboratory experimental study employed a posttest-only control group design using pure Candida albicans isolates. Heat-cured acrylic resin specimens (10 × 10 × 2 mm) were prepared and randomly divided into four groups (n = 6): 15% peel extract, 15% pulp extract, alkaline peroxide (positive control), and distilled water (negative control). All specimens were immersed for 15 minutes in the respective solutions. Fungal adhesion was quantified using a colony counter, and the data were analyzed using the Kruskal–Wallis test followed by the Mann–Whitney post hoc test. The results showed mean colony counts of 832.17 ± 34.79 CFU/mL for the peel extract group, 172.83 ± 35.02 CFU/mL for the pulp extract group, 1,006.50 ± 80.36 CFU/mL for the alkaline peroxide group, and 3,307.33 ± 114.38 CFU/mL for the distilled water group. Statistical analysis revealed significant differences among all groups (p < 0.05). The 15% purple passion fruit pulp extract demonstrated the greatest antifungal effectiveness, which may be attributed to its higher concentration of antifungal phytochemicals compared to the peel extract and the conventional cleanser. In conclusion, both 15% purple passion fruit peel and pulp extracts are more effective than alkaline peroxide in inhibiting Candida albicans adhesion on denture surfaces, with the pulp extract showing the strongest antifungal activity.
