Hope as a Mediator in the Relationship between Gratitude and Life Satisfaction among Science Students
type: item
description: Purpose of the study: This study aimed to examine the effect of gratitude on life satisfaction among students and to investigate whether hope mediates this relationship. The study also sought to clarify the psychological mechanism through which gratitude contributes to life satisfaction. Methodology: This quantitative survey involved 475 science students selected using an accidental sampling technique. Data were collected using the Gratitude Questionnaire-6 (GQ-6), Snyder's Hope Scale (SHS), and the Satisfaction with Life Scale (SWLS). Mediation analysis with 5,000 bootstrap resamples was performed using Jamovi version 2.6. Main Findings: These findings suggest that efforts to improve adolescent life satisfaction need to consider developing hope in addition to gratitude. The findings showed that hope significantly mediated the relationship between gratitude and life satisfaction. The indirect effect of gratitude on life satisfaction through hope was significant (β = 0.28379, p < 0.001), whereas the direct effect became non-significant after hope was included in the model (β = −0.00332, p = 0.955), indicating full mediation. These findings suggest that gratitude contributes to students' life satisfaction primarily by strengthening hope. Novelty/Originality of this study: This study provides empirical evidence that hope functions as a full mediator in the relationship between gratitude and life satisfaction among students. The findings extend the application of Hope Theory by clarifying the psychological mechanism through which gratitude enhances life satisfaction and provide practical implications for developing interventions that integrate gratitude and hope to promote students' psychological well-being.

Problem-Based Learning Enhances Mathematics Engagement: A Multivariate Examination of Motivation and Interest
type: item
description: Purpose of the study: Mathematics learning requires instructional approaches that improve not only cognitive achievement but also affective aspects, particularly students' motivation and interest. This study aimed to examine the effects of PBL on mathematics learning motivation, learning interest, and both variables simultaneously. Methodology: A quantitative quasi-experimental study employing a nonequivalent control group pretest-posttest design was conducted with 71 tenth-grade students selected through cluster random sampling. The experimental group received PBL, while the control group received conventional instruction. Data were collected using the Mathematics Motivation Questionnaire (16 items) and the Interest in Mathematics Questionnaire (20 items) and analyzed using descriptive statistics and Multivariate Analysis of Variance (MANOVA). Main Findings: The results showed that PBL significantly improved mathematics learning motivation (Partial Eta Squared = 0.761) and learning interest (Partial Eta Squared = 0.581). MANOVA further confirmed a significant simultaneous effect of PBL on both affective variables (Wilks’ Lambda = 0.216, p < 0.001). These findings indicate that authentic problem solving, collaboration, and active learning in PBL foster multiple affective outcomes simultaneously. Novelty/Originality of this study: The novelty of this study lies in the simultaneous examination of mathematics learning motivation and interest using MANOVA while positioning student engagement as the conceptual mechanism underlying PBL effectiveness. The findings provide empirical support for implementing PBL as a student-centered approach to strengthen affective outcomes in mathematics education and offer a foundation for future studies using Structural Equation Modeling (SEM) to examine the underlying mechanisms.

type: item
description: Purpose of the study: This study aims to test the antibacterial activity of endophytic bacterial isolates from sungkai leaves against the two test bacteria as antidiarrheal probiotic candidates. Methodology: The research stages included isolation, morphological characterization, Gram staining, motility testing, catalase testing, and antibacterial activity testing using the well diffusion method. Data were analyzed using Shapiro-Wilk, ANOVA, and Tukey's advanced test. Main Findings: The results of the study obtained five isolates (S-1, S-2, S-3, S-4, S-5) with Gram-positive characteristics, bacilli, and positive in motility and catalase tests. Isolates S-1 and S-2 did not have antibacterial activity. In contrast, isolates S-3, S-4, and S-5 were able to inhibit the test bacteria with moderate to strong categories. The highest activity against Escherichia coli was shown by isolate S-3 (10.3 mm), while against Staphylococcus aureus by isolate S-4 (12.08 mm). Statistical analysis showed a significant difference in antibacterial activity between treatments (p<0.001). It was concluded that isolates S-3 and S-4 have the most potential to be developed as antidiarrheal probiotic candidates and natural antibacterial sources. Novelty/Originality of this study: The originality of this study lies in integrating endophytic bacterial exploration from Peronema canescens leaves with antibacterial screening against Escherichia coli and Staphylococcus aureus to identify potential probiotic candidates for antidiarrheal applications.

Enabling Factor Dominance in Women Farmer Group Participation: Time Availability and Production Resource Access
type: item
description: Purpose of the study: This study analyzed the simultaneous and partial influences of seven internal and external factors: age, education level, motivation, time availability, family support, access to production resources, and group management. Methodology: A census-based quantitative survey enrolled all 40 KWT members as respondents. Structured Likert-scale (1–5) questionnaires were administered and validated through item-total correlation analysis (r-critical = 0.312) and Cronbach's alpha reliability testing (α = 0.897). Ordinal data were transformed to an interval scale using the Method of Successive Intervals (MSI). Data were analyzed using multiple linear regression in SPSS v.25, preceded by normality (Kolmogorov–Smirnov), multicollinearity (VIF), heteroscedasticity (Glejser), and autocorrelation (Durbin–Watson) assumption tests at α = 0.05. Main Findings: All seven variables simultaneously and significantly influenced member participation (F = 11.002; p = 0.000; R² = 70.6%). Partial analysis confirmed that only time availability (β = 0.361; p = 0.005) and production resource access (β = 0.430; p = 0.007) were significant predictors, with production resource access being the strongest. Age, education level, motivation, family support, and group management showed no significant partial effects, with group management exhibiting a negative coefficient attributable to the free-rider effect. Novelty/Originality of this study: This study empirically demonstrates that enabling factors, time availability, and access to production resources dominate psychological, demographic, and managerial factors in determining actual KWT member participation. It simultaneously tests seven internal and external variables in a food-production-based empowerment context, reveals the intention-behavior gap mechanism, and proposes a structural-barrier-reduction framework for empowering agricultural women’s groups.

Effectiveness of Reverse Engineering STEM-ESD on Students’ Creative Problem-Solving Ability: A Quasi-Experimental SDG-12 Topic Study
type: item
description: Purpose of the study: This study examines the effectiveness of a Reverse Engineering-based STEM-Education for Sustainable Development (STEM-ESD) learning model in improving tenth-grade students’ Creative Problem Solving (CPS) Thinking ability on the SDG-12 topic, compared with an Engineering Design Process-based STEM-ESD (STEM-EDP) model and conventional instruction. Methodology: A mixed-methods explanatory sequential design combined a quasi-experimental non-equivalent control-group pretest–posttest design with 108 tenth-grade students in three intact classes (STEM-RE, STEM-EDP, and Control) at a public senior high school in Bandung, purposively selected at the class level, and semi-structured interviews with 9 purposively selected students. Quantitative data were analyzed using normalized gain (N-Gain), the Shapiro–Wilk normality test, the Kruskal–Wallis test, and the Mann–Whitney post hoc test with Bonferroni correction in SPSS; qualitative data were analyzed using Braun and Clarke’s thematic analysis. Main Findings: The STEM-RE group achieved the most consistent improvement in CPS Thinking across all four indicators (N-Gain = 0.255–0.301), with statistically significant differences among the three groups (Kruskal-Wallis and Mann-Whitney, p < 0.05). Idea flexibility was the only indicator to reach the moderate category, while the STEM-EDP group showed fluctuating, low-category gains and the Control group showed negligible or negative change. Novelty/Originality of this study: This study provides indicator-level comparative evidence that a Reverse Engineering-based STEM-ESD sequence, contextually integrated with SDG-12, produces more consistent CPS Thinking gains than an Engineering Design Process-based alternative within the same sustainability context a comparison not previously reported thereby advancing both creative problem-solving pedagogy and sustainability-oriented science education.

Analysis of the TDS Sensor Reading Accuracy Between Arduino Uno and ESP32 Microcontrollers for Water Clarity Measurement
type: item
description: Purpose of the study: This study aims to evaluate and compare the reading accuracy of a TDS sensor when interfaced with Arduino UNO and ESP32 microcontrollers, specifically in the context of water clarity measurement applications, by assessing voltage reading precision, data acquisition stability, and measurement consistency across varying dissolved solids concentrations. Methodology: Hardware used includes a TDS sensor, Arduino UNO (ATmega328P, 10-bit ADC), ESP32 NodeMCU (12-bit ADC), and a calibrated TDS meter as the reference instrument. The study employs the Waterfall methodology with direct laboratory observation, potentiometer testing, and voltage measurement across water samples at concentrations of 101, 201, 300, 406, and 515 PPM, each repeated three times at room temperature (~20–21°C). Main Findings: Arduino UNO demonstrated superior accuracy with average voltage errors ranging from 0.21% to 2.12% across all TDS concentrations, compared to ESP32's errors of 13.1% to 54.32%. The ESP32 critically misread a 101 PPM water sample as 48 PPM, yielding a 54.32% error — a failure that would result in a misclassification of water clarity category. Arduino UNO's standard deviation was 0.064 ADC versus ESP32's 2.019 ADC, confirming 31.5 times greater measurement stability. Novelty/Originality of this study: This study offers a direct, multi-parameter comparison of Arduino UNO and ESP32 specifically for TDS-based water clarity measurement, exposing a critical non-linearity flaw in the ESP32's ADC performance at low-voltage ranges (<10% Vref) that has not been previously documented in this application context.

STEM-ESD Learning Based on Engineering Design Process and Reverse Engineering Toward Student Action on SDG-6
type: item
description: Purpose of the study: This study aims to analyze the effect of STEM-ESD learning—implemented through two engineering approaches, Engineering Design Process (EDP) and Reverse Engineering (RE)—on student action competency related to SDG-6 (clean water and sanitation) among secondary school students. Methodology: Mixed-methods convergent design. Participants: 108 students in three groups (two experimental: EDP and RE; one control; 36 per group). Instruments: action questionnaire, student worksheets, open-ended questionnaires, structured interviews. Analysis: descriptive statistics, Shapiro-Wilk normality test, Levene homogeneity test, one-way ANOVA, Kruskal-Wallis test. Main Findings: Neither EDP nor RE produced a statistically significant overall improvement in student action compared to the control group. However, at the indicator level: the RE group showed significant gains in competency achievement; the EDP group consistently outperformed others on current action and future action indicators. Both approaches demonstrate distinct, complementary mechanisms of influence. Novelty/Originality of this study: This study uniquely integrates STEM-ESD with two contrasting engineering approaches (EDP and RE) to address SDG-6, revealing their differential effects on student action competency. It advances knowledge by demonstrating that EDP and RE are not interchangeable but serve complementary functions—RE builds conceptual competence while EDP fosters action orientation and behavioral commitment.

type: item
description: Purpose of the study: The study aims to determine empirical conversion coefficients between compressive strength (f'c) and flexural strength (fs) for a 20 MPa rigid pavement concrete design and to evaluate the specific effects of local South Sumatra aggregates combined with three distinct regional cement brands. Methodology: Laboratory experimental methods utilized 18 specimens (9 cylinders, 9 beams). Aggregates underwent sieve analysis, specific gravity testing, and moisture testing in accordance with SNI standards. Mechanical tests used a compressive strength machine and a two-point loading flexural apparatus. Materials comprised Musi River sand, Baturaja gravel, and Baturaja, Tiga Roda, and Dynamix cements. Data analysis used linear regression models. Main Findings: All variations exceeded the 20 MPa design target. Dynamix cement achieved the highest mean compressive strength (26.23 MPa), while Baturaja cement produced the highest mean flexural strength (3.22 MPa). The derived empirical conversion coefficients (fs √f’c) were 0.67 for Baturaja, 0.66 for Tiga Roda, and 0.62 for Dynamix. The collective correlation yielded a linear regression equation of y = 0.0219x + 2.6131 with R² = 0.2731. Novelty/Originality of this study: This study establishes unique, brand-specific empirical conversion factors for pavement concrete formulated with unique South Sumatra regional aggregates. It directly advances existing engineering knowledge by demonstrating how localized combinations of raw materials deviate from generalized national standard formulas, enabling field engineers to confidently perform rapid quality control without resource-intensive on-site beam trial mixes.

Mapping Students’ Misconceptions in Momentum and Impulse: A Systematic Literature Review of Conceptual Understanding and Instructional Interventions
type: item
description: Purpose of the study: This study aims to identify and analyze students’ misconceptions regarding momentum and impulse through a Systematic Literature Review (SLR), focusing on patterns of misconceptions, difficulties in conceptual understanding, and effective instructional interventions reported in previous studies. Methodology: This study employed a PRISMA-based Systematic Literature Review design. Articles were collected from Scopus-indexed journals, SINTA-accredited journals, ERIC, Taylor & Francis, ResearchGate, and Google Scholar published between 2018 and 2025. The article selection process used purposive sampling based on predefined inclusion and exclusion criteria. From 1,032 identified articles, 8 eligible studies were selected for analysis. Data were collected through document analysis and analyzed using thematic analysis and narrative synthesis. Main Findings: The findings indicate that students’ conceptual understanding of momentum and impulse remains low, while misconceptions persist in force–time–impulse relationships, graphical interpretation, momentum conservation, and momentum–energy integration. Most misconceptions originate from an incomplete understanding of Newtonian mechanics and fragmented conceptual structures. Several instructional approaches, including multiple representations, knowledge integration, cognitive conflict, conceptual change text, and demonstration-based learning, were found effective in reducing misconceptions and improving conceptual understanding. Novelty/Originality of this study: This study provides a focused synthesis of misconception patterns specifically in momentum and impulse topics and emphasizes the importance of conceptual integration-based instruction in reducing persistent misconceptions in physics learning.

Beyond Mean Comparison: Assessing the Proportional Diostribution of Critical Thinking Mastery in Problem Based Learning on Pressure Concepts Using Chi-Square Analysis
type: item
description: Purpose of the study: The study evaluates the effectiveness of Problem-Based Learning (PBL) in improving students’ critical thinking mastery of pressure concepts by analyzing the proportional distribution of mastery rather than relying solely on mean score comparisons. Methodology: A quasi-experimental pretest-posttest nonequivalent control group design was employed with 60 eighth-grade students selected through purposive sampling from intact classes. Students were assigned to a PBL group (n=30) or a conventional instruction group (n=30). Critical thinking was measured using a validated 10-item multiple-choice test adapted from Ennis’s indicators. Baseline equivalence was tested with the Mann–Whitney U test, within-group mastery shifts with McNemar’s test, and between-group distributional differences with the Chi-square test of independence. Reliability was confirmed (Cronbach’s α = 0.86). Main Findings: The PBL group achieved a significantly higher mastery rate (83%) compared to the conventional group (60%), χ²(1) = 4.02, p = 0.045, with a moderate effect size (Cramer’s V = 0.26). McNemar’s test confirmed a statistically significant mastery transition within the PBL class (p < 0.05). The strongest gains occurred in analytical explanation and inferential reasoning dimensions. Novelty/Originality of this study: Analyzing mastery distribution reveals equitable learning outcomes that mean comparisons obscure. The findings demonstrate that PBL systematically shifts categorical achievement toward competency thresholds, particularly in higher-order cognitive dimensions. In practice, this supports the adoption of distributional analysis in classroom assessment. The study’s novelty lies in its methodological shift from continuous mean scoring to categorical mastery distribution, offering a more pedagogically relevant framework for evaluating instructional equity.
