This study was conducted to determine the best log-linear model describing the relationship between gender, sleep duration, extracurricular activities, and student learning outcomes at SMAN 1 Kualuh Hulu. A log-linear analysis approach was used to identify interaction patterns among the variables and evaluate their contribution to student academic performance. The findings showed that the selected model adequately explained the structure of the observed data. A significant three-way interaction was identified between learning outcomes, sleep duration, and gender. The results indicated that insufficient sleep duration had a negative impact on student learning outcomes, and this effect varied by gender. Female students were found to be more vulnerable to decreased academic performance caused by sleep disturbances compared to male students. Meanwhile, extracurricular activities did not demonstrate a significant direct interaction with learning outcomes. This suggests that participation in extracurricular activities was not a major factor influencing differences in academic achievement among students at SMAN 1 Kualuh Hulu.

Dengue remains a major vector-borne disease worldwide, and the increasing resistance of Aedes aegypti to synthetic insecticides has encouraged the exploration of environmentally friendly botanical larvicides. This study aimed to systematically evaluate scientific evidence regarding the larvicidal potential of endemic Kalimantan plants against Aedes aegypti and to identify priority candidates for future research. A systematic literature review was conducted following the PRISMA 2020 guidelines. Literature searches were performed across Scopus, PubMed, ScienceDirect, SpringerLink, Web of Science, MDPI, Wiley Online Library, Garuda, SINTA, and Google Scholar for studies published between January 2016 and January 2026. A total of 925 records were identified, and after duplicate removal, screening, and eligibility assessment, 88 studies were included in the final synthesis. The results showed that botanical larvicides rich in alkaloids, flavonoids, terpenoids, phenolics, limonoids, and sulfur compounds demonstrated significant larvicidal activity against Aedes aegypti. However, no direct larvicidal studies were identified for endemic Kalimantan species, including Fibraurea tinctoria, Arcangelisia flava, Dacrydium beccarii, Agathis borneensis, and Scorodocarpus borneensis. These findings highlight substantial evidence gaps and indicate that Kalimantan biodiversity represents a promising source of novel larvicidal agents for sustainable dengue vector control.

This study aims to analyze students’ mathematical reasoning abilities in quadratic function material through the use of Desmos. The research employed a qualitative descriptive approach using a case study and usability testing method. Data were collected through post-tests and interviews involving students’ responses in solving quadratic function problems. The analysis focused on several indicators of mathematical reasoning, including procedural skills, conceptual understanding, and analytical ability. The results show that students generally demonstrate adequate procedural reasoning, particularly in substitution and computation tasks. They are also able to relate algebraic representations to geometric interpretations, such as determining intercept points and analyzing the direction of parabolas. However, limitations were found in conceptual understanding, especially in identifying graph characteristics without relying on procedural steps. The use of Desmos significantly supports the development of students’ mathematical reasoning by providing real-time visualization, facilitating exploration of function parameters, and enabling verification of results. Overall, Desmos contributes to enhancing procedural, conceptual, and analytical dimensions of mathematical reasoning, although its effectiveness depends on proper instructional design.

This study aims to examine the effects of applying a Problem-Based Learning (PBL) method combined with PhET simulation tools on enhancing critical thinking skills among eighth-grade students at SMP Negeri 4 Singaraja when learning vibration and wave topics. It adopted a quasi-experimental approach with a Pretest-Posttest setup and non-equivalent control group design. The participant cohort comprised 75 students distributed across two groups: the treatment group (n=38) who engaged in learning activities using PBL supplemented by PhET simulation, and the comparison group (n=37) who received PBL instruction without PhET simulation support. Data collection was conducted through essay-type assessment instruments containing 7 questions designed to evaluate critical thinking competencies based on Ennis' theoretical framework. Data processing employed descriptive statistical analysis, N-Gain Score computation and ANCOVA testing were conducted at a 0.05 significance level. Results showed the treatment group's average Posttest score at 84, compared to 66 for the control group. The ANCOVA produced an F-value of 103.701 (p < 0.001), confirming a statistically significant difference in critical thinking skills between the groups. The adjusted mean Posttest scores were 83.99 for the treatment group and 66.01 for the comparison group, reflecting a differential of 17.99 points. Consequently, the findings substantiate that the integration of PBL with PhET simulation demonstrates greater effectiveness in fostering students' critical thinking skills in comparison to conventional PBL implementation without technology-enhanced simulation assistance.

Differential equations involve derivatives of unknown functions and are widely used in mathematical modeling of various real-world problems. They can be classified based on linearity, homogeneity, coefficients, number of independent variables, degree, and order, thus requiring appropriate solution methods. One commonly used approach is the reduction of order method, which simplifies equations by reducing their order step by step. However, this method generally requires the solution of the corresponding homogeneous equation as an initial step. This study aims to solve nonhomogeneous linear ordinary differential equations of order with constant coefficients using the reduction of order method without determining the homogeneous solution. This research is a theoretical study based on relevant references concerning solution methods and types of differential equations. The procedure consists of two main stages: determining the fundamental symmetric polynomial variables based on the coefficients and constructing a sequence of solutions through first-order linear differential equations obtained from the reduction process. The results show that this method systematically produces the general solution of linear differential equations of order , making it an effective and efficient alternative approach

This article examines needs analysis and curriculum analysis as the foundational bases for developing effective teaching materials. Using a library research method, this study reviews various scientific journal articles, reference books, and relevant official documents. Needs analysis is a systematic process conducted to identify the gap between students' current conditions and the competencies they are expected to achieve, serving as the most critical stage in determining the direction of teaching material development. Meanwhile, curriculum analysis is carried out to ensure that the teaching materials developed remain aligned with competency standards, learning outcomes, content structure, and applicable educational policies. The integration of both analyses produces teaching materials that are not only contextually relevant to students' real conditions but also consistent with curriculum demands. Systematic steps in this integration including learner characteristic analysis, curriculum document review, material priority mapping, and authentic assessment design significantly contribute to improving the quality, effectiveness, and meaningfulness of learning. This article concludes that needs analysis and curriculum analysis are inseparable and must be conducted systematically before the development of teaching materials begins.

This research is driven by the significance of examining language meaning, particularly connotative meaning which is often used to convey implicit messages in literary works. Folktales, as one type of oral literature, often utilize character names that carry specific meanings, such as Malin Kundang from Minangkabau. The aim of this research is to uncover the connotative meaning of the character name “Malin Kundang”, as well as its relationship with the moral and cultural values of the society. The methodology involves qualitative research using semantic analysis and a descriptive approach. Data were collected from the Malin Kundang folktale text thru library study and documentation techniques. Next, the processes of identification, classification, and interpretation of meaning were done in order to examine the data. The research result show that denotatively, the name Malin Kundang only functions as the identity of the character, but connotatively, it functions as a symbol of a disobedient child who does not respect their parents. The meaning is formed from the plot of the story and reinforced by the Minangkabau cultural values that uphold respect for parents. The implications of this research indicate that the naming of characters in folklore is not only linguistic but also reflects the moral and cultural values inherited by society.

This study analyzes how Abuela Alma Madrigal's behaviors toward her family in Disney's Encanto (2021) are influenced by Jungian archetypes. The psychological analysis of matriarchal characters in animated films has received little attention, despite the widespread usage of Jungian theory in film analysis. The aim of this study is to identify the Jungian archetypes that Abuela embodies and analyze how they influence her relationships with the Madrigal family. Data was gathered by repeatedly watching the movie using a qualitative, descriptive approach. Jung's archetypal theory (1959) served as the main framework for the analysis of a selection of dialogues that were transcribed and classified based on specific archetypes. The results show that Abuela's behavior is greatly influenced by five archetypes. She is motivated by the persona archetype to maintain a public persona of magical perfection, valuing each family member according to how they contribute to this image. The trauma of losing her husband Pedro is the source of the Shadow archetype, which takes the form of denial and blame projection until Mirabel confronts it. The Great Mother archetype illustrates how her parental love turned into conditional acceptance and overprotection. The Wise Old Woman archetype highlights the difference between her appearance of authority and the personal doubt she carries. Finally, the Self archetype signifies her psychological transformation as she completely accepts the value of each family member and integrates her suppressed fears, completing Jung's individuation process. These results validate that Jungian theory provides a useful framework for analyzing matriarchal characters in animated films and show how universal psychological patterns associated with trauma, authority, and family dynamics can be meaningfully reflected in modern animated films.

Background: Automatic segmentation of the thyroid gland in ultrasonography (USG) images using deep learning requires a user-friendly interface to support diagnostic and educational processes. Purpose: This study aims to develop and implement a Graphical User Interface (GUI) that integrates a deep learning U-Net model for interactive and efficient segmentation and visualization of thyroid USG images. Method: The development method employed the Rapid Application Development (RAD) approach using MATLAB programming language. The GUI is designed to load transverse and sagittal USG images, display automatic segmentation results, and calculate thyroid gland volume based on dimensions measured automatically from the segmentation output. Testing was conducted using USG image data from 15 volunteers, and GUI functionality was evaluated using black box testing. Result: The GUI successfully displayed USG images and segmentation results with a responsive 4-panel interface; zoom, pan, and image navigation features functioned well. Automatic segmentation occurred in real-time after image input, and volume measurement results appeared automatically. Black box testing evaluation showed all GUI features operated as expected. The average Dice Similarity Coefficient (DSC) of 0.91 indicates high performance of the U-Net model in thyroid segmentation, consistent with previous findings. Statistical testing confirmed no significant difference between volume measurements using the application and manual methods (p = 0.953). Conclusion: This GUI implementation facilitates users in performing deep learning-based segmentation and visualization of thyroid USG images, improving efficiency and accuracy in thyroid volume measurement. The GUI has potential applications in clinical practice and radiology education.

Preeclampsia remains a major contributor to maternal morbidity and mortality, particularly in developing countries such as Indonesia. Early detection and integrated management at the primary healthcare level are essential to prevent disease progression and improve maternal outcomes.  Modifiable risk factors such as maternal obesity, inadequate calcium intake, and poor clinical management contribute significantly to disease progression (WHO, 2021; Zhang et al., 2020). This study aimed to evaluate the effectiveness of an Integrated Maternal Health Model (IMHM) combining risk assessment, nutritional intervention, and clinical management for early prevention and control of preeclampsia in primary healthcare settings. A quasi-experimental cohort study was conducted among 104 pregnant women, consisting of 52 preeclamptic and 52 normotensive participants in community health centers in Medan, Indonesia. Data were collected across four antenatal visits, including blood pressure measurements, proteinuria (dipstick), calcium intake, supplementation adherence, and antihypertensive therapy. Statistical analyses included bivariate and longitudinal tests. The results showed that maternal obesity, history of preeclampsia, and hypertension were significant risk factors. Adequate calcium intake demonstrated a protective effect against preeclampsia (p < 0.05), consistent with recent evidence indicating that calcium supplementation can reduce the risk of preeclampsia by up to 49%. However, calcium supplementation did not significantly influence blood pressure among normotensive pregnant women. Antihypertensive therapy, particularly intensive nifedipine regimens, showed significant differences in blood pressure patterns across visits (p < 0.05). In addition, proteinuria levels significantly decreased over time (p < 0.001), indicating improvement in renal function. In conclusion, the IMHM is effective in improving maternal outcomes through a multi-component approach integrating clinical, nutritional, and monitoring strategies. This model provides a practical and scalable framework for early prevention and management of preeclampsia in primary healthcare settings.

This quantitative study examines the influence of information quality, work engagement, and leadership style on decision making effectiveness among employees of a manufacturing company. Data were collected from 100 respondents using accidental sampling technique. Multiple linear regression analysis revealed that all three independent variables simultaneously affect decision making effectiveness. Partially, information quality, work engagement, and leadership style each have significant positive effects on decision making effectiveness. Leadership style demonstrates the strongest influence, followed by information quality and work engagement. The regression equation indicates positive contributions from all predictors. The coefficient of determination shows that the three predictors collectively explain a substantial portion of variance in decision making effectiveness. Findings suggest manufacturing companies should prioritize transformational leadership development programs, conduct information system audits, and implement work engagement initiatives to enhance decision making effectiveness. Future research should expand to other industries, add organizational culture variables, and employ longitudinal designs.

Stock market volatility represents a key indicator of financial market uncertainty, particularly in emerging economies where market structures are still evolving and are highly sensitive to global shocks. This study aims to analyze and compare the volatility dynamics of stock markets in four Asian emerging economies: Indonesia, India, Malaysia, and Thailand. The research employs a quantitative approach using daily stock index data from January 2011 to January 2026 obtained from Yahoo Finance. Stock returns are calculated using logarithmic transformation and analyzed using the Generalized Autoregressive Conditional Heteroskedasticity (GARCH(1,1)) model. Prior to model estimation, stationarity and ARCH effect tests are conducted to ensure the validity of volatility modeling. The empirical findings indicate that all return series exhibit non-normal distribution, strong volatility clustering, and significant ARCH effects. The estimation results show that both ARCH and GARCH parameters are statistically significant, with persistence levels close to unity across all markets, implying that volatility shocks tend to persist over a long period. These findings suggest that emerging stock markets in Asia are highly sensitive to external shocks and exhibit long-memory volatility behavior. The results provide important implications for investors and policymakers in designing effective risk management and market stabilization strategies.

This literature study aims to analyze the strategies of local cosmetic brands in providing product variants for different skin types, setting affordable prices for the teenage segment, and minimizing side effect risks to increase purchase intention among beginner users.
