From Bystander to Defender: Developing and Validating a Scale for Measuring Defending Behaviors Among Indonesian Adolescents in Bullying Contexts
Abstract: Defending behaviors play a crucial role in mitigating the negative effects of bullying on victims. However, many prevention and intervention programs promote peer defending without a clear understanding of the specific behaviors adolescent’s exhibit. To address this gap, a scale on defending behavior in bullying contexts among Indonesian adolescents was developed and validated using the Rasch Model. Rasch analysis, conducted with Winsteps software version 3.73, examined key psychometric properties, including discrimination index, including discrimination index, item difficulty, item-person fit, scale reliability, response category effectiveness, item bias, and respondent classification profiling. Data were collected from 142 junior high school students in Grades 7-9. The final version of the scale comprises 28 items distributed across four dimensions: solution focused defending, aggressive defending, comforting, and reporting to authority with 5 response options. The overall person-item interaction yielded a Cronbach’s alpha of 0.88, indicating excellent internal consistency. Additionally, the person reliability index was 0.86, reflecting high response consistency among participants. These findings confirm that the scale meets psychometric requirements and is a valid and reliable tool for assessing defending behavior in adolescent bullying contexts.

Modeling Infant Mortality Rate In North Sumatra Using Robust Regression With Generalized Scale (GS) Estimations
Infant Mortality Rate (IMR) is a key indicator in assessing the success of national health development programs. In recent decades, Indonesia’s IMR has declined, but consistent efforts are still needed, especially in provinces with high contributions. In 2023, North Sumatra ranked 3rd among provinces with the highest IMR. Therefore, an analysis is needed to identify factors that may contribute to infant mortality in this region. This study uses several variables, including the number of health centers, the percentage of births in health facilities, the number of low-birth-weight babies, and the number of pregnant women detected as HBsAg reactive. The aim is to develop an IMR model in North Sumatra that can serve as an evaluation reference. Regression analysis is a suitable method to understand the influence of these variables on IMR. However, unmet normality assumptions in classical regression may lead to inaccurate estimates. To address this, robust regression can be applied to obtain models that are more resistant to outliers. This study uses the Generalized Scale (GS) estimation method in robust regression. The resulting GS model produces an adjusted R² value of 86.76% and an AIC value of 108.2717.

Experimental and Numerical Study of Non-Pneumatic Tires with Honeycomb Structure on Varying Road Inclination Angles
Abstract: The increasing demand for vehicle mobility necessitates advancements in tire technology, with non-pneumatic tires (NPT) emerging as a promising alternative. NPTs address key limitations of conventional pneumatic tires, such as puncture risks and air pressure dependency. The honeycomb structure in NPTs is engineered to enhance load-bearing capacity and shock absorption, yet its performance under varying road inclination angles remains underexplored. This study integrates both experimental and numerical methodologies using the Finite Element Method (FEM). Three distinct NPT models with varying honeycomb cell angles were tested on inclined road surfaces (0°, 10°, and 20°). Experimental trials were conducted with a Universal Tensile Machine (UTM) to evaluate vertical reaction forces, while numerical simulations in ANSYS validated experimental outcomes under dynamic conditions. Key parameters such as von Mises stress distribution and stiffness were analyzed. Findings indicate that NPT models with smaller honeycomb cell angles exhibit higher vertical reaction forces, suggesting superior load-bearing capabilities on inclined surfaces. This research provides critical insights for optimizing NPT designs, particularly in applications where stability and durability are essential.

Abstract: This study aims to analyze the comparison of Euler method and FixedPoint method in solving the roots of non-linear equations numerically. The assessment criteria to be used include convergence, stability, and computational speed of each method. The equations used include trigonometric, pilinomial, exponential and logarithmic. Experiments were conducted 8 times with an error of 0.001 and using a maximum of 100 iterations. From the four cases of solving the tested equations, the results show that the FixedPoint method is more accurate in calculating the solution of non-linear equations compared to the Euler method, with 1 iteration on trigonometric equations. on polynomial equations the Euler method is faster than the Fixed point with 1 iteration. on exponential equations the Euler method is faster than the Fixed point with 1 iteration. In the second logarithmic equation Euler method is faster than Fixed point with 1 iteration. Therefore it can be said that the Euler method has a faster convergence rate and higher accuracy than the Fixed point method in all cases. So it can be said that Euler is the best method in solving the roots of non-linear equations. These findings provide new insights in choosing the right method for numerical applications in solving the roots of non-linear equations, as well as contributing to the development of more efficient numerical algorithms.

The Effect of Liquid Superficial Velocity on Two-Phase Air-Water Slug Flow in a Horizontal Pipe Using High-Speed Camera
Abstract: This study examines the impact of liquid superficial velocity (JL) on liquid slug length in two-phase air-water flow within a horizontal pipe. Experiments utilizing high-speed imaging were conducted to analyze slug length at different JL values while maintaining a constant gas superficial velocity (JG). Results show that increasing JL reduces slug length due to enhanced shear forces and turbulent interactions between the gas and liquid phases. At low JL, slugs are longer and exhibit high inter-slug variation, whereas at high JL, slugs become shorter and more uniform. Analysis of the slug length distribution reveals that the log-normal probability density function (PDF) effectively represents the trend, particularly at high JL, where slug fragmentation is more pronounced. The empirical model developed accurately predicts slug length, with most data falling within a ±25% error margin. Additionally, the average liquid slug length is 60% smaller than the maximum length and will never exceed this value, while the minimum slug length can decrease up to 630% of the average. These findings provide new insights into slug flow dynamics and offer valuable reference points for future studies on two-phase gas-liquid flow.

Development of an Interactive Adventure Game for Enhancing Mathematical Learning in Second Grade Students
Abstract: Mathematics is a fundamental subject taught across all educational levels, particularly in primary schools, where it serves as a foundation for understanding technology and science. However, second-grade students often struggle with mathematics due to a lack of motivation, primarily caused by conventional teaching methods that fail to engage them effectively. According to educators, students prefer learning through real-life examples that help them better understand the material and information presented. To address these challenges, an educational game was developed to support second-grade mathematics in primary schools, aligning with Indonesia's latest curriculum, Merdeka Curriculum. The game covers key mathematical topics, including numbers recognition, comparisons, addition, subtraction, geometric shapes, spatial figures, and patterns. To increase student engagement and sustain their interest, the game incorporates an adventure genre where students complete mini-games as part of various missions throughout the gameplay. Testing was conducted by comparing the pre-test and post-test scores of second-grade students after playing the adventure game. Students took a pre-test before playing the game and a post-test afterwards. The test results demonstrated a significant improvement in understanding, with average scores increasing from 8.21 to 9.07, and the score range shifting from 5-10 to 7-10. This confirms that the use of the game is effective in enhancing students' comprehension of mathematics.

Comparative Analysis of Halley and Hybrid Methods for Numerically Solving the Roots of Non-Linear Equations
Abstract: Finding the roots of nonlinear equations is a fundamental problem in numerical analysis with wide applications in engineering, science, and applied mathematics. The purpose of this study is to conduct a comparative analysis between Halley's method and a selected hybrid method for numerically solving the roots of nonlinear equations. Halley's method is a third-order iterative technique known for its fast convergence when provided with a good initial guess. On the other hand, hybrid methods are designed to combine the strengths of multiple numerical algorithms to enhance accuracy, stability, and robustness against different function characteristics. This study employs four test functions—polynomial, trigonometric, exponential, and logarithmic—to evaluate the performance of both methods in terms of convergence speed, computational efficiency, and sensitivity to initial guesses. The results indicate that Halley's method performs better in terms of speed under ideal conditions, while the hybrid method is more reliable in handling diverse nonlinear behaviors. Therefore, the appropriate method selection should consider both the nature of the function and the need for speed or stability in the computation.

Comparative Analysis of the Regula Falsi and Secant Methods for Numerically Solving the Roots of Nonlinear Equations
Abstract: This study aims to analyze and compare the effectiveness of two numerical methods, namely Regula Falsi method and Secant method, in solving the roots of non-linear equations. The non-linear equations used in this study include various types of functions, such as polynomial, trigonometric, exponential, and logarithmic functions. Both methods were tested through numerical simulations using MATLAB software to measure performance based on convergence speed, accuracy of results, and stability of the iteration process. The Regula Falsi method works based on linear interpolation between two points that have different function signs, while the Secant method uses two initial guesses without different sign requirements. The analysis shows that the Regula Falsi method is more stable but has slower convergence, while the Secant method converges faster but is less stable under certain conditions. By considering the advantages and disadvantages of each method, the selection of the optimal method is highly dependent on the characteristics of the function and the given initial conditions. This research contributes to understanding the fundamental differences between the two methods and provides practical guidance for researchers, academics, and practitioners in choosing the right numerical approach to solve various mathematical problems involving non-linear equations.

Application of New Literacy and Newton Rapshon Methods in Numerical Solving of Roots of Nonlinear Equations
Abstract: Solving non-linear equations is crucial in various scientific and engineering fields, especially when analytical solutions are difficult or impossible to obtain. This research compares the Newton-Raphson Method with the New Iterative Method for solving non-linear equations through numerical simulations using MATLAB. The objective is to evaluate both methods based on solution accuracy, convergence speed, and computational efficiency. The study examines four types of non-linear equations: trigonometric, polynomial, exponential, and logarithmic. Both methods are implemented in MATLAB and assessed based on the number of iterations, error values, and the accuracy of the obtained roots. The results indicate that the New Iterative Method is more efficient for solving trigonometric equations, requiring fewer iterations while maintaining comparable accuracy. In contrast, the Newton-Raphson Method performs better on polynomial equations, yielding more accurate results. For exponential and logarithmic equations, neither method proves optimal, with unrealistic or divergent root results and high error values. This highlights that the effectiveness of each method strongly depends on the type of function and the initial guess used.

Study of Heat Transfer and Bubble Dynamics in Pool Boiling with Orientation Angle Variations Using Dielectric Fluids on Porous Metal Foams
Abstract: The advancement of technology in various fields has increased the demand for efficient thermal management systems, one of which is two-phase cooling through pool boiling. This study investigates the effect of heater orientation angle variation on the heat transfer coefficient (HTC) and bubble dynamics using the dielectric working fluid HFE-7100 and metal foam as the test material. Experiments were conducted at orientation angles of 0°, 15°, and 30° using image processing techniques and measurement instruments such as thermocouples, pressure transducers, and a data acquisition system. The measurement data results show that as the orientation angle (θ) of the heater and test material increases, the HTC value decreases. The orientation angle (θ) = 0° has the highest ℎ value of 4.019 kW/m²K, while the orientation angle (θ) = 30° has the lowest ℎ̅ value of 1.042 kW/m²K. Image processing data show that as the orientation angle (θ) increases, the bubble distribution and growth area on the metal foam decrease. This reduction in bubble distribution and growth affects surface temperature and heat flux, which increase, but the overall heat transfer performance declines.

Semiotic Analysis of Social Media Advertisement in The Competitive Landscape of Early Childhood Education
Abstract: This study examines the use of semiotic elements in social media advertisements for early childhood education institutions using Charles Sanders Peirce’s triadic model of signs. In the increasingly competitive landscape of early childhood education, institutions utilize various marketing strategies to attract parents. However, the effectiveness of these advertisements depends on how icons, indexes, and symbols construct meaning and influence parental decision-making. This research employs a descriptive qualitative method, analyzing selected advertisements from various preschool institutions on social media. The data is examined using Peirce’s semiotic framework, identifying the role of visual and textual signs in shaping parental perceptions. The findings reveal that icons, such as images of joyful children and interactive learning environments, create an impression of a nurturing and stimulating school setting. Indexes, including bright colors, playful fonts, and engaging visuals, evoke feelings of warmth, fun, and child-friendliness. Symbols, such as accreditation badges, exclusive program labels, and statistical claims, reinforce credibility and the institution’s competitive advantage. While these strategies effectively attract prospective students, they may also contribute to unrealistic parental expectations shaped by idealized marketing narratives. This study highlights the need for a critical understanding of how semiotic elements influence consumer perception in the competitive early childhood education sector.

Numerical Simulation to Find Root Solution of Nonlinear Equation with Hybrid and Laguerre Method
Abstract: Non-linear equations are a form of mathematical problem that is often found in various fields of science, such as engineering, physics, and computers. The solution cannot always be done analytically, so the numerical approach becomes a commonly used solution. This research discusses and compares two numerical methods, namely the Hybrid method and the Laguerre method, in numerically finding the roots of non-linear equations using Matlab software. The Hybrid method combines the advantages of two methods, such as Newton-Raphson and bisection, to improve convergence speed and stability. Meanwhile, the Laguerre method is known to be efficient in solving high degree polynomial equations. The assessment is based on three main aspects: convergence speed, stability, and computational efficiency. Simulation results on various types of functions - polynomial, exponential, trigonometric, and logarithmic-show that the Hybrid method tends to have shorter computation time in some cases, while the Laguerre method shows stable performance in most trials. This study concludes that both methods have their own advantages depending on the characteristics of the function being solved. Therefore, the results of this study can be an important reference for the selection of appropriate numerical methods in the application of solving non-linear equations effectively and accurately.

A Scenario-Based Stochastic Optimization Model for Consolidated Product Shipment under Supply Uncertainty
Abstract: Efficient logistics system planning is key to facing increasingly tight business competition. The problem of product distribution from multi-suppliers to ports is often faced with supply uncertainty and limited transportation and storage capacity, thus requiring an adaptive and optimal decision-making approach in responding to supply dynamics. This study proposes a scenario-based stochastic mixed-integer linear programming (SMILP) model to support decision-making in a multi-supplier distribution system to ports through a single hub under supply uncertainty. This model takes the case of a product delivery system with consolidation in the sago-starch supply chain, where shipping companies and suppliers are faced with supply fluctuations, limited warehouse capacity, and challenges in selecting the appropriate type of ship. This model considers supply uncertainty, limited warehouse capacity at suppliers, and the selection of large ship types as transportation modes. The optimization objective is to minimize the total logistics cost, which includes shipping, storage, and ship activation costs, while ensuring the fulfillment of minimum demand at the port each period. The implementation results show that this model is effective in adapting to supply variations, utilizing transportation and storage capacity efficiently, and consistently selecting a combination of shipping and inventory strategies that minimize costs in the face of uncertainty.

Comparison of the Accuracy of Solution of Nonlinear Equations by Chebyshev and Euler Methods through Numerical Simulation
Abstract: Non-linear equations have an important role in various fields of science such as physics, biology, and especially mathematics. The complexity of the mathematical form of non-linear equations often makes it difficult to solve analytically, so numerical approaches become a widely used alternative. Numerical methods offer approximate solutions to analytical solutions with certain errors, but are still reliable for various practical purposes. This study compares the accuracy of two numerical methods, namely the Chebyshev method and the Euler method, in solving non-linear equations through numerical simulations. The Chebyshev method is used to analyze the proportion of values within a certain standard deviation from the mean, while the Euler method is known as a simple one-step method with low accuracy, but faster computation process. Simulations were performed on four types of functions: trigonometric, exponential, logarithmic, and polynomial. The simulation results show that the Euler method gives a faster convergence rate than the Chebyshev method in all cases of the functions tested, so it is considered more accurate in solving the roots of non-linear equations in the context of this study. This finding is expected to be a reference in the selection of efficient and appropriate numerical methods in solving non-linear mathematical problems.

Abstract: This study aims to analyze the comparison of Fixetpoint and Halley methods in numerically solving the roots of non-linear equations. The assessment criteria to be used include convergence, stability, and computational speed of each method. The equations used include trigonometric, pilinomial, exponential and logarithmic. Experiments were conducted 8 times with an error of 0.001 and using a maximum of 100 iterations. Of the four cases of solving the tested equations, the fixetpoint method is faster than the halley method with 5 iterations on trigonometric equations. In polynomial equations the fixetpoint method is faster than newton rapshon with 100 iterations. in exponential equations the fixetpoint method is faster than hallley with 1 iteration. In the logarithmic equation the fixetpoint method is slower than the halley method with 14 iterations, therefore it can be said that the fixtpoint method has a faster convergence rate and higher accuracy than the Halley method in most cases. So it can be said that Fixetpoint is the best method in solving the roots of non-linear equations. These findings provide new insights in choosing the right method for numerical applications in solving the roots of non-linear equations, and contribute to the development of more efficient numerical algorithms.

Comparative Analysis of Newton Rapshon and Chebyshev Methods for Numerical Solving the Roots of Nonlinear Equations
Abstract: This study aims to analyze the comparison of Newton-Raphson and Chebyshev methods in numerically solving the roots of non-linear equations. The assessment criteria to be used include convergence, stability, and computational speed of each method. The equations used include trigonometric, pilinomial, exponential and logarithmic. Experiments were conducted 8 times with an error of 0.001 and using a maximum of 100 iterations. Of the four cases of solving the tested equations, the newton rapshon method is faster than the cchebyshev method with 2 iterations on trigonometric equations. on polynomial equations the chebyshev method is faster than newton rapshon with 3 iterations. on exponential equations the chebyshev method is faster than newton rapshon with 14 iterations. In the logarithmic equation both methods do not find results or errors, therefore it can be said that the chebyshev method has a faster convergence rate and higher accuracy than the Newton-Raphson method in most cases. So it can be said that Chebyshev is the best method in solving the roots of non- linear equations. These findings provide new insights in choosing the right method for numerical applications in solving the roots of non-linear equations, and contribute to the development of more efficient numerical algorithms.

Juggling in Between Work, Home, and University: Female Master Students’ Experience of Multi Roles Conflict
Abstract: Multi roles conflict (MRC) refers to tensions that are created due to incompatible multiple roles and responsibilities. Female master’s students face a heightened risk of experiencing MRC, as they must balance academic, professional, and family roles simultaneously. This paper reviews theoretical frameworks to analyse MRC experienced by female students in Indonesia context. Based on literature research, this paper explores the challenges to be faced, psychological impacts, and coping strategies related to MRC. The studies reviewed indicate that the challenges might be faced by female master’s students are role overload, time-based conflict, strain-based conflict, behavior-based conflict, and role ambiguity. The psychological consequences of MRC entail stress, anxiety, depression, irritability, lowered self-esteem and social withdrawal. Meanwhile the coping strategies involve structural role redefinition (seeking support from family, supervisors and colleagues, timely communication, and job flexibility), personal role redefinition (cognitive reframing, setting clear expectation), and reactive role behaviour (time management and developing personal hobbies). Understanding the multiple role challenges faced by female master’s students may contribute to their institution, workplace, and organization for enhancing their well-being and promoting a more sustainable balance among academic, personal, and professional role.

Differential Pressure Fluctuations Analysis of Stratified to Annular Air-Water Transition Flow in Horizontal Pipe
Abstract: The transition of flow patterns from stratified to annular regimes in two-phase systems plays a critical role in determining flow stability, pressure drop, and the overall performance of pipeline operations. This study examined differential pressure fluctuations during the transition regime of air–water two-phase flow in a horizontal acrylic pipe with an internal diameter of 26 mm. Experiments were conducted at 12 flow conditions, with superficial gas velocities (JG) ranging from 8 to 14 m/s and liquid velocities (JL) from 0.08 to 0.2 m/s. Differential pressure data were collected in time series and analyzed using the Probability Density Function (PDF) and Power Spectral Density (PSD). The results indicated that increasing JG and JL enhanced interfacial interactions, promoted disturbance waves, and initiated entrainment, leading to the formation of annular flow. PDF analysis showed a shift from narrow peaks in stratified flow to wider, multi-modal distributions in the transition regime, signifying pressure instability. Correspondingly, PSD analysis revealed a rise in dominant frequency and spectral energy as the flow became more dynamic. These findings demonstrated that time series-based PDF and PSD analysis could effectively capture the evolving characteristics of flow regime transitions and serve as diagnostic tools for understanding two-phase flow behaviour.

Guru “Digugu Lan Ditiru”: A Psychological Review
Abstract: In Javanese society, a teacher is often regarded as “digugu lan ditiru”, meaning obeyed and emulated. This phrase reflects the teachers honorable position as a role model and guide for the community. This study aims to explore the meaning of “digugu lan ditiru” from a psychological perspective using a literature review method. The findings highlight the concept of Dasa Ma (10 M), which outlines essential behaviors for teachers: manemboh (faith and devotion), momong (guiding), momot (patience and resilience), momor (adaptability and openness to innovation), mursid (noble character and visionary thinking), murokapi (beneficial influence), mapam (strong mental and physical endurance), mituhu (loyalty), mitayani (reliability), and mumpuni (mastery of skills). These qualities help a teacher gain student’s trust and obedience. Through the process of modeling, as explained in Albert Bandura’s social learning theory, students see their teachers as role models, internalizing values and behaviors. Thus, being a teacher who is “digugu lan ditiru” is not only a social expectation but also a psychological process that infulences student development.

Project-Based Learning Approach to Improve Students' Mathematical Numeracy Literacy: a Systematic Literature Review
Abstract: The efficacy of project-based learning (PjBL) strategies in enhancing students' mathematical numeracy literacy is investigated in this comprehensive research review. Early development of quantitative numeracy skills is essential in this era of growing complexity. This study intends to determine the features, application, and effects of PjBL on the growth of students' mathematical numeracy literacy at different educational levels by a methodical review of recent literature. The review's findings show that, in comparison to more conventional teaching approaches, project-based learning greatly enhances students' problem-solving skills. Students who participated in STEM-focused project learning demonstrated gains in teamwork, critical thinking, and the capacity to relate mathematical ideas to practical issues. Mastery of ideas and numeracy abilities were favorably connected with PjBL's ability to boost students' motivation and involvement in the mathematics learning process. According to the research review, PjBL fosters four essential competencies: collaboration, representation, intra-mathematical connections, and the development of a positive identity toward mathematics. In the meantime, current PjBL implementations continue to underrepresent computational thinking abilities. The review also demonstrates that the quality of the learning design, teacher assistance, and implementation context all affect how well PjBL strengthens numeracy. Based on the results, this review comes to the conclusion that students' mathematical numeracy literacy can be greatly enhanced by using a project-based learning strategy. This method fosters higher-order thinking abilities and learning motivation in addition to improving mathematics technical proficiency. Teachers must continue their professional development in order for PjBL to be implemented successfully, with an emphasis on integrating pedagogy and technology. In light of the demands of children from diverse backgrounds, this study suggests that educators, researchers, and practitioners work together to create a particular PjBL framework for enhancing mathematical numeracy literacy. The usefulness of PjBL in blended learning and online learning environments, as well as the creation of reliable evaluation tools to gauge how effectively students' numeracy literacy is developing using the PjBL approach, require more research.

Strategic Planning: Developing an HR Strategic Plan in Islamic Education Institutions
Abstract: This study aims to analyze strategic planning in human resource management (HRM) in Islamic educational institutions through a Systematic Literature Review (SLR) approach. Literature sources were obtained from Scopus, DOAJ, and Google Scholar databases, with selection of articles published in the last 10 years. The results showed that HR strategic planning is a key factor in improving the effectiveness of Islamic education institutions. This approach includes the integration of Islamic values with modern management practices, transformational leadership, community-based strategies, as well as the use of planning tools such as balanced scorecards. However, there are still challenges in the implementation of HR strategic planning, such as limited understanding of Islamic-based HR management theories, lack of resources in policy implementation, and the gap between the sharia-based curriculum and the needs of the global job market. In addition, the lack of cooperation with Islamic financial institutions and limited digital-based training programs, creativity, and critical thinking are obstacles in facing the Society 5.0 era. Therefore, further research is needed on an adaptive and innovative HR strategic planning model to improve the competitiveness and sustainability of Islamic education institutions amid global dynamics.
