Abstract

Abstract: At present students often have difficulty answering and solving questions, especially international standard questions in the form of PISA. The existence of a difficulty faced by students is a lack of interest in reading so that literacy in Indonesia is very low, especially on the results of the PISA test. The purpose of this study was to find out the difficulties experienced by students in answering PISA questions like the context of North Sumatra, the factors that influence difficulties in answering questions generally lie in the use of formulas, understanding or the ability to digest the language in the texts of PISA questions. This type of research is descriptive research that aims to identify and describe the difficulties experienced by students in answering PISA Like questions in the context of North Sumatra. The results of this study indicate that in answering PISA questions students experience difficulties in understanding the questions, changing and solving real problems in the form of science, namely physics, and interpreting physics solutions in real situations. The results show that difficulties in understanding questions and changing real problems into physics are more dominant than difficulties in PISA biology questions.    Keywords: student difficulties, pisa, pisa like the context of north sumatra

Abstract

In science learning there are many important concepts that must be understood. The solar system is a complex and abstract material because it cannot be seen directly by human senses resulting in students experiencing misconceptions.  Interactive learning media is needed to help students understand concepts. One of the learning media that can be applied is augmented reality based on dry lab simulation. This study aims to determine the effectiveness of using Dry Lab simulation to overcome misconceptions of earth and solar system material in junior high school. This research uses experimental research methods with Pre-experimental research models. The overall research results, the average effectiveness was 45.16%, which showed less effective results. Partially for the two sub-concepts of planets and solar and lunar eclipses, the average effectiveness is 65.5%, which shows that the dry lab simulation is effective in changing students' misconceptions

Abstract

This study aims to describe the enhancement of students' science communication skills through the application of guided inquiry learning models in laboratory activities. The method used to describe science communication skills is to use pre-experiment research. The samples used in this study were 60 physics education students in the odd semester 2023/2024 who took basic physics practicum courses. The implementation of the guided inquiry learning model in the four meetings. The results of improving science communication skills were based on three indicators that researchers have limited. The result analysis used non-test instruments like observation sheets. The sub-scientific communication skills are: 1) searching information, 2) scientific writing, and 3) representing information. Based on the observation results, it was found that the application of the guided inquiry learning model can train students' science communication skills in sub-skills of seeking information with a percentage increase of 74%, sub-skills of scientific writing with a rise of 67% and sub-skills of representing information at an increase in percentage of 76%. Each average score on the third and fourth meetings shows that science communication skills are in the very skilled category

Abstract

The rapid development of science and technology demands that students master essential 21st-century skills, particularly the 4Cs: critical thinking, creativity, collaboration, and communication. This study aims to map senior high school students’ mastery of 4C skills in Renewable Energy learning and to examine differences across the four components. A quantitative descriptive design was applied involving four schools selected through cluster sampling, with each school representing one 4C component. Research instruments consisted of validated and reliable tests and Likert-scale questionnaires. Data were analyzed using descriptive statistics to categorize skill levels and the Kolmogorov–Smirnov test to assess normality. As most data were not normally distributed, the Kruskal–Wallis test was employed to analyze differences among the skills. The results reveal significant variation in students’ 4C performance. Critical thinking and collaboration were categorized as high, while creativity and communication showed more diverse distributions. The Kruskal–Wallis test produced an Asymp. Sig value of < 0.05, indicating significant differences among the four skill domains. These findings suggest that 4C skill development is uneven and influenced by learning experiences and instructional strategies. Therefore, systematic mapping of 4C skills is crucial for curriculum improvement and the design of targeted instructional interventions.

Abstract

The Time-Independent Schrödinger Equation (TISE) plays a crucial role in quantum mechanics for obtaining the eigenenergies and wave functions of a system. This research numerically solves the TISE for the one-dimensional infinite potential well model by applying the Numerov method combined with the shooting technique. The Numerov method was chosen because it has an order of accuracy of O, making it effective for solving second-order differential equations with a very small truncation error. Numerov is used to solve the second order differential equation with a high degree of accuracy, while the shooting technique is applied to determine the eigenenergies that satisfy the physical boundary conditions of the system. Wave function normalization is performed using the Simpson integral so that the total probability is. Numerical validation is carried out by comparing the computed eigenenergies to the analytical solution  in dimensionless units for  up to . The results show that the numerical energies have a relatif error in the range of order  to , indicating that the Numerov method is capable of producing very accurate and consistent solutions. Based on these findings, the Numerov method can be used effectively in solving quantum mechanics problems that do not have analytical solutions.

Abstract

Interstellar exploration faces fundamental challenges due to the time dilation effects of Einstein's theory of relativity. This review presents a comprehensive analysis of the principle of time dilation, implications for interstellar missions, as well as cutting-edge technologies that utilize this principle. The Systematic Literature Review (SLR) method with PRISMA approach was applied, resulting in 42 relevant articles that met the inclusion criteria. The review results show that: (1) the effects of time dilation pose significant challenges in interstellar mission planning, particularly in the aspects of navigation, communication, and crew biology; (2) the development of cutting-edge technologies such as the Breakthrough Starshot relativistic vehicle, high-precision atomic clocks, and autonomous AI systems offer innovative solutions to overcome these challenges; (3) the integration of relativity understanding with these advanced technologies opens up new opportunities to realize interstellar exploration in the coming decades. These findings confirm that although time dilation is a major obstacle, the development of revolutionary technologies can turn it into a supporting factor in the realization of interstellar missions.

Abstract

This study presents a computational visualization of the stationary states of a particle confined in a one-dimensional infinite potential well, formulated entirely from analytical solutions and implemented in a cloud-based Python environment. Using Google Colab, wave functions, probability densities, and nodal structures were generated for several quantum numbers to illustrate fundamental quantum-mechanical characteristics, including energy quantization, spatial oscillatory behavior, and the emergence of classical correspondence at higher energy levels. The resulting visualizations offer a clear representation of the spatial distribution of quantum states, thereby supporting a conceptual understanding of the underlying analytical model. As a novelty, this study introduces a Colab-based analytical–numerical combination as a visualization medium, a format rarely explored in depth in quantum-well learning contexts. Beyond instructional applications, the modeled system accurately reflects the essential physical behavior of electrons in semiconductor quantum wells, where quantized subband energies and wave-function profiles significantly influence optical and electronic transitions.  These findings demonstrate that analytically derived quantum models, when integrated with computational visualization, can effectively enhance conceptual comprehension while offering insight into the fundamental principles governing modern optoelectronic structures.

Abstract

Critical thinking is an essential competency in 21st-century science learning that supports students in analyzing information, solving problems, and making evidence-based decisions. However, the profile of junior high school students' critical thinking skills on the topic of temperature and heat has not been comprehensively mapped using indicator-level diagnostic data. This study aims to describe the critical thinking profile of seventh-grade students at SMPN 4 Mesuji Makmur on the topic of temperature and heat, based on Ennis's (2011) five critical thinking aspects and 12 indicators, using a descriptive instrument supported by qualitative interview data. A quantitative descriptive approach supported by qualitative interview data was employed. Subjects comprised 94 seventh-grade students selected through total sampling. The instrument was a 25-item multiple-choice critical thinking test based on 12 Ennis (2011) indicators (2–3 items per indicator), validated by two expert lecturers through Content Validity Ratio (CVR ≥ 0.42), Product Moment correlation (r > 0.361), and Cronbach's Alpha reliability (α = 0.78). Data were analyzed using descriptive statistics and the interactive model of Miles, Huberman, & Saldaña (2014). Results showed that the average critical thinking achievement was only 46.77% (SD = 8.43), in the low category (Arikunto, 2013), with 71 students (75.5%) in the low category, 18 students (19.1%) in the medium category, and 5 students (5.3%) in the high category. All five aspects were low: providing simple explanation (47.47%), building basic skills (43.94%), inferring (45.45%), providing advanced explanation (43.94%), and managing strategies and tactics (53.03%). Building basic skills and providing advanced explanation were the weakest aspects. These findings suggest the need for inquiry-based and practicum-oriented instruction specifically targeting observational reasoning and conceptual definition skills in temperature and heat learning.

Abstract

Indonesia's coastal regions face significant threats from climate change, including rainfall uncertainty, rising temperatures, and sea level rise. This study aims to explore the potential of machine learning algorithms in predicting climate parameter changes in the coastal areas of Minangkabau, Pesawaran, and Maritim Panjang. Daily climatological data obtained from the Meteorology, Climatology, and Geophysics Agency (BMKG) were used as the basis for model training. Three primary algorithms were tested Random Forest, XGBoost, and Long Short-Term Memory (LSTM) selected for their capability to handle complex and temporal data. The research methodology included data preprocessing, model training, cross-validation, and predictive performance evaluation using metrics such as Root Mean Square Error (RMSE), Mean Absolute Error (MAE), and the coefficient of determination (R²). Preliminary results show that LSTM excels in time series prediction, while XGBoost offers a good balance between speed and accuracy. These findings indicate that machine learning-based approaches have strong potential as decision-support tools for climate change mitigation and adaptation planning in Indonesia’s coastal regions.
