Abstract

Double pendulum is a mechanical system that exhibits complex dynamic behavior, often used to study nonlinear dynamics and chaos. Along with the development of research, this system has been extended with the addition of several new constraints. This research aims to conduct a Systematic Literature Review (SLR) related to the extension of the double pendulum system and the formulation of the relevant equations of motion. The article search was conducted systematically, resulting in 27 documents that met the inclusion criteria. The results of the analysis show that the extension of the gantry pendulum crane system with a payload is the main focus in this study. In addition, the most frequently used decomposition model is a mathematical model with a Lagrangian approach. These findings provide deep insights for further development of mathematical models as well as their applications in the fields of robotics, system control, and dynamic structural analysis.

Abstract

This study aims to explore ethnophysical concepts embedded in Borobudur Temple and to develop a contextual physics enrichment book for senior high school students. Indonesia possesses a rich cultural heritage with strong potential for contextualized science education, and Borobudur Temple—an architectural masterpiece that embodies various physics principles—offers a unique opportunity to design culturally relevant learning resources. The research employed a Research and Development (R&D) approach using the AM3PU3 model and a one-group pretest–posttest design involving 74 students from SMA Negeri 1 Tengaran. Data were collected through expert validation, student questionnaires, and pretest–posttest scores, and analyzed using the N-Gain test. The findings indicate that mechanical concepts grounded in ethnophysics are present in the temple’s structure and can support culturally based physics instruction. The developed book received expert validation scores of 3.40 for content, 3.83 for language, and 3.63 for presentation (on a 1–4 scale). Student responses were also high, with scores of 4.00 for readability, 3.98 for effectiveness, and 3.90 for design (on a 1–5 Likert scale). The N-Gain result of 0.30 indicated a moderate improvement. These findings suggest that integrating ethnophysics may serve as a culturally responsive strategy to enhance students’ conceptual understanding and engagement in science education.

Abstract

We present a comprehensive quantum algorithm for computing Khovanov cohomology, a categorification of the Jones polynomial, together with a clear narrative that connects its motivation, construction, and implementation. By simulating Laplacian operators derived from the Khovanov cochain complex, we estimate cohomological dimensions using quantum phase estimation, thermal sampling, and Quantum Singular Value Transformation (QSVT). The framework explicitly exploits the Frobenius algebra structure and cobordism maps, showing how these topological tools translate naturally into unitary quantum operations. Worked examples for the trefoil knot and Hopf link illustrate each step, from encoding the cube of resolutions to constructing differentials and Laplacians. This narrative approach not only refines and operationalizes the Laplacian method introduced by previous works but also provides a practical roadmap for extending categorified invariants into the realm of quantum algorithms suitable for near-term devices.

Abstract

Technological developments are driving the transformation of science learning, including physics, from conventional to digital-based approaches. This study examines the use of a digital protractor in PhET simulations to verify Snell's Law (the law of reflection, θ₁ = θ₂) in geometric optics involving mirrors (plane, concave, and convex). This study aims to explore the innovation of digital protractor integration as a tool in PhET simulations on geometric optics, while also examining its implications as a learning aid for prospective physics teachers. This study is motivated by the challenges of abstracting optics material and the demands of STEM implementation in the Merdeka Curriculum. Employing a descriptive qualitative method with 15 physics students, the research found that this integration improves conceptual understanding despite technical issues such as inaccurate protractor placement and normal line errors. Data analysis confirmed Snell’s Law compliance, though success rates varied with procedural complexity. Students praised the dynamic visualization and efficiency but noted limitations, such as over-idealization. The results advocate for a blended learning approach, combining digital tools with traditional lab work to optimize optics education.

Abstract

The development of critical thinking skills is a curriculum mandate in Indonesia to prepare students for global challenges, yet existing assessments often fail to effectively measure these higher-order competencies. This study aims to analyze the developmental needs, characteristics, feasibility of an assessment instrument, and the effectiveness of its use in evaluating the critical thinking skills (CTS) of high school students on the topic of dynamic electricity. This is a research and development (R&D) study that employs the Four-D Model (define, design, develop, disseminate), as developed by Thiagarajan. The sample consisted of 30 students for a small-scale trial and 150 students for a large-scale trial. Data were collected through interviews, tests, questionnaires, and documentation. The data obtained from these methods were then analyzed using the Rasch Model to evaluate the psychometric properties of the instrument. The instrument was characterized by high-cognitive-level multiple-choice questions administered via the Google Forms platform integrated with AutoProctor. The research findings revealed the need to develop a critical thinking skills assessment instrument that meets the requirements of teachers, students, and conceptual frameworks.  The instrument's validity was established through two methods. First, an expert validation process yielded an average Aiken's V coefficient of 0.93. Second, data from empirical trials analyzed with the Rasch Model showed that all items met the ZSTD fit criteria for validity (-2.0 < ZSTD < +2.0). Item reliability was 0.74 and 0.92, with Cronbach's Alpha values of 0.84 and 0.87 (reliable). The item difficulty level was evenly distributed, the item discrimination index was 3.44 (good), and the instrument was free from bias. The average score across the 6 CTS indicators was 79.82, indicating that the assessment instrument for critical thinking skills on dynamic electricity is both feasible and effective for use.

Abstract

MA NU Banat Kudus has two educational programs: boarding and regular classes. These two programs differ, particularly in terms of independence; boarding school students live in school dormitories, which require them to be independent in many aspects of daily life. In addition, education in boarding schools is divided into two types, namely diniyah learning and regular learning, while regular students only have regular learning. Critical thinking is also an important aspect that must be considered. This study aims to analyze the differences in critical thinking skills and learning independence attitudes between boarding school and regular class students in physics learning at MA NU Banat Kudus. The method used in this study is a mixed methods with a triangulation design, combining a quantitative approach through tests and a qualitative approach through interviews. The study population consisted of grade XI students, divided into two groups: boarding and regular. Quantitative data analysis was carried out using the T test, while qualitative data were analyzed thematically. The results of the study showed that there was no significant difference in critical thinking between boarding school and regular students. Based on the t-test, a significant value of 0.67 was obtained, and the average results per aspect also showed no difference between boarding school and regular students. Meanwhile, the findings on student independence showed that boarding school students demonstrated better learning independence than regular students. This study recommends that schools develop more strategic planning for boarding programs to improve overall quality and implement active learning approaches, such as Problem-Based Learning, to enhance both critical thinking skills and learning independence among students in all types of schools.
