Deret Fourier dan transformasi Fourier merupakan konsep penting dalam fisika dan komputasi yang sering kali sulit dipahami mahasiswa karena sifat matematisnya yang abstrak. Penelitian ini bertujuan mengembangkan simulasi dasar berbasis Microsoft Excel untuk memvisualisasikan kontribusi harmonik pada deret Fourier serta representasi frekuensi melalui Discrete Fourier Transform (DFT). Pada tahap awal, suatu fungsi periodik diselesaikan hingga diperoleh bentuk deret Fourier, kemudian setiap suku harmonik divisualisasikan dan ditampilkan superposisinya untuk menunjukkan pengaruh koefisien Fourier terhadap pembentukan gelombang kompleks menggunakan lembar kerja pertama pada Excel. Lembar kerja kedua menampilkan transformasi Fourier yang dilakukan secara manual menggunakan fungsi-fungsi dasar Excel sehingga menghasilkan spektrum frekuensi yang sesuai dengan karakteristik sinyal. Penelitian ini menunjukkan bahwa Excel dapat digunakan sebagai media pembelajaran untuk menjelaskan hubungan antara domain waktu dan domain frekuensi, sekaligus memperkenalkan konsep-konsep numerik seperti iterasi, aproksimasi, konvergensi, dan diskretisasi. Simulasi ini dapat dimanfaatkan dalam pembelajaran Fisika Matematika maupun Komputasi Dasar untuk membantu mahasiswa memperoleh pemahaman intuitif mengenai struktur frekuensi suatu sinyal.

This systematic review aims to synthesize and critically evaluate the application of ordinary differential equations (ODEs) in modeling and controlling autonomous vehicle dynamics from 2020 to 2025. Following the PRISMA framework, 36 peer-reviewed journal articles and conference proceedings were selected and analyzed to map model types, control strategies, and their practical trade-offs. The review identifies six primary ODE-based modeling approaches kinematic, dynamic, linear, nonlinear, single-track, and two-track each exhibiting distinct balances among accuracy, computational demand, and real-time feasibility. Integration with control methods such as PID, LQR, Model Predictive Control (MPC), and nonlinear techniques reveals context-dependent performance: while MPC and sliding mode control offer high accuracy and robustness, they impose significant computational burdens; in contrast, PID and LQR are lightweight but limited in nonlinear or high-disturbance scenarios. Critical gaps persist, including insufficient real-world validation, limited fusion of physics-based ODEs with data-driven learning, scarcity of open dynamic datasets, and unresolved real-time implementation challenges. The study concludes that model–control selection must be mission- and hardware-aware, and calls for stronger empirical validation, standardized benchmarks, and hybrid architectures combining ODE rigor with machine learning adaptability.

This study aimed to develop and validate a Project-Based Learning (PjBL)-based science module using water rocket experiments for the topics of motion, force, and pressure in junior high school. The study employed a Research and Development (R&D) approach using the 4D model, consisting of Define, Design, Develop, and Disseminate stages. The module was designed to support meaningful science learning by integrating project activities, inquiry-based student worksheets, and hands-on experimentation. Validation was conducted by three experts, including a science education expert, a science content expert, and an experienced science teacher. The validation focused on curriculum alignment, pedagogical appropriateness, content accuracy, worksheet quality, presentation, and assessment. The results showed that the developed module was categorized as very valid, with an average validation score of 89.8%. The highest score was obtained in presentation and language aspects (92%), while curriculum alignment and assessment each obtained 90%. The findings indicate that the module is feasible for use as a science teaching material in junior high school and is pedagogically promising for supporting active learning and scientific reasoning.

This study aimed to analyze the effectiveness of a Palembang ethnoscience-based physics module on student learning outcomes in potential and kinetic energy materials using a methodologically rigorous approach. Employing a quasi-experimental design with a one-group pretest-posttest pattern, the study involved 37 grade X students from SMAN 22 Palembang. Data were collected through learning achievement tests and analyzed using SPSS version 26, incorporating Shapiro-Wilk normality tests, Paired Sample T-Tests, Normalized Gain (N-Gain), Power Analysis, and outlier examinations. The results indicated mean pre-test scores of 61.22 (SD = 13.41) and post-test scores of 82.97 (SD = 9.96). The Paired Sample T-Test yielded a t-value of -11.217 with a significance of 0.000 (p < 0.05), indicating a significant difference and a strong association between module implementation and learning outcome improvements. The N-Gain value of 0.56 was categorized as medium, while the Effect Size (Cohen's d) of 1.84 demonstrated a very large impact, although this requires careful interpretation due to the within-subject design. Cohen's d<sub>z</sub>, calculated based on the standard deviation of difference scores, also produced a value of 1.84, confirming the consistency of the effect estimation. The study concludes that the Palembang ethnoscience-based physics module is positively associated with enhancing student learning outcomes. Integrating local wisdom bridges abstract concepts with students' real-life contexts, thereby rendering learning more meaningful.

Fluid dynamics and aerodynamic design of aircraft wings play a crucial role in improving flight efficiency, especially in the transonic regime. This research aims to analyze the application of partial differential equations (PDE) in aircraft design optimization and explore technical solutions to challenges that arise in Computational Fluid Dynamics (CFD). Our research method is Literature Review (SLR) using systematic steps such as database search, screening and thematic analysis based on references from recent scientific journals from 2020 to present (2025) through ScienceDirect, Google Scholar, arXiv,MDPI, DOAJ dan Academia . An initial search yielded 234,939 journals on PDEs, but after selection, 36 journals met the inclusion criteria and were thematically analyzed. The main findings show that the Navier-Stokes, Continuity, and Bernouli Equations are the cornerstones in understanding the fluid flow behavior around an Aircraft wing. Advances in CFD technology have led to innovations, such as the application of morphing wings and winglets, which can improve aerodynamic efficiency and reduce fuel consumption. However, challenges such as CFD solver robustness, design complexity with many variables, and geometry constraints are still an obstacle in aerodynamic optimization. It can be concluded that utilizing PDE in CFD contributes significantly to the development of higher efficiency aircraft and supports design innovations that are more adaptive to modern aerodynamic demands, especially in the transonic regime.
