Objective: This study aims to develop and evaluate the effectiveness of G-Sites-based learning media to improve students' critical thinking skills, particularly in understanding the physics topic of the electrical obstacle series. With the growing need for engaging and flexible digital learning solutions, this research addresses how interactive web-based media can enhance learning outcomes in science education. Method: The research employed a 3D development model consisting of Define, Design, and Develop. Learning needs were identified through student surveys, and the media was designed using G-Sites, which incorporated features such as videos, quizzes, and interactive simulations. The developed media was validated by experts and tested on 59 high school students in a limited classroom trial at SMAN 1 Ngimbang. Data were analyzed quantitatively using validity scores and gain scores from pre-and post-tests. Results: The validation results showed that the learning media was highly valid in terms of design, content, interactivity, and technical aspects, with scores exceeding 90%. Student learning outcomes improved significantly, as shown by increased post-test scores. Feedback indicated that students found the media engaging, accessible, and preferable compared to conventional methods. Novelty: This study introduces the innovative use of Google Sites as a free, accessible, and flexible platform for developing interactive physics learning media. Unlike many commercial platforms, G-Sites allows educators to independently create customized, multimedia-rich content tailored to their students' needs, representing a practical and scalable solution for digital learning in resource-constrained environments.

Objective: Research to describe the improvement of students' critical thinking skills with the Smartphone-Simulation assisted inquiry learning model. Method: This research employed a quantitative descriptive approach, utilizing the data collected. Primary data were obtained from the results of skills tests, observations of learning implementation, and student responses. Furthermore, secondary data was obtained from a literature review to support the primary data. Results: The smartphone simulation media-assisted inquiry model has a positive effect on improving students' critical thinking skills, with an N-Gain score of 0.675. The inquiry learning model, combined with critical thinking, is closely related, focusing on high-level thinking processes that are systematic, reflective, and experience-based. Novelty: Dynamic visualization through the use of smartphone simulations greatly helps improve students' critical thinking skills, accelerating and strengthening the development of their critical thinking in real terms. This is achieved through information transfer and the construction of understanding through active and reflective thinking processes. It is hoped that this research can be one of the implementations of innovative learning planning assisted by digital media.

Objective: This study aims to describe the application of adiabatic coupler modification in efficient optical coupler engineering and to emphasize its contribution to the achievement of SDG 9 (Industry, Innovation, and Infrastructure). Method: The method used is a literature study through a review of relevant articles and Python software-based analysis to evaluate the impact of coupler modifications, as an effort to strengthen theoretical findings. Results: The results of this study show that the invariance principle-based reverse engineering approach is practical in designing directional couplers on waveguides. Combined with perturbation analysis of the coupled mode equations, this method produces directional couplers that are highly robust to parameter variations such as coupling coefficient and wavelength. However, changes in scale or resonance through Python integration do not significantly affect the apparent deviation of the coupler wave, so the efficiency of the coupler is mainly determined by the coupling coefficient and wavelength variations. Novelty: This study highlights the novelty of utilizing the invariance principle and resonance modification as an efficient and straightforward approach for adiabatic coupler optimization. Furthermore, the results demonstrate the significant contribution of adiabatic couplers to SDG 9 through their support for the development of sustainable optical communication infrastructure, increased energy efficiency, and innovation in next-generation optical technologies.
