Curpose of the study: The purpose of the research that has been carried out is to analyze the effectiveness of cooperative problem solving learning with the science process skills approach in improving students' understanding of the subject of simple harmonic motion. Methodology: The method used is a quasi-experiment with a pretest-posttest control group design. The subject of the study was students of class X science from two high schools who were selected purposively. The data was analyzed with a Statistical Descriptive Test to describe the learning outcome data from two sample classes. Main Findings: The results of the analysis showed that the average posttest score of the experimental class was higher than that of the control class. The average score of the experimental class showed a high improvement category, while the control class only achieved a moderate category. CPS learning with the SPS approach has proven to be effective because it combines group cooperation and scientific exploration. Students can associate theory with practice, so that the understanding of concepts becomes more deep. Novelty/Originality of this study: This study introduces a novel integration of Cooperative Problem Solving (CPS) with Science Process Skills (SPS) in teaching Simple Harmonic Motion. Unlike traditional methods, this approach fosters both collaborative problem-solving and scientific thinking, enhancing students' conceptual understanding and practical application. It advances existing knowledge by demonstrating how CPS-SPS synergy can bridge theoretical physics and real-world problem-solving skills effectively.

The development of science and technology in the 21st century necessitates strong scientific literacy among students, yet Indonesian students' PISA scores in this area remain low. Conventional physics teaching materials often lack interactivity and fail to engage students actively, especially for abstract topics like momentum and impulse. This research addresses the gap by developing guided inquiry-based teaching materials assisted by virtual laboratories (V-Lab) for momentum and impulse, aiming to improve senior high school students' scientific literacy. The study employed a Research and Development (R&D) method focusing on the define, design, and develop stages. Module feasibility was assessed through validation by material and media experts using questionnaires (1-4 Likert scale), yielding quantitative scores and qualitative feedback. Initial field testing involved 32 10th-grade students and utilized readability questionnaires, learning interest questionnaires, and pre-post science literacy tests, analyzed descriptively. Results showed high feasibility: material expert validation at 91.6% (Very Good) and media expert validation at 84.0% (Very Good). Qualitative feedback affirmed the module's strengths and provided suggestions for refinement. Initial field testing indicated very good student readability (86.3%) and learning interest (82.0%). Science literacy improved from a pre-test average of 45.2% to a post-test average of 75.8%, with a Normalized Gain (N-Gain) of 0.56 (Medium effectiveness). The study concludes that the developed V-Lab assisted guided inquiry teaching materials are highly feasible and effective for enhancing students' science literacy. The module offers a valuable, interactive resource for physics education, with potential for wider application

Liquefied Petroleum Gas (LPG) leakage is one of the major causes of household fires. This study aims to design and develop an Internet of Things (IoT)-based LPG gas leakage detection system using an ESP32 microcontroller and an MQ-2 gas sensor. The system implements a dual-threshold rule method that classifies conditions into three categories: Safe (<100 PPM), Warning (100–299 PPM), and Danger (≥300 PPM), while controlling an LED, buzzer, and exhaust fan as early warning devices. The testing results show that the system is capable of detecting gas concentrations within a range of 2.0 PPM to 10000.0 PPM, activating warning devices according to the detected condition, and sending real-time notifications to the user's smartphone through the Telegram application. In addition, monitoring data, including date, time, PPM values, and system status, are automatically stored in Google Spreadsheet every 15 seconds. Based on the testing results, the developed system performs effectively as an LPG gas leakage detection and monitoring device for household applications.
