Abstract

This study aims to analyze the improvement of concept mastery of grade XI students about forces on objects in static fluid after being given interactive demonstration learning. The research method used is mixed method-embedded experimental design with one-group pretest-posttest design. The research subjects were students of class 4KJ SMK Universiti Malaysia and class H3 SMA Negeri 5 Malang. The instruments used were concept mastery test items regarding forces on objects in static fluid in the form of reasoned multiple choice questions, observation sheets, and interview guidelines. The results showed that the calculation of the d-effect size value of the learning applied to students of SMK Taman Universiti and SMAN 5 Malang was 4.50 and 4.28. The value of increasing student learning outcomes through the calculation of the average normalized gain is 0.88 and 0.83. The results also show that students can integrate Newton's laws in analyzing the problems of Archimedes' law after the learning is applied. For future research, similar learning can be applied to improve students concept mastery on other physics materials.

Abstract

This study aims to determine vehicle power in submarine vehicle design using regression analysis and enhance Students understanding of the simple pendulum concept. In this experiment, tests were conducted to analyze the relationship between various variables such as speed, force, and vehicle mass in relation to the power generated. The regression analysis results revealed a significant correlation between the applied force on the vehicle and the speed achieved, which was then used to calculate the required power for submarine vehicle design. Additionally, the study seeks to provide students with a deeper understanding of fundamental physics concepts, particularly the simple pendulum, by applying these concepts in the context of submarine vehicles. This research is expected to contribute to physics education and practical applications in vehicle design through regression-based analysis.
