This study aims to improve students' physics learning outcomes by applying differentiation learning to vibration and wave material. The population in this study were class VIII students of MTs Al-Washliyah Gedung Johor, Medan, for the 2022/2023 academic year. The sample in this study was class VIII-A as the control class totaling 40 students who were given conventional learning, and class VIII-B as the experimental class totaling 39 students who were given differentiated learning. The sampling method used was quasi-experimental and used a pretest-posttest control group design. Data on physics learning outcomes were collected using observation instruments and knowledge tests in the form of 10 essay questions. The increase in students' physics learning outcomes was seen by comparing the average hypothesis test scores customarily distributed and homogeneous in both classes. Based on the outcomes, the conclusion stated that the application of differentiated learning on vibration and wave material could significantly improve student learning outcomes.

This research aims to determine the level of students' problem solving abilities and to determine the difficulties experienced by students in solving problems based on problem solving abilities in dynamic fluid material. This type of research is qualitative research. The data sampling technique in this research uses a purposive sampling technique. The subjects in this research were class The results obtained show that SMA Negeri 8 Medan, MAN 1 Medan, SMA Private Dwiwarna, and Private SMA Islam Azizi have a good level of problem solving ability according to Heller at the problem focusing stage. the stage of describing the problem was categorized as sufficient, the stage of preparing a plan was categorized as sufficient, the stage of implementing the plan was categorized as inadequate, and the evaluating stage was categorized as insufficient. As for the difficulties experienced by students in solving problems based on problem-solving abilities in dynamic fluid material, namely Public High School 8 got 47.9%, MAN 1 Medan school got 45.9%, Dwiwarna Private High School got 42.0%, and Azizi Islamic Private High School got 37.8%.

This study aims to analyze the comparison of kinetic energy generated by five planets in the solar system and to visually simulate the supernova explosion process as a part of exploring cosmic energy dynamics. A quantitative computational method was employed using Python programming within the Visual Studio Code environment to calculate the kinetic energy of each planet based on its mass and orbital velocity. The data were presented on a logarithmic scale graph to clearly illustrate the wide range of energy magnitudes. The simulation results show that Jupiter generates the highest energy, approximately 3,39 × 1038 Joules, while Mercury yields the lowest, around 6,83× 1030 Joules. In addition to numerical analysis, this research includes a visual simulation of a supernova explosion to depict the dramatic transition of a massive star collapsing and releasing a tremendous amount of energy. The video illustrates the sequential phases of the explosion, including core collapse, shock wave formation, and the outward dispersal of stellar material represented by intense light bursts and dynamic color shifts. This visualization reinforces the understanding of the extreme energy scales involved in supernova events and their impact on the surrounding cosmic environment, including the possible formation of neutron stars or black holes. This study demonstrates how computational modeling and visual simulations can complement each other in explaining complex astrophysical phenomena and serve as an educational tool to enhance understanding of cosmic energy and stellar evolution.
