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.

Urolithiasis is stone-like material that settles in the urinary tract. The materials that make up urinary stones are calcium oxalate, uric acid, cystine and stuvite. Several medical procedures are often applied to cure this disease. However, many patients choose traditional treatment by consuming herbal medicine. The aim of this research is to show the structure and morphology of uric acid with Orthosiphon Aristatus. This is very important to study as a basis for producing herbal medicines in nanometer sizes. Samples were prepared before characterization. Urid Acid and Orthosiphon aristatus samples were weighed at a ratio of 0.1: 0.5 milligrams and dissolved in 100 milliliters of Aquabides. The samples were then characterized using XRD and SEM-EDX uric acid crystals mixed with Orthosiphon aristatus undergo progressive dissolution, characterized by an increasingly smooth surface and smaller particle size over time. The particle diameter of each sample changed from 37.64 to 32.83. This research will contribute to urinary stone sufferers choosing appropriate traditional medicine for the type of urinary stone they have

This study aims to model the pursuit motion between guided missiles and a circularly moving aircraft using Python-based numerical simulation. The target moves along a circular path with a constant angular speed, while the missile follows a pure pursuit strategy, continuously adjusting its path toward the target's current position. Two scenarios are simulated: single pursuer and multi-agent pursuers. In the single-missile scenario, the missile forms a spiral trajectory and intercepts the target in approximately 4.9 seconds. In the multi-agent configuration, five missiles launched from different vertical positions successfully destroy the target within 8.3 seconds, with the first interception occurring at 6.7 seconds. The model is based on numerical solutions of differential equations governing relative motion dynamics. The results demonstrate that increasing the number of pursuers enhances interception speed and system effectiveness. The study is supported by animations, distance-time graphs, and damage analysis.

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.
