Abstract

The knowledge of the student about harmonic oscillators is quite limited. The purpose of this PPM is to 1) increase the knowledge of Bengkulu City 5 SMAN students about Quantum Harmonic Oscillators and their application in everyday life 2) improve the skills of Bengkulu City 5 High School students in calculating Quantum Harmonic Oscillators using the fast-forward method to accelerate quantum dynamics adiabatic. PPM was carried out at SMAN 5 Bengkulu City, especially in class 12 IPA 5 on October 24, 2022. The research method was carried out in three stages. The first stage is preparation. The second stage is the presentation of quantum harmonic oscillator material using research instruments in the form of power points, the third stage is research evaluation.

Abstract

Purpose of the study: The aim of this study is to develop and evaluate the effectiveness of a learning media called MITEDA (Mitigation of Earthquake Damage), which is based on the STEM approach and computational thinking, to support the teaching of wave physics. The study focuses on both the development process of the media and its impact on improving students’ computational thinking skills through contextual problem-solving using earthquake simulation and sensor-based data. Methodology: The research method used is Research and Development (R&D) with the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model. Tools used include Arduino Uno, SW-420 vibration sensor, LCD 16x2, and a buzzer. Software includes Arduino IDE and Proteus. Data collection used expert validation sheets, student questionnaires, observations, and computational thinking tests. Main Findings: The MITEDA learning media, comprising a digital seismograph kit and instructional module, was rated “highly feasible” by experts (Aiken’s V ≥ 0.80) and received positive student feedback for usability and engagement. Statistical analysis showed a significant improvement in computational thinking skills for the experimental group (N-Gain = 0.84) compared to the control group (N-Gain = 0.56), t(69) = 8.875, p < 0.001, d = 2.716, with the highest gains in abstraction and consistent high-level algorithmic performance. Novelty/Originality of this study: This study presents an innovative learning media, MITEDA, integrating STEM and computational thinking through earthquake simulation using Arduino-based sensors. It advances wave physics learning by providing real-time vibration data and contextual problem-solving, enhancing students’ analytical skills.

Abstract

This research is theoretical research with a literature study that examines methods to maintain characteristics of electrons when moving in a quantum system at the potential barrier. Attempts to maintain the characteristics of electrons in quantum systems are known as adiabatic. The method used in this research is the fast-forward method. This method was first introduced by Masuda and Nakamura in 2010. The fast-forward method is applied to barrier potential in case of electron energy larger and smaller than the potential barrier. This research focuses on preserving the characteristics of electrons by determining the regularization phase and additional potential of the quantum system at the barrier potential. The wave function solution of the system at the potential barrier is approximated by the Schrödinger equation into three regions for each case. The wave function of each region is regularized to be an adiabatic wave function and an additional term in the form of regularization phase (θ) is obtained. Given the regularized Hamiltonian, the additional potential (Ṽ) is obtained. The obtained regularization phase and additional potential ensure the quantum system at the potential barrier is in the same state from the initial state to the final state
