Abstract

Model Landau Zener atau yang biasanya disebut LZ adalah model dengan  dua keadaan yang paling banyak digunakan dalam meningkatkan dinamika sistem spin  kuantum. Pada Penelitian ini menggunakan metode studi literatur dan kuantitatif dimana metode studi literatur ini mengumpulkan data dari sumber penelitian sebelumnya maupun buku yang berkaitan,dan menggunakan metode kuantitatif menggunakan persamaan untuk mencari metode tersebut dan untuk mendapatkan grafik. Tujuan dari penelitian ini adalah mengetahui bagaimana  mempercepat sistem Landau Zener dalam mempercepat  dinamika kuantum adiabatik dengan mendapatkan Hamiltonian tambahan menggunakan metode shortcut to adiabaticity  untuk  mempercepat dinamika kuantum adiabatik. Untuk  mempercepat proses dinamika kuantum dalam waktu yang singkat terdapat dua cara yaitu metode shortcut to adiabaticity dan fast forward.. Metode fast forward dapat dipergunakan untuk memindahkan elektron tanpa mengganti sifat asli dari elektron tersebut. Metode ini pertama kali diperkenalkan oleh Masuda dan Nakamura pada tahun 2010. Hasil yang di dapatkan dari penelitian ini yaitu untuk mencari nilai   (Hamiltonian) tambahan pada metode fast forward dibutuhkan hanya satu vector eigen sedangkan pada metode STA lebih kompleks dengan menjumlahkan nilai  dari semua nilai eigen untuk mendapatkan nilai Hamiltonian tambahan.Dari hasil penelitian dapat disimpulkan bahwa metode fast forward lebih sederhana yang hanya menggunakan 1 nilai eigen di bandingkan menggunakan metode STA yang lebih kompleks dengan menggunakan semua nilai eigen. Kata kunci: fisika kuantum, Landau Zener, fast forward, persamaan schrodinger, ,shorcut to adiabaticity

Abstract

Background: The rapid advancement of ICT (information and communication technology) during the Fourth Industrial Revolution offers great potential to transform physics learning, especially for abstract topics such as fluid matter. Limited laboratory facilities and suboptimal learning schedules in many schools can hinder students' understanding and cognitive learning outcomes.Objectives: This research seeks to: (1) ascertain the viability of the developed media, (2) measure the improvement in high school students' cognitive learning outcomes, and (3) determine students' responses to the learning media.Method: The ADDIE model (Analysis, Design, Development, Implementation, and Evaluation) was used in this research and development (R&D) study. The learning media developed was a 360° Virtual Reality video based on the Kuula platform integrated with ClassPoint. The trial was conducted on 39 eleventh-grade students utilizing a pretest-posttest approach in a single group. Data were collected through media and subject matter expert validation sheets, cognitive learning outcome tests, and questionnaires for student responses. Validation and student response data were subjected to descriptive and quantitatively analysis, while improvements in cognitive learning outcomes were analyzed using N-Gain scores.Results: Expert validation produced an average feasibility score of 90.16% (highly feasible). Students' cognitive learning outcomes improved significantly, with a high category N-Gain score of 0.83. The media received a highly favorable response from students, with an average score of 91.37% (very good).Conclusion: The virtual reality learning media based on the Kuula platform assisted by ClassPoint that was developed was declared highly feasible and effective in raising high school students’ cognitive learning outcomes on fluid material, particularly Archimedes' Principle. This media is an innovative alternative for schools with limited laboratory facilities.
