Abstract

Bound state solution of Dirac Equation for trigonometric Scarf potential with a new tensor coupling under spin and pseudospin symmetric limits are investigated using Nikiforov-Uvarov method. The new tensor potential proposed is inspired by superpotential form in SUSY quantum mechanics. The Dirac equation with trigonometric Scarf potential coupled by new tensor potential for the pseudospin and spin symmetric cases reduces to Schrodinger type equation with shape invariant potential since the proposed new potentials are similar to the superpotential of Scarf potential. The relativistic wave functions are exactly obtained eigenfunction of NU method in terms of Jacobi polynomials and the relativistic energy equation is exactly obtained by using eigenvalue of NU method in the approximation scheme of centrifugal term. The new tensor potential omits the energy degeneracy both for pseudospin and spin symmetric cases. Keywords: Scarf potential, new tensor coupling potential, spin and pseudospin symmetry, Nikiforov-Uvarof methods.

Abstract

This study intended to describe the effectiveness of the GEM-CL learning model selaras Bakar Batu cultural practice on chapter heat and temperature. This type of research was quasi-experiment with pretest and post-test control group design. The study population was all students of class XI IPA SMAN 1 Jayapura. The sampling technique used was simple random sampling. The selected classes were XI IPA-3 as an experimental class and class XI IPA-5 as a control class. Data collection instruments were tests based on higher-order thinking skills and questionnaires to collect students’ responses. Data analysis was done by t-test, N-gain, and effect size for data collecting from test data while data from questionnaires were analyzed by descriptive qualitative analysis. It was concluded that the model is effective to apply in physics learning to preserve students’ conceptual understanding and improve students’ higher-order thinking skills. Further study on GEM-CL to other cultural practices and physics chapter in Indonesia would would strengthen this learning model.
