Abstract

The relativistic energy and wave function for the hyperbolic Manning Rosen potential with Coulomb-type tensor potential in the case of pseudospin symmetry are obtained from solving the Dirac equation using the Romanovski polynomial method. Using the appropriate wave function and variable substitution to reduce the second-order differential equation to a hypergeometric-type equation, the Dirac equation can be solved using Romanovski polynomials. The relativistic energy equation and weight function for Romanovski polynomials are produced by comparing the standard differential and hypergeometric type equations. Relativistic energy can be determined by employing numerical techniques and Matlab software to solve the relativistic energy equation. The weight function yields the relativistic wave function, which is then represented for the lower component of Dirac spin in the form of Romanovski polynomials

Abstract

This research aims to determine the effectiveness and response of students to the Student Worksheet (LKPD) that was developed. The type of research is research and development with a "one group pretest-posttest design". Population in this research were class VIII students at SMP 3 Selong. The instruments used are interview sheets, observation sheets, product validation, student response questionnaire sheets, teacher response questionnaire sheets, learning device validation sheets, evaluation question sheets. The research results were analyzed using the method quantitative descriptive. The results of the analysis of pre-test and post-test evaluation questions increased, showing an average N-gain 0.70 with an average pre-test score of 23.97 and an average post-test score of 81.47. The t test results show that t calculated > t (0.05)(66), namely 30.40 > 1.66. This indicates that Problem Base Learning (PBL) based LKPD is effective in improving students' physics learning outcomes.
