Abstract

Purpose- This study aims to design and test student worksheets (LKPD) using simple water wheel media, and to cultivate an environmental care attitude among junior high school students.Methodology- This research is a Research and Development (R&D) with the 4-D model (define, design, develop, disseminate). This research was carried out at SMP IT Ibnu Abbas with 34 students of eighth grade as participants. The data collection is done using the pre-test, post-test, and environmental care attitude questionnaire.Findings-Validation analysis reveals a predominant average score of 94% (very valid category) towards the suitability of worksheets for instilling the attitude of environmental care and its advantage in the science subject as determined from teacher and student questionnaires. The outcomes showed that there was an effect of simple water wheel media on students' attitude to care for environment and conceptual understanding, average gained N-gain = 0.86 (in the high category).Significance- This study shows how innovative, hands-on media have the potential to support science education and promote students’ sense of responsibility for environmental sustainability.Keywords: Environmental Care Attitudes, Student Worksheet, Water wheel

Abstract

Penelitian ini bertujuan untuk memperlihatkan dalam tampilan grafik nilai fungsi gelombang untuk potensial non sentral Coulombic Rosen Morse menggunakan metode numerik beda hingga. Metode numerik beda hingga menggunakan persamaan Schrodinger dan persamaan diferensial biasa orde II untuk mendapatkan persamaan pendekatan numerik. Persamaan pendekatan numerik kemudian dikerjakan dalam matriks dan dilakukan substitusi balik sehingga didapatkan fungsi gelombang bagian radial dan angular yang divisualisasikan dengan pemrograman komputer berbasis Matlab. Visualisasi fungsi gelombang radial yang terbentuk mendiskripsikan nilai probabilitas ditemukannya elektron pada suatu atom, sedangkan Visualisasi fungsi gelombang angular yang terbentuk memperlihatkan gerakan suatu elektron dalam suatu tingkat energi.
