Abstract

Semiconductor materials can be used as potential barriers to Tunnelling effects. In this study, four semiconductor materials are arranged in various ways to form a quadruple potential structure to analyze the value of the transmission coefficient. The analysis was conducted using the analytical and numerical matrix propagation method using Matlab2018a. The results confirmed that the inverted arrangement produces the same transmission coefficient value for each energy. So that there are 12 kinds of transmission coefficient values generated from 24 arrangements. The semiconductor material composition with the most considerable transmission coefficient value is ADCB and BCDA, which have a value of 0.8087. The variation of the arrangement affects the value of the transmission coefficient so that it can be used as a guideline for selecting the arrangement that produces the most optimum value of the transmission coefficient from various possible arrangements.

Abstract

ABSTRAKLesson study merupakan suatu model pengembangan kemampuan mengajar melalui pengkajian pembelajaran secara kolaboratif dan berkelanjutan. Lesson study dilaksanakan dalam tiga tahapan, yaitu plan, do, see yang dilaksanakan secara terstruktur, bersiklus dan berkelanjutan. Dalam penelitian ini subjek dari pelaksanaan lesson study adalah empat orang mahasiswa calon guru fisika yang sedang melaksanakan PPL di salah satu SMP Negeri di Bondowoso. Hasil penelitian menunjukkan bahwa penerapan lesson study dapat meningkatkan kemampuan mengajar mahasiswa calon guru fisika dari kriteria kurang baik menjadi kriteria sangat baik.ABSTRACTLesson study is a development model for educators through sustainable and collaborative learning. Lesson study was conducted in three phases, namely the plan, do, see phase, in which these phases were implemented in a structured, cyclical and continuous manner. In this study, the subject of lesson study implementation were four Physics pre- service conducted teaching practice in one of public junior high schools in Bondowoso. Results showed that lesson study implementation enhance these physics pre-service teachers teaching ability from poor to excellent.
