Based on the results of the three tests it can be concluded that the learning module is suitable for use in the learning process. While the module practicality test by students obtained an average value of 87%, so it is in a very practical category. In the module practicality test by the teacher obtained an average value of 85.83%, so it is in the practical category. In the module reliability test the Cronbach Alpha value was 0.804, which means the reliability of the module in the category is very high. Tentukan variasi harga RL (min dan max) agar te- gangan output masih stabil 10 Volt. Based on the results of 3 validators obtained an average of 0.82 from the rating scale 1, which exceeds the achievement level of 0.667, so the module is declared valid. Rangkaian Dioda Contoh 2.1: Rangkaian penyetabil tegangan seperti gambar 2.10 mempunyai data sbb: Vi 50 Volt, Rs 1 K, Vz 10 Volt, dan Izm 32 mA. The research instruments were in the form of questionnaires on validity, reliability and practicality of the module. Elektronika merupakan ilmu yang mempelajari alat listrik arus lemah yang dioperasikan dengan cara mengontrol aliran elektron atau partikel bermuatan listrik dalam suatu alat seperti komputer, peralatan elektronik, termokopel, semikonduktor, dan lain sebagainya. This research method uses the development of Instructional Development Institute with three stages, namely define, development, and evaluation. The purpose of this study was to determine the feasibility of using the learning module of the Electronic Electronics Series on the subject of Basic Electricity and Electronics in class X Electronics Engineering at SMK Negeri 1 Bukittinggi. 1 JOB SHEET PRAKTIKUM TEI PRAKTIKUM RANGKAIAN ELEKTRONIKA TEKNIK ELEKTRO INDUSTRI (D - 4) LABORATORIUM PENGUKURAN LISTRIK JURUSAN TEKNIK ELEKTRO FAKUL.
