PENGEMBANGAN MEDIA PEMBELAJARAN SISTEM BILANGAN BINER PADA MATA PELAJARAN PRAKTIK DIGITAL DI SMK N 1 PUNDONG

Abstract

Abstrak

Penelitian ini bertujuan untuk: (1) merancang bangun (desain) dan mengetahui fungsionalitas trainer kit sistem bilangan biner yang layak pada mata pelajaran praktik digital, (2) mengetahui kelayakan trainer kit sistem bilangan biner ditinjau dari ahli media, ahli materi dan pengguna pada mata pelajaran praktik digital. Penelitian ini merupakan jenis penelitian dan pengembangan (research and development). Model pengembangan produk mengadaptasi model pengembangan ADDIE yang dikembangkan oleh Robert Maribe Branch yaitu: analisis, perancangan, pengembangan, implementasi, dan evaluasi. Hasil penelitian ini adalah: (1) berupa produk trainer kit sistem bilangan biner berbasis mikrokontroler ATMega 32 yang dapat digunakan untuk mengkonversi nilai biner ke desimal kemudian menampilkan hasil konversi pada display LCD dan trainer kit sistem bilangan biner dapat berfungsi sangat baik dengan persentase sebesar 91,07% yang diperoleh melalui data angket ahli media pada aspek pengoperasian; (3) kelayakan media pembelajaran trainer kit sistem bilangan biner, berdasarkan penilaian ahli media diperoleh persentase 87,06% atau dalam kategori “sangat layak”, berdasarkan penilaian ahli materi diperoleh persentase 84,00% atau dalam kategori “layak”, penilaian pengguna pertama (guru) diperoleh persentase 99% atau dalam kategori “sangat layak”, dan penilaian pengguna terakhir (siswa) diperoleh persentase 80,83% atau dalam kategori “layak”.

Abstract

This research aims to: (1) designing model and knowing the function trainer kit of binary numeral which is appropriate for digital practical subject,(2) finding out the feasibility of the trainer kit of binary numeral which is observed by the media experts, materials experts and the users from the digital practical subject it self. This research is the kind of research and development. The model of the product development is adapted from the ADDIE model of development developed by Robert Maribe Branch, namely: analyze, design, develop, implement, and evaluate. The results of this study are: (1) ATMega microcontroller 32 –based product trainer kit of binary numeral can be used to convert the binary number to a decimal and displays the results of the conversion in the LCD display and the trainer kit binary of numeral can function very well with the percentage of 91.07% which is obtained through questionnaire form from media experts in the operation aspects; (2) the feasibility of the learning media trainer kit of binary numeral reaches the percentage to 87.06% or in the category of "highly-feasible" from the media experts judgment, 84.00% from the materials expert judgment, or in the category of "feasible", 95.25% from the evaluation of the first users (teachers) or in the category of "highly- feasible", and 80.83% from the evaluation of the end users (students) or in the category of "feasible".

Keywords:  trainer kit of binary numeral, the conversion from binary number to decimal, ATMega microcontroller 32
