Abstract

Abstrak

Tujuan penelitian ini untuk: (1) Mengembangkan bahan ajar jobsheet pada mata pelajaran kerja bengkel gambar teknik pada kelas X Elektronika di SMK Muhammadiyah Prambanan dan (2) Menguji kelayakan bahan ajar jobsheet  mata pelajaran kerja bengkel gambar teknik pada ahli materi, ahli media dan responden. Penelitian ini menggunakan 4D Models yaitu (1) Define, (2) Design, (3) Develop, (4) Disseminate. Metode pengumpulan data melibatkan validator ahli materi dan ahli media. Uji kelayakan produk dilakukan kepada siswa kelas X Elektronika di SMK Muhammadiyah Prambanan. Pengumpulan data menggunakan angket skala Likert-4. Validitas instrumen yang  digunakan  berdasarkan  pendapat  para  ahli,  sedangkan  reliabilitas  menggunakan  rumus  Alpha,  dengan

perolehan nilai r11 sebesar 0.97 masuk dalam kategori reliabilitas sangat tinggi. Teknik analisis data menggunakan analisis deskriptif. Hasil pengembangan menunjukkan bahwa bahan ajar mata pelajaran kerja bengkel gambar teknik mendapatkan penilaian kelayakan dari validator ahli materi sebesar 74% dengan kategori Layak, penilaian

kelayakan dari validator ahli media sebesar 88% dengan kategori Sangat Layak, dan penilaian kelayakan dari responden (siswa) sebesar 90% dengan kategori Sangat Layak. Hal ini menunjukkan bahwa jobsheet kerja bengkel

gambar teknik layak.

Abstract

The purposes of this research were to develop learning materials in form of jobsheet for practical

engineering in drawing workshop of industrical electrical engineering student of class X at Muhammadiyah Prambanan Vocational School and to test the feasibility learning materials according to subject matter experts, media experts, and respondents. The research used 4D method which consisted of Define, Design, Develop, and Disseminate. The method for data collection based on assessment from two subject matter experts’ validation and two media experts’ validation. Instrument for data collecting was a Likert-4 scale questionnare. The instrument was validated by experts, while reliability of instrument used an Alpha formula, that gained r11 values of 0.97 and categorized as highly reliable. Data analysis used descriptive analysis. The result of this research showed that learning materials for practical engineering in drawing workshop obtained the feasibility assessment of subject matter experts on 74% categorized as feasible, the feasibility assessment of media experts on 88% categorized as highly feasible and the feasibility assessment of respondents (students) 90% categorized as highly feasible. This suggested that the jobsheet for practical engineering in drawing workshop was feasible.
