Many factors influence the low number of skilled vocational high school graduates. One factor that is the leading cause is the lack of instruments that can be used in the learning process, especially authentic instruments, to assess students' abilities in the psychomotor domain. Students who are dominant in the cognitive sphere are not necessarily skilled in the psychomotor realm, especially when using the equipment and making improvements to the brake system. The purpose of this study is to develop an assessment instrument that is appropriate to be used by the teacher in evaluating the psychomotor domain's abilities, specifically for the brake system competency. This research is development research that uses ADDIE models as a reference for research. ADDIE model has five stages of development that need to be considered, including analysis; (2) design; (3) development; (4) implementations; and (5) evaluation. Based on the results of the analysis and discussion of the psychomotor domain assessment instrument for the competency of the brake system that was developed to be suitable for use in the learning process. Feasibility is proven from the results of the validation of experts who get an assessment of 4.66 with a very valid category. The instrument reliability test results that get the Cronbach's alpha value of 0.895, and the value of inter-observer reliability is 0.740. In addition, the instrument is also practical when used in the learning process. This was evidenced by the acquisition of practicality test value of 3.31 and entered in the practical category.
Many factors influence Students' low abilities in the affective domain, especially at the level of vocational schools (VHS). The lack of ability of teachers to develop affective authentic assessment instruments be one of the factors that influence it. Besides, designing authentic assessment instruments is not as easy affective cognitive assessment. This research uses ADDIE development model as a reference in developing affective authentic assessment instruments. There are five stages of ADDIE models, include analysis; (2) design; (3) development; (4) implementations; and (5) evaluation. Based on data analysis is known that instruments developed are valid, reliable, and practical to use in the learning process. This is evidenced from (1) the results of the validation by 4, 50 with a valid category; (2) the reliability test results amounted to 0.985 with a special category; and (3) test results practicality of 3.06 with a practical category.
<p>Penelitian ini bertujuan untuk: 1) mengetahui validitas media pembelajaran yang dikembangkan berupa media pembelajaran kit <em>Robot Transporter</em>, 2) mengetahui respon mahasiswa selama penerapan media pembelajaran yang dikembangkan, 3) mengetahui hasil belajar mahasiswa setelah penerapan media pembelajaran yang dikembangkan, 4) mengetahui keterlaksanaan media pembelajaran yang dikembangkan. Jenis penelitian yang digunakan dalam penelitian ini adalah penelitian pengembangan dengan menggunakan model 4-D. Untuk uji coba produk menggunakan <em>one group pretest-posttest design </em>yaitu membandingkan nilai <em>pretest </em>dan <em>posttest</em>. Nilai <em>pretest </em>diperoleh sebelum pembelajaran dengan menggunakan robot transporter dan nilai posttest diperoleh setelah pembelajaran. Dalam penelitian ini diperoleh data hasil validasi media pembelajaran sebesar 88,67% dan dikategorikan sangat layak untuk digunakan. Untuk hasil validasi butir soal diperoleh skor 86,62% dan dikategorikan sangat layak untuk digunakan. Sedangankan untuk tes hasil belajar diperoleh nilai rata-rata pretest 35,63 dan 85 untuk nilai rata-rata posttest. Hasil respon mahasiswa terhadap media –robot <em>transporter </em>diperoleh skor rata-rata sebesar 88% dan dikategorikan sangat baik maka media robot <em>transporter </em>layak digunakan dalam proses pembelajaran. Keterlaksanaan pembelajaran menunjukan hasil skor 4,6 dan masuk dalam kategori sangat baik, sehingga media robot transporter dalam proses kegiatan belajar mengajar bisa terlaksana dengan baik.</p>
