Pengembangan Perangkat Pembelajaran Inkuiri ditunjang Media Training Kit Pegasutan dan Pengereman Motor Listrik AC 3 Fasa Pada Mata Pelajaran Instalasi Motor Listrik di SMK Negeri 7 Surabaya

The Development of Inquiry Learning Devices is supported by the Media Training Kit for Starting and Braking of 3-Phase AC Electric Motors in the Subject of Electric Motor Installation at SMK Negeri 7 Surabaya

Penelitian ini bertujuan untuk mengetahui kelayakan perangkat pembelajaran yang dikembangkan. Kelayakan yang dimaksud dalam penelitian ini ialah kevalidan, keefektifan, dan kepraktisan. Perangkat pembelajaran yang dikembangkan meliputi rencana pelaksanaan pembelajaran (RPP), lembar eksperimen siswa, lembar penilaian (LP), media training kit pengasutan dan pengereman motor listrik AC 3 fasa. Langkah-langkah yang digunakan pada penelitian ini adalah menggunakan metode Research and Development (R&D) dengan one shot case study. Subjek uji coba pada penelitian ini adalah siswa kelas XI TITL 2 di SMKN 7 Surabaya. Hasil penelitian menunjukkan bahwa tingkat kevalidan diperoleh hasil sebagai berikut: (1) RPP IML mendapatkan rerata 3,85 diketegorikan sangat valid; (2) Lembar eksperimen siswa mendapatkan rerata 3,55 diketegorikan sangat valid; (3) LP sikap IML mendapatkan rerata 3,86 diketegorikan sangat valid; (4) LP pengetahuan IML mendapatkan rerata 3,76 diketegorikan sangat valid; (5) LP keterampilan IML mendapatkan rerata 3,63 dikategorikan sangat valid; (6) Training kit pengasutan dan pengereman motor listrik mendapatkan rerata 3,58 dikategorikan sangat valid. Dari perolehan hasil validasi diketahui tingkat kevalidan perangkat yang dikembangkan sangat valid. Tingkat keefektifan diperoleh hasil sebagai berikut: (1) hasil belajar ranah sikap mendapatkan dua hasil meliputi sikap spiritual mendapatkan rerata 87,50 dan sikap sosial mendapatkan rerata 85,50; (2) hasil belajar ranah pengetahuan yang diukur menggunakan tes uraian dan dianalisis menggunakan teknik one sample t-test. Dari analisis tersebut mendapatkan signifikansi 0,00, yang berarti nilai rerata siswa telah mencapai KKM dengan nilai rerata mencapai 85,66; (3) hasil belajar ranah keterampilan yang diukur menggunakan tes kinerja dan dianalisis menggunakan teknik one sample t-test. Dari analisis tersebut mendapatkan signifikansi 0,00, atau sangat signifikan yang berarti nilai rerata siswa telah mencapai KKM dengan nilai rerata mencapai 83,10. Dari tiga hasil belajar tersebut didapatkan rerata sebesar 85,44, menunjukkan tingkat keefektifan perangkat yang dikembangkan sangat efektif. Tingkat kepraktisan ditinjau dari keterlaksanaan pembelajaran melalui pengamatan guru TITL SMK Negeri 7 Surabaya mendapatkan rerata 3,70, menunjukkan bahwa perangkat pembelajaran sangat praktis. Hasil tersebut menunjukkan bahwa perangkat pembelajaran yang dikembangkan sangat layak untuk digunakan ditinjau dari 3 aspek yaitu aspek kevalidan, aspek keefektifan, aspek kepraktisan. Kata kunci: perangkat pembelajaran, kevalidan, keefektifan, kepraktisan.

This study aims to determine the feasibility of learning tools developed. The feasibility referred to in this study is validity, effectiveness, and practicality. The learning tools developed include learning implementation plans (RPP), student experiment sheets, assessment sheets (LP), training media kits for starting and braking a 3-phase AC electric motor. The steps used in this study are using the Research and Development (R&D) method with a one shot case study. The test subjects in this study were students of class XI TITL 2 at SMKN 7 Surabaya. The results showed that the level of validity obtained the following results: (1) RPP IML got an average of 3.85 which was categorized as very valid; (2) The students' experimental sheet gets an average of 3.55 which is categorized as very valid; (3) the IML attitude LP gets an average of 3.86 which is categorized as very valid; (4) LP knowledge of IML gets an average of 3.76 which is categorized as very valid; (5) the IML skills LP gets an average of 3.63 which is categorized as very valid; (6) The electric motor starting and braking training kit got an average of 3.58 which was categorized as very valid. From the acquisition of validation results, it is known that the level of validity of the developed device is very valid. The level of effectiveness obtained the following results: (1) learning outcomes in the attitude domain get two results including spiritual attitudes get an average of 87.50 and social attitudes get an average of 85.50; (2) learning outcomes in the domain of knowledge are measured using a description test and analyzed using the one sample t-test technique. From this analysis, a significance of 0.00 is obtained, which means that the average student score has reached the KKM with an average score of 85.66; (3) learning outcomes in the skills domain are measured using performance tests and analyzed using the one sample t-test technique. From this analysis, it is obtained a significance of 0.00, or very significant, which means that the average student score has reached the KKM with an average score of 83.10. From the three learning outcomes, an average of 85.44 was obtained, indicating the level of effectiveness of the developed device was very effective. The level of practicality in terms of the implementation of learning through the observation of TITL teachers at SMK Negeri 7 Surabaya obtained an average of 3.70, indicating that the learning device is very practical. These results indicate that the learning tools developed are very feasible to use in terms of 3 aspects, namely the validity aspect, the effectiveness aspect, the practicality aspect. Keywords: learning tools, validity, effectiveness, practicality.
