Tujuan penelitian ini adalah untuk membuat perangkat pembelajaran yang layak dengan menerapkan model pembelajaran project based learning (PjBL) berbantuan software EKTS pada mata pelajaran instalasi motor listrik dengan mengacu pada indikator kelayakan yaitu kevalidan, kepraktisan dan keefektifan.

Penelitian ini merupakan penelitian pengembangan dengan menggunakan model Research and Development (R&D) yang dilakukan melalui 4 tahap. Masing masing tahap adalah tahap studi pendahuluan, tahap merancang perangkat pembelajaran, tahap validasi dan revisi, dan tahap uji coba empiris dan revisi. Pada penelitian ini rancangan uji coba yang digunakan adalah pretest-posttest desain.

Hasil kevalidan perangkat pembelajaran PjBL IML berbantuan software EKTS meliputi hasil validasi pada silabus PjBL IML memiliki kriteria sebesar 91.96%, hasil validasi pada RPP PjBL IML memiliki kriteria sebesar 92.2%, hasil validasi pada bahan ajar PjBL IML memiliki kriteria sebesar 89.16%, hasil validasi pada LKPD PjBL IML memiliki kriteria sebesar 91.17%, hasil validasi pada lembar keterlaksanaan pembelajaran PjBL IML memiliki kriteria sebesar 88.5%, hasil validasi pada lembar angket respon peserta didik PjBL IML memiliki kriteria sebesar 88.5%, hasil validasi pada lembar observasi kompetensi peserta didik ranah sikap IML memiliki kriteria sebesar 92.5%, hasil validasi pada tes kompetensi peserta didik ranah pengetahuan IML memiliki kriteria sebesar 90.15%, hasil validasi pada lembar observasi kompetensi peserta didik ranah keterampilan IML memiliki kriteria sebesar 92.5%, dan hasil validasi pada tes kompetensi pemecahan masalah peserta didik IML memiliki kriteria sebesar 91.6%.

Hasil kepraktisan perangkat pembelajaran PjBL IML berbantuan software EKTS meliputi keterlaksanaan pembelajaran PjBL IML memiliki nilai hasil rating yakni sebesar 90.8% dengan kategori sangat layak, dan respon peserta didik PjBL IML mendapat penilaian rata-rata total seluruh aspek 77.4% dengan kategori baik.

Hasil keefektifan perangkat pembelajaran PjBL IML berbantuan software EKTS meliputi kompetensi peserta didik ranah sikap IML dikagetorikan sangat baik dengan skor rata-rata di atas KKM (75). Kompetensi peserta didik ranah pengetahuan IML diperoleh dari uji one sample t-test mendapatkan hasil di atas KKM (75), dan dari uji paired sample t-test menyatakan terdapat pebedaan kompetensi peserta didik ranah pengetahuan IML sebelum dan sesudah diberikan pembelajaran menggunakan perangkat pembelajaran PjBL IML berbantuan software EKTS. Kompetensi peserta didik ranah keterampilan IML diperoleh dari uji one sample t-test­ dengan hasil nilai pencapaian di atas KKM (75). Pemecahan masalah peserta didik IML diperoleh dari uji one sample t-test  mendapat hasil pencapaian di atas KKM (75).

This research aims to create a feasible learning tool by applying the learning model project based learning (PjBL) assisted by EKTS software  in electric motor installation subjects by referring to the feasibility indicators namely validity, practicality and effectiveness.

This research is a development research by using Research and Development (R&D) through 4 stages. The first stage is a preliminary study. The second stage is designing the learning tools. The third stage are validation and revision. The fourth stage are empirical testing and revision. In this study the experimental design used was a pretest-posttest design. 

The validity results of the IML PjBL learning tool assisted by the EKTS software  include the results of the IML PjBL syllabus having a criteria of 91.96%, the results of the validation on the implementation plan of the IML PjBL learning have a 92.2% criterion, the validation results on the IML PjBL teaching materials have a criteria of 89.16%, the results of the validation on the implementation plan of the IML validation on PjBL IML LKPD has a criterion of 91.17%, the results of the validation on the PjBL IML learning achievement sheet have a criteria of 88.5%, the results of the validation on the questionnaire sheet of responses of PjBL IML students have a 88.5% criterion, the results of the validation on the student competency observation sheet are 88.5% IML attitude has a criteria of 92.5%, the results of the validation on the competency test of students of the IML knowledge domain have criteria of 90.15%, the results of the validation on the competency observation sheet of the IML skills students have a criterion of 92.5%, and the results of the validation on the competency test of problem solving participants IML students have the criteria is 91.6%.

The practicality results of the IML PjBL learning tool assisted by EKTS software  include the implementation of the IML PjBL learning that has a rating value of 90.8% with a very decent category, and the response of the PjBL IML students gets an average assessment of the total aspects of all 77.4% with a good category.

The results of the effectiveness of the IML PjBL learning tool assisted by EKTS software  include the competence of students in the IML attitude domain are rated very well with an average score above the KKM (75). IML knowledge domain students' competencies were obtained from the one sample t-test to get results above the KKM (75), and from the paired sample t-test test stated that there were differences in the IML knowledge domain competencies of students before and after learning using IML PjBL learning tools.assisted EKTS software. Competence of learners realm IML skills gained from test one sample t-test with the results of the achievement of the above KKM (75). Problem solving for IML students is obtained from the one sample t-test, the results obtained are above the KKM (75).
