PENGEMBANGAN LEMBAR KERJA PESERTA DIDIK (LKPD) PADA MATERI RADIASI BENDA HITAM DENGAN BERBANTUAN PHET SIMULATIONS

DEVELOPMENT OF STUDENTS WORK SHEETS ON BLACK BODY RADIATION MATERIALS WITH PHET SIMULATIONS ASSISTED

Tujuan dari penelitian ini adalah untuk mengetahui kevalidan, kepraktisan, dan keefektifan Lembar kerja peserta didik (LKPD) pada materi Radiasi Benda Hitam dengan berbantuan PhET simulations. Metode penelitiannya adalah Penelitian dan Pengembangan dengan model ADDIE (Analysis, Design, Development, Implementation, Evaluation). Subjek penilitian yaitu 15 peserta didik pada kelas XII MIA 5 di MAN 1 Lamongan tahun pelajaran 2020/2021 pada semester genap. Hasil validasi perangkat pembelajaran Lembar kerja peserta didik (LKPD) dari para ahli telah memenuhi standart dinama persentase kelayakan isi sebesar 89.30%, persentase kebahasaan sebesar 93,30%, persentase sajian sebesar 92%, dan persentase kegrafisan sebesar 95%. Hasil persentase tiap poin dari tiga validator menunjukkan bahwa Lembar kerja peserta didik (LKPD) yang telah dibuat termasuk dalam kategori sangat valid. Hal tersebut didukung oleh hasil respon peserta didik melalui angket yang dibagikan mengenai Lembar kerja peserta didik (LKPD) dinama persentasenya sebesar 84,44% yang termasuk dalam kategori sangat baik. Hasil evaluasi peserta didik setelah pembelajaran menggunakan Lembar kerja peserta didik (LKPD) menunjukkan bahwa 87% peserta didik tuntas dan 13% peserta didik tidak tuntas. Sehingga dapat disimpulkan bahwa Lembar kerja peserta didik (LKPD) yang dibuat telah valid dengan respon peserta didik yang sangat baik dan efektif untuk meningkatkan pemahaman peserta didik mengenai materi Radiasi Benda Hitam.

The aims of this study was to determine the validity, practicality, and effectiveness of student worksheets on Black Body Radiation with the PhET simulations. The research method used is Research and Development with the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). The research subjects were 15 students of class XII MIA 5 in MAN 1 Lamongan for the 2020/2021 school year in the even semester. The results of the validation of the learning tools student worksheets from the experts have met the standard, namely the percentage of content eligibility is 89,30%, the percentage of language is 93,30%, the percentage of presentation is 92%, and the percentage of graphic is 95%. The result  of the percentage of each point from the three validators shows that student worksheets that have been made are included in the very valid category. This is supported by the result of student responses through questionnaires distributed about student worksheets in which the percentage is 84,44% which is included in the very good category. The result of the evaluation of students after learning using student worksheets showed that 87% of students completed and 13% of students did not completed. So, it can be concluded that the student worksheets that were made were valid with excellent and effective students responses to improve students understanding of black body radiation material.
