Pengembangan Media Interaktif “Element Card” Berbasis Augmented Reality Pada Submateri Konfigurasi Elektron Menurut Niels Bohr

Development of Augmented Reality-Based Interactive “Element Card” Media on Electron Configuration Submaterial According to Niels Bohr

Penelitian ini bertujuan untuk mendapatkan kelayakan media interaktif Element Card berbasis Augmented Reality pada submateri konfigurasi elektron menurut teori Bohr. Penelitian ini menggunakan model 4D yang hanya dilakukan sampai tahap pengembangan. Penelitian ini dilaksanakan di SMAN 1 Gedangan Sidoarjo pada 30 peserta didik kelas X IPA. Penelitian ini menggunakan instrumen lembar validasi, soal pretest dan posttest, angket respon peserta didik, dan angket observasi peserta didik. Jika nilai hasil validasi ≥ 61% maka dianggap valid, nilai kepraktisan ≥ 61% maka dianggap praktis, dan nilai efektivitas jika tergolong di atas 0,3 yang termasuk sedang atau tinggi maka dianggap efektif . Hasil validasi isi dan konstruk sebesar 88% dan 84% termasuk dalam kategori sangat valid. Kepraktisan diperoleh dari 94,86% dan 97% tanggapan dan observasi peserta didik termasuk dalam sangat praktis. Keefektifan diperoleh dari hasil belajar dengan menghitung N-Gain dan Wilcoxon Signed Ranks Test, nilai Asymp. Sig (2 tailed) adalah 0,000 yang lebih kecil dari 0,05 sehingga terdapat perbedaan nilai pretest dan posttest peserta didik. Hal ini membuktikan bahwa media interaktif berbasis Augmented Reality Element Card dapat digunakan untuk media pembelajaran kimia.

This study aims to obtain the feasibility of Augmented Reality-based Element Card interactive media on the electron configuration submaterial according to Bohr's theory. This research uses a 4D model which is only carried out until the development stage. This research was conducted at SMAN 1 Gedangan Sidoarjo on 30 students X IPA. This study used a validation sheet instrument, pretest and posttest questions, student response questionnaires, and student observation questionnaires. If the value of the validation result is ≥ 61% then it is considered valid, the practicality value is ≥ 61% then it is considered practical, and the effectiveness value if it is classified above 0.3 which includes medium or high then it is considered effective. The results of content and construct validation are 88% and 84% are included in the very valid category. Practicality was obtained from 94.86% and 97% of student responses and observations included in the very practical. The effectiveness is obtained from learning outcomes by calculating the N-Gain and Wilcoxon Signed Ranks Test, the value of Asymp. Sig (2 tailed) is 0.000 which is smaller than 0.05 so there is a difference in the students' pretest and posttest scores. This proves that the interactive media based on the Augmented Reality Element Card can be used for chemistry learning media.
