Pengembangan e-LKPD Inkuiri Terbimbing Berorientasi Multipel Representasi Kimia untuk Melatihkan Keterampilan Proses Sains Peserta Didik pada Materi Kesetimbangan Kimia

Development of Guided Inquiry e-LKPD Oriented with Multiple Chemical Representations to Train Students Science Process Skills on Chemical Equilibrium Material

Tujuan penelitian ini yaitu untuk menghasilkan produk berupa e-LKPD yang layak pada materi kesetimbangan kimia. Metode yang digunakan yaitu penelitian dan pengembangan dengan model 4D yang terdiri dari define, design, develop, dan disseminate. Penelitian ini hanya dilakukan hingga tahap pengembangan. E-LKPD pada materi kesetimbangan kimia diujicobakan kepada peserta didik kelas XI-5 SMA Negeri 3 Surabaya yang telah mempelajari materi kesetimbangan kimia merupakan subjek penelitian ini. Sumber data diperoleh dari instrumen penelitian berupa lembar telaah, lembar validasi, lembar angket respon peserta didik, lembar observasi, lembar tes. Teknik pengumpulan data penelitian ini dengan metode angket, observasi, dan tes. Penelitian ini dianalisis menggunakan uji N-gain dan Uji Paired Sample T-Test. Hasil validasi e-LKPD dari aspek validitas isi dan validitas konstruk, masing-masing memperoleh modus sebesar 4 sehingga sangat valid untuk digunakan. Hasil angket respon peserta didik mencapai rata-rata 88,3% tanggapan positif dengan kategori sangat praktis. Hasil analisis data pretest dan posttest diperoleh peningkatan kemampuan proses sains ditunjukkan dengan 80% peserta didik memperoleh skor N-gain ≥ 0,7 dan berdasarkan uji paired sample t-test diperoleh nilai P-Value sebesar 0,000 (< 0,05) serta peningkatan hasil belajar ranah kognitif ditunjukkan dengan 65% peserta didik memperoleh skor N-gain ≥ 0,7, sehingga dinyatakan efektif untuk digunakan. Disimpulkan bahwa e-LKPD Inkuiri Terbimbing Berorientasi Multipel Representasi Kimia pada materi kesetimbangan kimia layak digunakan untuk melatihkan keterampilan proses sains dan pemahaman konsep peserta didik. 

The purpose of this research is to produce a product in the form of a feasible e-LKPD on chemical equilibrium material. The method used is research and development with the 4D model consisting of define, design, develop, and disseminate. This research was only conducted up to the development stage. E-LKPD on chemical equilibrium material was tested on students of class XI-5 SMA Negeri 3 Surabaya who had studied chemical equilibrium material was the subject of this study. Data sources were obtained from research instruments in the form of review sheets, validation sheets, student response questionnaires, observation sheets, test sheets. The data collection technique of this research was using questionnaire, observation, and test methods. This research was analyzed using the N-gain test and the Paired Sample T-Test test. The results of e-LKPD validation from the aspects of content validity and construct validity, each obtained a mode of 4 so that it is very valid to use. The results of the learner response questionnaire reached an average of 88.3% positive response with a very practical category. The results of pretest and posttest data analysis obtained an increase in science process skills indicated by 80% of students obtaining an N-gain score ≥ 0.7 and based on the paired sample t-test obtained a P-value of 0.000 (<0.05) as well as an increase in cognitive learning outcomes indicated by 65% of students obtaining an N-gain score ≥ 0.7, so that it is declared effective to use. It is concluded that the Guided Inquiry e-LKPD Oriented to Multiple Chemical Representations on chemical equilibrium material is feasible to use to train students' science process skills and concept understanding.
