KELAYAKAN LKPD-E BERORIENTASI KETERAMPILAN PROSES SAINS BERBANTUAN LIVEWORKSHEETS PADA SUB MATERI FAKTOR PERGESERAN ARAH KESETIMBANGAN KIMIA KELAS XI SMA

FEASIBILITY OF LIVEWORKSHEETS ASSISTED ELECTRONIC STUDENTS' WORKSHEET ON SUB-MATERIAL FACTOR SHIFTS IN THE DIRECTION OF CHEMICAL EQUILIBRIUM FOR CLASS XI HIGH SCHOOL

Penelitian pengembangan ini bertujuan untuk mendeskripsikan kelayakan Lembar Kerja Peserta Didik Elektronik (LKPD-E) berorientasi keterampilan proses sains berbantuan liveworksheets pada sub materi faktor pergeseran arah kesetimbangan kimia. Kelayakan LKPD-E ditinjau dari segi validitas, kepraktisan, dan keefektifan. Penelitian ini menggunakan metode Research and Development (R&D) dengan model Borg & Gall. Penelitian ini dibatasi hanya sampai tahap uji coba terbatas. Uji coba terbatas dilakukan di SMA Negeri 20 Surabaya pada 27 peserta didik kelas XI MIPA 6 yang sebelumnya sudah mendapatkan materi kesetimbangan kimia. LKPD-E berorientasi keterampilan proses sains berbantuan liveworksheets ini dinyatakan layak. Ditinjau berdasarkan validitas isi dan konstruk, didapatkan modus 5 dengan kategori sangat valid. Ditinjau dari segi kepraktisan, berdasarkan respon peserta didik pada kriteria isi, penyajian, kebahasaan, kegrafikan, dan keterampilan proses sains mendapatkan persentase secara berturut-turut sebesar 93,1%; 83,72%; 95,07%; 95,07%; dan 90,29% yang termasuk dalam kategori sangat praktis, serta didukung oleh hasil observasi aktivitas peserta didik yang relevan lebih dominan dibandingkan dengan aktivitas tidak relevan. Ditinjau dari segi keefektifan, didapatkan hasil berdasarkan uji one sample t-test nilai pretest dan posttest ranah keterampilan proses sains bahwa t_hitung sebesar 48,53, t_tabel sebesar 1,706 yang artinya rata-rata nilai posttest lebih besar dari rata-rata nilai pretest. Berdasarkan hasil uji kecocokan Chi Square memperoleh nilai 𝑥²_hitung ≥ 𝑥²_tabel, dengan 𝑥²_hitung sebesar 12,343 yang berarti terdapat kecocokan antara level keterampilan proses sains posttest dengan level keterampilan proses sains LKPD-E, serta didukung oleh ketuntasan klasikal hasil belajar ranah pengetahuan sebesar 92,59%.

This development research aims to describe the feasibility of Electronic Student Worksheets (LKPD-E) oriented to science process skills assisted by liveworksheets on the sub-material of shifting factors towards chemical equilibrium. LKPD-E feasibility in terms of validity, practicality, and effectiveness. This study used research and development (R&D) methods using the Borg & Gall model. This research is limited to limited trials. A limited trial was conducted at SMA Negeri 20 Surabaya on 27 students in class XI MIPA 6 who had previously received material on chemical equilibrium. LKPD-E, oriented to science process skills assisted by live worksheets, is declared feasible. When reviewed based on content and construct validity, Mode 5 is a very valid category. In terms of practicality, based on student responses to the criteria for content, presentation, language, graphics, and science process skills, the percentages respectively were 93.1%; 83.72%; 95.07%; 95.07%; and 90.29% which is included in the very practical category, and is supported by the results of observations of relevant student activities that are more dominant than irrelevant activities. When viewed from the aspect of effectiveness, the results obtained based on the one sample t-test values of pretest and posttest in the realm of science process skills show that t_count is 48,53, t_table is 1.706, which means there was an increase in posttest results compared to the pretest average. The results of the Chi Square fit test obtained the value 𝑥²_count ≥ 𝑥²_table, with 𝑥²_count of 12,343 which means there is a match between the posttest science process skills level and the E-LKPD science process skills level and is supported by the classical mastery of learning outcomes in the realm of knowledge of 92.59%.

Keywords: E-LKPD, science process skills, chemical equilibrium shifting factor, feasibility of E-LKPD.
