Pengembangan E-LAPD untuk Melatihkan Kemampuan Analisis Peserta Didik Berorientasi Problem Based Learning pada Materi Kesetimbangan Kimia

Development of E-Worksheet to Train Students' Analysis Skills with Problem Based Learning Orientation on Chemical Equilibrium Material

Penelitian ini bertujuan untuk menghasilkan E-LAPD yang layak digunakan untuk melatihkan kemampuan analisis peserta didik berorientasi problem based learning pada materi kesetimbangan kimia. Kelayakan E-LAPD dapat ditinjau dari validitas, kepraktisan, dan keefektifan. Jenis penelitian yang digunakan adalah Research and Development dengan metode 4-D Tiagharajan yang terdiri dari langkah Define, Design, Develop, dan Disseminate. Data validitas didapatkan dari penilaian validator menggunakan lembar angket validasi. Data kepraktisan didapatkan dari angket respon peserta didik yang didukung dari hasil observasi aktivitas peserta didik. Data keefektifan didapatkan dari pre-test dan post-test kemampuan analisis dan kognitif yang diisi oleh peserta didik sebelum dan sesudah menggunakan E-LAPD yang dikembangkan. Hasil validitas menunjukkan  aspek komponen isi E-LAPD dinyatakan valid dengan modus 3, aspek kelayakan penyajian dinyatakan valid dengan modus 3. Hasil kepraktisan dinyatakan praktis karena mendapatkan persentase 86,44% dengan kriteria sangat baik didukung dengan hasil observasi aktivitas peserta didik. E-LAPD dinyatakan efektif berdasarkan hasil uji t dengan nilai signifikansi 0,00 yang berarti Ho ditolak dan Ha diterima. Berdasarkan hal tersebut, dapat disimpulkan bahwa E-LAPD layak untuk melatihkan kemampuan analisis peserta didik berorientasi problem based learning pada materi kesetimbangan kimia.

This research aims to produce an E-Worksheet that is suitable for use to train students' analytical skills oriented towards problem based learning on chemical equilibrium material. The feasibility of E-Worksheet can be reviewed from validity, practicality and effectiveness. The type of research used is Research and Development with the 4-D Tiagharajan method which consists of the Define, Design, Develop and Disseminate steps. Validity data is obtained from the validator's assessment using a validation questionnaire sheet. Practicality data was obtained from student response questionnaires which were supported by observations of student activities. Effectiveness data was obtained from the pre-test and post-test of analytical and cognitive abilities filled in by students before and after using the developed E-Worksheet. The validity results show that the E-Worksheet content component aspect is declared valid with mode 3, the feasibility aspect of presentation is declared valid with mode 3. The practical results were declared practical because they obtained a percentage of 86.44% with very good criteria supported by the results of observations of student activities. E-Worksheet was declared effective based on the results of the t test with a significance value of 0.00, which means Ho was rejected and Ha was accepted. Based on this, it can be concluded that E-LAPD is suitable for training students' analysis skills oriented towards problem based learning on chemical equilibrium material.
