PENGEMBANGAN LKPD BERBASIS INKUIRI UNTUK MENINGKATKAN KETERAMPILAN HOTS PADA MATERI LAJU REAKSI 

Development of Inquiry-based Student Worksheet to Improve High Order Thinking Skill on Reaction Rates

Tujuan penelitian ini adalah untuk mengetahui kelayakan (kevalidan, kepraktisan dan keefektifan) Lembar Kerja Peserta Didik (LKPD) berbasis inkuiri untuk meningkatkan keterampilan berpikir tingkat tinggi (HOTS) pada materi laju reaksi. Penelitian ini dikembangkan menggunakan metode 4D (define, design, develop, dissiminate), namun hanya sampai tahap pengembangan (develop) yang diuji cobakan terbatas pada 15 peserta didik SMA Muhammadiyah 10 GKB Gresik yang sudah mendapatkan materi laju reaksi. Instrumen penelitian yang digunakan yakni lembar validasi, lembar angket respon, lembar tes ranah kognitif dan lembar tes keterampilan HOTS yang dianalisis menggunakan deskriptif kuantitatif. Hasil penelitian menunjukkan tingkat kevalidan LKPD sangat valid dengan persentase kesesuaian isi 93%, kebahasaan 91%, penyajian 92% dan kegrafisan 88%. Respon peserta didik menunjukkan kategori sangat praktis dengan rata-rata presentase 90,5%. Hasil tes ranah kognitif memperoleh skor N-gain dengan kategori tinggi sebesar 0,88. Hasil tes ranah keterampilan HOTS tiap komponen C4, C5 dan C6 memperoleh nilai rata-rata presentase berturut-turut sebesar 87%, 85,8%, 86,6%. Selain itu, hasil tes ranah keterampilan HOTS dibuktikan menggunakan uji paired sample t test dan mendapatkan nilai signifikansi sebesar 0 sehingga dapat disimpulan bahwa LKPD berbasis inkuiri dapat meningkatkan keterampilan HOTS pada submateri faktor yang mempengaruhi laju reaksi.

The research purpose is to determine the feasibility of an inquiry-based Student Worksheet (LKPD) to improve higher order thinking skills (HOTS) on the reaction rate material. This research was developed using the 4D method (define, design, develop, disseminate), but only up to the development stage, which was tested on a limited basis on 15 students of SMA Muhammadiyah 10 GKB Gresik who had received reaction rate material. The research instruments used were validation sheets, response questionnaire sheets, cognitive domain test sheets and HOTS skills test sheets which were analyzed using quantitative descriptive. The results showed that the LKPD level of validity was very valid with the percentage of content conformity 93%, linguistics 91%, presentation 92% and graphics 88%. The response of the students showed a very practise category with an average percentage of 87%. The results of the cognitive domain test obtained an N-gain score of 0.88 in the high category. The results of the HOTS skills test results C4, C5 and C6 obtained an average percentage score of 87%, 85.8%, 86.6%, respectively. In addition, the results of the HOTS skill domain test were proven more clearly using paired t-tests and got a significance value of 0 so it can be concluded that inquiry-based worksheets can improve HOTS skills on the submaterial factors that affect reaction rates.
