Pengembangan Aplikasi Animasi Laju Reaksi (Alare) untuk Melatihkan Kemampuan Berpikir Kritis Peserta Didik pada Materi Laju Reaksi

Development of Reaction Rate Animation Application (Alare) to Train Students' Critical Thinking Skills on Reaction Rate Material

Tujuan dari penelitian ini adalah menghasilkan aplikasi Alare yang layak digunakan untuk melatihkan kemampuan berpikir kritis peserta didik pada materi laju reaksi, khususnya pada sub materi faktor-faktor yang memengaruhi laju reaksi. Kelayakan aplikasi Alare ditinjau dari tiga aspek, yaitu kevalidan, kepraktisan, dan keefektifan. Jenis penelitian ini menggunakan metode Research and Development (R&D) dengan model pengembangan yang diadaptasi oleh Sukmadinata. Subjek penelitian ini berupa Aplikasi Alare yang diujicobakan kepada peserta didik kelas XI IPAS SMA Negeri 20 Surabaya yang telah mempelajari materi laju reaksi. Sumber data diperoleh dari instrumen penelitian berupa lembar telaah, lembar validasi, lembar angket respon peserta didik, lembar observasi, dan lembar tes. Data hasil penelitian menunjukkan bahwa (1) Aplikasi Alare dinyatakan valid ditinjau dari validitas isi dan validitas konstruk dengan memperoleh modus 4 dengan kategori valid, (2) Aplikasi Alare dinyatakan praktis ditunjukkan dengan hasil angket respon peserta didik mencapai rata-rata 89,20% tanggapan positif dan hasil observasi aktivitas peserta didik mencapai rata-rata 96,35% dengan kategori sangat baik, (3) Aplikasi Alare dinyatakan efektif berdasarkan hasil analisis data pretest dan posttest, diperoleh peningkatan kemampuan berpikir kritis peserta didik berdasarkan skor N-gain karena diperoleh kriteria medium-g dan high-g, serta ketuntasan hasil belajar peserta didik baik pada ketuntasan individu dan ketuntasan klasikal tuntas secara signifikan dengan persentase 100%. Disimpulkan bahwa aplikasi Alare layak digunakan untuk melatihkan kemampuan berpikir kritis peserta didik pada materi laju reaksi.

The purpose of this research is to produce an Alare application that is feasible to use to train students' critical thinking skills on reaction rate material, especially on the sub-material of factors that affect the reaction rate. The feasibility of the Alare application is reviewed from three aspects, namely validity, practicality, and effectiveness. This type of research uses the Research and Development (R&D) method with a development model adapted by Sukmadinata. The subject of this research is the Alare Application which was tested on students of class XI IPAS SMA Negeri 20 Surabaya who have studied reaction rate material. Data sources were obtained from research instruments in the form of review sheets, validation sheets, student respone questionnaires, observation sheets, and test sheets. The data from the results showed that (1) Alare application was declared valid in terms of content validity and construct validity by obtaining mode 4 with a valid category, (2) Alare application was declared practical as indicated by the results of the students' respone questionnaire reaching an average of 89.20% positive respones and the results of observations of students' activities reaching an average of 96.35% with a very good category, (3) Alare application is declared effective based on the results of pretest and posttest data analysis, obtained an increase in students' critical thinking skills based on the N-gain score because it obtained medium-g and high-g criteria, and the completeness of students' learning outcomes both in individual completeness and classical completeness is significantly complete with a percentage of 100%. It is concluded that the Alare application is feasible to train students' critical thinking skills on reaction rate material.
