Pengembangan Media Pembelajaran Berbasis Website pada Materi Laju Reaksi untuk Meningkatkan Hasil Belajar Peserta Didik

Development of Website-Based Learning Media on Reaction Rate Material to Improve Student Learning Outcomes

Penelitian pengembangan ini bertujuan untuk mendeskripsikan kelayakan media pembelajaran berbasis website untuk materi laju reaksi. Kelayakan media pembelajaran ditinjau dari segi kevalidan, kepraktisan, dan keefektifan. Kevalidan media diukur dengan validitas isi dan validitas konstruk. Kepraktisan media diukur dari respon dan aktivitas peserta didik. Keefektifan media diukur dari persentase ketuntasan klasikal dan peningkatan hasil belajar peserta didik. Metode penelitian yang digunakan dalam penelitian ini adalah metode Research and Development (R&D) Borg and Gall yang telah dimodifikasi oleh Sukmadinata. Uji coba media dilakukan di SMA Negeri 20 Surabaya pada 33 peserta didik kelas XI MIPA 2 yang sebelumnya telah menerima materi laju reaksi. Media pembelajaran berbasis website ini dinyatakan layak digunakan. Hasil validitas isi dan konstruk menunjukkan hasil yang valid pada setiap aspek dengan modus antara 4 dan 5. Hasil kepraktisan menunjukkan bahwa media pembelajaran berbasis website praktis dengan 98,10% aktivitas peserta didik yang relevan pada pertemuan pertama dan 99,05% pada pertemuan kedua, sedangkan perolehan persentase tiap aspek pada respon peserta didik mendapatkan persentase  90%. Hasil keefektifan media pembelajaran diperoleh hasil ketuntasan klasikal sebesar 87,9% dan nilai N-Gain sebesar 0,78. Hal ini didukung dengan hasil uji Paired sample t-test sebesar 0,000 yang berarti terdapat perbedaan rata-rata hasil belajar yang signifikan.

This development research aims to describe the feasibility of website-based learning media for reaction-rate material. The feasibility of learning media is reviewed in terms of validity, practicality, and effectiveness. Media validity is measured by content validity and construct validity. The practicality of the media is measured by student responses and activities. Effectiveness is measured by the percentage of classical completeness and the improvement of students' learning outcomes. The research method used in this research is Borg and Gall's Research and Development (R&D) method, which has been modified by Sukmadinata. Media trials were conducted at SMA Negeri 20 Surabaya on 33 students of class XI MIPA 2 who had previously received reaction rate material. This website-based learning medium is declared feasible. The results of content and construct validity show valid results in each aspect with a mode between 4 and 5. Practicality results show that web-based learning media is practical with 98,10% of relevant student activities at the first meeting and 99,05% at the second meeting, while the percentage acquisition of each aspect in the student response gets a percentage of  90%. The results of the effectiveness of learning media obtained classical completeness results of 87.9% and an N-Gain score of 0.78. This is supported by the results of the Paired sample t-test of 0.000, which means there is a significant average difference in learning outcomes.
