Zahra Zakiah Lubis (2026). Efektivitas Pembelajaran Model Problem Based Learning terhadap Materi Lingkaran Berbantuan Website Desmos. [Skripsi. Universitas Syiah Kuala]. Di bawah bimbingan Prof. Dr. Mailizar, S.Pd., M.Ed., dan Dra. Tuti Zubaidah, M.Pd. Pembelajaran matematika pada materi lingkaran masih menghadapi berbagai kendala karena pembelajaran yang diterapkan cenderung berpusat pada guru sehingga keterlibatan siswa dalam proses pembelajaran belum optimal. Salah satu upaya untuk mengatasi permasalahan tersebut adalah dengan menerapkan model pembelajaran Problem Based Learning (PBL) berbantuan website Desmos. Penelitian ini bertujuan untuk mengetahui efektivitas penerapan model PBL berbantuan website Desmos pada materi lingkaran. Penelitian ini menggunakan pendekatan kuantitatif deskriptif. Subjek penelitian ini adalah 31 siswa kelas VIII1 SMP Negeri 8 Banda Aceh. Data dikumpulkan menggunakan lembar observasi kemampuan guru, lembar observasi aktivitas siswa, angket respons siswa, dan tes hasil belajar pada materi lingkaran. Data dianalisis menggunakan nilai rata-rata dan persentase. Hasil penelitian menunjukkan bahwa rata-rata kemampuan guru dalam mengelola pembelajaran sebesar 3,78, persentase aktivitas siswa sebesar 91%, persentase respons siswa sebesar 72%, dan ketuntasan hasil belajar siswa secara klasikal sebesar 97%. Berdasarkan hasil tersebut, model pembelajaran Problem Based Learning (PBL) berbantuan website Desmos efektif diterapkan pada materi lingkaran di SMP Negeri 8 Banda Aceh. Kata kunci: Efektivitas Pembelajaran, Problem Based Learning, Website Desmos, Lingkaran.

Zahra Zakiah Lubis (2026). The Effectiveness of Problem-Based Learning Model on Circle Material Assisted by the Desmos Website. [Skripsi. Syiah Kuala University]. Under the guidance of Prof. Dr. Mailizar, S.Pd., M.Ed., and Dra. Tuti Zubaidah, M.Pd. Mathematics learning on the topic of circles still faces various obstacles because the learning applied tends to be teacher-centered so that student involvement in the learning process is not optimal. One effort to overcome this problem is by implementing the Problem Based Learning (PBL) learning model assisted by the Desmos website. This study aims to determine the effectiveness of the application of the PBL model assisted by the Desmos website on the topic of circles. This study uses a descriptive quantitative. The subjects of this study were 31 students of class VIII-1 SMP Negeri 8 Banda Aceh. Data were collected using teacher ability observation sheets, student activity observation sheets, student response questionnaires, and learning outcome tests on the topic of circles. Data were analyzed using average values and percentages. The results showed that the average teacher ability in managing learning was 3.78, the percentage of student activity was 91%, the percentage of student responses was 72%, and the completeness of student learning outcomes in a classical manner was 97%. Based on these results, the Problem Based Learning (PBL) learning model assisted by the Desmos website is effectively applied to the topic of circles at SMP Negeri 8 Banda Aceh.
