Abstract

Penelitian ini bertujuan untuk mendeskripsikan proses dan membuktikan peningkatan konsentrasi belajar siswa kelas III B SDN Guntur 01 pada pembelajaran IPA melalui penerapan model Problem Based Learning. Hal ini didasarkan pada hasil observasi awal yang menunjukkan bahwa 15 dari 22 siswa hanya mampu mempertahankan fokus selama 5–10 menit dan hanya 31,82% siswa yang mencapai kriteria konsentrasi belajar yang diharapkan. Penelitian ini menggunakan metode Penelitian Tindakan Kelas (PTK) dengan desain Kemmis dan McTaggart yang dilaksanakan dalam dua siklus, masing-masing terdiri dari tiga pertemuan. Subjek penelitian adalah 22 siswa kelas III B SDN Guntur 01. Pengumpulan data dilakukan melalui lembar observasi konsentrasi belajar, kuesioner konsentrasi belajar, lembar observasi aktivitas guru dan siswa, serta dokumentasi. Kriteria keberhasilan ditetapkan apabila minimal 80% siswa memperoleh skor ≥ 69 pada observasi dan skor ≥ 77 pada kuesioner konsentrasi belajar. Hasil penelitian menunjukkan bahwa konsentrasi belajar siswa meningkat dari 31,82% pada pra siklus menjadi 59,09% pada Siklus I dan 86,36% pada Siklus II berdasarkan data observasi. Hasil kuesioner juga meningkat dari 68,18% pada Siklus I menjadi 81,82% pada Siklus II. Aktivitas guru meningkat dari 79,17% menjadi 95,83% dan aktivitas siswa meningkat dari 75% menjadi 93,33%. Dengan demikian, penerapan model Problem Based Learning terbukti efektif meningkatkan konsentrasi belajar IPA siswa kelas III B SDN Guntur 01 dan penelitian dinyatakan berhasil pada Siklus II. ***** This study aims to describe the process and prove the improvement of learning concentration of class III B students at SDN Guntur 01 in science learning through the implementation of the Problem Based Learning model. This is based on initial observation results showing that 15 out of 22 students were only able to maintain focus for 5–10 minutes and only 31.82% of students achieved the expected learning concentration criteria. This research used the Classroom Action Research (CAR) method with the Kemmis and McTaggart design, conducted in two cycles, each consisting of three meetings. The research subjects were 22 students of class III B at SDN Guntur 01. Data collection was carried out through learning concentration observation sheets, learning concentration questionnaires, teacher and student activity observation sheets, and documentation. The success criteria were set at a minimum of 80% of students obtaining a score ≥ 69 on the observation and a score ≥ 77 on the learning concentration questionnaire. The results showed that students' learning concentration increased from 31.82% in the pre-research stage to 59.09% in Cycle I and 86.36% in Cycle II based on observation data. Questionnaire results also increased from 68.18% in Cycle I to 81.82% in Cycle II. Teacher activity increased from 79.17% to 95.83% and student activity increased from 75% to 93.33%. Therefore, the implementation of the Problem Based Learning model was proven to be effective in improving the science learning concentration of class III B students at SDN Guntur 01, and the research was declared successful in Cycle II.
