Abstract

ABSTRAK Penelitian ini dilatarbelakangi oleh rendahnya keaktifan belajar peserta didik pada mata pelajaran Ilmu Pengetahuan Alam dan Sosial (IPAS) di kelas V MIN 12 Bandar Lampung, yang terlihat dari kurangnya partisipasi dalam diskusi, ketidakteraturan mencatat materi, serta rendahnya keberanian dalam bertanya maupun menjawab pertanyaan guru. Berdasarkan latar belakang, identifikasi, dan pembatasan masalah tersebut, tujuan dari penelitian ini adalah untuk menjawab rumusan masalah: “Apakah penerapan model Problem Based Learning (PBL) dapat meningkatkan keaktifan siswa pada mata pelajaran IPAS kelas V MIN 12 Bandar Lampung?” Penelitian ini menggunakan metode Penelitian Tindakan Kelas (PTK) dengan dua siklus. Teknik pengumpulan data dilakukan melalui observasi dengan menggunakan lembar observasi keaktifan belajar, dan data dianalisis secara deskriptif. Hasil penelitian menunjukkan bahwa penerapan model PBL memberikan dampak positif terhadap peningkatan keaktifan belajar siswa. Pada siklus I, sebanyak 52% siswa berada pada kategori "mulai berkembang" dan 33% berada pada kategori "berkembang sesuai harapan". Setelah dilakukan perbaikan pembelajaran pada siklus II, keaktifan belajar meningkat secara signifikan, dengan 76% siswa mencapai kategori "berkembang sangat baik". Hampir semua indikator keaktifan mengalami peningkatan, terutama dalam partisipasi diskusi, keberanian bertanya, membaca, dan kedisiplinan mengumpulkan tugas. Dengan demikian, penerapan model Problem Based Learning terbukti efektif dalam meningkatkan keaktifan belajar dan menciptakan suasana pembelajaran yang lebih interaktif serta berpusat pada peserta didik.

Based on the background, problem identification, and problem limitation, this study aims to answer the research question: “Can the implementation of the Problem Based Learning (PBL) model improve student activeness in the IPAS subject for Grade V at MIN 12 Bandar Lampung?” This research employed a Classroom Action Research (CAR) method with two cycles. Data were collected through observation using a learning activeness observation sheet and analyzed descriptively. The results show that the application of the PBL model had a positive impact on improving students’ learning activeness. In the first cycle, 52% of students were in the "starting to develop" category, and 33% had reached the "developing as expected" category. After improvements in the second cycle, student activeness increased significantly, with 76% reaching the "developing very well" category. Almost all indicators of activeness showed improvement, especially in discussion participation, asking questions, reading, and discipline in submitting assignments. Therefore, the implementation of the Problem Based Learning model is proven to be effective in increasing student activeness and creating a more interactive and student-centered learning environment.
