Abstract

ABSTRAK Penelitian ini bertujuan untuk mengembangkan Lembar Kerja Peserta Didik (LKPD) berbasis Problem Based Learning (PBL) pada mata pelajaran Ilmu Pengetahuan Alam dan Sosial (IPAS) kelas V SD. Pengembangan LKPD ini diharapkan dapat menghasilkan bahan ajar yang valid, praktis, dan layak digunakan sebagai pendukung proses pembelajaran IPAS di sekolah dasar. Lokasi penelitian ini berada di wilayah Kabupaten Lampung Selatan yang dikenal dengan kekayaan dan keragaman ekosistemnya. Penelitian ini dilatar belakangi oleh permasalahan dalam pembelajaran IPAS, yaitu keterbatasan bahan ajar yang sesuai dengan karakteristik peserta didik dan tuntutan kurikulum. LKPD yang digunakan di sekolah masih bersifat konvensional, kurang menekankan pembelajaran berbasis masalah, serta belum sepenuhnya mengaitkan materi dengan situasi nyata. Kondisi tersebut menyebabkan pembelajaran IPAS belum berjalan secara optimal, sehingga diperlukan pengembangan LKPD berbasis Problem Based Learning sebagai alternatif bahan ajar. Metode penelitian yang digunakan adalah Research and Development (R&D) dengan model ADDIE, yang terdiri dari lima tahap utama. Pada tahap analisis, dilakukan identifikasi kebutuhan, karakteristik peserta didik, analisis kurikulum, serta permasalahan pembelajaran yang terjadi di kelas. Tahap desain meliputi penyusunan rancangan LKPD berbasis Problem Based Learning, perumusan alur sintaks Problem Based Learning, serta penentuan indikator dan tujuan pembelajaran. Tahap pengembangan menghasilkan prototipe LKPD yang divalidasi oleh ahli materi dan ahli media untuk menilai kelayakan isi, tampilan, dan kesesuaian model pembelajaran. Selanjutnya, pada tahap implementasi, LKPD diuji cobakan melalui uji coba skala kecil dan skala besar untuk melihat kepraktisan dan respon peserta didik. Tahap terakhir, evaluasi, dilakukan untuk meninjau kembali kualitas produk berdasarkan masukan validator dan hasil uji coba sehingga diperoleh LKPD yang optimal dan siap digunakan dalam pembelajaran. Hasil penelitian dan pengembangan menunjukkan bahwa LKPD berbasis Problem Based Learning yang dikembangkan berada pada kategori sangat valid berdasarkan penilaian ahli. Selain itu, uji coba skala kecil menghasilkan persentase kepraktisan 87,4%, sedangkan uji coba skala besar mencapai 91,6%, keduanya termasuk kategori sangat praktis. Dengan demikian, LKPD berbasis Problem Based Learning pada mata pelajaran IPAS kelas V SD dinyatakan valid, praktis, dan layak digunakan sebagai bahan ajar pendukung pembelajaran.

The development of this LKPD is expected to produce instructional materials that are valid, practical, and feasible to be used as supporting learning resources in IPAS instruction at the elementary school level. The research was conducted in South Lampung Regency, an area known for its rich and diverse ecosystems. This study is motivated by problems encountered in IPAS learning, particularly the limited availability of instructional materials that align with students’ characteristics and curriculum demands. The LKPD used in schools is still conventional in nature, lacks emphasis on problem-based learning, and has not fully connected learning materials with real-life situations. These conditions result in IPAS learning not being implemented optimally; therefore, the development of a PBL-based LKPD is needed as an alternative instructional material. The research method employed was Research and Development (R&D) using the ADDIE model, which consists of five main stages. The analysis stage involved identifying learning needs, student characteristics, curriculum analysis, and classroom learning problems. The design stage included developing the PBL-based LKPD framework, formulating the syntax of Problem Based Learning, and determining learning indicators and objectives. The development stage produced an LKPD prototype that was validated by subject-matter experts and media experts to assess content feasibility, visual appearance, and alignment with the learning model. Furthermore, during the implementation stage, the LKPD was tested through small-scale and large-scale trials to examine its practicality and students’ responses. The final stage, evaluation, was conducted to review the product quality based on validator feedback and trial results, resulting in an optimal LKPD ready for classroom use. The results of the research and development indicate that the developed PBL-based LKPD falls into the very valid category based on expert assessments. In addition, the small-scale trial yielded a practicality percentage of 87.4%, while the large-scale trial reached 91.6%, both of which are classified as very practical. Therefore, the PBL-based LKPD for fifth-grade IPAS learning is declared valid, practical, and feasible to be used as a supporting instructional material.
