Abstract

This study aims to describe the implementation of the PHIBAR (Papan Hitung Bilangan Ratusan) media in improving students' ability to perform addition of three-digit numbers and to analyze the improvement in their skills after using this media. The research was conducted in the fourth grade of SDN Dukuh Kupang 1 Surabaya, involving 28 students as research subjects. The method used was Classroom Action Research (CAR) based on the Kemmis and McTaggart model, carried out in two cycles, with each cycle consisting of one meeting. Data were collected through observation, interviews, and tests. The results indicated that the use of PHIBAR media significantly improved students' ability to perform addition of three-digit numbers. The percentage of students achieving mastery increased from 39.29% in the pre-cycle to 64.29% in the first cycle and reached 89.29% in the second cycle. Additionally, the class average score improved from 68.21 to 86.43. The PHIBAR media proved to be effective in visualizing abstract concepts into concrete representations, helping students understand place value and carrying processes in accordance with their cognitive development stages.

Abstract

Penelitian ini bertujuan untuk mengembangkan bahan ajar digital berbasis Book Creator untuk meningkatkan hasil belajar siswa pada mata pelajaran Ilmu Pengetahuan Alam Sosial (IPAS), khususnya materi harmoni dalam ekosistem. Menggunakan pendekatan Research and Development (R&D) dengan model Borg & Gall, penelitian ini melibatkan observasi, wawancara, angket, dan tes hasil belajar. Hasil penelitian menunjukkan bahwa penggunaan bahan ajar digital ini berhasil meningkatkan rata-rata nilai siswa dari 70 pada pretest menjadi 85 pada posttest, mencerminkan peningkatan sebesar 21,4%. Umpan balik positif dari siswa dan guru menunjukkan bahwa bahan ajar ini tidak hanya meningkatkan pemahaman konsep tetapi juga membuat proses pembelajaran lebih menarik dan menyenangkan. Temuan ini mengindikasikan bahwa integrasi teknologi dalam pendidikan dapat secara signifikan mempengaruhi hasil belajar siswa dan mendukung kebijakan pendidikan yang mendorong penggunaan media pembelajaran interaktif di sekolah dasar.
