Abstract

Berawal dari ketidakpahaman peserta didik tentang menentukan persentase untung atau rugi. Peserta didik mengalami kesulitan dalam menghubungkan konsep persentase dengan situasi nyata, sehingga pembelajaran menjadi kurang bermakna. Penelitian ini bertujuan untuk menghasilkan lintasan belajar menggunakan pendekatan PMRI dengan konteks menjual new math pempek untuk membantu peserta didik memahami konsep persentase untung dan rugi secara lebih mendalam. Penelitian ini melibatkan 25 siswa di MTs Darul Ulum dan menggunakan metode penelitian desain: preliminary design, experimental design, dan retrospective analysis. Data dianalisis secara retrospektif melalui jawaban lembar kerja siswa, video, dokumentasi berupa foto, dan wawancara. Hasil dari penelitian ini adalah lintasan belajar yang terdiri dari tiga kegiatan: (1) memperkirakan dan menghitung persentase keuntungan, (2) memperkirakan dan menghitung persentase kerugian, dan (3) menyelesaikan masalah persentase keuntungan dan kerugian yang lebih rumit. Dengan menggunakan pendekatan kontekstual, siswa lebih tertarik dan percaya diri dalam memahami materi, sehingga pembelajaran menjadi lebih bermakna. It all started with students' lack of understanding of determining profit or loss percentages. Students had difficulty connecting the concept of percentages to real-life situations, making learning less meaningful. This study aimed to create a learning trajectory using the PMRI approach in the context of selling New Math Pempek to help students understand the concept of profit and loss percentages more deeply. This study involved 25 students at MTs Darul Ulum and employed design research methods, including preliminary design, experimental design, and retrospective analysis. Data were analyzed retrospectively through student worksheet answers, videos, photo documentation, and interviews. The results of this study were a learning trajectory consisting of three activities: (1) estimating and calculating profit percentages, (2) estimating and calculating loss percentages, and (3) solving more complex profit and loss percentage problems. By adopting a contextual approach, students became more engaged and confident in understanding the material, thereby making learning more meaningful.

Abstract

This study has the urgency to examine how the implementation of the Pancasila Student Profile Strengthening Project (P5) at SDN Madugondo serves as a strategic effort to shape students’ character in line with the direction of the Merdeka Curriculum policy. The research employed a descriptive method with a qualitative approach through observation, semi-structured in-depth interviews, and documentation techniques. The researcher acted as the key instrument in observation, while informants were purposively selected, consisting of the Principal, Homeroom Teachers, Project Coordinator Teacher, and four students from grades 1, 3, and 4. Data analysis was conducted using Miles and Huberman’s model, which includes data reduction, data display, and conclusion drawing, while data validity was ensured through source and technique triangulation. The findings reveal that during the planning stage, teachers prepared project dimensions and themes relevant to sustainable lifestyles; in the implementation stage, coordination was carried out with the principal and other teachers, dissemination was provided to parents and students, and evaluation instruments were developed; whereas in the evaluation stage, teachers observed the learning process, used assessment rubrics, and evaluated the achievement of the Pancasila Student Profile dimensions. The practical implementation of this study demonstrates that P5 is not merely a formal program, but can also be sustainably integrated into the school culture through collaboration among teachers, parents, and students. Scientifically, the results of this study enrich the discourse on implementation strategies of the Merdeka Curriculum, particularly at the elementary school level.

Abstract

The current cultural context has become a significant focus in mathematics education, serving not only as a bridge to formal understanding but also as a means of cultural preservation. This study aims to analyse the use of Palembang's cultural context in mathematics education through the Indonesian Realistic Mathematics Education (PMRI) approach. The analysis was conducted on articles indexed in Scopus and Google Scholar based on publication year, content, methods, student skills developed, and research findings. Data analysis techniques were based on the PIECES framework (Planning, Identifying, Evaluating, Collecting/Elaborating, Explaining, and Summarising). From the selection process, 20 articles that met the inclusion criteria were obtained. The analysis results showed that the dominant cultural context of Palembang included traditional food (pempek), traditional fabrics (songket and jumputan), and trading activities on the Musi River. The most frequently studied mathematical topics were geometry and algebra, with the design research method used as an approach to design learning and develop media such as worksheets, educational videos, and evaluation instruments. The students' ability most frequently focused on was conceptual understanding. These findings provide significant contributions to educators and researchers in developing context-based cultural mathematics learning through the PMRI approach.

Abstract

Pembelajaran IPA sering dianggap sulit dipahami oleh peserta didik sehingga diperlukan pendekatan pembelajaran yang dapat meningkatkan pemahaman konsep dalam pembelajaran IPA. Penelitian ini bertujuan untuk mengidentifikasi perbedaan signifikan dalam penerapan model Pembelajaran Berbasis Masalah (Problem Based Learning) dengan dukungan media konkret terhadap pemahaman konsep IPA (Ilmu Pengetahuan Alam) pada siswa kelas lima di SDN 01 Sidowaluyo. Rumusan masalah penelitian ini adalah untuk mengidentifikasi apakah terdapat perbedaan dalam penerapan model Pembelajaran Berbasis Masalah dengan media konkret terhadap pemahaman konsep IPA pada siswa kelas lima. Penelitian ini menggunakan desain Nonrandomized pretest-posttest control group. Tahap awal melibatkan pemberian pretest kepada siswa, diikuti dengan pemberian perlakuan menggunakan model Pembelajaran Berbasis Masalah yang didukung oleh media konkret, dan tahap terakhir adalah pelaksanaan posttest. Hasil penelitian menunjukkan bahwa penerapan model Pembelajaran Berbasis Masalah yang didukung oleh media konkret secara signifikan meningkatkan pemahaman siswa terhadap konsep IPA. Analisis data menunjukkan nilai signifikansi lebih rendah dari α (0,05), sehingga hipotesis nol ditolak dan hipotesis alternatif diterima. Rata-rata skor pretest pada kelompok kontrol adalah 44,00, dan skor posttest adalah 82,35, sedangkan kelompok eksperimen memperoleh skor pretest 46,25 dan skor posttest 91,6. Peningkatan ini dapat dikaitkan dengan penerapan model PBL yang didukung oleh media konkret, yang disesuaikan dengan kebutuhan siswa dan memanfaatkan media konkret untuk membantu mereka dalam memahami konsep yang diajarkan, terutama dalam topik sifat-sifat cahaya.
