Abstract

Motif anyaman pada dinding anjung Rumah Bubungan Tinggi menampilkan pola berulang yang dapat dimodelkan sebagai barisan biner. Penelitian eksploratif kualitatif ini merepresentasikan orientasi bilah sebagai digit 1 dan 0, kemudian menganalisis periodisitas, memformulasikan aturan berbasis modulo, serta melakukan konversi biner–desimal–karakter untuk menautkan motif tradisional dengan struktur pengodean informasi digital. Hasil menunjukkan motif membentuk barisan biner deterministik berperiode tertentu yang dapat dijelaskan melalui fungsi modulo. Berdasarkan pemetaan digit–arah bilah, disusun pula model konseptual steganografi: penyisipan pesan biner melalui variasi orientasi bilah tanpa mengubah karakter visual motif. Temuan ini menegaskan potensi motif anyaman sebagai media representasi informasi sekaligus konteks budaya untuk pembelajaran matematika diskret melalui tugas bertahap (pengodean motif, identifikasi unit ulang/periode, penurunan aturan modulo, dan konversi bilangan). Motif weaving on the anjung wall of the Rumah Bubungan Tinggi exhibits repeating patterns that can be modeled as binary sequences. This qualitative exploratory study encodes strip orientation as 1 and 0, then examines periodicity, formulates modulo-based rules, and performs binary–decimal–character conversions to connect traditional motifs with the basic structure of digital information encoding. The results show that the motifs form deterministic binary sequences with specific periods that can be described using modulo functions. Based on digit-to-orientation mapping, the study also proposes a conceptual motif-based steganography model: embedding binary messages through variations in strip orientation without altering the motif’s overall visual character. These findings highlight the potential of weaving motifs as both an information representation medium and a cultural context for discrete mathematics learning through stepwise tasks (motif encoding, identification of repeating units/periods, derivation of modulo rules, and number conversion).

Abstract

Abstract:  21st-century mathematics education demands the application of approaches that can develop conceptual understanding, critical thinking skills, creativity, and student collaboration. One of the relevant approaches is deep learning, but its implementation in schools still faces various challenges, especially the limited understanding of teachers in selecting learning models and developing appropriate teaching materials. This community service activity aims to facilitate MTs Tabalong teachers and teachers involved in the Mathematics MGMP throughout the city of Banjarmasin in designing and implementing Project-Based Learning (PjBL) based learning tools with a deep learning approach. The activity was conducted using a participatory training approach thru four stages: problem identification, preparation, implementation, and evaluation, with a hybrid implementation model. The participants of the activity numbered 80 teachers, consisting of 30 teachers from MTs Tabalong and 50 teachers from SMA/MA or equivalent. Data were obtained thru teacher response questionnaires and the review of teaching materials. The results show a very positive response, the material is considered relevant and beneficial, and it enhances teachers' understanding and readiness. Although the number of devices produced is not yet optimal, their quality has reflected the main characteristics of PjBL and deep learning. These findings indicate that the workshop is effective as an initial step in enhancing pedagogical competence and needs to be followed up with continuous mentoring.Abstrak: Implementasi pendekatan deep learning dalam pembelajaran matematika di sekolah masih menghadapi kendala, terutama keterbatasan guru dalam merancang perangkat pembelajaran yang sesuai. Kegiatan pengabdian kepada masyarakat ini bertujuan memfasilitasi guru MTs Tabalong dan guru yang tergabung dalam MGMP Matematika se-Kota Banjarmasin dalam merancang dan mengimplementasikan perangkat pembelajaran berbasis Project-Based Learning (PjBL) dengan pendekatan deep learning. Kegiatan dilaksanakan menggunakan pendekatan pelatihan partisipatif melalui empat tahapan, yaitu identifikasi masalah, persiapan, pelaksanaan, dan evaluasi, dengan model pelaksanaan hybrid. Peserta kegiatan berjumlah 80 guru, terdiri atas 30 guru MTs Tabalong dan 50 guru SMA/MA sederajat. Data diperoleh melalui angket respon guru dan telaah perangkat pembelajaran. Hasil menunjukkan respon sangat positif, materi dinilai relevan dan bermanfaat, serta meningkatkan pemahaman dan kesiapan guru. Meskipun jumlah perangkat yang dihasilkan belum optimal, kualitasnya telah mencerminkan karakteristik utama PjBL dan deep learning. Temuan ini menunjukkan bahwa workshop efektif sebagai langkah awal peningkatan kompetensi pedagogik dan perlu ditindaklanjuti dengan pendampingan berkelanjutan.

Abstract

Pembelajaran matematika pada materi kubus dan balok masih sering menghadapi kendala karena peserta didik cenderung menghafal rumus tanpa memahami konsep bangun ruang secara konkret. Penelitian ini bertujuan untuk mengetahui efektivitas model Project-Based Learning terhadap hasil belajar matematika peserta didik kelas V MI Negeri 11 Hulu Sungai Selatan pada materi kubus dan balok. Keunggulan penelitian ini terletak pada penerapan proyek konstruksi model tiga dimensi kubus dan balok sebagai aktivitas manipulatif yang menghubungkan objek konkret dengan konsep sifat-sifat dan luas permukaan bangun ruang. Penelitian ini menggunakan pendekatan kuantitatif dengan metode eksperimen semu dan desain pretest-posttest control group design. Sampel penelitian terdiri atas 56 peserta didik, yaitu 29 peserta didik kelas eksperimen dan 27 peserta didik kelas kontrol. Data dikumpulkan melalui tes hasil belajar dan dianalisis menggunakan uji normalitas, uji homogenitas, dan Independent Samples T-Test. Hasil penelitian menunjukkan bahwa rata-rata nilai posttest kelas eksperimen sebesar 85,86, sedangkan kelas kontrol sebesar 65,00. Hasil uji Independent Samples T-Test menunjukkan nilai signifikansi kurang dari 0,001. Temuan ini menegaskan bahwa Project-Based Learning efektif meningkatkan hasil belajar matematika pada materi kubus dan balok, terutama karena pembelajaran memberi pengalaman konkret bagi peserta didik dalam memahami konsep bangun ruang.

Abstract

This study explores ethnomathematical elements embedded in the architecture of four historic mosques in Banjarmasin City—Jami Sungai Jingah Mosque, Nurul Amilin Mosque, Sultan Suriansyah Mosque, and Tughfaturraghibin Mosque—and examines their potential contributions to secondary mathematics learning. A qualitative exploratory approach was employed, with data collected through visual observation, photographic documentation, and semi-structured interviews. Data were analyzed iteratively through data reduction, data display, and conclusion drawing. The findings show that key architectural features—such as column arrangements, roof forms, ornaments, and spatial organization—embody explicit mathematical ideas, including pattern regularity, plane and solid geometry, similarity, symmetry, and geometric transformations. Extending mosque-based ethnomathematics research beyond single-site descriptions, this cross-case exploration of historic mosques highlights recurring and distinctive geometric structures that can be leveraged for contextual learning. The study contributes a curriculum-oriented mapping of the identified elements to junior and senior secondary geometry topics, providing a basis for designing culturally grounded tasks and teaching materials.
