Hingga saat ini, belum ditemukan studi yang secara eksplisit mengeksplorasi keterkaitan antara arsitektur Rumah Bari Pesirah dan konsep matematika dalam perspektif etnomatematika, padahal bangunan ini mencerminkan nilai budaya yang berpotensi memperkaya konteks pembelajaran geometri di tingkat SMP. Penelitian ini bertujuan untuk mendeskripsikan hasil eksplorasi etnomatematika berupa makna filosofis pada rancang bangun Rumah Bari Pesirah Pangkalan Balai serta mengidentifikasi konsep-konsep matematika yang terdapat pada ornamen dan arsitektur bangunan. Penelitian ini dilakukan karena Rumah Bari Pesirah merupakan salah satu contoh arsitektur tradisional di Sumatera Selatan yang memiliki nilai budaya dan sejarah yang tinggi, namun belum dieksplorasi dari sudut pandang etnomatematika. Selain itu, penelitian ini juga dilatarbelakangi oleh pentingnya mengintegrasikan budaya lokal dalam pembelajaran matematika agar pembelajaran menjadi lebih bermakna dan relevan bagi peserta didik. Penelitian ini menggunakan pendekatan etnografi dengan teknik wawancara terhadap tokoh adat dan pengrajin lokal, observasi langsung terhadap struktur bangunan, serta dokumentasi arsitektural yang dianalisis menggunakan pendekatan tematik. Hasil penelitian menunjukkan bahwa pola ukiran berbentuk segi empat simetris pada dinding mencerminkan konsep geometri bidang datar, sedangkan struktur atap berbentuk limas memperlihatkan pemahaman terhadap volumetrik bangun ruang. Konsep-konsep ini selaras dengan capaian pembelajaran geometri dan pengukuran di SMP. Kedua elemen konten itu sesuai atau dapat digunakan dalam pembelajaran matematika di tingkat SMP. Penelitian ini diharapkan dapat memberikan kontribusi dalam pengembangan pembelajaran matematika yang bermakna melalui integrasi budaya lokal.

Kemampuan representasi matematika memegang peranan krusial dalam pemahaman konsep dan pemecahan masalah program linear. Sayangnya, beragam penelitian mengungkap beragam hasil terkait kemampuan representasi matematis siswa pada Program Linear. Systematic Literature Review (SLR) terhadap 11 artikel terbitan 2021-2025, berfokus pada siswa kelas XI, menyoroti dominasi representasi simbolik yang lebih dikuasai, sementara representasi visual dan verbal masih menjadi kendala. Faktor-faktor seperti gaya belajar, minat, dan pola pikir siswa terbukti signifikan memengaruhi kemampuan representasi ini. Lebih lanjut, model pembelajaran inovatif seperti Connected Mathematics Project (CMP) menunjukkan keunggulan dibandingkan metode konvensional. Temuan ini menggarisbawahi urgensi penerapan strategi pembelajaran yang kontekstual, interaktif, dan adaptif terhadap karakteristik siswa demi meningkatkan kemampuan matematis siswa pada materi program linear.

Purpose: This study aimed to develop and evaluate culturally contextualized student worksheets that integrate mathematical modeling with ethnomathematical elements from the Bidar Boat Festival. The goal was to enhance students’ modeling competencies and engagement. Method: The research employed a design-based research (DBR) approach, consisting of a preliminary study and a formative evaluation phase through iterative prototyping. Data collection involved expert validation, classroom observations, student interviews, and written assessments across three cycles with 24 junior high school students. Findings: The developed worksheets were found to be highly valid and practical. Students demonstrated strong performance on key modeling competencies: 97.5% understood the tasks, 93.54% translated real-life contexts into mathematical models, 81.88% applied mathematical operations accurately, and 80.42% interpreted results appropriately. Additionally, the learning tools enhanced student motivation, cultural awareness, and mathematical understanding. Significance: Embedding local cultural contexts, such as the Bidar Boat Festival, into mathematics instruction can bridge abstract mathematical concepts with students' lived experiences. The approach not only improved cognitive learning outcomes but also encouraged reflective thinking and cultural appreciation. The study contributes a replicable model for implementing culturally responsive, competency-based mathematics education.

Understanding the concept of the cube remains a challenge for elementary school students due to the lack of concrete and contextual learning materials. Abstract learning makes it difficult for students to understand the shape and nature of building spaces. This study aims to analyse the need for developing geometry learning media in the form of pop-up books based on Indonesian Realistic Mathematics Education (PMRI) using cube materials in grade 2 elementary school. The research method used is Design Research. Data collection was conducted through interviews with three mathematics teachers and twenty-four second-grade students of SDN 1 Air Balui in Musi Banyuasin Regency. The analysis of student needs employs closed interviews. In contrast, the analysis of teacher needs utilises semi-structured interviews to gather more in-depth information about the needs and expectations of geometry learning media among grade II students. Data were analysed using qualitative descriptive analysis, employing the Miles and Huberman analysis approach through three stages: data reduction, data presentation, and conclusion. The results show that teachers and students have a high need for visual, manipulative, and integrated learning media to explain the properties of cubes. The percentage analysis indicates very high scores in pedagogical (90–94%), technical (85%), aesthetic (92%), and evaluation aspects (88–90%), while cognitive aspects (77–79%) are categorised as high. These findings suggest that PMRI-based pop-up books have the potential to enhance students' Understanding of concepts by connecting abstract geometric concepts to concrete experiences. The results of this needs analysis are the basis for the development and validation stage of contextual, engaging, and practical geometry learning media for basic education.
