Abstract

Penelitian ini dilatarbelakangi oleh rendahnya hasil belajar matematika di SMP Negeri 4 Muara Bungo. Tujuan penelitian ini adalah untuk mengetahui apakah hasil belajar matematika peserta didik setelah menerapkan model Project Based Learning (PjBL) lebih baik dibandingkan sebelum menerapkan model Project Based Learning (PjBL) pada peserta didik kelas IX SMP Negeri 4 Bungo. Jenis penelitian ini adalah Pre-eksperimen dengan desain the one-group pretest-posttest design. Populasi penelitian ini adalah seluruh peserta didik kelas IX SMP Negeri 4 Muara Bungo pada semester ganjil tahun ajaran 2025/2026. Subjek penelitian dipilih melalui teknik purposive sampling, sehingga terpilih kelas IX.1 yang berjumlah 32 peserta didik sebagai sampel. Instrumen yang digunakan dalam penelitian berupa tes pretest-posttest berbentuk esai yang memuat indikator hasil belajar peserta didik dengan reliabilitas 0,69. Teknik analisis data pengujian hipotesis menggunakan uji-t. Hasil uji hipotesis diperoleh nilai  sebesar 18,41 dan  2,03 pada taraf nyata α = 0,05 sehingga hipotesis diterima. Rata-rata hasil belajar peserta didik mengalami peningkatan mengalami peningkatan dari 19,37 menjadi 61,28. Maka dapat disimpulkan bahwa hasil belajar matematika peserta didik setelah menerapkan model Project Based Learning (PjBL) lebih baik dibandingkan sebelum menerapkan model Project Based Learning (PjBL) pada peserta didik kelas IX SMP Negeri 4 Muara Bungo.

Abstract

Mathematics is often perceived as an abstract, universal, and culture-free discipline, presented in formal symbols and rigid procedures that appear distant from learners’ everyday realities. This research investigated fractal concepts in ethnomathematics in relation to the Minangkabau songket textile. This research employed a qualitative case study design. Data were collected using a document checklist of the songket and a semi-structured interview. Data were analyzed using document analysis and thematic analysis. The research population was the Minangkabau songket textile, and the sampling method was purposive; three songket motifs from Pandai Sikek, West Sumatra, were selected. The results reveal repeated patterns of self-similarity, iteration, recursion, symmetry, and statistical variation, which are similar to the structures seen in nature. These patterns are not the result of formal mathematical calculation but arise from indigenous knowledge grounded in the Minangkabau philosophy alam takambang jadi guru, where nature serves as the primary source of learning. Beyond their aesthetic function, the fractal properties of songket motifs serve as visual metaphors for cultural continuity, social harmony, and the intergenerational transmission of values. This research is limited to songket produced by Pandai Sikek in West Sumatra. This study reinforces the notion that traditional cultural products are not only artistic expressions but also repositories of sophisticated mathematical knowledge.
