Abstract

Abstrak Batik Seluang Mudik merupakan salah satu kain batik khas Kabupaten Sarolangun, Provinsi Jambi, yang menampilkan motif utama berupa ikan seluang (Rasbora sp.) yang bermigrasi melawan arus sungai. Motif ini terinspirasi dari fenomena alam sungai-sungai di Sarolangun, khususnya perilaku musiman ikan seluang yang berenang ke hulu untuk bertelur. Penelitian ini bertujuan mengeksplorasi konsep-konsep matematika yang termuat dalam motif Batik Seluang Mudik Sarolangun Jambi. Pendekatan yang digunakan adalah kualitatif dengan metode etnografi. Hasil kajian menunjukkan bahwa motif batik tersebut memuat berbagai konsep matematika, antara lain: (1) geometri transformasi yang meliputi translasi, refleksi, rotasi, dan dilatasi; (2) konsep simetri dan pola berulang; (3) karakteristik fraktal dalam pengulangan motif; (4) geometri bidang seperti segitiga, elips, dan kurva lengkung; serta (5) konsep proporsi dan perbandingan dalam komposisi warna. Temuan ini mengindikasikan bahwa Batik Seluang Mudik berpotensi besar sebagai media pembelajaran matematika yang kontekstual dan berbasis kearifan lokal.   Kata kunci: Etnomatematika, Batik Seluang Mudik, Sarolangun, Geometri Transformasi, Budaya Lokal Abstract Seluang Mudik Batik is one of the traditional batik fabrics originating from Sarolangun Regency, Jambi Province, Indonesia. Its main motif depicts the seluang fish (Rasbora sp.) migrating upstream against the river current. This motif is inspired by a natural phenomenon commonly observed in the rivers of Sarolangun, particularly the seasonal behavior of seluang fish swimming upstream to spawn.This study aims to explore the mathematical concepts embedded in the motifs of Seluang Mudik Batik from Sarolangun, Jambi. The research employed a qualitative approach using an ethnographic method. The findings reveal that the batik motif contains various mathematical concepts, including: (1) geometric transformations such as translation, reflection, rotation, and dilation; (2) symmetry and repeating patterns; (3) fractal characteristics reflected in the recurring motifs; (4) plane geometry concepts, including triangles, ellipses, and curved forms; and (5) proportional and comparative relationships in color composition.These findings indicate that Seluang Mudik Batik has significant potential as a contextual mathematics learning resource rooted in local cultural wisdom, enabling students to connect mathematical concepts with their cultural environment.

Abstract

Abstrak Penelitian ini bertujuan untuk menganalisis kemampuan pemecahan masalah matematis siswa kelas VIII MTs N 2 Sarolangun pada materi pecahan serta mengidentifikasi kesulitan yang dialami siswa dalam setiap tahapan pemecahan masalah. Penelitian ini menggunakan pendekatan deskriptif kualitatif dengan subjek penelitian siswa kelas VIII yang dipilih berdasarkan kategori kemampuan tinggi, sedang, dan rendah. Teknik pengumpulan data dilakukan melalui tes uraian dan wawancara. Analisis data meliputi reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa siswa dengan kemampuan tinggi mampu memahami masalah, menyusun strategi, melaksanakan perhitungan, dan memeriksa kembali jawaban dengan baik. Siswa dengan kemampuan sedang dapat memahami masalah dan menentukan strategi, tetapi masih kurang teliti dalam perhitungan serta jarang memeriksa kembali hasil akhir. Sementara itu, siswa dengan kemampuan rendah mengalami kesulitan dalam memahami soal, menentukan langkah penyelesaian, dan melakukan operasi hitung pecahan. Kesalahan yang ditemukan meliputi kesalahan konsep, prosedural, dan ketelitian. Berdasarkan hasil penelitian, dapat disimpulkan bahwa kemampuan pemecahan masalah matematis siswa masih bervariasi sehingga diperlukan pembelajaran yang membiasakan siswa mengikuti tahapan pemecahan masalah secara sistematis. Kata kunci: Pemecahan Masalah Matematis, Pecahan, siswa kelas VIII, penelitian kualitatif. Abstract This study aimed to analyze the mathematical problem-solving abilities of eighth-grade students at MTs N 2 Sarolangun on fraction material and to identify the difficulties experienced by students at each stage of problem solving. The study employed a qualitative descriptive approach involving students categorized into high, medium, and low ability levels. Data were collected through essay tests and interviews. The data analysis techniques included data reduction, data presentation, and conclusion drawing. The results showed that students with high ability were able to understand problems, develop appropriate strategies, perform calculations correctly, and recheck their answers systematically. Students with medium ability generally understood the problems and determined suitable strategies but were less accurate in calculations and rarely reviewed their final answers. Meanwhile, students with low ability experienced difficulties in understanding problems, determining solution steps, and performing fraction operations correctly. The common errors found included conceptual, procedural, and calculation accuracy errors. In conclusion, students’ mathematical problem-solving abilities varied significantly; therefore, learning activities that train students to follow systematic problem-solving stages are needed to improve their abilities. Keywords: Mathematical Problem-solving, fractions, eighth-grade students, qualitative research.
