Abstract

This study reviews various research works on ethnomathematics within Indonesian culinary traditions using a Systematic Literature Review (SLR) approach. The main goal is to identify dominant mathematical concepts, explore embedded cultural values, and highlight potential directions for future studies. Data were collected from Google Scholar following the PRISMA framework, resulting in 15 selected articles for analysis. Findings show that geometry is the most prominent concept, followed by measurement, arithmetic, and social arithmetic. Traditional foods such as lemang, onde-onde, and tumpeng illustrate three-dimensional geometric forms and the application of measurement and proportion in cooking processes. Cultural values like togetherness, precision, balance, and the preservation of tradition are reflected through these practices. However, most studies remain descriptive without empirical classroom application. Therefore, developing teaching materials and learning models based on culinary ethnomathematics is needed to promote more meaningful and contextual mathematics learning.

Abstract

This study aims to describe the characteristics and types of errors made by eleventh-grade high school students, along with their percentages of occurrence at each stage of Newman's Error Analysis (NEA), when solving quadratic function problems. A descriptive qualitative method supported by percentage analysis of student errors was employed. The research subjects consisted of 30 eleventh-grade high school students selected using purposive sampling. Data were collected through a validated open-ended diagnostic test and analyzed using the Miles and Huberman model. The analysis results show that errors occurred at all stages of the NEA, with the following average percentage distributions: reading errors at 4.7%, comprehension errors at 66.7%, transformation errors at 63.3%, process skill errors at 73.3%, and Encoding errors at 78.0%. Reading errors had the lowest frequency, while students' main difficulties were observed at the process-skills and final-answer-writing stages, particularly in contextual problems and algebraic manipulation involving fractions. Students' errors were systematic and hierarchical, with deficiencies at the transformation and process-skills stages as the dominant factors contributing to students' failure to produce accurate final answers. The findings recommend strengthening students' conceptual understanding of the vertex, factoring of quadratic functions, and basic procedural algebra skills in classroom instruction.

Abstract

Pohon merentang minimum merupakan salah satu topik pada teroi graf yang dapat digunakan untuk masalah optimasi. Studi ini menggunakan sampel yang diambil dari google maps dan analisa deteksi kebutuhan pemeliharaaan jalan. Data yang diperoleh diolah dengan menggunakan perangkat lunak graph.ru.online dan Algoritma Kruskal serta Algoritma Prim. Hasil penelitian menghasilkan suatu pohon merentang minimum dari representasi graf kecamatan-kecamatan di kabupaten Karawang. Panjang jalan minimum untuk prioritas perbaikan jalan sepanjang 251 km.
