Abstract

The Asei people are known for their distinctive local cultural heritage, particularly in the form of carvings that decorate their house walls. These carvings serve not only as symbols of cultural and social identity but also contain visual structures rich in mathematical concepts. This study aims to explore and describe the mathematical elements found in the carvings of houses in the Asei community, located in East Sentani District, Jayapura Regency, Papua, as well as to examine their potential as a source for school mathematics learning. This research employs a qualitative approach using ethnographic methods. Data were collected through direct observation, in-depth interviews with two informants knowledgeable about the meanings of the carvings, and visual documentation. The collected data were analyzed through a continuous interactive process of data reduction, data presentation, and conclusion drawing. The results reveal that the carvings on Asei houses encompass various mathematical elements, including reflection, symmetry, rotation, dilation, as well as geometric shapes such as circles, triangles, parallelograms, trapezoids, parallel lines, obtuse angles, and acute angles. These elements are found within seven main carving motifs, namely kino, heuw, iuwga, me khela-khela, fouw, khaley, and kheika.

Abstract

This study aims to describe the implementation of the Jigsaw cooperative learning model in teaching algebraic factorization to eighth-grade students at SMP Negeri 1 Depapre, Jayapura Regency. Using a descriptive qualitative approach, this research examines the improvement in students' understanding and skills through expert and home group-based learning. Data collection was conducted through written tests and observations, focusing on student activity and instructional implementation. The findings indicate that the Jigsaw model significantly enhances student learning outcomes, achieving average scores above the minimum competency standards, along with positive changes in aspects of cooperation, responsibility, and student attitudes. This model is recommended for broader application to improve the quality of mathematics instruction in junior high schools.

Abstract

Penelitian ini bertujuan untuk meningkatan hasil belajar matematika peserta didik kelas X-E1-E1 SMA YPPK Teruna Bakti Jayapura melalui penerapan model pembelajaran kooperatif tipe Numbered Headss Together (NHT). Subjek penelitian ini adalah seluruh peserta didik kelas X-E1-E1 yang berjumlah 35 dengan jumlah peserta didik laki-laki sebanyak 16 orang dan peserta didik perempuan 19 orang. Penelitian ini merupakan Penelitian Tindakan Kelas (PTK) yang terdiri dari 2 siklus. Peneliti mengumpulkan data penelitian menggunakan lembar pengamatan dan lembar tes hasil belajar yang telah dianalisis. Berdasarkan lembar pengamatan pada setiap pertemuan menunjukkan bahwa adanya perbaikan proses pembelajaran dari pertemuan pertama pada siklus I sampai pertemuan terakhir pada siklus II. Selanjutnya dari hasil belajar peserta didik, terjadi peningkatan dari jumlah peserta didik yang mencapai KKM pada skor dasar yaitu 7 peserta didik atau 35%, sedangkan ulangan harian I yaitu 9 peserta didik atau 45%, dan ulangan harian II yaitu 13 peserta didik atau 65%. Berdasarkan rata-rata hasil belajar Peserta didik pada nilai dasar yaitu 52,65, ulangan harian I yaitu 58,45 dan ulangan harian II yaitu 71,1 sehingga dapat disimpulkan bahwa penerapan model pembelajaran kooperatif tipe Numbered Heands Together (NHT) dapat meningkatkan hasil belajar matematika peserta didik kelas X-E1-E1 di SMA YPPK Teruna Bakti Jayapura.

Abstract

This study analyzes the geometric concepts embedded in the rock painting motifs of the Tutari Megalithic Site, Sentani, and explores their potential as a resource for ethnomathematics-based mathematics learning. The limited use of local culture in mathematics education, particularly the underrepresentation of Papuan cultural heritage. A descriptive qualitative method with an ethnographic approach was employed. Data were collected through direct observation, visual documentation, literature review, and interviews with an Abuakho and a member of the Doyo Lama community. Data were analyzed using Spradley’s ethnographic model, including domain, taxonomic, and componential analyses. The findings indicate that the rock painting motifs contain various geometric concepts, such as circles, ellipses, triangles, rhombuses, semicircles, lines and angles. These results demonstrate that the motifs embody not only aesthetic and cultural values but also mathematical structures that can be interpreted through an ethnomathematical perspective. The identified concepts highlight the potential of local cultural artifacts as contextual learning resources for mathematics education in Phases B, C, and D of the Merdeka Curriculum.
