Abstract

Regency, which functions to preserve the sustainability of the coastal environment and prevent the overexploitation of lompa fish resources (Thryssa baelama). This literature study examines the practice of Sasi Lompa from an ethnomathematical perspective to reveal how mathematical concepts are integrated into cultural activities. The results of the analysis indicate that the Sasi procession reflects the application of arithmetic operations, such as counting the members of the kewang, the symbolic five beats of the tifa drum, the calculation of the closing and opening time cycles of Sasi, and the determination of the restricted area. The harvest- sharing mechanism also contains mathematical elements through proportional distribution, where 30% of the catch is allocated to vulnerable community groups. In addition, the implementation of customary sanctions in the form of symbolic punishments demonstrates the use of simple mathematical calculations within the social control system. From a geometric perspective, Sasi attributes such as woven young coconut leaves and the wooden Sasi marker represent plane geometric shapes (square, rectangle, rhombus, and semicircle) as well as three-dimensional shapes (the cylindrical form of the tifa drum). These findings confirm that ethnomathematics is contextually embedded in the Sasi Lompa tradition, which not only functions as a customary-based conservation instrument but also has the potential to be integrated into school mathematics learning. Therefore, this study contributes to the development of a local culture–based curriculum, strengthens cultural identity, and fosters ecological awareness among the younger generation

Abstract

Penelitian ini bertujuan untuk mengkaji unsur-unsur matematika yang terkandung dalam proses pembuatan krupuk dari singkong melalui pendekatan etnomatematika, serta menganalisis potensi penggunaannya sebagai sumber pembelajaran matematika yang kontekstual. Penelitian ini menggunakan pendekatan kualitatif deskriptif dengan metode observasi, wawancara, dan dokumentasi terhadap pelaku UMKM dan masyarakat lokal yang masih memproduksi Kerupuk Singkong secara tradisional. Data yang diperoleh dianalisis untuk mengidentifikasi keterkaitan antara aktivitas budaya tersebut dengan konsep matematika dalam kurikulum sekolah dasar dan menengah. Hasil penelitian menunjukkan bahwa kegiatan produksi Kerupuk Singkong memuat sejumlah konsep matematika yang aplikatif, seperti pengukuran volume dan massa bahan, perbandingan rasio campuran, penggunaan alat ukur tradisional, serta pengaturan bentuk dan ukuran krupuk. Aktivitas-aktivitas ini memiliki potensi besar untuk diadaptasi menjadi media atau konteks pembelajaran matematika yang lebih relevan dan bermakna bagi siswa. Kajian ini merekomendasikan pengembangan bahan ajar berbasis budaya lokal untuk meningkatkan pemahaman konsep matematika dan mendorong pelestarian kearifan lokal melalui pendidikan.

Abstract

Mathematics in school is often viewed as abstract and less relevant to students' daily lives. Therefore, a contextual approach is needed that connects mathematical concepts to the local culture of the community. This study aims to examine ethnomathematics in aluminum kitchenware crafts in Ohoitahit Village, Tual City. This study uses a qualitative method with an ethnographic approach to uncover the mathematical concepts integrated into the practice of making traditional kitchenware. The results show that the Ohoitahit community intuitively applies mathematical activities such as counting, localizing, measuring, designing, playing, and explaining in every stage of production. This mathematical knowledge is passed down orally and empirically, becoming an integral part of the community's culture. This study emphasizes the importance of ethnomathematics as a tool for understanding local wisdom and developing more relevant and contextual mathematics education.
