Abstract

Penelitian ini bertujuan untuk mengeksplorasi konsep etnomatematika yang terdapat dalam budaya penangkapan ikan paus dan sistem barter masyarakat Lamalera, Kabupaten Lembata. Pendekatan yang digunakan adalah deskriptif kualitatif dengan metode observasi, wawancara, dan dokumentasi. Hasil penelitian menunjukan menunjukan bahwa dalam proses penangkapan ikan paus, masyarakat menggunakan alat-alat tradisional yang memiliki bentuk geometris, seperti perahu (trapesium), layar (persegi panjang), tombak (segitiga), dan Gong (lingkaran). Selain itu, saat melempar tombak, juru tikam mempertimbangkan sudut dan jarak, yang mencerminkan konsep sudut dan estimasi. Dalam sistem barter, masyarakat Lamalera menerapkan konsep aritmatika sosial secara tidak langsung, seperti perbandingan nilai tukar, perhitungan jumlah hasil laut dan hasil pertanian yang dipertukarkan.

Abstract

The aim of this research is to develop a School Mathematics Study module based on Problem Based Learning that is valid and effective. This Problem Based Learning-based module emphasizes problem solving in understanding mathematical concepts. The School Mathematics Study Module based on Problem Based Learning refers to the 4D development model, which is only limited to the Develop stage. The data collection instrument consists of a validation sheet and problem solving test questions. The trial was carried out on students of the Universitas Insan Budi Utomo Mathematics Education study program who were taking the School Mathematics Studies course. The results of data analysis show that the module fulfill the criteria for validity and effectiveness. Expert validation and module testing. From the assessment results from two experts, an average score of 3,2 was obtained, which is a very valid criterion.
