Abstract

Etnomatematika adalah suatu ilmu matematika yang mempelajari tentang budaya. Salah satu aktivitas budaya yang mengandung konsep matematika yaitu perhitungan hari baik suku melayu pulau jaloh, Kepulauan Riau. Seperti penentuan hari baik untuk nelayan mencari ikan ke laut, menentukan waktu pernikahan dan perlombaan yang akan diadakan masyarakat. Tujuan Penelitian ini adalah melestarikan budaya suku melayu dan mengeksplorasi etnomatematika pada kepercayaan penentuan hari baik di Pulau Jaloh. Metode yang digunakan pada penelitian ini adalah metode kualitatif dengan pendekatan etnografi. Penelitian ini berlokasi di Pulau Jaloh, Kepulauan Riau. Teknik pengumpulan data yang digunakan adalah observasi dan wawancara langsung kepada narasumber penelitian yang lebih mengetahui dan memahami secara mendalam mengenai penentuan hari baik di Pulau Jaloh. Hasil penelitian menunjukkan masyarakat Pulau Jaloh menggunakan konsep matematika berupa konsep pola bilangan atau barisan bilangan dalam penentuan hari baik untuk nelayan mencari ikan ke laut, menentukan waktu pernikahan dan perlombaan yang akan diadakan masyarakat. Hasil ini dapat disosialisasikan dan dimanfaatkan sebagai sumber pembelajaran kontekstual.   Kata kunci: Eksplorasi, Etnomatematika, Kepercayaan Hari Baik, Pulau Jaloh Abstract: Ethnomathematics is a mathematical science that studies culture. One of the cultural activities that contains mathematical concepts is calculating the good days of the Malay tribe on Jaloh Island, Riau Islands. Such as determining good days for fishermen to fish in the sea, determining the time of weddings and competitions that will be held by the community. The aim of this research is to preserve the culture of the Malay tribe and to explore ethnomathematics in beliefs about determining good days on Jaloh Island. The method used in this research is a qualitative method with an ethnographic approach. The location of this research is on Jaloh Island, Riau Islands. The data collection techniques used were direct observation and interviews with research sources who knew and understood more deeply about determining a good day on Jaloh Island. The results of the research show that the people of Jaloh Island use mathematical concepts in the form of number patterns or number sequences in determining good days for fishermen to fish in the sea, determining the time of weddings and competitions that will be held by the community. These results can be dissocialized and used as a contextual source of learning. Keywords: Exploration, Ethnomatematics, Good Day Beliefs, Jaloh Island

Abstract

The failure of students to solve unstructured mathematical problems is a common issue in the learning process. The purpose of this study is to explore the causes of students’ failure to solve unstructured mathematical problems. This study employed a descriptive qualitative approach. The research subjects consisted of 47 mathematics education students, with 6 students—comprising first-, third-, and fifth-semester mathematics education students from the University of Riau Islands—serving as the primary subjects for interviews. Data collection techniques included a written test in the form of unstructured problem-solving questions, interviews, and observations. The test instrument was validated through expert validation to ensure the appropriateness of the mathematical problem-solving indicators. The data analysis in this study followed the framework of Miles and Huberman, which includes data reduction, data presentation, and drawing conclusions. The results of the study indicate that first-semester students predominantly struggle at the stage of understanding and representing problems, while upper-semester students tend to have weaknesses at the stage of evaluating and reflecting on problems. Additionally, students’ failures are influenced by their continued reliance on routine problems, their tendency to use a single algorithmic solution strategy, and their failure to evaluate and reflect on the results of problem-solving.
