Abstract

Ethnomathematics is the study of how a group of individuals in a particular culture understand, communicate, and use cultural ideas and practices that researchers identify as mathematics. To return cultural heritage of traditional house in Batam, Riau Islands, and to further explore the idea of mathematical geometry inherent in the traditional house, so this research aims to explore the ethnomathematics in the Malay Traditional House 'Limas Potong'. This study applied a qualitative approach that was conducted in the Malay Traditional House 'Limas Potong', specifically in the Kampung Melayu neighborhood of Batam City's Nongsa District in the Riau Archipelago. The data used in this research was obtained from these explorations or already-published articles. Observation, interviews, and documentation were used as data collection methods. In this research, data analysis was carried out in two stages: data analysis in the field and data combining. According to the research findings, each decorative and structural part of the Malay Traditional House 'Limas Potong' incorporates mathematical ideas in geometrical shapes and components. Measurement, architectural design, mathematics learning, and application of learning are all related to ethnomathematics in the Malay Traditional House 'Limas Potong'. The construction of the Malay Traditional House 'Limas Potong' can be utilized as a learning resource for students, especially in geometry material, according to some mathematical ideas contained in the structure of the traditional house. Ethnomathematics exploration will inspire teachers to make this a new alternative to developing creativity in students' mathematics learning.

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
