Abstract

The people of Moa Island have a cultural heritage in the form of Lutur Batu. Lutur Batu is a construction of large stones arranged side by side to form a circular wall. Lutur Batu is used to close village boundaries and as a garden fence which aims to protect plants from wild animals. This research aims to determine ethnomathematics studies on Lutur Batu on Moa Island. The ethnomathematics study of Lutur Batu on Moa Island in this research is expected to provide a deeper understanding of the local wisdom of the people of Moa Island, as well as contribute to the recognition, maintenance, and preservation of cultural heritage with mathematical value in the region. Furthermore, an understanding of the geometric patterns and construction of Lutur Batu can be adopted in mathematics learning at school to increase students' interest in learning and understanding of mathematical concepts.This qualitative research focuses on an in-depth understanding of ways of thinking and using mathematics in the traditions and practices of making Lutur Batu in Moa Island. The results of the analysis on Lutur Batu and the manufacturing process showed that there are mathematical concepts such as circles, cylinders, comparisons, and statistics. Lutur Batu and the Mathematical concepts contained therein can be used in Mathematics learning at school to enrich learning materials, increase learning motivation and students' understanding of Mathematics concepts. Apart from that, it can increase students' insight and knowledge regarding the cultural heritage of Moa Island

Abstract

The low mathematical literacy skills of junior high school students in Indonesia, especially those living in the Small Border Islands, require serious attention from various stakeholders. Improving students’ mathematical literacy is a shared responsibility that can begin with introducing the form of PISA mathematical literacy questions to junior high school students. One effort to achieve this is through an ethnomathematics-based mathematical literacy competition. This competition aims to provide knowledge and understanding of PISA mathematical literacy to students in the Small Border Islands, particularly on Moa Island. The activity was carried out as a form of community service by lecturers and students, consisting of four stages: initial observation, socialization, implementation, and evaluation. The participants of this competition were students from seven junior high schools on Moa Island, with a total of 57 participants. The increase in participants’ knowledge regarding PISA mathematical literacy question forms was measured using a questionnaire. The results showed an improvement in participants’ understanding before and after participating in the competition. However, test data also indicated that the mathematical literacy skills of students on Moa Island remain relatively low. Therefore, sustainable programs are needed to improve the mathematical literacy skills of students in the Small Border Islands, including Moa Island.
