Abstract

Mathematical concepts that can be used to explore mathematics in culture. The term used to associate mathematics and culture is ethnomathematics. Cultural elements such as regional dances, regional songs, customs, regional languages, traditional games, traditional food and regional clothing need to be preserved because they can be integrated into the learning process. One of them is the culture found in the Batak tribe, especially the Batak Karo. The richness of the Batak Karo tribe in terms of traditional clothing motifs, namely the beka reed and uis nipes yeast western. The aim of this research is to explore the concept of flat shapes in the beka buluh and uis nipes ragi barat motifs of the Batak Karo tribe. The research was carried out in Tiga Binanga, Karo Regency, North Sumatra Province in December 2023 with sources from the traditional Batak Karo tribe. The data analysis used is observation and interviews. This research is qualitative research with an ethnographic approach. The results of this research found the mathematical concept of flat shapes in the motifs of beka buluh and uis nipes Ragi Barat Batak Karo tribe.

Abstract

The aim of this research is to determine the level of students' mathematical communication skills and emotional intelligence on student learning outcomes in mathematics learning. This research uses a quantitative type of research with one independent variable, namely emotional intelligence and one dependent variable, namely mathematics learning outcomes. The sampling technique in this research used purposive sampling so that the sample used was 60 students from class VI of SD Cenderamata. Data collection was carried out by means of literature study, distribution of emotional intelligence questionnaires and odd midterm exam (UTS) score data for the 2023/2024 academic year. Based on these data, it can be concluded that class VI students at Cenderamata Elementary School have relatively moderate emotional intelligence, meaning that the students' emotional intelligence is good. This is reinforced by the relationship between emotional intelligence and mathematics learning outcomes and that 17.24% of students' mathematical communication skills are in the high category with a frequency of 10 students, 70.69% are in the medium category with a frequency of 42 students and 12, 07% of students are in the low category with a frequency of 8 students. Based on these data, it can be concluded that class VI students at Cenderamata Elementary School have low mathematical communication skills. From the results it can be interpreted that there is a moderate relationship between communication skills and emotional intelligence on mathematics learning outcomes with the contribution of emotional intelligence to the high and low levels of mathematics learning outcomes of 31.6% and 68.4% were influenced by other factors outside the research.

Abstract

Mathematics learning that uses the circle concept using contextual concepts can make it easier for students to understand mathematical concepts and also broaden students' insight. This research aims to explore the shapes and patterns of Karo musical instruments, namely the gung and Penganak, which will then be used as material for developing learning resources based on the cultural diversity that exists in Tanah Karo. The method used in this research is exploratory with an ethnographic approach. The instrument used in this research is a human instrument, and the data collection techniques used by researchers are observation and documentation. From this research it was found that gung and penganak are flat, circular shapes which can be related to mathematics learning.

Abstract

This research aims to describe the relationship between creativity abilities and mathematical connections with high school students' learning achievement which is analyzed using correlation analysis. This research is quantitative research. The research population included all phase E class students at SMA Negeri 1 Salak. The sample was 146 students from 8 phase E classes determined by cluster sampling. Data collection was carried out using tests and questionnaires. The data analysis technique used is partial correlation analysis. The results of the research show that creativity abilities and mathematical connections are jointly related to high school students' learning achievement, where the contribution given is 46.3%, and the regression equation obtained is Y = 0.97 + 0.422X1 + 0.059 X2. The relationship between creative ability (X1) and learning achievement (Y) with a contribution of 23.27%. The relationship between mathematical connection ability (X2) and learning achievement with a contribution of 3.59%.

Abstract

The purpose of this study is to explore the integration of mathematics with culture through the traditional musical instrument of the Batak Toba ethnic group, one of which is the "garantung." This research employs a qualitative approach, gathering data through interviews and direct exploration of the garantung musical instrument. Data collection techniques involve observation, interviews, and documentation. The findings of this study reveal that the garantung musical instrument encompasses mathematical concepts, specifically in the realm of geometry, including plane and solid geometry. The garantung can serve as a tool to introduce mathematical concepts, such as geometric concepts, to learners, enabling them to better understand abstract mathematical ideas. Moreover, the garantung musical instrument can be utilized as a learning resource in educational settings. However, its usage has become increasingly rare within the context of modern musical development.Furthermore, there is a need for further research to develop mathematics teaching materials rooted in the Batak Toba culture, particularly focusing on the garantung musical instrument. This study highlights the potential for harmonizing traditional cultural elements with mathematical education, offering an innovative approach to teaching and learning that enriches both fields.
