Abstract

Learning mathematics is sometimes monotonous and boring. For this reason, teachers are required to be able to create interesting and not boring learning media that can increase students' interest in learning mathematics. One of the learning media that can attract students' interest is making a video for learning mathematics to calculate distance units that are integrated with the local culture of the Kesepuhan Cirebon palace. With this learning video, it is hoped that students will be interested in participating in mathematics learning and getting to know the local culture, so that student learning achievements can increase. The research method used is the descriptive qualitative method. Data was collected using interview techniques, offline learning observations, and school documentation, data analysis was carried out using interactive analytical techniques consisting of three steps, namely data reduction, data presentation, and drawing conclusions. From the results of the study, it was found that the innovation of learning media videos to calculate distance units that were integrated with the local culture of the Kesepuhan Cirebon palace was able to increase student interest in learning and student achievement, this can be seen from the ability of students to convert distance units from places in the Kesepuhan palace, Cirebon.

Abstract

The objective of the study is to explore and find out the ethnomathematics of Gedongsongo Temple, located in Central Java, Indoensia. The type of study is qualitative with an exploration way and ethnographic approach. The data obtained in the form of qualitative data, the source of research data obtained through observation, interviews, documentation, and study of literature related to Gedongsongo Temple. The data collection technique was done by questioning, observing, interviewing, and documenting. The results showed that the ethnomathematics of Gedongsongo Temple has the potential to be integrated into mathematics learning. Ethnomathematics that can be integrated includes the concept of flat area, volume of space,  comparison/ratio, reflection, and symmetry. The flat-geometry concept is found in the several parts of Gedongsongo Temple including square, rectangle, triangle, and trapezoid. The spatial-geometry concept is also found in several parts of Gedongsongo Temple including cubes, blocks, tubes, and a triangle prism. Meanwhile, the comparison/ratio concept found is the Golden Ratio on the fore-temple of Perwara in the area of Candi Gedong III. The symmetry and reflection concept is found in Candi Gedong I. These concepts can be applied in mathematics learning as a contextual geometry problem as well as a way of introducing cultural elements to students.

Abstract

Education and culture that exist in everyday life are closely related. In order to bridge the gap between culture and education, especially mathematics education, there is ethnomathematics. The existence of mathematics is inherent in everyday life, but many people are not aware of it. Examples of daily activities that contain elements of mathematics are calculating the price of groceries, and calculating the area and volume of certain buildings. The purpose of this study is to explore and describe the ethnomathematics of Cetho Temple and to examine the plane figures related to the basic competencies of fourth grade mathematics learning for elementary school students. This type of research is descriptive qualitative with data collection methods using observation, interviews, and documentation. Data analysis activities started from the instrument validation test, reduction, data presentation, and drawing conclusions. Triangulation technique was used to reduce bias during data analysis. The results showed that at Cetho Temple there was a geometric concept. The part of the temple that contains the concept of geometry, namely the statues, reliefs, and other important parts. The concept of geometry consists of the concept of the plane figures, spatial, polygonal, similar, and reflection. Based on these findings, the study focused on the flat structure material related to the basic competencies of fourth grade mathematics learning for elementary school students.

Abstract

This study aimed to explore mathematical comics learning media through Instagram social media with the theme of local culture as an alternative learning solution that is feasible to use in terms of validity, practicality, and effectiveness. This study used the ADDIE development model. Analysis, to determine the problem and solution. Design, that is designing learning materials and objectives; sketching names, figures, and characters; compiling a script; making a storyboard; creating Instagram feed content. Development is the process of finishing the manufacture of products. The implementation of the product validation test was carried out by two experts in mathematics education and tested by students and teachers in a Junior High School in Salatiga. Evaluation is carried out as the final version of the material for further research based on teacher and student responses. Data collection methods in this study are observation, interviews, questionnaires, literature study, and documentation. The results showed that comics with local characters can engage students in learning mathematics. First, they might be interested to know the local culture and then were realized mathematical thinking. The data showed an average validity of 4.15 with a valid category, average practicality of 4.27 categorized as practical, and an average evaluation test obtained a result of 8.5 so it was categorized as effective on student learning outcomes. Therefore, when creating comics for learning in social media, using local culture is suggested.

Abstract

This article aimed to describe the results of the ethnomathematical exploration of traditional musical instruments that can be used as mathematics teaching materials. The research method chosen in this study was the Systematic Literature Review (SLR) method. The SLR method is used to identify, review, evaluate, and interpret available research with areas and topics of interest. Data collection is done by documenting and reviewing all articles related to ethnomathematics on traditional musical instruments, selecting only those using Indonesian traditional instruments, and publishing them in Indonesian national journals. It was found that 10 articles matched these criteria. The results showed that ethnomathematics-based mathematics learning on traditional musical instruments can be used in the learning process and can be used as a learning resource, a means of introducing mathematics through culture, implemented in mathematics learning, and as teaching materials in learning mathematics. The uses in learning can be the shapes of the instruments as well as how to play the instruments that yield number patterns.
