Abstract

The main focus of this research is to identify geometric patterns that may be hidden within the dimensions, shapes, and orientations of the dolmens. Overall, the objective is to identify, analyze, and understand the ethnomathematical concepts embedded in the dolmens at the Duplang Site. The specific aims include documenting the dimensions, comparing them with other sites, and interpreting their cultural significance. This study employs a qualitative descriptive method with an ethnographic approach. The research methods involve direct observation, documentation, interviews, visual analysis, and precise measurements using a measuring tape. The outcomes of this exploration are expected to make a significant contribution to our understanding of the cognitive abilities of prehistoric communities. The main outputs include a comprehensive research report and the identification of unique mathematical patterns such as hidden geometries

Abstract

This study aims to describe the form of ethnomathematics contained in patrol music as one of the local cultural heritages of the Jember Regency community. This study uses a qualitative descriptive approach with data collection techniques through observation, interviews and documentation of local cultural actors. Based on the results of data collection, several traditional Jember musical instruments were obtained, namely kentongan, tambourine and flute. Based on the results of the exploration, it was found that there are mathematical concepts contained in the kentongan, tambourine, and flute musical instruments including size and measurement, spatial shapes, rhythmic patterns, rhythm and time, symmetry. Kentongan and tambourine are rhythmic musical instruments that use the concept of counting and patterns to create rhythm and beats. Meanwhile, the flute utilizes the concept of frequency and wavelength to produce different tones, which are also related to mathematics.

Abstract

One of the activities that helps the teaching and learning process (KBM) is the process of providing interesting practice questions, one of which is with educational games. This research is development research that aims to produce valid, effective, and practical learning media. This research is development research, or research and development (RD), with the ADDIE development model, which consists of analysis, design, development, implementation, and evaluation. The resulting product is CATMOD (Modified Chess), a medium that is basically chess, then designed to be used as a learning medium, especially for linear equation material. CATMOD has been declared valid from the material aspect and the learning media aspect with consecutive scores of "4.33" and "4.14," both of which are included in the valid category. CATMOD has been tested on class VIII A Nurul Imam Randuagung students and produced a practicality index of use of "2.7," which is included in the good category. Furthermore, the posttest test with an average of 90.2 showed that there was an increase in student learning outcomes from before and after using the media. Based on these three results, it can be concluded that this medium is valid, practical, and effective.
