Abstract

This study aim to produce teaching materials for geometry modules in lato-lato games to understand the material of lines and angles in terms of validity, practicality and effectiveness. This type of research is Research and Development (R&D), using the ADDIE (Analysis, Design, Development, Implementation, and Evaluation). The results showed that the media expert's validation score obtained a score of 83.3% from validator 1 and 81.6% from validator 2, both of which indicated very valid categories. The material expert validation score obtained a score of 83.3% from validator 1 and 80% from validator 2, both of which indicated very valid categories. The validity value was also obtained from a small-scale trial, namely the student response questionnaire which obtained a score of 86.4% in the very valid category and the mathematics teacher's response questionnaire obtained a score of 91.2% in the very valid category. While the practicality score obtained a score of 86.5% from the student response questionnaire, 87.5% from the teacher response questionnaire and 94% from the module implementation observation sheet, all three of which were included in the very practical category. The value of effectiveness is obtained from the results of student tests. Student test scores after using the module during learning get a percentage score of 80% which states that it is classically complete. Thus, the module has fulfilled the aspects of validity, practicality and effectiveness and can be used in the learning process.

Abstract

Ethnomathematics is a field of study that connects mathematical concepts with cultural practices that develop within community life. This study aims to explore the mathematical concepts embedded in post-harvest tobacco activities of the Pandalungan community in Sumber Kalong Village and to develop an ethnomathematics-based Student Worksheet on the topic of direct proportion. This research employed a qualitative method with an ethnographic approach. The research subjects consisted of five tobacco farmers involved in the post-harvest tobacco processing activities and students of MTS Nurul Huda, most of whom come from tobacco-farming families. Data were collected through field observations and in-depth interviews with the farmers. The results of the study show that post-harvest tobacco activities in the Pandalungan community contain various mathematical concepts, particularly in activities related to counting, measuring, and designing. The mathematical concepts identified include direct and inverse proportion, measurement of length and distance, and numerical operations in calculating the fermentation and drying time of tobacco. The concept of direct proportion appears in determining the number of tobacco leaves in certain weight units and in arranging the drying patterns of tobacco leaves. Based on these findings, ethnomathematics-based teaching materials in the form of Student Worksheets (LKS) were developed to assist seventh-grade junior secondary school students (SMP/MTs) in understanding proportional concepts contextually through local cultural activities of the Pandalungan community.
