Abstract

Ethnomatematics as link between culture and mathematics is a multicultural mathematical activity that uses culture in making connections with mathematics topics so as to motivate students to preserve their own culture while learning mathematics. The purpose of this reasearch are to explore ethnomathematics in Gajah Oling’s batik based on geometric concepts. The type of reaserch is qualitative with an ethnographic approach. Data collection methods used are observation and interviews. The subject of this reasearch is a design maker Gajah Oling’s batik. This research focuses on intersesting discovery from the exploration results, that is making pattern of Gajah Oling’s batik shirt. In the process of making pattern of Gajah Oling’s shirt, ethnomathematics seen on design and measuring activities. In desiging activities geometric concepts such as translation and reflection emerge, while in measuring activities, design makers use mathematics to determine the design size so that the fabric meeded to make a shirt can be minimized as little as possible.Keywords: Ethnomatematics, cocoa farmers, culture.

Abstract

Student worksheet based on Problem Based Learning (PBL) is a learning media that presents questions in the form of contextual problems so as to stimulate students' thinking skills. This type of research is development research using the Thiagarajan model or the Four-D Model which aims to describe the process and results of developing PBL-based student worksheets for class VIII students on Prism material that is valid, practical, and effective in training students' creative thinking skills. The method used in this research is the questionnaire method to determine the validity and practicality of the student worksheets and the test method to determine the effectiveness. The results of this study are the achievement of increasing students' creative thinking skills with very good interpretations. The student worksheets based on PBL model on prism material produced were declared valid, practical, and effective. This student worksheet could be used to improve students' creative thinking skills.

Abstract

Ethnomatematics is the practice or daily activities of a society that has become a culture and there is the application of basic mathematical concepts. The purpose of this research is to describe ethnomatematics on the activities of hatching process of semi-natural green turtle eggs in Sukamade, Meru Betiri National Park to make teaching materials for students in the form of test questions and calculate the fractal dimensions on sand used for hatching the eggs of green turtle. This type of research is qualitative research with an ethnographic approach. The data collection methods used are observation and interviews. The research subjects were the UPKP (Turtle Conservation Management Unit), MMP (Gamekeeper Partner Community) and Facilitators. This study focuses on the activities to calculate, measure, and design. The mathematical concepts that arise are arithmetic operations, value comparisons, arithmetic series and geometric shapes. Fractal dimension calculations on natural and semi-natural sand in the process of hatching green turtle eggs with MATLAB aid program obtained the fractal dimensions on natural sand was 1.7252 and on semi-natural sand was 1.7273.
