Abstract

Abstract. The purpose of this study is to explore ethnomatematics in the activities of cocoa farmers to create the teaching materials for students in the form of the packages of test. The type of research was qualitative research with ethnographic approaches. The data collection method used were observation and interview. The research subjects were six people. The ethnomatematics included the activity of counting, measuring, and designing. This study focused on determining the estimated number of trees based on its distance and area by using stakes (patok), determining the fertilization model based on the fertilization time and the planting age, determining the number of workers based on the land area, and estimating yields. The emerging mathematical concepts were comparison and social arithmetic. Keywords: Ethnomatematics, cocoa farmers, culture

Abstract

Abstract: The purpose of this study is to describe the profile of algebraic thinking in junior high school students in solving mathematical problems in terms of cognitive style (reflective and impulsive). The subjects used were class VIII B Arjasa 1 Junior High School as many as 25 children. Data collection in this study used two test questions, namely the MFFT test (Matching Familiar Figure Test), algebra test and interviews with four students representing different cognitive styles (reflective and impulsive) . In this study students who have reflective cognitive style and students who have impulsive cognitive style can fulfill five indicators of algebraic thinking, namely generalization, abstraction, analytical thinking, dynamic thinking, and modeling. Kata Kunci: Algebraic thinking, Reflective Cognitive Style, Impulsive Cognitive Style

Abstract

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. Keywords: Ethnomatematics, Green Turtle, Fractal Dimension
