Augmented Reality assisted by GeoGebra 3-D for geometry learning W. Widada, D. Herawaty, K. U. Z. Nugroho, A. Anggoro Journal of Physics Conference Series, 2021 Geometry becomes a difficult subject for students. The abstract object was one of the factors. Therefore, more concrete learning media are needed. One of them was augmented reality assisted by GeoGebra. The purpose of this study was to determine the ability to understand the geometrical concepts of high school students through augmented reality learning assisted by GeoGebra. Treatment was given to students through learning using GeoGebra-assisted augmented reality. This was a quasi-experimental study with a pre-test post-test control group design. This research instrument was a test of the ability to understand the concept of geometry. The test was used to measure students’ initial abilities, and this was referred to as a covariate. Also, to measure the ability to understand concepts after students follow augmented reality learning assisted by GeoGebra. Data were analyzed by covariate analysis (ANCOVA). The results of this study were F = Fo (A) = 9,150 with p-value = 0,000 <0,005. That means, there are differences in the ability to understand the concept of geometry between those taught with augmented reality which is assisted by GeoGebra and conventional learning. Other results show that t = 6.723 with p-value = 0.000 <0.05. This shows that the ability to understand the geometry concepts of students taught with augmented reality assisted by GeoGebra was higher than students who were taught conventionally after controlling for covariates. The conclusion was that the ability to understand the concepts of geometry through GeoGebra-assisted augmented reality learning was better than students taught with ordinary learning.
The ability to solve mathematical problems through realistic mathematics learning based on ethnomathematics A. Lubis, W. Widada, D. Herawaty, K. U. Z. Nugroho, A. Anggoro Journal of Physics Conference Series, 2021 Problem-solving is one of the goals of mathematics learning. Ethnomimetic-based realistic mathematics learning is learning with starting-point contextual problems that are close to students’ minds. This study aims to determine the effect of ethnomathematics-oriented realistic mathematics learning on problem-solving abilities. That is a type of quasi-experimental research. The study design was a non-equivalent control group. The population is SMA N 2 Kota Bengkulu in 2019. The sample of this study was 68 students from Class X MIPA A and X MIPA D. The research instrument was a test of problem-solving skills. Data were collected through tests and analysed by covariate analysis. The results of this study are that realistic mathematics learning oriented to ethnomathematics has a positive effect on the ability to solve. The conclusion is that realistic mathematics learning with ethnomathematics orientation can improve mathematical problem-solving skills for secondary school students. We suggest that mathematics teachers can develop realistic mathematics learning tools with ethnomathematics as a starting point for learning.
The exploration of the elementary geometry concepts based on Tabot culture in Bengkulu N. Agusdianita, W. Widada, N. Afriani, H. Herawati, D. Herawaty, K. U. Z. Nugroho Journal of Physics Conference Series, 2021 Geometry’s direct objects were abstract. It was a learning material that was difficult for elementary students. Therefore, learning was needed close to the minds and daily lives of students. One of them was “Tabot” Culture. That was the ethnomatematics approach. The purpose of this research was to explore elementary geometry concepts based on Tabot Culture. We apply an explorative-qualitative approach. The subjects of this study were the makers of the Tabot, elementary students, and elementary mathematics teachers. This was a needs analysis. Activities were carried out through direct observation, documentation, in-depth interviews and focus group discussions. The research instruments were anecdotal direct observation sheets, and interview guides. Data were analysed qualitatively. The results of the study found that the culture of Tabot provides reinforcement of student character that was obeying the principle, thinking logically, critically, working hard, curiosity, independence, confidence. The geometrical concepts that exist in the Tabot culture were the cube, the beam, the pyramid, the prism, the sphere and its elements. Also, understanding of two-dimensional figure. We conclude that Bengkulu Tabot culture can be used as a starting-point for learning the achievement of geometrical concepts and strengthening student character.

The subjects were junior high school students selected based on their ability to understand concepts and principles about quadratic equations. That’s done through tests about understanding quadratic equations. There were 16 selected research subjects. They were interviewed in-depth by researchers using interview guides. Interview data were analyzed qualitatively based on genetic decomposition. The results of this study are that students can use square, rectangular and unit square cards to determine the principle of factorization of quadratic equations. Students can generalize until completing a perfect quadratic equation. The conclusion is that the cognitive process of students who learn to use learning media based on square and rectangular able to reach a high level (trans-level).
The understanding of the triangle in Lobachevski geometry through local culture W Widada, D Herawaty, I Hudiria, Y A Prakoso, Y R Anggraeni, K U Zaid Nugroho Journal of Physics Conference Series, 2020 A triangle is an abstract object in Lobachevsky’s Geometry. The local content is needed as a starting point for learning geometry. This study aims to describe student’s understanding of triangles in Lobachevsky Geometry through local culture. This is an exploratory study. The focus is on analyzing the needs of student’s ability to understand the properties of Lobachevsky’s geometry. The subjects of this study were mathematics education students in Bengkulu, Indonesia. In-depth interviews are based on assignments about triangular problems. The problem is taken from the culture of Bengkulu society about “glutinous rice cake”. Data were analyzed through a collection of interviews and other physical activity. The results of this study are the subjects can connect the elements together to form a coherent unity based on observations of sticky rice cake. They produced a new product by organizing several elements into different forms or patterns from before, namely triangles with a large number of angles of less than 180. The conclusion of this study is that student’s understanding of triangles in Lobachevsky Geometry has reached the level of creating a new proposition, namely the number of angles in triangles in Lobachevski Geometry is less than 180.
Multiplication and division of integers through cultural approaches of playing dakon W Widada, D Herawaty, Y Pusvita, D Anggreni, R Aripianti, B Panduwinata Journal of Physics Conference Series, 2020 Playing dakon has become a culture in Bengkulu. Since I was in kindergarten, dakon has been a fun game. It has the character of sharing fruit in each dakon convex (or hole). It becomes the starting-point of learning multiplication and division. The purpose of this study was to determine students’ thought processes in understanding the principle of multiplication and the division of integers through the cultural approach to playing the dakon. To achieve the goal, achieved through qualitative-explorative research. The subjects of this study were elementary students in Bengkulu City who were selected based on assignments. It was selected from 30 students who were given assignments about multiplication and division of integers. Students are given instructions using worksheets. After students submit their assignments, they are analyzed to select 2 students who have the thought process in achieving the principle of division and multiplication appropriately. Subjects were interviewed in-depth by researchers. Data were analyzed based on the genetic decomposition of research subjects. The results of this study are the Subject-1 can use the dakon to show the multiplicative properties of positive integers. He demonstrated that 4x3 by inserting it into four small dakon curves and three dakon seeds each. She concluded that multiplication is a repeated sum. Subject-2 uses the dakon to find the concept of dividing two positive integers. Subject-2 shows that 12: 4 by taking dakon seeds from a large curvature containing twelve seeds. She concluded that the division is a repeat reduction. This research concludes that Subject-1 and Subject-2 can build an understanding of operations multiplication and division, including verbal communication, writing, and drawing based on real media from local culture, namely the dakon game.
