Abstract

Indonesia has been recognized by the world as a nation that has many uniqueness. One of the characteristics of the well-known Indonesian nation is batik. The aim of this study was to analyze how the patterns, symbols and mathematical motifs in North Nias batik are used and interpreted by Nias people in their cultural context. Almost all regions in Indonesia have typical batik which is a special characteristic of the area. Likewise with North Nias who recently launched Batik which is the hallmark of North Nias district, starting from the colors and also the motifs. North Nias batik motifs have unique patterns and if observed and analyzed have a relationship with mathematical concepts. The mathematical concepts that exist in North Nias batik motifs are related to congruence, flat shapes, geometric transformations. The research subjects could consist of North Nias traditional clothing makers, artists or Nias community leaders who have knowledge about the design and use of North Nias traditional clothing.

Abstract

The education system between Indonesia and Japan is different. The education system in Indonesia and in Japan has its own advantages and disadvantages. Currently, the education system in Indonesia needs more attention because it is ranked 72 out of 77 countries. In Indonesia, many educational experts have been born who are able to bring the education system in Indonesia to a better direction. One way to bring Indonesia's education system to a better direction is to compare it with a country with a good education system like Japan. In Japan, from the age of 0-4 years, children are more instilled with moral values, manners and discipline. When children in Japan have entered the 4th grade of elementary school, these children take exams that are not too burdensome for students at school. Indonesia can learn a lot with the education system in Japan.

Abstract

This study aims to determine the better improvement of students' mathematical connection and communication abilities between those participating in learning with the Discovery Learning model and those participating in direct learning, as well as to find out the differences in increasing the mathematical connection and communication abilities of students in high, medium and low groups who take learning with Discovery Learning models. Data analysis used a two-mean difference test to determine better improvement between the experimental class and the control class and one-way ANOVA with the Scheffe test to determine better improvement between the high, medium and low groups. Based on the results of the study, it can be concluded that the increase in the mathematical connection and communication skills of students who take part in learning with the Discovery Learning model is better than students who take part in direct learning. The improvement of students' mathematical connection and communication skills in the middle group was better than the high and low groups who took part in learning using the Discovery Learning model

Abstract

The current learning process requires teachers to provide opportunities for students to actively acquire their knowledge, thus requiring the support of interesting and innovative teaching materials that can deliver students to the learning information they want to learn, one of which is a learning website. In fact, mathematics teachers at SMA Negeri 2 Huruna still have difficulties in preparing teaching materials according to the needs and characteristics of their students due to limited time and abilities of teachers, so teachers still use teaching materials obtained from the internet in learning. This study aims to produce a product in the form of a learning website material for algebraic limit functions to help teachers facilitate student learning. The development model used in this study is the Borg and Gall development model, in this article it is only presented up to the design stage, namely by designing a learning website for material limits of algebraic functions based on the results of analysis at the research and data collection stages. The learning website was developed using Microsoft FrontPage software and provides several menus, namely: 1) Home, providing instructions for use and a brief description of the website; 2) KD and concept maps; 3) Material, containing learning videos, e-modules, as well as applications for processing learning outcomes; 4) Summary, presenting a summary/core of learning material; and 5) Design team, containing a brief profile of the learning website designer team.
