Abstract

Digital maps are representations of geographic phenomena stored for display and analysis by computers. A digital map can also be interpreted as a digitally presented image of the earth's surface that is reduced to a certain scale through a projection system. Digital geological mapping using smartphones is increasingly popular because it provides many conveniences. The purpose of this paper is to discuss which smartphone (smart phone) based operating system is the best in terms of accuracy for digital geological mapping. The market share of smartphones is currently controlled by three big players, namely Android, Windows and IOS. The results of a literature search show that there are two most popular operating systems for digital geological mapping, namely Android and IOS. Based on the review results, even though Android has the largest market share, iOS-based smartphones have various advantages in terms of reliability and accuracy.

Abstract

The application of GeoGebra in teaching still faces challenges such as teacher readiness and the availability of technology in schools, especially in mathematics learning. This research examines the correlation of the GeoGebra application to the mathematics learning outcomes of students whose learning uses the Realistic Mathematic Education learning model. This research was conducted at SDN 074 Ayudia, Bandung City using quantitative methods with a non-experimental approach. The population in this study were all students at SDN 074 Ayudia with a sample of 27 students in class VI B and the instruments used were questionnaires and tests. The sampling technique was carried out using a probability sampling technique based on cluster sampling. Meanwhile, the swimmer test from the data analysis carried out was a normality test using Kolmogorov-Smirnov assisted by the SPSS application. In this research, it can be concluded that there is no significant correlation between the application of Geogebra to the mathematics learning outcomes of students whose learning uses the Realistic Mathematic Education (RME) model, and the correlation is classified as very low. For further research, it is hoped that we can use other learning models to see the influence that occurs between the application of the Geogebra application in mathematics learning to see special equations in simple linear regression to be able to know the probability of the independent variable and the dependent variable.
