Tebing Tinggi City, which has a strategic position in North Sumatra, is experiencing changes in population growth that need to be predicted for development planning purposes. The purpose of this study is to forecast the population of Tebing Tinggi City in 2030 by applying the Double Integral method, and visualize the results in 3D using GeoGebra. The method used is a quantitative approach with a case study, where the population density function is created based on secondary data from the Central Statistics Agency (BPS) of Tebing Tinggi City for the period 2010 to 2024. Data on area and population per sub-district are used to develop a population growth model calculated using the double integral. The forecast results show that the population of Tebing Tinggi City is estimated to reach 26,038 people in 2030, with varying growth rates in each sub-district. 3D visualization through GeoGebra is able to depict the distribution of population density in an interactive geometric form, thus facilitating the understanding of complex mathematical concepts. The conclusion of this study is that double integrals can be applied effectively to predict population size, and GeoGebra serves as a very useful visual aid in presenting the results of multivariable calculus analysis.

This research is a development study that aims to create a product in the form of a learning aid, namely audio-visual media through the GeoGebra Classic application, which is used for 3-dimensional geometric shapes lessons in grade V of YPNU Elementary School Medan. This research was conducted because teachers still do not utilize technology optimally in teaching, especially in mathematics subjects related to spatial shapes. The lack of engaging and interactive teaching methods for complex topics like 3D geometric shapes often leads to reduced student interest and understanding. To improve the mathematics learning process on the topic of spatial shapes, audio-visual media was created with the help of the GeoGebra Classic 5 application. The goal is to provide variations in mathematics learning media and increase student interest in the lesson. The development of this media allows students to visualize 3D geometric shapes more clearly and interactively. The instrument used to collect data was a questionnaire that included questions to assess the effectiveness of the media from the perspective of educators and students. The results of the evaluation revealed that learning using this media received 93% responses from teachers and 87% from students, which indicates that the media is very effective. The positive feedback from both groups suggests that this audio-visual tool can enhance students' understanding of spatial geometry concepts and improve the overall learning experience. This study offers an innovative approach to teaching mathematics and highlights the importance of integrating technology into the classroom to foster better engagement and learning outcomes.

This study is a literature review that aims to identify and analyze the application of GeoGebra applications in learning geometric transformations at the high school level. Geometric transformation is a material that requires high spatial visualization skills, so learning media are needed that are able to present concepts in a concrete and interactive way. GeoGebra, as a dynamic mathematics application, is considered capable of facilitating student understanding through direct visualization of transformation processes such as translation, reflection, rotation, and dilation. The study was conducted by reviewing 11 relevant scientific articles, published in the last five to ten years, and meeting certain inclusion criteria. The results of the analysis show that the application of GeoGebra in learning has a positive impact, both cognitively, affectively, and technically. GeoGebra is able to improve students' understanding of concepts, learning motivation, and learning outcomes. The implementation strategy includes the development of e-modules, digital teaching materials, problem-based learning, and application usage training. Overall, GeoGebra has proven to be valid, practical, and effective in supporting more interesting and meaningful learning of geometric transformations.

A parabola is a curve that consists of points that are equidistant from a fixed point (focus) and a fixed line (directrix). This study aims to analyze the shape of the canopy roof of the UBB Medical Building using an analytical geometry approach on parabolas. The method used is a quantitative descriptive based on visual documentary online and proportional estimates against comparative objects. The parabola model is constructed from three key points and visualized using GeoGebra. The results show that the shape of the canopy can be accurately represented through the equation of a parabola, with a symmetrical and aesthetic structure. This research proves that mathematical concepts can be practically applied in architectural design.
