Abstract

The subject of Natural Sciences plays a crucial role in Elementary School Education. One of the topics covered in elementary school Natural Sciences is the circulatory system. The topic of the circulatory system in Natural Sciences can be studied extensively, particularly focusing on the closed or double circulatory system. The circulatory system is one of the challenging topics for elementary school students to understand and absorb, especially in Grade V. Some elementary school students may also struggle to comprehend the structure of the circulatory system in humans, particularly the cardiovascular system from the top or bottom. There are many tools that assist students in learning a particular subject. One useful tool for learning Natural Sciences is interactive media. This research involves the development of interactive media using the ADDIE method (Analysis, Design, Development, Implementation, and Evaluation). This paper explains the ongoing development process.

Abstract

Educational games have developed as a promising alternative to traditional learning approaches and are now widely used in various educational settings. Empirical research has demonstrated that adopting educational games as educational tools improves students' learning and motivation, especially in mathematics. This study aims to design and develop an educational game for elementary school mathematics learning, especially the topics of Least Common Multiple (LCM) and Greatest Common Divisor (GCD). For this purpose, we apply the Multimedia Development Life Cycle, which consists of six steps: concept, design, material collecting, assembly, testing, and distribution. The game was developed by using the Unity game engine and tested using black box testing. As a result, all the primary functions in the game were valid. For future studies, we intend to conduct user studies with elementary students.

Abstract

Completing the study plan card (KRS) is one of the most important processes in lectures. The problem that is often faced by first year students when doing KRS is that students do not know the steps for doing KRS. This paper proposes a simulation game as a solution to solve this problem. The focus of this paper is to explain the development process and the results that have been achieved. Game development is done using the ADDIE model. Game evaluation is done by using black box testing. Based on the black box test results, all game functionality can run. Therefore the game can be used for user testing

Abstract

Autonomous path planning for Unmanned Aerial Vehicles (UAVs) plays a critical role in applications ranging from disaster response to urban logistics. Traditional algorithms, such as A*, are widely recognized for their reliability in generating collision-free and efficient trajectories but often struggle with scalability in complex and dynamic environments. This study evaluates the performance of several neural network architectures, including MLP-LSTM, CNN-GRU, CNN-LSTM, CNN BILSTM, and others, as potential alternatives to classical methods. A dataset of trajectories generated by the A* algorithm was used to train and benchmark the models, enabling direct performance comparison across key metrics such as path length, smoothness, clearance, collisions, and waypoint density. The results demonstrate that the MLP-LSTM model outperforms other neural architectures, producing paths that closely resemble A* trajectories with high smoothness and waypoint granularity. While some models, such as CNN-GRU and CNN-BILSTM, show promise in generating feasible paths, their performance is inconsistent across different UAV scenarios. Models like Residual CNN and Hybrid CNN-MHA failed to generate meaningful trajectories, highlighting the critical importance of architectural choices. This study underscores the potential of neural network models for UAV path planning.

Abstract

Unmanned Aerial Vehicles (UAVs) have emerged as vital tools in diverse applications, including disaster response, surveillance, and logistics. However, navigating complex, obstacle-rich 3D environments with dynamic elements remains a significant challenge. This study presents an Enhanced Advanced Multi-Objective Path Planning (EAMOPP) model designed to address these challenges by improving feasibility, collision avoidance, and path smoothness while maintaining computational efficiency. The proposed enhancement introduces a hybrid sampling strategy that combines random sampling with gradient-based adjustments and a refined cost function that prioritizes obstacle avoidance and path smoothness while balancing path length and energy efficiency. The EAMOPP was evaluated in a series of experiments involving dynamic environments with high obstacle density and compared against baseline algorithms, including A*, RRT*, Artificial Potential Field (APF), Particle Swarm Optimization (PSO), and Genetic Algorithm (GA). Results demonstrate that the EAMOPP achieves a feasibility score of 0.9800, eliminates collision violations, and generates highly smooth paths with an average smoothness score of 9.3456. These improvements come with an efficient average execution time of 6.6410 seconds, outperforming both traditional and heuristic-based methods. Visual analyses further illustrate the model's ability to navigate effectively through dynamic obstacle configurations, ensuring reliable UAV operation. Future research will explore optimizations to further enhance the model's applicability in real-world UAV missions.

Abstract

Geometry has emerged as a challenging topic in elementary mathematics due to its demand for solid cognitive capacities and spatial ability. Students struggle to understand geometry topics, particularly in solid space and three-dimensional objects. The students need help comprehending various three-dimensional shapes and understanding the formulas and definitions related to geometry. This paper aims to design and develop an application for learning solid space topics. The application provides explanations of solid space concepts, interactive exercises, and assessments to enhance students' understanding. The development process follows the ADDIE method, which includes Analysis, Design, Development, Implementation, and Evaluation. The application was evaluated by a mathematics teacher. We also conduct black-box testing. The result shows that all the functionality was valid and the application can be used by students. Future research will focus on implementing the application in actual mathematic classes and evaluating the impact on student learning.
