Abstract

The issue in this research is that students struggle to move because they lack fundamental throwing and catching mobility skills. There are still many students who look stiff and need the teacher's assistance to move in accordance with the teacher's instructions, even though some students are less able to practice throwing and catching balls, even though some students can already do so. The purpose of this study was to determine the level of fundamental movement skills for throwing and catching a baseball in primary school. The sample of this research is class III MIS AL Qosimy Watu Galuh, totaling 25 people. Data collection techniques using a t-test: The P value obtained is less than 0.05, which is 0.00. In the catch test, the test statistic results show the P-value obtained is less than 0.05, which is 0.00, with an average value of 34.54. The results of the test statistic on the throwing and catching values show that the P-value obtained is less than 0.05, which is 0.00. So it can be concluded that the throwing value of the students is equal to 15 with an average value of 11.5. The results of the overall analysis show that the components of the throw, catch, and throw catch scores of each student are not the same as the expected target value.

Abstract

Robotic technology is a crucial pillar in modern civilization, especially in high-risk environments such as post-disaster evacuation scenarios. Hexapod legged robots are designed to navigate uneven terrains that are inaccessible to humans. Although hexapods offer superior mobility and flexibility, they face stability challenges when moving on inclined surfaces due to uneven load distribution, which can affect servo motor performance. To address this issue, this study implements a control system combining fuzzy logic and inverse kinematics to maintain body stability. An Inertial Measurement Unit (IMU) sensor is also integrated to detect the robot’s orientation angle in real-time, enabling adaptive posture correction. This research focuses on three main problems: first, how inverse kinematics can stabilize hexapod posture on sloped surfaces; second, how IMU sensors detect inclination and orientation; and third, how fuzzy logic control contributes to balance regulation. The methodology involves system design, experimental testing, and performance analysis based on the robot's body tilt measurements across various inclinations. The results show that the proposed system responds effectively to surface tilt, particularly in pitch angle correction and maintaining a neutral position. Inverse kinematics successfully calculates leg configurations to keep the body posture stable. The IMU sensor demonstrates high accuracy in angle detection, while fuzzy logic provides flexibility in decision-making for posture control. The integration of these three approaches proves effective in maintaining hexapod balance on inclined terrains, thus supporting their potential use in complex, unstable environments.

Abstract

This study presents the design and simulation of an on-grid photovoltaic (PV) solar power system for the training room at PT. Pupuk Iskandar Muda (PT. PIM), located in North Aceh, Indonesia. As part of Indonesia’s renewable energy goals, this research explores the potential of rooftop solar installations in supporting the country's energy transition. Using the PVSyst simulation software, the study assesses the technical and economic feasibility of deploying a solar power system tailored to the building’s electricity demands and solar radiation characteristics. The design incorporates monocrystalline and polycrystalline solar panels, and system configurations are optimized based on factors such as panel capacity, inverter specifications, and site-specific conditions. The results indicate that a 2 kWp system can generate up to 2.91 MWh annually, with a performance ratio (PR) of 81.15%, demonstrating the system’s feasibility for sustainable energy use. The findings contribute to understanding the practical applications of rooftop solar power in educational and industrial sectors, providing insights into the potential for broader adoption across similar contexts in Indonesia.
