Abstract

A power analysis and performance study of a vehicle safety system combines vehicle contactor control, battery voltage monitoring, and an automatic disconnect feature to maintain power stability. Quantitative system performance measurements using statistical and probability approaches included connection reliability, voltage drop patterns, current distribution, and the relationship between operating time and power consumption. A total of 300 observation data sets were collected from a controlled testing process. The results show that battery voltage drop follows a negative linear trend with a correlation coefficient of -0.54, indicating a moderate relationship between load duration and voltage degradation. Analysis of relay response probabilities and WiFi connectivity showed a 96.3% success rate and a 3.7% probability of connection failure under standard network conditions. The distribution of errors in voltage measurements tended to follow a log-normal pattern based on the Kolmogorov–Smirnov test. The findings confirm that the safety control system performs stably in most test scenarios, but requires specific optimization when peak currents occur

Abstract

The perception of complexity and a lack of real-world relevance often hinder elementary school students' interest in robotics. This study aimed to evaluate the effectiveness of creative project-based learning in building a strong foundation in robotics and enhancing student engagement at SD Margorejo 1 Surabaya. By integrating design thinking principles and project-based learning, this approach sought to create authentic and meaningful learning experiences. Employing a qualitative case study methodology with a participatory action research design, fifth-grade students were involved in a series of robotics projects designed to address real-world problems in their local environment. Data were collected through participant observation, semi-structured interviews, and project artifact analysis. The findings revealed that creative project-based learning significantly increased students' interest in robotics. Students not only grasped fundamental robotics concepts but also developed critical thinking, creativity, and collaboration skills. Moreover, this approach effectively strengthened students' understanding of STEM (Science, Technology, Engineering, and Mathematics) concepts and fostered awareness of robotics' relevance in daily life. This study concludes that creative project-based learning is an effective strategy for building a strong robotics foundation and cultivating student interest at the elementary school level.

Abstract

This research aims to analyze the effectiveness of project-based learning in increasing technological literacy in elementary school students. Activities were carried out for three months for 25 class V students at SDN Margorejo 1 Surabaya. The material includes an introduction to basic electronic components, sensors, and simple robot assembly such as line follower and obstacle avoidance. The research used a mixed-method approach with a one-group pretest-posttest design. The main instruments are a technology literacy test and a participatory observation sheet. The results showed an increase in the average score from 48.2 (pretest) to 78.4 (posttest), with the t-test results showing significance (p < 0.05). Qualitatively, students show high enthusiasm, increased curiosity, as well as collaborative and problem-solving abilities. These results indicate that robotics project-based learning is effective in increasing the technological literacy of elementary school-aged children and is worthy of being integrated into basic STEM learning.
