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.

Abstract

The reduction in agricultural land due to being converted into housing and urban areas means that the amount of food production is decreasing. Based on the problems above, the author offers an innovation to overcome the problem of food security through "Smart Farming". This innovation can be implemented by the community using the concept of integrated agriculture with fisheries which is easy to apply on minimal land which has not been utilized properly. However, currently There is currently no system that can monitor the pH and PPM levels of water automatically and easily. This has an impact on the poor quality of hydroponic plant production so that it cannot be sold to consumers and causes losses for this business Internet of Things (IoT) and website, this smart farming innovation was developed as a system for monitoring the condition of pH and PPM levels of water in hydroponic planting media. The development of a website-based pH and PPM monitoring system offers an innovative approach in utilizing technology to overcome the challenges of monitoring water quality effectively. By utilizing the advantages of information technology and the internet, this system can become an important solution in supporting efforts to protect the environment and sustain water resources in the future.

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
