Abstract

Currently, soil moisture monitoring is only done manually, which is less accurate, even though sometimes we need a soil moisture monitoring tool to determine the soil water content in plants. This research uses a Soil Moisture sensor to measure soil moisture and the NodeMCU ESP8266 microcontroller as the main controller. The system is designed to provide accurate and efficient soil moisture monitoring through the Internet of Things (IoT). The integration of Blynk as a monitoring application offers easy access to real-time soil moisture data via mobile devices. This system is designed to help users monitor soil moisture in real-time using NodeMCU as the main platform and Blynk for user interaction. Through this system, it is expected that users can avoid the risk of water shortages by knowing the soil water content in real-time. Based on testing, this soil moisture monitoring product has a success rate of 88.2% for soil moisture accuracy and an average user satisfaction rate of 60%.

Abstract

Teaching aids are learning media that can make it easier for students to understand material concepts. So far, the media used in learning is limited, especially in energy. This study aimed to determine how much influence the Solar Cell Teaching Kit has on students' learning outcomes on energy concepts. The method used in the study was an experimental class with a pretest-posttest control group design. The results of the test data analysis show that the average value of student learning outcomes in the experimental class reached 73.33, while in the control class, it was 62.5. This conclusion was obtained based on the hypothesis test results through the t-test on posttest data with a sample of 12 and a significance level of 5%. The result is a calculated t value = 5.613 while t table = 1.782. Because the calculated t value exceeds the t table, it can be concluded that the Solar Cell Teaching Kit significantly influences student learning outcomes on energy concepts.
