Abstract

Soil moisture is a crucial factor in agriculture that affects plant growth and crop productivity. In modern agricultural systems, accurate soil moisture monitoring is essential for optimizing water usage and enhancing the efficiency of automatic irrigation systems. This study aims to develop an Internet of Things (IoT)-based soil moisture monitoring system and evaluate the performance of three types of soil moisture sensors: Soil Moisture FC-28, Capacitive Soil Moisture Sensor, and Soil Moisture Hygrometer Module Sensor. The evaluation compares the accuracy and effectiveness of each sensor in measuring soil moisture. The research methodology involves measuring soil moisture in ten different soil samples using the three sensors simultaneously. The system is based on the ESP32 microcontroller, where data from the sensors are processed and displayed on an LCD Liquid Crystal I2C 20x4. Data analysis is conducted using the one-way ANOVA statistical method to determine whether there are significant differences among the measurement results of the three sensors.The results indicate that each sensor exhibits different measurement characteristics based on its working principle. The Soil Moisture FC-28 sensor, which operates on resistance, shows high sensitivity to changes in soil moisture but is susceptible to corrosion. The Capacitive Soil Moisture Sensor is more durable as it does not have direct contact with the soil, yet it requires more precise calibration. Meanwhile, the Soil Moisture Hygrometer Module Sensor provides more stable results under various environmental conditions. The one-way ANOVA analysis reveals no significant differences in the measurement results among the three sensors.

Abstract

Keterbatasan sarana praktikum di sekolah dasar sering menjadi kendala dalam menyampaikan materi sains secara menarik dan aplikatif, terutama pada konsep rangkaian listrik. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pemahaman konsep rangkaian listrik seri dan paralel pada siswa kelas VI SD Negeri 010 Bukit Bestari melalui pembelajaran interaktif berbasis simulasi dan praktikum langsung. Metode pelaksanaan meliputi penyampaian materi pengantar, demonstrasi simulasi menggunakan PhET Circuit Construction Kit DC, serta kegiatan praktikum merangkai rangkaian listrik sederhana yang dipandu dengan Lembar Kerja Siswa (LKS). Siswa dilibatkan secara aktif dalam mengamati, merangkai, dan mendiskusikan hasil percobaan sehingga proses belajar menjadi lebih kontekstual dan bermakna. Evaluasi kegiatan dilakukan menggunakan angket respon yang diberikan kepada siswa dan guru untuk menilai efektivitas pelaksanaan, kebermanfaatan materi, serta pengalaman belajar yang diperoleh. Hasil angket siswa menunjukkan nilai rata-rata sebesar 3,7 yang berada pada kategori sangat baik, sedangkan penilaian dari guru berada pada kategori baik hingga sangat baik. Temuan ini menunjukkan bahwa kegiatan PKM mampu meningkatkan keterlibatan siswa, pemahaman konsep, serta minat terhadap pembelajaran sains. Dengan demikian, kegiatan ini efektif sebagai alternatif pembelajaran berbasis praktikum di sekolah dasar dan memiliki potensi untuk diterapkan secara berkelanjutan.

Abstract

Sea Surface Temperature (SST) is an important parameter in oceanographic studies because it influences climate dynamics, ocean circulation, and marine ecosystems. Continuous monitoring of SST in open sea areas requires a reliable system capable of operating autonomously. This study develops a solar-powered ocean buoy designed to measure sea surface temperature while simultaneously evaluating the performance of a solar panel as the main energy source. The system uses a DS18B20 sensor to measure SST and an INA219 sensor to monitor the voltage, current, and power of the solar panel, while an ESP32 microcontroller functions as the central data processing unit. The results show that sea surface temperature tends to remain relatively stable with small daily variations, whereas the temperature and performance of the solar panel exhibit larger fluctuations due to direct exposure to solar radiation and changing weather conditions. Solar panel performance also shows significant variations in current and power depending on the intensity of sunlight. To analyze the influence of SST variations on solar panel performance, a statistical analysis using Analysis of Variance (ANOVA) was conducted. The ANOVA results, based on the calculated F-value and the significance value (p-value) at a confidence level of α = 0.05, indicate that SST variations have a significant effect on solar panel performance, demonstrating that the proposed solar-powered buoy system can operate autonomously and has potential for long-term SST monitoring in offshore areas.
