Abstract

The implementation of 25 kWp On-Grid Rooftop Solar Power Plant at SMK Negeri 3 Kupang is expected to provide a solution to the problem of dependence on conventional energy and reduce school operational costs. Therefore, it is important to conduct an analysis of the Rooftop Solar Power Plant system at SMK Negeri 3 Kupang, in order to optimize the use of renewable energy and reduce school electricity operational costs. This study aims to determine the performance of the Rooftop Solar Power Plant and the amount of savings that occur. The research method used is a descriptive method and direct measurement of the inverter, MDP, LVMDP to measure the current and voltage to obtain the output power of the Solar Power Plant, PLN and load. The results of the study showed that the operational performance of the Rooftop Solar Power Plant can be known through the efficiency of the Rooftop Solar Power Plant at SMK Negeri 3 Kupang which was obtained with a maximum value that occurred on Saturday of 86.96%. The measurement results showed that there were savings in power and bills at SMK Negeri 3 Kupang. With savings for 7 consecutive days of 84.87%; 91.60%; 35.98%; 58.73%; 57.74%; 25.15%; 84.04%.

Abstract

Pengabdian ini bertujuan memberdayakan Pemuda GMIT Lanud El-Tari di Penfui melalui pengembangan usaha hortikultura berkelanjutan. Permasalahan utama adalah kondisi tanah berbatuan, kurang subur, dan kendala pengairan yang menghambat inisiatif budidaya tanaman umur pendek. Solusi yang diterapkan adalah pembangunan instalasi irigasi tetes berbasis gravitasi, meliputi tower setinggi 2 meter, profiltank 1.200 liter, dan instalasi drip 150 micron untuk 100 titik tanam meliputi cabe 25 pot, tomat 25 pot, sawi 25 potn dan semangka 25 pot. Sistem ini terbukti sangat efisien, dengan total kebutuhan air harian 276 liter, yang dapat dilayani profiltank hingga 5 hari. Hasil panen awal (cabai 10 kg, tomat 12 kg, pitcay 20 kg) membuktikan potensi ekonomi dan digunakan sebagai Diakonia Karitatif. Namun, hasil semangka kurang maksimal (<3 kg) akibat kendala pemupukan dan seleksi buah. Kegiatan ini sukses menciptakan model budidaya efisien air dan mendorong manajemen kewirausahaan jemaat.

Abstract

This study aims to design and implement a smart kWh meter system based on ESP32 that is capable of monitoring and controlling electricity consumption in households with a connected power of 1300 VA. The developed system utilizes the ESP32 microcontroller as the main data processor, which is integrated with the PZEM-004T sensor to measure electrical parameters, including voltage, current, power, energy, and power factor. Measurement data is displayed in real-time through the Blynk application, while control and limitation of energy consumption are managed using a Telegram bot service. The system is equipped with a relay to automatically disconnect the load when energy consumption exceeds a predetermined limit. System testing is conducted by comparing the sensor measurement results against the PLN kWh meter as a reference tool. The test results indicate that the developed smart kWh meter system operates effectively and possesses an average current measurement accuracy of above 99% across various types of household loads. Additionally, the load control and notification system based on Telegram functions reliably in limiting electricity consumption. Therefore, this system can serve as an effective solution to assist household users in monitoring and controlling electricity consumption more efficiently.

Abstract

Indonesia memiliki potensi energi surya yang besar sehingga pemanfaatannya pada sistem Penerangan Jalan Umum (PJU) berbasis tenaga surya sangat prospektif, namun panel surya dengan posisi statis belum mampu menyerap energi secara optimal akibat perubahan sudut datang sinar matahari sepanjang hari. Penelitian ini bertujuan untuk menganalisis pengaruh penggunaan solar tracker single-axis terhadap daya keluaran panel surya pada sistem PJU. Metode yang digunakan adalah metode eksperimental dengan membandingkan kinerja panel surya statis pada sudut 45°, 90°, dan 135° dengan panel surya dinamis yang dilengkapi sistem solar tracker single-axis berbasis Arduino Uno. Parameter yang dianalisis meliputi tegangan, arus, daya keluaran, dan persentase penyerapan energi, dengan pengujian dilakukan dari pukul 06.00 hingga 17.00 pada interval 30 menit. Hasil penelitian menunjukkan bahwa panel surya dengan sistem pelacak menghasilkan daya keluaran yang lebih tinggi dibandingkan panel statis, dengan total daya keluaran panel dinamis mencapai 64,84 W, sedangkan panel statis menghasilkan daya antara 31,25 W hingga 40,06 W. Selain itu, tingkat penyerapan energi panel surya dinamis mencapai 87,51%, lebih tinggi dibandingkan panel surya statis yang berada pada kisaran 42,18%–54,06%. Hasil ini menunjukkan bahwa penerapan solar tracker single-axis efektif dalam meningkatkan daya keluaran dan efisiensi energi panel surya pada sistem PJU.
