Abstract

Electric bicycles are bicycles that are battery powered and driven by a motor. Electric bicycles can utilize more than one energy source, namely generator energy and solar energy to supply the battery, which is called hybrid energy. Battery charging is limited when it is full to prevent overcharging. Battery charging can be done using several methods, one of which is the Constant Voltage (CV) method. The stage for synchronizing hybrid energy sources is to condition the voltage of both hybrid sources so that the same value is achieved. Conditioning over charge uses an auto cut-off circuit which can cut off the source current if the battery is full, indicated by a Light Emitting Diode (LED). Research shows that battery charging by relying on a boost converter to synchronize the two sources can work very well. The boost converter voltage does not accumulate because both boost converters are installed in parallel. The auto cut-off circuit can prevent overcharging the battery by utilizing a zener diode and relay.

Abstract

Aliran sungai sangat penting bagi sektor pertanian dan perkebunan di Desa Bentunai, digunakan untuk sistem irigasi yang meningkatkan hasil panen. Oleh karena itu, diperlukan sistem monitoring ketinggian air sungai menggunakan PLTS sebagai sumber energi, ESP32 sebagai mikrokontroler, dan sensor ultrasonik untuk mendapatkan data ketinggian air, serta IoT untuk akses jarak jauh. Energi untuk sistem ini diperoleh dari panel surya yang mengubah sinar matahari menjadi listrik dan menyimpan energi di baterai, memungkinkan operasi terus-menerus bahkan di malam hari atau cuaca buruk. ESP32 mengelola sensor yang membaca ketinggian air dan mengirimkan data real-time melalui Wi-Fi ke aplikasi yang digunakan. Hasil dari pengujian menunjukkan persen error pembacaan sensor adalah 0,25% sedangkan hasil pembacaaan IOT dengan thingspeak mengalami delay 23 detik. Hasil pembacaan sensor dengan IOT menunjukkan hasil pembaacaan yang stabil. Hasil pemantauan ketinggian air menunjukkan puncaknya dibulan januari. Dengan sistem ini dapat membantu pemantauan pasang surut air harian.
