Abstract

The development of automotive technology, especially in electric vehicles, is accelerating. Electric vehicles utilize batteries as the main power source, making batteries a very vital component. Batteries function to store energy, but can experience a discharge if used without recharging. Therefore, a battery charging system is needed to reduce the possibility of discharge. One charging method that can be applied is constant voltage, where the voltage is kept constant from the beginning to the end of the charging process. To keep the voltage constant, a rectifier circuit and buck converter are used. The rectifier circuit functions to convert alternating voltage (AC) into direct voltage (DC), while the buck converter reduces the direct voltage (DC) and maintains it constant with control to regulate the switching on the MOSFET. In this research, the system is designed with an input voltage of 220 V which produces a constant output of 12 V. Control using PID allows duty cycle settings to reduce the direct voltage (DC). In a hardware test using a VRLA battery load, the test results showed that after charging for 25 minutes, the battery voltage increased from 11.49 V to 11.65 V.

Abstract

Program pengabdian masyarakat ini dilatarbelakangi oleh rendahnya pemanfaatan potensi budidaya ikan lele sebagai sumber ekonomi warga Kampung Banyumas, Jl. Giri Rejo II, Kecamatan Karang Joang, Balikpapan Utara. Kegiatan ini bertujuan untuk meningkatkan kemandirian ekonomi masyarakat melalui pengolahan produk lele dan penerapan teknologi tepat guna. Bahan dan metode pelaksanaan meliputi sosialisasi kepada warga, pelatihan pengolahan produk berbahan dasar lele, penerapan alat pakan otomatis dan kolam terpal, serta pendampingan intensif selama proses budidaya dan produksi. Evaluasi dilakukan melalui observasi keterampilan, efektivitas alat, dan keterlibatan peserta. Hasil kegiatan menunjukkan peningkatan kemampuan warga dalam memproduksi olahan bernilai tambah seperti abon, nugget, dan lele beku, serta meningkatnya efisiensi budidaya melalui penggunaan alat pakan otomatis. Selain itu, warga menunjukkan antusiasme lebih tinggi dalam mengembangkan usaha rumahan dan memanfaatkan teknologi sederhana dalam kegiatan produksi. Secara sosial, kegiatan ini mendorong kolaborasi dan semangat gotong royong antarwarga. Program ini berhasil meningkatkan keterampilan, efisiensi budidaya, dan kemandirian ekonomi masyarakat.
