Rancang Bangun Charging Station pada Halte Bus UMA berbasis Panel Surya Sistem Off Grid

Abstract

Penelitian ini merancang dan menguji stasiun pengisian daya berbasis panel surya 100 Wp dengan sistem off-grid di halte bus UMA untuk menyediakan akses pengisian bagi pengguna transportasi umum dan mengurangi ketergantungan pada listrik konvensional. Sistem ini mencakup rancangan mekanik dan elektrikal serta diuji untuk mengisi perangkat seperti smartphone. Hasil pengujian menunjukkan kecepatan pengisian stabil pada 33,33% atau 1666,67 mAh per jam hingga 90% kapasitas, kemudian melambat untuk mencegah overcharging. Efisiensi optimal tercapai dalam 2,5 jam pertama, dengan waktu pengisian penuh sekitar 3 jam. Rancang bangun ini menunjukkan pengelolaan daya yang baik dan berkontribusi pada layanan transportasi publik ramah lingkungan. This study designed and tested a 100 Wp solar panel-based charging station with an off-grid system at the UMA bus stop to provide charging access for public transportation users and reduce dependence on conventional electricity. The system includes mechanical and electrical designs and was tested to charge devices such as smartphones. The test results showed a stable charging speed of 33.33% or 1666.67 mAh per hour up to 90% capacity, then slowed down to prevent overcharging. Optimal efficiency was achieved in the first 2.5 hours, with a full charge time of approximately 3 hours. This design demonstrates good power management and contributes to environmentally friendly public transportation services.
