Abstract

Salah satu kegiatan wajib bagi pendidik di Perguruan Tinggi dalam melaksanakan Tri Dharma Perguruan Tinggi adalah melakukan pengabdian kepada masyarakat. Pada kesempatan ini telah dilakukan Workshop Pemanfaatan Sel Surya sebagai Sumber Energi Listrik pada Siswa SDN Bugangan 03 Semarang sebagai salah satu bentuk pengabdian kepada masyarakat. Ditengah isu tentang semakin menipisnya ketersediaan energi fosil, kemunculan sumber energi terbarukan (EBT) menjadi penting. Pengenalan EBT perlu dilakukan bahkan ditingkat Sekolah Dasar. Sel surya merupakan sumber EBT yang banyak dimanfaatkan terutama dalam penerangan jalan, dan beberapa kebutuhan listrik di wilayah yang kaya akan sumber energi Matahari. Oleh sebab itu pada kegiatan pengabdian kepada masyarakat kali ini dilakukan workshop pemanfaatan sel surya dengan tujuan agar siswa SDN Bugangan 03 dapat mengenal secara langsung apa itu sel surya dan pemanfaatannya dalam menghasilkan energi listrik.

Abstract

Koi fish farming requires careful monitoring of water temperature and pH to prevent adverse impacts on the fish. This study presents a prototype IoT-based autofeeder that integrates real-time water quality monitoring and automatic feeding, controllable via both an Android application and local device buttons. The system allows users to configure feeding schedules, feed throw levels, and durations, as well as set pH thresholds. When the pH exceeds the safe range, the system automatically stops feeding and sends notifications, enabling the user to inspect and maintain pond water quality. The findings demonstrate that the dispensing level significantly influences the feed-throwing distance; higher dispensing levels result in longer distances. Small-sized feed (S) consistently produced the highest output, followed by medium-sized (M) and large-sized (L). Increasing the feeding duration enhanced the weight of the released feed. Additionally, the average delay in sensor data transmission to the database was recorded at 5.48 seconds. The data loss rate during the testing period was 1.72%, which is considered acceptable and does not adversely affect system operations. The data transmission system demonstrated good and stable performance with relatively low data loss.
