Implementasi Otomatisasi Penyiraman Tanaman Cabai Menggunakan Arduino Uno R3 dan RTC DS1302 di Desa Waringinkurung

Abstract

Watering plants is a maintenance task that requires regularity; however, manual execution can be hindered by time constraints and scheduling inconsistencies. This study aims to implement an automated chili plant watering system using an Arduino Uno R3 and a DS1302 Real-Time Clock (RTC) in Waringinkurung Village, Cikeusal District, Serang Regency, Banten. The system is designed using an Arduino Uno R3 as the main controller, a DS1302 RTC for timekeeping, a 5V relay for pump control, a push-button for manual control, and a 125W water pump to distribute water from a storage tank to the plants via a piping network. The research employs a design-and-build methodology, encompassing hardware design, software design, implementation, and system testing. The system features three automatic watering schedules—07:05, 11:42, and 15:31—with a 10-minute duration for each. Testing covered RTC time accuracy, schedule adherence, pump operation duration, manual mode functionality, and water distribution. Test results indicate that the DS1302 RTC had an average time deviation of 0.6 seconds, while watering duration tests yielded an average error of 0.27%. These results demonstrate that the system successfully performs automated watering based on the schedule and supports manual operation as designed.
