Abstrak

Orchid cultivation requires proper watering management because insufficient or excessive water can reduce plant quality and damage the growing medium. Manual watering is also less effective when plant owners cannot monitor soil moisture regularly. This study evaluates an Internet of Things-based automatic watering system using NodeMCU ESP8266, a capacitive soil moisture sensor, a relay module, a water pump, a 16x2 LCD, and Telegram notification. The research was conducted using a prototype method consisting of communication, quick planning, quick design, prototype construction, and user feedback. System testing was performed on the sensor, pump, LCD, relay, Telegram notification, and the integrated device. The results show that the system can automatically activate the pump when soil moisture is in the dry range of 0%-30% and deactivate the pump when the moisture is above 31%. Telegram notification testing produced a 100% successful delivery rate with an average delivery time of 30 seconds. The pump operated at an average voltage of 11.95 V and an average current of 0.95 A. These results indicate that the proposed system can support orchid watering automation and remote monitoring for small-scale ornamental plant cultivation.
