MONITORING KELEMBABAN DAN PENYIRAMAN OTOMATIS TANAMAN BERBASIS IOT DI P4S ALAM AGRO BATU MELALUI WEBSITE

The Center for Agricultural and Rural Self-Reliance Training (P4S) Alam Agro
Batu is the research location focused on the development of a soil moisture
monitoring and automatic watering system based on IoT (Internet of Things). This
system is designed to address the issues of manual soil moisture management, which
often leads to suboptimal plant growth, especially for strawberry and tomato plants.
The system prototype consists of NodeMCU ESP8266, soil moisture sensor
(Capacitive Soil Moisture Sensor), relay, and water pump, integrated with
a ReactJS and Firebase-based website platform for real-time monitoring and
control. The research method used is R&D (Research and Development) with an
IoT-based system development approach. The system is capable of automatically
reading soil moisture data and activating watering when the soil moisture falls into
the dry category, which is 60-70% for strawberries and 60-80% for tomatoes.
System testing was conducted over 3 days for strawberry plants and 3 days for
tomato plants using the ASM (American Standard Method) to validate sensor
accuracy. The test results show that the system is able to maintain soil moisture
within the optimal range with a high level of accuracy. The developed website
allows farmers to monitor soil moisture data in real-time graphs, control watering
manually or automatically, and select the appropriate plant type. The
implementation results demonstrate that this system can be an innovative solution
to improve water management optimization and support better plant growth
