Abstract

The research aims to install a smart agriculture system in paddy field management for real-time monitoring of nitrogen (N), phosphorus (P) potassium (K), and pH. After that, use the information to calculate the amount of fertilizer utilization and reduction of greenhouse gas emissions from the project's implementation. The results showed that data were collected through smart online monitoring for 1 month, it was found that nitrogen was 180-200 mg L^-1, phosphorus was 200-300 mg L^-1, potassium was 500-800 mg L^-1 and pH was 7.08-7.28. After that, planning for the amount of fertilizer utilization formulas 46-0-0 and 16-20-0 to control the ratio of N: P: K to be optimal for rice growth. As a result of the smart agriculture system for paddy field management, it was found that help to save costs by 50%, reduce fertilizer use by 50% without declining yields, and reduce greenhouse gas emissions from this project by 58 kg CO₂ eq. Moreover, the proper use of fertilizers can also reduce the accumulation of chemicals in the soil that will negatively affect soil microorganisms and cause soil depletion.
