Water level control system in rice fields with the SRI (System Rice Intenfification) model based on IoT (Internet of Things)

Abstract

The SRI (System Rice Intensification) model of rice cultivation has been able to produce higher productivity than conventional system. With the SRI model, land productivity can reach 21 tonnes per ha, 4 times the national productivity of 5.3 tonnes per ha. The water controller is one of the requirements in this model, and this one is become a major obstacle to be applied in the field at the farmer level. The water controller that is able to provide the highest land productivity is in the initial phase. in this phase the water level is 0-2 cm above the soil surface, in the vegetative and generative phases 3 cm below the soil surface, during the grain filling phase 7 cm below the soil surface, and it is dried. (irrigation is stopped) during the ripening phase or 10 days before harvest. In this research we develops a water control system using Internet of things technology so that all water level data can be recorded precisely and the process of adding water to the SRI rice field model can be done through an automation mechanism which controls the recorded process of control as well. The results of this study indicate the level of precision of the measuring tool works well and the automation system works as desired. The recorded measurement data can also be part of the analysis for the growth of the rice plant
