Using the Internet of Things to optimize the Design of a Floodgate for irrigation in Malang Regency, Poncokusumo Village in Indonesia

Agriculture is a very important practice that requires irrigation. However, since water is not always available in a stable manner, village water reservoirs are needed. Furthermore, irrigation is used to collect village water, which frequently overflows and wastes if not controlled. Based on the Internet of Things, the performance of the sprinkler irrigation water extractor is one of the innovations in water regulation that can be controlled remotely to monitor the level of water in the reservoir and thereby meet the water needs of the plants. The method used in this study is the observational approach, with direct research on the optimized design of floodgates in reservoirs and rice fields in Poncokusumo Village. Furthermore, this study requires hydrology, river discharge, soil, plant species, topography, climatological data, and a reservoir. Meanwhile, the irrigation water system was remotely controlled using the Blynk app. Based on the results of the calculations and observations, it is known that the floodgates will be opened and closed within specific hours each month based on the specifications of the village irrigation flow. Furthermore, the current discharge required by the village’s plants is 0.01375 m3/second, and the first sensor measurement is a height of 50 cm from the bottom of the reservoir. If the reservoir’s water level has already reached this level, a water notification will appear to alert you that the reservoir is nearly empty and needs to be refilled. While the second sensor installed at a height of 370 cm can detect when the water level is approaching its maximum. Consequently, the data will be displayed on the Blynk app for Android.
