Abstract
During the rainy season, inundation often occurs in the rice fields which causes crop failure. Several factors that cause this phenomenon are high rainfall intensity and non optimal absorption of ground water. These puddles are difficult to recede and can cause excess inundation. The opening of the irrigation gate also resulted in the buildup of puddles, submerging the rice fields. Therefore, it is necessary to plan an irrigation system that is accommodated by a ground tank which acts as a useful water collector during the dry season. The purpose of this study was to determine the amount of runoff that occurred and overcome the problem of excess water in the rice fields during the rainy season and water shortages during the dry season. This irrigation system uses pump sensors placed in rice field plots, where the pump sensor works based on the volume of rice field water. The pump sensor will detect when the volume of water in the fields has exceeded capacity, then the pump will drain the excess water to the ground tank. To avoid water shortages in the fields during the dry season, the water stored in the ground tanks is channeled back into the fields. Thus, the existence of this irrigation network system can overcome inundation in rice fields in a shorter time without having to wait for the water to recede while optimizing the use of water as a reserve in the dry season.
