@article{Jourdan Aulia Hafidh_2021, title={simulation SIMULATION OF RIVER WATER LEVEL MONITORING SYSTEM IN LODAGUNG USING HC-SR04 SENSOR WITH WEB SERVICE REST API}, volume={7}, url={http://jip.polinema.ac.id/ojs3/index.php/jip/article/view/480}, DOI={10.33795/jip.v7i4.480}, abstractNote={<p><em>The measuring line or commonly called pascal around the floodgates is very important for the floodgate supervisor. The measuring line is very large when river water overflows due to rain. However, because it still has a danger effect such as when the floodgate supervisor sees a measuring line when it rains, the risk in the work is even more dangerous. The authors of this study have developed an automatic altitude measurement simulation in which this automatic water level gauge is useful and can be applied properly in a field where there are no pascals or measuring lines around the floodgates.The measurement results are received directly by the web page and stored in the database. In this automatic water level measurement simulation there are 2 conditions namely rain and drought where in 2 circumstances have been taken from location data and have 3 phases, dry water, normal water and overflow water.In 2 rainy and dry conditions have different height limits</em></p&gt;}, number={4}, journal={Jurnal Informatika Polinema}, author={Jourdan Aulia Hafidh}, year={2021}, month={Aug.}, pages={33-42} }
