Abstract

ITS memiliki sungai kecil yang mengalir kesungai besar menuju laut. Sungai di jalan raya ITS menggunakan pintu air sebagai pengatur jalan keluar air sungai di ITS, saat hujan turun sungai di ITS menjadi tinggi dan lama-kelamaan meluber ke jalanan. Alat deteksi dini bahaya banjir bekerja dengan cara mendeteksi ketinggian air sungai, alat ini menggunakan rangkaian ultrasonik yang terdiri dari rangkaian transmitter (Rangkaian osilator CMOS, rangkaian Switch dan rangkaian inverting) dan receiver (Penguat sinyal tegangan analog, komparator tegangan , Pass Filter . Alat ini menggunakan teori Time-Of-Flight, hasil dari pengukuran akan mengaktifkan motor servo dan pompa listrik. Hasil ketinggian air yang diperoleh sensor ultrasonik menjadi parameter untuk membuka pintu air dan mengaktifkan pompa listrik. Pada hasil percobaan saat ketinggian air sungai berada 12 cm maka posisi pintu terbuka dan pompa ON. Sensor ultrasonik masih memiliki error 21,05% perlu menggunakan crystal 40Khz untuk hasil pengukuran yang lebih ====================================================================================================== ITS has a small river flowing to large river towards the sea. Rriver highway ITS used sluice as a regulator of exit ITS river water, when it rains the river raise high and eventually spills into the street. Flood hazard early detection tool works by detecting the water level of the river, this tool uses series of ultrasonic transmitter consisting of a series (CMOS oscillator circuit, Switch Circuit and inverting) and receiver (Analog voltage sinyal ampilfier , comparator Voltage, Pass Filters . This tool uses the theory of Time of Flight, the results of the measurement will be in actuators with servo motors and electric pumps. The results obtained water level ultrasonic sensor becomes a parameter to open the floodgates and activate the electric pump. In the experimental results when the river water level was 12 cm, then the position of the open door 10 cm and the pump ON. Ultrasonic sensors still have a 21,05% error need to use 40Khz crystal for measurement results more
