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
