Rancang Bangun Model Monitoring Underground Tank SPBU Menggunakan Gelombang Ultrasonik Berbasis Mikrokontroler

摘要

Intisari— Sistem monitoring tangki pendam penyediaan BBM di SPBU saat ini banyak digunakan. Dalam hal ini dapat kendala yang sering dihadapi karena belum menggunakan sistem otomatis. Monitoring pengukuran level ketinggian BBM didalam tangki pendam menggunakan garis ukur. Pada Tugas Akhir ini telah dirancang model monitoring tangki pendam SPBU menggunakan aplikasi gelombang ultrasonik dengan cara time of light. Model monitoring ini untuk membuat suatu sistem peringatan dini apabila BBM didalam tangki pendam sudah mulai habis. Sistem alat terdiri dari transmiter, receiver ultrasonik yang berbasis mikrokontroler ATMega8535. Transmiter dan receiver diarahkan ke tangki pendam. Dimana jarak berbanding lurus dengan waktu pemancaran transmiter sampai diterima kembali oleh receiver, kemudian diproses menggunakan mikrokontroler ATMega8535 sebagai pengendali utama, dan LCD sebagai penampil keadaan BBM yang ada didalam tangki pendam. Kata kunci— Ultrasonik, Mikrokontroler ATmega8535, Tangki Pendam, LCD. ? Underground tank monitoring system supplying fuel at the pump is currently widely used. In this case can the obstacles often faced due to not using the automated system. Monitoring fuel level measurement in tanks buried height using a measuring line. In this final project has been designed model of monitoring a buried tank filling station using ultrasonic waves by means of the application time of light. This monitoring model to create an early warning system when the fuel in the tank buried already running out. The system consists of a transmitter apparatus, ultrasonic receiver microcontroller based ATMega8535. The transmitter and receiver are directed to a buried tank. Where the distance is proportional to time broadcasting transmitter until it is received back by the receiver, and then processed using a microcontroller ATMega8535 as the main controller, and LCD as the state of the viewer is inside the fuel underground tank. Keywords— Ultrasonic, Microcontroler ATmega8535, Underground Tank, LCD.
