Abstract
Fluida merupakan zat yang mempunyai partikel mudah bergerak dan berubah bentuk tanpa pemisahan massa. Hukum fisika yang berhubungan dengan fluida adalah hukum hidrostatik dimana tekanan hidrostatik suatu tabung tertutup akan berpengaruh terhadap level air. Untuk mengukur level air secara otomatis dibutuhkannya sistem pengendalian level. Pada tangki 2 komponen yang digunakan yaitu sensor ultrasonik HC-SR04, aktuator pompa air, dan mikrokontroler ATMega1284p. Ada dua hasil yang didapat pada sistem pengendalian level tangki 2. Pertama yaitu pengisian tangki 1 lebih cepat dibandingkan dengan tangki 2 karena menggunakan aktuator MOV (Motor Operated Valve) dan alat ukur orifice plate. Kedua yaitu diperoleh hasil nilai respon sistem. Pada setpoint 25 cm didapatkan hasil dengan nilai error steady state sebesar 0,2%, maksimum overshoot (Mp) sebesar 3,7%, dan settling time sebesar 41 detik, dan pada setpoint 26 cm didapatkan hasil dengan nilai error steady state sebesar 0,1%, maksimum overshoot (Mp) sebesar 7,1%, dan settling time sebesar 52 detik.

A fluid is a substance that has a particles easy to move and change shape without separation of the masses. The laws of physics that deals with fluid is hydrostatic law where hydrostatic pressure in a closed tank will affect the height of the water. To measure water height automatically can be needed a level control system. The components which used in tank 2 are ultrasonic sensors HC-SR04, pump actuator and microcontroller of the ATMega1284p. There are two result which can be obtained in level control system tank 2. The first is tank 1 fill more faster than tank 2 because tank 1 use MOV (Motor Operated Valve) actuator and orifice plate measure. The second is obtained the result of response system. In 25 cm of setpoint are obtained error steady state 0,2%, maximum overshoot (Mp) 3,7% and settling time 41 second, and in 26 cm of setpoint are obtained error steady state 0,1%, maximum overshoot (Mp) 7,1% and settling time 52 second.
