Abstract
Dalam dunia industri nyata, banyak kebutuhan proses yang tidak dapat diselesaikan dengan loop sederhana yang hanya mengandalkan sebuah mata rantai feedback. Contoh paling nyata adalah pengendalian suhu pada heat exchanger dalam proses Desalinasi. Pada judul tugas akhir ini dibahas mengenai bagaimana mengendalikan temperature outlet Heat Exchanger dengan manipulasi flow inlet Heat Exchanger yang dijaga temperaturnya pada titik 120 derajat Celsius. Komponen penunjang yang digunakan meliputi sensor Thermocouple Type K, sensor Water Flow, Aktuator berupa Ball Valve yang digerakkan oleh Motor Servo, mikrokontroler berupa ATMega1280, dan tampilan visual berupa LCD 16x4 untuk flow dan bukaan valve, dan HMI (Human Machine Interface) pada PC (Personal Computer) untuk temperature. Pada sistem pengendalian temperature – flow secara cascade control ini mempunyai nilai maximum overshoot (Mp) sebesar 4,83 %, Settling Time (Ts) selama 300 s, dan Error Steady State (Ess) sebesar 4,4 %.

In the real world of industry, many process needs can not be solved with simple loops that rely on a single feedback link. The most obvious example is the temperature control of the heat exchanger in the desalination process. In this Final Project title discussed about how to controlling temperature outlet Heat Exchanger with flow inlet Heat Exchanger manipulation which kept it temperature at a setpoint 120 Celsius degrees. The supporting components used include Thermocouple Type K sensor, Water Flow sensor, Actuator of Ball Valve driven by Motor Servo, microcontroller of ATMega1280, and visual display of 16x4 LCD for flow and valve opening, and HMI (Human Machine Interface) on PC (Personal Computer) for temperature. The temperature – flow cascade control system has a maximum overshoot (Mp) value of 4.83%, Settling Time (Ts) for 300 s, and Error Steady State (Ess) of 4.4%.
