Abstract
Dalam dunia industri fenomena perpindahan panas
dimanfaatkan untuk keperluan proses dengan menggunakan suatu
alat yang disebut penukar panas (heat exchanger). Salah satu tipe
heat exchanger di industri adalah shell and tube heat exchanger.
Perancangan sistem pengendalian temperatur tube pada mini plant
heat exchanger tipe shell dan tube ini adalah sistem yang
mengendalikan temperatur pada output tube heat exchanger,
sensor yang digunakan untuk mengukur variabel temperatur
adalah sensor thermocouple tipe K dengan rangkaian
pengkondisian sinyal serta amplifier menggunakan ic AD595AQ
dan ic LM358. Pengendalian temperatur dikontrol dengan
mikrokontroler ATmega8535 untuk menghasilkan output dengan
set point 45ºC. Ketika set point tercapai maka solenoid valve yang
ada pada tube akan terbuka. Dari data pengujian sensor
didapatkan rata-rata koreksi ± -0,91615385 ºC dan error ±
0,0153ºC. Berdasarkan pengujian alat pada sistem pengendalian
temperatur tube didapatkan respon time yang baik untuk
mencapai stedy state dengan maksimum overshoot 1
oC dan nilai
error steady state sebesar 0,1951 dengan settling time ± 116
menit dengan efisiensi perpindahan panasnya adalah 0,156 yang
dapat dikatakan perpindahan panasnya baik karena nilai yang
diperoleh < 1.

In industrial world, heat transfer phenomena utilized for the
process by using a device called heat exchanger. One type of heat
exchanger in the industry is shell and tube heat exchanger. The
design of tube temperature control system on mini-plant heat
exchanger shell and tube type is system that controls the
temperature of tube output heat exchangers, sensors are used to
measure the temperature variable is the sensor thermocouple type
K with a series of signal conditioning and amplifier using ic
AD595AQ and ic LM358 , Temperature control is controlled by a
microcontroller ATmega8535 to produce output with a set point
45ºC. When the set point is reached, the solenoid valve that on the
tube opens. Sensor test data obtained from the average correction
± -0.91615385 ° C and ± 0,0153ºC error. Based on the test tool
on the temperature control system of tube obtained a good
response time to reach stedy state with 1 oC maximum overshoot
and error steady state value of 0.1951 with a settling time ± 116
minutes with heat transfer efficiency is 0.156 which can be said to
be good because of heat transfer earned value <1.
