Abstract
Pada sistem pengendalian temperature merupakan suatu
rancangan sistem yang mampu mengendalikan temperature pada
miniplant greenhouse hidroponik khususnya pada temperature
reservoir tangki larutan nutrisi. Plan pengendalian temperature
reservoir ini menggunakan DS18B20 sebagai sensor suhu,
microcontroller ATmega8535 sebagai controller, LCD berfungsi
untuk menampilkan data dan aktuator yaitu fan dan pendingin
berupa peltier. Cara kerja dari plan pengendalian ini yaitu sensor
akan mendeteksi perubahan suhu pada tangki larutan nutrisi
temperature reservoir yang kemudian diolah oleh microcontroller
sehingga perubahan suhu dapat ditampilkan melalui LCD. Error
pada tangki larutan nutrisi dilakukan pengendalian untuk nilai
temperature yang sesuai dengan menggunakan metode fuzzy,
kemudian ditentukan nilai set point atau nilai zero yang sesuai
yaitu 20-28°C. Pada hasil pengujian dapat terlihat bahwa nilai
temperature bergantung pada jam pengambilan, pada pukul 00.00
sampai 23.00 nilai tangki temperature reservoir setelah dikontrol
yaitu antara 26,1°C sampai 27,6°C, untuk perhitungan akurasi
sistem, didapatkan bahwa sistem pengendalian temperature
reservoir pada tangki larutan nutrisi mempunyai akurasi sebesar
99,4%

The temperature control system is a system than can control
the temperatur in miniplant of greenhouse hydroponic especially
in nutrient tank reservoir. The temperature control system used
are DS18B20 as a temperature sensor, microcontroller
ATmega8535, LCD as displayed of data, and the actuator that
uses by cooling fan and peltier. The work principle of the control
plant is beginning from temperature sensor. The sensor will
detect a temperature change in the nutrient temperature reservoir
tank which is then processed by a microcontroller so that changes
in temperature can be displayed on the LCD. In nutrient tank
should be controlled to the corresponding temperature values
using fuzzy method, then it determined the appropriate set point
or zero value of temperature is 20 - 28 ° C. In the test results the
temperature values depend on the time, at 00.00 till 23.00 the
value of temperature after reservoir tank controlled, the
temperature is between 26.1 ° C to 27.6 ° C, it was found in the
temperature control system at the reservoir nutrient solution tank
has an accuracy of 99,4%
