Perancangan Sistem Pengaturan Suhu pada Mesin Sangrai Kopi Berbasis Logika Fuzzy
Abstract: One of commodity in
Bondowoso district is a coffee. There are two coffee flavor i.e. arabica and
robusta. The quality of coffee is depending on the roasting temperature of
coffee. At constant temperature, it require long roasting time around 1,5 to 2
hours. Because of that, automatically temperature control system was needed to
control the roasting temperature to make the roasting time faster and more
efficient by using fuzzy logic method. Sugeno method was used in this study by
inputing error temperature and ∆ error temperature. The results show that
temperature censor has 1.95% error against actual temperature of termometer.
The fuzzy logic controls the actuator movement to regulate the valve of LPG
that is fuel of furnace roaster. By using fuzzy logic, roasting time of arabica
coffee and robusta coffee are 36,9 minutes and 30,216 minutes, respectively.
