| dc.description.abstract | TOMMI PERSADA SEMBIRING: The effect of rotary mechanical coffe roasting
temperature on the quality of Arabica coffee, supervised by ACHWIL PUTRA
MUNIR and SUMONO.
On mechanical equipment coffee roasters, roasting temperature needs to
be considered. The temperature determines the quality of the roasting product.
This study was testing the temperature at various levels coffee roasters rotary tool
on the yield and quality of coffee. The study was conducted at the Laboratory of
Agricultural Engineering USU College of Agriculture in January to April 2013 by
using a non-factorial completely randomized design at 700
C, 750
C, 800
C, 850
C,
900
C. Parameters measured were yield, processing capacity and water content.
The results showed that the test temperature had highly significant effect on yield,
had highly significant to the processing capacity, and had no significant effect ton
the water content.
The best treatment of this research was the treatment T3 (800
C) which
produced 81.2% yield, processing capacity of 3,252 kg / hour, and the water
content of 5.948% | en_US |
