JONSION PURBA : test of Mechanical Coffee Pulper Equipment, supervised by SAIPUL BAHRI DAULAY and ACHWIL PUTRA MUNIR. Equipment test is one of agriculture processing. The research was aimed to test Arabica coffee wich is appropriate with Mechanical Coffee Pulper Equipment from 3 different origin places of coffee to equipment capacity, percentage of coffee damage, percentage of unpulped coffee, percentage of coffee bean in drain skin and percentage of skin in pipe bean. Conducted from September to October 2013 in Agriculture Engineering Laboratory. Agriculture Faculty, Sumatera Utara University, Medan, by using non-factorial completely randomized design (CRD). The parameters measured were equipment capacity, percentage of unpulped coffee, percentage of coffee damage, percentage of coffee bean in drain skin, and percentage of skin in pipe bean. The results showed equipment capacity of 119,80 kg/hr, 157,00 kg/hr and 160,86 kg/hr. percentage of unpulped coffee of 16,50%, 6,83% and 15,50% percentage of coffee damage of 5,30%,6,90% and 7,90% percentage of coffee bean in drain skin of 3,20%, 4,76%, and 4,96% percentage of skin in pipe bean of 2,93%, 2,50%, and 3,06%.
