The purpose of this study saw the effects of ethanol extract of benalu tea (Scurrula oortiana) modulation of antibody titers of infected broilers gumboro (infectious like HIV). This research using 40 one-day-old broiler chickens (DOC). Broiler chicken experiment was obtained from livestock breeding. The cage was used multiple systems Cages, each unit consisting of one head .. The extract of Benalu tea (Scurrula oortiana) was processed by reflux extraction method with ethanol solvent. The dose regimented was used 10 mg/kg body werght insert to oral administrated start in 7 days until 35 days, and given gumboro virus infection at 20 days by oral administrated at dose EID50 107. Research treatment was used as follows; Group A, given the extract of benalu tea (Scurrula oortiana) without infected gumboro virus; Group B, without a given extract benalu teh (Scurrula oortiana) and without infected gumboro virus; Group C, given the extract of benalu teh (ScurruJa oortiana) and infected with gumboro virus; Group D, without any extract benalu teh (ScurruJa oortiana) and given infected with gumboro virus. Antibody was examined by ELISA method. The results prove that administration of benalu teh (Scurrula oortiana) in broilers infected with gumboro virus (like HIV) provide a significant impact especially in relation to an average of antibody titer (p <0.05). Therefore, the ethanol extract benalu teh (Scurrula oorliana) can be
considered as an antiviral against gumboro infections (like HIV) as well as improve the immune system
