UJI AKTIVITAS ANTIBAKTERI DARI EKSTRAK AIR DAN ETANOL BAWANG PUTIH (Allium sativum L.) TERHADAP BAKTERI GRAM NEGATIF DAN GRAM POSITIF YANG DIISOLASI DARI UDANG DOGOL (Metapenaeus monoceros), UDANG LOBSTER (Panulirus sp), DAN UDANG REBON (Mysis dan Acetes)

Abstrak

The research has been conducted to experiment an activity of antibacterial assay from water and ethanol garlic (Allium sativum L.) extract to Gram negative and Gram positive Bacteria isolated from Metapenaeus monoceros, Panulirus sp, Mysis and Acetes (Prawns). The research used factorial pattern Randomize Block Design which consisted of two factors and two replications. An assay bacteria are Bacillus sp, Streptococcus sp, Staphylococcus sp, Erysilopethrix sp (Gram positive) and Clostridium sp, Corynebacterium sp, Plesiomonas sp, Vibrio sp (Gram negative), have been used. The result showed that all concentrations of garlic ekstract with water and ethanol solvent has been influence the zone of inhibition from all bacteria. The pure garlic ekstract with concentration 75 % showed the best zona of inhibition to Streptococcus sp (28.25 mm), Clostridium sp (27,75 mm), and Plesiomonas sp (22.25 mm).
