【 摘 要 】

Saprolegnia SP. is a fungi which is opportunistic and generally as a secondary pathogen on fish. Saprolegnia sp. infects epidermis tissue that begins at the head or fins and can spread over the entire surface of the body. The result of the using of chemicals to control infections of Saprolegnia spp. can cause pollution of the environment and harm the consumer. The purpose of this research was to determine the potential and the minimum concentration of extracts basil leaves (Ocimum sanctum Linn) as antifungi against the growth of Saprolegnia sp. by vitro. The research was held in Fish Quarantine Kelas I Juanda Suarabaya in January 2015. A positive result was obtained in the test of the effectiveness of basil leaves in inhibiting the growth of the fungus Saprolegnia sp. Concentration of the extract given to treatment 90% and 100% was able to inhibit the growth of Saprolegnia sp., indicated by the formation of the inhibitory zones at a concentration of treatment, and had the best results on the concentration of 100%.
