【 摘 要 】

Litopenaeus vannamei shrimp is one of the leading export commodities in fisheries from Indonesia, however White Feces Diseases (WFD) cause deaths up to 30% and decrease their growth and production. WFD is caused by the accumulation of several Vibrio bacteria in shrimp water and intestines. One of the local herbs that has the potential as antiproliferation, antidiabetic, anticytotoxic commonly used in the treatment of humans diseases is Physalis angulata known as ciplukan. The aim of this study was to obtain ciplukan extract which has an antibacterial activity of Vibrio sp., and to analyze the anti-bacterial effect of ciplukan extract on Vibrio bacteria from vannamei infected with WFD. This study used descriptive and experimental methods using a randomized block design. Data collection methods were carried out through direct observation of the object under study. Observation data were analyzed by F- test followed by HSD. The results showed that the extract of ciplukan plants contained antibacterial active ingredients. Chloroform solvent extracts had the best antibacterial activity with 13 mm inhibition zone on green bacterial colonies and 16.5 mm in yellow bacterial colonies derived from shrimp intestinal infected with WFD. The best concentration that provides the highest inhibition zone as obtained by 10% chloroform extract.
