Abstract

Melastoma herbal (Melastoma malabathricum) has antibacterial, antioxidant and cytotoxic properties. Using melastoma plants to increase fishery productivity has been widely studied. Herbs Melastoma can act as Immunostimulant, boosts the body^s immunity. The disease was a factor causing the decline in black tiger shrimp production in Tarakan, and the water carrying capacity factor has decreased. Diseases that often attack black tiger shrimp farmers are Vibrio spp. The study aims to know the potential of the melastoma leaf extract as an immunostimulant for black tiger shrimp fry against Vibrio parahaemolyticus bacteria attack. Tests on black tiger prawns in the post-larval stage (PL - 15) treated the food with Artemia saline enriched with melastoma leaf extract with different concentrations. The research consists of four treatments and three replications, such as- treatment 1 (administration of A. saline without enrichment), treatment 2 (enrichment of A. saline with 100 ppm extract), treatment 3 (enrichment of A. saline with extract of 120 ppm) and treatment 4 (enrichment of A. saline with extract of 150 ppm). The result shows the highest survival rate of post larvae in the treatment of A. saline enrichment with an extract concentration of 120 ppm, 64%. Meanwhile, the control treatment showed the lowest survival rate for fry, which was 34%. In addition, after 24 hours of V. parahaemolyticus infection in fry, the control treatment showed symptoms of an earlier attack than the extract treatment. Melastoma leaves can improve the fry^s immunity to dependent on Vibrio parahaemolyticus bacteria attack.
