THE EFFECTIVENESS OF WHITE TURMERIC EXTRACT (Curcuma zedoaria) AGAINST THE IMMUNE SYSTEM OF VANNAMEI SHRIMP (Litopenaeus vannamei)

Vannamei shrimp entered Indonesia to replace tiger prawns (Penaeus monodon), which then experienced disease attacks and decreased quality. However, with various advantages, the cultivation of vaname shrimp still has problems during the cultivation period. Therefore, this study will determine the effect of adding white turmeric extract (Curcuma zedoaria) on the immune system of vannamei shrimp (Litopenaeus vannamei). This research was carried out for 60 days using experimental research methods, and the research design used was a completely randomized design (CRD) consisting of 4 treatments with 3 replications were P1: Artificial feed infection, P2: Artificial feed +0, 5% white turmeric extract, P3: Artificial Feed+1% white turmeric extract, P4: Artificial Feed+2% white turmeric extract. The results showed that administration of white turmeric extract (Curcuma zedoaria) with a dose of 1% gave the best results and natural effect on the survival rate of 83.3%, Total Haemocyte Count of 1.4x107 cells/mL, and Differential Haemocyte Count (hyaline cells). In addition, by 23%, semi-granulocytes by 18.3%, and granulocytes by 58.7%, which play a role in the immune system of white vaname shrimp. In addition, the value of phagocytic activity was 68.8%.
