Abstrak

Penelitian ini bertujuan untuk menguji pengaruh pemberian bakteri Bacillus coagulans dengan dosis yang berbeda pada pakan terhadap Imunitas Non Spesifik Udang Vaname. Metode pemberian bakteri Bacillus coagulans dengan cara penyemprotan ke pakan komersil dengan FR 2,1%. Udang vaname yang digunakan berukuran 13,1 ±0,06 gr sebanyak 10 ekor tiap akuarium. Akuarium berukuran 50cm x 40cm x 40cm berjumlah 12 buah (4 perlakuan dan 3 kali ulangan). Perlakuan K (kontrol), perlakuan A (dosis bakteri 104 CFU ml-1), B (dosis bakteri 106 CFU ml-1) dan C (dosis bakteri 108 CFU ml-1). Penelitian dilakukan selama 20 hari masa pemeliharaan dengan parameter uji total haemocyte count (THC), differential haemocyte count (DHC) dan aktifitas phagositosis (AP). Hasil penelitian menunjukan bahwa Pemberian bakteri Bacillus coagulans pada pakan memiliki pengaruh terhadap imunitas nonspesifik udang vaname. Ketiga dosis bakteri Bacillus coagulans 104 CFU ml-1, 106 CFU ml-1 dan 108 CFU ml-1 memberikan hasil terbaik selama pemeliharaan. Kata kunci: Udang Vaname, Bacillus coagulans, Total Haemocyte Count (THC), Differential Haemocyte Count (DHC) Dan Aktifitas Phagositosis (AP). abstract The purpose of this research is to examine the influence bacterial distribution of Bacillus coagulans with the different doses on feed towards non- specific immun of vaname shrimp. Method of distribution of Bacillus coagulans bacteria is by spraying into commercial feed with FR 2,1%. The vaname shrimp used is 13.1 ± 0.06 gr as much as 10 shrimp per aquarium. The aquarium measuring 50cm x 40cm x 40cm which is used amounted to 12 pieces for 4 treatments and 3 repetitions. Treatment K (control), treatment A (bacterial dose 104 CFU ml-1), B (bacterial dose 106 CFU ml-1) and C (bacterial dose 108 CFU ml-1). The research is conducted for 20 days of maintenance period with total haemocyte count (THC), differential haemocyte count (DHC) and activity of phagositosis (AP). The results showed that Bacillus coagulans bacteria feeding had an influence on nonspecific immunity of vaname shrimp. The three doses of Bacillus coagulans 104 CFU ml-1, 106 CFU ml-1 and 108 CFU ml-1 gave the best results during maintenance. Keywords: Vaname Shrimp, Bacillus coagulans, Total Haemocyte Count (THC), Differential Haemocyte Count (DHC) And Activity of Phagositosis (AP).
