      Abstract
      Serangan bakteri Aeromonas hydrophila merupakan salah satu kendala utama dalam budidaya ikan nila, karena menyebabkan penyakit Motile Aeromonas Septicaemia dengan mortalitas yang tinggi. Penelitian ini bertujuan menguji efektivitas ekstrak daun kelor, Lactobacillus plantarum, serta kombinasinya sebagai upaya pencegahan infeksi bakteri A. hydrophila pada ikan nila. Metode yang digunakan adalah rancangan acak lengkap dengan lima perlakuan dan tiga ulangan, meliputi kontrol positif, kontrol negatif, ekstrak daun kelor 0,5 mL 100 g?¹ pakan, L. plantarum (108 CFU mL?¹) 1 mL 100 g?¹ pakan, serta kombinasi keduanya. Ikan nila berbobot awal 7,286 ± 0,003 g dipelihara selama 45 hari dan diuji tantang menggunakan A. hydrophila. Perlakuan kombinasi memberikan hasil terbaik dengan laju pertumbuhan harian tertinggi yaitu 0,59 g hari-1, rasio konversi pakan terendah 1,07, dan kelimpahan bakteri asam laktat usus tertinggi (7,14 ± 0,01 log CFU g-1). Setelah uji tantang, perlakuan kombinasi juga mampu mempertahankan kondisi hematologi, meningkatkan respon imun nonspesifik, dan menghasilkan tingkat kelangsungan hidup tertinggi dan berbeda signifikan dibandingkan perlakuan kontrol dan lainnya. Kesimpulan penelitian ini adalah perlakuan kombinasi ekstrak daun kelor dan L. plantarum mampu memodulasi respons imun nonspesifik yang memberikan perlindungan efektif terhadap infeksi bakteri A. hydrophila dengan tingkat kelangsungan hidup mencapai 93,3%.
       
      Aeromonas hydrophila bacterial attack is a major obstacle in tilapia cultivation because it causes Motile Aeromonas Septicemia disease and high mortality. This study aims to test the effectiveness of Moringa leaf extract, Lactobacillus plantarum, and their combination as an effort to prevent A. hydrophila bacterial infection in tilapia. The method used was a completely randomized design with five treatments and three replications, including positive control, negative control, Moringa leaf extract 0,5 mL 100 g?¹ feed, L. plantarum (108 CFU mL?¹) 1 mL 100 g?¹ feed, and a combination of both. Tilapia with an initial weight of 7,286 ± 0,003 g were raised for 45 days and challenged using A. hydrophila. The combination treatment gave the best results with the highest daily growth rate of 0,59 g day-1, the lowest feed conversion ratio of 1.07, and the highest abundance of intestinal lactic acid bacteria (7,14 ± 0,01 log CFU g-1). After the challenge test, the combination treatment was also able to maintain hematological conditions, increase nonspecific immune responses, and produce the highest survival rate and was significantly different compared to the control and other treatments. The conclusion of this study is that the combination treatment of Moringa leaf extract and L. plantarum is able to modulate nonspecific immune responses which provide effective protection against A. hydrophila bacterial infection with a survival rate of 93,3%.
