Ikan mas merupakan salah satu jenis ikan konsumsi air tawar yang memiliki potensi pasar tinggi serta menarik minat pengusaha untuk membudidayakannya. Namun produksi ikan mas rentan terhadap serangan penyakit salah satunya penyakit Motil Aeromonas Septicemia (MAS) yang disebebkan oleh bakteri Aeromonas hydrophila. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian ekstrak daun belimbing wuluh (Averrhoa bilimbi L.) pada pengobatan ikan mas (Cyprinus carpio) yang terinfeksi bakteri Aeromonas hydrophila. Rancangan percobaan yang digunakan adalah rancangan acak lengkap (RAL) dengan enam perlakuan dan tiga kali ulangan. Adapun variabel perlakuan ekstrak daun belimbing wuluh antara lain adalah perlakuan A (Kontrol negatif), B (Kontrol positif), C (45 ppm), D (65 ppm), E (85 ppm), dan F (105 ppm) dengan metode maserasi. Berdasarkan hasil pengamatan gambaran darah pada ikan mas diperoleh jumlah leukosit, hemoglobin, dan hematokrit terbaik yaitu pada perlakuan F (105 ppm) dengan masing-masing nilai sebesar 3,04x104 sel/mm3 , 6,3 g/100 ml, dan 30,66%. Hasil uji ANOVA menunjukkan bahwa pemberian ekstrak daun belimbing wuluh berbeda nyata terhadap kelangsungan hidup ikan mas pada semua perlakuan yang diuji (P

Goldfish is one type of freshwater consumption fish that has high market potential and attracts entrepreneurs to cultivate it. However, goldfish production is vulnerable to disease attacks, one of which is Motil Aeromonas Septicemia (MAS) disease caused by Aeromonas hydrophila bacteria. This study aims to determine the effect of giving star fruit leaf extract (Averrhoa bilimbi L.) on the treatment of goldfish (Cyprinus carpio) infected with Aeromonas hydrophila bacteria. The experimental design used is a complete randomized design (CRD) with six treatments and three replicates. The treatment variables of star fruit leaf extract include treatment A (negative control), B (positive control), C (45 ppm), D (65 ppm), E (85 ppm), and F (105 ppm) with maceration method. Based on the observation of blood picture in goldfish, the best leukocyte count, hemoglobin, and hematocrit were obtained in treatment F (105 ppm) with each value of 3.04 x104 cells/mm3, 6.3 g/100 ml, and 30.66%. ANOVA test results showed that the provision of star fruit leaf extract was significantly different to the survival of goldfish in all treatments tested (P < 0.05). The best survival percentage was obtained in treatment F (105 ppm concentration of star fruit leaf extract) with a value of 76.33% while the lowest treatment was in the positive control treatment with a value of 33.33%. It can be concluded that the use of star fruit leaf extract as an antibacterial has an effect in the treatment of goldfish infected with Aeromonas hydrophila bacteria.
