Viterna merupakan suplemen pakan ternak yang berperan untuk meningkatkan nafsu makan dan daya tahan tubuh, memacu enzim-enzim pencernaan serta mempercepat pertumbuhan ikan. Penelitian ini bertujuan untuk mengetahui pengaruh pengkayaan tubifex sp. dengan viterna dan ekstrak daun karamunting pada kelangsungan hidup dan pertumbuhan ikan cupang. Metode penelitian ini menggunakan metode rancangan acak lengkap dengan 4 perlakukan dan 3 ulangan. Perlakuan yang diujicobakan adalah pemberian Tubifex sp tanpa viterna dan ekstrak (kontrol), P1= Pemberian Tubifex sp. yang diperkaya viterna sebanyak 10ml + ekstrak dengan konsentrasi 250 ppm, P2= pemberian Tubifex sp yang diperkaya viterna sebanyak 15ml dan ekstrak dengan konsentrasi 250 ppm, dan perlakuan P3 yaitu pemberian Tubifex sp yang diperkaya viterna sebanyak 20ml + ekstrak dengan konsentrasi 250 ppm. Berdasarkan hasil penelitian ini menunjukan bahwa perlakuan pemberian Tubifex sp. yang diperkaya viterna sebanyak 15ml + ekstrak dengan konsentrasi 250 ppm menunjukan hasil yang lebih baik dibandingkan dengan perlakuan lainnya. Uji statistic menunjukkan beda nyata pada pertumbuhan panjang dan berat mutlak serta SGR (Specific Growth Rate) pada perlakuan pengkayaan cacing sutera menggunakan viterna dan ekstrak daun karamunting pada pertumbuhan ikan cupang (Betta splendens) dibandingkan perlakuan kontrol. Data pengukuran kualitas air yaitu suhu 27-280C, nilai pH 6-7 dan nilai amoniak 2,55 mg/l, menunjukkan masih dalam ambang normal. Berdasarkan hasil penelitian maka dapat disimpulkan bahwa penambahan Tubifex sp dan ekstrak karamunting dapat meningkatkan pertumbuhan ikan cupang (Betta splendens).

Viterna is an animal feed supplement that plays a role in increasing appetite and endurance, stimulating digestive enzymes and accelerating growth. This study aims to determine the effect of enrichment of tubifex sp. with viterna and karamunting leaf extract on the survival and growth of betta fish. This research method uses a completely randomized design method with 4 treatments and 3 replications. The treatments that were tested were administration of Tubifex sp without viterna and extract (control), P1 = Administration of Tubifex sp. which was enriched with 10 ml of Viterna + extract with a concentration of 250 ppm, P2 = administration of Tubifex sp. which was enriched with Viterna of 15 ml and extract with a concentration of 250 ppm, and the P3 treatment was administration of Tubifex sp. which was enriched with Viterna of 20 ml + extract with a concentration of 250 ppm. Based on the results of this study showed that the treatment of Tubifex sp. which enriched with 15 ml of Viterna + extract with a concentration of 250 ppm showed better results compared to other treatments. The statistical test showed a significant difference in the absolute length and weight growth and SGR (Specific Growth Rate) in the silkworm enrichment treatment using viterna and karamunting leaf extract on the growth of betta fish (Betta splendens) compared to the control treatment. Water quality measurement data, namely temperature 27-280C, pH value 6-7 and ammonia value 2.55 mg/l, showed that it was still within the normal threshold. Based on the results of the study, it can be concluded that the addition of Tubifex sp. and karamunting extract can increase the growth of Betta fish (Betta splendens). keywords: viterna, karamunting extract, betta fish (betta splendes)
