(Pranata Fadli Husada. 26020118140070. Pengaruh Ekstrak Bawang Putih (A. sativum) Terhadap Daya Tetas Telur dan Kelulushidupan Larva Ikan Tawes (B. gonionotus) Tristiana Yuniarti dan Istiyanto Samidjan).
Penelitian ini bertujuan untuk mengetahui pengaruh dan konsentrasi optimum ekstrak bawang putih (A. sativum) terhadap daya tetas telur dan tingkat kelulushidupan lava ikan tawes (B. gonionotus). Penelitian ini dilaksanakan pada tanggal 15 Agustus – 6 Septemer 2022 di LPKIL Muntilan, Magelang, Jawa Tengah. Bahan uji yang digunakan adalah bawang putih, etanol dan telur ikan tawes yang berasal dari LPKIL Muntilan, Magelang. Metode yang digunakan adalah eksperimen dengan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan masing-masing 3 ulangan. Media penetasan ditambahkan ekstrak bawang putih (A. sativum) dengan konsentrasi A (0 ml/l), B (3 ml/l), C (4 ml/l), dan D (5 ml/l),
kemudian telur sebanyak 100 butir setiap ulangan direndam di dalamnya selama 30 menit lalu dipindahkan ke wadah penetasan. Data yang diamati adalah fase perkembangan telur, lama waktu penetasan telur, daya tetas telur (HR), kelulushidupan (SR), dan kualitas air. Hasil penelitian menunjkan bahwa perendaman ekstrak bawang putih berpengaruh terhadap daya tetas telur dan
kelulushidupan larva ikan tawes. Hasil nilai daya tetas telur (HR) secara berturut-turut dari perlakuan A sampai dengan perlakuan D yaitu 66,67±3,06%, 83,00±2,65c%, 85,33±1,53c%, 74,67±2,08b%, sedangkan untuk nilai kelulushidupan (SR) secara berturut-turut dari perlakuan A sampai dengan perlakuan D yaitu 60,93±2,73a%, 72,78±4,63bc%, 77,29±4,80c%, 69,61±2,23%. Penelitian menunjukkan bahwa perendaman telur dengan ekstrak bawang putih berpengaruh nyata (P˂0,05) terhadap daya tetas telur (HR) dan kelulushidupan (SR) larva ikan tawes. Dosis optimum perendaman telur dengan ekstrak bawang putih terhadap daya tetas telur dan kelulushidupan larva ikan tawes yaitu 2,94 – 3,25 ml/l.

ABSTRACT
(Pranata Fadli Husada. 26020118140070. Effect of Garlic Extract (A.
sativum) on Egg Hatching and Larvae Life of Tawes (B. gonionotus) Tristiana Yuniarti and Istiyanto Samidjan).
This study aims to determine the effect and optimum concentration of garlic extract (A. sativum) on egg hatchability and survival rate of tawes (B. gonionotus) lava. This research was conducted on August 15 – September 6 2022 at LPKIL Muntilan, Magelang, Central Java. The test materials used were garlic, ethanol and tawes fish eggs from LPKIL Muntilan, Magelang. The method used was an experiment with a completely randomized design (CRD) with 4 treatments and 3 replications each. The hatching medium was added with garlic extract (A. sativum)
with concentrations A (0 ml/l), B (3 ml/l), C (4 ml/l), and D (5 ml/l), then 100 eggs. the grains of each replicate were soaked in it for 30 minutes and then transferred to the hatching container. The data observed were egg development phase, egg hatching time, egg hatchability (HR), survival rate (SR), and water quality. The
results of the study showed that soaking garlic extract had an effect on egg hatchability and tawes larvae survival. The results of egg hatchability (HR) successively from treatment A to treatment D were 66.67 ± 3.06a%, 83.00 ±2.65c%, 85.33 ± 1.53c%, 74.67 ±2.08b%, while the survival rate (SR) respectively from treatment A to treatment D is 60.93 ± 2.73a%, 72.78 ± 4.63bc%, 77.29 ± 4.80c
%, 69.61±2.23b%. The research showed that soaking eggs with garlic extract had a significant effect (P˂0.05) on egg hatchability (HR) and survival (SR) of tawes larvae. The optimum dose of soaking eggs with garlic extract on egg hatchability and survival of tawes larvae is 2.94 – 3.25 ml/l.
Keywords: Barbonymus gonionotus, Allium sativum, egg hatchability
