      Abstract
      Pemberian pakan induk yang kurang lengkap kandungan nutrisinya akan mempengaruhi proses reproduksi. Proyek Akhir ini bertujuan untuk mengkaji pengaruh kombinasi jenis pakan tauge, ubi jalar putih dan pelet dengan vitamin E, untuk mempercepat kematangan gonad induk lobster air tawar. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari 5 perlakuan dengan 3 ulangan meliputi P1 (40 % tauge, 10 % pelet + vitamin, dan 50% ubi jalar putih), P2 (50% tauge, 25% pelet + vitamin E, dan 20% ubi jalar putih), P3 (25% tauge, 50 % pelet + vitamin E, dan 25% ubi jalar putih), P4 (25 % tauge , 25% pelet + vitamin E , dan 50% ubi jalar putih), dan kontrol (100% pelet). Pemberian pakan yang dikombinasikan memberikan pengaruh nyata (P<0,05) terhadap kinerja reproduksi. Hasil yang terbaik ditunjukkan oleh induk yang diberi perlakuan pakan P3, dengan laju kematangan gonad selama 26 hari, masa rematurasi 20 hari, ekunditas 934 butir/ekor, fertilization rate 97,84%, dan hatching rate 92,70%. Secara ekonomi, kombinasi pakan dapat meningkatkan profitabilitas usaha pembenihan lobster air tawar mencapai 60,18%.
       
      Feeding fish broodstock with inadequate nutritional content can adversely affect their reproductive processes. This final project aims to evaluate the effects of feeding with a combination of bean sprouts, white sweet potato, and pellets supplemented with vitamin E on accelerating gonad maturation in freshwater lobster broodstock. The study utilized a Complete Randomized Design (RAL) consisting of five treatments with three replicates: P1 (40% bean sprouts, 10% pellets + vitamins, and 50% white sweet potatoes), P2 (50% bean sprouts, 25% pellets + vitamin E, and 20% white sweet potatoes), P3 (25% bean sprouts, 50% pellets + vitamin E, and 25% white sweet potatoes), P4 (25% bean sprouts, 25% pellets + vitamin E, and 50% white sweet potato), and a control group (100% pellets). The combined feeding showed a significant effect (P<0.05) on reproductive performance. The best results were observed in the broodstock receiving the P3 treatment, with a gonad maturity rate of 26 days, a rematuration period of 20 days, fecundity of 934±36.74 eggs per broodstock, a fertilization rate of 97.84%, and a hatching rate of 92.70%. Economically, the combination of feeds can enhance the profitability of the freshwater lobster hatchery business by 60.18%.
