AbstrakUdang galah mengalami pertumbuhan setelah molting, untuk pengerasan kulit udang membutuhkan kalsium. Tulang ikan kambing-kambing mengandung banyak kalsium sehingga dapat mempercepat proses pengerasan kulit pada udang. Penelitian ini dilakukan untuk mengetahui penambahan kalsium tulang ikan kambing-kambing dapat meningkatkan pertumbuhan dan frekuensi molting udang galah. Penelitian ini menggunakan rancangan acak lengkap (RAL) dengan penambahan resirkulasi sebagai media dalam pemeliharaan kualitas air yang perlakuannya sebanyak empat perlakuan dan tiga ulangan yang terdiri dari A (0% CaO), B(1% CaO), C (2% CaO) dan D (3% CaO). Hasil penelitian menunjukkan bahwa penambahan kalsium berpengaruh nyata terhadap kelangsungan hidup udang galah yaitu A 90%, B 95%, C 90% dan D 97.5% dan pertumbuhan berat harian pada masing-masing perlakuan yaitu A 1.76 g, B 1.72 g, C 1.60 g, dan D 1.86. Pertumbuhan panjang harian yaitu A 1.23 cm, B 1.26 cm, C 1.23 cm dan D 1.06 cm dengan frekuensi molting udang galah tertinggi yaitu C 0.75 kali/ekor, D 0.63 kali/ekor, A 0.59 kali/ekor dan yang terendah pada perlakuan B 0.45 kali/ekor.Kata kunci: kalsium; kelangsungan hidup; pertumbuhan; udang galahAbstractGiant shrimp growth after the molting process, for hardening shrimp shell requires calcium. Kambing-kambing fish bones contains lots of calcium so that they do accelerate the process of hardening the shell-on shrimp. This study was conducted to detect addition of kambing-kambing fish bone calcium get increase the growth and the molting frequency of giant shrimp. This study used was Completely Randomized Design (CRD) with additions recirculation system as media a medium in maintaining water quality with four treatments and three replications consist is A (0% CaO), B (1% CaO), C (2% CaO) and dan D (3% CaO). The results showed that real participation in the survival of giant prawns, namely A 90%, B 95%, C 90% dan D 97.5% and daily weight growth in each treatment that is A 1.76 g, B 1.72 g, C 1.60 g, and D 1.86. Daily long growth that is A 1.23 cm, B 1.26 cm, C 1.23 cm and D 1.06 cm by means of molting frequency of giant shrimp has the highest of C 0.75 times/tail, D 0.63 times/individual, A 0.59 times/ individual and the lowest is by treatment B 0.45 times/ individual.Keywords: calcium; survival rate; growth; giant prawn
