Abstract
Abstrak Kalsium merupakan salah satu makromineral yang berperan penting dalam proses pengerasan kulit udang pasca molting. Pada tambak salinitas rendah, sering mengalami kekurangan kalsium yang dapat berdampak pada kegagalan molting udang bahkan menyebabkan kematian. Penelitian ini bertujuan untuk mengkaji pertumbuhan, tingkat kelangsungan hidup, dan rasio konversi pakan udang vaname (Litopenaeus vannamei) yang dipelihara pada media kultur salinitas rendah dengan penambahan konsentrasi mineral kalsium berbeda. Penelitian ini dilakukan pada media bersalinitas 5 ppt, menggunakan rancangan acak lengkap (RAL) dengan 4 perlakuan dan 3 ulangan. Perlakuan tersebut berupa penambahan makromineral kalsium yang berbeda, yaitu: A (0 mg/L), B (50 mg/L), C (100 mg/L), dan D (150 mg/L). Hasil penelitian menunjukkan bahwa penambahan kalsium yang berbeda pada media salinitas rendah berpengaruh terhadap pertumbuhan, tingkat kelangsungan hidup, dan rasio konversi pakan udang vaname. Pertumbuhan terbaik terjadi pada perlakuan penambahan kalsium 0 mg/L (kontrol) yaitu sebesar 0,56±0,18 g, sementara tingkat kelangsungan hidup dan konversi pakan terbaik terjadi pada perlakuan 50 mg/L yaitu 54,3±0,38% dan 1,4±0,1. Kata kunci : makromineral, molting, pertumbuhan, tingkat kelangsungan hidup Abstract Calcium is one of the macrominerals that plays an important role in the process of hardening of the shrimp shell after molting. In low salinity ponds, there is often a lack of calcium which can have an impact on shrimp molting failure and even cause death. This study aimed to assess the growth, survival rate, and feed conversion ratio of vaname shrimp (Litopenaeus vannamei) reared in low salinity culture media with the addition of different concentrations of calcium minerals. This study was conducted on 5 ppt salinity media, using a completely randomized design (CRD) with 4 treatments and 3 replications. The treatment was the addition of different calcium macrominerals, namely: A (0 mg/L), B (50 mg/L), C (100 mg/L), and D (150 mg/L).The results showed that the addition of different calcium in low salinity media affected the growth, survival rate, and feed conversion ratio of vaname shrimp. The best growth occurred in the 0 mg/L calcium treatment (control) which was 0.56±0.18 g, while the best survival rate and feed conversion occurred in the 50 mg/L treatment which was 54.3±0.38% and 1.4±0.1. Keywords : macromineral, molting, growth rate, survival rate
