EFEKTIVITAS PEMBERIAN PROBIOTIK MELALUI PAKAN TERHADAP PRODUKSI UDANG VANAMELitopenaeus vannamei DI TAMBAK

Abstract

Penelitian ini bertujuan untuk mengetahui efektivitas pemberian probiotik melalui pakan terhadap pertumbuhan dan produksi udang vaname (Litopenaeus vannamei). Metode yang digunakan yaitu ex post facto dengan tiga perlakuan, yaitu P1 (kontrol tanpa probiotik), P2 (penambahan probiotik 125 mL/L), dan P3 (penambahan probiotik 200 mL/L). Probiotik yang digunakan mengandung bakteri Bacillus sp. dan Lactobacillus sp. yang dicampur ke dalam pakan dan difermentasi selama 24 jam. Hasil penelitian menunjukkan bahwa pemberian probiotik melalui pakan memberikan pengaruh nyata terhadap pertumbuhan dan efisiensi pakan udang vaname. Perlakuan P3 menghasilkan performa terbaik untuk biomasa, LPH dan FCR dibandingkan perlakuan lainnya. Dosis probiotik 200 mL/L direkomendasikan untuk diterapkan pada skala budidaya komersial.

This study aimed to determine the effectiveness of probiotic supplementation through feed on the growth and production of whiteleg shrimp (Litopenaeus vannamei). The research employed an ex post facto method with three treatments: P1 (control without probiotics), P2 (addition of 125 mL/L probiotics), and P3 (addition of 200 mL/L probiotics). The probiotics used contained Bacillus sp. and Lactobacillus sp., which were mixed into the feed and fermented for 24 hours. The results showed that probiotic supplementation through feed had a significant effect on the growth and feed efficiency of L. vannamei. The P3 treatment produced the best performance in terms of biomass, specific growth rate (SGR), and feed conversion ratio (FCR) compared to other treatments. A probiotic dosage of 200 mL/L is recommended for application in commercial, scale aquaculture.
