<p class="BasicParagraph" align="center"><strong>ABSTRACT</strong></p><p class="BasicParagraph" align="center"><strong> </strong></p><p class="BasicParagraph">The increasing demand of white shrimp <em>Litopenaeus vannamei</em> requires the application of intensive culture system. However, intensive culture system of white shrimp could increase the risk of disease outbreak. The application of sinbiotic may provide solution to the problem. This study was aimed to evaluate the effectiveness of the use of technical sinbiotic on the survival and growth of white shrimp in ponds. This study consisted of four treatments; treatment K (control), treatment A (probiotic 0.5% and prebiotic 1%), treatment B (probiotic 1% and prebiotic 2%), and treatment C (probiotic 2% and prebiotic 4%). The results showed that administration of sinbiotic had no significant differences on survival rate, growth rate, feed conversion ratio, size, and biomass of shrimp (P>0.05). However, based on analysis of business, sinbiotic A provided higher profits to the farmer (Rp10.230) compared to other symbiotic treatments and control.</p><p class="BasicParagraph"> </p><p class="BasicParagraph">Keywords: <em>Litopenaeus vannamei</em>, sinbiotic, technical media</p><p class="BasicParagraph"><strong> </strong></p><p class="BasicParagraph"><strong><br /></strong></p><p class="BasicParagraph" align="center"><strong>ABSTRAK</strong></p><p class="BasicParagraph"><strong> </strong></p><p class="BasicParagraph">Permintaan terhadap udang vaname <em>Litopenaeus vannamei</em> yang semakin meningkat membuat sistem budidaya udang sebaiknya menggunakan sistem budidaya intensif. Namun demikian sistem intensif pada budidaya udang vaname dapat meningkatkan risiko timbulnya penyakit. Penggunaan sinbiotik diharapkan dapat memberikan solusi dalam mengatasi masalah tersebut. Penelitian ini bertujuan untuk menguji efektivitas penggunaan sinbiotik teknis terhadap sintasan, pertumbuhan, dan keuntungan usaha udang vaname yang dipelihara di tambak. Penelitian ini terdiri atas empat perlakuan, yaitu perlakuan K (kontrol), perlakuan A (probiotik 0,5% dan prebiotik 1%), perlakuan B (probiotik 1% dan prebiotik 2%), dan perlakuan C (probiotik 2% dan prebiotik 4%). Hasil penelitian menunjukkan bahwa pemberian sinbiotik tidak berbeda nyata dalam nilai sintasan, laju pertumbuhan, rasio konversi pakan, <em>size</em>, dan biomassa udang (P>0,05). Namun demikian, berdasarkan analisis usaha perlakuan A memberikan keuntungan lebih tinggi (Rp10.230) dibandingkan dengan perlakuan sinbiotik lainnya serta kontrol.</p><p class="BasicParagraph"> </p><p class="BasicParagraph">Kata kunci: <em>Litopenaeus vannamei</em>, sinbiotik, media teknis</p><p> </p>
