Abstract
I PUTU ARDI JULIARTA. 2015. The Effect of Differences in Salinity on the Survival Rate and Growth of Polychaeta (Nereis sp.). Supervised by DODI HERMAWAN and MUSTAHAL. Polychaeta is a live food for tiger shrimp (Penaeus monodon) and pasific white shrimp (Litopenaeus vannamei) culture efforts Nereis sp. This is still very limited in Indonesia. Salinity is one of the parameters environmental conditions, salinity is vital to the survival rate and growth of Polychaeta. The aim of this research was to determine the best salinity maintenance in order to obtain the optimal survival rate and growth in the culture of Polychaeta. The research utilizing of salinity on Polychaeta culture has been done, with treatment using difference of salinity are 5 ppt, 10 ppt and 15 ppt with three times repeating of each treatment. The research has been done on July - August 2014 at the laboratory scale in Fishery Department Agriculture Faculty Sultan Ageng Tirtayasa University. The parameters of research were measured the survival rate, specific growth rate, feed efficiency and water quality. Then analyzed using a completely randomized design (CRD) and advanced test with Duncan. The results showed that treatment of salinity on survival rate parameters provide a significantly different effect (P <0.05) survival parameters treatment C 90.74% ± 3.20, treatment B 85.18% ± 3.21 and treatment A 66.67% ± 5.56. Specific growth rate parameters the effect was not significant (P>0.05) specific growth rate parameters treatment C 1.47% ± 0.73, treatment B 1.15% ± 0.91 and treatment A 0.86% ± 0.08. Feed efficiency parameters the effect was not significant (P> 0.05) feed eficiency parameters treatment C 5.23% ± 1.53, treatment B 4.79% ± 2.61 and treatment A 5.62% ± 0.19. The conclusions of the research showed that the difference in salinity of Polychaeta as maintenance medium having the same effect on the daily specific growth rate and feed efficiency of Polychaeta, the difference in salinity of Polychaeta maintenance media gives a difference effect on survival, specific growth rate and feed efficiency is 15 ppt optimal salinity.

| Additional Information: | Cacing laut merupakan pakan alami udang windu (Penaeus monodon) dan udang vaname (Litopenaeus vannamei). Upaya budidaya cacing laut ini masih sangat terbatas dilakukan di Indonesia. Hal ini karena masih minimnya informasi diantaranya data ekologi seperti kebiasaan makan, kepadatan biomassa dan kondisi lingkungannya. Tujuan penelitian ini untuk menentukan salinitas pemeliharaan terbaik sehingga diperoleh sintasan dan pertumbuhan yang optimal pada budidaya cacing laut Nereis sp. Penelitian dilaksanakan di Jurusan Perikanan, Fakultas Pertanian, Universitas Sultan Ageng Tirtayasa. Penelitian ini terdiri dari 3 perlakuan dengan masing-masing 3 kali ulangan. Perlakuan A salinitas 5 ppt, perlakuan B salinitas 10 ppt dan perlakuan C salinitas 15 ppt. Parameter penelitian yang diukur adalah sintasan, laju pertumbuhan spesifik, efisiensi pakan dan kualitas air. Data yang diperoleh kemudian dianalisis menggunakan (RAL) dan uji lanjut Duncan's Multiple Range menggunakan program komputer SPSS versi 16. Hasil penelitian menunjukkan bahwa sintasan memberikan pengaruh yang berbeda nyata (P<0,05), pada perlakuan C 90,74% ± 3,20, perlakuan B 85,18% ± 3,21 dan perlakuan A 66,67% ± 5,56. Laju pertumbuhan spesifik memberikan pengaruh yang tidak berbeda nyata (P>0,05), pada perlakuan C 1,47% ± 0,73, perlakuan B 1,15% ± 0,91 dan perlakuan A 0,86% ± 0,08. Efisiensi pakan memberikan pengaruh yang tidak berbeda nyata (P>0,05), pada perlakuan C 5,23% ± 1,53, perlakuan B 4,79% ± 2,61 dan perlakuan A 5,62% ± 0,19. Penelitian ini menyimpulkan bahwa perbedaan salinitas pemeliharaan cacing laut memberikan pengaruh yang sama terhadap laju pertumbuhan harian dan efisiensi pemberian pakan cacing laut, sedangkan perbedaan salinitas pemeliharaan cacing laut memberikan pengaruh yang berbeda terhadap sintasan sehingga untuk mengoptimalkan sintasan, laju pertumbuhan spesifik dan efisiensi pakan cacing laut pada pemeliharaannya bisa menggunakan salinitas 15 ppt. | |||||||||
