Dwi, Kadek Bella (2017) Pengaruh Salinitas Yang Berbeda Terhadap Kelangsungan Hidup Dan Laju Pertumbuhan Larva Teripang Pasir (Holothuria Scabra) Fase Penempelan. Sarjana thesis, Universitas Brawijaya.
Abstract
Teripang pasir (H. scabra) merupakan biota komoditas ekonomis tinggi baik di pasaran domestik maupun internasional. Besarnya penangkapan membuat populasi teripang pasir menurun sehingga teripang pasir makin sulit didapatkan. Keterbatasan benih dari alam dikarenakan usaha pembenihan teripang di Indonesia belum dapat berproduksi secara massal. Proses pembenihan dipengaruhi oleh beberapa faktor salah satunya adalah salinitas Sehingga perlu dilakukan penelitian tentang pengaruh salinitas yang berbeda terhadap sintasan dan laju pertumbuhan larva teripang pasir sehingga dapat menghasilkan juvenil yang baik, perkembangan larva yang baik, sintasan larva yang tinggi serta laju pertumbuhan yang baik. Metode yang digunakan adalah metode eksperimental dengan 5 perlakuan A (20 ppt), B (25 ppt), C (30 ppt), D (40 ppt), K (35 ppt) dan 3 kali ulangan. Penelitian dilakukan di Balai Bio Industri Laut LIPI Lombok Utara pada bulan Februari hingga Mei 2017. Hasil penelitian disimpulkan bahwa salinitas berpengaruh terhadap jumlah individu, kelangsungan hidup dan laju pertumbuhan larva. Perlakuan C (30 ppt) dengan kelangsungan hidup paling tinggi yaitu 3,23 + 2,85 % dan laju pertumbuhan tertinggi pada perlakuan C (30 ppt) sebesar 2,66 + 0,23 %.
English Abstract
Sea Cucumber (H. scabra) is a high economic commodity biota both in domestic and international market. The size of the catch makes the sand cucumber population decreased so that the sea cucumber is more difficult to obtain. Limitations of the seeds of nature because the hatchery of sea cucumbers in Indonesia has not been able to produce in bulk. Seeding process is influenced by several factors one of which is salinity. So it is necessary to research about the effect of different salinity on the synthesis and growth rate of sea cucumber larvae so as to produce good juvenile, good larvae development, high larval larvae and good growth rate. The method used was experimental method with 5 treatment A (20 ppt), B (25 ppt), C (30 ppt), D (40 ppt), K (35 ppt) and 3 replications. The study was conducted at Balai Bio Laut Laut LIPI North Lombok from February to May 2017. The results concluded that salinity affect the number of individuals, survival and larval growth rate. The treatment of C (30 ppt) with the highest survival was 3.23 + 2.85% and the highest growth rate in the C treatment (30 ppt) was 2.66 + 0.23%.
