Abstract
Udang Vaname (Litopenaeus vannamei) merupakan salah satu komoditas unggulan yang memiliki nilai ekonomis yang tinggi. Dalam proses budidaya sendiri dibagi menjadi berberapa bagian tingkatan berdasarkan kepadatannya yaitu ekstensif, semi intensif, intensif dan super intensif. System budidaya yang menerapkan tambak intensif dengan kepadatan yang tinggi diharapkan dapat memberikan keuntungan yang tinggi. Namun seringkali terjadi penurunan produksi dikarenakan kurangnya perencanaan yang terperinci dalam kegiatan budidaya sehingga kegiatan budiaya tidak terlaksana secara optimal. Penelitian ini dilaksanakan di tambak PT. Suri Tani Pemuka Unit Sobo, Kabupaten Banyuwangi, Jawa Timur. Metode pada penelitian ini dilaksanakan menggunakan metode statistic dengan rancangan penelitian berupa Rancangan Acak Lengkap (RAL) 2 perlakuan dan 3 ulangan. Proses pengambilan data dilakukan pada 6 kolam yang berbeda pada setiap perlakuan dengan masingmasing 3 kolam memiliki padat tebar yang sama. Pada kolam dengan perlakuan A sebesar 150 ekor/m2 sedangkan pada perlakuan B sebesar 167 ekor/m2. Analisa penelitian yang dilakukan menggunakan analisis normalitas dan homogenistas lalu dilanjutkan dengan Uji-T (independent sample test). Penelitian tersebut dilakukan terhadap Tingkat Keberlangsungan Hidup (SR), Laju Pertumbuhan Spesifik (SGR), Rasio Konversi Pakan (FCR), Produktivitas, Total Bacteria Count (TBC) dan Total Vibrio Count (TVC) pengaruhnya terhadap produksi udang vaname. Hasil penelitian menujukan pengaruh padat tebar udang vaname tidak berpengaruh secara signifikan terhadap produktivitas, baik terhadap nilai Tingkat Keberlangsungan Hidup (SR), Laju Pertumbuhan Spesifik (SGR), Rasio Konversi Pakan (FCR), Produktivitas, Total Bacteria Count (TBC) dan Total Vibrio Count (TVC). Adapun nilai SR tertinggi berada pada perlakuan B sebesar 81,7 ± 4,8%, nilai SGR tertinggi berada pada perlakuan A sebesar 4,13 ± 1,12 %bb/hari, nilai FCR terendah berada pada perlakuan A dengan nilai 1,29 ± 0,36, nilai produktivitas tertinggi berada pada perlakuan A dengan nilai 1.304,417 ± 486,29 kg/ha, nilai TBC tertinggi pada perlakuan B 3,6 x 106 ± 3,1 x 104 CFU/ml, nilai vibrio kuning tertinggi berada pada perlakuan A sebesar 2,8 x 103 ± 5,4 x 102 CFU/ml dan nilai vibrio hijau tertinggi pada perlakuan B sebesar 2,5 x 102 ± 2,0 x 102 CFU/ml. Adapun untuk semua parameter kualitas air termasuk dalam kisaran optimal dan masih dapat ditoleransi oleh udang vaname.
English Abstract
Vaname Shrimp (Litopenaeus vannamei) is one of the leading commodities that has high economic value. In the cultivation process itself is divided into several levels based on the density, there are: extensive, semi-intensive, intensive and super intensive. Cultivation systems that apply intensive ponds with high density are expected to provide high profits. However, production declines often occur due to lack of detailed planning in cultivation activities so that cultivation activities are not carried out optimally. This research was conducted in PT. Suri Tani Sobo Unit, Banyuwangi Regency, East Java. The method in this study was carried out using statistical methods with a research design in the form of a completely randomized design (RAL) with 2 treatments and 3 replications. The data collection process was carried out on 6 different ponds in each treatment with 3 ponds each having the same stocking density. In the pond with treatment A of 150 fish/m2 while in treatment B of 167 fish/m2. The analysis of the research was carried out using normality and homogeneity analysis and then continued with the T-test (independent sample test). The research was conducted on the Survival Rate (SR), Specific Growth Rate (SGR), Feed Conversion Ratio (FCR) and Productivity of the Effect on Vannamei Shrimp Production. The results showed that the stocking density of vaname shrimp had no significant effect on productivity, both on the value of Survival Rate (SR), Specific Growth Rate (SGR), Feed Conversion Ratio (FCR) and Productivity. The highest SR value was in treatment B of 81.7 ± 4.8%, the highest SGR value was in treatment A of 4.13 ± 1.12 %ww/day, the lowest FCR value was in treatment A with a value of 1.29 ± 0.36, the highest productivity value was in treatment A with a value of 1.304,417 ± 486.29 kg/ha, the highest TBC value was in treatment B 3.6 x 106 ± 3.1 x 104 CFU/ml, the highest value of yellow vibrio was in treatment A of 2.8 x 103 ± 5.4 x 102 CFU/ml and the highest green vibrio value was in treatment B of 2.5 x 102 ± 2.0 x 102 CFU/ml. As for all water quality parameters included in the optimal range and can still be tolerated by white shrimp.
