Abstract

The aims of this research was to determine the immunogenicity of inactivated vaccine A. salmonicida whole cell in common carp and the best mothod in vaccine administration. Vaccine was produced by inactivated A. salmonicida with adding 1 ppm (v/v) formaldehide and incubated for 24h in room temperature. Ten juvenil of carp (Vaccine was administrated in each 10 fish by injection intraperitoneally (107 cfu/fish), orally (107 cfu/fish), immersion (107 cfu/ml for 30 minute) and control (fish with no vaccination). Booster was conducted 7 days after first vaccination with same dossage and method. Titer antibody was evaluated in three times i.e. before vaccination, 7th days after first vaccination, and 7th days after booster. Water quality such as dissolved oxygen, pH, and water temperature was measured as a supported parameters. Results showed that titer antibodi for all treatment before vaccination was 1/6. However, titer antibody after vaccination and booster increased to 1/58.67 and 1/85.33 for i.p injection, 1/42.67 and 1/64 for oral, 1/24 and 42.67 for immerse, respectively. Whereas, there was no significantly increasing of titer antibody in control that was 1/9.33 and 1/18.67 for vaccination and bosster, respectively. Vaccine adminsitration method by injection i.p. was the best method for obtain the best immunogenicity of vaccine. Water quality parameters along this experiment still in optimum range for common carp living.

Abstract

Metil metsulfuron merupakan senyawa aktif yang umum digunakan oleh para petani untuk membasmi gulma di sawah. Penggunaan yang tidak sesuai pada senyawa aktif tersebut akan menyebabkan resiko pencemaran lingkungan yang berpengaruh terhadap kondisi organisme non target disekitarnya seperti gangguan reproduksi pada Daphnia sp. Penelitian ini bertujuan untuk mengetahui tingkat toksisitas metil metsulfuron dengan menentukan nilai LC50-48 jam terhadap Daphnia sp. serta mengetahui rasio jenis kelamin jantan anakan Daphnia sp. Adapun metode yang digunakan dalam penelitian ini adalah pemberian senyawa aktif metil metsulfuron dengan konsentrasi yang berbeda. Pada uji toksisitas akut menggunakan konsentrasi 0 ppm; 20,89 ppm; 43,64 ppm; 91,17 ppm; 190,48 ppm dan 397,96 ppm. Sedangkan pada uji pengaruh metil metsulfuron terhadap rasio anakan jantan Daphnia sp. yaitu 0 ppm; 20 ppm; 40 ppm dan 80 ppm. Hasil penelitian pada uji toksisitas menunjukkan nilai (LC50)-48 jam sebesar 140,2 ppm sedangkan persentase rasio anakan jantan Daphnia sp. tertinggi terdapat pada perlakuan 80 ppm yaitu mencapai 71%. Hubungan antara konsentrasi metil metsulfuron dengan rasio anakan jantan Daphnia sp. menunjukkan bahwa semakin tinggi konsentrasi metil metsulfuron yang dipaparkan pada Daphnia sp., maka semakin meningkat pula rasio anakan jantan Daphnia sp. yang dihasilkan.

Abstract

Patin Siam (Pangasius hypopthalamus) is a freshwater fish which is received considerable attention by public and has high economic value. In process of cultivation, farmers often got problems because of high price of feed. It’s because raw materials feed such fish meal still import from another country. One of the efforts to reduce the use of imported fish meal is using Petek fish meal. The aim of this research was to determine the effect of the use of Petek fishmeal as partial substitution of fish meal. This research used Completely Randomized Design (CRD) with 5 treatments and 3 replications namely treatment A (commercial pellets / control), B (fish meal 75% + Petek fish meal 25%), C: (fish meal 50% + Petek fish meal 50%), D (25% fish meal + 75% Petek fish meal) and E: (0% fish meal + Petek fish meal 100%). Observed variables were absolute growth, daily growth rate, survival rate, and feed conversion ratio (FCR). Data were analyzed by ANOVA and Duncan test. The tested fish were cultivated in aquarium with dimension of 60 x 40 x 40 cm3 for 50 days. Fishes were feed three times a days with feeding rate of 5%. The results showed that the use of Petek fishmeal in feed could increase absolute growth and daily growth rate. The treatment of C resulted in highest absolute growth of Patin Siam and lowest feed conversion ratio. The treatments did not effect the survival rate of Patin Siam.

Abstract

Dampak kenaikan permukaan air laut (sea level rise/SLR)  di pesisir Kabupaten Tuban diprediksi terbagi menjadi 3 kelompok yaitu kemunduran garis pantai, penggenangan, dan intrusi air laut.   Untuk mengetahui gejala intrusi air laut yang terjadi di pesisir Kabupaten Tuban ini diperlukan  pemetaan sebaran air tanah asin hingga payau. Penelitian dilakukan dengan mengambil air sampel pada 100 titik di  beberapa sumur gali maupun sumur bor yang tersebar pada akuifer dangkal dan dalam di 5 Kecamatan yang ada di kabupaten Tuban yang meliputi kecamatan Bancar, Tambakboyo, Jenu, Tuban dan Palang dengan jarak 200 -300 m dari garis pantai. Selanjutnya  air sampel yang diambil dilakukan pengukuran Daya Hantar Listrik (DHL). Hasil nilai pengukuran DHL kemudian di bentuk peta sebaran nilai DHL untuk mengetahui klasifikasi tingkat keasinan air tanah yang ada di daerah pesisir Kabupaten Tuban. Selanjutnya sampel dianalisa di laboratorium untuk mengetahui kandungan ion Carbonat (CO3), Bicarbonat (HCO3), Khlorida (Cl).  Indikasi adanya penyusupan air laut ditentukan berdasarkan nilai perbandingan kadar ion Khlorida (Cl) terhadap jumlah ion karbonat (HCO3-1 + CO3-2). Peta sebaran nilai DHL di Kabupaten Tuban antara 900-1500 (sifat air: air tawar) yaitu Kecamatan Bancar, Jenu, Tuban, sedangkan <1500 – 1800 (sifat air: air agak payau) yaitu Jenu, Tambakboyo, Bancar. Tingakt intrusi yang terjadi kategori sedikit dan sedang yaitu hamper di 4 kecamatan pantai (Bancar, Tambakboyo, Jenu, Palang) sedang kecamatan Tuban masih air tawar. Nilai DHL lebih dari 1500 µS/cm terdapat  di empat kecamatan (Bancar, Tambakboyo, sebagian Jenu, dan palang). Wilayah tersebut memiliki jarak dengan laut cukup dekat, namun pada beberapa tempat dilokasi tersebut juga masih ditemukan kondisi air yang tidak asin. Daerah sebaran air tanah agak payau menempati akuifer berupa lempung pasiran yang merupakan endapan alluvial dengan permeabilitas umumnya rendah dan topografi permukaan tanah datar hingga landai, sehingga sangat rentan terhadap intrusi air laut. Air tanah agak payau didominasi oleh akuifer berupa pasir gampingan hingga lempung gampingan, namun sebagian juga masih masuk ke dalam sistem akuifer endapan alluvial. Selain perbedaan sistem batuan penyusun akuifer jarak antara sumur dengan air laut juga menjadi salah satu faktor penyebab perbedaan tingkat keasinan air tanah.

Abstract

Increased immunity shrimp became one of the targets of feeding with a complete nutrient constituent composition. Shrimp have a different immune system compared to fish in general and can be increased quickly by providing the right nutrients. Research nutrient supplementation to increase non-specific immunity, especially in Pacific white shrimp (Litopenaeus vannamei) still rarely done, especially with the addition of fish oil. This research was conducted to study the effect of fish oil supplementation in different oil among lemuru oil and patin oil with a non-specific parameter of Pacific white shrimp among total haemocyte count (THC), the differential haemocyte count (DHC), challenge test with Vibrio harveyi and relative percent survival (RPS). Design of experiments using a completely random design with three treatments and four replications. The treatment is adding  the lemuru oil (treatment A), patin oil (treatent B) and without the addition of fish oil (control). The results showed that the addition of lemuru fish and patin fish oil treatment can increase THC, DHC, which affect the phagocytic activity relative to the level of protection without giving fish oil (P<0.05). The increasing of non-specific immunity of Pacific white shrimp with fish oil needs to analyze in the economic  side to be more economical if applied to the shrimp farmers or commercial feed mills.
