Abstract

ABSTRACTCatfish (Pangasius hypopthalmus) is one of the high economically freshwater fish. There are problems in catfish culture, especially related to the low of feed utilization. This could be solved by addition of protein and papain enzyme in feeds which play an important role on protein synthesis, so that it helps increasing the fish growth. The aim of the research was to analyze the effect of protein and papain enzyme in isocaloric feeds on the feed utilization efficiency and growth of catfish (P. hypopthalmus). The research was conducted in Mei to June 2018, at the Teaching Factory, Diponegoro University, Semarang. The body length of trial fish used ranged between 7 to 9 cm. The experimental method applied was factorial randomized design with two factors (order 2 x 2). Each factor consisted of two treatment levels with 3 replicates, so that, 12 experimental units were required. The first factor was feed with protein of 26% (A1) and 32% (A2), while the second factor was feed with the addition of papain enzyme as much as 0,25 g/kg feed (B1) and 0,50 g/kg feed (B2), respectively. Results showed that combination of protein and papain in an isocaloric feed had a significant effect on the total of feeding consumption level (TFC), feed utilization efficiency (FUE), and relative growth rate (RGR), but had no significant effect on the survival rate (SR). Results showed that the optimum dose of protein and papain in isocaloric feed was 32% of protein dan 0,25 g of papain/kg feed which was able to produced TFC of 154,32±4,52 g, FUE of 58,35±2,80%, and RGR of 4,66±0,06%/day.Keywords: Catfish, Protein, Papain Enzyme, Isocaloric Feed, Growth

Abstract

Oithona sp. merupakan salah satu zooplankton dari kelas crustacean atau udang-udangan yang memiliki kandungan protein dan kalsium yang lebih tinggi dibandingkan dengan artemia. Oithona sp. memiliki kandungan EPA (Eicosapentaeonic Acid) hampir sama dengan rotifer, tetapi kandungan DHA (Docosahexaenoic Acid) dalam Oithona jauh lebih besar dari rotifer. Kuantitas dan kualitas pakan merupakan faktor yang sangat penting untuk meningkatkan reproduksi dan pertumbuhan Oithona. Pakan yang sesuai akan menghasilkan performa pertumbuhan yang baik bagi Oithona. Kultur Oithona masih memerlukan pakan fitoplankton, namun dalam kultur fitoplankton membutuhkan waktu dan biaya yang relatif mahal. Pakan buatan yang diperkaya dengan tepung cacing tanah dapat diberikan untuk pakan O. similis karena Oithona termasuk jenis crustacea. Penelitian ini bertujuan untuk mengkaji pengaruh dan perlakuan terbaik pakan buatan yang diperkaya dengan tepung cacing tanah (Lumbricus rubellus) terhadap performa pertumbuhan Oithona similis.

Abstract

White Kakap (Lates calcalifer) is a superior commodity and has a high nutritional value. Growth factors are hampered by the ineffectiveness of the digestive process. Protease is an enzyme capable of hydrolyzing peptide bonds in proteins. Feed is a factor that predominantly affects the growth of fish because feed serves as a supplier of energy to support growth. Protein digestion in aquatic animals requires proteases as a catalyst. Enzymes that play an important role in the process of protein digestion are proteases. The purpose of this study is to examine the effect of adding different protease enzymes to artificial feed on the efficiency of protein utilization in the growth of white snapper (Lates calcalifer). The results of this study are expected to provide information about the importance of protease enzyme application in artificial feed in increasing protein hydrolysis, so that protein can be easily utilized by the body of white snapper (Lates calcalifer). The cultivars tested were white snapper (Lates calcalifer). The cultivation comes from intensively cultivated Lampung with an average weight of 6.5 ± 0.44 g / tail with a length ranging from 4-5 cm, as many as 75 heads. The research method is experimental laboratories using Completely Randomized Design (RAL). The tested feed was in the form of artificial feed with protein content of 40% and different protease dosage. The tested treatment was A feed (0.0% Protease enzyme from artificial feed weight), B (0.05% Protease enzyme from artificial feed weight), C (0.1% Protease enzyme from artificial feed weight), D (0 , 15% Protease enzyme from artificial feed weight), E (0.2% Protease enzyme from artificial feed weight). The ingredients of white snapper fish feed consist of fish meal, corn flour, soybean meal, shrimp flour, fish oil, corn oil, CMC / wheat flour, minerals and vitamins. Research data obtained for 40 days using analysis of variance (anova). If there is a real effect on the treatment then Duncan multiple area test is done. The result of this research indicated that the giving of protease 0,2% in artificial feed with protein 40% able to produce feed consumed Kakap Putih 43,43 ± 0,13 g, FCR 0,35 ± 0,002, Feed Pureness equal to 67,9 ± 1.23%, Protein Digestibility 98.25 ± 0.03%, Protein Retention 68.8 ± 0.23%, PER 7.97 ± 0.04, Fat Retention 0.6 ± 0.005%, E / P 4, 6 cal / g, thus giving effect on Specific Growth (SGR) 6.032 ± 0.17% and Length 8.3 ± 0.2 cm.

Abstract

Hatching rate of Artemia salina cysts in the hatching process is variable due to many factors. Osmolarity of the medium is one of the factors determining hatching process of A. salina cysts. The purpose of this study is to assess the hatching process of A. salina cysts in a various osmotic condition on the hatching energetics efficiency and rate. The experimental design used was a 2 x 5 factorial completely randomized design. The first factor is an addition of chlorine (non-decapsulation and decapsulation) and the second factor is osmolarity of medium (640.27; 787.02; 901.76; 1080.51 and 1227.25 mOsm.L-1H2O). The results showed that hatching of A. salina cyst on various osmotic condition has significantly differed the hatching rate. No significant differences in the hatching energetics efficiency were obtained from each experimental groups. Media with osmolarity level of iso-osmotic to hyperosmotic (901.76-1227,25 mOsm.L-1H2O) provides a high hatching rate. Energetics efficiency of artemia cysts hatching is ranged from 640.27 to 1227.25 mOsm.L-1H2O in both hypoosmotic, isosmotic and hyperosmotic media.
