Abstract

Fungsi makanan bagi ikan adalah sebagai sumber energi yang diperlukan dalam proses fisiologi ikan. Oleh karena itu, makanan sebaiknya mengandung lemak dan komponen nutrisi lainnya. Lemak merupakan salah satu komponen makro nutrien yang memberikan kandungan energi terbesar dibandingkan dengan karbohidrat dan komponen lain. Lemak pakan mempunyai 2 fungsi utama, yaitu sebagai sumber energi metabolik dan sebagai sumber dari berbagai komponen asam lemaknya. Penelitian ini bertujuan untuk mengkaji minyak ikan dan lesitin dengan dosis berbeda dalam pakan terhadap pemanfaatan pakan dan pertumbuhan ikan mas (C. carpio).Metode penelitian yang dilakukan adalah metode eksperimen dengan rancangan acak lengkap (RAL) yang terdiri dari 4 perlakuan dan 3 kali ulangan.  Perlakuan yang diterapkan pada perlakuan A  menggunakan minyak ikan:lesitin sebanyak (0,0:0,0%), perlakuan B (0,30:0,0%), perlakuan C (0,60:0,30%), dan perlakuan D (0,90:0,60%). Hewan uji yang digunakan dalam penelitian adalah ikan mas (C. carpio) yang berasal dari Banjarnegara, dengan rerata bobot 1,62±0,23g dengan padat penebaran 1 ekor/1 liter air yang ditampung dalam toples plastik volume 8 liter, dengan masa pemeliharaan selama 35 hari. Sumber air yang digunakan pada penelitian ini adalah air tawar. Frekuensi pemberian pakan dilakukan sebanyak 3 kali sehari pada jam 08.00, 12.00, dan 14.00 WIB secara  at satiation. Hasil penelitian menunjukan bahwa pemberian minyak ikan dan lesitin ke dalam pakan buatan dengan dosis yang berbeda pada tiap perlakuan, memberikan pengaruh nyata (P<0,05) terhadap laju pertumbuhan relatif (RGR), efisiensi pemanfaatan pakan (EPP) dan protein efisiensi rasio (PER) pada ikan mas (C. carpio). Sedangkan pada variabel tingkat konsumsi pakan dan kelulushidupan tidak berpengaruh nyata (P>0,05). Perlakuan D merupakan hasil tertinggi dengan  nilai RGR (2.41 ±0.07%/hari), EPP (59.09±1.36%), PER (1.97±0.05%). Minyak ikan dan lesitin dengan dosis berbeda memberikan pengaruh yang nyata terhadap pemanfaatan pakan dan pertumbuhan ikan mas. The function of feed for fish as an energy source was required in the physiologycal processes. Therefore, the feed should contain fats, and other nutrients componds. Fat provide largest energy compared to carbohydrates for the similar weight. Fat in the diet have two main fuctions, that were as a metabolic energy and as a fatty acid sources. The aim of this research was to assess the role of fish oil and lecitine with different doses in the diet on the growth of carp. The method of the research used completely randomized design, which consisted of 4 treatments and 3  replicates. The experimental namely A, B, C, and D, that were animal and vegetable oil on trial diet as much as 0,0:0,0 ; 0,3:0,0 ; 0,60:0,30 ; and 0,90:0,60%), respectively. The trial fish was carp with the average body weigh of 1.62±0.23g. The fish was maintained in 8 L- plastic tanks for 35 days. The fish were fed, at satiation for 3 times a day, at 08.00, 12.00, and 16.00 local time. The data showed that the role of fish oil and lecitine with different doses and in the diet resulted on the significantly different (P<0,05) on the relative growth rate (RGR), feed utilization efficiency (EPP), and protein efficiency ratio (PER) of the carp. While for feed consumption rate (FCR) and survival rate (SR) were not significantly different (P>0,05). D treatment resulted on the highest RGR values (2.41±0.07%/days), EPP (5.09±1.36%), PER (1.97±0.05%). Values, fish oil and lecitine with different doses was able to increase on the growth of carp.

Hasil penelitian menunjukkan bahwa nilai fekunditas, HR, SR, FCR dan SGR menunjukkan bahwa perlakuan hibridisasi lebih baik dari perlakuan inbreeding dengan masing-masing nilai terbaik yaitu fekunditas pada perlakuan B (1479,00±120,58 butir telur), HR pada perlakuan B (73,61±2,71%), SR pada perlakuan C (74,68±3,99%), FCR pada perlakuan B (0,65±0,06), dan SGR pada perlakuan B (7,01±0,37 %/hari), tetapi pada nilai diameter dan bobot telur menunjukkan bahwa perlakuan inbreeding lebih baik dari perlakuan hibridisasi dengan masing-masing nilai terbaik yaitu diameter telur pada perlakuan A (2,79±0,23 mm) dan bobot telur pada perlakuan A (0,01±0,001 gram), Kualitas air pada media pemeliharaan terdapat pada kisaran yang layak untuk budidaya ikan nila. The objectives to know the character reproduction spawning tilapia Pandu (F6) (Oreochromis niloticus) with strains tilapia local red Kedung Ombo in hybridization and inbreeding covering fecundity, diameter and weights eggs, and hatching rate (HR) long and weight larvae egg yolk, long and weight larvae off egg yolk, survival rate (SR), feeds convertion ratio (FCR) and specific growth rate (SGR), and knowing the best treatment. Study was conducted from March-June 2015 in a work unit is Satuan Kerja Perbenihan dan Budidaya Ikan Air Tawar (PBIAT) Janti, Klaten. The  fish tilapia with weights on average ♂ ± 240-540 g and ♀ ± 110-260 g. This research was conducted with the experimental method using Random Design Complete (RAL) with 4 treatments and 3 repetition. The treatments in this study: the treatment A (Pandu (F6) ♂ x Pandu (F6) ♀), B (Pandu (F6) ♂ x Local Red Tilapia Kedung Ombo ♀), C (Local Red Tilapia Kedung Ombo ♂ x Pandu (F6) ♀), and D (Local Red Tilapia Kedung Ombo ♂ x Local Red Tilapia Kedung Ombo ♀). The observed data covering fecundity, HR, egg weight, diameter and length of the larval weights and egg yolks, the length and weight of the egg yolk off larvae, FCR, SGR, SR, and water quality. The research results show that the value of fecundity, HR, SR, FCR and SGR shows that treatment hybridization better than treatment inbreeding with each the best value that is fecundity in treatment B (1479.00±120.58 egg), HR in treatment B (73.61±2.71%), SR in treatment C (74.68±3.99%), FCR in treatment B (0.65±0.06), and SGR in treatment B (7.01±0.37%/day), but on the value diameter and weights eggs shows that treatment inbreeding better than treatment hybridization with each the best value that is diameter the eggs in treatment A (2.79±0.23 mm) and weights the eggs in treatment A (0.01±0.001 gram), the quality of water at media maintenance found in a range unfit for cultivation tilapia.

Abstract

Industri pengolahan ikan lele dapat menghasilkan produk hasil samping  (kepala lele) yang dapat dibuat tepung sebagai pengganti bahan baku protein utama dalam pakan.  Tepung kepala lele digunakan untuk menggantikan tepungikan dalam pembuatan pakan buatan untuk juvenil udang vaname  (Litopenaeus vannamei).  Penelitian ini dirancang untuk mengetahui pengaruh penggantian tepung ikan dengan tepung kepala lele dalam pakan terhadap efisiensi pemanfaatan pakan dan pertumbuhan juvenil udang vaname dalam skala laboratorium. Perlakuan yang diujikan adalah penggantian tepung ikan dengan tepung kepala lele sebesar 0% (A), 25% (B), 50% (C), 75% (D) dan 100% (E). Juvenil udang vaname  (2,47±0,07g) dipelihara dengan kepadatan 10 ekor perwadah (10 L) dan diberi pakan buatan tiga kali sehari pada pagi (07.00), siang (12.00) dan sore hari (17.00) secara ad libitum mengikuti kebutuhan jumlah pakannya. Juvenil udang vaname dipelihara selama 42 hari. Hasil penelitian menunjukkan bahwa tepung kepala lele mampu menggantikan tepung ikan hingga 50% dan tidak berpengaruh (P>0,05) terhadap efisiensi pemanfaatan pakan (25,59-29,64), protein efisiensi rasio (0,89-0,98) dan laju pertumbuhan spesifik (1,69-1,85%bobot/hari) juvenil udang vaname. Penggantian tepung ikan hingga 100% dengan tepung kepala lele tidak berpengaruh (P>0,05) terhadap kelulushidupan juvenil udang vaname. Penelitian ini membuktikan bahwa tepung kepala lele dapat menggantikan tepung ikan dalam ransum pakan buatan, sampai dengan penggantian 50% tanpa mempengaruhi efisiensi pemanfaatan pakan dan pertumbuhan juvenil udang vaname. Catfish processing industry can produce byproducts (catfish) which can be made of flour as a substitute for primary raw materials in feed protein. Flour catfish heads used to replace fish meal in the manufacture of artificial diets for juvenil shrimp vaname (Litopenaeus vannamei). This study was designed to determine the effect of flour replacement of fish meal with catfish heads in the feed efficiency of feed utilization and growth of juvenil shrimp vaname on a laboratory scale. The treatment being tested is the replacement of fish meal with catfish heads flour at 0% (A), 25% (B), 50% (C), 75% (D) and 100% (E). Vaname juvenil shrimp (2.47 ± 0.07 g) maintained at densities of 10 individuals per container (10 L) and artificial fed three times daily in the morning (07:00), lunch (12:00) and afternoon (17:00) ad libitum follow amount of feed needs. Vaname juvenil shrimp maintained for 42 days. The results showed that the flour could replace the head catfish up to 50% fish meal had no effect (P> 0.05) on feed utilization efficiency (25.59 to 29.64), protein efficiency ratio (0.89 to 0.98) and specific growth rate (1.69 to 1.85% / day) of juvenil shrimp vaname. Replacement of fish meal up to 100% with flour head catfish no effect (P> 0.05) on the survival of juvenil shrimp vaname. This study proves that the flour can replace the head catfish fish meal made in feed rations, up to the replacement of 50% without affecting the efficiency of feed utilization and growth of juvenile shrimp vaname.
