Abstract

Ikan sidat (Anguilla bicolor) merupakan jenis ikan yang memiliki pertumbuhan lambat karena daya cernanya yang rendah. Salah satu usaha yang dapat dilakukan untuk meningkatkan pencernaan pakan adalah dengan penambahan enzim eksogenus ke dalam pakan ikan sidat. Enzim eksogenus yang sering ditambahkan ke dalam pakan adalah enzim papain. Penambahan enzim papain pada pakan komersial diduga dapat mengoptimalkan pencernaan ikan sidat (A. bicolor) melalui aktivitas proteolitiknya. Tujuan dari penelitian ini adalah mengetahui pengaruh dan dosis terbaik penambahan enzim papain pada pakan komersial terhadap efisiensi pemanfaatan pakan, pertumbuhan dan kelulushidupan ikan sidat (A. bicolor). Ikan uji yang digunakan dalam penelitian ini adalah elver ikan sidat (A. bicolor) sebanyak 120 ekor dengan bobot rata – rata 6,05±1,17 g/ekor. Wadah pemeliharaan yang digunakan berupa akuarium dengan volume 70 liter sebanyak 12 buah. Penelitian dilakukan dengan metode eksperimental RAL dengan satu faktor yaitu dosis enzim papain berbeda yang diulang sebanyak tiga kali. Perlakuan yang digunakan adalah A (dosis enzim papain  0%/kg pakan), B (dosis enzim papain 0,85%/kg pakan), C (dosis enzim papain 1,70%/kg pakan), dan D (dosis enzim papain 3,40%/kg pakan). Hasil penelitian menunjukkan bahwa penambahan enzim papain pada pakan berpengaruh nyata terhadap EPP, PER, dan RGR (Sig.<0,05). Perlakuan penambahan dosis enzim papain terbaik adalah perlakuan D (dosis enzim papain 3,40%/kg pakan) yang menghasilkan nilai EPP sebesar 59,12±1,74%, PER sebesar 1,74±0,05%, dan RGR sebesar 1,59±0,10%/hari. Kualitas air pada media pemeliharaan terdapat pada kisaran yang layak untuk pemeliharaan ikan uji. Freshwater eel (Anguilla bicolor) is a type of fish that has slow growth due to low digestibility. One effort that can be done to improve the digestion of feed is by the addition of exogenous enzymes into the eel feed. Exogenous enzyme that are often added to the feed is papain enzymes. The addition of papain enzyme into commercial feed is expected to optimize freshwater eel’s digestion through its proteolytic activities. The purpose of this study is to know the effect and the best dose of papain enzyme addition into commercial feed on feed efficiency, growth rate and survival rate of freshwater eel (A. bicolor). The test fish used in this study is elver freshwater eel  as much as 120 fish with average weight 6,05±1,17 g/fish. As many as 120 aquariums with a volume of 70 liters is used as a culture container in this study. The study was conducted by experimental method of completely randomized design with one factor that is the different dose of papain enzyme which is repeated three times. The treatment used were A (dose of enzyme papain 0%/kg feed), B (dose of enzyme papain 0,85%/kg feed), C (dose of enzyme papain 1,70%/kg feed), and D (dose of enzyme papain 3,40%/kg feed). The study result showed that the addition enzyme papain in feed had significantly effect on EPP, PER and RGR (Sig.<0,05). The best treatment is treatment D (dose of papain enzyme 3,40%/kg feed) which is produce EPP values of 59,12±1,74%, PER of 1,74±0,05%, and RGR of 1,59±0,10%/day. Water quality in media is within a reasonable range for the culture of test fish.

Abstract

Peningkatan produksi ikan mas (Cyprinus carpio) akan berbanding lurus dengan kebutuhan pakan. Masalah yang sering dihadapi pembudidaya ikan mas adalah efisiensi pemanfaatan pakan yang belum maksimal dari pakan komersil dan hampir menghabiskan sekitar 60% dari total biaya produksi untuk pakan. Oleh karena itu, pakan yang diberikan harus efektif dan efisien agar dapat dimanfaatkan dengan baik oleh tubuh ikan mas untuk pertumbuhan. Efisiensi pemanfaatan pakan ikan mas dapat ditingkatkan dengan penambahan enzim eksogenus diantaranya enzim papain. Disisi lain, pemberian pakan dalam jumlah berlebih pada budidaya ikan mas dapat menyebabkan penurunan kualitas air yang berakibat terjadinya peningkatan kematian. Hal tersebut dapat diatasi dengan penambahan probiotik pada media pemeliharaan budidaya ikan mas. Penelitian ini bertujuan untuk mengetahui pengaruh kombinasi penambahan enzim papain pada pakan buatan dan probiotik pada media pemeliharaan terhadap efisiensi pemanfaatan pakan, pertumbuhan dan kelulushidupan ikan mas (C. carpio). Ikan uji yang digunakan adalah benih ikan mas dengan bobot rata-rata 3,21±0,23 g/ekor. Pemberian pakan yaitu pada pukul 08.00 dan 16.00 secara at satiation. Ikan uji dipelihara dengan padat tebar 1 ekor/l dengan lama pemeliharaan 42 hari.  Penelitian ini menggunakan metode eksperimental Rancangan Acak Lengkap (RAL) pola faktorial dengan 2 faktor dan 3 kali ulangan.  Perlakuan dalam penelitian ini adalah kombinasi penambahan enzim papain pada pakan dan probiotik media pemeliharaan dengan dosis yang berbeda yaitu: perlakuan A1B1 (enzim papain 0,25 g/kg pakan dan probiotik 1 mL/L); A1B2 (enzim papain 0,25 g/kg pakan dan probiotik 2 mL/L); A2B1 (enzim papain 0,5 g/kg pakan dan probiotik 1 mL/L); A2B2 (enzim papain 0,5 g/kg pakan dan probiotik 2 mL/L); A3B1 (enzim papain 0,75 g/kg pakan dan probiotik 1 mL/L) dan A3B2 (enzim papain 0,75 g/kg pakan dan probiotik 2 mL/L). Hasil penelitian menunjukkan bahwa penambahan enzim papain pada pakan buatan dan probiotik pada media pemeliharaan ada interaksi (P<0,05) terhadap efisiensi pemanfaatan pakan (EPP) dan laju pertumbuhan spesifik (SGR), tetapi tidak ada interaksi (P>0,05) terhadap kelulushidupan (SR). Perlakuan A3B1 (enzim papain 0,75 g/kg dan probiotik 1 mL/L) memberikan nilai tertinggi pada EPP dan SGR yaitu masing-masing sebesar 75,44±2,19% dan 2,19±0,03%/hari. Kualitas air pada media pemeliharaan terdapat pada kisaran yang layak untuk pemeliharaan ikan uji.  Kesimpulan dari hasil penelitian ini adalah kombinasi penambahan dosis enzim papain sebesar 0,75 g/kg pakan dan probiotik pada media pemeliharaan sebesar 1 mL/L merupakan dosis terbaik terhadap efisiensi pemanfaatan pakan dan pertumbuhan ikan mas (C. carpio). Increasing production of common carp (Cyprinus carpio) will be directly proportional to the feed needs. The problem which often faced by common carp farmer is the efficiency utilization of commercial feed that has not yet been maximum and nearly spent about 60% of the total production costs for feed. Therefore, the given feed must be effective and efficient in order to be utilized properly by the body of the common carp for growth. The efficient utilization of feed common carp can be improved by the addition of exsogenus enzyme which contain of papain enzymes. On the other hand, excess amounts of feeding on common carp cause a decreasing in water quality that can increase fish mortality. This can be overcome by the addition of probiotics on media of common carp. This present study was aimed to determine the effect combination of papain enzyme on artificial feed and probiotics in media on feed utilization efficiency, growth and survival rate of common carp (C. carpio). The experimental fish was common carp with the average body weight was 3,21 ±0,23g/fish.  The feeding frequency was twice a day, that was at 08.00 and 16.00, by applying at satiation method.  The fish was cultured with stocking density of 1 fish/l for 42 days.  This research was used an experimental method of completely randomize design complete randomized design factorial with 2 factors and 3 replicates.  The treatment in this study: treatment A1B1 (0,25 g/kg of papain enzyme in feed and 1 mL/L of probiotic), A1B2 (0,25 g/kg of papain enzyme in feed and 2 mL/L of probiotic), A2B1 (0,5 g/kg of papain enzyme in feed and 1 mL/L of probiotic), A2B2 (0,5 g/kg of papain enzyme in feed and 2 mL/L of probiotic), A3B1 (0,75 g/kg of papain enzyme in feed and 1 mL/L of probiotic), A3B2 (0,75 g/kg of papain enzyme in feed and 2 mL/L of probiotic). Data showed that the addition of papain enzyme in artificial feed and probiotics in the media make an interaction (P<0,05) on the feed utilization efficiency (FUE) and specific growth rate (SGR), but did not make an interaction (P>0,05) on the survival rate (SR). Treatment A3B1 (papain enzyme 0,75 g/kg feed and probiotic 1 mL/L) produced the high value for FUE and SGR that were 75.44±2.19% and 2,19±0,03%/day. Water quality parameters during the rearing period were suitable for the trial fish. The results showed that the optimum dosage for common carp (C. carpio) is 0,75 g/kg of papain enzyme in feed and 1 ml/l of probiotic in the media.

Abstract

Penggunaan bahan nabati sebagai sumber protein nabati dalam pakan memiliki kelemahan utama, seperti adanya asam fitat yang menyebabkan mineral-mineral penting dan protein dalam pakan tidak dapat diserap dengan baik oleh tubuh, sehingga efisiensi pemanfaatan pakan tidak maksimal. Penanggulangannya dilakukan dengan cara penambahan enzim eksogenus seperti enzim fitase ke dalam pakan buatan. Enzim fitase akan menghidrolisis asam fitat menjadi inositol dan asam fosfat, sehingga efisiensi pemanfaatan pakan, kecernaan dan penyerapan nutrisi menjadi maksimal. Tujuan dari penelitian ini adalah mengetahui pengaruh perbedaan dosis enzim fitase pada pakan buatan terhadap pertumbuhan, efisiensi pemanfaatan pakan dan kelulushidupan benih nila larasati (O. niloticus). Ikan uji yang digunakan adalah benih nila larasati (O. niloticus) dengan bobot rata-rata 0,72±0,05 g/ekor dan padat tebar 25 ekor/m3. Penelitian ini menggunakan metode eksperimental dengan Rancangan Acak Lengkap 4 perlakuan dan 3 kali ulangan. Perlakuan dalam penelitian adalah penambahan enzim fitase A (0 mg/kg pakan), B (400 mg/kg pakan), C (800 mg/kg pakan) dan D (1.200 mg/kg pakan). Hasil penelitian menunjukkan bahwa perlakuan D (1.200 mg/kg pakan) memberikan nilai RGR, EPP dan PER tertinggi yaitu 12,16±0,14% (RGR), 68,38±2,24% (EPP) dan 2,25±0,07 (PER). Kesimpulan yang didapat dari penelitian ini adalah pengaruh dosis fitase dalam pakan buatan memberikan pengaruh sangat nyata (P<0,01) terhadap RGR, EPP dan FCR dan berpengaruh nyata (P<0,05) terhadap PER, namun tidak berpengaruh nyata (P>0,05) terhadap SR. Dosis optimal yang dapat meningkatkan pertumbuhan, efisiensi pemanfaatan pakan dan rasio efisiensi protein adalah 1.200 mg/kg pakan yang mampu menghasilkan RGR sebesar 12,2%/hari, EPP sebesar 68,4% dan PER sebesar 2,25%. Kualitas air pada media pemeliharaan berada pada kisaran yang sesuai untuk budidaya ikan nila larasati. The use of plant material as a source of protein in artificial feed currently has major weakness, such as the presence of phytic acid that causesthe essential minerals and protein in the diet can not be absorbed by the body, so the efficiency of feed utilization was not optimal.Countermeasures is done by the addition of exogenous enzymes such as phytase enzyme into artificial feed.

Abstract

Udang vaname (Litopenaeus vannamei) adalah karnivora yang sukar mencerna protein nabati dalam pakan sehingga efisiensi pemanfaatan pakan belum maksimal.  Hampir 40-60% dari total biaya produksi hanya untuk biaya pakan. Efisiensi pemanfaatan pakan dapat ditingkatkan dengan penambahan enzim papain dalam pakan yang mampu meningkatkan penguraian dan pencernaan bahan pakan yang mengandung protein nabati sederhana sehingga dapat meningkatkan daya cerna protein pakan. Penelitian ini bertujuan mengkaji pengaruh suplementasi enzim papain dalam pakan terhadap efisiensi pemanfaatan pakan, performa pertumbuhan dan kelulushidupan udang vaname. Hewan uji berupa udang vaname dengan bobot rata-rata 3,02±0,21 g/ekor yang diperoleh dari pembudidaya udang vaname Desa Blebak, Kecamatan Mlonggo, Jepara.  Metode dalam penelitian ini adalah metode eksperimen, dengan Rancangan Acak Lengkap, 4 Perlakuan dan 3 kali pengulangan. Terdapat 4 perlakuan suplementasi enzim papain dalam pakan yaitu A (0 %), B (0,1 %), C (0,2 %), dan D (0,3 %). Parameter yang diamati meliputi EPP, PER, RGR, SR dan parameter kualitas air. Hasil penelitian menunjukkan bahwa penambahan enzim papain dalam pakan meningkatkan EPP, PER, RGR, namun tidak berpengaruh pada SR udang vaname. Enzim papain sebesar 0,1%/kg pakan merupakan dosis optimal pada EPP, PER dan RGR menghasilkan nilai maksimal sebesar 66,51%, 1,64 dan 4,22%/hari. White shrimp (Litopenaeus vannamei) is a carnivorous animal that difficult to digests vegetable protein in the feed so that the efficiency of feed utilization is not maximal. Nearly 40-60% of the total production cost is only for feed cost. Feed efficiency is improved by using papain in the feed which can increase the breakdown and consumption of feed containing vegetable protein so that it can easily increase the digestibility of feed protein. This study examines the effect of papain supplementation in feed on the growth performance, efficiency of feed utilization, and survival rate of white shrimps. The test animals were white shrimp with an average weight of 3.02 ± 0.21 g / individuals obtained from the whiteleg shrimp farmers in Blebak Village, Mlonggo District, Jepara. The method in this study was an experimental method, with a completely randomized design, 4 treatments, and 3 repetitions. There were 4 supplements of papain in feed: A (0%), B (0.1%), C (0.2%), and D (0.3%). The parameters were EPP, PER, RGR, SR, and water quality parameters. The results showed that the supplementation of the papain in feed increased the EPP, PER, RGR, but had no effect on the SR of white shrimp. Papain of 0.1% / kg of feed was the optimal dose at EPP, PER, and RGR resulting in a maximum value of 66.51%, 1.64 and 4.22% / day.

Abstract

The purpose of this research is to evaluate Asian sea bass digestibility and growth fed with phytase dietary supplementation on soybean based fish diet. The initial weight of fish was 4.99±0.2 g with stocking density of 20 fishes per tanks reared in 80 L tank of sea water for 6 weeks. Completely Randomized Design of 50% soybean meal with phytase supplementation of 0; 500; 1,000; and 1,500 FTU kg-1 and three replication was used in this trial. Chromium oxide (Cr2O3) was used as digestibility indicator. Multivariate anova and One way anova (SPSS); linear regression (Microsoft Excel) and polynomial orthogonal (Microsoft Excel and Maple) was used to analyze the data. The results of Multivariate anova showed that phytase supplementation affect total digestibility (KCT) and relative growth rate (RGR) of asian seabass significantly (P<0.01) with phytase dose 1,000 FTU. One way anova also indicated that phytase 1,000 FTU significantly affect all parameters. Apparent digestibility coefficient (ADC) phosphorus had a very significant and dominant effect to total digestibility with R2 = 0.9669 than ADC protein and ADC fat (linear regression). KCT significantly affects efficiency of dietary protein (EPP) 30.57% and protein efficiency ratio (PER) 0.67%. EPP and PER significantly effect RGR 1.56%  day-1, simultaneously. The optimal dose of phytase supplementation is 1,220 FTU.
