Abstract

Pemanfaatan protein dalam pakan merupakan salah satu masalah dalam kegiatan budidaya ikan nila hitam yang sangat erat kaitannya dengan pertumbuhan. Penambahan enzim papain pada pakan dilakukan untuk dapat memanfaatkan protein secara maksimal dan lebih optimal pada kultivan. Papain merupakan enzim protease  yang mampu menghidrolisis protein menjadi unsur-unsur yang lebih sederhana yaitu peptida hingga asam amino, sehingga meningkatkan pemanfaatan protein pakan oleh tubuh. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan enzim papain dalam pakan buatan serta dosis enzim papain yang optimal terhadap performa pertumbuhan benih ikan nila hitam (O. niloticus Bleeker). Ikan uji yang digunakan adalah benih nila hitam dengan bobot rata-rata 2,49±0,25 gr.ekor-1 dan padat tebar 1 ekor.L-1. Pemberian pakan 3 kali sehari pada pukul 08.00, 12.00, dan 16.00 secara at satiation. Penelitian dilakukan secara eksperimental menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 3 kali ulangan. Perlakuan A (0% papain), perlakuan B (1,125% papain), perlakuan C (2,25% papain) dan perlakuan D (3,375% papain). Variabel yang diamati adalah laju pertumbuhan relatif, protein efisiensi rasio, efisiensi pemanfaatan pakan, kelulushidupan dan kualitas air. Hasil penelitian menunjukkan bahwa  penambahan enzim papain dalam pakan buatan memberikan pengaruh yang nyata (P<0,05) terhadap peningkatan pertumbuhan relatif, protein efisiensi rasio, efisiensi pemanfaatan pakan dan tidak berpengaruh (P>0,05) terhadap kelulushidupan. Dosis papain: 2,38%, 2,34%, 2,33%, 2,72% mampu menghasilkan laju pertumbuhan relatif, protein efisiensi rasio, efisiensi pemanfaatan pakan dan net protein utilization optimal masing-masing sebesar 1,84%/hari, 2,38%, 71,6%, 0,804% untuk benih nila hitam. Kualitas air selama penelitian masih berada dalam kisaran yang layak untuk media budidaya ikan nila hitam. Utilization of protein in a feed is one of the problems in the black tilapia aquaculture that are closely related to the growth. The addition of the papain enzyme in the feed is used  to get a full advantage from protein maximally and more optimally for the kultivan. Papain is a protease enzyme that is able hydrolyze a proteins into simpler elements like peptides to amino acids, so it can be increase the utilization of protein in feed by the body. The purpose of this  research were to determine the effect of addition  papain enzyme in artificial feed and to determine the optimal dose of papain enzyme to growth performance of black tilapia seed (O. niloticus Bleeker). Test fish used black tilapia seed with weight approximately 2.49±0.25 g.fish-1 and stock density 1 fish. L-1. Feeding was done in 3 times a day at 08:00, 12:00, and 16:00 in at satiation method. The research used experimental method by completely randomized design (CRD) with 4 treatments and 3 replications. Treatment A (0% papain), treatment B (1.125% papain), treatment C (2.25% papain) and treatment D (3.375% papain). The observed variables were relative growth rate, protein efficiency ratio, efficiency of feed utilization, survival rate and water quality. The results showed that the addition of papain enzyme in artificial feed gave a significant effect (P<0.05) to increase the relative growth, protein efficiency ratio, feed utilization efficiency and had no effect (P>0.05) on survival rate. The dose of papain which was obtained is: 2.38%, 2.34%, 2.33%, 2.72% capable to produce relative growth rate, efficiency ratio, efficiency feed utilization and net protein utilization optimal 1.84%/day, 2.38%, 71,6%, 0,804% for the black tilapia. Water quality during the research is still in a decent range for a medium black tilapia fish aquaculture.

Hasil penelitian menunjukkan bahwa pemberian  jenis pakan yang berbeda memberikan pengaruh (P<0.05) terhadap RGRW, RGRL, EPP, dan PER, namun tidak berpengaruh (P>0.05) terhadap SR.  Nilai tertinggi untuk RGRW, RGRL, EPP, PER, dan SR sebesar 3.48%/hari, 1.40%/hari, 17.78%, 0.28%, dan 72.44%.  Kualitas air yang didapatkan selama penelitian masih dalam kisaran normal untuk kehidupan larva gurami. Berdasarkan hasil penelitian ini, disimpulkan bahwa perlakuan pemberian pakan terbaik untuk larva gurami adalah cacing sutera.  Gouramy (gouramy, Lac) is omnivorous freshwater fish, and highly economical value. Silk worm widely used as life food of gouramy larvae. However, it’s availability could be interrupted by of the weather.  Artemia sp. can be used as life food for gouramy larvae, too Artemia sp. can be used in the form of frozen and preserved. This research was aimed to study the utilization rate of frozen Artemia sp.,and silk worm on the growth and survival rate of gouramy larvae. The eksperimenal fish used was gouramy larvae with the average body weight of 0,02 grams, the stocking density of the fish was 300 fish/l. The feeding applied was at satiation, with the feeding frequency of 3 times a day, that was at 08.00; 12.00 and 16.00 WIB. The eksperimental method used was completely randomized design (CRD) with 3 treatments and 3 replicates. The trial feeds was A (frozen Artemia sp.), B (Preserved Artemia sp.) and C (silk worm), respectively. Variables measured included relative growth rate to weight and length, feed efficiency utilization, protein efficiency ratio and survival rate. The result of reseach was that different type of life food (P<0.05) had effect on RGRW, RGRL, EPP, and PER, but no significant (P>0.05) for SR. The highest value for RGRW, RGRL, EPP, PER and SR were 3.48%/day, 1.40%/day, 17.78%, 0.28%, and 72.44%, respectively. Water quality obtained during the reseach was within the normal range for gouramy life. Based on the study, It was concluded that the best feeding trial for gouramy larvae was silk worms.

Abstract

Di Indonesia ikan lele merupakan salah satu ikan konsumsi yang paling popular dan banyak dibudidayakan. Desa Sidoharjo merupakan bagian dari wilayah Kecamatan Pati Kabupaten Pati Provinsi Jawa Tengah mempunyai potensi budidaya air tawar yang menjanjikan. Pembudidaya ikan di Desa Sidoharjo memelihara ikan lele dengan system alami (tradisional) baik secara monokultur maupun polikultur. Namun permasalahan yang akan dibahas dalam  penelitian usaha budidaya ikan lele ini adalah tentang bagaimana upaya untuk memperoleh hasil yang baik dan menguntungkan dalam memenuhi keinginan masyarakat tetapi dengan mengeluarkan biaya seminimal mungkin karena hal tersebut mempengaruhi profit abilitas dari pendapatan para pembudidaya lele tersebut. Untuk memperbaiki profit secara financial perlu dilakukan perhitungan aspek finansial yang berkaitan seperti keuangan, permodalan, pembiayaan, pendapatan dan pendapatan dalam periode waktu tertentu. Variabel yang akan diamati dalam usaha budidaya lele adalah bibit, pakan, tenaga kerja, listrik, transportasi, perawatan aset, perizinan, pupuk dan obat-obatan. Sedangkan prospek bisnis dalam usaha dapat ditentukan berdasarkan perhitungan Payback Periode (PP), Net Present Value (NPV), Internal Rate of Return (IRR), Benefit Cost Ratio (B/C Rasio).  Berdasarkan variable tersebut dapat diambil kesimpulan apakah kegiatan budidaya ikan lele di Kecamatan Pati Kabupaten Pati layak atau tidak diusahakan lebih lanjut. Metode penelitian yang digunakan adalah metode deskriptif yang bersifat studi kasus dengan pengumpulan data yang menggunakan metode observasi langsung, wawancara dan distribusi kuisioner. Hasil penelitian ditinjau dari aspek ekonomi berupa rata – rata biaya investasi sebesar Rp. 185.580.000,-., biaya operasional sebesar Rp. 215.118.000, dan pendapatan sebesar Rp. 204.800.000,-. Berdasarkan hasil dari penelitian ini, disimpulkan bahwa usaha budidaya ikan lele di Kecamatan Pati Kabupaten Pati dikatakan layak untuk dijalankan dengan nilai NPV Rp. 223.869.427,- , tidak menghasilkan IRR, B/C Ratio 1 dan Payback Periode 2. In Indonesia, catfish is one of the most popular fish consumption and widely cultivated.Sidoharjo Village is part of Rowosari Sub-district, Kendal Regency, Central Java Province has a potential of freshwater cultivation that  promising.Fish farmers in Sidoharjo Village raise catfish with natural (traditional) system either monoculture or polyculture.But the problem that will be discussed in this catfish farming business study is about efforts to obtain good and profitableresults  in meeting the desires of people but by spending as little as possible because it affects the profitability of the income of the catfish farmers. It is necessary to calculate the related financial aspects such as finance, capital, financing, income and income within a certain period of time to improve profit financially.The variables to be observed in the cultivation of catfish are seeds, feed, labor, electricity, transportation, asset maintenance, licensing, fertilizer and medicine.Business prospects in this cultivation  can be determined based on Payback Period (PP), Net Present Value (NPV), Internal Rate of Return (IRR), Benefit Cost Ratio (B / C Ratio) calculations.Based on these variables can be concluded whether the catfish farming activities in District Rowosari Kendal District worthy or not further cultivated.

Abstract

The raising of needs of this fish followed by the increasing in quality of tilapia larval has resulted three hybrid tilapia fish strains. The differences in starins could change the nutritional requirement of those new strains. Because of that, appropriate commercial food was needed in order to maximize its growth. The aim of this experiment was to study the effects of tilapia (Oreochromis niloticus) strains on the response to the growth, survival rate and food conversion ratio on strains of tilapia seeds which was fed with 10,96 Kcal/gram protein foods. The purpose of this study was to give significant information about applying high quality tilapia fish strains and appropriate food in cultivating tilapia fish. The method used was completely randomized design with three treatments and four replicates, where the A treatment was Larasati strain fed on dietary E/P 10.96 kkcal/g protein; B treatment was the Red strain fed on dietary E/P 10.96 kkcal/g protein; and C treatment was the Black strain fed on dietary E/P 10.96 kkcal/g protein. The material used was 3 strains of tilapia which is Larasati, the Red and the Black. The result of the research showed that different strains of tilapia was significant effect to weight gain and long, but is not effect to efficiency feed utilization but and survival rate (P>0,05). The highest weight growth was found on Larasati strain which was (28,70±0,51%/day) of average weight growth, while the highest length growth was on Black strain which was (1,29±0,05%/day). The result rate was efficiency feed utilization (0.712±0.01% - 0.665±0,05%). The result for survival rate was (90,45±1,05 - 89,45±0,34). It was suggested The Effect of Differences F5-Tilapia Strain (Larasati, Red, Black) Fed on Dietary E/P 10,96 kcal/g Protein on its Growth and Survivors was able to significant effect RGRW and RGRLvalue.
