Abstract

The slow growth of the Java barb (Puntius javanicus Bleeker, 1855) fingerlings is due to the feeding of plant-based protein which is usually lack of lysine.  The lack of it, can hinder the feed efficiency and growth. The best way to solve the problem is by adding lysine in the diet. The objectives of the study were to determine optimal needs of lysine to increase feed efficiency, growth, and nutrient contents of Java barb.  The fish samples were fingerlings of Java barb which weighed from 3.26 to 3.78 g-1 fish. The feed comprised 30% isoprotein and 262 Kcal isoenergy supplemented with lysine amino acid.  The dosages of the lysine in the diet were 1.25% (A1), 1.5% (A2), 1.75% (A3), 2.0% (A4), 2.25% (A5), and 2.5% (A6) of dried diets. The parameters observed were relative growth rate (RGR), apparent digestibility coefficients of protein (ADCp), efficiency of feed usage (EFU), feed conversion ratio (FCR), protein efficiency ratio (PER), survival rate (SR), hepatosomalic index (HSI), viscerosomatic index (VSI) and nutrient contents of Java barb. The results of the study disclosed that the enrichment of lysine into the diet increased the feed utilization, the growth and the nutrient contents of Java barb.  The needs of lysine for Java Barb (Puntius javanicus) fingerlings to optimize feed efficiency, growth, and nutrition contents ranged from 1.58% to-1.70% dried diet (5.3 to 5.6 % of protein diet).

Abstract

AbstrakIkan baung (Hemibagrus nemurus) merupakan salah satu ikan air tawar yang memiliki nilai ekonomis penting. Permasalahan pada budidaya ikan baung yaitu laju pertumbuhan yang lambat diduga karena ikan baung kurang dapat memanfaatkan pakan secara efisien. Salah satu solusi untuk mengatasi permasalahan tersebut adalah dengan suplementasi Saccharomyces cerevisiae) pada pakan buatan komersial. Penelitian ini bertujuan untuk mengkaji pengaruh suplementasi S.cerevisiae dalam pakan buatan komersial terhadap efisiensi pemanfaatan pakan, pertumbuhan dan kelulushidupan benih ikan baung (H. nemurus). Benih ikan baung yang digunakan memiliki bobot rata-rata 1,76±0,03g/ekor. Penelitian ini menggunakan metode eksperimen dengan rancangan acak lengkap (RAL) terdiri atas 4 perlakuan dan 3 kali ulangan. Perlakuan dalam penelitian ini adalah suplementasi  S.cerevisiae pada pakan buatan komersial yaitu 0g/kg pakan (A); 2,5g/kg pakan (B); 5g/kg pakan (C); dan 7,5g/kg pakan (D). Hasil penelitian menunjukkan bahwa suplementasi  S.cerevisiae pada pakan buatan komersial berpengaruh nyata (P<0,05) terhadap kecernaan protein (ADCp), efisiensi pemanfaatan pakan (EPP), rasio konversi pakan (FCR), protein efisiensi rasio (PER) dan laju pertumbuhan relatif (RGR), tetapi tidak berpengaruh nyata (P>0,05) terhadap tingkat konsumsi pakan (TKP) dan kelulushidupan benih ikan baung. Perlakuan B (dosis S.cerevisiae2,5g/kg pakan) merupakan dosis terbaik yang memberikan nilai tertinggi pada ADCp (75,35%), EPP (76,24%), FCR (1,34), PER (3,85) dan RGR (3,79%/hari). Kesimpulan dari penelitian ini menunjukan bahwa suplementasi S.cerevisiae pada pakan komersial memebrikan pengaruh nyata pada ebebrapa parameter biologis ikan baung, dengan perlakuan B sebagai model perlakuan yang terbaik.Kata kunci : Saccharomycescerevisiae, kecernaan, pakan, pertumbuhanAbtractAsian redtail catfish (Hemibagrus nemurus) is one of the freshwater fish that has important economic value. The problem with Asian redtail catfish fish farming is the slow growth rate, presumably because Asian redtail catfish are less able to utilize feed efficiently. One solution to overcome this problem is by supplementing Saccharomyces cerevisiae in commercially feed. This study was conducted to examine the effect of supplementation of S. cerevisiae in commercially feed on the efficiency of feed utilization on growth performance and survival of Asian redtail catfish (H. nemurus) fingerlings. Asian redtail catfish  fingerlings used had an average weight of 1.76±0.03g/fish. This study used an experimental method with analysis of variance (one-way ANOVA) consisting of 4 treatments and 3 replications. Fish were fed with four dosages of supplementation with S. cerevisiae on feed, at 0 g/kg feed (A); 2.5 g/kg feed (B); 5g /kg feed (C); and 7.5g /kg feed (D). The results showed that S. cerevisiae supplementation in commercially feed had a significant effects (P<0.05) on protein digestibility (ADCp), feed utilization efficiency (EPP), feed conversion ratio (FCR), protein efficiency ratio (PER) and relative growth rate (RGR), but had no significant effects (P>0.05) on the level of total feed consumption (TKP) and survival of Asian redtail catfish fingerlings. Treatment B (S. cerevisiae 2.5g/kg feed) was the best dosage which gave the highest value for ADCp (75.35%), EPP (76.24%), FCR (1.34), PER (3.85 ) and RGR (3.79%/day).The conclusion of this study showed that supplementation of S. cerevisiae in commercial feed had a significant effect on several biological parameters of baung fish, with B treatment as the best treatment model.Keywords : Saccharomyces cerevisiae, digestibility, feed, growth

Abstract

Beong are one of endogenous fish in Indonesia and still rely on catches from nature. The level of growth and survival rate in culture of beong is still low, so it is necessary to do cultivation efforts for conservation of beong, so that the beong can be cultivated intensively. One effort that can be do is biological manipulation in the form of stocking density. This study aims to determine the effect of shocking density on growth and survival rate and find out the best amount too. The study was conducted in April-May 2018 at UPT BBI Sawangan, Magelang, Central Java. The method used in this study was experiment method and Completely Randomized Design (CRD) for 4 treatments, 3 replicates with stocking dencities of A (10 fish/m2), B (30 fish/m2), C (50 fish/m2)and D (70 fish/m2). The results showed that different stocking densities gave a significant effect (Sig.> 0.05) on TKP, FCR, SGR and SR. This is allegedly due to feed competition, space competition and cannibalism in Beong fish. Treatment B gave the best results at TKP, FCR, SGR and SR with a value of 1.36 ± 0.01 gr / individual, 1.15 ± 0.11, 4.58 ± 0.22% / day and 83.33 ± 3,34%.

Abstract

ABSTRAK Ikan guppy (P. reticulata) merupakan salah satu ikan hias air tawar yang banyak diminati karena variasi warna dan corak siripnya yang beragam. Warna ikan hias dipengaruhi oleh sel pigmen pada tubuh. Pigmen tersebut dihasilkan dari penambahan karotenoid pada pakan. Salah satu bahan penghasil karotenoid adalah tepung bunga marigold. Penelitian ini bertujuan untuk mengkaji pengaruh dan mengetahui dosis terbaik tepung bunga marigold dalam pakan buatan terhadap peningkatan kecerahan warna ikan guppy. Variabel yang diamati antara lain bobot mutlak, rasio konversi pakan, laju pertumbuhan spesifik dan kelulushidupan. Ikan guppy dengan bobot 0,19 ± 0,03 g diperoleh dari pembudidaya ikan hias guppy Sleman, Yogyakarta. Penelitian dilaksanakan di Galaksi Akuatik Indonesia, Semarang pada bulan Desember 2018-Januari 2019. Penelitian ini menggunakan metode eksperimen dengan rancangan acak lengkap (RAL) yang terdiri dari 4 perlakuan dan 3 kali ulangan. Perlakuan yang diterapkan adalah penambahan tepung bunga marigold dalam pakan buatan dengan dosis A (0 mg/kg), B (25 mg/kg), C (50 mg/kg) dan D (75 mg/kg). Hasil penelitian ini menunjukkan bahwa tepung bunga marigold berpengaruh nyata (P<0,05) terhadap tingkat kecerahan warna ikan guppy, namun tidak berpengaruh nyata (P>0,05) terhadap bobot mutlak, rasio konversi pakan (FCR), laju pertumbuhan spesifik (SGR) dan kelulushidupan (SR). Perlakuan C (50 mg/kg) memberikan nilai tertinggi pada peningkatan kecerahan warna ikan guppy (P. reticulata) yaitu 4,05. Kesimpulan yang diperoleh adalah dosis tepung bunga marigold 50 mg/kg memberikan hasil tertinggi pada kecerahan warna ikan guppy (P. reticulata).                                                                                                                                                                                                Kata Kunci :  Guppy; Marigold; Pakan; Kecerahan Warna. ABSTRACT    Guppy (P. reticulata) is one of the freshwater fish that has various colour with many type of fin pattern.
