Freshwater culture commodity such as sangkuriang catfish (Clarias sp.) has high sufficient demand. One way to fullfil necessity of sangkuriang catfis demand is accelerate the growth. The aim of this research is to determine the present effect of different probiotics on commercial feed towards growth and feed efficiency of sangkuriang catfish. The research using experimental method, using Completely Randomized Design (CRD). Sangkuriang catfish kept in 30 days with four treatments and five replications, that is P1 (control), P2 (5% probiotics A), P3 (5% probiotics B), and P4 (5% probiotics C). The obtained data were processed by Analysis of Variance (ANOVA) and followed by Duncan Multiple Range Test if there was significant data. The result showed that different probiotics giving significant effect to growth rate and feed efficiency (p<0,05). The best sangkuriang catfish (Clarias sp.) growth rate is P2 treatment 2,88% ± 0,38, and the lowest is P1 treatment at 1,73% ± 0,7. The best feed efficiency is P2 treatment at 54,69% ± 9,67 and the lowest is P1 treatment at 30,27% ± 12,65
ABSTRAKMaggot merupakan organisme yang berasal dari telur black soldier yang mengalami metamorfosis pada fase kedua setelah fase telur dan sebelum fase pupa yang kemudian berubah menjadi lalat dewasa. sebagai pakan ikan maggot memiliki dua fungsi yaitu sebagai salah satu sumber protein yang dapat mensubtitusi tepung ikan dan sebagai pellet altematif yaitu maggot dapat langsung diubah menjadi pellet. Istilah "maggot" mulai dikenal pada pertengahan tahun 2005. Maggot dapat tumbuh pada bahan organik yang membusuk di wilayah temperate dan tropis. Tujuan dari penelitian ini adalah untuk menentukan kombinasi media ampas tahu dan kotoran ayam yang baik terhadap produksi maggot. Sedangkan untuk manfaat dari penelitian ini adalah untuk mengetahui persentase ampas tahu dan kotoran ayam terbaik terhadap jumlah produksi maggot. Serta sebagai sumber informasi untuk para petani ikan dalam melakukan budidaya maggot sebagai pakan alternatif. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan 3 ulangan. Adapun perlakuan yang diterapkan adalah sebagai berikut: Perlakuan A. ampas tahu 100%; B. ampas tahu 50% kotoran ayam 50%; Perlakuan C. ampas tahu 75% kotoran ayam 25%; Perlakuan D. ampas tahu 25% kotoran ayam 75%. Hasil penelitian kombinasi media ampas tahu dan kotoran ayam berdasarakan hasil Analisis Varian (ANAVA) menunjukan bahwa kombinasi media pada perlakuan B ampas tahu 50% kotoran ayam 50%, menghasilkan rata-rata produksi maggot terbaik yaitu 76,60 gram, sedangkan hasil uji lanjut dengan uji jarak berganda Duncan multipel range test menunjukan adanya perbedaan yang sangat nyata terhadap berat produksi maggot antar kombinasi yang digunakan dalam penelitian. Kandungan nutrisi maggot tebaik terdapat pada perlakuan B dengan protein kasar 34,34%, air 4,51%, abu 25,65 %, dan lemak kasar 3,54 %. Kata Kunci : maggot, ampas tahu, kotoran ayam, produksi ABSTRACT Maggot is an organism derived from eggs black soldier who experienced a metamorphosis in the second phase after phase before the egg and pupa which then turns into adult flies. as fish feed maggot has two functions: as a source of protein that can be substituted for fish meal and as an alternative pellets that maggot can be directly converted into pellets. The term "maggot" became known in mid-2005 Maggot can grow on decaying organic matter in temperate and tropical regions. The purpose of this study was to determine the combination of media tofu and feses chicken was good against maggot production. As for the benefits of this research was to determine the percentage of tofu and feses chicken is the best of the amount of production maggot. As well as resources for fish farmers in doing maggot farming as an alternative feed. This study uses a completely randomized design (RAL) with 4 treatments three replications. The treatment used is as follows: Treatment A: tofu 100%, B: tofu 50% feses chicken 50%, Treatment C: tofu 75% feses chicken 25%, Treatment D: tofu 25% feses chicken 75% ,. The results of the study media combinations tofu and feses chicken on the terms of the results of variant analysis (ANOVA) showed that the combination of media in treatment B tofu and feses chicken 50% to 50%, resulting in an average production of maggot best is 76.60 grams, while the results of a further test with Duncan's multiple range test multiple range test showed that there was a very real difference to the weight of maggot production between the combination used in the study. The content of nutrients contained in the best maggot treatment B with 34.34% crude protein, water 4.51%, ash 25.65% and 3.54% crude lipid. Keywords: maggot, tofu, feses chicken, production
AbstrakUdang vaname (Litopenaeus vannamei) merupakan suatu komoditas yang memiliki nilai ekonomis penting di Indonesia. Dari tahun ke tahun permintaan udang vaname akan terus meningkat. Salah satu cara untuk memenuhi kebutuhan permintaan udang vaname adalah peningkatan produksi dengan mempercepat pertumbuhan ikan. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh pemberian probiotik komersial pada pakan terhadap pertumbuhan dan efisiensi pakan udang vaname.Penelitian ini menggunakan metode eksperimental, yakni dengan Rancangan Acak Lengkap (RAL). Udang vaname dipelihara selama 35 hari dengan sepuluh perlakuan dan tiga ulangan. Data yang diperoleh diolah menggunakan Analysis of Variance (ANOVA) dan dilanjutkan Uji Berjarak Duncan bila didapatkan hasil yang berbeda nyata.Hasil dari penelitian menunjukkan bahwa pemberian probiotik pada pakan menghasilkan laju pertumbuhan dan efisiensi pakan yang berbeda nyata (p<0,05). Pertumbuhan udang vaname (Litopenaeus Vannamei) yang terbaik terdapat pada perlakuan P9 sebesar 1,41 ± 0,08. Efisiensi pakan tertinggi terdapat pada perlakuan P9 sebesar 48,80 ± 1,23. AbstractWhite shrimp (Litopenaeus vannamei) is one commodity that has an important economic value in Indonesia. From year to year white shrimp demand will continue to increase. One way to fullfil the necessity of white vaname demand is increasing production by accelerating the growth of fish. The aim of this research was to determine the effect of commercial probiotic on feed towards growth and feed efficiency white shrimp.This research used experimental method, using a Completely Randomized Design (CRD). White shrimp maintained for 35 days with ten treatments and three replications. The obtained data were processed using Analysis of Variance (ANOVA) and followed by Duncan Multiple Range Test if there was significant data.Results of the research showed that the probiotics in feed resulted in growth rate and feed efficiency were significantly different (p<0.05). Growth white shrimp (Litopenaeus vannamei) the best there is at P9 treatment of 1.41 ± 0.08. Feed efficiency is highest on P9 treatment of 48.80 ± 1.23.
