Abstract

Ikan hias merupakan salah satu komoditi yang banyak diminati karena mempunyai daya tarik tersendiri baik warna, bentuk  maupun tingkah lakunya yang unik. Komet (Carassius auratus auratus) pertama kali dibudidayakan oleh masyarakat Cina pada tahun 1729. Namun pembudidaya sering menghadapi permasalahan adanya kecendrungan penurunan persentase daya tetas telur, mortalitas larva ikan yang tinggi serta warna ikan. Untuk itu maka harus dilakukan perbaikan genetik pada ikan budidaya dengan berbagai metode. Salah satunya dengan metode manipulasi kromosom, yaitu dengan cara pemberian teknik kejutan suhu panas. Sehingga penelitian ini bertujuan untuk mengetahui berapa kejutan suhu panas yang tepat pada daya tetas telur (hatching rate) dan kelangsungan hidup (survival rate) larva ikan komet( Carrasius auratus auratus ). Penelitrian ini dilaksanakan selama 2 bulan dari bulan Februari – April 2018 yang berlokasi di Balai Benih Ikan Kelobak Kepahiang, dengan alat berupa akuarium heater, blower dan bahan induk ikan komet matang gonad. Menggunakan Rancangan Acak Kelompok (RAK) dengan 4 kelompok dan 4 ulangan. K1 = Suhu 36oC, K2 = Suhu 38oC, K3 = Suhu 40oC, K4 = Suhu 42oC dan dilanjutkan dengan uji BNT. Variabel yang diamati adalah : (1) Waktu penetasan (2) Daya tetas telur (3) Kelangsungan hidup larva dan (4) Kualitas air

Abstract

This research was conducted from May to July 2020 at the Laboratory of the Faculty of Agriculture, Prof. Dr. Hazairin, SH Bengkulu for 50 days. The purpose of this study was to determine the stocking density of Tilapia (Oreochromis niloticus) on the growth of Tilapia cultivated in plastic containers using a basic filter. The design used was a completely randomized design (CRD), which consisted of 4 experiments and 4 replications in order to obtain 16 experimental units, namely P1 (stocking density 40 fish / m2), P2 (stocking density 50 fish / m2), P3 (stocking density 60 fish / m2), P4 (stocking density 70 fish / m2) with a size of 8 -12 cm. The results showed that stocking density had an effect on growth in absolute length and absolute weight but had no effect on feed conversion, feed efficiency and survival. The best density is in the stocking density of 60 individuals / m2 with a survival rate of 92.0%. By using a basic filter during the research, you can maintain water quality where dissolved oxygen in the water at the beginning of the maintenance of dissolved oxygen is 6.4 (ppm) - 6.8 (ppm) to 6.0 (ppm) - 6.8 (ppm), temperature ranges from 25 oC - 29 oC, and pH ranges from 6.8 – 7.

Abstract

ABSTRACTCurrently, supply of sludge worm (Tubifex sp.) merely came from wild, so that it could not meet demand for fish hatchery. Additionally, harvest from the wild did not have a quality assurance, due to the possibility of sludge worm becoming an agent of disease. This study was conducted to evaluate the production of sludge worm culture by utilizing catfish culture waste (Clarias sp. ) in bioflok system. In this system, water from catfish culture media flowed into sludge worm culture media using recirculation systems. This study used a completely randomized design with four treatments and two replications, in which treatment A (addition of catfish culture waste from intensive system), treatment B (addition of catfish culture waste from biofloc system), treatment C (the addition of fermented chicken manure at the beginning of experiment as negative control), and treatment D (addition of fermented chicken manure at the beginning of experiment and then every five days as positive control). The results showed that the highest production was obtained by treatment B at biomass growth of 0.97 kg/m2 and sludge worm density of 388.000 individu/m2. Keywords: sludge worm, biofloc, chicken manure, catfish, catfish culture waste  ABSTRAK Saat ini pasokan cacing sutra (Tubifex sp.) hanya berasal dari alam, sehingga belum mencukupi permintaan untuk kegiatan pembenihan ikan. Selain itu, hasil tangkapan dari alam tidak memiliki jaminan kualitas, karena cacing sutra dapat menjadi agen penyakit. Penelitian ini dilakukan untuk mengevaluasi hasil produksi budidaya cacing sutra dengan memanfaatkan limbah budidaya ikan lele (Clarias sp.) sistem bioflok. Pada sistem ini, air dari media budidaya ikan lele dialirkan ke media pemeliharaan cacing sutra menggunakan sistem resirkulasi. Penelitian ini menggunakan rancangan acak lengkap dengan empat perlakuan dan dua ulangan, yaitu perlakuan A (pemberian limbah ikan lele sistem intensif), perlakuan B (pemberian limbah ikan lele sistem bioflok), perlakuan C (penambahan fermentasi kotoran ayam pada awal penelitian sebagai kontrol negatif), serta perlakuan D (penambahan fermentasi kotoran ayam pada awal penelitian yang dilanjutkan setiap lima hari sekali sebagai kontrol positif). Hasil penelitian menunjukkan bahwa produksi cacing sutra tertinggi diperoleh pada perlakuan B dengan pertumbuhan bobot sebesar 0,97 kg/m2 dan kepadatan cacing sutra sebesar 388.000 individu/m2. Kata kunci : cacing sutra, bioflok, kotoran ayam, ikan lele, limbah budidaya ikan lele

Abstract

Peningkatan padat tebar pada budidaya ikan menyebabkan tingginya pengunaan pakan sehingga daya saing akan pemanfatan oksigen akan meningkat, ikan akan kekurangan oksigen sehingga pertumbuhan menjadi lambat. Daya saing pemanfatan oksigen terjadi karena banyaknya sisa-sisa feses yang menyebabkan terjadinya penumpukan amoiak yang akan diuraikan oleh bakteri dan mikroba lainnya. Dengan adanya sistem resirkulasi budidaya menggunakan kepadatan tinggi dapat dilakukan, ikan akan hidup sesuai dengan kebutuhan oksigen yang berasal dari proses difusi dari pergerakan air dan kotoran pun akan berkurang dengan penggunaan filter. Penelitian bertujuan untuk mengetahui padat tebar ikan nila (Oreochromis niloticus) yang terbaik terhadap pertumbuhan dan kelangsungan hidup ikan nila yang dibudidayakan di dalam kolam terpal dengan sistem Resirkulasi. Penelitian menggunakan Rancangan Acak Lengkap (RAL) yaitu 5 perlakuan dan 3 ulangan sehingga mendapatkan 15 unit percobaan ; P1 Padat tebar = 20 ekor/m2, P2 = 30 ekor/m2,P3 = 40 ekor/m2, P4 = 50 ekor/m2, P5 = 60 ekor/m2 dan dilanjutkan dengan Uji Polinomial Orthogonal. Hasil penelitian menunjukkan bahwa padat tebar yang berbeda berpengaruh sangat nyata (**) terhadap pertumbuhan panjang dan berat serta juga berpengaruh nyata terhadap konversi dan efesiensi pakan tetapi berbeda nyata (ns) terhadap kelangsungan hidup ikan nila (Oreochromis niloticus). Berdasarkan uji lanjut polynomial pada pengamatan berat biomassa ikan maka padat tebar yang terbaik untuk pemeliharaan ikan nila dengan sistem resirkulasi adalah 56 ekor/m2

The purpose of this study was to determine the best stocking density for silk worms (Tubifex sp.) Against the addition of silk worms with a recirculation system. This research was conducted for 60 days starting in December 2019 until January 2020 at Jl. Bumi Ayu 8. Rt. 27 Rw. 06, Bumi Ayu Village, Selebar District, Bengkulu City. The container used is a container made of wood with a length of 100 cm, a width of 50 cm meters and a height of 15 cm as many as 16 pieces, the materials used are worm seeds, POC chicken manure, mud and soil. The design used was a completely randomized design (CRD) with 4 treatments and 4 replications so that 16 treatment units were obtained, namely: (P1) 20 gram / m2 stocking density (P2): 25 gram / m2 stocking density (P3): 30 gram stocking density / m2 (P4): stocking density of 35 grams / m2. To determine the effect of stocking density treatment on the addition of the number of individuals and the western biomass, analysis of variance was carried out at the 5% and 1% levels. Meanwhile, to determine the best stocking density, a further test of the least significant difference (LSD) was carried out at the 5% and 1% levels. The parameters observed during the study were (1) the increase in the number of individual silkworms (Tubifex sp) and (2) the total weight of silkworm biomass (Tubifex sp.) And TSS (Total Suspended Solid). The results showed that different stocking densities with the recirculation system had a very significant effect on the addition of the number of individuals, the weight gain of biomass and had a significant effect on the utilization of TSS value by silkworms (Tubifex sp) and the best increase in the number of individuals was found in stocking density (30 grams / container) with an average addition of 61,372 individuals / container and an average biomass weight of 150.074 grams / container and the best utilization of TSS values ??by silk worms (Tubifex sp.) is stocking density (30 grams / container) with an average mean TSS value 1.612 mg / L.
