Abstract

The high demand for fish consumption, especially freshwater fish, make cultivator developing aquaculture especially intensive systems, but constrained by various problems. Such as environmental pollution and increased cases of diseases. Then the need for such a solution that is like biofloc cultivation system. The purpose of this research is to know the combination of optimal biofloc system treatment for Tilapia fish (Oreochromis sp.) FCR (Feed Conversion Ratio). The experimental design used in this study was factorial design, with three repetitions. Factor 1 (ratio C: N), which consists of 3 levels C: N: 12, 18, and 24; Factor 2 (concentration of probiotic bacteria), which consists of two levels of 106 and 108 CFU / ml. This study consisted of six treatments namely A1B1 (ratio C: N 12 + bacterium 106 cfu / ml); A1B2 (ratio C: N 12 + bacterium 108 cfu / ml); A2B1 (ratio C: N 18 + bacteria 106 cfu / ml); A2B2 (ratio C: N 18 + bacteria 108 cfu / ml); A3B1 (ratio C: N 24 + bacteria 106 cfu / ml); A3B2 (ratio C: N 24 + bacteria 108 cfu / ml). The parameter observed is the FCR. The results of this study is the highest FCR on the C / N treatment Ratio 24 and at the density of probiotic bacteria 108 CFU / ml that is equal to 1.69

Abstract

The aim of this research is to know the sanitation ascpect of Smoke Julung- julung fish processing (Sagela) in Pasalae Village, Gentuma Raya, Gorontalo Utara. This research was held ini Pasalae Village from August to December 2017. The type of research was used is a survey with respondents sample selected using random sampling technique, data collection by using questionnaires. Data analyzed by descriptive analysis. The result show that there are deviations on the sanitation dan hygiene conditions in smoke industry, which are five cricital deviation such as the layout, the employee hygiene, the prevent of cross contaminastion, the changing rooms, the shower dan toilet and pest control. For serious deviations is location and environment. Major deviation is waste handling. Two minor deviations are water security dan production equipments. From the description can concluded the smoke unit of sagela is not appropriate as a processing unit of fishery product in accordance with good standart

Abstract

Tujuan dari penelitian ini adalah menganalisis dan membuktikan kombinasi yang paling optimal probiotik pada pakan dengan padat tebar yang berbeda terhadap pertumbuhan mutlak dan kelulus hidupan pada benih ikan mujair (Oreochromismossambicus). Penelitian ini dilakukan di Laboratorium Akuakultur Universitas Muhammadiyah Gorontalo. Metode yang digunakan dalam penelitian ini adalah eksperimental dengan skala laboratorium. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL) faktorial. Dosis prebiotik pada pakan yaitu 15ml/kg (P1) dan 20ml/kg (P2) dengan 3 perlakuan padat tebar yaitu 2, 3, 4 ekor dan 3 kali ulangan. Tahapan dalam penelitian ini yaitu dari persiapan alat dan bahan, menyiapkan bakteri probiotik (Bacillus sp., Lactobacillus sp., Nitrosomonas sp.), pemberian probiotik pada pakan serta media, kemudian pemeliharaan beih ikan mujair (Oreochromis mossammbicus) selama 10 minggu. Variable yang diamati dalam penelitian ini adalah pertumbuhan berat mutlak dan kelulushidupan. Hasil yang diperoleh pertumbuhan tertinggi dicapai pada perlakuan P1B yaitu dengan rerata 12,74 g. Sedangkan pertumbuhan terendah dicapai pada perlakuan P2C yaitu dengan rata-rata sebesar 9,44 g.Kelulus hidupan tertinggi terdapat pada perlakuan (P1B) 93%, sedangkan kelulushidupan terendah pada perlakuan P2C yaitu sebesar 86,67 %.Kata Kunci: Potensi Probiotik, Mujair (Oreochromismossambicus), Pertumbuhan, Kelulushidupan, Pakan, Padat Tebar
