The influence of administration of FOPFE (Fermented Oil Palm Fronds Extract) on digestibility and goat performance of Kacang goat is the aims of this study. The fermentation process of oil palm fronds is carried out by adding 10% poultry manure for 21 days with, then extracted with methanol solvent. Twelve male goats>1 year were used in this research, were placed in a metabolic caged which were equipped with feedbox and drink. Randomized block design, 4 treatments with 3 groups was used in this research namely : P0 = complete ration + 0% FOPFE; P1 = complete ration + 0.1% FOPFE; P2 = complete ration + 0.2% FOPFE and P3 = complete ration + 0.3% FOPFE. The measured parameters were digestibility of nutrient (organic matter, dry matter, crude fiber, crude protein, extract eter, ADF, NDF, hemicellulose and cellulose) and goat performance of kacang goats (body weight gain, intake of dry matter, body weight gain, conversion of feed and efficiency of ration). The results showed that FOPFE to 0.3% has no significant effect (P>0.05) on average daily gain, nutrient digestibility, feed conversion and feed efficiency but significantly effect (P<0.05) on goat performance. The administration of 0.3% of FOPFE can maintain nutrient digestibility and goat performance.
Aquaculture is growing rapidly in Banjar District of Kalimantan Selatan Province, including on Riam Kanan Reservoir which is a center for floating net cage aquaculture. The increasing aquaculture on Riam Kanan Reservoir is not supported by adequate and actual data regarding the distribution, number of plots and number of fishery household (FHs) of floating net cage aquaculture. Complete, accurate and actual data is needed as one of the considerations in implementing sustainable aquaculture management policies. This study aims to map the distribution of floating net cages based on zones and business scale level, analyze the number of plots and the number of FHs of floating net cage aquaculture on Riam Kanan Reservoir. The study was conducted in July-October 2019 using 2 survey methods: a drone survey to collect aerial photographs and a field survey to identify the number of FHs and floating net cage plots based on business scale level. The results of aerial photography were analyzed using the Agisoft Metashape Professional and Arcgis 10.7 applications. Field survey data were analyzed using the Archgis 10.7 application and Microsoft Excel. The floating net cage is spread over 6 zones totaling 4,263 plots, consisting of criteria for small business scale 1,774 plots, medium scale 1,234 plots and large scale 1,255 plots. FHs of floating net cage aquaculture spread in 7 villages as many as 425 units with the criteria of 331 small scale business, 87 medium scale and 28 large scale. The plots and FHs of floating net cage aquaculture on Riam Kanan Reservoir has increased significantly over the past 4 years.
Jawa Timur adalah salah satu propinsi di Indonesia yang memiliki potensi perikanan, di perairan Kenjerana Surabaya Jawa Timur jumlah nelayan dan armada perikanan yang harus dikelola dengan baik, salah satu unit penangkapan yang ada adalah jaring insang dasar, target ikan hasil tangkapan dari alat tangkap ini adalah jenis ikan kakap putih (Lates calcarifer). Dengan penambahan alat pemanggil ikan berbasis gelombang bunyi diharapkan dapat meningatkan hasil tangkapan. Penelitian ini membandingkan 2 perlakuan dan 16 kali ulangan dari penelitian ini didapatkan perbandingan jumlah hasil tangkapan jaring insang dasar tidak menggunakan alat bantu pemanggil ikan yaitu 31 ekor dan yang menggunakan alat pemanggil ikan 39 ekor ikan. Jenis hasil tangkapan jaring insang dasar yang tidak menggunakan alat bantu pemanggil ikan, jenis dan presentase jenis ikan yaitu kakap (Lates calcarifer) 12%. Laosan (Eleutheronema tetradactylum) 12%. Sumbal (Glossolepis incisus) 12%. Presentase menggunakan alat pemanggil ikan ada 6 jenis yaitu sotong (Mastigoteuthis flammea) 1%, rajungan (Portunas pelagicus) 1%, laosan (Eleutheronema tetradactylum) 11%, manyung (Ariidae) 3%, kakap putih (Lates calcalifer) 83%, bandeng (Chanos-chanos)1%, Kata kunci: Jaring Insang dasar, kakap putih, Alat pemanggil ikan berbasis gelombang bunyi.
