PENGARUH WAKTU PENGUKUSAN YANG BERBEDA TERHADAP KUALITAS PRESTO IKAN SEPAT SIAM (TRICHOGASTER PECTORALIS)
Get PDFPresto is one the of the fish products processing by adding salt to the fish using high temperature and high pressure. The aim of this study was to know the effect of different steaming time on sepat siam (Trichogaster pectoralis) fish presto. The treatment used in this research is different steaming time (15, 30, 45 and 60 minutes) in the making of sepat siam fish presto. The result of this research showed that 45 minutes steaming time (treatment C) is the best treatment based on the organoleptic test in the specification ofthe texture and taste, but had no effect on the color and flavor specification and has no effect on chemical test for water content and protein (74.01% and 19.85%) respectively
KUALITAS LINGKUNGAN DAN AKTIVITAS ENZIM PENCERNAAN UDANG VANNAMEI (Litopenaeus vannamei) PADA BERBAGAI KONSENTRASI PROBIOTIK BIOREMEDIASI-Bacillus sp.
Get PDFBioremediation-Bacillus sp. probiotics with the composition of the beneficial bacteria, as well as working synergistically on aquaculture and environment in the host gastrointestinal tract. In addition, it can improve the quality of the environment can also increase the activity of digestive enzymes shrimp. Ultimately lead to increased growth and minimize the risk of disease of shrimp. The purpose of this study to determine the optimum concentration of applications Bioremediation-Bacillussp. probiotics vannamei shrimp culture in the media. The study was designed in a Completely Randomized Design (CRD) with 4 treatment concentration of bioremediation-Bacillus sp. probiotics the control (without probiotic), 0.5; 1.0, 1.5 ppmper week, with three replications each. During the study, the test shrimp rearing in glass aquaria with a capacity of 30 L with a density of 4 fish / L and fed the form of powder with 52% protein content as much as 70-100% of total biomass. Watermedium used ± 30 ppt salinity as much as 25 L. The results showed improvement of environmental quality cultivation occurs in the probiotic treatment applications, particularly ammonia levels lower than controls. Digestive enzyme levels of Į-amylase and protease also increased significantly compared to controls. This condition which cause the vannamei shrimp survival and growth were receiving higher than controls of probiotic treatment, while various concentrations of probiotic did not produce differences in response. Application of Bioremediation-Bacillus sp.probiotics can be concluded with a concentration of 0.5 ppm per week in culturemedia can improve the quality of the environment cultivation and the activity ofdigestive enzymes Į-amylase and protease, thus increasing the survival and growthof vannamei shrimp

Get PDFManajemen diperlukan karena sifat sumberdaya perikanan itu sendiri memiliki nilai yang tinggi dan peka terhadap pengelolaan dan terdapat 4 (empat) komponen dasar dalam manajemen yang harus dipertimbangkan, yaitu: (1) kelestarian sumberdaya; (2) sustainabilitas ekonomi; (3) sosial masyarakat (tenaga kerja); dan (4) lingkungan terutama habitat. Dalam pengelolaan sumberdaya perikanan yang berorientasi jangka panjang mengutamakan ke hati hatian dalam melakukan keputusan dan kebijakkan Pengelolaan perikanan bertujuan untuk memaksimalkan produksi tanpa merusak sumberdaya yang ada maupun lingkungan. Pengelolaan perikanan terdiri dari beberapa unsur yaitu (1) penilian sumberdaya, (2) pengambil keputusan, (3) pemilihan strategi, (4) alternatif manajemen (5) pengawasan. Sehingga seorang manager perlu adanya suatu penilaian mengenai risiko dan kerentanan dalam membahas peraturan, perlindungan sumberdaya perikanan dan habitatnya.Berdasarkan Kepmen KP No.6/2010 yang termasuk klasifikasi pukat tarik berkapal (Boat or vessel seine nets) yaitu cantrang dan dogol..

PENILAIAN STOK SUMBERDAYA IKAN GABUS (Channa Striata, Bloch 1793) Di KALIMANTAN SELATAN DENGAN PENDEKATAN MODEL HOLISTIK (Equilibrium - Non Equilibrium State)
Get PDFPenelitian ini bertujuan untuk memperoleh informasi ilmiah terkait penilaian stok (stock assessment) sumberdaya ikan ikan Gabus (Channa Striata, Bloch 1793) Di Kalimantan Selatan dengan Pendekatan Model Holistik (Equilibrium - Non Equilibrium State). Data yang digunakan dalam penelitian ini ialah data sekunder berupa data time series produksi dan upaya penangkapan ikan Channa Striata yang bersumber dari Dinas Kelautan dan Perikanan Provinsi Kalimantan Selatan. Estimasi hasil tangkapan lestari (MSY) ikan Channa striata dilakukan dengan menggunakan model produksi surplus melalui pendekatan equilibrium state model dari Schaefer (1954) dan Fox (1970) dan pendekatan non equilibrium state model dari model walter-hilborn (1976). Hasil penelitian model Schaefer (1954) menunjukkan bahwa status pemanfaatan tahun 2016 tergolong moderate exploited dengan Tingkat Pemanfaatan (TP) sebesar 74%. Status pemanfaatan berdasarkan model Fox (1970) pada tahun 2016 tergolong fully exploited dengan Tingkat Pemanfaatan (TP) sebesar 90%. Sedangkan status pemanfaatan berdasarkan model Walter-Hilborn (1976) pada tahun 2016 tergolong moderate exploited dengan Tingkat Pemanfaatan (TP) sebesar 62%. Potensi stok cadangan lestari sumberdaya ikan Channa Striata saat ini (Standing Stock) ialah 10.838 ton/tahun

In the transect line III found that Acropora digitate form of growth of 1.80%, 2.10% Non Acropora Branching, Massive abiotic 33.60% and 18.70%. Cover the condition of coral reefs showed that on the first transect lines (medium category) with a percentage of 47.52% coral cover transect line II(both categories) 53.96% and the line transect III (medium category) 37.50%
LAMA WAKTU PROSES CURRING TERHADAP PRODUK RAMBAK KULIT IKAN TENGGIRI (Scomberomorus commersonii)
No full textSkin of narrow - barred Spanish mackerel has not been maximally utilized. It is alternatively used as chips. It has good taste obtained from immersion the fish skin into herbs and spices. The objective of the study was to find the optimum time length of immersing the mackerel’s skin into the spices. This study is expected to be able toproduce the desired chip product, diversify the processed fish products, create newhousehold industry, and provide scientific information on environmental friendly wasteutilization. The ingredients needed in chip processing of the mackerel chips were garlic,tamarind, lime, coriander, salt, and ginger. While research method used is RAL with one factor of different time (4 treatment and 3 replication) and analysis of water content, testprotein and organoleptic level.Results showed that the lowest water content occurred in treatment A, 11.10 %,and the highest in treatment C, 13.26 %, while the lowest protein was found in treatmentA, 24.50 %, and the highest in treatment D, 61.25%. Water content was statisticallysignificantly different and protein content was highly significantly different amongtreatments. The organoleptic test found that the lowest mean value occurred in treatmentA, 5.046, and the highest in treatment B, 5.294. The sensory test gave significant effectonly on the taste. This difference indicates that the immersion time length of thetreatments could also impact on water content or protein content
