Potensi Jamur Tiram Putih (Pleurotus Ostreatus) Dalam Pengembangan Produk Burger Prebiotik Rasa Daging Panggang

The purpose of this research was to determine the level of consumer preferences of prebiotic burger with white oyster mushroom (Pleurotus ostreatus) and chicken. The research was carried out by experiment with seven treatments, that were the combination of white oyster mushroom (J) and chicken (A) ; JA1 (0:4), JA2 (1:3), JA3 (2:2), JA4 (3:1), JA5 (4:0), the control JA6 (beef 100%), and control JA7 (commercial chicken burger). Sensory analysis of this research used hedonic test and descriptive test. The results of cluster analysis (AHC) from hedonic test and analysis of Principal Component Analysis (PCA) from descriptive test were analyzed used preference mapping. The best treatment in this research was JA2 (oyster mushroom 1:3 chicken) with the level of consumer preference by 57% that have characteristic garlic flavor, garlic taste, barbeque flavor, barbeque taste, and chicken taste

Pengaruh Arus Terhadap Sebaran Sedimen Tersuspensi Di Muara Sungai Silugonggo Kabupaten Pati

Sedimen tersuspensi adalah material organik maupun anorganik yang melayang di dalam kolom air sebelum mengalami pengendapan ke dasar perairan. Sedimen tersuspensi dapat memicu pencemaran akibatnya yaitu terjadinya kekeruhan di perairan tersebut. Arus sebagai salah satu parameter hidro-oseanografi memiliki peran aktif terhadap sebaran sedimen tersuspensi. Arus mengakibatkan sedimen yang telah mengalami pengendapan kembali terangkat ke kolom perairan akibat dari proses turbulensi. Hal ini mengakibatkan konsentrasi sedimen tersuspensi meningkat. Penelitian ini bertujuan untuk mengetahui nilai konsentrasi sedimen tersuspensi dan pola sebaran konsentrasi sedimen tersuspensi yang dipengaruhi oleh arus yang terjadi di Muara Sungai Silugonggo Kabupaten Pati. Metode penelitian yang digunakan merupakan metode kuantitatif karena data penelitian berupa angka dan analisa menggunakan statistik atau model. Hasil penelitian menunjukkan nilai konsentrasi sedimen tersuspensi di Muara Sungai Silugonggo ketika menuju pasang pada kedalaman 0.2d antara 0.008-0.201 g/ml, 0.6d antara 0.016- 0.151 g/ml, dan 0.8d antara 0.033-0.637 g/ml. Nilai konsentrasi sedimen tersuspensi ketika menuju surut pada kedalaman 0.2d antara 0.016-0.125 g/ml, 0.6d antara 0.025- 0.145 g/ml, dan 0.8d antara 0.041- 0.174 g/ml. Hasil pengamatan arus menunjukkan arah arus dominan menuju barat laut. Kesimpulan dari penelitian ini yaitu kecepatan dan arah arus yang terjadi mempengaruhi pola sebaran sedimen tersuspensi di Muara Sungai Silugonggo, Kabupaten Pati

Studi Sebaran Sedimen Dasar Di Perairan Sumuradem, Kabupaten Indramayu

Perairan Sumuradem merupakan wilayah pengelolaan dari PLTU Sumuradem, Kabupaten Indramayu. Tujuan dari penelitian ini untuk mengetahui jenis sedimen dasar dan mengetahui hubungan antara pola sedimen dasar dengan arus laut di Perairan Sumuradem. Penelitian ini menggunakan metode deskriptif dan analisa pola arus dengan model matematik dan distribusi ukuran butir sedimen menggunakan Spatial Analyst pada ArcGIS. Sedimen dasar yang terdapat pada Perairan Sumuradem didominasi dari jenis sedimen pasir dan pasir lanauan. Simulasi pola arus dilakukan pada 4 kondisi dengan menggunakan software SMS 8.1 modul ADCIRC. Perairan Sumuradem memiliki bilangan Formzahl (F) sebesar 1.26 sehingga tergolong pasang surut tipe campuran condong harian ganda. Hasil Pengolahan software world current 1.03 menunjukkan jenis arus yang mendominasi Perairan Indramayu adalah arus pasang-surut dengan persentase sebesar 60.21 %. Hasil simulasi arah arus dominan mengarah ke barat daya dan timur laut dengan arus maksimum sebesar 0.088 m/s. Pola sebaran di Perairan Sumuradem jenis pasir berada disekitar muara dan daratan sedangkan untuk pasir lanauan tersebar di lepas pantai

Bis(2-amino-6-methyl­pyridinium) trans-diaqua­bis­(pyrazine-2,3-dicarboxyl­ato)cobaltate(II) octa­hydrate

The title compound, (C6H9N2)2[Co(C6H2N2O4)2(H2O)2]·8H2O, was obtained by the reaction of CoCl2·6H2O with 1,4-pyrazine-2,3-dicarb­oxy­lic acid and 2-amino-6-methyl­pyridine in aqueous solution (molar ratio 1:2:2). The CoII ion is situated on an inversion centre and is coordinated by two O and two N atoms of two symmetry-related 1,4-pyrazine-2,3-dicarboxyl­ate ligands and two water mol­ecules and has a disorted octa­hedral coordination environment. The asymmetric unit also contains four water mol­ecules. In the crystal, extensive inter­molecular classical N—H⋯O, O—H⋯O and O—H⋯N hydrogen bonds and π–π stacking inter­actions [centroid–centroid distance = 3.490 (1) Å] connect the various components, forming a three-dimensional network

Di-μ-hydroxido-bis­[aqua­(pyridine-2,6-dicarboxyl­ato)iron(III)] monohydrate

In the dinuclear title complex, [Fe2(OH)2(C7H3NO4)2(H2O)2]·H2O, the two Fe atoms are separated by 3.063 (1) Å. Inter­molecular O—H⋯O hydrogen bonds form an extensive three-dimensional hydrogen-bonding network, which consolidates the crystal packing

Liquidity Crisis, Granularity of the Order Book and Price Fluctuations

We introduce a microscopic model for the dynamics of the order book to study how the lack of liquidity influences price fluctuations. We use the average density of the stored orders (granularity $g$) as a proxy for liquidity. This leads to a Price Impact Surface which depends on both volume $\omega$ and $g$. The dependence on the volume (averaged over the granularity) of the Price Impact Surface is found to be a concave power law function $_g\sim\omega^\delta$ with $\delta\approx 0.59$. Instead the dependence on the granularity is $\phi(\omega,g|\omega)\sim g^\alpha$ with $\alpha\approx-1$, showing a divergence of price fluctuations in the limit $g\to 0$. Moreover, even in intermediate situations of finite liquidity, this effect can be very large and it is a natural candidate for understanding the origin of large price fluctuations.Comment: 18 pages, 7 figure

Self-adaptive combination of global tabu search and local search for nonlinear equations

Solving systems of nonlinear equations is a very important task since the problems emerge mostly through the mathematical modeling of real problems that arise naturally in many branches of engineering and in the physical sciences. The problem can be naturally reformulated as a global optimization problem. In this paper, we show that a self-adaptive combination of a metaheuristic with a classical local search method is able to converge to some difficult problems that are not solved by Newton-type methodsFundação para a Ciência e a Tecnologia (FCT
