Authors: Saad Entsar A. , Habib Salem A. , Eltabeey Mona S.
Published: December 2017

Background: Lately, several studies have utilized non-invasive serological markers to assess liver fibrosis and some are currently being validated as potential tools to determine liver damage. Purpose: Our aim was to investigate the diagnostic performance of AFP, autotoxin and collagen IV as non-invasive biomarkers of hepatic fibrosis. Patients and methods: 45 males and 15 females with chronic hepatitis C were enrolled in the current study. Laboratory assessment was done for all subjects in form of complete blood picture, liver function test, alpha fetoprotein (AFP), collagen IV and autotaxin. Patients were grouped according to the stage of fibrosis into F1, F2 and F3. Results: Mean serum values of AFP, autotaxin and collagen IV were elevated in all patients compared to healthy controls. Surprisingly, with increasing fibrosis stage AFP showed non-significant change while collagen IV and autotoxin showed significant increase (P less than 0.01 and P less than 0.0001, respectively). Autotaxin and collagen IV were significantly (P less than 0.01 and P less than 0.05, respectively) lower in F1 patients than those with F2-F3 but AFP level showed non-significant change. Autotaxin had the highest area under ROC curve and the highest accuracy for discrimination of F1 from F2-F3 patients and for discrimination of patients with F3 from F1-F2. Different combinations between AFP, collagen IV and autotoxin showed improvement in the accuracy. Conclusion: It was concluded that serum autotaxin may at least serve as a new clinical non-invasive alternative in patients who are not candidates for liver biopsy for diagnosis of liver damage. Autotaxin combination with collagen IV and AFP addition make them more useful.

Java Message Service Based Performance Comparison of Apache ActiveMQ and Apache Apollo Brokers
Authors: Sarhan Qusay I. , Gawdan Idrees S.
Published: December 2017

Software integration is a crucial aspect of collaborative software applications and systems. It enables a number of different software applications, created by different developers, using different programming languages, and even located at different places to work with each other collaboratively to achieve common goals. Nowadays, a number of techniques are available to enable software integration. Messaging is the most prominent technique in this respect. In this paper, two leading open-source messaging brokers, Apache ActiveMQ and Apache Apollo, have been experimentally compared with each other with regard to their messaging capabilities (message sending and receiving throughputs). Both brokers support exchanging messages between heterogeneous and distributed software applications using several messaging mechanisms including Java Message Service (henceforth JMS). A number of experimental test scenarios have been conducted to obtain the comparison results that indicate the one-to-one JMS messaging performance of each broker. Overall performance evaluation and analysis showed that Apache Apollo outperformed Apache ActiveMQ in all test scenarios regarding message sending throughputs. Whereas, Apache ActiveMQ outperformed Apache Apollo in most test scenarios regarding message receiving throughputs. Moreover, the evaluation methodology (test conditions, test scenarios, and test metrics) proposed in this paper has been carefully chosen to be adopted by software developers to evaluate other messaging brokers to determine the acceptable level of messaging capabilities in distributed environments of heterogeneous software applications.

Published: December 2017

Equilibrium biosorption of mercury (II) onto new developed biosorbent (1,10-phenanthroline-graft- cell/Filamentous fungi) in both free, immobilized and dead cell were investigated. The product was characterized by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). In this work several isotherm models applied to predict the process design for the adsorption system. Hill, Sips, Langmuir and Freundlich utilized to determine the adsorption parameters, the equilibrium data fitted well to Hill and Sips isotherm models followed by Langmuir. Meanwhile, the maximum adsorption capacity proposed by Hill model was 78.67(mg/g) and Sips 78.42(mg/g) were lower than Langmuir models which was 85.16(mg/g). In other hand, the equilibrium data almost fitted to the Freundlich isotherm supporting the postulation of the heterogeneous shape of biosorption to certain range. Hence, On the bases of Langmuir model the biosorption of Hg2+ onto 1,10-phenanthroline-graft- cell/Filamentous was in the favourable area and that confirmed by calculating the separation factor (RL< 1). Nevertheless, new isotherm (Eq. 4) has been derived by the combination of a Langmuir and Freundlich models. The new model agreed well enough (R2 = 0.9863) with the experimental data.

Authors: Eesa Adel S. , Arabo Wahab Kh.
Published: December 2017

Neural Networks (NN) have been used by many researchers to solve problems in several domains including classification and pattern recognition, and Backpropagation (BP) which is one of the most well-known artificial neural network models. Constructing effective NN applications relies on some characteristics such as the network topology, learning parameter, and normalization approaches for the input and the output vectors. The Input and the output vectors for BP need to be normalized properly in order to achieve the best performance of the network. This paper applies several normalization methods on several UCI datasets and comparing between them to find the best normalization method that works better with BP. Norm, Decimal scaling, Mean-Man, Median-Mad, Min-Max, and Z-score normalization are considered in this study. The comparative study shows that the performance of Mean-Mad and Median-Mad is better than the all remaining methods. On the other hand, the worst result is produced with Norm method.

Authors: Eesa Adel S. , Abdulazeez Adnan M. , Orman Zeynep
Published: December 2017

Different Distributed Intrusion Detection Systems (DIDS) based on mobile agents have been proposed in recent years to protect computer systems from intruders. Since intrusion detection systems deal with a large amount of data, keeping the best quality of features is an important task in these systems. In this paper, a novel DIDS based on the combination of Cuttlefish Optimization Algorithm (CFA) and Decision Tree (DT) is proposed. The proposed system uses an agent called Rule and Feature Generator Agent (RFGA) to generate a subset of features with corresponding rules. RFGA agent uses CFA to search for optimal subset of features, while DT is used as a measurement on the selected features. The proposed model is tested on the KDD Cup 99 dataset. The obtained results show that the proposed system gives a better performance even with a small subset of 5 features when compared with using all 41 features.

Published: December 2017

A total of 300 eggs from 45 female quails from three different lines (Dark brown, light brown and white) aged 10 weeks old were equally divided into three experimental groups having 15 birds of each and caged separately, to estimate the external and internal egg quality traits. Half eggs were measured 24 hrs. post lay and others were measured after one week of storage at room temperature. The results showed that there were significant differences among lines for egg length, yolk height, yolk index, albumen diameter, albumen index and Haugh unit. The light brown line resulted in the best quality. All internal egg quality characters and egg length were differed significantly between fresh and storage eggs. The fresh eggs resulted in better quality than stored eggs. Phenotypic correlation appeared that there were significant correlation coefficients between some egg quality characteristics in dark brown line more than light brown and white lines.

Published: December 2017

Turkic languages are of the distinguished languages in the world by the vocabulary richness. In these languages, the words and terms related to almost all areas of life and household are found; and the borrowed words have been included in the lexical fund of the Turkish languages only in order to enrich the language and to increase its synonyms. However, there exist such words in our language, that they have been accepted as the product of any foreign language, or presented as a lexical unit belonging to only one language in the case of belonging to many languages of the world. These include the roots such as pa-, ter- _ der-, id- _ iz.
Reading in Space: An Exemplary Case of Continuity in the Contemporary Albanian Literature
Authors: Xhindi Ermir
Published: December 2017

The aim of our work was the discovery of a reading dimension in the contemporary Albanian literature, respectively in the Albanian post soc-realist prose, which is not merely a structural tool for the construction of the text and its meaning, but a condition for identifying the literary process in its continuity. We are based on the implications of the implementation of a hybrid Eco (Umberto) - Fish (Stanley) model as a time content in its core, in relation to the notion of intertextuality proposed by Julia Kristeva and used by us as reading in space, during the study on the process of overcoming socialist realism in the early 90s in the Albanian literature through the texts of Fatos Kongoli, an eminent Albanian author. The role of the traditional reading community has been proved as determinant for the sustainability of the process and the building of new structural and meaning equilibriums.
Fixed Word-Combination and Simple Word-Combination in the Terminology of Economy in Accordance with English Language
Authors: Pllana Sadete , Breznica Albulena Pllana
Published: December 2017

The problems of economic terminology can be handled from different angles. Today, there are many discussions about the concept of phrase terms and their reflection in the explanatory dictionaries of economic terms. Phrasal terms are reflected lexicographically in the terminology dictionaries but are also included in the explanatory dictionaries, collective lexicographic works and of the codifying and normative character of the Albanian language. The subjects break down the concepts in a transparent way, so today they have become one of the key tools for constructing terms in general. The widespread dissemination of fixed word-combination phrases in language as a specific lexical-syntax unit, especially in the terminology of the economy, creates a special layer in the terminology lexicon circle, which is characterized by specific features and attributes. Therefore, in this paper, we have been dealing with fixed and simple word-combination phrases, more widespread in the terminology of the economy, in accordance with the English language.

Authors: Bhusal Pramod , Dangol Rajendra
Published: December 2017

The main aim of the article is to find out the performance of different metrics proposed to CIE TC 1-91. Currently, six different indexes have been proposed to CIE TC 1-91: Colour Quality Scale (CQS), Feeling of Contrast Index (FCI), Memory colour rendering index (MCRI), Preference of skin (PS), Relative gamut area index (RGAI) and Illuminating Engineering society Method for evaluating light source colour rendition (IES TM-30). The evaluation and analysis are based on previously conducted experiment in lighting booth. The analysis showed the area based metric FCI was good subjective preference indicator. The subjective preference was measured in terms of naturalness of objects, colourfulness of colour checker chart, and the visual appearance of the lit scene in the booth.
Variations on a classical theme: On the formal relationship between magnitudes per square arcsecond and luminance
Authors: Bará Salvador
Published: December 2017

The formal link between magnitudes per square arcsecond and luminance is discussed in this paper. Directly related to the human visual system, luminance is defined in terms of the spectral radiance of the source, weighted by the CIE V(l) luminous efficiency function, and scaled by the 683 lm/W luminous efficacy constant. In consequence, any exact and spectrum-independent relationship between luminance and magnitudes per square arcsecond requires that the last ones be measured precisely in the CIE V(l) band. The luminance value corresponding to mVC=0 (zero-point of the CIE V(l) magnitude scale) depends on the reference source chosen for the definition of the magnitude system. Using absolute AB magnitudes, the zero point luminance of the CIE V(l) photometric band is 10.96 x 104 cd·m-2.

Authors: Kyba Christopher C. M. , Kuester Theres , Kuechly Helga U
Published: December 2017

Changes in the total lit area and the radiance of stably lit area in the German federal states from 2012-2016 were investigated using the Day-Night Band of the Visible Infrared Imaging Radiometer Suite. Most states increased in both lit area and radiance. The lit area of Bayern and Schleswig-Holstein grew rapidly, at annual rates of 9.7% and 8.8% respectively. Thüringen was dramatically different from the other states, with a 4.5% annual decrease in lit area, and a 17% annual decrease in the radiance of stably lit areas. In at least some cases, the increases in lighting in Bayern area associated with transitions to LEDs, which may not be indicative of a transition towards sustainable lighting. In addition to these results, this paper discusses the role of remotely sensed nighttime data within the context of sustainable lighting.

A mulher do espectador implícito: a audiência feminina nos primórdios da TV portuguesa
Authors: CARVALHEIRO José Ricardo
Published: December 2017

Este artigo é um subsídio para a história das ideias de audiência. Com base na imprensa da época, procura-se compreender qual a concepção de audiência feminina proposta nos discursos públicos durante a fase inicial da televisão portuguesa (de 1957 a meados dos anos 60). O contexto de ditadura e a cultura patriarcal vigente enquadram a construção ideológica da mulher como receptora subalterna, mais no papel de esposa e mãe do que de pessoa autónoma, e dão ao conjunto de espectadoras o caráter de nicho de audiência, mas não de público.

Esferas de visibilidade jornalísticas e relações de poder: um estudo sobre a memória do Oeste catarinense na imprensa nacional e regional (1940-1950)
Authors: BAVARESCO Marcionize Elis , LOCATELLI Carlos
Published: December 2017

Este trabalho analisa como a região Oeste de Santa Catarina, Brasil, foi retratada na imprensa regional e nacional a partir de dois fatos noticiosos ocorridos em 1948 e 1950. Ambas as coberturas (sobre o contrabando de madeira e sobre um linchamento) tratam de temas que colocam em confronto perspectivas de ordem, progresso, atraso e marginalidade. As esferas de visibilidade do jornalismo são aqui compreendidas no plural, com foco em duas delas: a do jornalismo de proximidade e aquela baseada no jornalismo de distanciamento. A base teórico-metodológica da pesquisa combina a análise documental, bibliográfica e de conteúdo. A principal conclusão do trabalho é que, nos casos analisados, o sistema jornalístico se configura em um imbricado jogo de escalas em que as relações de poder expressas nos discursos dos jornais são influenciadas pela proximidade e pelo distanciamento do seu público, suas fontes, seus financiadores e representantes políticos. É nesse cenário que a imprensa registra em suas páginas uma “batalha de memórias”, aqui observada em suas dimensões regional e nacional.
Grandes acontecimentos como aplicação estratégica dos discursos jornalísticos: a Batalha do Irany (1912) e o combate aos “germanófilos” (1917) nas páginas de O Progresso e do Diário dos Campos
Authors: PONTES Felipe Simão
Published: December 2017

Este artigo estuda os discursos sobre a Batalha do Irany (1912) e sobre os “germanófilos” ponta-grossenses na Primeira Guerra Mundial (1917), presentes no jornal O Progresso/Diário dos Campos. Utiliza-se a metodologia da análise arqueológica dos discursos proposta por Michel Foucault. Entendem-se esses discursos do jornal como estratégias que alinhavaram modos específicos de enunciação, constituição de objetos e conceitos com vistas a inserir a produção do jornal em relações de saber e poder. A pesquisa apresenta formas como o jornal projetava condutas e comportamentos como ideais, ao passo que marginalizava outras. O jornalismo praticado por O Progresso/Diário dos Campos colocou a serviço desses temas seu arsenal de destaque, formas para atrair a atenção dos leitores e demonstrar a importância do tema tratado. Os dois acontecimentos servem para se perceber como fatos externos ao cenário ponta-grossense reverberaram localmente na vida de pessoas e na utilização de espaços públicos.

Este trabalho parte de uma pesquisa historiográfica e documental sobre a produção da coluna social ao longo do século XX, desde sua origem, nos Estados Unidos, suas marcas históricas no Brasil e sua introdução no interior do Rio Grande do Sul, objetivando apresentar as mudanças ocorridas ao longo do período. Apresentamos as principais características e identificamos diferentes fases, efetuando uma periodização a partir das mudanças ocorridas. Apresentamos a divisão, de forma não linear, em quatro etapas: de 1920 a 1940; de 1940 a 1950; de 1960 a 1980; de 1990 ao século XXI. Realizamos a análise documental e bibliográfica considerando linguagem, fontes, temática e modificações que sofreu na sua forma de produção. Concluiu-se que os colunistas gaúchos foram influenciados por colunistas da grande imprensa dos anos 40, 50 e 60, mantendo o mesmo modelo até o final do século XX.
Uma perspectiva sobre a cidade de Porto Alegre a partir das crônicas de Jotabê no Correio do Povo (1955 – 1959)
Authors: GOLIN Cida , LINHARES Bruna
Published: December 2017

Este artigo discute a relação entre crônica, jornalismo e cidade a partir do estudo de textos publicados entre 1955 e 1959 pelo jornalista João Bergmann, o Jotabê, na coluna O domingo é meu, no jornal Correio do Povo, um dos principais veículos do estado do Rio Grande do Sul durante o século XX. O objetivo é entender quais elementos o autor utilizava para construir seu olhar sobre a cidade de Porto Alegre, por meio da análise qualitativa de seis crônicas consideradas representativas de tendências encontradas em um conjunto de 188 textos. A pesquisa sistematiza dados até então inéditos sobre a biografia e trajetória do cronista. Por meio do uso da análise de conteúdo, identificamos que Jotabê olhava a cidade sob o viés da mudança, resultado das intensas transformações urbanas vividas na década de 1950. Constatamos certo tom pessimista nos relatos, que evidenciam os conflitos cotidianos da urbe. Notamos o humor como importante marca expressiva, capaz de atenuar e dar leveza às críticas sistemáticas feitas pelo jornalista.

Determination of copper in sugarcane spirit by flame atomic absorption spectrometry using a ternary solvent mixture (water-ethanol-acetone)
Authors: De Souza João Carlos , Toci Aline Theodoro , Beluomini Maísa Azevedo , Eiras Sebastião De Paula
Published: December 2017

The present work describes the use of a homogeneous ternary mixture of the solvents water, ethanol, and acetone to improve the determination of copper in sugarcane spirit by flame atomic absorption spectrometry. The solvent ratio used (on a volume basis) was 5.0:5.0:15.0 (water:ethanol:acetone). The analytical curve for copper was linear up to a concentration of 6.00 mg L-1 of copper, and could be described by the equation: Δabs = 0.1778CCu + 0.0048 (r2 = 0.9999), and limits of detection and quantification (calculated using the standard deviation of the blank) were 0.01 and 0.05 mg L-1 of copper, respectively. Use of the proposed homogeneous ternary solvent system provided good stability and a significant increase in sensitivity compared to reference methodology. This increase in sensitivity enables the detection of smaller quantities of copper in sugarcane spirit. The method was applied to determine copper in commercial brands of sugarcane spirits. The results obtained by the proposed method were favorably compared with those given by the reference method.
Glass formation in the Sb2O3-SbPO4-WO3 system
Authors: Franco Douglas Faza , Fares Hassen , De Souza Antônio Eduardo , Santagneli Silvia Helena , Nalin Marcelo
Published: December 2017

Glasses in the ternary system (Sb2O3)(0.6-x)(SbPO4)(0.4)(WO3)(x), with composition 0.1 £ x £ 0.5 were studied. The structural changes due to the replacement of Sb2O3 by WO3 have been investigated. It was found that the incorporation of WO3 enhances the thermal stability of the glasses against devitrification when compared to the binary Sb2O3(0.6) - SbPO4(0.4) composition. The connectivity of the network increases with WO3 content which is consistent with the high values of the glass transition temperature. Raman studies suggest that WO3 incorporation breaks the primary network, constituted by antimony oxide, while a second network containing WO6 octahedral units is built up. Thermal and structural properties were evaluated by differential scanning calorimetry, infrared and Raman spectroscopies, 31P Magic Angle Spinning NMR and X-ray absorption near edge structure (XANES) at L1 and L3 edges of Sb and L1 edge of W atoms.

During sugar production, contamination of the sugar by potentially toxic metals may occur. Therefore, it is necessary to develop methods to quantify these contaminants. An analytical method for the monitoring of lead in sugar samples was developed with the use of homogeneous ternary system of solvents and UV-Vis spectrophotometry. The ternary system was optimized using multivariate experiments and the best condition was: 10% water, 80% ethanol and 10% methyl isobutyl ketone. As the complexing agent, monosodium 4- (2-pyridylazo) resorcinol was used. The calibration curve was linear from 0.64 to 5.0 mg.L-1, ABS = 0.0873 [Pb2 +] - 0.0032 and R² = 0.9988. The limit of quantification was 0.53 mg.L-1 and limit of detection was 0.45 mg.L-1 with 95% confidence level, the standard addition curve was linear, ABS = 0.0736 [Pb2+] + 0.0846 And R² = 0.9971. Three samples were analyzed in triplicate and the concentration of lead obtained ranged from 84,741 ± 3,700 mg.Kg-1; 69.926 ± 11.837 mg.Kg-1 and 76.444 ± 7.1111 mg.Kg-1. For the standard addition curve, the concentration found was approximately 230,000 mg.kg-1. Considering the Brazilian standard, the lead concentration should not exceed 2.00 mg.Kg-1, thus, it is concluded that the values obtained were not within the norm for this metal.

Funkcja retoryczna "Orgelbüchlein" Johanna Sebastiana Bacha. Wprowadzenie
Authors: Górny Tomasz
Published: December 2017

Na wstępie omówiono trzy podstawowe formy organizacji materii muzycznej, zastosowane w "Orgelbüchlein" Johanna Sebastiana Bacha: chorał melodyczny (najbardziej reprezentatywny i w związku z tym nazwany chorałem typu "Orgelbüchlein"), kolorowany oraz w kanonie (rozważono rolę Andreas Armsdorffa jako potencjalnego prekursora tego typu). Poświęcono również uwagę odstępstwom od tego schematu (przede wszystkim "In dir ist Freude" BWV 615) i podkreślono szczególną rolę partii pedałowej. W głównej części artykułu przedstawiono zagadnienie związków słowno-muzycznych w kontekście „Książeczki organowej”, rekapitulując pokrótce dawniejsze obserwacje z tego obszaru badawczego (Spitta, Schweitzer) oraz wpisując tę problematykę w szerokie pole badań nad relacjami retoryki oraz muzyki. I tak zwrócono uwagę na znaczenie teorii afektów oraz teorii muzycznych figur retorycznych. Ponadto przywołano koncepcję porównania sposobu układania oracji do procesu kompozycji – ten element retoryki muzycznej okazał się najmniej oczywisty w kontekście "Orgelbüchlein", niemniej myślenie o omawianych chorałach przez pryzmat inventio, dispositio oraz elocutio wydaje się możliwe. Wreszcie przypomniano kontekst tradycji luterańskiej, która nadała sztuce muzycznej bardzo wysoką rangę, zaś na koniec przeprowadzono krótką analizę chorału "Jesu, meine Freude" BWV 610 pod kątem retoryki muzycznej.

Keladi tikus (Typhonium flagelliforme) is one of considerable potential medicinal plants, especially as anticancer herbal medicine. In Indonesia, this plant grows throughout the island of Java, in part of Kalimantan, Sumatra and Papua. The development of Keladi tikus plants to provide raw material to meet public demand is constrained with the quality of the plants that is not standardized yet. DNA marker technique has been widely used for identification of standardization and diversity of varieties. The aims of this research were to isolate DNA from 17 accessions of Keladi tikus from various regions in Indonesia and to amplify the DNA using ISSR primers. The results obtained were 17 accessions of Keladi tikus that had been isolated using the modified CTAB method. Amplifications were done by using SBLT2 and SBLT8 primers that facilitated the appearance of the polymorphism bands on the 17 accessions of Keladi tikus. Thus, SBLT2 and SBLT8 primers can be used to identify genetic variations of Keladi Tikus.Keywords: Typonium flagelliforme, Keladi tikus, ISSR, medicinal plant, amplification ABSTRAKKeladi tikus (Typonium flagelliforme) merupakan salah satu tanaman obat yang cukup potensial khususnya sebagai obat herbal antikanker.

Bioethanol from oil palm trunk is one important source of energy to reduce greenhouse gas emissions and to avoid competition between the use for food and for energy as happens in other commodities. Pre-treatment of lignocellulosic biomass using sulfuric acid has high efficiency but requires high cost to neutralize the byproducts formed. Pre-treatment using hot compressed water and ball mill can be used to break down the structure and composition of lignocellulose so as to increase the rate of enzymatic hydrolysis and increase the sugar yield. Hydrolysis using an enzyme cocktail with hot compressed water and ball mill can each produce 210 mg of glucose at a temperature of 220°C and 200 mg of glucose for 120 minutes at room temperature per gram of oil palm trunk. Both of these processes are environmentally friendly and have a high efficiency in the production of bioethanol from oil palm trunks.Keywords: bioethanol, oil palm trunk, ball mill, hot compressed water, hydrolysis  ABSTRAKBioetanol dari batang kelapa sawit adalah salah satu sumber energi yang penting untuk mengurangi emisi rumah kaca dan menghindari konflik kepentingan antara kebutuhan bahan pangan dan penggunaan energi sebagaimana terjadi pada komoditas lain.

Existence of heavy metals in industrial waste is gaining global attention since their negative impact to environment. One of the efforts to solve the problem was to use plant to absorb metal in liquid medium, known as rhizofiltration. This research was aimed to select aquatic plants which showed relative resistantce and susceptibility to chromium. Four species of aquatic plants (Pistia stratiotes, Eichhornia crassipes, Lemna minor and Salvinia sp.) were grown in artificial medium (Hoagland) supplemented with 0, 1, 2, 4 and 8 ppm chromium. The plants resistance and absorption toward chromium was observed based on the morphology and chromium content in their biomass. Based on their resistance to and absorption of chromium, the selected plants were tested further in liquid waste of tanning industry. In Hoagland medium, Salvinia sp. demonstrated 67.2% higher resistance and absorption toward chromium while that of P. stratiotes 20.3% lower compared to other plants which were tested. This result could be applicable in reducing such environmental pollutant as the heavy metal chromium from industrial waste. Keywords: Phytoremediation, chromium, Hoagland medium, aquatic plants, liquid waste ABSTRAKLogam berat dalam limbah industri merupakan bahan pencemar lingkungan yang mendapatkan perhatian global. Salah satu upaya untuk mengatasi masalah tersebut adalah memanfaatkan tanaman untuk menyerap logam dalam medium cair atau dikenal sebagai fitoremediasi.

Dedak padi dan ampas kelapa dicampur dengan perbandingan tertentu dan kemudian difermentasi menggunakan Rhizopus oryzae untuk pakan ikan. Uji pemberian pakan lalu dilakukan untuk mengetahui pengaruh pakan terhadap pertumbuhan ikan mas (Cyprinus carpio L.). Dalam penelitian ini digunakan 5 perlakuan: satu perlakuan pakan tanpa fermentasi (pakan komersial 100%), dan empat perlakuan pakan fermentasi substrat campuran bekatul dan ampas kelapa dengan empat perbandingan yang berbeda, yakni 75%:25%, 50%:50%, 25%:75%, dan 0%:100%. Hasil penelitian menunjukkan bahwa pemberian pakan komersial 100% (protein sejati 15,25% dan serat kasar 6,27%) memperlihatkan hasil terbaik terhadap pertumbuhan ikan mas dengan pertambahan bobot badan 2,56 g dan rasio konversi pakan 1,95. Sementara itu pemberian pakan fermentasi (protein sejati berkisar 4,89-9,97% dan serat kasar 22,87-25,70%) hanya menghasilkan pertambahan bobot badan ikan pada kisaran 0,47-0,64 g dengan rasio konversi pakan 2,50-2,64. Dengan demikian pakan fermentasi tersebut mampu mendorong pertumbuhan ikan mas meskipun masih kurang optimal dibandingkan dengan pakan komersial.Kata Kunci: Rhizopus oryzae, Cyprinus carpio, rice bran, coconut bagasse, fermentation  ABSTRACTRice bran and coconut bagasse were mixed and then fermented using Rhizopus oryzae for preparing aquafeed. Subsequent feeding test was carried out to determine the effect on the growth of carps (Cyprinus carpio L). Five feeding treatments were employed, one unfermented feed (commercial feed 100%), and the other four feeds produced by fermentation using substrate mixture of rice bran and coconut pulp in four different ratios, namely 75%:25%, 50%:50%, 25%:75%, and 0%:100%. The results showed that feeding 100% commercial feed (true protein 15.25% and crude fibre 6.27%) showed the best results on the fish growth with body weight gain of 2.56 g and feed conversion ratio of 1.95. Meanwhile, feeding fermented feeds (true protein 4.89-9.97% and crude fiber 22.87-25.70%) only resulted in body weight gain in the range of 0.47 to 0.64 g with feed conversion ratio of 2.50 to 2.64. Thus, the fermented feeds promoted growth in tested carps albeit less optimally than commercial feed.Keywords: Rhizopus oryzae, Cyprinus carpio, dedak, ampas kelapa, fermentasi
