Abstract Aquatic resources that have great potential to be developed is a pigment obtained from seaweed. According Winarno (1996), seaweeds are clasified into three classes, namely red algae (Rhodophyceae), brown algae (Phaeophyceae) and green algae (Chlorophyceae). There are three main types of pigment in the seaweed, namely: chlorophyll, carotenoids, and phycocyanin (Lila, 2004). Each type of pigment that provides different benefits to human life. Red seaweed spicifera types Acanthophora be extracted and taken the pigment has a branch color (thallus) are varied, due to the pigment composition consisting of chlorophyll a, chlorophyll d, and fikobiliprotein (R-phycocyanin, allofikosianin and fikoeritrin) (Lee, 2008) . Fikoeritrin is the dominant pigment in red algae, thus giving the appearance of red on the thallus. The use of pigments is very important not only in the food and beverages, but also in medicines, cosmetics and pharmaceutical industrial. It is one of the determinants of consumer acceptance of products offered. Source of pigments used are also used by consumers as one of the indicators in assessing the quality of a product. The use of natural or synthetic dyes in the product will enhance the visual appeal that will increase consumer preference for products offered, therefore, the use of natural dye for industrial cannot be avoided. Based on the description above, this study will extract the pigment from red algae (A.spicifera) with a polar solvent (ethanol, distilled water) which will be used as a dye in catfish sausage with different proportions and determine the color stability during storage at cold temperatures and using the analytical method for determining the wavelength spectrophotometer fikoeritrin extraction results. The aim of the study is getting the appropriate method to produce the red pigment of seaweed A. spicifera, obtain the pigmen concentrate that can be applied to the catfish sausage and determine the stability of the color pigment A. spicifera on application of catfish sausages during storage. The study consisted of two examination to obtain the best dose of A. spicifera pigmen. The first step is to find wavelength of fikoeritrin. The design of the study is completely randomized design RAK with 12 treatmens and 3 replications. The results of the study showed that the red pigmen A. spicifera can be used as a dye in catfish sausage with the best concentration of 0.75%. Concentration and storage time catfish sausage significant effect on the intensity of reddish and yellowish color, but not significantly different to the intensity of brightness and water content. The concentration of pigment A. spicifera different in catfish sausage on organoleptic test gives a significant difference in color, smell and flavor

Abstract Currently, African catfish is developing quite rapidly, because African catfish is one of the important commodities in the fishery. Efforts to increase the production of African catfish is to improve the quality of feed. The purpose of this study was to determine the effect of the use of shark waste mill on the growth rate, feed efficiency and survival rate of African catfish fishing. The research method was experimental with completely randomized design (CRD). The research consisted of five treatments and four replications. The treatments used were: (A) shark waste mill at 0% and fish mill by 50%, (B) 5% shark waste mill and 45% fish mill, (C) 10% waste shark mill and 40% fish mill, (D) 15% waste shark mill and fish mill and 35% (E) 20% shark waste mill and 30% fish mill. The main parameters measured were growth, feed efficiency and survival rate. Supporting parameters measured were water quality. Analysis of the data using analysis of variance (ANOVA) and to determine the differences between treatments tested by Duncan Multiple Range Test. The results showed that the giving of shark waste mil on ration had highly different effects on growth rate and feed eficiency of african catfish. The feeding of waste shark mill in ration had no significantly different effect on Survival Rate (SR). The best dose of shark waste mill is treatment C (10%) with growth rate (1,26%/day), feed eficiency (38,64%) and survival rate (55%).

Abstract The main obstacles in successful production is the attack of a disease. Preventive measures in reducing disease one of them is by means an increase in immunity the body of fish use natural compound (Parelberg et al., 2005). One of the natural compound that can be used as obtaining the immune system fish are the vitamin C, iodine, tannin (Bachtiar, dkk., 2012) and polysaccharides and derivatives as fucoidan. (Castro et. al., 2006) which is in Sargassum sp. With the provision of extract Sargassum sp. in feed is expected to optimize the number of erythrocytes and differensial leukocytes (number of neutrophils , monocytes and lymphocytes) at african catfish (Clarias gariepinus) so that it may optimize immunity the body of fish (Brown, 2000). The result of the observation of the blood of fish test is the use of extract Sargassum sp. wich get mixed in feed with doses 5, 10 and 15 g/kilogram feed during 21 days impact on the number of erythrocytes and prosentase lymphocytes blood catfishes. In doses C (15 g extract/ kilogram feed) put a value erythrocytes highest in day 21 namely 16.84 ± 1.56 x 105 cells/mm3, and give prosentase lymphocytes highest in day 21 than those wich others are 86.00 ± 3.81 %. But in a post test, B and C not seen the real difference between treatment. While for statistics the addition of extract not indicates the influence of real to the percentage neutrophils and monocytes of the blood fish. So that it can be said that addition extract Sargassum sp. with doses 15 g extract/kilogram feed give the effectiveness of the optimal response immune system than second doses other.

Published: February 2019

Environmental problem is a problem that must be solved by all parties, including students. Responsible environmental behavior arises from awareness of environmental issues. This awareness led to intention and determination of student to set their attitude and behavior towards the problems they faced. Responsible environmental behavior is basically the result of interaction between various factors. Factors that may affect the responsibilities behavior among the personality and the environmental sensitivity. This study aims to determine the effect of personality and environmental sensitivity on the responsible environmental behavior that students have. Research conducted at SMA Labschool Jakarta on the Semester I of 2018/2019 school year. The method used is the survey with quantitative-causal causal approach and path analysis. The sample were 79 students of class XI MIPA. Based on hypothesis test, the value of the path coefficient of X1 to X2 is 0.495, path coefficient X2 to X3 is 0.028, and path coefficient X1 to X3 is 0.568 but the path coefficient X1 to X3 through X2 cannot be calculated. Based on these results, it can be concluded that environmental sensitivity is not suitable as a mediator of variables between personality and responsible environmental behavior.

Published: February 2019

El objetivo de la investigación presentada es conocer factores asociados con la victimización de los adolescentes de 12 a 14 años a través de Internet y el teléfono móvil y la incidencia de la ciberagresión en la cibervictimización. Para ello se ha llevado a cabo una investigación por encuesta sobre una muestra de 4.536 adolescentes de Educación Secundaria Obligatoria de seis comunidades del estado español. Los resultados de este estudio arrojan luz sobre los factores predictores de la cibervictimización. Se constata la incidencia de la cibervictimización en la ciberagresión y la existencia de factores presentes de las cibervíctimas, como que son más conscientes de los riesgos en los entornos virtuales y utilizan con más frecuencia las plataformas digitales. Además, desarrollan estrategias de protección en forma de competencias digitales: bloquear a usuarios, establecer opciones de privacidad, denunciar fotografías indebidas, entre otras. No se ha podido constatar la incidencia del sexo en la ciberviolencia, siendo la prevalencia del fenómeno moderada y afectando de forma similar a chicos y chicas. Una conclusión importante es que el bucle circular de la violencia actúa convirtiendo a las víctimas en potenciales agresores, con las implicaciones que ello conlleva sobre la perpetuación y expansión del fenómeno.

Published: February 2019

La disponibilidad objetiva de alcohol (DO) se asocia al incremento del consumo de alcohol y problemas asociados. Variables cognitivas (p.ej., disponibilidad percibida de alcohol [DP]) también se relacionan con un mayor consumo. Objetivos. Se analizó la relación entre DO y DP con el consumo de alcohol, consecuencias negativas, la compra de bebidas alcohólicas y dinero gastado en alcohol dentro y fuera del área de residencia. Métodos. Participaron 356 jóvenes universitarios/as de 18 a 30 años residentes en la ciudad de Córdoba (Argentina) que completaron una encuesta online durante el año 2015. La DO fue determinada a partir de información provista por el gobierno municipal. Resultados. En las mujeres, una mayor DO y DP se asociaron significativamente con la compra de bebidas en esos negocios, consumo de alcohol, consecuencias negativas de este consumo y dinero gastado dentro del área de residencia. En los varones, la DP se asoció con la frecuencia mensual de consumo mientras que la DO y la DP se asociaron con la compra de bebidas en esos locales. Conclusiones. Los resultados, de utilidad para el planeamiento de intervenciones de reducción del consumo, indican una sensibilidad diferencial de hombres y mujeres a variables contextuales y cognitivas que regulan el consumo de alcohol.

Authors: Palacios Jorge
Published: February 2019

El objetivo de este trabajo fue evaluar la confiabilidad, la validez factorial, de criterio y predictiva de un instrumento diseñado para medir autoregulación del consumo de bebidas endulzadas y carbonatadas. Para ello se utilizó una escala tipo likert de 15 ítems, aplicada en una muestra de 261 personas, entre 18 y 45 años de edad (M= 22.51) de México. Dentro de los resultados, el instrumento incorpora dos factores: 1) regulación afectiva y 2) regulación cognitiva, ambos factores resultaron válidos y confiables. Se encontró que una proporción de la muestra presenta dificultades para regular el factor afectivo de consumir bebidas endulzadas y carbonatadas, también se encontró que el control cognitivo disminuye cuando aumenta el nivel de consumo de refresco. Se plantea la utilidad del instrumento en la evaluación de la autoregulación del consumo de bebidas carbonatadas.
