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
