PENGARUH PENAMBAHAN MIKROALGA Spirulina platensis DAN MIKROALGA Skeletonema costatum TERHADAP KUALITAS SOSIS IKAN BANDENG (Chanos chanos Frosk) The impact of Microalgae Spirulina platensis and Microalgae Skeletonema costatum Addition on the Quality of Milkfish Sausages (Chanos chanos Forsk)

The development of human consumption on foods is increasing. Therefore, food enrichment is becoming the main focus to overcome the problems on food security that are high in nutritional value, quality, healthy, and acceptable to consumers. S. platensis and S. costatum are two kinds of microalgae that contain high protein and beta-carotene needed by human body. Nowadays, people have their preferences on fast food, such as fish sausage, which is favorable to consume. This research aims to figure out the impact of the difference in microalgae addition on the quality of fish sausage. The materials used in this research were milkfish (Canoscanos Forks), two kinds of Microalgae: S. platensis and S. costatum. The experiment design used was completely randomized design that consists of three different treatments: the addition of 10% S. platensis, the addition of 10% S. costatum, and without the addition of any Microalga in subtitution of the starch in thriplicates. The experimental parameters were protein levels, beta-carotene levels, emulsion stability, gel strength, water activity (aw) and sensory test. The data is analyzed using ANOVA, followed by Honestly Significant Difference (HSD) test on parametric data, meanwhile Kruskal-Wallis was used on non-parametric data. The result showed that the different in the addition of microalgae has a significantly impact (P<0,05) on; protein levels, beta-carotene levels, emulsion stability, gel strength, water activity (aw) and sensory test. Fish sausage with the addition of 10% S. platensis produced the best result of all the tested parameters, when compared to those with the addition of 10% S. costatum and without the addition of any microalga (control).
