Productivity Of Spirulina Fusiformis, (Vorinichin) In Plastic Photobioreactor With Sun Light Filtering

Recently climate change has become a complex issues which have relation with many problems in the world, one of them is food security. Based on these problems, we need alternative food resources which have high productivity characteristic. Besides that, such resource should be able to be grown in critical and limited land. Microalgae as an alternative food resource give us a hope to have sustainable food resource in the future. Microalgae can grow up fast and do not need wide and fertile land. In other hand, Microalgae culture that can be performed in outdoor, especially Spirulina fusiforrnis, faced issues like expensive cost culture and the high intensity of sun light in field. Based on these problems, the research was conducted for develop cheap flat Photobioreactor (plastic) which is equipped by sun light filter system. The objective of this research is to find out the percentage of sun light filtering that can give high productivity and high protein content. The method used was experimental method, using a Completely Randomized Design (CAD) with six treatments (percentage of the filtering by sunlight 0%, 50%, 60%, 70%, 80%, and 90%. ) and four replications.. Parameters measured were growth, levels of protein, pH, temperature, and light intensity. Research results showed filter sun light treatment influential real against productivity S. Psiforruis. The bighest productivity obtaized at 50% eater sun light tretearent (FS), in the amount of 0.063 g/L/day. The highest protein content obtained at 70% sun light filtering treatment, which is equal to 49.83 %.
