BIOMASS PRODUCTION OF MICROALGAE Spirulina platensis WITH DIFFERENT CULTIVATION MEDIA AS AN ANTIMALARIA MATERIAL
Abstract
Spirulina platensis microalgae contain high protein and can reach 70% of its dry weight. Other content as antioxidants to prevent the emergence of free radicals, its flour has the potential to be immunostimulant and antimalarial. The ability of this microalgae to produce various sustainable products is not yet balanced with the development industry that meets biomass needs. The purpose of this study was to determine the effect of fertilizer types on the production of S. platensis microalgae biomass and to determine the cultivation media that can produce the highest cell biomass. This study used an experimental method with a Completely Randomized Design. The treatments tried were the kind of fertilizers, namely grow more, KW21, liquid organic fertilizer, and eco enzyme. Replications 5 times. The variables observed were the independent variables, namely the kind of fertilizer given, and the dependent variable was cell biomass. Supporting parameters were light, pH, and brightness. Biomass data were analyzed by the F-test to determine the effect of treatment and continued with the LSD test to determine the differences between treatments. The results of the study showed that the treatment of fertilizer types caused the S. platensis cell biomass to be different. Media with KW21 fertilizer produced the highest S. platensis biomass.
