Abstract

ABSTRACT The purpose of this study was to determine the provision of combinations of urea, ZA, and TSP to the growth rate and extracellular polysaccharide content of Porphyridium sp. The study was conducted using a completely randomized design (CRD) with combination treatment of fertilizer: A (25 mg / l of urea: 30 mg / l ZA: 10 mg / l TSP); B (50 mg / l of urea: 30 mg / l ZA: 10 mg / l TSP); and C (75 mg / l of urea: 30 mg / l ZA: 10 mg / l TSP). Control treatment in the study carried out by using fertilizers conwy and apart from the design above. The parameters observed were the density of population, growth rate, and the content of extracellular polysaccharides. The data were analyzed using ANOVA at α = 5%. The results of data analysis showed that the combination treatment of fertilizer significantly affected the rate of growth, population density, and the content of extracellular polysaccharide Porphyridium sp. Growth rate, population density, and the content of extracellular polysaccharide Porphyridium sp., sequentially obtained from a fertilizer with a combination treatment of urea concentration 75 mg/l, 50 mg/l, and 25 mg / l. Keywords: Porphyridium sp., growth rate, and poplation density
