- Abstract
Three species of microalgae were used in this study, namely Nitzschia sp., Porphyridium sp., and Tetraselmis sp., which collected from the Lampung Agency of Maricultures – Ministry of Coastal and Marine Affairs. They were cultured in room temperature with 12:12 day light and given different salinities and pH for treatment groups with complete randomized design. Nitzschia sp. and Porphyridium sp. were treated within factorial design 2x2, namely 20 and 40 ppt in salinities and 5 and 10 in pH, while the Tetraselmis sp. was given with factorial 3x3, namely 10, 15, 20 ppt of salinities and 5, 8, 9.5 in pH. All the cultures for 7 days were replicated 3 times. Analysis of variance followed by LSD at 5% level of significant was applied to analyse the data on specific growth rate and total lipid contains. The results indicated that highest growth rate of Nitzschia sp. was in 20 ppt of salinity and at pH of 10, while Porphyridium sp. was in 40 ppt salinity and at pH of 5. But the highest lipid content of Nitzschia sp. was in 40 ppt of salinity with 5 pH, and Porphyridium sp. was in 40 ppt of salinity and 5 in pH. Tetraselmis sp. had the highest growth rate in 20 ppt of salinity and at pH of 9.5, but the highest total lipid of it was in 10 ppt of salinity with 9.5 pH.
