Pertumbuhan dan Produktivitas Biomassa Mikroalga Laut Nannochloropsis sp.UHO3 Menggunakan Pupuk Yang BerbedaByIndrayani, Haslianti, AsmarianiFakultas  Perikanan dan Ilmu Kelautan-UHODipresentasikan pada Seminar Nasional Perikanan dan Kelautan Berkelanjutan III Fakultas Ilmu Kelautan dan PerikananUniversitas Halu Oleo14 September2019Hotel Claro, KendariIntroduction The Nannochloropsis sp.UHO3 is a newly isolated diatom from a coastal area in Kendari Nutrients affect growth and biochemical composition of microalgae Aim : to determine the growth and biomass productivity of a marine microalga Nannochloropsis sp.UHO3 Under different culture mediaFigure 1.  Scanning Electron Microscopy Images of  the Nannochloropsis sp.IND-UHO3 at 1000x Maginification (left) and 10000x Magnification (right)Materials and MethodsCulture conditions• Different media  (F/2, Walne, NPK, NPK+Urea, TSP+Urea)• 3%  salinity• Ambient room temperature• 12 h light and 12 h dark cycle• Batch mode for 2 weeksAnalytical methods• Cell counting using Neaubar Haemocytometer• SGR • Biomass Yield• Biomass ProductivityStatistical analysis• One Way ANOVA • Using Sigmaplot 14 Package (Systat-USA)Results and DiscussionFigure 2.

Biomass Productivity of the Nannochloropsis sp.UHO3 under different culture mediumConclusion The highest growth rate achieved when the alga grown in Walne medium and the lowest in f/2 medium but the biomass productivities of the alga showed no significant difference between different media. For low cost mass production of the alga biomass, the use of NPK+Urea or TSP+Urea is preferable.Thank You
