Abstract
The present research aims at knowing: 1) the influence of different concentration of diatom media fertilizer on the population density Tetraselmis sp.; 2) the influence of different concentration of KW21 fertilizer on the population density Tetraselmis sp.; 3) an optimal concentration of diatom media fertilizer and KW21 for the population density of Tetraselmis sp. An experimental with Completely Randomized Design was conducted by treating diatom media fertilizer and KW21 fertilizer. Each of the treatments was given concentration of 0%, 25%, 50%, 75%, and 100%. The results show that the concentration of diatom media fertilizer did give any significance influence on the population density of Tetraselmis sp. It could be seen from the value of F test which was lower than F table (23,05) > 3.48) at the significance level of 5%. The concentration of KW21 fertilizer had any significance influence on population density of Tetraselmis sp. by which the value of F test was 10,63 and the F table was 3.48 at the significance level of 5%. An optimal population density of Tetraselmis sp. fell on the treatment of A1B4C1 (94.83x10 5 cell/ml) and A2B4C1 (91.83x10 5 cell/ml).
