| Summary: | Response Surface Method is a method used to find the relationship between
the independent variables and the dependent variable then optimize the dependent
variable. In general, response surface method consists of designing experiments,
modeling influential variable, and perform optimization. Response surface methods
have many experimental designs, classic designs such as the Central Composite
Design (CCD), Box-Behnken design (BBD) and Computer Generated as D-Optimal
Design. Optimal design requires little experiment so as to minimize the cost of the
experiment. D-Optimal criteria are used to minimize the variance of the parameter
estimates by maximizing the determinant of the information matrix determinant. The
selection of the points of the design depends on the model chosen and the desired
number of experimental units. In this thesis, D-Optimal criteria applied to the data on
the total lipid of microalgae Chroococcus Sp, 3 independent variables are based on
the cell density, the composition of nitrogen, phosphorus composition. it can be
concluded at the cell desdity=3.206026, composition of nitrogen=0.264478 g/l and
phosphorus composition=0.396292 g/l will result in the total lipid optimum
7.159689%. |
