WebThe experimental design used was a Factorial Random Block Design which consisted of two factors and was repeated 3 times. The first factor is rice husk biochar (A) consisting of 3 levels, namely 0 g/paralon, 4000 g/paralon and 8000 g/paralon and the second petroganic factor (P) consists of 3 levels, namely 0 g/tan, 1 g/tan and 2 g/tan. WebFor two-level full factorial design, the number of runs can identify on the basis of 2 K formula, where 2 indicates the level and K denotes the number of factors utilized during the experiment. If there are three factors with two levels to be optimized, then there will be 2 3 =8 combinations or runs, for the full factorial experiment.
