Random experiment planning complete (Completely randomized design; CRD) split into 3 thamen 3 repeatedly all 27 3 cylinder tank fermentation tanks, each of 20 litres container size.
The experimental design was completely random (Completely randomized design; CRD) is divided into three treatments with three replications of three cylinders each, a total of 27 tanks each containing 20 liters fermentor.
Planning of randomized complete (Completely randomized design; CRD) is divided into 3 treatments, each 3 repeatedly each 3 tank total 27 tank. Each fermenter packing 20 liters.
