Then put into containers / bottles that have been fitted hose,water manometer, and the gas holder. The research was done in stages with the conditions that you run.Variables that run is a comparison of raw material (1:1; 1:1.5; 1:2; 1.5:1; 2:1), observation time (5 days, 10days, 15 days, 20 days, 25 days , 30 days), and the variable addition of grass (50 gr, 100 gr, 150 gr, 200 gr).From the results of this study found the greatest level of 74.22% in comparison 1 (water): 1.5 (brown skin)with the addition of 150 g of grass while low levels of 60.04% in comparison 2 (water): 1 (brown skin ) withthe addition of 200 g of grass, the results of this study meets the National Standards of Indonesia.
