| This study aims to manufacture an integrated automatic control unit for the production of organic fertilizer in all steps of production for the fermentation period, by adjusting parameters throughout the process. There are 5 main components, namely: the frame is carrying the cylindrical body - power transmission system - water supply system - ventilation system - control system connected to sensors. The first mixture was made C1 and consists of cattle dung, shredded paper and field residues in proportions of 5: 1: 2.5 and the second mixture C2 was assembled from field residues, sugar cane residues and rabbit dung, the mixtures were made by 1: 0.5: 1.8. These percentages are determined according to the nitrogen carbon ratios of each waste type, which must be adjusted in aggregate to an appropriate entry ratio of 1:30. The variables studied are the speed of the stirring system with four levels (17, 22, 27 and 32 rpm), 3 levels of angles (45, 50 and 55 degrees) as well as three levels of processing time (600, 1200 and 1800 sec). To verify the efficiency of the mixing and mixing were identified 8 points and measure the moisture homogeneity in these points after stirring and add the amount of water initially fit the pile. It was concluded that better moisture distribution resulted from a 50-degree angle with a speed of 22 rpm and a 1200 sec processing time are the best parameters, That give a mixing efficiency. | ||||
