This problem related to the huge number of rubbish. Many ways have been conducted to solve this problem. One way of processing rubbish is by machine. Producing machine for rubbish commonly is crushing machine or pressing machine. The purpose of this thesis is to design pressing machine for organic rubbish by capacity 250 kg/hours. This design is based on the integrated concept of cutting system from pressing result. Crushing system is designed by using knives arrangement that is rotated in its axes. The pressing process is designed by using shaft wheel mechanism and pressing plate that is equipped by spring. While, cutting system by using 2 blades is positioned rotating in axes end. The design is initiated by calculation of machine capacity and is continued by calculation of driving force of electrical motor. Then, there is needed calculation of design machines components needed; they are knives, axes, pulley and belt, cone gearwheel, axis, shaft and crank mechanism. Besides, there is also needed supporting system planning contains knives seizer, crushing cylinder wall, frame and machine cover and pelat mechanism and spring. The result of design is machine that consists of 3 systems; they are crushing system, pressing system and cutting system. This machine needs driving force of electric motor by 2,5 HP (1,84 kW). Crushing system by using 7 movements of cutting knife in the axis by speed of rotation 300 rpm. Pressing system is using mechanism of shaft wheel boost pressing piston. Shaft movement has speed rotation of 60 rpm, it means there is 60 times rotation in a minute. Cutting system by using 2 blades is moved by axis in 30 rpm. By this speed, then in every minute there is 60 times of cutting process to compensate pressing movement.} }
