<![CDATA[This organic waste chopper is a tool that destroys organic materials such as leaves, grass, trims, tree branches, and tree fronds by chopping them into small pieces. The design process was done by creating a shredding knife design, a stirrer system, and a filtering process. The Design chosen from the existing literature was one with the simplest method that was easy to make, cheap, and practical when operated. This research aimed to increase the number of crescent blades on the machine organic waste chopper to make it more optimal, Design and calculate the chopper machine transmission system, and Calculate the capacity of the chopper machine. In this research, the method used is quantitative with a literature study approach and making observations about organic waste chopping equipment. The crusher, chopper, and stirrer are made in the shape of a sickle with eight blades and are driven automatically via a dynamo with a simple rotating transmission system. The measuring instruments used in the research were a digital thermometer and a stopwatch. The electric motor (dynamo) used when testing the tool is 1 HP, 1400 rpm. The test was carried out 3 (three) times with a waste weight of 1000 grams each and resulted in an average chopping time of 20.3 seconds with an average chopping size of 1.53 cm. The transmission system components are the electric motor, pulley, v-belt, transmission shaft, bearings, and pins. The results of the transmission system calculations are: pully speed 5,4 , number of v-belt revolutions 4,568 reps, belt life 108.98 working hours, tension on the shaft 1747.15 l , Shear stress on the peg 493 .5 , the compression stress at the pegs is 986.9 , and the bearing life is 1.128 × hours. The chopping capacity of the trial results is 2.95 ..]]>
