The Pelawan tree has many benefits in the community, one of which is its leaves for making herbal teas. The process of making this tea uses a chopper machine. This machine has existed before, but the dimensions of the previous were too large, which is where the initial purpose of making the machine was to help the community MSMEs whose users were women/mothers. Besides, the results of the chopping were still rough. Therefore, the design of the machine was carried out by changing the dimensions to 370 mm x 350 mm x 530 mm with an electric motor of 0.34 Hp with a motor rotation of 1325 rpm. There are four variations of blades angle, namely 10˚, 15˚, 20˚, and a combination of the angle. The goal is to increase the fineness of the chop. The results showed that with 10˚ produces 45.3% smooth and 54.7% rough, for 15˚ produces 37.31% fine and 62.69% rough, for 20˚ produces 36.24% fine and 63.76% rough, for the combined corners produces 38.58% smooth and 61.42% rough. The maximum production capacity of this machine is at an angle of 10˚ of 0.78 kg/hour.
