Abstract

As one of the staple foods, cassava will rot two to five days after harvest if not properly cared for after harvest. It is quite vulnerable to hazards. The post-harvest process includes making high-quality products such as cassava chips. In the production process, an effective mechanical tool or machine is created to produce uniform pieces of cassava chips. The tool used is a cassava chopper machine. The purpose of this research is to design a cassava chopper with sufficient capacity and have a uniform thickness of slices. The design process helps entrepreneurs make cassava chips in every way to increase the productivity of making cassava chips both in terms of quality and quantity. The results of the design of the cassava chopper machine carried out are obtained results: (1) The design of the cassava chopper machine uses iron material 58cm wide and 63cm high (2) The cassava chopper machine transmission system changes the rotation of the electric motor from 2800 rpm to 153 rpm. With components in the form of 2 pulleys B1 top diameter 510mm, pulley B1 bottom diameter 28mm, connected with v-belt B-81. The performance test of the cassava chopper machine is able to produce chopped cassava from 60 kg / hour to 66kg / hour with uniform chopping results.
