Abstract

That cassava chopping machine has begun to be modified from what used to be traditional to now use an automatic machine which users hope can increase production productivity for small-scale producers. The automatic cassava chopper machine has advantages for small-scale industries because it is easy to operate and requires minimum production time. The cassava chopper machine is designed and manufactured to determine the dimensions of the components of the cassava chopper machine and determine the amount of power used to slice the cassava and determine the chopping method on the machine. The research calculation method uses quantitative research that uses numerical data to analyze. The initial experiment to conduct research begins with primary data collection, after which it analyzes the data so as to produce the desired output. This research and testing were carried out at Mr. Yudi's residence, which is located at Jl. Joyo Suko No. 24 Merjosari Malang. The research time is planned for June 2022. The results of the discussion that can be drawn from the design of a cassava cutting tool are that this cassava cutting tool has 4 blades with a cutting speed of 7.01 m/s, the cutting process is easy and able to improve the quality of cassava chip products. This machine has a power of 0.6 HP and uses a 1 HP power motor with a rotation of 2800 rpm. The general conclusions obtained from cassava chopping machines compared to traditional machines are that (1) the construction is simple, (2) it does not require large areas of land or space to operate, (3) the cutting process is shorter, and (4) it is easy to operate. Suggestions that can be given to the design of a cassava slicing machine and can be taken into consideration in further research are that when used the cassava chopper machine still generates vibrations so it requires rubber dampers to minimize vibration and the blades on the machine need to be maintained regularly.
