DESIGN OF A TOBACCO CRUSHER USING TWO BLADES WITH 135 WATT POWER

This research aims to design and build a tobacco shredder using two blades driven by
a 135 watt electric motor as an appropriate technology solution that can improve the efficiency
and quality of shredded tobacco. The background to the design of this tool is based on the fact
that many tobacco farmers still use manual shredding methods, which require high skills, are
time-consuming, and carry a high risk of work accidents. The research process was carried out
through several stages, namely tool design, component manufacturing, assembly, and tool
performance testing. The test results show that the machine is able to shred tobacco with an
average time of 23.33 seconds for 1 kg of tobacco, with a working capacity of up to 160.7
kg/hour. Mechanical calculations on machine elements such as the shaft, frame, and
transmission system show that all components work within safe limits. Shear and bending
stresses are below the maximum material limits, with a fairly high safety factor. Thus, this tool
is not only technically effective but also safe and economical for use by small to medium-scale
tobacco farmers. It is hoped that this tool can be an alternative to modern tobacco shredding
that can reduce dependence on manual processes and increase productivity and quality of
agricultural products.
