Abstract
The economic downturn is among the worst enemy to all mankind. This study was

designed and developed based on engineering techniques and properties of bananas to provide a

manual driven low cost banana slicing machine. The development of this machine begins by

identifying problems that concerns the consumer, and targeted local entrepreneurs because

imported machine costly as well. It also studies the banana chip processing available in the

market.
The machine is based on the concept adapted from the problems. Next, careful material

selection process begins in order to make sure the material is safe and low-cost. Then,

forecasting and estimating the total selling price.

The banana slicing machine mainly consists of feeders, cutter, shaft transmission of the

motion of the cam and the follower, base support and frame. The researcher assumes a minimal

force to apply to be able to use by anyone. The researcher allowed the user to adjust the

installation of the blade (strings) in order to maximize the option of different shapes of the

banana.
