Abstract

Plastic’s function in human lifestyles is expanding. This boom is because of the truth that plastic is lightweight, realistic, and reasonably priced and can replace other objects features. Plastic use is hastily increasing in East Nusa Tenggara Province, especially in Kupang town, as evidenced by the enormous use of plastic gadget. Some people in Kupang town see this problem as a possibility and opportunity to create jobs and a generate of income by gathering plastic waste to be sold and despatched to some other island to be recycled. Therefore, this study focused on designing and fabricating a low-cost plastic shredding machine that will assist plastics collectors as small and medium-scale entrepreneurs in the city of Kupang in chopping plastic waste i.e. bottles and cups into small fragments, making it easy to pack and ship it. The plastic shredder machine is made up of four major parts: the hopper, the shredding unit, the power unit, and the machine frame. The design parameters, such as hopper capacity, shaft diameter, reducer ratio, and required power, have been calculated. The result of the calculated design parameters was being used for fabrication. The uniqueness of this plastic shredder machine lies in the uniqueness of its design where at the bottom of the shredding unit there are a metal sieve with the geometric shape of arc that allows the recirculation of crushed plastic not conforming to the appropriate size to reintegrate it in the shredding process. This metal sieve will ensure the chopped plastic are uniform in size. The performance evaluation of the machines was determined in terms of the machine efficiency and the production rate. Following the successful completion of the fabrication, the shredder machine is tested using 4500 gr of the plastic bottle and 2600 gr of plastic cups as a sample, with the succeeding results obtained: At a machine speed of 135 rpm, the plastic bottle was shredded to an average particle size of 30 mm 2 in 840 sec, and plastic cups was shredded to an average particle size of 28 mm 2 in 400 sec. The average machine efficiency was 98% for plastic cups, and 94% for plastic bottle.
