PERANCANGAN MESIN PENCACAH SAMPAH PLASTIK JENIS BOTOL MINUMAN KEMASAN

Abstract

Plastic waste, especially beverage bottles, is one type of waste whose quantity continues to increase and is difficult to decompose naturally, thus requiring more effective management efforts. One of the efforts that can be made is thru the design of a plastic shredder machine that can support the recycling process. This research aims to design a plastic bottle shredder using the VDI 2222 method to obtain a design concept that meets user needs. The VDI 2222 method is applied thru the stages of needs identification, demand list preparation, concept alternative development, concept alternative evaluation, and detailed design. The evaluation results show that Concept Variant Alternative (CVA) 1 received the highest score of 88, compared to CVA 2 with a score of 79 and CVA 3 with a score of 76, thus it was chosen as the best concept to be developed in the detailed design stage. The selected concept is deemed capable of meeting the aspects of functional achievement, ease of manufacturing, ease of assembly, ease of maintenance, safety, as well as production and manufacturing costs. Thus, the VDI 2222 method can be used as a systematic approach in determining the design concept of a plastic waste shredder.
