| dc.description.abstract | The development of plastic scraping machines for the management of plastic
garbage is an important thing to pay attention to, considering plastic waste is one
of the big environmental problems today. One of the companies that manufactures
plastic grinding machines is CV. The Star Umroh Engineering. In this context,
there are problems associated with the actual design of the machine, namely the
question of the uncertainty of time and the cost of production expected with actual
events. The amount of time and cost of production on the product is due to the
production activity on the upper body components of the machinery, the lower
body of the Machinery and the shaft of the machine. Developments and
innovations in actual engine design are needed to reduce production time and
costs and contribute to the efficient management of plastic waste. Design for Cost
(DFC) and Design for Manufacture and Assembly (DFMA). Identification of
problems in this research is carried out using the Quality Function Deployment
Analysis method to obtain components that must be repaired immediately, namely
the upper body, the lower body of the machine and the tool of the knife (couples).
The result of the design proposal selected was the first concept variant (VK1) with
a weight of 90%, when compared to the actual design, the design of the proposal
experienced an improvement in design efficiency by 14.3%, a reduction in
production time by 16.4% and a savings in total production costs of 17.4%. These
results show that design improvements using DFMA and DFC integration provide
optimum outcomes in terms of cost, production time and increased efficiency of
the resulting proposal design so that it can address the uncertainty of time and
production costs experienced by the company exceeding the expected target. | en_US |
