Abstract
Plastic waste has become a complex environmental problem. Indonesia as the second biggest country with plastic waste encounter serious problems in treating plastic waste. In addition, the lack of an effective system in treating and recycling plastic waste makes this problem more severe. Many efforts have been conducted to solve this problem. One of the solutions is to recycle plastic waste. Plastic waste can be sorted based on its properties and subsequently shredded into pellets. The pellets then can be transformed into new reusable products using an extrusion machine. This paper discusses the development of an extrusion plastic machine design along with its material selections, ergonomics aspect, static analysis, and cost. The proposed design is established in which the machine frame meets the ergonomics requirements. It is also considered that all components and materials to build the machine are available in the market and can be adjusted with the existing conditions. The safety factor for the frame is obtained to be 84, which implies that the proposed design has adequate strength. Moreover, by comparing to the extrusion machine available in the marketplace, the proposed extrusion machine can obtain the cost of about IDR 8,703,545.
