Polyethylene Terephthalate plastic is a type of plastic that is often used as disposable beverage bottles so that excessive use has an adverse impact on the environment. In addition, the process of decomposing this plastic is relatively long, it takes years to decompose PET type plastic. PET waste recycling methods are currently still rare to be able to process PET into semi-finished goods and finished goods, so it is quite difficult to obtain goods that have high function and economy. PET is a type of plastic that is easily reformed, so one effort that can be done to take advantage of this waste is to make PET waste into filaments by recyclingof waste. Therefore the aim of this research is to design a pultrusion for making filament using PET waste where the machine uses Arduino assistance as a machine control system, especially the process of controlling temperature and pulling speed. The experimental method was used in this study by adding a cooling fan during the withdrawal process. This is intended so that the filament hardens quickly and the diameter of the filament produced is uniform. The parameters used are a temperature of 205 °C and a pull speed of 30 rpm. The result obtained is that the filament has a uniform diameter, shiny color and has a smooth surface.
