Abstract

The manufacturing process is an activity of processing raw materials into products to increase added value. One of these products is chair furniture; to reduce errors and failures in its manufacture, it is necessary to do prototype model experiments first. This research conducts a simulation study and analysis of the chair design on stress, deformation and safety factor using the Finite Element Method approach with the help of ANSYS ADPL 18.0 static structural software where the chair design is made of 304 stainless steel, aluminum-T6, HCP 30 polymer foam in one chair structure by simulating several static load loading scenarios, boundary conditions, and even distribution on the surface of the chair. The simulation results show that the highest maximum stress distribution (von misses stress) is 3.5 Mpa at a pressure of 175 kg.f, for the lowest value of 1.5 Mpa at a pressure of 5 Kg.f and a deformation (displacement) of 0.145x10ˉ4 mm occurs at a pressure of 175 Kg.f, while the lowest deformation value of 0.621x10ˉ5 occurs at a pressure of 75 Kg.f, This is due to the loading increasing along with the applied pressure force, but still in the minimum safety factor standard position for static loads, so as not to damage the geometric structure.

Abstract

This study aims to analyze the effect of borax as a flux on the melting performance of recycled 3004 aluminum from beverage can waste. The melting process was carried out using an oil-fueled furnace with six borax variations, ranging from 2.5 g to 15 g for 500 g of recycled aluminum. The results showed that the net aluminum mass increased from 209 g to 293 g, while the slag mass decreased from 242 g to 139 g. Linear regression analysis revealed a positive correlation between borax and net mass (R² = 0.9116) and a negative correlation between borax and slag (R² = 0.9135). Therefore, borax proved effective in increasing the yield of clean metal and reducing slag during the recycling of aluminum.
