The technology that has been developed in recent years is the production of fusion welded plates between two different materials, for example, steel with other materials such as aluminum. Combining the two materials, aluminum and mild steel, will undoubtedly produce a material connection with good properties, for example, in a vehicle car frame. However, these two materials have different melting points, mild steel has a high melting point, and aluminum has a low melting point in the inner layer. This research aims to determine the welding results and the microstructure between aluminum plates and mild steel. The Cold Metal Transfer (CMT) welding process provides a potential method for joining dissimilar metals. In this study, various 4 mm thick aluminum alloys (Al 1100) were joined to 4 mm thick mild steel (SPHC) by CMT welding technology. It was concluded that combining aluminum alloys with mild steel using the cold metal transfer method was feasible. The optimum process variable for welding aluminum-mild steel dimensions 250 mm × 100 mm × 4 mm can be obtained with ER70S-6 wire, ArCO2 shielding gas, wire feed speed 13 m/min, and welding speed e8 mm/s.The tensile strength of the joint first increases and then decreases as the welding current increases, the highest tensile strength can reach 73.35 MPa.

During the Covid-19 pandemic, the need for food was one of the problems faced by the government. The government urges the public to do independent food planting using polybag planting media as one solution to overcome this problem. However, single-use polybags can increase the amount of plastic waste, which is still unresolved. This study aims to design the value of the knockdown polybag product and gain strength from the knockdown product design. Knockdown Polybag product design using the VDI 2222 method (Verein Deutscher Ingenieure / German Engineers Association). This method helps facilitate designing products and learning for beginners and can optimize the productivity of designers to find the most optimal and efficient problems. After determining the method used, the next step is planning, conceptualizing, designing, and completing knockdown polybag products. The result of the design concept from the VDI 2222 method is an alternative overall function (AFK) 2 which has a square cross-section, is cones-shaped to facilitate plant transfer applications on agricultural land, and uses a hook locking model, which is flexible, and easy to assemble and disassemble. The product design of knockdown polybags has been obtained to meet the needs according to those on the market. Therefore, knockdown polybags can be produced and used to make planting more accessible and reduce costs for farmers.

One of the processes commonly used in making plastic goods is the injection molding process. Every process in injection molding has a very important role. A less-than-perfect process will result in defects or failure in the product. To reduce product defects, one of the processes that must be researched is the barrel purging process. The purging volume on the mini injection machine using the V-line method is inconsistent, as evidenced by the fact that if the purging waste, or what is usually called an avalanche is weighed, it will produce a non-uniform mass. This research uses a mini injection machine with the V-line method which has 2 main steps to carry out the plastic injection process; dosing and injecting. Unlike injection engines in general, this engine does not have a check-ring to withstand back pressure. This machine uses a shut-off system as a replacement for the check-ring role. This machine has never been subjected to a purging volume consistency testing process. The consistency of the purging volume greatly influences the product uniformity results. The research method used in this final assignment is direct. Data collection and test specimen collection will be taken directly on the mini injection machine using the V-line method. The steps taken in this research are planning, taking data, taking test specimens, processing test specimen data, and comparing test specimen data to obtain analysis results. The research results show that the mini V-line injection machine cannot support mass production, because increasing the screw rotation speed will affect the consistency of the volume of plastic that will be produced in the barrel, causing production to not run quickly and precisely.

ATMI Duta Engineering company is a manufacturing company engaged in the field of sheet metal with a material cutting process using laser cutting technology. Sheet metal products produced at ATMI Duta Engineering company is very diverse, one of which is the base cabinet. The base cabinet has main components, one of which is the shelf. Based on the data obtained from the interview process, there are problems, namely the shelf has never been analyzed, there are no finished products, and there is a risk of damage due to excessive loading. The solution to the shelf problem is to carry out a shelf design analysis using the finite element analysis method through Solidworks CAE software. The CAE simulation was applied to 27 variations of the shelf design by combining 3 test variables, namely the shelf model, the reinforcement model, and the thickness of the material. The material used in the simulation is SPCC material with a thickness of 1mm, 1.2mm and 1.5mm. The CAE simulation results obtained are then compared with reference to the SEFA 8M-2016 standard. The loading given in the CAE simulation is ± 108 kg (1.2 SEFA standards). The strongest variation obtained from the elimination process is variation 19 with a combination of shelf model 1 design, reinforcement model A, and with a material thickness of 1.5mm. Variation 19 meets the SEFA 8M-2016 standard because the displacement value is 1.065mm and this value is smaller than 6.35mm.
