Abstract

Environmental influences can cause corrosion or damage to materials, which is why paint coating is used to protect them. Some of the factors that affect the quality of the paint are technical, such as setting the air pressure and spray gun nozzle spacing. The experimental research aims to determine how air pressures of 1.5, 2, and 2.5 bar and nozzle spacings of 10–15–20 cm affect the gloss and thickness of the water-based paint layer. A gravity-feed spray gun was used for this purpose. The luster test method uses an AMTAST AMN60 glossmeter with the ASTM D523-08 standard, and the thickness test uses a coating thickness gauge with the ASTM E 376-96 standard. The air pressure and the distance of the spray gun nozzle affect the gloss and thickness of the paint layer. Parameter 2 bar/15 cm yielded the highest gloss of 92.77 GU, while parameter 2.5 bar/10 cm resulted in the highest coating thickness of 0.26 mm.

Abstract

In carrying out the design process, the main factor that must be considered is the lifting strength of the crane against the maximum load borne. Because the inaccuracy of the design process can result in malfunctions, even causing work accidents. Therefore, it is necessary to do the right design so that it can be used safely. In this design, the design of a lifting aircraft with a single girder gantry crane is designed with a lifting capacity of up to 2 tons, a lifting height of 4 meters, and a transfer width of 5 meters.. The design method used is by substituting the values ​​and other factors needed into the known equations to obtain the final result. To determine the maximum tensile strength of the load in this crane design, the equation for the maximum tensile force is used to obtain a result of 633.12 kg. Then for the steel rope chosen in this design is the 222 wire construction with parallel positions. By using the equation for resistance of the motor to movement, the power needed to move the crane is also 23,215 HP

Abstract

This service aims to overcome the problem of paper waste management to destroy unnecessary archives at the partner, namely the Directorate of Law and Administration of Surabaya State University. At the partner, the destruction process is carried out by shredding using scissors and tearing it into pieces. This method is ineffective and inefficient because it requires a lot of energy and a long time. In fact, in forced conditions, burning is carried out. This creates new problems, namely in the long term it will encourage climate change and environmental pollution. The solution to solving this problem is to process paper waste using a waste shredding machine to increase the recycling process and reduce the impact of climate change due to waste burning. The implementation method includes socialization of PKM-LK to partners, activity planning stage, manufacturing stage, paper shredding machine function test stage, training and mentoring stage, TTG (Appropriate Technology) implementation stage, and monitoring and evaluation stage. The results of the activity show that using a waste paper shredder machine is effective, efficient, and can reduce climate pollution due to waste burning with the number of sheets of paper processed per hour ± 2570 sheets, and the total weight of paper processed ± 12.83 kg. The recommendation from this study is to expand the market, machines can be designed with varying capacities, from small scale for SMEs to large scale for companies.

Abstract

Suspension technology on the vehicle provides a comforting effect with shock absorbers and a safety effect in driving and reducing the accident rate. The suspension system was developed by changing the construction and mechanism as well as the addition of a control element. Variable Geometry Suspension (VGS) is the development of a suspension system by using an active actuator is Single-link which is used to change the geometry of the suspension. Geometry change can affect the performance of the suspension system, so a modeling approach is needed to analyze the performance of the VGS system. The VGS modeling uses a quarter-vehicle model and a multi-body model with an equation of motion system using a Kineto-dynamic model with a double-wishbone suspension type. The analysis method on the VGS uses input is bumpy-road to obtain system performance in body acceleration, suspension deflection, and tire deformation. The results of the VGS with the Kineto-dynamic model has a range of 2 mm in the variation of the single-link angle, the performance values ??in the body acceleration and tire deformation between the quarter-vehicle and multi-body models have the same oscillations until steady, while the suspension deflection in the Kineto-dynamic model differs in the first oscillation with a steady time of 1.6 seconds. Therefore, the Kineto-dynamic model can be used to approximate the actual system.
