Abstract

The waste discarded by the community every day comes from agricultural activities, markets, households, entertainment, and industry. One form of waste is domestic waste, which originates from household waste. The increase in domestic waste goes hand in hand with the development of physical infrastructure and the expansion of adequate facilities and infrastructure. As a result of this pollution, environmental balance is disrupted. In this experiment, one method will be used to reduce or minimize environmental pollution, especially air pollution, by using an electrostatic precipitator as a tool to capture solid particles from exhaust gas in waste combustion smoke. It is expected to efficiently reduce the solid particle content in the exhaust gas from waste combustion. The electrostatic precipitator is an alternative for reducing environmental pollution, as it has high efficiency, reaching 98.4%, and can capture particles as small as 100 micrometers. The electrostatic precipitator works by capturing solid particles that pass through the particle charging area, which is at a high potential. The charging area provides high-speed electrons by ionizing molecules and particles in the exhaust gas from the smoke. The exhaust gas particles receive positive ions and become highly charged, allowing them to be attracted and captured by negatively charged electrodes (collecting plate). Through this process, the solid particle content in the exhaust gas from waste combustion can be eliminated. Therefore, this final project involves the development of an electrostatic precipitator prototype aimed at reducing environmental pollution, particularly air pollution.

Abstract

Automated Guided Vehicles (AGVs) are a smart transportation solution that is increasingly being used in industry. The stability and strength of the chassis are critical factors in ensuring AGV performance when carrying loads. This study examines the effects of load variations and material types on the structural performance of AGV chassis through an experimental approach and numerical simulation based on Finite Element Analysis (FEA). The materials used were ASTM A36 and ASTM A500, with loads of 5 kg, 10 kg, and 15 kg. A chassis design with dimensions of 400 × 300 × 80 mm was modeled and analyzed using Computational Fluid Dynamics (CFD) software. Validation was performed through experimental testing using a dial indicator. The results show that at a 15 kg load, ASTM A500 experienced a maximum stress of 60.15 MPa and a deflection of 0.00078 m, lower than ASTM A36, which reached 68.06 MPa and a deflection of 0.00089 m. The difference between the simulation and experimental results was well below 10%. Similarly, regarding the safety factor, ASTM A500 has a value of 2.7145 at maximum load, indicating that this material has a higher safety margin compared to ASTM A36. Based on these results, ASTM A500 is considered more efficient and stable, and is more recommended for AGV chassis applications. This study highlights the importance of integrating numerical and experimental methods to produce optimal structural designs.
