Abstract

Production tools play an important role in determining the quantity and price of products or services produced by business actors. With the availability of adequate production tools, micro, small and medium enterprises can increase the amount of production in a more efficient time. Apart from updating production tools to sophisticated and modern tools, appropriate technology is one solution that can be used to reduce production costs. This study aims to identify the extent to which micro, small and medium enterprises in Tarakan City understand and utilize appropriate technology in running their business. In this study, a study was carried out related to the means of production used by micro, small and medium enterprises in Tarakan City. In the initial stage, a survey was conducted on the use of production equipment currently in use. Observation of the effectiveness and efficiency of production equipment is the next stage in this study. The production tools used by micro, small and medium enterprises are still using traditional equipment. With traditional tools, they feel they are able to meet sales targets. Some micro business actors also seem unwilling to update production equipment because they are worried about the increase in production costs.

Abstract

The chassis is the main component of an electric vehicle, serving as a supporting structure for all vehicle components and receiving loads during operation. Therefore, a structural strength analysis is required to ensure the safety of the frame design before the manufacturing process commences. This study aims to design and analyze the strength of a tubular space frame for an electric car using a computational simulation approach based on the finite element method. The frame model is made in three-dimensional geometry and analyzed against static loading with varying rider loads of 46 kg, 56 kg, and 66 kg. The analysis parameters used include Von Mises stress, displacement, and safety factor to evaluate the structural response to loading. The simulation results indicate that at a load of 46 kg, the maximum Von Mises stress is 18.09 MPa, accompanied by a displacement of 0.20 mm and a safety factor of 3.03. At a load of 56 kg, the stress increases to 22.02 MPa with a displacement of 0.24 mm and a safety factor of 2.49. Meanwhile, at a load of 66 kg, a maximum stress of 25.95 MPa was obtained with a displacement of 0.29 mm and a safety factor of 2.11. This maximum stress value is still below the material's yield stress of 207 MPa, so the frame structure is still in a safe condition under the applied load.
