Abstract

Plasma cutting is a method of cutting metal, especially steel, with relatively low cost and effectiveness, with satisfactory results. Where in the cut, it is enough to need a plasma cutting machine/inverter that is quite affordable, widely available in the market, and simple tools, an air compressor (no special oxygen/gas needed as in gas/oxygen and acetylene/LPG cutting), a power source, the material being cut and the cutting process can be carried out. How to use plasma cutting is relatively easy, namely by setting the machine and then directing the plasma torch to the cutting plane as needed by maintaining a stable movement and height. However, when we make repeated cuts, our concentration and physical strength will automatically decrease, so we need a tool that can help us direct/adjust the plasma torch, which is called a plasma cutting mechanism. After paying attention to these needs, a plasma cutting mechanism was designed with a working space/cutting length of 1200 mm, with a tool size of 1400 mm x 300mm x 200 mm length, width and height, estimated cost of Rp. 3,050,000,-, with a cutting speed setting of 100 mm/minute to 1000 mm/minute, a cutting height of 0 to 10 mm with an angle of 0 degree to 90 degree.

Abstract

Shoe drying is a crucial process for maintaining hygiene and extending the lifespan of footwear, especially in high-humidity environments. This study aims to experimentally investigate the heat transfer characteristics of a flat-rack-based shoe dryer. The system is designed with electric heating elements and a horizontal rack configuration to promote uniform heat distribution. Key observed parameters include inlet air temperature, shoe surface temperature, drying time, and moisture content reduction. Measurements were conducted at multiple rack levels to evaluate vertical and horizontal temperature distribution. The results indicate that forced convection is the dominant heat transfer mechanism, with relatively uniform temperature distribution observed in the middle racks, while the top and bottom racks experienced temperature deviations. The heat transfer by radiation generated by the shoe dryer is 5.41 J/s, and the convective heat transfer is 238.8 J/s. The moisture content loss increases with drying time, indicating that 90 minutes is the optimal drying duration among the tested variations. This study provides a foundation for the development of more energy-efficient shoe drying systems and highlights the potential for integrating alternative heat sources such as solar energy.
