Abstract
The problem of plastic waste is a growing environmental issue due to the high use of single-use plastics in households and small industries. One effective and efficient solution is plastic waste processing technology using a portable hot press machine based on induction heating and nickel-iron wire. Induction heating systems have higher thermal efficiency than conventional heating systems because heat is generated directly in the metal medium through an electromagnetic field, while conventional heaters, using nickel-iron wire, serve as resistive heating elements to maintain stable process temperatures. This study aims to analyze the characteristics of plastic waste processed using induction-based and conventional portable hot press machines and to analyze the electrical power requirements for households and MSMEs for reuse in the production of useful and valuable products. The research method used literature reviews from the latest national and international journals on hot press technology, induction heating, plastic waste recycling, analysis of process energy requirements, and analysis of the mechanical characteristics of the resulting products. The results show that the use of induction heating can increase energy efficiency and produce more even heat distribution compared to conventional heating. The characteristics of the pressed material show increased density, hardness, and structural homogeneity at an optimal temperature of 128-165 C for recycled plastic waste. Electrical power analysis shows that the machine power consumption is around 1.5-2.5 kW, making it suitable for use in electrical installations for medium-sized households and MSMEs. This technology is considered effective in supporting plastic waste reduction and the development of household products based on a circular economy
