Pengaruh ukuran partikel arang dari limbah tutup botol plastik terhadap kualitas briket

Abstract

The amount of plastic waste increases with the increase in plastic use, especially in the food industry. Plastic waste is waste that is very difficult to decompose and takes a long time to spoil. Plastic bottle caps are a type of polypropylene (PP) plastic which is recommended to be used only once. The research objective was to determine the effect of particle size on the briquette characteristics of plastic bottles based on the proximate analysis. The proximate analysis carried out was moisture content, ash content, volatile matter, fixed carbon, and calorific value. The research design used was a burning temperature of 450 °C, a burning time of 60 minutes, and particle sizes of 40, 60, and 100 mesh. The results showed that the particle size of 40 mesh had the best characteristics, namely water content of 0.5±0,05%, ash content of 2±0,25%, volatile matter content of 15±0,51%, bound carbon content of 82.5±0,32%, and a heating value of 9,982.779±240,017 cal/gram. Based on the results of the proximate analysis, it can be concluded that a particle size of 40 mesh can improve the quality of briquettes compared to 100 mesh.
