ABSTRACT
Density and hardness are physical parameters in the manufacture of refuse derived fuel (RDF) pellets. In making pellets, we also want to achieve a high heating value for the combustion system. This research aims to analyze the mixture of municipal solid waste to its density and hardness and study its correlation to heating value. The variable used in this research is a mixture of paper waste and garden waste and food scraps and garden waste. The density and hardness for the mix of paper waste and garden waste were 1970.6 to 2474.8 kg/m3 and 37.8- 42.8HA, respectively. The mixture of food waste and garden waste has density and hardness of 1822 to 2276.7 kg/m3 and 17.4-37.8HA. The correlation between density and hardness on heating values did not reach a significance of 0.05, so there was no strong relationship between density and hardness on heating values.
