This study is aimed at developing an empirical model to estimate the heating value of municipal solid waste as a function of its element content (C, H, N, S, O). A correlation was developed using multiple stepwise regression analysis based on 29 samples of municipal solid waste that were randomly selected and gathered from 29 different areas in Semarang. Experimental results show that carbon and hydrogen are statistically significant predictors of the heating value. The model is

Furthermore, this work also indicates that if only the C content is known, the heating value can be estimated by HHV=-1737.55+143.33C kcal/kg (R 2 = 0.94 and Adj R 2 =0.94). These results show that the new correlations using regression method give accurate and excellent results that are closer to measured values.
