| Abstract |
| Odor from food waste have an aesthetic effect on neighboring residents. Therefor it has been continued effort to reduce the problem. The purpose of this study was to decrease food waste odor by using nightsoil treatment sludge including Bacillus (SB). Statistical method by Minitab software was used for effective experiment plan and describing the result. Surface response methods with central composite design (CCD) was used for implementing. Utilizing CCD, one of the experimental design, the impact of three variables such as temperature, time and SB was estimated. Statistical analyses (analysis of variance, ANOVA) of the results showed that three variables influenced reduction of food waste odor (p<0.05). The coefficient of determination (R2) for odor reduction was calculated to be 0.9613, indicating that 96.13% of the variation was explained by the model. Through the analysis, input concentration of SB was found to be the most significant factors and followed by time and temperature. |
