The dissertation was passed with a satisfying predicate.
The dissertation compared the predictive power of two behavioral change theories (i.e., the Planned Behavior Theory and the Social Cognition Theory) on the behavior of sorting household waste. This study aimed to build a framework for changing the behavior of environmental care. It was conducted by survey method and quantitative analysis. The population of this study was households in Semarang City and the analysis unit was an individual as a household member. The results of the study concluded that the Planned Behavior Theory and the Social Cognition Theory were able to predict the individual behavior of household waste sorting. However, the Planned Behavior Theory is more predictive than the Social Cognition Theory. The Planned Behavior Theory can predict significantly individual intentions to sort household waste through perceived behavioral controls.
