This research article aims re-design the initial process of local-level policy. Mode simulation testing used to look beyond some concepts that can affect the initial policymaking process. The concept is policy diffusion and dynamic system model this concept was dug through the deductive by searching some of the scientific literature findings to the theme of research. The methods used to a model-building method, a way to reconstruct the theory by means of re-establishing various models. The model is derived from the theory, or simplify the concept or theory that involves the relationship between the concept of an internal concept. The results of this study reveal, the rising or declining public trust is also influenced by the policy. The new way is considered necessary due to the higher probability to produce a quality policy with simulate various concepts that are considered can translate a variety of phenomena in the form of public policy issues. When public distrust is increasing, then that response, and a warning to the government to put more effort into improving public trust through policy.
