T he current condition of n on t ax s tate r evenues in th e marine sector, especially those obtained from i ndustrial p orts and s pecial t erminals has not been maximized. This paper aims to identify what causes the non tax state revenues acquisition of i ndustrial p orts and s pecial t erminals to be less than optimal and to seek policy recommendations that can be implemented to increase the non tax state revenues . From the results of the analysis, it is found that several current problems are caused by the existence of i ndustrial p orts / s pecial t erminals which is not active and has not made non tax state revenues payments, low non tax state revenues rates on i ndustrial p orts and s pecial t erminals when compared to s tate o wned e nterprises BUP, the existence of tariff class differentiation, there is no SOP that regulates performance of i ndustrial p orts / s pecial t erminals and several other problems. From these problems, several policy recommendations were made, such as controlling permits and payments, strengthening h arbor master, adjusting water leases, integrating digita l platforms, implementing upper limit rates, intensifying and extending efforts. The policy is mapped based on the risks and implemented gradually over a period of two years starting from the quick wins phase, the short term phase, the medium term phase an d the long term phase. Each phase is simulated using dynamic simulation in the form of causal loop to see the projection of the non tax state revenues
