    Policy evaluation on the distribution of disaster stimulant funds in Palu city by Nuraisyah Nuraisyah, Erdiyansyah Erdiyansyah, Aldi Aldi

    Published 2024-03-01
    “…The results of this study showed that the distribution of disaster stimulant funds in Palu City was not effective as the fund was only enjoyed by certain groups and had not solved community problems. This means that there are many complaints from the affected community as they have not been registered as a beneficiary of stimulant funds.This research contributes to the development of public policies related to the policy of distributing stimulant funds for victims of natural disasters consisting of earthquakes, tsunamis, and liquefaction, so policy formulation needs to be designed comprehensively so that it becomes a recommendation for the future because policies related to earthquake, tsunami, and liquefaction disasters have not previously occurred anywhere in the world so that the findings of this study become recommendations for the government in handling increasingly complex natural disasters.…”
