Based on the results of the test data on the effectiveness of the rat repellent media, the average time needed by rats to move to the other side of the cardboard using mint leaf media was 9.86 seconds, 7.17 seconds for clove media and 10.72 seconds for coffee grounds. It can be concluded that the repellent media made of cloves is the most effective, then rat repellent media made of mint leaves and finally rat repellent media made of coffee grounds. This is because the media to repel rats from coffee grounds utilizes coffee grounds that have been brewed so that the odor from this media is significantly reduced. While the reason why rats do not like rat repellent media made of cloves rather than mint leaves is because clove rat repellent media has a more pungent smell than mint leaf rat repellent media.
