Abstract

The importance of analyzing rainfall is expected to help in handling disaster-prone areas, so that the consequences can be minimized. This study aims to determine the intensity of rain in the short term. The data used in this study is the annual rainfall data in Java for 2005 - 2019 for each province. The method used in this study is the Mononobe Method to see the intensity of daily rain and its daily return period. The results of this study indicate that the intensity of rain during the duration of one hour to three hours decreases quite significantly, but at the duration of four to eight hours the decrease in rain intensity is not as big as the decrease in the duration of one hour to three hours. The highest rainfall intensity is in the one hour duration in West Java Province. However, the intensity for the five to eight hour duration tends to be the same for 6 provinces in Java. The rainfall threshold in Java is included in the category of heavy rain. High rainfall intensity lasts for a short duration, on the other hand, rainfall with low intensity tends to occur over a relatively long duration
