摘要：Good rainfall data can be obtained from recordings that are maintained and monitored continuously. Thus, the more rain stations there are, the more detailed the rainfall data will be. The rain station network density is expressed as the area of the watershed represented by one rain station. Meanwhile, the pattern of distribution of rain stations states the location of the placement of rain stations in the watershed. Ternate Island with an area of 76 km2 and has stations located in Akehuda Village, Gamayou Village, Tabona Village, Sasa Village, Kastela Village, and Sulamadaha Village. This study aims to rationalize the density of rainfall stations in Ternate Island. Rationalization of rainfall stations using the Kagan-Rodda method. The results obtained for the rationalization of rainfall stations with a total of 5 rain gauge stations spread across the city of Ternate, which are located in the Tabam, Gamayou, Sasa, Dorpedu, and Togafo areas with a grading error of 19.27% with a network density of 4.17 Km2/station.
