Analisis Pola Sebaran Stasiun Hujan Menggunakan Metode Kagan-Rodda Di Pulau Natuna

ABSTRACT
The number and location of rain stations is important in the accuracy of rainfall data in an area. This study examines the density of existing rain stations based on World Meteorological Organization (WMO) standards and rationalizes the number and distribution pattern of rain stations using the Kagan-Rodda method. This method analyzes the variation in error rates in the context of the Natuna Island area, which has a physiographic area of a small archipelago with an area of 2009.4 km² and has 1 rain station located in Ranai. This study used satellite precipitation data from the Global Precipitation Measurement (GPM) and data from a single surface rain station to analyze four variations in the length of the sides of the Kagan-Rodda triangle. This study produced four alternative numbers and distribution patterns of rain stations using the Z1 value standard below 5% and taking into account the WMO standard. The results of the analysis showed that the value of the coefficient of variation (Cv) was 0.175, r(0) was 0.832, and d(0) was 39.06 km from the daily rainfall data. In addition, r(0) of the monthly rainfall data is 0.873 with d(0) of 87.72 km. There are four alternatives with different numbers and distribution patterns. There is one alternative that meets the WMO recommended standards with a total of 9 stations from the area of influence per station using the Thiessen Polygon method. This study shows the importance of using GPM satellite data in rainfall calculations, especially in areas with limited rain measuring stations. Thus, the results of this research can be used as a basis for better infrastructure planning, such as flood control, as well as supporting sustainable water resource management on Natuna Island.
Keywords: WMO, GPM, Kagan-Rodda.
