Rasionalisasi Stasiun Curah Hujan Berdasarkan Metode Kagan-Rodda Dan Metode Kriging Di Wilayah Sungai Rokan

---

The distribution of locations and the number of ideal rain stations will represent
rain events to support the accuracy of analytical information in an area. The density
of existing rain stations was assessed based on the standard method of the World
Meteorological Organization, while the rationalization analysis of the number and
distribution of rain stations used the Kagan-Rodda method and the Kriging method.
So it is necessary to develop the scope of research with various physiographic
categories and river basins. The research location is the Rokan River Basin with
physiography of the Mediterranean and temperate tropical plains covering an area
of 22,455.28 km². The existing rain stations are 13 rain stations and 9 stations do
not pass the Data Test, the coefficient of the existing Thiessen area is 165.03 km2-
3,758.12 km2, and the daily rainfall correlation is 0.03-0.37. WMO analysis
evaluation resulted in 7 rain stations that met the standard for the area of influence
of 1,000–2,500 km2/station. The Kagan-Rodda method calculates 3 alternatives
with annual cumulative rainfall data for a maximum smoothing error of 5%
resulting in alternative III being relatively better with Z1 of 4.82%, using 11 rain
stations, were maintaining 2 stations, moving 9 stations, and closing 2 stations is
obtained. The area of influence of Thiessen is 1,691.71 km2–2,488.21 km2, the
distance between rain stations is 48.34 km, and all stations meet WMO standards.
While the Kriging method calculates 4 alternatives which results in alternative IV
being relatively better based on the exponential type using 10 rain stations and
closing 3 existing stations, RMSE is 243.35, MAE is 194.92 and all stations meet
WMO standards. The relative error of rainfall in the rationalization design of the
Kagan-Rodda method is relatively better ranging from 9.73% - 34.61% than the
relative error of the Kriging method ranging from 14.48% - 38.17% compared to
the existing condition.
Key words: Rationalization of Density, Rainfall Station, Rokan
