ANALISIS PERBANDINGAN PENGGUNAAN METODE ARITMATIKA, POLIGON THIESSEN DAN ISOHYET DALAM PERHITUNGAN CURAH HUJAN RERATA DAERAH (Studi Lokasi DAS Jangkok)
Indonesia is a country that has two seasons, the dry season and the rainy season. One of the important things about the existence of those seasons is rainfall. To obtain the results of hydrological analysis, an input of calculation of regional average rainfall is required. So, from the hydrology analysis can be used to conduct analysis of civil works, especially the field of irrigation. The study aims to determine which method is best in the calculation of the regional average rainfall. This research was conducted by calculating the regional average rainfall and runoff depth then comparing the level of the relationship between the results of the regional average rainfall calculation using the Arithmetic, Polygon Thiessen and Isohyet methods on the calculation of runoff depth. The results show that the calculation of regional average rainfall using the Thissen Polygon method yields the largest average value of 91.48 mm, while the Isohyet method is the most accurate way of calculating the average regional rainfall in the Jangkok Watershed with a correlation coefficient of 0.712
