Suatu proses untuk mengubah data hujan ke limpasan atau aliran debit disebut dengan proses transformasi hujan. Transformasi hujan menjadi debit ini dipengaruhi oleh karakteristik fisik DAS serta penggunaan lahannya. Data debit pada suatu DAS berfungsi sebagai pengukur besaran debit yang tersedia pada suatu sungai yang bermanfaat dalam meningkatkan pengelolaan Sumber Daya Air. Studi ini bertujuan untuk mengetahui hasil perhitungan hujan menjadi debit berlokasi di DAS Metro, Kabupaten Malang. Metoda yang dianalisa oleh peneliti adalah metoda FJ. Mock dan NRECA. Hasil perhitungan dari metode-metode tersebut kemudian dibandingkan dengan data hujan, dikarenakan data AWLR pada Sub DAS Metro ini dianggap kurang layak untuk menjadi debit observasi dalam studi ini. Berdasarkan hasil analisis metode yang paling sesuai untuk perhitungan debit hujan pada Sub DAS Metro adalah metode NRECA dengan nilai Koefisien Determinasi (R 2 ) = 0,792 serta Koefisien Korelasi (r) = 0,887.

This study aimed to analyze drought conditions and evaluate irrigation water availability and household water needs in the Krueng Jrue sub-watershed, Aceh Province, Indonesia. The Z-score statistics method was developed to analyze the drought, and the Mock model was used to generate discharges. We performed model validation using linear regression, which produced a coefficient of determination (R2 = 0.90**) and coefficient of regression (r = 0.95**). In general, this area had a normal Z-score for precipitation (ZSP) class with 90 events (75%) and a normal Z-score for a discharge (ZSD) class with 89 events (74.2%). There were 0–11 (0–9.2%) moderate wet, very wet, extreme wet, moderate drought, and severe drought events. The consistency between the ZSP and ZSD indices reached 85.8%, indicating consensus between the meteorological droughts that were analyzed based on rainfall (ZSP) and hydrological droughts analyzed based on water discharge (ZSD). ZSP and ZSD indices showed negative values during the dry season (April to September) and positive values during the rainy season (October to March). There was a surplus of water availability for irrigation and household water needs during the rainy season and a deficit during the dry season. However, water deficits also occurred in certain months during the rainy rendeng planting season, for example, in October 2009, 2013, 2016, and 2017 as well as in February between 2008 to 2011 and from 2014 to 2017. This observation was probably due to the influence of global climate variables that need to be substantiated. This study offers necessary information for farmers, the community, and the local government when anticipating drought phenomenon, organizing the rice planting season, and evaluating water availability in other watersheds.
