Hujan rencana dengan menggunakan analisis frekuensi regional memberikan keuntungan pada sekelompok data yang memiliki jumlah data terbatas. Data minimal yang digunakan dalam menghitung besarnya hujan rencana memiliki tingkat kesalahan yang sangat besar untuk hujan rencana pada periode yang sangat tinggi. Oleh karena itu, maka digunakan analisis frekuensi regional berdasarkan pendekatan TL-momen. Jenis distribusi yang digunakan terdiri dari tiga yaitu Generalized Extreme Value (GEV), Generalized Pareto (GPA) dan Generalized Logistic (GLO). Dari ketiga jenis distribusi yang digunakan hanya Generalized Extreme Value (GEV) dan Generalized Logistic (GLO) yang mendekati nilai rata-rata regionalnya berdasarkan TL-Moment Ratio sementara berdasarkan hasil pengujian Z distribusi menunjukkan Generalized Extreme Value (GEV) memberikan hasil yang terbaik. Dengan demikian, maka hujan rencana yang dihitung berdasarkan analisis frekuensi regional di DAS Jakarta menggunakan Generalized Extreme Value (GEV) telah dapat ditentukan.

Payakumbuh a small town with a self government is the capital of Kabupaten Limapuluh Kota - WestSumatera. About 60 % of the land area is being used for agriculture and consequently water demand is veryhigh. With the growth of population and its social and economic condition, the reguirement for water has alsoincreased.In anticipating the problem, concern is be given to the development and management of water resources.Particulary to the two water sources passing the region, i.e. the Batang Agam and Batang Lampasi. A weircan be developed in the Batang Agam at Padang Ambacang, whereas river storage structures can bedeveloped, such as dams, long storages and water wheels, in the Batang Lampasi. In addition to developingthe water system, paddy production can be inereased by applying the System of Rice Intensification (SRI).
