Abstract

The area of watershed in Krukut River is increasingly fulfilled by the buildings of the House of the population, caused by the increasing number of population. One of The impacts is increased direct surface flow and decreased water quantity that permeating into the soil, resulting in flooding. One of the efforts to deal with this long-term problem is by building reservoirs, situ or bbly at the point where the place is prone to flooding. With the construction of this reservoir is e-xpected to reduce the risk of disaster that will occur, or even negate it altogether. One of the reservoirs in DKI Jakarta province is Brigif Reservoir in Cipedak village, Jagakarsa subdistrict, South Jakarta administrative city. Located right at the meeting with Krukut River or right next to the upstream of Brigif Reservoir. In this study first conducted rain data analysis then conducted flood search. From the results of Perhibenefits known that the Brigif reservoir can reduce or decrease the flood discharge from 66.8865 m3 /s to 37.2559 m3 /s or by 55.70%. Keywords: Krukut River Watershed, Debit flood, Level Pool Routing, Brigif Reservoir, flood discharge. Wilayah DAS kali Krukut semakin hari semakin dipenuhi oleh bangunan-bangunan rumah penduduk yang disebabkan oleh semakin meningkatnya jumlah penduduk. Salah satu dampaknya adalah meningkatnya aliran permukaan langsung dan menurunnya kuantitas air yang meresap ke dalam tanah, sehingga terjadi banjir. Salah satu upaya dalam menangani permasalahan jangka panjang ini adalah dengan membangun waduk, situ ataupun embung di titik dimana tempat tersebut rawan banjir. Dengan dibangunnya waduk ini diharapkan bisa mengurangi resiko bencana yang akan terjadi, atau bahkan meniadakan sama sekali. Salah satu waduk yang ada di Provinsi DKI Jakarta adalah Waduk Brigif yang berada di kelurahan Cipedak, kecamatan Jagakarsa, Kota Administrasi Jakarta Selatan. Berlokasi tepat dipertemuan dengan Kali Krukut atau tepat di sebelah hulu dari Waduk Brigif. Dalam penelitian ini terlebih dahulu dilakukan analisa data hujan kemudian dilakukan penelusuran banjir. Dari hasil perhitungan diketahui bahwa Waduk Brigif dapat mengurangi atau menurunkan debit banjir dari 140.7007 m3 /s menjadi 64.6393 m3 /s atau sebesar 45.941 %. Kata kunci : DAS Kali Krukut, Debit Banjir, Penelusuran Banjir, Waduk Brigif, Debit Banjir.
