Abstract

Flood mitigation of Situ Pondok Jagung caused by it’s inadequate capacity to handle water, resulting in overflow and localized inundation, this study employed an analytical and simulation modeling approach using SWMM 5.1 software. The modeling process required input data such as Rain Gage, Subctachment, Conduit, Juction, Storage Unit, and Outfall. The analysis and modeling revealed a capacity shortfall, evident from the floodwater levels observed in Situ Pondok Jagung. The analysis and modeling results indicate an excess capacity of the storage capacity, as evidenced by the flood water elevation in Situ Pondok Jagung. Thus, the hydraulic analysis in SWMM 5.1 considers two design conditions: the existing condition with a height of 1.5m, showing a total water discharge of 103,75 m3/s, and a storage volume of 119.250 m2. For the planned condition using trial and error experiment, dredging was performed to a depth of 20cm, and an additional 50cm in height was added to the levee. As a result, the height of Situ Pondok Jagung became 2,2m, with zero overflow, and a storage volume of 174.900 m3. This represents a reduction of 40% and indicates that this planning effort could be considered as an alternative solution.

Abstract

Penelitian ini dilakukan berdasarkan keresahan warga Perumahan Graha Bunga yang selalu dilanda banjir akibat hujan lebat. Penelitian ini bertujuan untuk memberikan solusi dalam penanggulangan banjir yang terjadi di Perumahan Graha Bunga dengan percobaan pemasangan pompa dan pintu air yang di keluarkan melalui pompa dan pintu air. Data-data yang dibutuhkan dalam penelitian ini adalah data curah hujan, mencari elevasi saluran drainase menggunakan Google Earth,saluran drainase, kapasitas pompa dan ukuran pintu air. Untuk mendapatkan curah hujan perjam dilakukan perhitungan dengan rumus mononobe. Hasil simulasi yang peneliti telah lakukan menyatakan bahwa pintu air dan pompa mampu untuk menanggulangi banjir di Perumahan Graha Bunga. Kesimpulannya adalah pemasangan pompa dan pintu air diperlukan untuk mengatasi permasalahan banjir di Perumahan Graha Bunga tersebut.
