Abstract

Floods are one of the problems that occur every year, especially in densely populated areas, such as the Dasana Indah Housing Center, Tangerang Regency. The impact of floods can disrupt community activities and cause social, economic and health losses. The purpose of this study was to determine whether the capacity of the drainage channel at Dasana Indah Tangerang Housing could accommodate the amount of design flood for the 5-year return period and find the solution. The data used are secondary data (in the form of rainfall data and catchment area) and primary data (in the form of measuring the dimensions of the existing canal). The analysis of the selected rainfall distribution is Gumbel distribution, rainfall intensity using the Mononobe Method and flood calculations using the Rational Method and channel velocity using the Manning Method. The results of the study obtained, channel 1 (QS1 = 2,081 m3/s < QT1 = 3,231 m3/s); channel 2 (QS2 = 2,161 m3/s < QT2 = 4,331 m3/s); and channel 3 (QS3 = 2,135 m3/s < QT3 = 4,525 m3/s). The solution for flooding in these channels is to re-plan the dimensions, is channel 1 (b1 = 1,712 m, y1 = 0,856 m, w1 = 0,214 m, H1 = 1,070 m); channel 2 (b2 = 2,010 m, y2 = 1,005 m, w2 = 0,251 m, H2 = 1,256 m); and channel 3 (b3 = 1,840 m, y3 = 0,920 m, w3 = 0,230 m, H3 = 1,150 m). And the alternative planning can also be done according to the width, is channel 1 (b1 = 1,400 m, y1 = 1,057 m, w1 = 0,264 m, H1 = 1,321 m); channel 2 (b2 = 1,500 m, y2 = 1,378 m, w2 = 0,345 m, H2 = 1,723 m); and channel 3 (b3 = 1,400 m, y3 = 1,232 m, w3 = 0,308 m, H3 = 1,541 m).

Additional Information:	Banjir menjadi salah satu permasalahan yang terjadi setiap tahunnya terutama pada kawasan padat penduduk, seperti di Perumahan Dasana Indah Kabupaten Tangerang. Dampak banjir dapat mengganggu aktivitas masyarakat dan menimbulkan kerugian sosial, ekonomi serta kesehatan. Tujuan penelitian ini dilakukan untuk mengetahui apakah kapasitas saluran drainase pada Perumahan Dasana Indah Tangerang dapat menampung besaran debit banjir rencana kala ulang 5 tahun dan mendapatkan solusi. Data yang digunakan adalah data sekunder (berupa data curah hujan dan luas daerah tangkapan) dan data primer (berupa pengukuran dimensi saluran eksisting). Analisis distribusi curah hujan yang terpilih adalah Distribusi Gumbel, intensitas curah hujan dengan Metode Mononobe, perhitungan banjir menggunakan Metode Rasional, dan kecepatan saluran dengan Metode Manning. Hasil dari penelitian didapatkan saluran 1 (QS1 = 2,081 m3/s < QT1 = 3,231 m3/s); saluran 2 (QS2 = 2,161 m3/s < QT2 = 4,331 m3/s); dan saluran 3 (QS3 = 2,135 m3/s < QT3 = 4,525 m3/s). Solusi untuk mengatasi masalah banjir pada saluran-saluran tersebut adalah dengan merencanakan ulang dimensi, yaitu saluran 1 (b1 = 1,712 m, y1 = 0,856 m, w1 = 0,214 m, H1 = 1,070 m); saluran 2 (b2 = 2,010 m, y2 = 1,005 m, w2 = 0,251 m, H2 = 1,256 m); dan saluran 3 (b3 = 1,840 m, y3 = 0,920 m, w3 = 0,230 m, H3 = 1,150 m). Juga dapat dilakukan alternatif perencanaan sesuai lebar sealuran yang ada, yaitu saluran 1 (b1 = 1,400 m, y1 = 1,057 m, w1 = 0,264 m, H1 = 1,321 m); saluran 2 (b2 = 1,500 m, y2 = 1,378 m, w2 = 0,345 m, H2 = 1,723 m); dan saluran 3 (b3 = 1,400 m, y3 = 1,232 m, w3 = 0,308 m, H3 = 1,541 m).
