ANALISIS DAN EVALUASI SALURAN DRAINASE PADA JALAN JAMBORE KELURAHAN CIBUBUR KECAMATAN CIRACAS JAKARTA TIMUR

Abstract

Jalan Jamboree, Cibubur Village, Ciracas District, often experiences puddles during the rainy season. This study
aims to analyze and evaluate whether the dimensions of the drainage channel meet the requirements for runoff
due to rainwater. The case study analysis method uses rainfall data from BMKG which is then carried out
hydrological analysis using the Pearson Log III method, rain intensity analysis using the Mononobe method and
flow discharge analysis using the rational method taking into account the existing water catchment area so that
the actual ditch dimensions can be determined. The evaluation results show that the dimensions of the existing
ditch do not meet the drainage requirements of rainwater runoff, where the existing ditch water discharge
(Qs=0.748 m3/second) < design water discharge (Qt=1.481 m3/second). Second). Re-calculation of channel
dimensions produces the following dimensions: width (b) of 0.9 m, height (h) of 2 m or using precast with width
(b) of 1.2 m and channel height (h) of 1.2 m.
