DESAIN ZERO RUNOFF SYSTEM DI KAMPUS IPB DRAMAGA, BOGOR, JAWA BARAT
ABSTRACT: Bogor Agricultural
University (IPB) Campus is an urban area that experienced flooding when heavy
rain occurred, especially at Graha Widya Wisuda (GWW)’s parking lot, Kamper
Street (FEMA), Meranti Street, and Tanjung Street. The drainage system of IPB
campus is a conventional system. It drain surface runoff as fast as possible to
the outlet. Zero Runoff System (ZROS) is one of technologies to minimize runoff
using water storage. The advantages of ZROS are runoff minimization, local
aquifer’s recharge, and damage mitigation on public facilities. This research
aimed to design ZROS at IPB Campus that capable to minimizesurface runoff. This
research started by water catchment area (WCA) delineation, design rainfall and
peak runoff analysis, infiltration rate measurement, and ZROS design
calculation. Based on frequency analysis the design rainfall was 125.68 mm.
Sub-sub-WCA 1-1C (3 locations), 1-1B, 2-1B, and 2-2A were the flooding’s
location. Water pocket is the proposed technology to be applied in ZROS. To
mitigate flooding, sub-sub-WCA 1-1B, 1-1C, 2-1B, and 2-2A needed 44 units of
water pockets with length of 1.20 m (sub-subDTA 1-1B, 2-1B, dan 2-2A) and 1.60
m (sub-sub-DTA 1-1C), with depth ranged from 2.41 m to 3.40 m.
