ABSTRAK
Urbanisasi telah mengubah tutupan lahan dari permukaan lolos air menjadi permukaan
kedap air yang dapat berdampak pada peningkatan limpasan hujan di kawasan
perkotaan. Penelitian ini bertujuan untuk menilai efektifitas sebaran spasial Green
Infrastructure (GI) dalam pengurangan limpasan hujan di berbagai spektrum hujan.
Simulasi pengurangan limpasan hujan melalui penerapan GI diimplementasikan pada
DTA yang berlokasi di Pondok Kelapa, Duren Sawit, Jakarta Timur. EPA SWMM
digunakan untuk mensimulasi model hidrologi melalui tiga skenario : skenario-1
baseline (kondisi eksisting tanpa penerapan GI), skenario-2 GI (penerapan GI melalui
rain garden, rain barrel dan porous pavement), skenario-3 RDTR (sesuai Rencana
Detail Tata Ruang DKI Jakarta). Hasil simulasi SWMM menunjukkan skenario-2 GI
untuk hujan kala ulang 2-, 5-, 10-, 25-, 50-tahun menghasilkan persentase pengurangan
total volume limpasan secara berurutan sebesar 9.76%, 8.76%, 8.27%, 7.50%, 7.05%
dan persentase pengurangan debit puncak sebesar 9.29%, 7.97%, 5.83%, 3.49%, 2.21%
dibandingkan tanpa penerapan GI. Adapun untuk skenario-3 RDTR untuk kala ulang
hujan yang sama menghasilkan persentase penambahan total volume limpasan secara
berurutan sebesar 7.43%, 6.15%, 5.36%, 4.67%, 4.20% dan persentase penambahan
debit puncak sebesar 3.93%, 2.33%, 1.29%, 0.63%, 0.63% dibandingkan dengan
kondisi eksisting tanpa penerapan GI.

ABSTRACT
Urbanization has changed the land use from pervious cover to impervious cover which
have an impact on increasing runoff in urban areas. The objective of this study is to
determine the effectiveness of spatial distribution of Green Infrastructure (GI) in
reducing runoff under various design storms. Simulation of runoff reduction is carried
out by implementing the GI in the catchment area located in Pondok Kelapa, Eastern
Jakarta, Indonesia. EPA SWMM 5.1 was used to simulate the performance of GI on
reducing runoff in the study site for three simulation scenarios: baseline scenario
(current conditions), GI scenario (implementing rain garden and rain barrel) and
Rencana Detail Tata Ruang (RDTR) scenario. The results show that GI scenario
compared to the baseline scenario under various design storms 2-year, 5-year, 10-year,
25-year and 50-year return periods reduce the total runoff volume approximately 9.76%,
8.76%, 8.27%, 7.50%, 7.05, respectively and reduce the peak flows approximately
9.29%, 7.97%, 5.83%, 3.49%, 2.21%. For RDTR scenario compared to BL scenario
resulting in percentile of total runoff volumes increase were 7.43%, 6.15%, 5.36%,
4.67%, 4.20% and the percentile of peak flows increase were 3.93%, 2.33%, 1.29%,
0.63%, 0.63% for the same return periods.
