"Urbanisasi Jakarta telah mengurangi fungsi hidrologi, memicu banjir musiman dengan peningkatan area terbangun 51%, ruang hijau berkurang menjadi 5%, serta perubahan iklim yang mengintensifkan suhu (27-30°C) dan curah hujan 12%, sementara drainase konvensional yang hanya mampu menangani 50-70mm/hari gagal saat kejadian ekstrem menyebabkan banjir ketika curah hujan melebihi 92mm/hari. Penulisan ini mengkaji sistem swale sebagai Nature-Based Solutions untuk pengelolaan air hujan perkotaan dalam konteks Jakarta. Tulisan ini menerapkan prinsip National Association of City Transportation Officials (NACTO) Urban Street Stormwater Guide yang berfokus pada perlindungan sumber daya alam, desain resiliensi, dan optimasi kinerja, serta teori Active, Beautiful, Clean Waters Singapura yang menekankan integrasi ruang biru-hijau-komunitas. Penelitian mengkaji karakteristik ini melalui tinjauan literatur dan analisis komparatif tiga studi kasus: implementasi bioswale di Palmerah Timur, desain standard swale di Pulau Tengah, dan aplikasi wet swale di Tebet Ecopark. Hasil menunjukkan swale mencapai reduksi limpasan 1-88% dengan kemampuan penyisihan polutan signifikan. Komponen rekayasa mencakup media tanah, check dams, underdrains, dan vegetasi lokal untuk mengoptimalkan kinerja dalam kondisi permeabilitas rendah Jakarta, namun memerlukan integrasi holistik dengan nature-based solutions lainnya untuk memaksimalkan potensi NBS secara keseluruhan.

Jakarta's urbanization has degraded hydrological functions, triggering seasonal flooding with built-up areas increasing 51%, green spaces reduced to 5%, climate change intensifying through rising temperatures (27-30°C) and 12% increased precipitation, while conventional drainage handling only 50-70mm/day fails during extreme events causing floods when rainfall exceeds 92mm/day. This study examines swale systems as Nature-Based Solutions for urban stormwater management in Jakarta's context. The research applies National Association of City Transportation Officials (NACTO) Urban Street Stormwater Guide principles focusing on natural resource protection, resilience design, and performance optimization, alongside Singapore's Active, Beautiful, Clean Waters theory emphasizing integrated blue-green-community spaces. This study examines these characteristics through literature review and comparative analysis of three case studies: bioswale implementation in Palmerah Timur, standard swale design in Pulau Tengah, and wet swale application in Tebet Ecopark, evaluating swale design performance across different urban implementation scales. Results demonstrate swales achieve 1-88% runoff reduction with significant pollutant removal capabilities. Engineered components including soil media, checkdams, underdrains, and indigenous vegetation optimize performance within Jakarta's low-permeability conditions. However, swales cannot be implemented as standalone systems but require holistic integration with other nature-based solutions to channel or retain runoff before entering conventional urban drainage, maximizing overall nature based solution (NBS) potential. Within smaller urban contexts such as residential areas, swale design adaptability presents particular architectural significance through their flexible construction methodology and implementation approach, enabling community-level sustainable stormwater management while fostering local engagement in urban environmental solutions."
