      Abstract
      Green roof adalah solusi yang layak untuk mengurangi peningkatan volume limpasan di daerah perkotaan. Sebagai komponen utama green roof, vegetasi dapat memberikan dampak yang signifikan terhadap kuantitas dan kualitas air limpasan. Penelitian ini menganalisis kualitas dan kuantitas air hujan serta air limpasan dari 4 sistem green roof yang ditanami lili paris (CC), kacang hias (AP), krokot mawar (PG), dan substrat tanpa vegetasi (UV) sebagai kontrol. Berdasarkan 10 kejadian hujan, rata-rata retensi untuk green roof CC, AP, PG dan UV secara berurutan adalah 21,1%; 37,6%; 50,3%; dan 52,7%. Curah hujan dan limpasan green roof dianalisis untuk mengetahui nilai parameter kualitas air, yaitu suhu, TDS, pH, DO, BOD, COD, nitrit, dan amonia. Baku mutu yang digunakan mengacu pada Permenkes No. 2 Tahun 2023 dan PP No. 22 Tahun 2021 Lampiran VI. Hasil pengujian menghasilkan status mutu air hujan berdasarkan US-EPA adalah Cemar Sedang (PP) dan Cemar Ringan (Permenkes). Jenis vegetasi dapat mempengaruhi kualitas air limpasan green roof. Vegetasi terbaik untuk green roof yaitu krokot mawar. Teknologi lanjutan peningkatan kualitas air limpasan yang paling optimal yaitu zeolit filter dan MNBs.
       
      Green roofs are a viable solution to reduce the increasing volume of runoff in urban areas. As a major component of green roofs, vegetation can have a significant impact on runoff water quantity and quality. This study analyzed the quality and quantity of stormwater and runoff water from 4 green roof systems planted with paris lilies (CC), ornamental beans (AP), rose purslane (PG), and a substrate without vegetation (UV) as a control. Based on 10 rainfall events, the average retention for CC, AP, PG and UV green roofs were 21,1%; 37,6%; 50,3%; dan 52,7%, respectively. Rainfall and green roof runoff were analyzed to determine the value of water quality parameters, namely temperature, TDS, pH, DO, BOD, COD, nitrite, and ammonia. The quality standard used refers to Permenkes No. 2 Tahun 2023 dan PP No. 22 Tahun 2021 Lampiran VI.The test results resulted in the quality status of rainwater based on US-EPA is Moderately Polluted (PP) and Lightly Polluted (Permenkes). Vegetation types can affect the quality of green roof runoff water. The most optimal advanced runoff water quality improvement technologies are zeolite filters and MNBs.
