      Abstract
      Pencemaran air oleh minyak bumi merupakan permasalahan lingkungan yang berdampak serius terhadap ekosistem perairan. Fitoremediasi menjadi metode alternatif yang ramah lingkungan untuk menangani pencemaran tersebut. Proyek ini bertujuan mengevaluasi pengaruh penambahan Bio-Oil Spill Dispersant (OSD) terhadap efektivitas Ipomoea aquatica sebagai agen fitoremediasi dalam sistem constructed wetland skala pilot. Pengujian awal menunjukkan bahwa Ipomoea aquatica mampu bertahan terhadap efek toksik surfaktan, dengan waktu tinggal optimal selama 4 hari pada rasio dispersant terhadap minyak (Dispersant to Oil Ratio/DOR) sebesar 0,5:1. Desain tersebut kemudian diterapkan secara kontinu dan menghasilkan penurunan konsentrasi COD hingga 160 mg/L, BOD sebesar 40,82 mg/L, serta TPH sebesar 0,120 mg/L, meskipun nilai DO yang dihasilkan tergolong rendah yaitu 2,42 mg/L. Kombinasi perlakuan fitoremediasi dengan penambahan Bio-OSD pada rasio DOR 0,5:1 terbukti menurunkan kadar polutan secara signifikan, meskipun berdampak pada pertumbuhan morfologi Ipomoea aquatica Kata kunci: constructed wetland, bio-Oil Spill Dispersant, fitoremediasi, Ipomoea aquatica, minyak bumi.
       
      Oil pollution in water is a serious environmental issue that adversely affects aquatic ecosystems. Phytoremediation offers an eco-friendly alternative method for addressing such contamination. This project aimed to evaluate the effect of adding Bio-Oil Spill Dispersant (OSD) on the effectiveness of Ipomoea aquatica as a phytoremediation agent in a pilot-scale constructed wetland system. Initial tests showed that Ipomoea aquatica was able to withstand the toxic effects of surfactants, with an optimal retention time of 4 days at a Dispersant to Oil Ratio (DOR) of 0.5:1. This design was then applied in a continuous system and resulted in reductions in COD concentration to 160 mg/L, BOD to 40.82 mg/L, and TPH to 0.120 mg/L, although the resulting DO level was relatively low at 2.42 mg/L. The combination of phytoremediation treatment with Bio-OSD at a DOR of 0.5:1 effectively reduced pollutant levels, although it had an impact on the morphological growth of Ipomoea aquatica.
