<![CDATA[ABSTRAK Penelitian ini bertujuan untuk mengetahui efektivitas fitoremediasi menggunakan tanaman Lili Paris (Chlorophytum comosum) dan Peace Lily (Spathiphyllum wallisii) dalam menurunkan kadar pencemar pada air limbah IPAL Komunal Kampung Batik Laweyan. Penelitian dilakukan dengan variasi komposisi tanaman 250:0, 200:100, 150:150, 100:200, dan 0:250 gram pada volume limbah 5 liter. Pengamatan dilakukan selama 10 hari dengan pengujian parameter COD, TDS, pH, dan intensitas warna pada hari ke-1, 3, 5, 7, dan 10. Hasil penelitian menunjukkan bahwa proses fitoremediasi mampu menurunkan seluruh parameter pencemar yang diuji. Nilai COD awal sebesar 942,0561 mg/L menurun dengan efisiensi tertinggi sebesar 86,67% pada komposisi 150 g Lili Paris dan 150 g Peace Lily. Nilai TDS awal sebesar 5,341 g/L mengalami penurunan hingga mencapai efisiensi sebesar 93,30%. Parameter pH yang semula berada pada kondisi basa mengalami penurunan hingga mendekati netral pada akhir pengamatan. Selain itu, intensitas warna limbah yang diukur menggunakan spektrofotometer UV-Vis mengalami penurunan absorbansi dari 1,055 menjadi 0,763981 dengan efisiensi penyisihan warna sebesar 27,58%. Berdasarkan hasil penelitian dapat disimpulkan bahwa kombinasi tanaman Lili Paris (Chlorophytum comosum) dan Peace Lily (Spathiphyllum wallisii) efektif digunakan sebagai agen fitoremediasi untuk memperbaiki kualitas air limbah batik. Komposisi tanaman 150 g : 150 g memberikan hasil terbaik dalam menurunkan kadar pencemar sehingga berpotensi diterapkan sebagai metode pengolahan limbah yang sederhana, ekonomis, dan ramah lingkungan. ABSTRACT This study aims to determine the effectiveness of phytoremediation using the Paris Lily (Chlorophytum comosum) and Peace Lily (Spathiphyllum wallisii) plants in reducing pollutant levels in the wastewater of the Laweyan Batik Village Communal Wastewater Treatment Plant. The study was conducted with variations in plant composition of 250:0, 200:100, 150:150, 100:200, and 0:250 grams in a waste volume of 5 liters. Observations were made for 10 days by testing the parameters of COD, TDS, pH, and color intensity on days 1, 3, 5, 7, and 10. The results showed that the phytoremediation process was able to reduce all pollutant parameters tested. The initial COD value of 942.0561 mg/L decreased with the highest efficiency of 86.67% in the composition of 150 g of Paris Lily and 150 g of Peace Lily. The initial TDS value of 5.341 g/L decreased to an efficiency of 93.30%. The pH parameter, which was initially alkaline, decreased to near neutral at the end of the observation. Furthermore, the color intensity of the wastewater measured using a UV-Vis spectrophotometer decreased in absorbance from 1.055 to 0.763981, with a color removal efficiency of 27.58%. Based on the results of the study, it can be concluded that the combination of the Spider Lily (Chlorophytum comosum) and the Peace Lily (Spathiphyllum wallisii) plants is effective as a phytoremediation agent to improve the quality of batik wastewater. The 150 g:150 g plant composition provided the best results in reducing pollutant levels, thus potentially being applied as a simple, economical, and environmentally friendly wastewater treatment method.]]>
