      Abstract
      Air limbah pencelupan industri tekstil mengandung padatan tersuspensi, zat warna, senyawa organik, dan logam berat yang perlu di olah sebelum dibuang ke lingkungan. Penelitian ini bertujuan mengevaluasi efektivitas bottom ash sebagai media filtrasi serta menentukan kondisi aktivasi optimum berdasarkan variasi massa bottom ash, suhu, dan waktu aktivasi. Pengolahan dilakukan menggunakan kolom filtrasi dengan variasi massa bottom ash 500 g, 750 g, dan 1 kg dengan suhu aktivasi 55 °C, 75 °C, 95 °C, dan 105 °C selama waktu aktivasi 30, 60, dan 90 menit. Hasil penelitian menunjukkan bahwa massa bottom ash, suhu aktivasi, waktu aktivasi, dan interaksi ketiganya berpengaruh signifikan terhadap penyisihan padatan tersuspensi total (TSS), warna, dan kebutuhan oksigen kimia (COD) (p=0,05). Kondisi optimum diperoleh pada penggunaan bottom ash 1 kilogram yang diaktivasi pada suhu 105 °C selama 90 menit dengan efisiensi penyisihan TSS, warna, COD, dan kromium total berturut-turut 98,5%; 99,7%; 94,1%; dan 88,2%, sedangkan nilai pH tetap memenuhi baku mutu. Hasil tersebut menunjukkan bahwa potensi bottom ash sebagai media filtrasi alternatif yang efektif dan berkelanjutan untuk pengolahan air limbah pencelupan industri tekstil.
       
      Textile industry dyeing wastewater contains suspended solids, dyes, organic compounds, and heavy metals that require treatment before discharge into the environment. This study aimed to evaluate the effectiveness of bottom ash as a filtration medium and to determine optimal activation conditions based on variations in bottom ash mass, temperature, and activation time. Treatment was conducted using a filtration column with bottom ash masses of 500 g, 750 g, and 1 kg; activation temperatures of 55°C, 75°C, 95°C, and 105°C; and activation times of 30, 60, and 90 minutes. The results indicated that bottom ash mass, activation temperature, activation time, and their interactions significantly influenced the removal of total suspended solids (TSS), color, and chemical oxygen demand (COD) (p=0.05). Optimal conditions were achieved using 1 kg of bottom ash activated at 105°C for 90 minutes, yielding removal efficiencies of 98.5% for TSS, 99.7% for color, 94.1% for COD, and 88.2% for total chromium, while the pH value remained within regulatory standards. These results demonstrate the potential of bottom ash as an effective and sustainable alternative filtration medium for treating textile industry dyeing wastewater.
