      Abstract
      Indonesia telah mengalami lonjakan produksi batu bara, namun menghadapi tantangan dengan air asam tambang (AAT) dari operasi pertambangan. Air asam tambang mengandung unsur-unsur logam berat terlarut yang tinggi dikarenakan pH air yang sangat rendah. Oleh karena itu, untuk mencegah pencemaran perairan umum yang diakibatkan oleh AAT, maka pemerintah mewajibkan perusahaan tambang untuk mengelola AAT sebelum dilepaskan ke perairan umum. Penelitian ini bertujuan menganalisis berbagai komposisi fly ash dan bottom ash (FABA) dalam pembuatan batu bata untuk menentukan keefektifannya dalam menaikkan pH AAT serta membandingkan efisiensi penggunaan batu bata FABA dengan tanaman dalam menaikkan pH AAT. Penelitian dilakukan di PT Pesona Khatulistiwa Nusantara dari bulan Maret hingga Juni 2023 dengan menggunakan metode Rancangan Acak Lengkap satu faktor dengan enam perlakuan dan tiga kali ulangan. Hasil penelitian menunjukkan bahwa komposisi FABA berpengaruh pada kemampuan batu bata FABA menaikkan pH AAT. Komposisi FABA terbaik yaitu fly ash = 60% dan bottom ash = 20%. Tanaman memerlukan waktu lebih lama dalam menaikkan pH AAT.
       
      Indonesia has experienced a surge in coal production, but faces challenges with acid mine drainage (AMD) from mining operations. AMD contains high levels of dissolved heavy metal elements due to the very low pH of the water. Therefore, to prevent pollution of public waters caused by AMD, the government requires mining companies to treat AMD before it is released into public waters. This study aims to analyze various compositions of fly ash and bottom ash (FABA) in brick making to determine their effectiveness in raising the pH of AMD and to compare the efficiency of using FABA bricks with plants in raising the pH of AMD. The research was conducted at PT Pesona Khatulistiwa Nusantara from March to June 2023 using a one-factor Completely Randomized Design method with six treatments and three replications. The results showed that the composition of FABA affects the ability of FABA bricks to raise the pH of AMD. The best FABA composition is fly ash = 60% and bottom ash = 20%. Plants require longer time in raising the pH of AMD.
