Abstract

Asam borat dengan rumus kimia H₃BO₃ merupakan bahan kimia padatan dari bahan baku boraks (Na₂B₄O₇·10H₂O) dan asam sulfat (H₂SO₄) melalui reaksi asidifikasi. Asam borat merupakan senyawa kimia yang banyak digunakan dalam industri kaca, keramik, pupuk, serta bahan baku antiseptik dan kosmetik. Proses produksi asam borat melibatkan reaksi antara boraks dan asam sulfat dalam Reaktor Alir Tangki Berpengaduk (RATB) pada kondisi temperatur 100℃ terkendali untuk menghasilkan asam borat dan produk samping berupa natrium sulfat (Na₂SO₄). Pemisahan dilakukan melalui kristalisasi, filtrasi, dan pengeringan. Pabrik direncanakan beroperasi secara kontinu 24 jam per hari selama 330 hari per tahun. Pendirian pabrik direncanakan di Kawasan Industri JIIPE, Kabupaten Gresik, Provinsi Jawa Timur dengan produksi pertama di tahun 2031. Pabrik asam borat ini ditargetkan memiliki kapasitas 8.000 ton per tahun, yang diharapkan dapat memenuhi kebutuhan domestik dan mengurangi ketergantungan impor, menjadikannya pabrik asam borat pertama di Indonesia. Kajian ekonomi dari pabrik asam borat ini dengan total modal investasi (TCI) yakni sebesar $3.048.172,50, didapatkan hasil analisis profitabilitas ROI sebesar 78%, BEP 70%, DCFR 39%, SDP 30%, DPBP 2 tahun, dan NPV $14.753.546,33 menunjukkan bahwa proyek ini layak untuk ditinjau kembali.
