Molase merupakan hasil samping pabrik gula yang memiliki kandungan sukrosa yang sudah tidak dapat dikristalkan lagi. Penelitian ini dilakukan menggunakan molase sebagai sumber karbon dan tetrametilamonium klorida sebagai pencetak pori dengan range temperatur karbonisasi pada 500 - 650°C, sedangkan range waktu karbonisasi adalah 30-180 menit. Untuk pengujian adsorptivitas porous carbon hasil variasi waktu digunakan gas benzena. Analisis permukaan dari porous carbon yang dihasilkan dilakukan dengan SEM ( Scanning Electron Microscopy ) untuk mengamati morfologi permukaan dan BET ( Bruanuer Emmet Teller ) untuk mengetahui luas permukaan dan volume pori. Dari hasil penelitian diperoleh porous carbon dengan jumlah dan morfologi molekul yang cenderung meningkat seiring dengan peningkatan temperatur, temperatur optimum diperoleh pada 600°C. Sedangkan waktu karbonisasi dan kemampuan adsorpsi terbaik diperoleh pada waktu 180 menit dengan luas permukaan 265,38 m 2 /gram, volume pori 187,65 x 10 -3 cc/gram dan adsorptivitas sebesar 5,39 x 10 -3 mol/gram.}, issn = {2597-9914}, pages = {93--97} doi = {10.14710/jksa.12.3.93-97}, url = {https://ejournal.undip.ac.id/index.php/ksa/article/view/15559} }
