Abstract

Telah dilakukan penelitian pembuatan kertas berbahan baku kertas bekas dengan proses daur ulang. Daur ulang kertas bekas dapat digunakan sebagai solusi pemanfaatan kertas bekas agar dapat mengurangi dampak buruknya terhadap lingkungan. Penelitian ini mengamati pengaruh waktu perendaman, penambahan serat, dan suhu perebusan  terhadap kualitas kertas yang dihasilkan. Jangkauan variabel yang digunakan pada penelitian ini adalah waktu perendaman 8 ,10 ,12 ,14 ,16, 18, dan 20 jam, Penambahan serat dan suhu perebusan 60 ,80 dan 100oC. Hasil kualitas kertas  dianalisa secara gravimetri untuk mendapatkan % ISO Brightness dan Viskositas. Peningkatan waktu perendaman  tidak begitu berpengaruh terhadap % ISO brightness, tetapi berpengaruh terhadap viskositas. Peningkatan suhu perebusan berpengaruh terhadap % ISO brightness dan viskositas. Diperoleh hasil kertas terbaik pada waktu perendaman 20 jam, tidak menggunakan penambahan serat, dan suhu perebusan 100oC.
