Item Optimasi Pembuatan Pulp Semi-Mekanis Tandan Kosong Sawit: dengan Metode RSM-CCD(2014-02-04) Satria, Rendy; Maulvi Sani, Ikmal; Holy, Valiant; Rionaldo, Hari; Zulfansyah; Amraini, Said ZulPercobaan pembuatan pulp TKS dengan proses semi mekanis dipelajari pada reaktor batch skala laboratorium. Rancangan percobaan RSM-CCD digunakan untuk mempelajari pengaruh konsentrasi NaOH 16, 18 dan 20%, nisbah padatan terhadap cairan 118, 1/10 dan 1112, dan waktu pemasakan 30, 45 dan 60 menit terhadap kualitas pulp. TKS (yield dan kadar lignin). Dari hasil percobaan diperoleh yield pulp 32 - 52% dengan kadar lignin 8 - 23%. Analisis Respone Surface dan Multi-optimisasi untuk mendapatkan kondisi operasi optimum, yang menghasilkan yield pulp maksimum dan. kadar lignin minimum, dilakukan menggunakan bantuan software Minitab (Trial Version). Hasil analisis RSM memperlihatkan bahwa nisbah padatan terhadap cairan memiliki pengaruh yang paling dominan terhadap kualitas pulp, diikuti dengan waktu pemasakan dan konsentrasi NaOH. Kualitas pulp optimum, yaituyield 38% dan kadar lignin 14% . dicapai pada kondisi operasi konsentrasi NaOH 18%, nisbah padatan terbadap cairan 118,0765 dan waktu pemasakan 28,456 menit.Item Pembuatan Pulp Semi Kimia dari Ampas Tebu dengan Ekstrak Abu Tandan Kosong Sawit(2013-05-08) Holy, Valiant; Zulfansyah; Iwan Fermi, MuhammadIn Indonesia, pulp industry has increased in the last two decades. In 1987, the pulp production capacity was only 0.5 million tons and increased to 6.5 million ton in 2007. Until now, 70% of pulp`s raw material came from natural forest. Wood as pulp`s raw material need to be reduced due to environmental concern and its availability continue to decline. Bagasse was lignoselulose which have potential as an alternative resource for pulp. Semi chemical process were pulpmaking process that combining chemical and mechanical process. This research was studied the physical properties of pulp with liquid to solid ratio (8/1, 10/1, and 12/1) and cooking time (2, 3, and 4 hours). The result shows that bagasse pulp have yield of 58.17% - 61.04%, lignin 18.27% - 21.34%. Yield pulp from bagasse has been achieved requirement for semichemical pulp.
