    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 Zul
    Percobaan 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.

    Indonesia was ranked ninth producers to supplied the pulp industry. Wood still used as the main raw materials with natural wood supply more than 70%. The pulp industry worldwide always faced a problem on lack of raw material due to deforestation. Corn stalks is an alternative source of non wood fiber for making pulp. This research was investigated the influence variable process with chemi-mechanical pulping of corn stalk toward pulp properties. The variable process were used solid to liquor ratio (8/1; 10/1; and 12/1) and cooking time (2 hour; 3 hour; and 4 hour). The pulping of corn stalk was accelerated in batch reactor with normal boiling temperature. The results showed pulp with yield 53,43 - 58,50%.and lignin 11,35 - 13,91%.. The influence of variable process on the pulp properties was significant. The increased variable process were caused decreased of yield and Indonesia was ranked ninth producers to supplied the pulp industry.
