    Pembuatan Pulp Semi Kimia dari Ampas Tebu dengan Ekstrak Abu Tandan Kosong Sawit
    (2013-05-08) Holy, Valiant; Zulfansyah; Iwan Fermi, Muhammad
    In 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.

    Pembuatan Pulp Semi Mekanis dari Batang Jagung dengan Ekstrak Abu Tandan Kosong Sawit
    (2013-05-08) Maulvi Sani, Ikmal; Zulfansyah; Iwan Fermi, Muhammad
    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.

    Potensi Penerapan Gasifikasi Biomassa pada Pabrik CPO
    (2013-05-08) Hermanto; Iwan Fermi, Muhammad; Zulfansyah; Zahrina, Ida
    Indonesia is the world largest palm oil producer with over 23 milion tons of crude palm oil (CPO) production in 2010. About 77% of CPO is exported and the rest is used for domestic consumption. In the palm oil processing, one ton of fresh fruit bunchs can produce 0.23 ton CPO and 0.41 ton of solid waste like empty fruit bunchs, kernel shell and mesocarp fibre. Wheres in plantation, fell trunk, fronds of felling and annual pruning are the the main bio-waste. Some of these fibres and shells are utilized as fuel for mill’s boiler. Biomass energy potentials from palm oil processing were estimated about 83 GW. The objective of this paper is to present the result of study about biomass gasification potential on palm oil mill to generate electricity. The mass heat efficiency and electrical efficiency for biomass gasification were observed were 27.5 % and 25.6 % respectively, and from total biomass were estimated 21 GWe of electricity will be produce. The implementation of biomass gasification in Indonesia will fulfill the electricity demand and reduce the environmental problem in indonesia.
