Abstract

Pre-treatment of chips rubber wood non-productive as a raw material pulp used hot water and solution NaOH 3-10%, temperature 25-100 °C for 1-2 hours. Has showed a positive influence for quality of pulp if compared with chips without pre-treatment. Result is shown the extractive decreased levels 1 to 1.5 times and lignin content decreased 9-12%. Effect of pre-treatment chips can be increase the pulp yield and Kappa number equal to brightness of pulp. Another effect of chips treatment can be improved to physical properties bleached pulp for tear index, tensile index, folding indurance and brightness if compared with pulp from chips without a treatment. The physical properties pulp of rubber wood with chips pretreatment can produce bleach pulp sulphate have a requirements the quality to SNI Leaf bleach kraft pulp.Keywords : Rubber wood, pre-treatment, sulphate pulp, quality of pulpAbstrakPerlakuan awal serpih kayu karet tidak produktif yang diperuntukan sebagai bahan pulp menggunakan air panas, larutan NaOH 3-10% dan suhu 25-100 oC, selama 1-2 jam. Menunjukkan pengaruh yang positif terhadap kualitas pulpnya dibandingkan dengan pulp yang serpihnya tanpa perlakuan. Hasilnya ditunjukkan oleh menurunnya kadar ekstraktif 1- 1,5 kali dan kadar lignin turun 9-12%. Perlakuan awal serpih dapat meningkatkan rendemen pulp dengan bilangan Kappa setara dengan pulp putihnya. Pengaruh lain dari perlakuan awal serpih kayu karet dapat meningkatkan sifat fisik lembaran pulp sulfat putih terhadap indek sobek, indek tarik, indeks lipat dan kecerahan pulp (derajat putih) dibandingkan dengan kekuatan pulp dari serpih tanpa perlakuan. Sifat fisik pulp kayu karet tidak produktif yang mengalami perlakuan awal serpihnya dapat menghasilkan kualitas pulp sulfat putih yang memenuhi persyaratan SNI pulp sulfat putih kayu daun.Kata kunci : Kayu karet, perlakuan awal, pulp sulfat, kualitas pulp

Abstract

The objective of the study is to examine the influence of 10 l/ ton of Xylanase and Lypase pretreatment on biomechanical pulp of Gmelina and Paracerianthes wood chips with Refiner Mechanical Pulping (RMP) process. The result shows that the enzymatically pretreated of chips can save the electrical consumption of the refiner machine up to 30%, while reducing of 45~50% extractives, and significant improvement of the pulp physical properties compared with control.  Two stages of P1 and P2 hydrogen proxide pulp bleaching produced pulp brightness of  65~71.9 % ISO and more than 97% yield bleached pulp. Physical properties of the tensile index and burst index testing result of Gmelina and Paracerianthes mechanical pulp sheet are fairly good.
