“…This was comparable with the chemical components reported by other researchers [3,5,[7][8], except for the hemicellulose content which was higher than that in the three reports [3,5,7], but almost the same as that reported by Goh et al [8]. The change of these chemical components in OPF after pretreatment using P. chrysosporium and T. versicolor is presented in Table 1.…”

Oil palm frond is one type of lignocellulosic biomass abundantly and daily available in Indonesia. It contains cellulose which can be converted to glucose, and further processed to produce different kinds of value -added products. The aim of this research is to study the effects of biological pretreatment of oil palm frond (OPF) fiber using Phanerochaete chrysosporium and Trametes versicolor on the enzymatic saccharification of the biomass. The OPF fiber (40-60 mesh sizes) was inoculated with cultures of the two fungi and incubated at 27 °C for 4 weeks. The samples were taken after 1, 2, 3, and 4 weeks of incubation. Chemical components of the biomass after pretreatment were analyzed. The saccharification of the pretreated samples using cellulase and β-glucosidase was performed in a water bath shaker at 50 °C for 48 hours. The concentration of reducing sugar increased with increasing of incubation time, either in those pretreated with culture of P. chrysosporium or with T. versicolor. Pretreatment of OPF fiber using single culture of T. versicolor for 4 weeks gave the highest reducing sugar yield (12.61% of dry biomass). AbstrakPretreatment Biologis Serat Pelepah Kelapa Sawit Menggunakan Jamur Pelapuk Putih untuk Sakarifikasi Enzimatis. Pelepah kelapa sawit (PKS) merupakan salah satu biomassa lignoselulosa yang tersedia cukup melimpah di Indonesia. Serat PKS mengandung selulosa yang dapat dikonversi menjadi glukosa, dan selanjutnya dapat diproses lebih lanjut untuk menghasilkan berbagai produk yang mempunyai nilai tambah. Tujuan penelitian ini adalah untuk mempelajari pengaruh pretreatment biologis pada serat PKS menggunakan Phanerochaete chrysosporium dan Trametes versicolor terhadap hasil sakarifikasinya. Serat PKS (40-60 mesh) diinokulasi dengan kedua kultur jamur dan diinkubasi pada suhu 27 °C selama 4 minggu. Contoh diambil setelah masa inkubasi selama 1, 2, 3, dan 4 minggu dan dianalisis kandungan komponen kimianya. Sakarifikasi PKS yang telah diberi pretreatment menggunakan selulase 20 FPU/g substrat dan β-glukosidase 14 CBU/g substrat dilakukan dalam water bath shaker pada suhu 50 °C selama 48 jam. Konsentrasi gula pereduksi meningkat dengan semakin lamanya waktu inkubasi, baik pada contoh dengan perlakuan P. chrysosporium maupun dengan T. versicolor. Pretreatment serat PKS menggunakan kultur tunggal T. versicolor selama 4 minggu menghasilkan rendemen gula pereduksi tertinggi (12,61% dari berat kering biomassa).

“…This amount of biomass has the potential to be utilized as raw material of some value added products. There are some studies regarding the use of OPF, as a mixture for ruminants feed [2], for pulp [3], and for making compost [4]. Another potential use of OPF is for production of bioethanol.…”

“…2% for the EFB material, whereas it was only about 0.2% in the case of the hardwood. It has been reported that lower reject percentages can be achieved by varying the EFB cooking conditions [5], such as by increasing the cooking temperature and the amount of active alkali. The kappa number for the EFB pulp under the present cooking conditions was as low as that of the hardwood pulp, thus it appears that EFB can be delignificated to the same degree as hardwood by a suitable choice of cooking method and conditions.…”

The basic properties of paper produced from EFB pulp have also been studied [5]. In addition, mixing of EFB pulp with hardwood pulp and the use of EFB pulp as a recycled paper strengthening agent have been proposed [6][7] .…”

The effects of various carbonization parameters on the COD reduction of Rhodamine B dye aqueous solutions using carbonized Elaeis guineensis frond fiber (EGFF) chars have been studied experimentally. The adsorbent with the particle size of <45 µm has been carbonized at temperature from 500-900 o C with carbonization duration of 1-3 h at a heating rate of 10-30 o C/min and nitrogen gas flow rate of 100-500 cm 3 /min. Carbonization temperature, carbonization duration, heating rate and nitrogen gas flow rate were significantly affecting the carbonization process. Statistical analysisresponse surface methodology (RSM)-face centered composite design (FCCD) was used to obtain the optimal carbonization conditions. The optimum condition for carbonization of EGFF was obtained at carbonization temperature of 899 o C, carbonization duration of 2.7 h, heating rate of 10 o C/min, and nitrogen flow rate of 243 cm3/min with 98.88 % of COD reduction of Rhodamine B
