“…Dengan proses perebusan, sebagian ikatan hidrogen yang menghubungkan antara lignin, selulosa dan hemiselulosa terputus, sehingga lignin larut dalam air, sedangkan hemiselulosa dan selulosa tetap dalam fase padat (Jasman & Ahmad, 2021). Warna cokelat pada air rebusan menunjukkan bahwa lignin larut dalam air (Pramana et al, 2020). Berbeda halnya dengan perlakuan pengukusan yang memiliki warna cenderung kecokelatan, namun warnanya lebih terang daripada warna serat yang tidak diberi perlakuan apapun.…”

Empthy Fruit Bunches (EFB) is biomass from Palm Oil Mills with high cellulose content. Cellulose can be used for the manufacture of coatings, clothing fibers, bioplastics, papers and membranes. Obtaining pure cellulose for these products generally is begun with the stages of removing the following impurities, through steaming or boiling. This study aims to compare the characteristics of the EFB fiber from the two processes. Comparisons were made by steaming and boiling EFB fiber at 80℃ for 30, 60, 90 and 120 minutes. The fibers was tested for water absorption, density and tensile strength. The test results showed that the boiling process produced brighter colored fibers, tensile strength and water absorption were also better with values of 107.40 kgf/cm2 and 62.46%. Meanwhile, for the density value is is the same for each variation.

“…OPEFB actually has the potential to be utilized because it contains lignocellulose and has not been widely used. However, the presence of OPEFB waste is currently considered to narrow the land so that it is only burned by farmers, and only 10% of the OPEFB has been used for boiler fuel and compost [3]. Lignocellulosic contents including cellulose, hemicellulose, and lignin as well as other substances such as water and extractive substances present in OPEFB can be utilized and processed into chemical added value products.…”

Oil Palm Empty Fruit Bunch (OPEFB) is lignocellulosic biomass waste generated from palm oil processing industries. Due to its significant compositions of cellulose, hemicellulose, and lignin, OPEFB can be further utilized and converted into value-added chemical products which can be used as alternative energy. Hence, the focus of this research is to analyze the effect of microwave pre-treatment (MP) and pressure cooker pre-treatment (PCP) parameters on OPEFB lignin reduction. The treated OPEFB was directly processed using two serial fungal treatment processes. The first fungal treatment process (FT-1) was to maximize the OPEFB lignin removal while the second fungal treatment process (FT-2) was to maximize the glucose production. Combination of microbes such as Phanerochaete chrysosporium, Trichoderma harzianum, Aspergillus niger, and Tricodherma viride was used for both fungal treatment processes. The OPEFB passing 25-mesh screening was used as raw materials. The raw materials mixed with 0.05 w/w NaOH pellets and water to achieve a concentration ratio of 3/50 (w/v) were pre-treated with either MP or PCP. Subsequently, the slurry produced from the pre-treatment process was introduced to FT-1 (P. chrysosporium for 5 days) and finally to FT-2 (T. harzianum, A. niger and T. viride for 4 days). The compositions of lignin, cellulose, hemicellulose, and glucose were analyzed at each process transition and the end of the whole process. It was observed that PCP (60 mins) was the best pre-treatment process with 39.23%-w of lignin removed. On the other hand, combination of MP (150 watts, 60 mins) was followed with FT-1 removed 66.67%-w of lignin. Only around 38.37%-w of lignin was removed when using the whole process, e.g., MP (150 watts, 60 mins), FT-1, and FT-2. The highest composition of glucose, ca. 131.02%-w, was obtained when 40-min PCP followed with FT-1 and FT-2 was applied. The obtained results exhibited that large lignin removal did not necessarily promote high glucose yield in the final product as observed in the 60-min PCP, e.g., P. chrysosporium consumed not only lignin but also presumably hemicellulose and cellulose.
