“…Akan tetapi, TKKS dapat digunakan sebagai bahan baku fermentasi untuk menghasilkan berbagai produk bernilai dikarenakan jumlahnya sangat melimpah dan murah [6]. Salah satu bioproduk yang paling umum yang dapat dikonversi dari TKKS adalah bioetanol [7]. 156 TKKS merupakan biomassa lignoselulosa yang terdiri dari fraksi selulosa, hemiselulosa dan lignin.…”

Indonesia sebagai negara penghasil minyak kelapa sawit terbesar di dunia memiliki limbah tandan kosong kelapa sawit (TKKS) yang melimpah. TKKS ini dapat dikonversi menjadi berbagai bioproduk yang didahului dengan proses pretreatment. Pada penelitian ini akan diteliti perhitungan panas pretreatment TKKS dengan sodium hidroksida dan asam fosfat pada kondisi suhu rendah. Hasil penelitian menunjukkan bahwa panas pretreatment dengan menggunakan sodium hidroksida lebih tinggi dibandingkan dengan panas pretreatment dengan asam fosfat. Selain itu, berdasarkan variasi konsentrasi asam fosfat yang digunakan, semakin tinggi konsentrasi asam fosfat membuat panas pretreatment dengan menggunakan larutan asam fosfat semakin rendah. Perbedaan nilai panas pada pretreatment dengan menggunakan sodium hidroksida dan asam fosfat dipengaruhi oleh panas pembentukan dari masing-masing senyawa yang digunakan proses pretreatment. Panas pretreatment TKKS dengan 5% larutan sodium hidroksida menghasilkan panas sebesar 125 kJ. Sedangkan, panas pretreatment dengan menggunakan asam fosfat pada berbagai konsentrasi 70%, 75%, 80% dan 85% adalah 117 kJ, 103 kJ, 88 kJ dan 74 kJ.Indonesia as the largest palm oil producing country in the world has abundant oil palm empty fruit bunches (OPEFBs). OPEFBs can be converted into various bioproducts which are preceded by pretreatment process. This research investigated the heat calculation of OPEFBs pretreatment with sodium hydroxide and phosphoric acid at low temperature conditions. The results showed that the heat using sodium hydroxide was higher than the heat using phosphoric acid. In addition, based on variation in phosphoric acid concentrations used, it was found that the higher concentration of phosphoric acid made the heat of phosphoric acid pretreatment became lower. The difference of heat value in sodium hydroxide and phosphoric acid pretreatment was influenced by the heat of formation in each compound used in the pretreatment process. Heat pretreatment of OPEFBs with 5% sodium hydroxide solution was 125 kJ. While, heat pretreatment using phosphoric acid at various concentrations of 70%, 75%, 80% and 85% were 117 kJ, 103 kJ, 88 kJ and 74 kJ.

“…Many studies reported the potential use of OPEFB as the feedstock of bioethanol production due to its high cellulose content [ 7 , 23 , 24 , 25 ]. Saccharomyces cerevisiae is the most commonly employed yeast for commercial ethanol production, although various yeasts, bacteria, and other microorganisms can produce ethanol [ 26 , 27 ].…”

An Integrated Process for the Xylitol and Ethanol Production from Oil Palm Empty Fruit Bunch (OPEFB) Using Debaryomyces hansenii and Saccharomyces cerevisiae

et al. 2022

Oil palm empty fruit bunch (OPEFB) is the largest biomass waste from the palm oil industry. The OPEFB has a lignocellulose content of 34.77% cellulose, 22.55% hemicellulose, and 10.58% lignin. Therefore, this material’s hemicellulose and cellulose content have a high potential for xylitol and ethanol production, respectively. This study investigated the integrated microaerobic xylitol production by Debaryomyces hansenii and anaerobic ethanol semi simultaneous saccharification and fermentation (semi-SSF) by Saccharomyces cerevisiae using the same OPEFB material. A maximum xylitol concentration of 2.86 g/L was obtained with a yield of 0.297 g/gxylose. After 96 h of anaerobic fermentation, the maximum ethanol concentration was 6.48 g/L, corresponding to 71.38% of the theoretical ethanol yield. Significant morphological changes occurred in the OPEFB after hydrolysis and xylitol and ethanol fermentation were shown from SEM analysis.

“…Saccharification is first done to hydrolyze cellulose into glucose through cellulase enzyme, followed by fermentation, where glucose is converted into ethanol through yeast [3]. Simultaneous Saccharification and Fermentation (SSF) is a method to produce bioethanol from lignocellulosic biomass where both processes occur in a single reaction at one time [4]. Bamboo is one of the most abundant natural resources in many countries, particularly those located in Asia.…”

Pretreatment of lignocellulosic biomass plays an essential role in bioethanol production as an alternative biofuel. This process reduces biomass recalcitrance in order to improve cellulose digestibility for saccharification and further fermentation reactions. In this study, microwave (MW) pretreatment was done on bamboo (Gigantochloa apus) to investigate the resulting physicochemical properties and bioethanol produced. Bamboo was irradiated in the microwave at different power (100-600 Watt) and irradiation time (5-20 minutes) followed by Water Soluble content (WSC) and lignin analysis. Simultaneous saccharification and fermentation (SSF) using cellulase enzyme was also done in five different treatment combinations (C1-C5) to investigate the effect of produced reducing sugar and bioethanol. The result shows that increasing MW power and irradiation time could decrease WSC gradually. The lowest WSC of 0.3% was obtained at 600-Watt MW power and 20 minutes irradiation time. Lignin content decreased from 18.9% to 16.0% concerning increasing irradiation time from 5 to 20 minutes under 300-Watt MW power. SEM images show that partial disruption and micro-scale pores existed in pretreated samples. The highest amount of ethanol was obtained at 24 hours fermentation for pretreated bamboo at 300-Watt MW power for 15 minutes followed by cellulase enzyme addition. The overall results showed that microwave pretreatment is a prospective method for future bioethanol production from bamboo due to effective WSC reduction and lignin degradation in a relatively short period of time.
