“…Sugarcane bagasse (SCB), a lignocellulosic residue from the sugar industry, is one of the most abundant agro-industrial biomass [3]. However, research activities in the field of SCB were mainly focused on converting it into fuel or using as raw materials in papermaking industry [4,5]. Recently, there are increasing interests towards high value utilization of SCB and various processes have been set up with SCB as raw material [6,7,8].…”

Esterification is a versatile way to produce the derivatives of lignocellulose with developed properties. However, the traditional heterogeneous esterification of lignocellulose suffered from the drawbacks of low efficiency, additional reaction medium and heating. In the present study, an efficient method was developed to produce the functionalized sugarcane bagasse (SCB) by ball milling without any additional solvents and heating. The effects of pulverization time, rotation speed, the kind of linear chain anhydrides, the ratio of anhydrides to SCB, with or without pyridine catalyst and the dosage of catalyst were investigated on weight percent gain (WPG) of SCB esters. The results indicated that the high efficiency of this mechanocatalystic esterification was probably due to the destroyed crystalline structure and the promoted penetration of the esterifying reagent onto SCB bulk caused by ball milling. The maximum WPG of SCB acetate, propionate and butyrate reached 33.3%, 33.6% and 32.4%, respectively. The physicochemical structure of the esterified SCB was characterized with Fourier transform infrared spectra (FT-IR), solid state cross-polarized magic angle spinning 13C nuclear magnetic resonance (CP/MAS 13C-NMR), X-ray diffraction (XRD), scanning electron microscopy (SEM) and thermogravimetric analysis (TGA). The direct evidence of the esterification occurrence was provided with FT-IR and solid-state CP/MAS 13C-NMR. The thermal stability of SCB increased upon the mechanocatalytic esterification. The results implied that the relatively homogeneous modification was achieved with this semi-homogeneous esterification method by ball milling.

“…The linear tensile strength value increases along with the increasing concentration of chitosan. Chitosan can interact with cellulose [11]. The interaction formed is in the form of a hydrogen bond between the (-OH) group on cellulose with the (-NH2) and (-OH) groups on chitosan.…”

“…The interaction formed is in the form of a hydrogen bond between the (-OH) group on cellulose with the (-NH2) and (-OH) groups on chitosan. The more chitosan is added, the more hydrogen bonds are formed therefore the tensile strength increases [11,12].The tissue paper with the lowest concentration of chitosan has a tensile strength value that is close to commercial facial tissue (T6). The tissue soaked in the chitosan solution caused some of the chitosan to occupy the pores and part of it only sticks to the surface of the tissue.…”

The demand of tissue papers is increasing with the population increase. This will definitely increase the need of wood fibers as the main raw material. However, due to the wood shortages, there have been many attempts to use nonwood fibers as substitutes for papermaking. In Indonesia, corn production has gradually increased for the last 5 years, hence it also has an impact on the raising in the amount of corn husk waste. Corn husk has a high cellulose content which suitable to be used as a raw material for tissue papermaking. In this experiment, soda pulping process was conducted to remove out lignin. The resulting tissue paper will be added with additives that have antimicrobial properties of chitosan and mangosteen peel for the purpose of increasing the tensile strength or absorption of water. The aim of this research is to study the effect of depending variables (temperature and NaOH concentration) on chemical composition (cellulose and lignin content), and physical properties including water absorption and tensile strength.The research was started with the initial process of removing the lignin content in the pulp by pretreating delignification using the sodium hydroxide (NaOH) process with several variations in concentration (4-10%), and temperature (60-90°C) for 1.5 hours. To obtain tissue with a good physical condition, it has been influenced by the optimum chemical composition containing high cellulose and low lignin content, high tensile strength and water absorption. The optimum conditions for tissue paper in this study were at 90°C and 4% of NaOH concentration. The next step will be to vary the composition of the additive in order to obtain the effect of physical properties (tensile strength and water absorption).

“…Penggunaan suhu yang tinggi mampu mempercepat reaksi bahan kimia pada biomassa, melalui pengrusakan ikatan pada rantai lignin dan hemiselulosa, sehingga proses degradasi berjalan dengan baik, dan menghasilkan selulosa dan yield yang tinggi. Salah satu fakta menarik adalah suhu dan waktu berperan dalam proses delignifikasi, peningkatan suhu akan meningkatkan proses delignifikasi dan mempersingkat waktu proses, Suhu tinggi mempercepat proses solubilisasi rantai polisakarida (Suseno, Sapei, Purwanto, & Adiarto, 2017). Hal ini sejalan dengan hasil penelitian Mukherjee et al (2018) yang menunjukkan bahwa pada suhu yang lebih tinggi, tingkat energi aktivasi menurun, mempersingkat waktu proses dan akan meningkatkan jumlah pengurangan lignin dari jerami padi.…”

This study aims to optimize the temperature and time of the delignification process to isolate cellulose from corn cobs. The research was carried out in stages, namely preparing corn cob powder samples and the delignification process. Statistical regression modeling and optimization of the temperature and time of the delignification process used the response surface (RSM) methodology. Central Composite Design (CCD) was used for experimental design and analysis of the effect of temperature and time of the delignification process on lignin, cellulose, hemicellulose, and fiber yields. The optimum process conditions were determined using the desirability method. The analysis of the diversity of the quadratic polynomial model shows that the temperature and time of the deligninification process significantly affect changes in the characteristics of lignin, cellulose, hemicellulose, and fiber yields. The optimal condition of the corncob fiber delignification process was obtained at a temperature of 100.38? for 79.17 minutes. It produced the characteristics of delignified fiber with lignin, cellulose, hemicellulose, and yields of 6.47%, 73.73%, 5, respectively. 39% and 57.76% w/w. The optimization model is valid with a desirability value of 0.71. Thus, the temperature and time optimization model of the delignification process can be applied in real conditions to produce delignified corncob fiber with optimum characteristics.
