Abstract
Sengon (Paraserianthes falctaria (L.) Nielsen) merupakan jenis tanaman kayu yang banyak digunakan dalam berbagai industri di Indonesia. Dalam industri pengolahan kayu sengon dihasilkan limbah berupa serbuk maupun potongan kayu. Limbah sengon ini berpotensi untuk diolah kembali menjadi produk yang bernilai jual tinggi seperti Microcrystalline Cellulose (MCC) karena memiliki kandungan selulosa cukup tinggi yaitu sebesar 45,42%. Produksi Microcrystalline Cellulose (MCC) dilakukan dengan tiga proses utama yaitu delignifikasi, hidrolisis, dan bleaching. Dalam rangka mendukung program sustainability development goals (SDGs) maka perlu adanya modifikasi proses yang lebih ramah lingkungan. Pada penelitian ini dilakukan proses biodelignifikasi menggunakan white rot fungi jenis Trametes versiocolor dengan pre-treatment sonikasi supaya lignin dapat mengalami degradasi. Proses hidrotermal merupakan salah satu metode yang memanfaatkan kondisi subkritis air sehingga dapat digunakan sebagai alternatif untuk meningkatkan kristalinitas produk dan degradasi hemiselulosa. Proses bleaching menggunakan bleaching agent bertujuan untuk mengambil lignin yang tersisa serta mengikat monomer lignin yang dihasilkan dari proses delignifikasi. Pada penelitian ini, bleaching agent ditambahkan pada proses hidrotermal sehingga didapatkan produk MCC dengan penggunaan bahan kimia konsentrasi rendah. Hasil yang didapatkan dari penelitian ini berupa komposisi lignin, selulosa, dan hemiselulosa, kristalinitas, hasil SEM, Pyrolisis GC-MS, dan FTIR

Sengon (Paraserianthes falctaria (L.) Nielsen) is a plant that widely used in various industries in Indonesia. In the sengon wood processing industry, waste is produced in the form of sawdust or pieces. Sengon waste has great potential to be processing into products with high selling value such as Microcrystalline Cellulose (MCC), since it has a fairly high cellulose content of 45.42%. Production of Microcrystalline Cellulose (MCC) is carried out by three main processes, namely delignification, hydrolysis, and bleaching. In order to support the sustainability development goals (SDGs) program, it is necessary to modify processes that are more environmentally friendly. In this study, the biodelignification process was carried out using white rot fungi Trametes versiocolor pre-treated with sonication, so that lignin could be degraded. The hydrothermal process method utilizes the subcritical conditions of water so it can be used as an alternative to increase crystallinity of product and could degrade hemicellulose content. The bleaching process using a bleaching agent aims to degrade the remaining lignin or even the lignin monomers produced from the delignification process. In this study, a bleaching agent was added to the hydrothermal process to obtain MCC products using low concentrations of chemicals. The results obtained from this study were the composition of lignin, cellulose, and hemicellulose, crystallinity of product, SEM results, Pyrolysis GC-MS results, and FTIR results
