Penelitian ini bertujuan untuk mendapatkan 5-hidroksimetilfurfural melalui reaksi konversi selulosa ampas sagu dan mengetahui karakterisasi produk 5-hidroksimetilfurfural hasil dari konversi selulosa ampas sagu. Untuk mendapatkan selulosa dilakukan beberapa tahapan: tahap dewaxing, tahap dehemiselulosa, tahap delegnifikasi, tahap bleaching, dan selulosa dikarakterisasi menggunakan scanning electron microscope (SEM). Hasil konversi selulosa menjadi 5- hidroksimetilfurfural dikarakterisasi menggunakan High Performance Liquid Chromatograph (HPLC), dan Fourier Transform Infrared spectroscopy (FTIR). Hasil penelitian menunjukkan bahwa terdeteksi adanya konsentrasi 5-HMF sebesar 11,203 mg/mL dengan waktu retensi sebesar 24,477 menit, dan pada area 154274.

ABSTRACT
Novita Dahlan, 2022. â�Å"Cellulose Conversion Reaction From Sago Dregs Biomass To 5 â�" Hydroxymethylfurfural�Thesis for Undergraduate-Chemistry Program, Faculty of Mathematics and Natural Sciences, State University of Gorontalo (UNG). Advisor I Prof. Dr.Ishak Isa, M.Si, and Advisor II Wiwin R. Kunusa, S.Pd, M.Si.
This study aims to obtain 5-hydroxymethylfurfural through the conversion reaction of sago pulp cellulose and to determine the characterization of the 5-hydroxymethylfurfural product resulting from the conversion of sago pulp cellulose. To obtain cellulose, several stages were carried out: dewaxing stage, dehemicellulose stage, delegnification stage, bleaching stage, and the cellulose was characterized using a scanning electron microscope (SEM). The results of the conversion of cellulose to 5-hydroxymethylfurfural were characterized using High Performance Liquid Chromatograph (HPLC), and Fourier Transform Infrared spectroscopy (FTIR). The results showed that the 5-HMF concentration was detected at 11.203 mg/mL with a retention time of 24,477 minutes, and in the area of 154274.
Keywords : Sago Dregs, Cellulose, 5-Hydroxymethylfurfural
