Abstract

Cassava stems contain 56.82% α-cellulose, 21.72% lignin, 21.45% Acid Detergent Fiber (ADF), and a fiber length of 0.05-0.5 cm. One cellulose derivative product that is frequently utilized in the food and pharmaceutical industries is hydroxypropyl methylcellulose (HPMC). This study aims to produce HPMC from α-cellulose derived from cassava stems HPMC Batang Ubi Kayu (HPMC BUK) according to HPMC standard specifications (HPMC Komersil (HPMC KO)). In this study, extraction of α-cellulose from cassava stems was carried out using electromagnetic, pre-hydrolysis, delignification, and bleaching processes, then α-cellulose was treated with alkalization by adding 20 ml of NaOH with variations concentration 20% w/v, 25% w/v, and 30% w/v at room temperature with time variations of 60 minutes, 120 minutes, and 180 minutes. Then followed by a methylation reaction using 6.3 ml of dimethyl sulfate (DMS) and a propylation reaction using 6 ml of propylene oxide (PO) (for 5 g of α-cellulose) at a temperature of 58.11℃ for 3 hours and continued with neutralization, filtering, and drying. The optimum conditions were obtained using 25% (w/v) NaOH with a reaction time of 60 minutes which resulted in HPMC specifications being yellowish-white, odorless, and tasteless, pH 7.7 and ash content 1.3%, water content 7.44%. The average particle size of HPMC BUK was 49.57 µm, with crystallinity of 12.5% with an oval shape and rough surface. The FTIR spectrum shows a relatively similar pattern to that of commercial HPMC. Based on the comparison with the reference, HPMC BUK showed relatively the same physicochemical characteristics.
