Sintesis nanoselulosa dari limbah hasil pertanian dengan menggunakan variasi konsentrasi asam

Agricultural waste is a huge source of fiber. There are many agricultural waste products in Lampung Province including rice straw and corn. The utilization of agricultural waste is one solution to get cellulose-producing materials. Nanocellulose is one of the uses of cellulose which is very beneficial for life. Nanocellulose can be divided into 3 main types namely nano crystal cellulose, nanofibril cellulose, and bacterial nanocellulose. Nanocellulose has a diameter of 1-100 nm and a length of 500-2000 nm. Several techniques were developed to extract nanocellulose from cellulose including acid hydrolysis, enzymatic hydrolysis, and mechanical processes. The use of each extraction method is possible to produce different types and properties of nanocellulose. This research aims to synthesize nanocellulose from agricultural waste with various concentrations of acid to produce cellulose with the best nano size ranging from 1- 100 nm. H2SO4 concentration variations used are 45%, 55%, and 65%. From this study produced cellulose powders with varying nano sizes. The size of nanocellulose produced ranged from 356.5 nm - 764.2 nm for rice straw, and 422.6 nm - 634.0 nm for corn husk.
