High Cellulose

Rice straw is a waste from rice plants that contains 37.71% cellulose, 21.99% hemicellulose, and 16.62% lignin. High cellulose content in rice straw can be used as raw material for the manufacture of Carboxymethyl Cellulose (CMC). CMC is a cellulose derivative widely used in food, pharmaceutical, detergent, textile and cosmetic products industries as a thickener, stabilizer of emulsions, or suspensions and bonding. This study aims to process rice straw waste into CMC with variations in sodium monochloroacetate of 5,6,7,8 and 9 grams. The method used in this research is by synthesis using 15% NaOH solvent, with a reaction time of 3.5 hours and 5 grams of rice straw. The results showed that the best CMC was obtained at a concentration of 9 grams of sodium monochloroacete with a yield characterization of 94%, pH 6, water content of 13.39%, degree of substitution (Ds) of 0.80, and viscosity of 1.265 cP.

Rice straw is one of material containing cellulose to produce Carboxymethyl Cellulose (CMC). CMC is a non toxic polysaccharide that produces from cellulose that widely used in the pharmaceutical, food, textile, detergent, and cosmetic products industries. There are two stages usually use to produce CMC which are mercerization and esterification processes. Rice straw waste is one of the materials to produce CMC, it has a cellulose content of 37.7%, hemi-cellulose 21.99%, and lignin 16.62 %.  BPS Aceh shown that the total rice harvested area was 310.01 hectares, with a total production of 1.71 million tons, and rice produced at 982.57 thousand ton. This study aims to reduce waste and environmental pollution caused by rice straw and collects information of rice straw as a basic material to produce of carboxymethyl cellulose and to increase the economic value of rice straw.  The effects of various wieght parameters sodium monochloroacetate on chemical properties of CMC that produce from rice straw were investigated in this research. Rice straw was collected from a rice field in Nisam, North Aceh. The research conducted by synthesizing 5 grams rice straw for 5.5 hours using NaOH and Sodium Monochloroacetate solutions. With variations weight of sodium monochloroacetate are 5,6,7,8 and 9 grams. The characterization of CMC was carried out by Fourier Transform Infrared (FTIR), CMC yield, DS, Viscosity, water content, pH. The result shows that addition of sodium monochloroacetate was significant factors influence the chemical properties on CMC. The CMC that produced in this study achieved to National Indonesia Standard (SNI).

Midrib is one of the palm plantation  waste that has not been utilized optimally. The high cellulose content of palm midrib is potentially converted to carboxymethyl cellulose. This study aims to determine the characteristics of carboxymethyl cellulose that produced from various concentrations of trichloroacetic acid and reaction times. This study used a complete randomized design (RAL) with two factors i.e tricloroacetic acid concentration (10%, 20% and 30%) and reaction time (3 hours and 4 hours). The synthesis of carboxymethyl cellulose in this study consists of three stages i.e alkalization, carboxymethylation and purification. The carboxymethyl cellulose obtained was characterized include degree of subsitution (DS), pH, viscosity, water content, and purity. The results showed that the best carboxymethyl cellulose was obtained from the use of 20% tricloroacetic acid and 3 hours reaction time. The characterrization result include substitution degree value of 0.76, pH of 8.32, water content of 7.1%, with a  viscosity of 7.8 cP,   and purity of 92.62%.

<em>Corn stalk has a high cellulose content, so that it is potential to be used as a composition for making alginate-carboxymethyl cellulose beads. Alginate and cellulose are biodegradable, renewable and non-meltable polymers that have wide applications in various industrial sectors. The purpose of this study was to determine the effect of crosslinking agent C<sub>4</sub>H<sub>6</sub>O<sub>4</sub>Zn on the adsorption and shape of beads. The varied concentrations of C<sub>4</sub>H<sub>6</sub>O<sub>4</sub>Zn are 3%; 5% and 10%. Characterization of alginate-carboxymethyl cellulose beads composites using Fourier Transform InfraRed (FTIR), and Scanning Electron Microscope-Energy Dispersive X-Ray (SEM-EDX).</em> <em>Based on research, the highest swelling value is obtained at 5% C<sub>4</sub>H<sub>6</sub>O<sub>4</sub>Zn crosslink which is 59.68%. FTIR data shows the appearance of wave numbers at 1413 cm<sup>-1</sup> which indicates the presence of C-O Na groups, while at wave number 458 cm<sup>-1</sup> indicates the presence of Zn-O groups. SEM-EDX data with a 5% C<sub>4</sub>H<sub>6</sub>O<sub>4</sub>Zn crosslink has a round shape with a wrinkled surface, multiple grooves causing a non-homogeneous surface. Whereas in C<sub>4</sub>H<sub>6</sub>O<sub>4</sub>Zn 10% the surface is almost smooth</em>
