QUALITY TEST OF CMC (CARBOXYMETHYL CELLULOSE) USING SEMI-BATCH REAKTOR

Carboxymethyl Cellulose, one of the additives commonly used in the industrial sector, is carboxymethyl cellulose. The state of the art of this research is because no research makes a reactor to manufacture carboxymethyl cellulose. This study tested the quality of making carboxymethyl cellulose using a semi-batch reactor using samples of potential organic cellulose waste materials: durian seeds, taro rods, and bagasse. This sample has been used to make carboxymethyl cellulose in previous studies using a laboratory scale. Then compared, the manufacture of carboxymethyl cellulose using a reactor laboratory scale. From the result obtained, carboxymethyl cellulose from durian seeds, taro rod, and bagasse made on a laboratory scale and using a reactor has become carboxymethyl cellulose in quality number 1 and 2, which are commonly called carboxymethyl cellulose industrial grade and food chemical codex quality which met the minimum quality requirements by SNI 8762; 2019. Carboxymethyl cellulose from durian seeds, taro rod, and bagasse obtained from research that has been tested with FTIR, the spectra of the best results of carboxymethyl cellulose from durian seeds, taro rod, and bagasse can be seen in the picture there are similar peaks that appear indicates carboxymethyl cellulose durian seeds, carboxymethyl cellulose taro rod, and carboxymethyl cellulose bagasse produced in this study have the same chemical molecule as industrial grade and food chemical codex.1.2
