Pengaruh Suhu Dan Waktu Proses Karboksimetilasi Terhadap Karakteristik Carboxymethyl Cellulose (CMC) dari Onggok Singkong


 Onggok is an organic waste from tapioca production rich in cellulose but has not been utilized fully for other usages. This study aimed to determine the appropriate temperature and time carboxylation process produce CMC cassava with best characteristics. used a factorial randomized block design. Factor 1 was (40oC, 55oC, 70oC) factor 2 (2 hours, 3.5 5 hours). The observed variable yield, water content, substitution degree, viscosity, purity. results showed that interaction affected degree of substitution, NaCl purity CMC. treatment obtained combination 40oC processed hours yield value, moisture 83.97±1.36%, 9.58±0.67%, 0,89±0.06, 105.00±21.21cPs, 97.55±0.66%, respectively
