This research explores utilizing abundant and economical cassava as a raw material for producing cationic starch in Indonesia. Cationic starch was synthesized by etherifying cassava starch with CHPTAC monomer at 50–90 °C. Successful cationic modification was confirmed via FTIR and NMR spectra. Characterization revealed the 80 °C product exhibited optimal properties: high degree of substitution (0.35) and reaction efficiency (98 ± 1.2 %). The amorphous form of the 80 °C product reduced its thermal resistance. This economically viable process uses readily available cassava to produce high-value cationic starch, currently an expensive imported product, demonstrating potential to enhance domestic production and reduce import reliance.
