The use of Starch from Taro tubers as an adhesive raw material is done by hydrolyzing talc of Taro Tuber into dextrin using Chloride Acid (HCl) as the catalyst. The variables involved in this research are temperature and hydrolysis time whence the variations of temperature are 80⁰C, 100⁰C, 120⁰C, and 140⁰C also for the duration of hydrolysis time are 10, 20 and 30 minutes. The variations of temperature and time can affect the nature of dextrin produced. The analysis parameters include swelling power, solubility, dextrose equivalent (DE) and water content. The hydrolysis of taro tuber starch is then added with sodium bicarbonate (NaHCO3) and formaldehyde solution (CH2O). The mixture is added with some water and heated to a temperature of 60⁰C to form a homogeneous mixture. After the Dextrin Glue is formed, the process is continued by analyzing the adhesive power of the synthesized gluten. From the research’s outcome, knowing that the optimum condition of adhesive was at 80⁰C and 30 min of hydrolysis time also the analysis number of swelling power is 2.27, along with 1.7% solubility, dextrose equivalent 3,523%, moisture content 14% and the adhesion 283,84 N/cm2.
