Abstract
of the experiments preparing a science project. The study compared the glue made from local plants
with the aim of the study were 1) to study how to produce adhesives from cassava simple 2) to compare the glue is made from tapioca flour with rice flour and glutinous rice flour type available. effective 3) to compare the two with adhesive glue made from commercially available. The methods and procedures Part 1: 1) scale cassava. Rice flour And flour a dry powder in a beaker at least 10 grams 2) distilled water into the beaker three 30 ml and stir the flour mixture with water 3) Remove the beaker three set. stir over low heat for about 10 minutes, then raised to 4) observed physical characteristics. And recorded the second one), choose the paper type 70 80,150,180 2 and 200 gsm) of paper cut to size each other up. 7x21 cm 3) Fold into a triangle, the size of paper to the same glue the two sides opposite each drill hole 4) Remove the paper from the third to test the viscosity of the adhesive, the three kinds of time to comment. 5 minutes, then using a balance springs observe and record the 3 1) Remove the glue that holds the most cohesive of the two compared to the adhesive market by sticking to the paper 70 80,150,180 and 200 grams of prepared second. ) toughness test The duration of the next five minutes, then using a balance springs 3) observe and record the results of the experiment showed that: when the first batter of each type will be changed to increase the amount of water. As the physical characteristics of the glue on the table when the two results from the three types of glue which keeps us know. Cassava starch glue Each paper will stick firmly to get better. Is based on the assumption that the first try was the glue made from rice flour made from tapioca starch glue Episode 3 Attach a sticky better. Glue the market It is based on two assumptions.
