Abstract
The objective of this project is to develop a cold and hot medical gel from carboxymethyl cellulose
from durian rind. By studying the preparation of Hydrogel 3 properties as following. Hydrogel ACG,
Carboxymethyl cellulose, Alginate and Guagum as a substrate-binding with double-mechanical via
sodium tetraborate and calcium chloride. Studying the differentiation of substrate ration when the
binding substance is equal to 0.5 and 1.0 percent by volume. The production hydrogel will be tested in
absorption state by testing absorption in different acidity of water and different of temperature. Test the
change in temperature of gel and test the ability to maintain the temperature in the gel. Found out that,
a hydrogel with A1C3G6-10 formula has the highest ability to maintain the temperature. Therefore, the
A1C3G6-10 formula is the most appropriate formula for medical use. Because of the soft texture, high
flexibility, high capacity of absorption, and fast change in temperature.
