Optimization of Ammonia (NH3) and Rice Husk Liquid Smoke Against Latex Precoagulation and Coagulation Time

Latex Precoagulation and Coagulation

Abstract

This study aims to determine the effect of variations in the concentration of ammonia as an anticoagulant agent and rice husk liquid smoke which is optimal as a coagulant agent in latex. This research consists of 2 observations. The first observation was made by adding variations in the concentration of ammonia to the liquid latex sample and observing the precoagulation time. In the first observation sample, ammonia was added at a concentration of 2%, 2.5%, and 3% respectively and then observed. The two latex observation samples that had been added with ammonia with an ammonia concentration of 2%, 2.5% and 3% were then added with liquid smoke with a volume of 2 mL, 4 mL, and 6 mL. The first observation results obtained showed that the concentration of ammonia used as an anti-coagulant agent 2% was able to prevent coagulation for 10.1 hours, 2.5% ammonia concentration for 12.0 hours, and 3% concentration for 13.0 hours. Whereas in the second observation to determine the optimal value of the ammonia concentration and liquid smoke volume used to get the optimal ammonia concentration and liquid smoke volume. The results obtained based on the results of the Response Surface Methode analysis, the optimum ammonia concentration that is good to use is 2% and a volume of 4.87 mL of liquid smoke with a coagulant retention time of 2.07 hours. The results of the second observation validation showed that the ammonia concentration and volume of liquid smoke suggested by the software resulted in a coagulant retention time of 2.05 hours.
