The preservation of green goat skin using liquid smoke from coconut shell

The objective of the research on the presentation of green goat skin using liquid smoke was to reduce the environmental contamination caused by usage of the environmentally-unfriendly chemical in skin preservation process. Liquid smoke is the outcome of coconut shell waste containing a lot of phenol and acid compound. It is an organic material that is environment-friendly and it can inhibit the bacteria growth. The research was conducted using 18 pieces of green goat skin. Eighteen pieces of green goat skin were divided into 2 treatments. The first stage treatment used liquid smoke as the preserving material with 0,1%, 0,5%, and 1,0 % in concentrations without crystal salt and anti-bacterial material. The second stage treatment used liquid smoke with 5%, 10% and 15% in concentrations and used crystal salt without anti-bacteria material. The skins then were stretched and dried in the sun. They were observed for 1 week, 2 weeks and 1 month. The results of the skin preservation then were tested in organoleptic method, including the tests for the shedding of feather and the damage of skin owing to bacteria / louse. The skins also were tested in physical method (tensile strength & elongation at break). The result of search showed that the skins preservation for month using liquid smoke, 10% in concentration, was the most effective, Usage of liquid smoke as the substitute of anti-bacteria/fungicide would reduce a part of the environmental contamination owing to usage of the environment-unfriendly chemical in skin preservation process.
