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.
