Abstract
With the increasing world demand for pine resin, one of the efforts that can be made to increase the production of pine resin is to use stimulants of sap / stimulants. So far, in the activity of tapping pine sap, inorganic stimulants are used, but the main components are sulfuric acid and nitric acid or a mixture of which is a strong oxidizing agent that can damage human skin, wood and the environment if used in the long term and excessively. Alternative use of stimulants from natural ingredients that are safe, relatively inexpensive, and easy to obtain, such as galangal (Alpinia galanga) and ginger (Zingiber officinale). This research was conducted to determine the effect of stimulant administration of galangal and ginger extracts on increasing the productivity of pine sap. The results of this study showed that the highest sap productivity was produced by pine trees using ginger organic stimulants with a 50% concentration of 11.15 g / koakan / day. The quality of pine sap that has the best quality is produced by the stimulant of ginger, while the use of the stimulant of galangal has second quality based on SNI 7837: 2016.
