Durian wood is a type of wood that grows in abundance the region of Gunungpati Semarang, Indonesia. Unfortunately Durian timber is included in the type of wood that is not resistant to termite attack, so they need to be preserved in order to increase the durability. One of the plants that can produce natural preservatives is the Kecubung fruits (Datura Metellinn) containing very strong toxins (alkaloids). This research used experimental method, by cold soaking method preservation with concentration of preservative extract of Kecubung fruits 0%, 15%, 20%, and 25%, duration time 120 hours. The result of the experimental research showed that the termite endurance test on durian timber at 0% concentration of preservative (control test specimens) the weight had decreased by 17.89%, while the concentration of preservation at 15%, 20%, and 25% had deceased the weight by 10.49%, 8.78%, and 3.63% respectively. Therefore, preservation of durian timber using cold soaking method at 120 hours by using the Kecubung fruits extract with 25% concentration gives the best result and the Kecubung fruits can be the alternative solution for the wood preservation which is the form of organic compound and environmental friendly.
