Aur bamboo (Bambusa vulgaris) is a plant that is widely used by the people of West Java. This bamboo grows a lot on community plantations, mainly used for fences and cliff-reinforcing plants. In addition to providing ecological benefits, Aur bamboo has a lot of potential, including as a raw material to replace granite (battery raw material) and has the best quality activated charcoal from other bamboos. The success rate of producing aur bamboo seedlings through the propagation of branch cuttings is still very low. The solution to increase seedling production is through the propagation of cuttings using growth-stimulating substances. From research that has been done that liquid smoke has the potential to be a stimulant for the plant growth. This study aims to determine the effect of dosage and duration of immersion in liquid smoke on the growth of aur bamboo cuttings. This research was conducted in April-June 2021 at the Gunung Geulis Forum nursery, Jatiroke Village, Sumedang Regency. The study used a completely randomized design with 2 treatments, namely the dose of liquid smoke consisting in ppm of 5000 (P1), 4000 (P2) and 5000 (P3) and the immersion time consisted in minute of 15 (M1), 30 (M2) and 45 (M3). The parameters measured consisted of the number of shoots, shoot length, number of roots and root length. The results of data analysis showed that the administration of liquid smoke at a dose of 3000ppm-5000ppm with a soaking time of 15-45 mnt did not significantly affect the growth of aur bamboo branch cuttings aged 2 months after planting. However, the results it is known that immersion of bamboo aur cuttings material for 30 mnt in a solution of 3000 ppm liquid smoke, resulted in an increase in the number of shoots, shoot length, root number and root length which was higher than the other treatments, namely 1 ,6; 1.03 cm; 1.4; 4.12 cm.
