Kranji (Pongamia pinnata Merril) is one type of forest plants that have the potential as a source of renewable energy in the future. Kranji seed produces vegetable biofuel material, so we need another way to get the seedlings, one of them by cuttings. Moreover, the traits of the parent will be derived through vegetative propagation. This study aimed to determine the effect of plant material to the success of cuttings kranji. The plant treatment factors included the types of buds, shoots age, the part of buds and leaf on buds. The experiment based on the type of shoots used a randomized block design consisted of two treatments, dormant buds and growing shoots, with 5 replications, each treatment combination consisted of 50 cuttings. The experiment based on the age of shoot used a randomized block design consisted of 5 treatments (ages of 2, 3, 4, 5, and 6 months) with 5 replications, each treatment combination consisted of 50 cuttings. The experiment based on the part of shoot used a randomized block design consisted of three treatments (base, middle, and end of shoots) with 5 replications, each treatment combination consisted of 50 cuttings. Meanwhile, the treatment based on the leaf on buds used a randomized block design consisted of two treatments (with leaf and without leaf) with 5 replications, each treatment combination consisted of 50 cuttings. The results showed that the treatment of the types of buds and the leaf on buds were not significant to affect on all parameters observed. The age of shoots gave a significant effect to a percentage of growing cuttings, but did not a significant effect on other parameters. The part of shoots gave a significant effect on all parameters observed. For the procurement of kranji seedling by cuttings should use the age of shoots 2, 3, or 4 months and the middle part of the shoot.
