The research was conducted at the cutting red bettle (Piper crocatum Ruiz and Pav.) to determined the effect of (1) the difference growth of cuttings of red bettle which are given IBA and without IBA, (2) the concentration of NAA on growth of cutting red bettle, (3) the concentration of NAA on growth of cutting red bettle on each given IBA. The treatment was arranged in factorial (2 x 4) in randomized block design with three replication. The first factor were without IBA (A) and the given of 1000 ppm IBA (A1). The second factor were the concentration of NAA consists of: 0 ppm (B), 1000 ppm (B1), 2000 ppm (B2), and 4000 ppm (B). The results showed that the NAA concentration of 4000 ppm produced the most number of roots on either at the node or at the base of cutting. Planting cutting red bettle which given IBA 1000 ppm was able to accelerated the time leaves open and increased the number of cutting which germinate. The mixtured of giving IBA 1000 ppm and the concentration of NAA 4000 ppm, produced the most number of cutting that germinated.
