  • ABSTRACT Sonokembang (Pterocarpus indicus Wild) is a multipurpose plant that can be developed with vegetative and generative multiplication in the development of growth regulator that is ZPT Rootone F and various planting media in the specified. In order to know the long-wining of the immersion ZPT Rooton F, the influence of media and interaction between the planting media and the prolonged influence of immersion. The method used in this research is a random design of a group (RAK) compiled in factorial, consisting of two factors namely the first factor is the composition of the planting Media (A), while the second factor is the length of immersion (F) with the formula (n × T-1 ≤ 15). N is a replay and T is a treatment. The conclusion of this study is 1. Long immersion with ZPT such as ZPT Rooton F with the long soaking a different effect very real long this perendama it is best 15 minutes. 2. For the media itself very influential real. Media cocopeat is one of the best media in the study. 3. The interaction of the media and the long immersion of the study was significantly influential, such as soil and cocopeat with a long immersion of 15 minutes (A3F3) showed good results and very noticeable effect on each observation parameter.
