Abstract
Punak (Tetramerista glabra Miq) is an indigenous plant species growing in peat swamp forest that can be propagated vegetatively through shoot cuttings. Punak can be used as a material for plywood,boards, poles, and firewood. The purpose of this study was to obtain root stimulants and growth media to be suitable for the growth of punak shoot cuttings. This research was conducted at the Silviculture Laboratory and screen house of the Ruang Pamer and Bursa Anggrek, UniversitasTanjungpura.This study used split plot design with a completely randomized design (CRD). The main plot factor was growth media with two levels of factor (cocopeat and cocopeat + husk charcoal) and the sub plot factor was root stimulants with three levels of factor (without root stimulants, rootone-F, and wood vinegar). The results of this study show that the percentage of life of shoot cuttings was 80 %, while the percentage of cuttings was rooted at 66.66%. Therefore, the effect of root stimulant and growth media are not significant in the growth of punak shoot cuttings, as seen from the time of planting until three-month-observation.Keywords: cocopeat, husk charcoal, peat, restoration, wood vinegar

Summary
0,58 tn Berdasarkan hasil penelitian 12 minggu di lapangan dapat dilihat pada Tabel 1 perlakuan stimulan akar dan media tumbuh yang telah diberikan tidak berpengaruh nyata terhadap pertumbuhansetek pucuk punak. Selama penelitian tiga bulan tidak semua setek yang diuji cobakan telah membentuk akar, diduga setek pucuk belum memberikan respon pertumbuhan perakaran yang maksimal berkaitan dengan jangka waktu pengamatan yang relatif pendek. Waktu pengamatan juga bisa ditambah (lebih lama) sehingga perakaran setek pucuk punak telah mencapai fase maksimal.Walaupun tidak berpengaruh nyata setek pucuk punak, yang tidak diberikan penambahan stimulan akar juga mampu tumbuh dengan baik. Hal ini menunjukan adanya perakaran dan munculnya tunas baru, karena hormon endogen dalam tanaman telah mencukupi untuk pertumbuhan akar primordial, sehingga pertumbuhan setek pucuk punak mampu bertahan hidup hingga akhir penelitian. Rerata persentase hidup setek pucuk punak selama 12 minggusetelah tanam (MST)(The average life presentation of punak shoots cutting for 12 weeks after planting)
