Abstract

Sengon is a plantation forest industry that produces lumber and benefits the welfare of society. Sengon, including seeds by the balls hard, then need breaking dormancy the research was carried out by using the random factorial of two factors. The first factor consists of 4 levels and the second consists of four standards, that are repeated three times. The first factor is put in plain water with a temperature between 27-28oC for 24 hours (P0), seed in the oven with a temperature of 400 C for 24 hours (P1), and seed soaked in hot water (the temperature of 80oC) for five minutes (P2), seed soaked in brine H2SO4 80% for 15 minutes (P3). The second factor iwas the media tree twhich is the top soil+sand (K0), top soil+sand+manure goat (K1), top soil+sand+manure chicken (K2), and top soil+sand+compost (K3). Security board of directors consisting of plants, it drenched the plant, I know dry, plants, the roots, the Diameter of the Bar. The result observations on each side variable are analyzed by using ANOVA to proceed with trials with a continued DMRT of 5%. The results showed that treatment featured dormancy P2 influence a significant on the parameters of the plant height and long roots, you know the first quarter gave significance on the parameters of heavy wet plant, but the different reality on the parameters of the plant height and weight of dry plants. There are the interactions of the P1K1 of influence to the heavy wet. Key words; Dormancy, Sengon, Planting Media
