Application of Silviculture Techniques to Improve Productivity of Binuang Bini Plant (Octomeles Sumatrana Miq.) as an Alternative Plant in Community Forest

Abstract

Currently the type of wood in community forests on Java Island is dominated by sengon species. However, this type faces problems with attacks of gall rust diseases One of the potential species as a substitute for light construction wood is binuang bini (Octomeles sumatrana Miq.). To increase stand productivity, it is necessary to apply the right silvicultural techniques. The purpose of this study was to find out the right silvicultural technique in order to increase the productivity of the binuang bini stands. The study design used a split plot design. The results showed that the organic fertilizer dose had a significant effect on the growth of the diameter and height of binuang bini stands. Fertilizing used bioactive compost charcoal with a dosage of 4 kg / planting hole can increase the growth in height and diameter of binuang bini plants was twice that of control treatment at the age of 30 months after planting. The pattern of binuang bini planting can be mixed with the other species such as Mindi (Melia azedarach L.) and/or Trema (Trema orientalis L.)
