"PENENTUAN LIMIT DIAMETER TEBANG PILIH BERDASARKAN KRITERIA TINGGI ANAKAN DAN FAKTOR EKONOMIS"
Abstract
Indonesia Selective Cutting System (TPI, nowTPTI) is the most widely applied management regime in harvesting Indonesian tropical forests. It is observed that selective cutting has created space and canopy openings in the forest which stimulate the growth of seedlings and saplings of meranti species (Shorea spp). A study was conducted to examine the relationship between the seedlings height with basal area of trees in several sample plots in logged-over forests. The relationship expressed in regression equation then was used to relate the seedlings height to the cutting diameter limit.
As determination of cutting diameter limit leads to important decision in the selective cutting, a problem of findine the optimal diameter limit which maximizes the seedlings height constrained with economic factor is formulated by using nonlinear programming.
