Stand density arrangement plays an important role on development of plantation forest to obtain optimal result. This research presents a way of bambang stand density arrangement based on crown development. Optimal crown area (ca) is determined by regression equation between diameter of breast heigh (dbh) and crown diameter (cd). While stand density is determined by dividing plantation area with optimal crown area (ca). Data collection was carry out by measuring 380 tree sample on farm forestry in Lahat Regency, Empat Lawang Regency, and Pagar Alam City. Regression equation both variable was formulated based on 280 tree samples and validated of 100 samples remain. Result showed that correlation equation between diametre brest heigh and crown diametre with the highest accuration is quadratic equation Cd = 3.15 + 0.0391 Dbh + 0.00251 Dbh (R 68.52%, bias 0.2% dan RMSE 73.76%).
