Good forest management activity needs an accurate and precise management plan in order to ensure forest sustainability, both for yield (timber productivity) and forest ecology. To identity the quantity forest product needs tree volume estimation instrument. This study was there for conducted for building volume equations and thinning volume table for teakwood on BH Banglean, KPH Randublatung Perum Perhutani Unit I Central Java. This research has two equations which were equations with an independent variable (dbh) using Berkhout V=α(D) b model and estimated volume equation with two independent variable (dbh-h) using Schumacher Hall V=α(D) b (h) c model. Equation modeling was performed using the data of 190 trees and 95 trees to validate the equation model. Result one stimated volume equation would be examined for its model acceptance equation using following criteria: coefficient of determination (R 2 ), adjusted R square (Radj 2 ), t test and F test signification. Validation test was test in accordance with criteria of aggregate deviation (SA) and mean deviation (SR). Validated equation was used to compose the volume table. Berkhout model equation compilation was V=3.4x10 -5 (Dbh) 2.782 with coefficient of determination with value (R 2 ) of 0.986 and Radj 2 =0.971 with value of SA=1% and SR=9.07%. Schumacher hall model of estimated volume equation was V=7.53x10 -5 (dbh) 2.256 (h) 0.364 with coefficient of determination value of (R 2 )=0.989 and Radj 2 =0.978 with value of SA=0.6% and SR=1.08%. Based on through both equations it could be concluded that equation with one variable was more practical, biside adding high variable had a small contribution in estimated volume equation.
