| dc.description.abstract | Forest inventory is activities to know and obtain data along information about resources, potential values, and full of environments . The main objective of forest inventory activities is getting data about the condition of timber standing stock. To help forest inventory activities is needed supporting tools to facilitated this measurement and as well as to reduce human error that include tree’s volume table. PT. Mamberamo Alasmandiri have a heterogeneous diversity of tree’s species, one of them is nyatoh (Palaquium spp.). The main objective of this research is to establish local volume table nyatoh (Palaquium spp.). The volume table model using 150 trees that have been felled, selected by purpossive sampling. The regression equation that used including Berkhout equation, Kopezky- Gehrhardt, and Horenald-Krenn. Some of test that used for selecting the best model are analysis of variance, residual analysis, and outlier analysis. Validation model using Jacknife Procedures base on predicted residual sum of square (PRESS) value. The criteria used for selecting the best model is coefficient of determination (R²), adjusted coefficient of determination (Ra²), standard deviation (s), aggregate deviation (SA), average deviation (SR) and RMSE. The best model of nyatoh (Palaquium spp.) in IUPHHK-HA PT. Mamberamo Alasmandiri is V = 0,000158 Dbh2,48. | en |
