Judul: Penyusunan Tabel Volume Jenis Rhizopora apiculata di Areal IUPHHK-HA PT. Bina Ovivipari Semesta Kalimantan Barat.
Abstrak: In every forest management system, forest inventory hold important role in providing various information either regarding forest area, forest stand or forest product. Within the forest inventory activities, development of supporting tools, such as tree volume table, tree height curve and crown diameter table is crusial task. This study describes a development of tree volume table and tree height curve of mangrove forest in PT. Bina Ovivipari Semesta area, West Kalimantan Province. The main study objective is to provide the best models for estimating standing tree volume and tree height. To achieve the study objective, a total number of 140 trees having various dbh size were selected purposively. All of the trees were felled, bucked, measured and calculated providing timber volume for each tree. From those tree samples, about 93 trees were randomly selected to develop estimation models, while the rest were used to perform validation test. On the statistical analysis, several tree volume and tree height models having simple, polynomial and multiple forms were examined and evaluated. This study found that the best model for estimating tree volume are V = 0.000064D2.93812210(- 0.00725xD) and V = 0.000021D3.4596710(-0.017984 x D) while the best model for estimating tree height is H = -1.6408+1.25458D–0.0097D2. This study concludes that tree volume and tree height curve for Rhizophora apiculata could be developed on the basis of diameter at breast height (dbh).

Judul: Penyusunan Tabel Volume Lokal Jenis Keruing (Dipterocarpus spp.) di IUPHHK-HA PT. Sarmiento Parakantja Timber, Kalimantan Tengah
Abstrak: In order for the forest sustainability can be ensured, need to do a good forest management plan, careful and accurate information and reliable. The information needed is data about the potential of forest stands. Potential prediction of forest stands are related to the timber volume prediction. To collect such information, then the forest inventory of activities needs to be done. One of the tools to simplify and accelerate the activities of forest inventory is the volume table. Prediction tree stand volume by using the volume table will be more efficient and save costs and time. The purpose of this research is to develop a local volume table of keruing (Dipterocarpus spp.) in the area of IUPHHK-HA PT. Sarmiento Parakantja Timber, Central Kalimantan. The table volume made is table volume premises with diameter of trees as high as the chest (Dbh) as free variables. The preparation of a volume table is done using three models a regression equation with a diameter as free variables. A model of an equation probe volume was selected from third best model the regression equation is based on criteria test statistics in the preparation and validation model. The test criteria, namely the coefficient of determination (R2), standard deviation (s), diversity analysis, refraction, aggregate deviation (SA), average deviation (SR), the Root Mean Square Error (RMSE), and mean difference test chi-squared (χ2). Based on these criteria, the model equations estimators keruing (Dipterocarpus spp.) is a model equation Berkout V = 0, 0003631Dbh2, 26 with the value s = 0,059, R2 = 98,70%, Fhitung = 4875,51%, bias = 14,81%, SA = 0,03, SR = 11,04%, RMSE = 19,12,% and χ2 = 1,37.
