\n In mathematics, the diameter is defined as a straight line through the center point of a circle.<\/span> Based on the understanding that the measurement of the diameter in the forestry sector, especially in geometry timber is carried on a tree stand, part of the tree is cut and branches.<\/span> Diameter measurement is important because it is a dimension that can be directly measured and the diameter can be determined from the cross-sectional area of trees \/ basal area and volume of the tree.<\/span><\/p>\n

Anonymous (2011) provide an understanding of the diameter as a fundamental dimension of the circle.<\/span> Thus the trunk diameter can be defined as the length of the line between two points on a circle around the stem through the center (axis) of the stem.<\/span> Diameter rod into the dimensions of the tree stands are most easily measured because the measurement is performed at the bottom of the tree.<\/span> However, the shape of the tree trunk generally has narrowed to the top end (taper), then from a tree can be obtained infinite number of values stem diameter corresponding number of dots on the base of the stem to the tip of the rod.<\/span><\/p>\n

Therefore the need to set the location of stem diameter measurements will characterize the characteristics of a tree.<\/span> On that basis ditetapkanlah diameter at breast height or dbh (diameter at breast height) as a measurement standard trunk diameter.<\/span> There are at least three reasons why the diameter measured at breast height elevation, namely:<\/span>
\n (A) The reasons of practicality and convenience when measuring, the measurement is done without having to bend or tiptoe.<\/span>
\n (B) In most trees at breast height elevation free from the influence of the buttresses.<\/span>
\n (C) The diameter at breast height (dbh) generally have a fairly close relationship with variables (dimensions) other trees.<\/span><\/p>\n

In practice dbh measurements, there are differences among some countries about chest-high altitude, namely:<\/span>
\n (A) State the metric system of measurement, dbh = 1.30 m above ground level (dat).<\/span>
\n (B) USA and Canada, dbh = 4 ft 6 in = 1.37 m above ground level (dat).<\/span>
\n (C) the United Kingdom and some Commonwealth (British system of measurement), dbh = 4 ft 3 in = 1.29 m above ground level (dat).<\/span>
\n (D) Japan, dbh = 4 ft 1.2 in = 1.25 m above ground level (dat).<\/span><\/p>\n

(2) Area of the base plane (LBDs)<\/strong><\/span>
\n<\/strong> Ash’ari et al.<\/span> (2012) in his book had explained the formula or calculation of basal area (cross-sectional area) tree.<\/span> Formulator or for an area basis in principle refers to the size of the diameter, but the reality on the ground is generally the calculation of basal area using girth.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
