STUDI PENERAPAN METODE POHON CONTOH (TREE SAMPLING) DALAM PENDUGAAN POTENSI TEGAKAN HUTAN TANAMAN EKALIPTUS

Management and exploitation of forest products required for planning to be prepared
for sustainable forest exploitation and also taking into account aspects of
Sustainability. The so-called aspects are production capabilities, ecological functions
and social functions. In order to achieve these matters, appropriate data are needed
to present information on the potential for existing forest stands through forest
inventory activities. In the inventory activity found some problems that occur in terms
of cost, time, problems and human resources needed. Factors that will affect the data
we get. These inhibiting factors can be overcome by creating three groups using
methods that have been developed both in data retrieval techniques and data
processing.The sampling method as a suitable and effective method in which the
sampling method used in the inventory activity is a conventional method using a plot
or a circle plot with the area and sampling determined according to the age class of
the stand. In addition, using conventional methods is another method that also has
accurate and precise information. Method of sampling trees. This study aims to the
effectiveness and effectiveness of tree sampling methods and circular plot methods,
making it easier to find an efficient and effective location in the work area of PT.
Perawang Sukses Perkasa Petapahan District. The research was conducted in the
plantation of industrial plant Ekaliptus (Eucalyptus pellita) located at PT. Perawang
Sukses Perkasa Industri Petapahan District, Kampar District, Riau Province. This
research was conducted for 2 months ie in May - June 2018. Based on the results of
research conducted method of circular plot will be more effective and has a higher
level of accuracy than other methods with a value of 2.9% sampling error. When
viewed from a relative point of view, the relative average yield using the tree
sampling method of 8 trees is more easily done in a circular manner with a relative
value of 200.28% and accuracy is still accountable.
