Penafsiran Volume Pohon Pinus merkusii melalui Foto Udara (Studi Kasus BKPH Majenang, KPH Banyumas Barat)
Abstract: The study aims to
compile and analyse the growing stock volume of Pinus merkusii by using stand
parameter measured through aerial photographs. The study was conducted by using
black-white panchromatic aerial photographs produced in 2005 and the scale was
1 : 20,000. The study was conducted in Pinus merkusii taping plots in the
Majenang BKPH, under the forest districts of west Banyumas, Perum Perhutani
using tree height, crown diameter and number of trees per hectare as
parameters. Data analysis was done to define the relationship among these
parameters in regression equation. The steps of the study were defining
measurement plots in aerial photographs, measurement of stand parameters in the
aerial photographs and field observation. Data analysis was performed using
micro computer. As a result, the regression equation for each location as
follows: V = 72,415 – 0,231 N + 35,242 H – 24,454D – 0,923 (N x D), with the
determination coefficient was 0,789 and the significance of 95%. Where: V =
growing stock volume (m3), N = the number of trees per hectare, H = tree height
(m) and D = crown diameter (m). It was concluded that number of tree per
hectare, tree height and crown diameter were good predictors for standing stock
volume of Pinus merkusii.
