Potensi Produksi Arang dari Hutan Rakyat Desa Bangunjiwo, Kecamatan Kasihan, Bantul, Daerah Istimewa Yogyakarta
Abstract: Asam jawa
(Tamarindus indica) and mahoni (Swietenia macrophylla) which predominantly grow
on the community forests of Bangunjiwo Village are an ideal candidate as raw
matterial of charchoal production because they're hard wood makes good quality
charchoal and income from its charchoal are an attractive source of
supplemental revenue. Information on its charchoal production are needed, but
this information is currently lacking. The potential of charcoal production of
woody perennial in the community forests were estimated by developing
allometric equations for standing trees. To establish the equations 30 sample
logs of tamarind and 29 sample logs of mahoni were made charcoal by traditional
kiln to determine the relationships between the mechantable timber volume/log
(Vkp) and its charcoal production (Pa). The raw material of charcoal production
from the merchantable timber volume in the community forests was the ligneous
material contained in the bole and branches which both with a diameter of at
least 7 cm. The results showed that the merchantable timber volume was strongly
related to the charcoal production (tamarind: Pa = 185.6180 (Vkp)0.9455, n =
30, r2 = 0.9559; mahoni: 321.2263
(Vkp)1.0725, n = 29, r2 = 0.9459; mixed:
= 235.0601 (Vkp)1.0008, n = 59, r2 =
0.9465). The potential of charcoal production in the community forests was then
estimated based on the allometric equations. The potential of charcoal
production in these community forests was 12.067 ton/ha, equal to Rp 21.117.250,00 /ha which contributing the
forest to the regional income.
