Model simulasi pengaturan hasil dinamik kasus di KPH Blora, Cepu dan Randublatung, Perum Perhutani, Unit I Jawa Tengah

Abstract

Pressure about forest resources can cause happen over exploitation until of forest resources not capable to give optimal benefit in fact on contrary, forest sustainable more offer decrease. The excalation of population in around forest area cause pressure about forest can effect to increase use area for settlement with construction wood and fuel wood consumption. The management of forest in Java Island which is whole almost of plant forest, at this time used one method of yield regulation of which is used in entire area of productin forest. This method only enter stand of forest factor, with the result of approach that currently used for aimed at method yield regulation of forest have the quality of partial. This research is aimed to arrange dinamics yield regulation of forest method in KPH Blora, Cepu, and Randublatung and study wood consumption effect for model of yield regulation by used. According to result khi-square test (X2) for KPH Blora shows X2 hitung 3,77 and values X2 tabcl shows 16,92 on confidence level of 95% by degrees of freedom 9. X2 hitung values more liitle than X2 tabcl can be conclusion that variability of simulation data not difference evidence with variability of actual data. For KPH Cepu according of result khi-square test (X ), shows X2 hitung 9,15 and X2 tabcl 16,92 on confidence level of 95% by degrees of freedom 9. X2hitun2 values more little than X2 tabcl, can be conclusion that variability of simulation data not difference evidence with variability of actual data. For KPH, Randublatung shows X2 hitung 3,31 and values X2 tabcl shows 16,92 on confidence level of 95% by degrees of freedom 9. X2 hitung values more liitle than X2 tabcl, can be conclusion that variability of simulation data not difference evidence with variability of actual data. According to scenario influence of construction wood and fuel wood consumption to fluctuation wood production (etat volume), sum of tree steal and enterprise profit in each KPH of result that : at KPH Blora of simulation result during 20 next years shows increase fuel wood consumption 50%, consequence of decrease etat volume 13.593,31 m or 3,34 %; increase sum of tree steal shows 66.176 tree and decrease KPH Profit shows Rp 12.158.321.453,- or 6,57.
