Local Volume Table For Rhizophora Apiculata At Matang Mangrove Forest Reserve, Perak Darul Ridzuan In Peninsular Malaysia

Abstract

Mangrove forests are a productive and rich natural resource that benefits local economies and societies. The objective of this thesis is to develop a simple tree volume equation as to be used in the construction of Local Volume Table (LVT) for Rhizophora apiculata at Matang Mangrove Forest Reserve. Diameter at the Breast Height (DBH) and merchantable height was collected during inventory. For the purpose of volume table development, all trees (n-196) were felled and sectional diameter every 1.6 meter was measured. Volume for each trees then calculated using Newton’s formula. Statistic test such as liner regression correlation and F test were used to determine the relationship between diameter and volume and also to estimate the parameter for volume equation. There for Standard Volume Table (SVT) was develop to compare between a new and old volume equation to determine relationship between diameter and volume equation. The result for LVT show the best of estimation is designation I is a form of Log, the type is LnV = a + LnD, the R² is a high, Volume Over Bark 0.962 and Volume Under Bark 0.916, F test from ANOVA table show be able to significant. There are the result for SVT show the best of estimation is designation I is a form of Power, the type is V = a Dᵇ Hᶜ, the R² is a high, Volume Over Bark 0.980 and Volume Under Bark 0.979, F test from ANOVA table show be able to significant. Compare Mean Absolute Percentage (MAPE) for validation data LVT and SVT is result are insignificant (p > 0.05), p-value LVT
