Allometric Equation Models to Estimate Biomass of Tropical Natural Forest in Papua

ABSTRACT


RAHMAD SUPRI ANGGONO. Allometric Equation Models to Estimate Biomass of Tropical Natural Forest in IUPHHK-HA PT. Wapoga Mutiara Timber’s Area, Papua. Supervised by ELIAS.

This research aims to create allometric equation models to estimate the biomass of tropical natural forests in eastern Indonesia. Allometric equation models made by destructive methods and using purposive sampling method to take 30 sampling trees. Best equation model to estimate tree biomass of this research consists of biomass tree parts model and total tree biomass model. Models to estimate the biomass of the tree parts such as W = 0.0245 D2,23 Tt0,74 to estimate the stem biomass, W = 0,0003 D3,91 Tbc-0,66 for the branch biomass, W = 0,054783 D2,42 Tt-0,63 for twigs biomass, and W = 0,0513 D1,62 for leaf biomass. The best model to estimate the total biomass is W = 0,0655 D2,52Tbc0,23 where W is biomass, D is diameter at breast height (cm), Tbc (clear bole), and Tt is the total height of the tree. This models have R2(adj) of 78,31 – 97,75% and the deviation (s) of 0,1337 – 0,3201.

How difficult am I ? Without no help from them (all my friends of our fieldtrip, and the employees of PT Wapoga Mutiara Timber II) 

I am grateful to Mr. Yancy (as my second fahter there) and his employee survey staff  of PT. WMT II, and Mr. Ferdianan and Forestry staff at PT. Salaki Mandiri Sejahtera, Papua. Also thanks so much to my special colleagues of one filedtrip group (Field Work Practice) : Bagus Rama Primadian (Bagus), Listya Nuriyana (Yana), Endita Priyasti (Endi), Hastuti Dyah Prajna Paramithasari (Mbak Tut), who have helped fully during field data collection. Expressions of thanks are also extended to the father, the mother, and the whole family, for all the prayers and affection. Hopefully, this research can be usefull

here is my documentary in my researching process
