Model Penduga Non Destruktif Produksi dan Nilai Ekonomi Minyak Eukaliptus

Abstract

Eucalyptus is one of the selected plant species in developing Industrial Plantation Forests (HTI) as a producer of raw materials for the pulp and paper industry, which can be harvested at five to seven years old. Eucalyptus stems are raw material for paper and other industries, but the leaves are still wasted. Meanwhile, the issuance of Minister of Environment and Forestry Regulation No. 8 of 2021 requires all forest managers to implement multi-forestry businesses. For Eucalyptus HTI managers, one of the main potentials of their multi-forestry business is using essential oils from logging waste leaves. This research aims to 1 create a mathematical model that estimates the production of non-destructive essential oils produced from Eucalyptus leaves and 2 make a mathematical model that estimates the economic value of non-destructive essential oils produced from Eucalyptus leaves. The stages of this research method are conducting field observations/measurements, literature studies and comparisons, measuring leaf yield, and testing data using simple linear regression analysis and classical assumption testing. Based on the results of the analytical tests that have been carried out, a model for estimating eucalyptus oil production is obtained, namely, Y = -0,586 + 0,185 X , and a model for estimating the economic value of eucalyptus oil, namely, Y = -439,357. Apart from that, the coefficient of determination of production and economic value of eucalyptus oil is 0,163. This means that 16,3% of the variation in the independent variable (dbh) can explain the dependent variable (production and economic value of eucalyptus oil). Meanwhile, the remaining 83,7% is explained by other factors outside the research model.
