Determining Harvest Time of Balangeran Plants (Shorea balangeran Korth. Burck) Using Rational Model

Wahyudi, Petrus Poerwadi, I Nyoman Sudyana, Johanna Maria Rotinsulu

Abstract: The balangeran tree (Shorea balangeran Korth. Burck) is a commercial species that grows well in peat swamps. Plant growth can be described through mathematical equations. The research aims to determine the most appropriate harvest time for balangeran plants using rational equations. The model was then tested for validation, accuracy and coefficient of determination. The results of the research show that the diameter growth model for balangeran plants using a rational equation is namely: y = - 6.94 + 7.26 x / (1+ 0.48 x + (-0.01) x2) with a coefficient of determination of 80%, The equation is valid and quite accurate. Based on this equation, the harvest time for balangeran plants can be determined, namely 29 years, when the average diameter of balangeran plants reaches 30.97 cm.
