An Object Driven Model of Above-Land Merkus Pine Tree for Quantifying the Commercial Contribution With Functional-Structural Plant Modeling

Abstract

The Merkus Pine tree is awfully prevalent in Indonesia, especially for its role in reforestation efforts. Beyond its academic significance, it carries economic importance for local communities and the nation at large. This study aims to establish an object-oriented model of the Merkus Pine tree, concentrating on its above-ground attributes. This object-oriented model-developing approach is integrated with the functional-structural plant modelling (FSPM) technique. The constructed model, referred to as an objectdriven model, has achieved a verification and validation value of 1.00. This model enables the simulation of the Merkus Pine tree's growth and development, encompassing both its physical structure and economic contribution. The simulation outcomes highlight that a single Merkus Pine tree, upon reaching fifteen years of maturity, can yield an economic contribution of approximately IDR 47,980.04. Also, the developed virtual model of the Merkus Pine tree can be operated as a green lab to analyze its growth and development being interconnected to other aspects; e.g. environment, politic, and culture.INDEX TERMS Merkus Pine tree, economic contribution, object-oriented approach, functional-structural plant modelling.
