Abstract

The utilization of land together between trees and crops is one of the strategies in land rehabilitation program in Indonesia. High pressure from people living surrounding the forest land required the forest managers to invite more participation from the people in managing the forest land. Agroforestry pattern with certain tree species chosen by forest managers together with certain crops preferred by the communities may become the solution for all stakeholders’ interests in a high-pressured forest area. One of the considerations in agroforestry development is economic aspect. This study aims to analyze the financial feasibility of agroforestry pattern auri (Acacia auriculiformis) and peanut, pigeon pea, and corn in Batulanteh forest management unit (FMU) in Sumbawa, West Nusa Tenggara. The feasibility assessment criteria used in this study were Net Present Value (NPV), Internal Rate of Return (IRR) and Benefit Cost Ratio (BCR). The result of this study showed that agroforestry pattern of auri with paddy, peanut, pigeon pea and corn is financially feasible with the NPV, IRR and BCR values are IDR14.607.837.-, 53 % and 1.51 respectively. Keywords: agroforestry, paddy, peanut, pigeon pea, corn, dry land

Abstract

In the forest economics literature, Faustmann formula is highly adopted for profit maximization problem in forest management, mostly in plantation forest. Stylized models of Faustmann formula to be applied in selective logging regime have also been studied extensively in multi-age and multi-species forest. In general, natural forest managers in Indonesia have not adopted the Faustmann formula in their management decisions. Sustainability aspect in natural forest management is applied based on silvicultural consideration, i.e. measuring residual stand that is able to be harvested in the next cutting cycle. This study aims to analyze the application of Faustmann formula in the current selective logging regime in Indonesia (i.e. TPTI), so that the natural forest managers may gain maximum profit and sustainable. This study is a qualitative research based on literature review. The results of this study show that under deterministic growth model (i.e. matrix transition model) and robust damage model (i.e. transition matrix with different damage proportions on each species and diameter class), the Faustmann formula can be applied for selective Logging regime in Indonesia.Keywords: Faustmann formula, selective logging, natural forest, Indonesia
