Judul: Model Simulasi Pengelolaan Hutan di KPH Bandung Utara Perum Perhutani Unit III Provinsi Jawa Barat
Abstrak: Perum Perhutani a State-Owned Enterprises (SOEs) operating in the forestry sector, Perum Perhutani manages state assets in the form of Protected Forest (PtF), Producted Forest (PdF), or Limited Producted Forest (LPF). Kesatuan Pemangku Hutan Bandung Utara (KPH BDU) is part of Perum Perhutani and duty to manage the forests in the KPH BDU area. In managing forests, KPH BDU seeks to synergize the elements of economic, social, and environmental. However, its implementation has not been achieved economic sustainability, KPH BDU in the last three years (2009 - 2011) was a loss in the balance sheet. With the condition of the majority of forest status status is certainly achieving sustainable economic PF challenged, given the commodity Perum Perhutani generally is wood. As a business entity, KPH BDU would seek to make a surplus in its balance sheet in order to achieve economic sustainability. Various ways have been done KPH BDU in order to achieve economic sustainability, including making nonwood forest products (NTFPs) as a commodity to be managed. This study aims to create a simulation model of forest management by KPH BDU, the model simulated in order to provide the best recommendations related to the management of forest commodities in the majority of the forest area protected status. In making the necessary simulation model Stella modeling software version 9.02 and Microsoft Excel 2007, the data are analyzed for the formulation of a conceptual model is intended to obtain forest management model. Once the model is developed quantitative model specification needs to be done to put the equation into a quantitative model. Evaluation model to assess the reasonableness of the model when the parameters changed in the extreme. Certain scenarios can be created in the final process modeling is the use of the model. Based on the results of research known commodity that will provide a positive impact on the economic sustainability of northern Bandung KPH is environmental services, agro-forestry, and non-essential businesses. While commodities are negatively impacted wood and sap pine (Pinus merkusii Jungh.). The best case scenario in managing forest commodities is to use timber and nontimber forest scenario option that gives surplus on the balance sheet.

Abstrak: Forest management simulation model in KPH Bojonegoro is an activity to make a model of forest products management both timber and non-timber has been developed by using several scenarios with the hopes of increasing revenue KPH Bojonegoro with a period of 2012 to 2021. This research was proposed to arrange and to make forest management simulation model and also to determine the best forest management in KPH Bojonegoro trough making some forest product scenario. In making the simulation model, it needs modeling software called Stella 9.02 and Microsoft Excel 2010. The results of this research shows that forest management scenario which only utilized timber apparently produced the lowest value of NPV Rp694 361 428 and BCR 1.12 (skenario I), where as forest management scenario that have the largest NPV value is timber forest management products scenario, non-timber forest products and environmental services with a value of NPV Rp 6 849 280 600 and BCR 1.28 (scenario IV) .
