Growth Model of Pine (Pinus merkusii Jungh. Et de Vriese) Stand on Community Forest in Tana Toraja Regency

Growth modeling and yield simulation of forest is a very important aspect in forest management including community forests. Stand growth model is an abstraction of the dynamic nature of a forest stand, including growth, ingrowths, mortality, and other changes in the structure and composition of the stand. In forest management, growth estimation plays an important role in supporting the sustainability of the benefits value of the community forests. The objectives of the research were to find out the stand growth model and the potential of community's pine forest. The study was conducted at the location of the community pine forests in District Mengkendek Tana Toraja Regency. Sample location, as representative of stand age classes that distribute on some villages in Mengkendek District, were selected by purposive sampling.The study results indicate that the most suitable model for upper trees mean height (H) is Weibull Model, for growth diameter and growth volume is Logistic Model  . The stand mean height (h) can be presented as a function of H and Relative Spacing Ratio (Sr) on the basis of function log Sr = 0,197 – 0,653 log H, then the tree volume, can be estimated on the basis of function log V = -1,70 + 0,94logD + 1,50logh, and then the growth function of volume on the basis of function V = 1.008 / 1 + 251.322 exp(-0.373t. Further, the maximum value of stand Annual Increment was 18 m3ha-1year-1, attained at the age of 20 years

Application of the Brandis Method for Yield Regulation of Pine Private Forest in Tana Toraja

The utilization of private forests in Indonesia that is not managed properly based on the principle of sustainable yield will result in the depletion of private forests in the not too distant future. Therefore the sustainability of private forest is a necessity that cannot be delayed anymore. The general objective of this research is to find out whether the yield regulation method (Brandis Method) can be applied in private forests. The specific objectives of this study are: (a) to analyze the characteristics of pine private forests and their suitability for the Brandis Method practice, and (b) to know the sustainability of pine forest products in Tana Toraja using the Brandis Method and its institutions. The data collected in this study consist of primary and secondary data. The analytical method used was descriptive analysis and yield regulation method was analyzed based on Brandis Method. The result of this study shows that the yield regulation of the private pine forests in Tana Toraja can be done based on the number of trees using the Brandis Method. The regulation of private forest products based on the number of trees can be carried out if there is support from private forest institutions

Strategi Pembangunan Hutan Rakyat Pinus di Tana Toraja

The exploitation of pine people forest in Tana Toraja has just begun since pine wood manufacturing industry opened in 2002. In 2004, the activity of this manufacture was stopped as some local people protested the activity. They assumed that the exploitation and manufacturing would cause negative effect, as the stand value could be much higher than benefits of the industry. In 2006, Tana Toraja Regency Government allowed the exploitation of the pine tree and offered the investors who were interested to invest their capital in the exploitation. The exploitation certainly needed a strategy based on accurate and comprehensive data.  The aim of this research was to arrange a strategy of pine people forest exploitation which could give both economy and ecology benefits. This research used financial analysis, SWOT analysis, and Analytical Hierarchy Process.  The result of the analyses indicated that the strategy could be best applied was strength-threat (ST) by increasing the role of farmer organization, conducting agroforestry pattern development in order to increase land productivity, applying proper regulating area for planting and harvesting, and assuring the exploitation of tongkonan area

Stem Biomass Equation of Eucalyptus urophylla S.T. Blake

Eucalyptus urophylla is one of the typical plants of the Province of East Nusa Tenggara,  Indonesia whose distribution includes the islands of Timor, Alor, Wetor, Flores, Adonara, Lomblen, and Pantar. The best land for the growth of E. urophylla is an area with rainfall above 1000 mm every year. E. urophylla dominate the island of Timor hence the potential to absorb carbon and store it in biomass as part of climate change mitigation. This study aims to determine the allometric equation model to predict the potential of E. urophylla stem biomass. Calculation of the amount of stem biomass based on allometric equations is an analytical method used in this study. The sample trees used in equation modeling is 100 trees as a result of the inventory. The equations that can be used to estimate the biomass potential of the stem of  E. urophylla in Timor Island were ln  = -2.12 + 2.472 ln ( ) and (R2= 0.98); ln  = -3.617 + 1.046 ln  and (R2= 0.99); and ln  = -3.510 + 2.157 ln ( ) + 0.983 ln  and (R2= 0.99). The stem biomass potential with the model I amounting to 276.877 tons ha-1, model II of 279.671 tons ha-1, and model III of 280.209 tons ha-1
