Abstract

Arboretum as one example of ecosystems that have the diversity of flora and fauna requires good management, so as to provide benefits to the surrounding environment. Biological diversity (biodiversity) that exist in the Arboretum area is quite high. This is because the Arboretum has many species which are usually brought in from outside, then planted and maintained as a collection of plants for various purposes of academic activities, in addition to local species that live naturally in the Arboretum. Limited funds arboretum management and level of understanding about the functions and benefits of some of the arboretum, arboretum resulted in the existence of a very minimalist. This issue will greatly affect the existence of the arboretum in the future.The purpose of this study are aware of the economic value of the existing flora and fauna in the Dipterocarpaceae arboretum and get the benefits of environmental services for the around arboretum. Economic valuation of the timber is done by using the market price approach. To obtain economic value of wood made a simple calculation that the total timber volume multiplied by price per unit of wood. While the economic value of air services is divided into two parts namely the absorption of carbon dioxide by the market price method and coolness by using surrogate price method. Value of economic in Unilak dipterocarp arboretum of Rp. 15,538,672,849.13 consisting of timber economic value of Rp. 385,843,912.00 and the coolness of the economic value of Rp. 15,137,500,000.00 and carbon uptake value of Rp. 15,078,937.13. The economic value of benefits in the form of services (intangible) greater (97.52%) than the value in the form of objects (tangible) (2.48%).

Abstract

The forest inventory is basically a data collection activities. This activity is relatively important, because the effect on further activities. Hence the data collected must have a high enough accuracy. A way of determining the sampling unit is considered to be simpler, easier, and faster is the tree sampl ing method. The purpose of this study was to quantify the potential large stands of eucalyptus in the Forest of eucalyptus plants in the Faculty of Forestry and calculate the relative efficiency of sample unit. The total area is 0.11 ha of eucalyptus stands. Unit examples used are circular, 4-trees sampling, sampling 5 -trees, and 6-trees sampling is done by simple random sampling method. Potential stands of eucalyptus with method 6 sample trees have an average volume stands perplot is 0.07 m3, with the volume of the stand for the entire area is 84.71 m3 with a sampling error of 36,96%. Potential stands of eucalyptus trees by the method of example 8 trees have a volume average stocking each plot is 0.04 m3, with the volume of the sta nd for the entire area is 43.22 m3 with a sampling error of 51.47%. Potential stands of eucalyptus by using 10 sample trees have an average volume stands each plot was 0.03 m3 with the volume of the stand for the entire area is 39.74 m3 with a sampling error of 53.34%. Potential stands of eucalyptus with a diameter circular sample plots of 12 m has an average volume stands each plot is 7.88 m3, with the volume of the stand for the entire area is 76.72 m3 with a sampling error of 14.43%.

Abstract

The research objective was to determine the level of understanding and perception of forest communities against carbon trading and determine the factors that influence the understanding and perception of forest communities on carbon trading. The experiment was conducted for six months (February 2015 -July 2015), involving 60 respondents from community leaders and ordinary citizens from four villages namely Sungai Rawa village, Rawa Mekar Jaya village, Penyengat village and Teluk Lanus village in the region Sungai Apit district of Siak, Province Riau with a survey method that is divided into two activities: (1) Focus Group Discussion (FGD), and (2) structured interviews with villagers. The study states that the majority of respondents (58.49%) stated that they had never heard of the term climate change / REDD / carbon trading. The majority of respondents (50.00%) did not give an answer on the form of institutions that have the potential to implement carbon trading activities, while other respondents (12.50%) expressed the need for training for members of the institution designated to implement the REDD + activities. Understanding of society remains low and the perception of the public is still in doubt with this activity becau se it has not seen examples of activities that have been successful. Factors associated with a real understanding in relation to carbon trading activities are education and perception. Results of other studies conclude that there is a significant correlation between education and perception.

Abstract

Industrial plantations are production forests that have monoculture species (1 species), which take up to 5 years to be ready for harvest. Before harvesting, activities are carried out it is necessary to analyze the cost of harvesting,where the aim is to find out the magnitude of the profits obtained by the company. The purpose of this study is to analyze the cost of harvesting and analyze the productivity of wood from harvesting activities at HPHTI PT. PSPI Petapahan District. This research was conducted in May - June 2019. The sampling method in this study used a purposive sampling system. Based on the results of research conducted at PT. PSPI Petapahan District, the production costs for harvesting are activity are obtained, the amount of costs for felling and dividing the stems of IDR 27.235/hour, the costs for stacking IDR 200.584/hour, costs for stripping bark of IDR 203.991/hour, costs for skidding IDR 204.091/hour, the fee for loading and unloading skid is IDR 200.584/hour and the cost for loading to truck is IDR 200.584/hour. While harvesting productivity for each activity is felling productivity of 20,97 m3/hour, division of stems of 35,25 m3/hour, stacking of 21,10 m3/hour, stripping bark of 39,50 m3/hour, skidding of wood by 21,23 m3/hour, skid loading and unloading of 49,61 m3/hour and loading to trucks of 12,40 m3/hour.
