Abstract

The paper describes economic valuation for the Cidanau watershed area of West Java in Indonesia. In this area natural resources deterioration has occurred even faster after the Asian Financial Crisis. The deforestation area and pronounced soil erosion seems to go unhindered because of land use competition among the residents for agricultural space, housing, etc. In order to prevent the area from further degradation, the purpose of this paper is to carry out quantitative evaluation which also attempts to raise the environmental awareness of residents, as well as visitors to the area. Questionnaire surveys were conducted and analyzed according to the Contingent Valuation Method (CVM) and the Travel Cost Method (TCM). The results show all respondents held good attitudes towards the efforts of environmental conservation, but responded negatively if they had to contribute to the environmental service payment. Visitors to the Anyer Beach acted differently because most of them come from faraway locations and have little knowledge of the watershed. However, the Anyer Beach recorded an environmental valuation of about Rp840 billion, which is a potential source for the service payment of Cidanau watershed.

Abstract

One effort in improving productivity and regaining the function of forest and land which have been degraded is national movement on forest and land rehabilitation (Gerhan). This movement constitutes an investment. In general, an investment should always involve the expectation for obtaining benefit/profit, either directly or indirectly. The objective of this research was to estimate the magnitude of total benefits value resulting from Gerhan in Sub Watershed of Tirto located in Central Java Province. Benefits value was calculated by using market price approach, replacement cost, procurement cost, and contingency valuation methods. Economic value which was calculated consisted of direct use value, indirect use value, and non use value (option value and existence value). From rehabilitated land, as large as 1,463 ha (planting year 2003–2008) in the Tirto sub watershed, the present worth total economic value resulted from was Rp331,223,929,621 with analysis period of 15 years (cutting cycle of woody crop) at interest rate of 15% or Rp15,093,367 ha-1 year-1. Such value consisted of direct use value 92.21%, indirect use value of 6.64%, and non use value of 1.15%. These benefit value was calculated on the basis of planting success rate, namely 88% for woody crops and 85% for multi purpose tree species.

Abstract

This paper aims to analyze the impact of non-forestry policy, especially energy related macro policy decisions, on poverty and use levels of natural resources. As core indicators, this analysis employs ‘number of households below the poverty line’ and ‘area of deforestation’. Impacts are analyzed in an agent-based simulation model for 6 districts of East Kalimantan, one of the Indonesian natural-resource rich provinces on the Island of Borneo. Simulation results partly suggest that the policy decision of June 2008-politically known as decreasing fuel price-had nearly no impact on deforestation amplifying that the dominating driver of deforestation is large scale logging and mining operations, as well as potentially illegal activities. While, it reduced the number of poor people-those mostly living within and around forest area-by about 5.4%. Due to seasonal income, this policy-related impact is likely to be periodically lower. During the harvest related period, many households are able to lift their income above the poverty line. This seasonal fluctuation in poverty could help optimize public funding by spreading it over longer periods and by pausing direct transfers during such natural periods of poverty reduction. There is no significant implication for forestry or forest management since the model could only deal with small scale forestry.

Abstract

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.

Abstract

This study was aimed to analyze the relationship between diameter at breast height, height, and volume of standing Shorea sp. and the relationship between age and volume of this species.  The study was conducted at different ages of rehabilitated forest in Bintulu Sarawak, where the measurement was taken from tree stand year 1992 until 2003.  The sampling plot of 20m x 20m was built for each age of stand. Ten standing Shorea sp. were randomly measured for sectionals (taper) from diameter at breast height until the free branches of the tree. The rest of the trees within the plot were only measured by diameter at breast height. All collected data were calculated to find basal area of each tree in meter square (m2).  The volume per plot was calculated using the Smalian’s formula to find the taper volume of the Shorea sp.  Statistical analysis was conducted to find the regression equation which could explain the relation between volume, diameter, and height of the tree.  Result showed that there was a relationship between volume, diameter, and height of the tree, and also there was relationship between volume and age of the tree.  Meanwhile, there was no relationship between taper of standing trees and age of trees. This means that volume taper of standing tree and age have no correlation.

Abstract

Javan rhinoceros (Rhinoceros sondaicus) is one of the rarest rhinoceros that are still existing today. Their distribution is limited to only a handful of countries including Indonesia, Vietnam, and possibly in Cambodia and Laos. In Indonesia, the species is only found in Ujung Kulon National Park (UKNP). Its population is concentrated in the Ujung Kulon peninsula. Theoretically, large animals have preferences in their habitat and therefore tend to distribute uniformly or clumped. In consequence, the management of javan rhino population and habitat must consider their habitat preference. The objectives of this study were: 1) to identify dominant habitat components that determine the presence of Javan Rhinoceros in UKNP, and 2) to formulate habitat preference typology. The study was carried out in Management Section II area of UKNP, Pandeglang District, Banten Province. Method applied was direct field observation and literature review.  Based on multiple linear regressions, the dominant habitat factors preferred  javan rhino were soil pH (X7) and salinity (X9). The equation formulated was  Y = 6.25 – 1.12 X7 + 3.88 X9.  Using Neu’s method of preferential index analysis, it was revealed that Citadahan, Cibandawoh, Cikeusik and Cigenter had preferential indices greater than 1.  The data shows that javan rhinoceros mostly prefer habitats located 400-600 m from the coast, and areas located 0-400 m was considered as their second preference.

Abstract

This study was carried out as one part of comprehensive research project aimed to increase sustainable management of forests and peatlands in Indonesia in order to increase the carbon sequestration capacity and community incomes.  The specific aim of the study was to  calculate  total value carbon gained as impact of various interventions in area of Ex-PLG Blok A, Mentangai, Central Kalimantan.  Estimation on carbon stock was conducted by Sample Plot of Measurement (PCP).  The interventions in this study was cannal blocking.  The study showed that activity of cannal blocking resulted in a positive impact, indicated by the present of reduction carbon rate (both above and below ground carbon), as well as carbon content by tree plantation (43,451 ha). Based on result of calculation, the amount of obtained above ground carbon stock was 14,448 ton C.  Carbon stock found in the tree plantation in surrounding the cannal was 0,777 ton C.  Below ground carbon stock was ranged between 550,782 ton C to 2,223,424 ton C. Total above ground and below ground carbon stock were 2,541,222.78 ton C or equal to 9,317,816.85 ton CO2.

Abstract

The objective of this study was to explain how local community in small islands can managed forest under population pressure, market intervention, and political dynamics. This study was expected to answer how community adapted with environmental change in forest management in small islands. The result of the study showed that community in Wangi-wangi Island has a unique forest management system based on community. It’s called kaindea. Management of kaindea done by sara (custom) and family and it’s used custom order. Environmental changes which are population pressure, market intervention, and political dynamics has influenced kaindea management. Public response as result of environmental change was responsed by reinforcement of social organization, adjustment of local agriculture technology, family jobs description, and expansion of livelihood. The study concluded that social organization (institution and social capital) has been very important roles on forest management and sustainability. It was suggested to have a further study about how orthogonal transformation in local institution passed to formal institute, by making community based forest management regulation, especially in customary forest.

Abstract

Jepara regency is the center for wooden furniture industries in Indonesia, and the products are generally marketed through a number of channels. Observed from the artisan to the last consumers, there were 5 common patterns of marketing channels in Jepara regency.  The structure of the furniture market in Jepara is segmented based on product, quality, and price, therefore this condition has resulted in the monopolistic competition market structure at artisan level and showroom (furniture shops).  Artisans of furniture in Jepara usually get the most orders in July, September, and December. The increase in furniture production was influenced by the religious celebrations of Idul Fitri and Christmas. The survey of furniture shops revealed that most raw materials used by the shops were half-done or unfinished furniture bought from the artisan. The best selling furniture design was elegant design with carved ornaments. In the meantime, the survey result of the households in Jepara which envolved households with permanent, semi-permanent, and non-permanent houses as respondents showed that each type had a different value in the process of searching for information concerning furniture models and places to buy furniture.

Abstract

The study of the effects of the clean activities of forest layers in logged areas on the increments of forest value comprises measurement by aerial photograph with scale of 1 : 20.000 and measurement in the field. The stand parameters measured are the percentage of crown cover (C), tree height (H) and crown diameters (D). Whereas, forest values are defined through the measurements of the amounts and qualities of rejuvenations counted after 1 year, 3 year, and 5 year of tidiness. The forest stratums resulted were Cl = 211.6 ha; C2 = 492.0 ha; and C3 = 196.4 ha. The t test conducted in every stratum showed that the tidiness affected significantly on the the amounts and qualities of rejuvenations. It could be concluded that the clean up activities increased the forest values.
