Abstract

Acacia nilotica is an invasive species in the Baluran National Park. The spread of A. nilotica is a serious threat that can disrupt the function of savanna ecosystems in providing food for herbivores and eventually led to a decrease in wildlife populations of herbivorous. The growth of A. nilotica invasive species is influenced by some environmental factors. In order to prevent the spread of A. nilotica, a model can be formed to prodict the species distribution based on the environmental factors namely generalized linear models. This research used the data from Siswoyo’s research in 2014, which consisted of environmental data and distribution of A. nilotica. The results showed that there were five environmental variables that significantly affect on the spread of A. nilotica invasive species. The variables included elevation, surface temperature, normalized difference vegetation index, normalized difference moisture index, and the distance from the river, with p-value less than 0.05. The accuracy of the prediction model on the spread of A. nilotica using GLM was 97.22% and the Area Under Curve (AUC) value was 0.981.

Abstract

Independent smallholders who manage their own oil palm plantations without receiving technical assistance and agricultural inputs from oil palm estates or government have been  increasing rapidly in Indonesia in recent years. However the magnitude of their impacts on tropical forest deforestation remains largely unevaluated.  The objective  of this study was  to explore the history of land use, and the changes in land cover and status since the onset  of  oil palm plantation activities. The study was conducted from March to April 2016. Surveys  were carried out in 30 ha of independent smallholder oil palm in  Kampar District, Riau Province.  To identify the land status, the Agreed functional forest classification (TGHK) and Provincial land use planning (RTRWP) maps were overlaid on images of the area of independent smallholder oil palm. Landsat images three years before oil palm was established were used to assess forest cover changes.  Furthermore, oil palm smallholders and elders of the local community in the research area  were  interviewed to identify land use prior to oil palm.  Our results showed that, based on land  status, 47% of  the area of independent smallholders’ oil palm derived from logged forest; that is the land  changed in status from forest to oil palm plantation.  The other 53% of oil palm area derived from non-forested land. The land use history before the establishment of independent smallholder oil palm mostly comprised general-purpose field activities and former forest-felling (forest concessions). The land cover  before conversion into oil palm comprised rubber plantation, secondary forest, and shrub cover. From the results of our survey, we conclude that most of the oil palm plantations planted between  1990 and 2002 have their origins not in primary forest, but rather in  degraded secondary forest, former fields, and shrub-land. These results imply that conversion of forest area into oil palm plantations is not the direct cause of deforestation in the tropical forests of Kampar, Riau Province.

Abstract

Wehea forest is a highland of tropical rain forest on East Kutai Regency in East Kalimantan. The community especially Wehea ethnic in Nehas Liah Bing Village is well known for their traditional wisdom in utilizing the forest resources. Wehea Forest Area is a cluster of Maput and Pendreh land systems, and both land systems are irregular hilly regions that have steep to very steep slopes. Because of the uniqueness of biodiversity, landscapes, and traditional wisdom of Wehea ethnic the forest has been declared as forest reserve. This study aimed to assess the natural resources, culture, and participation local community as potential for nature based turism development. The result showed that the Wehea forest has biodiversity of flora dan fauna. Species of flora which are often founded are families of Dipterocarpaceae, Annonaceae, Lauraceae, etc. Fauna potentials are not less important and interesting than flora ones. There are several species which have endangered and protected status. The uniqueness of natural forest landscape really supports to various ecotourism activities. Wehea forest wealth also comes from local community presence. Their awareness is relatively high about Wehea forest existence, especially communities in Nehas Liah Bing. Dayak ethnic of Wehea forest has unique culture to be developed as tourist attraction. Dayak ethnic communities in Miau Baru are Kenyah and then community in Makmur Jaya which was once a transmigration village of Java ethnic. Both communities in the village are familiar about the Wehea forest existence. Culture value diversity, awareness, and participation of local communities become strong capital to develop natural based turism and are expected to contribute to economic diversification region.

Abstract

The topic of social capital has been gaining many concerns from social researchers throughout the world, especially in collective action perspective. This study aimed to describe the organizational activities of the local forest management practices (parak and rimbo) as a social capital in collective action perspective. The research method is a case study of Koto Malintang and Simancuang people in West Sumatra. Collecting data was conducted by unstructured interviews, field observations, and document studies. Data analysis uses categorization and coding, document analysis, and historical analysis. Our findings were described in the context of decision-making, resources management and mobilization, communication, and conflict resolution. Collective action for decision-making involved the acquisition, allocation, and distribution mechanisms to divide land and forest product among local people. In the context of resources management and mobilization, they applied kinship relations among families, sub-clans, and clans to manage their resources. They then communicated their needs in any formal and informal meetings. When a conflict occurred in related to forest utilization, they applied an adat court to make a win-win solution. Nevertheless, the challenges of collective action are still about the resources availability, benefit equity, and external supports

Abstract

Utilization conflicts among users threatening the sustainability of forest management. This study is to determine the intensity of conflict and the sustainability of forest management in FMU Meranti by integrating the convergent parallel mixed method and Rapid Land Tenure Assessment. Data was collected through interviews with key informants, literatures, maps, documents, and histories studies; as well as focus groups discussions in eight villages around the FMU Meranti. The results showed that the people's bundle of right, the interaction and social capital, dispute against the coorporation's financial modal. Generally, the interaction and social capital elements are owned by the local community, while the financial modal is owned by the permit holder and the local elite. Based on the power analysis on each object, the power of both community and permit holders are equally strong. The conflict intensity is subdivided into three conflict categories, i.e.: open (31%), appear (44%), and latent conflicts (25%). The special area (wilayah tertentu) and open access area are highly prioritized, that need conflict resolution. The existence of the environmental damages, unclear ownership rights, lack of stakeholder supporting, and non-optimal institutional performance lead the sustainable forest management to bad category (40.6%).

Abstract

Pine forest management today has not already reached its optimal state. The abnormal pine stand structure will cause a decrease in the production of pine resin. This study aimed to determine the optimal rotation of pine plantation forest and formulated the harvest scheduling to ensured optimal resin production. The determination of optimal rotation was conducted by modifying the Faustman formula to be applied on the condition in forest management in Perhutani. Simulation optimization of harvest scheduling was conducted by linear programming. Optimal rotation of pine forest plantation consists of timber rotation and resin rotation. The highest net present value of timber was obtained at 25 year cycles and the highest net present value of the resin was obtained at 35 year cycles. The inclusion of resin benefit was resulting in lengthening the optimal rotation age. The abnormal stand structure was causing the fluctuations of pine resin production. Thus, the efforts to improve it was by applying the harvest scheduling framework. This study concluded that harvest scheduling which conducted over eight periods has made the abnormal stand structure into the normal forest condition. The existence of normal forest condition led to the certainty of pine resin production sustainability.
