Bogor Regency is one of the area with high landslide potential due to rainfall. High population growth and inappropriate spatial planning in Bogor regency were factors which led to increase risk of landslide. This risk would be more aggravated when community was completely unaware of and not responsive to the potential for landslides in the area. Related to this issue, it requires a comprehensive effort to reduce the risk of landslides, such as analysis of the vulnerability to landslides. The purpose of this study was to map the distribution of landslide prone areas in Bogor Regency and to evaluate the spatial pattern based on the landslide vulnerability in Bogor Regency.
The research was conducted in July – September 2011, with study sites for observation and data collection in Bogor, West Java. The materials used in the research are the images and maps of Bogor Regency in various layers. Landslide vulnerability was analysed based on the prediction model from Indonesian Center for Agricultural Land Resources Research and Development (ICALRD 2009). The parameters used to determine the level of vulnerability were the land cover, soil type, land slope, rainfall, geological formations and the vulnerability of ground motion. Each type of map was classified based on the scores, weighted and overlaid. Bogor Regency spatial pattern was then evaluated based on the Landslide Vulnerability Map.
Analysis based on the ICALRD (2009) Model of Vulnerability Landslide Prediction resulted in three classes of vulnerability to landslides in Bogor Regency, i.e. class of low vulnerability to landslides with an area of 94.991 ha (31.7%) covering 33 districts, class of middle vulnerability to landslides with an area of 173.309 ha (57.8% ) covering 36 districts and classes of high vulnerability to landslides with an area of 31.127 ha (10.396%) covering 28 districts. Results of the evaluation of spatial pattern indicated that some designated residential areas were located in areas with high vulnerability to landslides, which was not appropriate for uses as residential area. In addition, the evaluation also found utilization of areas which violated the designated spatial plan of Bogor Regency, in which conservation and protected forest areas with the function to protect the surrounding environment from landslide had been converted to residential area, plantations, ricefield and farm.

Abstract
Synthetic Aperture Radar (SAR) is a multipurpose sensor that can be operated in all-weather and day-night time. Conventionally, the SAR sensor has been operated in linear polarization with limited retrieved information. In this research, we are developing Circularly Polarized Synthetic Aperture Radar (CP-SAR) sensor for unmanned aerial vehicle and small satellite for Earth diagnosis. Comparing to linear polarized systems, the CP-SAR sensor has the advantage of compactness and low power requirement, since the transmission of CP microwave is not affected by the Faraday rotation effect in the ionosphere. In this presentation, the applications of synthetic aperture radar images for disaster monitoring by using Differential Interferometric Synthetic Aperture Radar (DInSAR) technique are also introduced.

Abstract: This study examined the relationship between backscatter magnitude of ALOS PALSAR images having several spatial resolutions (6.25 m, 12.5 m and 50 m) and variation of vegetation and forest variables. The study was performed in secondary natural forest, Eucalyptus plantation forest, rubber plantation and oil palm estate crop in North Sumatera Province. The study was focused to examine several stand and/or plantation variables that affect the variation of backscatter provided. The stand variables examined includes crown diameter, crown height, crown density, crown closure, stand density, tree diameter,basal area tree height, leaf area index, tree biomass for every size of tree (sapling, pole and tree levels). The main purpose of this study was to identify the most significant factors that affect the magnitude of backscatter within each type of forest cover and to develop biomass estimator model using backscatter derived from ALOS PALSAR. The study found that the variation of forest or vegetation variables may affect the variation of backscatter. For secondary natural forest, the study found that the stand variables giving significant influences on backscatter variations is the biomass volume and basal areas either for resolution 50 m x 50 m or 6.25 m x 6.25 m. However, for the Eucalyptus grandis plantation forest, the magnitude of bacskcatter is strongly influenced by stand height for resolution 50 m x 50 m; and stand density and crown closure for resolution 6.25m x 6.25m. For rubber plantation, the value of backscatter is strongly influenced by basal area tree diameter size (similar to natural forest) for resolution 50 m x 50 m; and by biomass, crown area, dbh and tree spacing ratio for 12.5 m x 12.5 m. . The value of backscatter in oil palm is influenced by crown diameter for resolution 50 m x 50 m and by tree height for 12.5 x 12.5 m. The study also found that bacscatter of ALOS PALSAR can be used to estimate the biomass content of rubber and oil palm. |

Aim Comparisons among islands offer the opportunity to study the effects of biotic and abiotic factors on small, replicated biological communities. Smaller population sizes on islands accelerate some ecological processes, which may decrease the time needed for perturbations to affect community composition. We surveyed ants on 18 small, tropical islands to determine the effects of island size, isolation from the mainland, and habitat disturbance on ant community composition.

C0MPARATIVE STUDY ON DECENTRALIZATION & PRIVATIZATION OF FOREST MANAGEMENT IN DEVELOPING COUNTRIES
Foreword (by. Prof. Misa Masuda, Tsukuba University)
This research project was conducted from April 2001 to March 2005. We selected three countries to study: China as a case of centralized forest administration system, India as a case of decentralized one, and Indonesia as a case in transition. These three countries alone indeed have dominated the world’s population, 40.1 percent in 2002 (UNDP, 2004), while the total land area and forest cover accounting for 10.8 percent and 6.0 percent respectively in 2000 (FAO, 2001). How to realize the compatibleness of growing population pressure and the scarcity of natural resources have been one of the key issues for developing countries, and the outcome of the policy measures of these three countries may affect not only the domestic environments but also the environments of surrounding countries.
The members of this project have diverse specialties: forest economics, political science, social ecology, forest ecology, and soil ecology in regard to the discipline, and also various research careers in Asia, Africa, and South America. Therefore, the results could not be compiled as an interdisciplinary study on specified topic and location.
Although the discussions are incomplete and many data still remain unprocessed, yet it is expected to be helpful leads to finding impacts of the ongoing political process of decentralization or centralization. Decentralization as a whole has been urged since longer before, and recent tones on forest

Master Thesis : Sustainable Management of Forest By Enhancing The Value of Medicinal Plants: A Case Study in Gunung Walat Educational Forest, Bogor Agricultural University
| Ellyn Kathalina Damayanti, E.Amzu, LB.Prasetyo Gunung Walat Educational Forest (GWEF) is one of field laboratories of Bogor Agricultural University (IPB), Indonesia. Faculty of Forestry is the manager and has been searching some sustainable ways to manage the forest. Unfortunately, there are lack of basic information on GWEF, especially related to biological diversity resources. The thesis is aimed at completing the basic information of GWEF. Especially on medicinal plant and establishing a sustainable management model of GWEF and mechanisms of reward for environmental service provided by surrounding communities. The field research was at Gunung Walat Educational Forest, conducted from May to July 2002. Data analysis, literature study and thesis writing were conducted in university of Tsukuba (Japan), from September 2002 to July 2003. Method used were: (1) forest-floor vegetation analysis, (2) interview with surrounding community and stackholders, and (3) Geographical Information System (GIS). Gunung Walat Educational Forest is a 350 ha-hanmad forest, which consist of 6 major tree stands from genus Pinus, Acacia, Schima, Agathis, Swietenia and Albizzia. The forest-floor Vegetation Analysis resulted in 85 species of forest-floor vegetation, which belong to 46 families. Seventy species of them belong to medicinal pants. According to the interview with surrounding communities, there are 177 species of plants they use for medicines. Only 20 species are found in GWEF, but they utilize only 3 species from GWEF : Achasma megalocheilos Griff. For asthma, costus speciosus (Koen) J.E. Smith for rheumatism, diabetes, diuretic, etc., and Selaginella plana Hieron for treatment after giving birth. Interview with stakeholders: Manager of GWEF, Local Government Research and Planning Agency, forestry Service, and Health Service of Sukabumi regency, surrounding community, and visitors resulted in their opinion that GWEF must be conserved and best utilized as a sustainable tourism area. Mapping with GIS resulted in spatial distribution of medicinal plant in GWEF. Each stand has a specific realtion with medicinal plant found. Pinus stand has the most various medicinal plants due to its large size 110,5 ha. Sustainable Management Model of GWEF offered in the thesis is how to utilized medicinal plants in this area so that GWEF can increase their income and support their daily management, and how to involve surrounding community so they can gain benefit from the forest. There are 3 suggested activities for the model: (1) cultivation of medicinal plants, (2) introduction of medicinal plant’s home industry, and (3) promotion of eco-tourism. Location for cultivation of medicinal plants are (1) in bare-land area of GWEF, about 22 ha, for cultivation of Zingiber officinale Roxb., Curcuma domestica Val., Alpina galangal (L). Swartz, and collection of Imperata cylindrical Ness.; and (2) in agroforestry area, about 100 ha, for amomum cardamomum L., Centella asiatica (L) Urb., Piper betle L., piper ningrum L., and Piper retrofractum Val. These species are chosen based on their ecological relation to GWEF, their medicinal values, needed by Indonesia Traditional Medicine Industries, and familiar to surrounding communities. Eco-tourism is the most suggested activity in GWEF for its landscape, history and functions. Medicinal plant knowledge and home industry wrapped in eco-tourism will become aa interesting package of eco-tourism program in GWEF. Eco-tourism is a type of mechanisms of rewards for environmental services provided by surrounding communities. In eco-tourism program, the agroforestry farmers who cultitave various species of medicinal and agricultural plants are identified as one of environmental service (ES) providers/sellers together with copal collectors, and the rest of surrounding communities. The beneficiaries/buyers of ES are the tourists. The manager of GWEF is the intermediary and with support from NGO and donor bodies, eco-tourism program as mechanism of rewards will benefit surrounding communities, so they will continue providing the ES and at the same time preserving, protecting, and conserving GWEF.

Kuswandono, Arzyana Sunkar, Lilik Budi Prasetyo, Usep Suparman and Adam A. Supriatna
A management approach to conserve the Endangered Javan Hawk-Eagle (Spizaetus bartelsi) which is different from the already existing conservation approach, has been studied. The study had been conducted since December 2009 to February 2010 in Gede-Pangrango National Park, Telaga Warna Nature Reserve, and its surrounding forested areas. All study areas are in West
Java. The objectives of the study are: 1) to identify stakeholders closely related to the Javan Hawk-Eagle conservation efforts, 2) to identify relevant regulation related to the Javan Hawk-Eagle conservation efforts, 3) to understand the stakeholders performance in relation to the Javan Hawk-Eagle conservation efforts, 4) to find out the possible gaps in conservation efforts of the species, and 5) to identify factors causing the gap. Primary data were collected using in-depth interview and field observation while secondary data were collected through study of relevant references. Stakeholders were identified through snowball method. I conducted spatial analysis, stakeholder identification analysis, content analysis, and gap analysis. Results of the study recognized two conservation management approaches: 1) species level and 2) habitat level. These approaches will effectively conserve the existing fragmented and less protected forest blocks as well as boosting the participation and synergism of many stakeholders. Further, by using this approach, a gap in conservation management among local conservation agencies will also be discussed for the benefit of the Javan Hawk-Eagle in particular and for biodiversity in general.

Abstract
Community forest at Kuningan district, West Java province, shown its forest cover improvement at average of 5,86% during 2003-2009. This forest potentially serves as protected area outside state forest in land use plan of Kuningan district. The forestland status is private property whereas for the owner serves as production forest. The aim of this research is to assess performance of that community forest management using set of criteria and indicators for sustainable community-based forest management developed by the Indonesian Ecolabelling Institute/LEI (2002). The result shows that management practiced fail to fulfill the standard. Nevertheless private property rights of forest land status enabled the owner to invest in forest development for economic benefit, which public perceived has provide a positive impact for environmental services. Lack of technical capacity in forest management and institutional management need to be improved to enable the owner gain economic benefit while provide environmental services for public.
