Abstract

Oriental honey buzzards (OHBs, Pernis ptilorhynchus) are one of migratory raptor from Japan to Indonesia which is widely recognized as indicator species reflecting the conditions of their habitat. Since 2003, OHBs have been satellite-tracked in their wintering grounds in Indonesia. Less information available on wintering areas in the west Java, which hampers the OHB conservation efforts. This paper proposes a new approach for predicting the probability models of the wintering habitat distribution of OHBs with the presence data derived from satellite tracking using logistic regression analysis coupled with RAMAS GIS. This spatial model was locally constructed from the data concerning Talaga Bodas and its surrounding areas and extrapolated for the entire West Java region. The best predicted probability model successfully characterized the distribution of the OHB wintering habitat using slope (25–40%), elevation (0–300 m and >1,000 m), and land cover (forest, paddy field, and water body). The extrapolation model generated potential areas of the wintering habitat distribution covering an area of 3013.13 km2 (8.11% of West Java). These areas were predominantly located outside the protected areas (94.04%). The modeling approach proposed herein may be used to study other migratory species that are tracked using satellite or other navigation technologies.

Abstract

ABSTRACTCorridors are narrow strips of land which differ from the matrix on either side. There are two types of corridors, namely linear corridor and stepping stone. One example of corridor is a landscape along the path of KRL Railway Bogor-Jakarta Kota. Corridor is important for bird movement. Nowadays there is habitat fragmentation along the corridor which is threatened their corridor function. Therefore it should be maintained for sustainable corridor. This study was conducted at corridor along the KRL Railway Bogor-Jakarta Kota which is divided into five segment. Three analyses were used in this study, i.e. corridor distribution analysis, vegetation analysis and bird abundance analysis. Stepping stone corridor has higher number of bird abundance than the linear corridor. Both of corridors have the potential to become a habitat of birds which is indicated by abundance species of birds. The highest abundance of a bird was found in corridor with diversity of plants (Shannon Wienner Index) in the medium level. Several recommendation have provided for managing the corridor such as managing and revitalizing the corridor, increasing vegetation diversity and increasing public awareness for bird habitat conservationKeywords : birds, GIS, habitat fragmentation, linear corridor, stepping stone

Abstract

Green open spaces can be potential habitats for birds in urban landscapes. Due to high number of land development, the green open spaces in urban landscapes tend to be small and scattered. Indeed, analysis about effectivity of green open spaces as bird habitats in Bogor City and its surroundings is needed. We investigated bird habitat patches on 14 locations in Bogor City and its surroundings. This study aimed to analyze the effectiveness of bird habitat patches for bird species richness using two variables (size and complexity). The data were analyzed using the Pearson Correlation and multiple linear regression. The results showed that there were no significant differences between bird species richness and size of patches. Conversely, there were significant differences between bird species richness and complexity of patches. The Pearson Correlation revealed that there were high correlation between bird species richness and complexity of patches. Finally, we propose three recommendations of green open spaces as bird habitat patches in Bogor City and its surroundings, such as protecting and managing both small and large bird habitat patches, increasing number of vegetation strata and number of vegetation in some strata in small bird habitat patches, and increasing number of vegetation in some strata in large bird habitat patch with low bird speciess richness.

Abstract

Urban forests have benefits for urban recreational activities for dwellers and also the identity of a city. East Jakarta is one of the areas in DKI Jakarta that has the largest number of urban forests currently. Urban forest has not been utilized optimally by the dwellers. For recreation activities, urban forest utilization for recreation activities become an interesting to observe. Therefore, the objective of this study was to analyzed urban forests utilization by the dwellers,especially in East Jakarta. Observation was done through interview and then was analyzed using linier regression. Urban forests coverage area were determined through buffer analysis using the level of urban forest accessibility by walk. The results shown that 85% urban forests was visited by dwellers came from inside urban forest coverage area. Recreational activities recorded while observed in the urban forest were exercising, sightseeing, picnic, camping, etc. The number of object in each urban forest was positively correlated with the high proportion of visitor from outside the urban forest coverage area.

Abstract

Birds of prey are one of environmental changes indicators because of their position as top predator. Many of them are migratory species that migrate from northern hemisphere to southern hemisphere, and use Rupat Island (in Riau Province) as stopover habitat. One of them is Oriental Honey Buzzard (Pernis ptilorhynchus) whose satellite tracking information (from 2006-2009) are available. This study aimed at identifying distribution characteristics of stopover habitats of Oriental Honey-buzzard in Rupat Island based on satellite tracking data using geographic information system (GIS). Several environmental variables (i.e. slope, elevation, land cover) were processed into distance to the nearest map and analyzed using logistic regression analysis. The result showed that distribution of stopover habitats covered 1 276.67 km2 (87%) of totally Rupat Island (1 461.95 km2). This distribution was mostly influenced by food availability and thermal wind. Identification of these habitat characteristics provides a baseline data for managing their stopover habitats and ecologically-based development of Rupat Island. Keywords: Logistic Regretion, Pernis ptilorhynchus, Rupat Island, Sattelite-tracking, Stopover habitat characteristic

Abstract

Javan Hawk-Eagle (JHE, Nisaetus bartelsi) which is endemic raptor in the natural forests of Java, Indonesia is categorized as one of the endangered. Small population size, severe habitat loss, forest fragmentation, and illegal hunting have contributed to the ‘‘endangered’’ status of this species. Moreover, conservation of this species has become a national priority. This study was being conducted because of the lack of information about the distribution of JHE’s remnants habitat which caused the proposed conservation strategies for JHE become difficult. This study aimed for updating data of JHE’s remnants habitat in West Java, analyzed its habitat patches distribution, and estimated the number of its populations. The previous study determined the habitat suitability probability modelling of JHE with used landsat images in 2002 at southern part of West Java. This study updated the model using the same logistic regression model equation in West Java overall. This study identified 17 remnant habitat patches (3 955 km2) scattered in West Java. The comparison with previous study showed that the size and number of patches was increased with the predicted number of JHE’s populations were about 39-195 (median = 117) pairs in southern part of West Java. Based on the results, we offer three recommendations to increase the survival of JHE’s habitat in West Java.Keywords: GIS, habitat remnants, logistic regression, Nisaetus bartelsi, patch.

Abstract

Increasing of economic development is generally followed by the change of landuse from agriculture to other function. If it occurs in large frequency and amount, it will threaten national food security. Therefore, it is necessary to monitor the agricultural land, especially paddy fields regarding to changes in landuse and global climate. Utilization and development of satellite technology is necessary to provide more accurate and independent database for agricultural land monitoring, especially paddy fields. This study aims to develop a utilization model for LAPAN-IPB satellite (LISAT) and other several satellites data that have been used for paddy field monitoring. This research is conducted through 2 stages: 1) Characterization LISAT satellite data to know spectral variation of paddy field, and 2) Development method of LISAT data fusion with other satellites for paddy field mapping. Based on the research results, the characteristics Red and NIR band in LISAT data imagery have a good correlation with Red and NIR band in LANDSAT 8 OLI data imagery, especially to detect paddy field in the vegetative phase, compared to other bands. Observation and measurement of spectral values using spectroradiometer need to be conducted periodically (starting from first planting season) to know the dynamics of the change related to the growth phase of paddy in paddy field. Pre-processing of image data needs to be conducted to obtain better LISAT data characterization results. Furthermore, it is necessary to develop appropriate algorithms or methods for geometric correction as well as atmospheric correction of LISAT data.

Abstract

Environmental damage due to tin mining in Bangka Regency, especially in Merawang District is increasing. The negative impacts of this mining are eliminating the composition or structure of vegetation, changing the function of wildlife habitat, changing the shape of the landscape, producing waste, and draining ground and surface water. One form that can be developed in the development of post-tin mining areas that are environmentally friendly is the development of tourism based on local wisdom while still paying attention to natural resources, especially conservation areas such as protected forests and borders. Tourism development is carried out to restore the area with various activities that involve the community. The results of spatial analysis of tourism suitability in Merawang District have very suitable criteria (S1) with tourism suitability index (IKW) of 67.29% and suitability (S2) with IKW value of 19.82% and not suitable (S4) with IKW value of 12, 89%. Local wisdom in Merawang District is based on AHP analysis in the ecological aspects of "customary forests", social aspects of "nganggung", economic aspects of "typical culinary", and historical aspects of "becampak". Meanwhile, the most priority local wisdom based on all aspects is obtained "typical culinary".

Abstract

Raptor migration is complex phenomenon of migration which involving of millions of individual birds flying hundreds or thousands kilometers, between breeding habitat and wintering habitat. Migratory behavior consisted of period, route, and other aspects that affect the ecology of migratory birds. Pernis ptylorhynchus, Oriental honey-buzzard (OHB) is one of migratory raptors which have satellite tracked by ARGOS since 2003. Eastern part of Flores Islands consisted of small islands (23 islands) were identified as OHB’s migratory path to reach their wintering habitats in Kupang and Timor Island. This study has aimed to identify and analyze the OHB’s migratory behavior in Eastern part of Flores Islands. Four individuals OHB have satellite tracked in the period of 2007-2012 were used as main data for analyzing their migratory behavior. There was no particular pattern found on the way of OHBs selected islands for their stopover site because of the existence of small islands cluster provide variety of route for each OHBs. The length of their stay found relatively constant every year and tend to be stay longer on larger islands than the smaller one such as Flores Island and Lembata Island. This is apparently due to the larger islands provide more food supply than smaller islands.
