The existence of vegetation as a provider of ecological services in the form of carbon dioxide (CO2) absorption and carbon storage certainly has a very important role, either in living conditions (biomass) or dead conditions (necromass). The aims of this study are to determine the total amount of above-ground carbon stock and determine the type of land-use that has the greatest carbon storage potential in the Kamojang region. Data collection in this research combines destructive and non-destructive methods. The measurement of biomass was carried out by the non-destructive sampling method for the category of sapling, poles, trees and necromass and the destructive sampling method for the category of undergrowth and litter. The results showed total above-ground carbon stored in Kamojang area is 4,995.75 t C with the largest potential value of carbon stock in the pine production forest of 163.79 t C/ha.

This study was carried during the periods of September/October/November (36 days) in 1997 and of August/September (25 days) in 1998. We recorded the tree names foraged on, foraging duration, DBH and the number of cofeeders in a feeding bout in a tree, in order to evaluate food preferences, i.e., (total consumption by cofeeders in a bout)/(estimate of leaf biomass). The rank order of the preferences in each species indicates the lutong mainly foraged on some secondary succession tree species and artificially introduced species. Most preferential items were buds and shoots of the introduced species, e.g., mahogany and Dalbergia, of maritime cosmopolitan tree species, and of fig trees in both 1997 and 1998. Severity is in the 1997's, but the lutong mainly foraged on mahogany, which put forth bud in spite of the drought. One of the possible reasons is that constant high density of the lutong population may have the key resources that exist in the ecosystem during the periods against survival pressure.

Indonesia as a developing country has committed to reducing greenhouse gas (GHG) emissions by 29 percent by the year 2030. This calls into question the extent of how the cities or local governments can cope with the challenges of the current transport sector climate change mitigation in Bandung City. This paper aims to assess the governance context of climate policies in Bandung City and support further co-benefits. The preliminary stage of study shows that the policies in reducing GHG emissions are not in accordance with what was written by the government. The provincial and local government was aware that the stipulation delivered by the central government regarding mitigation on climate change stated in the regulation both in provincial and local level. Based on the actor"s characteristic, the policies that encourage to reduce GHG emissions drive as a multi-actor interaction process namely The Paratransit, Trans Metro Bandung (TMB) and Vehicle Emissions Test. The research design involved an empirical case study on governance and policy relevant to climate change efforts to lower GHG in Bandung City, Indonesia. The analytical framework used for this analysis is the Governance Assessment Tool and the co-benefits approach. Data collection involved semi-structured interviews, a review of policy documents, and secondary quantitative data. The results reveal that the governance qualities create a context that there still are some limits, although several improvements have shown the positive trend at the local level. This is due to the qualities of the extent aspect as a low to moderate, the flexibility as a restrictive, and the coherence and intensity as moderate. The assessment of the criteria of co-benefits is more relevant to the public transport. The TMB has met all of the criteria of co-benefits. Thus, this TMB program has the highest impact to attain the co-benefits. The paratransit has the positive value of the criteria for lowering GHG emissions, energy and environmental sustainability, and development goals. The vehicle emission test met the criteria of sustainability and technical feasibility.

Nowadays, however, the huma farming has rarely been practiced by the village people of West Java due to the government policy, and environmental and socioeconomic changes. The local community who reside in the Villages of Bojongsalam and Sukaresmi, the upper stream of Cisokan, West Java, Indonesia, has still practiced both the wet rice field (sawah) and the huma farming in the private land, production forest of a state-owned forest company (Perhutani), and a state-owned electric company (PLN) project land. Recently some areas of the huma land have been used for the project of the Hydroelectric Power Plant of the Upper Cisokan Pumped Storage (UCPS). As a result, the sustainability of huma system of the local people of Bojongsalam and Sukaresmi has been seriously disturbed. The aims of this study were to elucidate the local management of the huma farming systems that are undertaken by local people of Bojongsalam and Sukaresmi Villages, and to analyze the sustainability of the huma farming of local people of Bojongsalam and Sukaresmi Villages as affected by the UCPS Hydroelectric Power Plant project. The qualitative method was used, while several techniques of collecting the primary data, namely observation and in-depth interviews with informants were applied in this study. The results of study showed that the local management of the huma farming has been annually undertaken by the local people of Bojongsalam and Sukaresmi, including deciding the location of huma plot, preparing the land (cutting shrubs and burning vegetation biomass), planting rice (ngaseuk) and other annual crops, weeding (ngored) and providing chemical fertilizers (mupuk), controlling pests, harvesting rice (dibuat), and fallowing land. Based on analysis of the emergent properties of the agroecosystem of huma farming, it can be predicted that productivity, stability, equitability, and sustainability of the huma farming systems of Bojongsalam and Sukaresmi Villages tend to be low in the near future due to the impact of UCPS Hydroelectric Power Plant project.

One of these studies was the UCPS Biodiversity Management Plan (BMP). The aim of this study was to identify the strategy for biodiversity management at the project site. Methods of this study were based on several years of qualitative and descriptive-analytical studies, which updated information from earlier studies. Information on the area's biodiversity was obtained directly through field surveys and indirectly through semi-structured interviews and focus group discussions (FGD) with local community members and other stakeholders in the area. This article presents the strategy for biodiversity management at project site, including minimizing habitat gap and habitat loss; expanding and enriching habitats; making corridors; protecting the natural forests (protection of remnant forest); controlling access; managing fire, the impact of traffic on native fauna, land clearing and human-wildlife conflict; minimizing impacts to biodiversity, particularly threatened species; integrating management with adjoining land managers (PLN, perhutani, the community); strengthening capacities for integrating and institutionalizing biodiversity conservation and management; conducting campaign for biodiversity awareness, communication, and education; and developing value-added products and alternative sustainable livelihood for bio-resource-dependent communities.

Nonetheless, there is little information about their responses to infrastructure development impacts the habitat preference of leopard cats. This study aims to reveal the habitat preferences of leopard cats in the Upper Cisokan Pumped Storage (UCPS) hydropower development area, Cianjur Regency and West Bandung Regency, West Java. Direct observation was conducted to collect habitat preference in terms of biotic, abiotic and anthropogenic parameters and analyzed using Vanderploeg and Scavia's Resource Selection Index (VSI). The results showed that in term of biotic factors, leopard cats preferred natural forests, shrubs, and rice fields; tree canopy area of 51%-75%, tree DBH >20 cm, tree height 0-5 m and 11-15 m, and tree density of 0-20 trees. Leopard cats preferred 76%-100% shrubs canopy; ground-plant cover of 26%-75% with withered grass cover of 76%-100%. According to their abiotic factors, leopard cats preferred habitats with north and south, gentle, and lower slopes. The leopard cats also preferred habitat with wet soil. In term of anthropogenic factors, leopard cats preferred habitat close to water sources (<500 m). Leopard cats chose habitats with moderate distances (500 m-1000 m) from anthropogenic disturbances with weak intensity. Agricultural activities could affect its habitat preference directly. Leopard cats were found at various levels of disturbance in humanmodified lands, such as rice fields and shrublands. Since the main prey is cosmopolitan animals, as long as there is human-modified land, prey availability will remain guaranteed. Although the leopard cat can tolerate anthropogenic disturbances, there is little information on the direct impact of construction activities on this population, so further research is needed to observe their population and habitat in the construction area.

Herpetofauna can experience environmental stress due to agricultural activities, tourism, and other disturbances that result in habitat loss. Herpetofauna can be found on various land covers, such as natural forests and human-modified land. This study revealed species associated with natural forests, human-modified land, and both. This study aims to investigate: 1) herpetofauna distribution based on land cover types and 2) the disturbance that threatens the herpetofauna habitat in West Java. Visual Encounter Survey combination with the Auditory Encounter Survey, was applied in this study. The result of this study, the species were found in the natural forest (53 species), human-modified land (63 species), and crater (2 species). Thirty-nine species were found both in the natural forest and human-modified land. The habitat disturbance potentially threatens the species, such as land clearing (it will affect the microclimate of land cover), roadkill, infrastructure development, and tourism activities.

Besides, many built-up areas due to the urbanization in peri-urban areas also impact habitat quality, such as the loss of plants commonly used as perching and nesting sites. Along with the development of Rancabayawak as a built-up area, it is essential to study the management of those birds. This study aims to reveal: 1) plants used as perching and nesting sites, 2) population size and distribution, and management efforts on B. ibis, E. garzetta, and A. speciosa in Babakan Rancabayawak Hamlet, Gedebage Subdistrict, Bandung, West Java, Indonesia. A mixed-methods approach was applied in this study by calculating the estimated population and bird nests, plant inventory survey, and the installation of the A8 mini GPS. Bambusa vulgaris, Leucaena leucocephala, and Mimosa pigra are plants that are used as perching and nesting sites by B. ibis, E. garzetta, and A. speciosa. The estimated population mean of those birds was 630 individuals, 92 individuals, and 43 individuals, respectively, with the population average of those birds, is 1680 individuals. Three hundred twenty-nine nests (329) were found during the study. Based on distribution mapping, birds moved east and south, covering paddy fields in Rancaekek, Solokanjeruk, and Majalaya within a radius of 12 km. Management efforts can be conducted by not cutting down the plants that become nesting and perching sites and maintaining the wetlands in their habitats.

This study aimed to investigate the diversity of birds (avifauna) in three geothermal power plant areas in West Jawa Province, Indonesia (i.e., Kamojang, Darajat, and Gunung Salak). Transect and spotlighting methods were conducted in this study. We found that areas around geothermal power plant in Gunung Salak had the highest diversity of bird species with 105 species from 43 families, followed by Kamojang with 82 species from 34 families, and Darajat with 80 species from 40 families. In total, there were 134 species from 51 families in which two species are Endangered (EN) under the IUCN Red List category, five are endemic to Java, 11 are protected by CITES Appendix II and 14 are protected by national regulations. The presence of some birds was an indicator of ecosystem condition and functioning, including indicator of food chain, quality of water, quality of natural habitat, condition of riparian habitat, and the condition of open or disturbed habitat. Some birds were also associated with particular habitats, such as natural forests, riparians, a combination of natural forests and open habitats, tea plantations, and craters. The results of this study can be used as baseline information about the state of the surrounding environment in the three geothermal power plant areas and as a reference in biodiversity management in the future.

Ecovillage is a concept where the community have to manage the environment properly and all the activities have a positive impact on the environment. In practice, the ecovillage should follow four aspects as follow: Ecology, Economy, Social and Spiritual aspect, on which of each this aspect are evaluated and analyzed. This research is different from the existing research because it will assess four sustainability aspects of the ecovillage. This research focused its research on the West Java Environmental Agency's Ecovillage program in Bendungan Village,

Nowadays, however, the huma farming has rarely been practiced by the village people of West Java due to the government policy, and environmental and socioeconomic changes. The local community who reside in the Villages of Bojongsalam and Sukaresmi, the upper stream of Cisokan, West Java, Indonesia, has still practiced both the wet rice field (sawah) and the huma farming in the private land, production forest of a state-owned forest company (Perhutani), and a state-owned electric company (PLN) project land. Recently some areas of the huma land have been used for the project of the Hydroelectric Power Plant of the Upper Cisokan Pumped Storage (UCPS). As a result, the sustainability of huma system of the local people of Bojongsalam and Sukaresmi has been seriously disturbed. The aims of this study were to elucidate the local management of the huma farming systems that are undertaken by local people of Bojongsalam and Sukaresmi Villages, and to analyze the sustainability of the huma farming of local people of Bojongsalam and Sukaresmi Villages as affected by the UCPS Hydroelectric Power Plant project. The qualitative method was used, while several techniques of collecting the primary data, namely observation and in-depth interviews with informants were applied in this study. The results of study showed that the local management of the huma farming has been annually undertaken by the local people of Bojongsalam and Sukaresmi, including deciding the location of huma plot, preparing the land (cutting shrubs and burning vegetation biomass), planting rice (ngaseuk) and other annual crops, weeding (ngored) and providing chemical fertilizers (mupuk), controlling pests, harvesting rice (dibuat), and fallowing land. Based on analysis of the emergent properties of the agroecosystem of huma farming, it can be predicted that productivity, stability, equitability, and sustainability of the huma farming systems of Bojongsalam and Sukaresmi Villages tend to be low in the near future due to the impact of UCPS Hydroelectric Power Plant project.

One of these studies was the UCPS Biodiversity Management Plan (BMP). The aim of this study was to identify the strategy for biodiversity management at the project site. Methods of this study were based on several years of qualitative and descriptive-analytical studies, which updated information from earlier studies. Information on the area's biodiversity was obtained directly through field surveys and indirectly through semi-structured interviews and focus group discussions (FGD) with local community members and other stakeholders in the area. This article presents the strategy for biodiversity management at project site, including minimizing habitat gap and habitat loss; expanding and enriching habitats; making corridors; protecting the natural forests (protection of remnant forest); controlling access; managing fire, the impact of traffic on native fauna, land clearing and human-wildlife conflict; minimizing impacts to biodiversity, particularly threatened species; integrating management with adjoining land managers (PLN, perhutani, the community); strengthening capacities for integrating and institutionalizing biodiversity conservation and management; conducting campaign for biodiversity awareness, communication, and education; and developing value-added products and alternative sustainable livelihood for bio-resource-dependent communities.

Nonetheless, there is little information about their responses to infrastructure development impacts the habitat preference of leopard cats. This study aims to reveal the habitat preferences of leopard cats in the Upper Cisokan Pumped Storage (UCPS) hydropower development area, Cianjur Regency and West Bandung Regency, West Java. Direct observation was conducted to collect habitat preference in terms of biotic, abiotic and anthropogenic parameters and analyzed using Vanderploeg and Scavia's Resource Selection Index (VSI). The results showed that in term of biotic factors, leopard cats preferred natural forests, shrubs, and rice fields; tree canopy area of 51%-75%, tree DBH >20 cm, tree height 0-5 m and 11-15 m, and tree density of 0-20 trees. Leopard cats preferred 76%-100% shrubs canopy; ground-plant cover of 26%-75% with withered grass cover of 76%-100%. According to their abiotic factors, leopard cats preferred habitats with north and south, gentle, and lower slopes. The leopard cats also preferred habitat with wet soil. In term of anthropogenic factors, leopard cats preferred habitat close to water sources (<500 m). Leopard cats chose habitats with moderate distances (500 m-1000 m) from anthropogenic disturbances with weak intensity. Agricultural activities could affect its habitat preference directly. Leopard cats were found at various levels of disturbance in humanmodified lands, such as rice fields and shrublands. Since the main prey is cosmopolitan animals, as long as there is human-modified land, prey availability will remain guaranteed. Although the leopard cat can tolerate anthropogenic disturbances, there is little information on the direct impact of construction activities on this population, so further research is needed to observe their population and habitat in the construction area.

Herpetofauna can experience environmental stress due to agricultural activities, tourism, and other disturbances that result in habitat loss. Herpetofauna can be found on various land covers, such as natural forests and human-modified land. This study revealed species associated with natural forests, human-modified land, and both. This study aims to investigate: 1) herpetofauna distribution based on land cover types and 2) the disturbance that threatens the herpetofauna habitat in West Java. Visual Encounter Survey combination with the Auditory Encounter Survey, was applied in this study. The result of this study, the species were found in the natural forest (53 species), human-modified land (63 species), and crater (2 species). Thirty-nine species were found both in the natural forest and human-modified land. The habitat disturbance potentially threatens the species, such as land clearing (it will affect the microclimate of land cover), roadkill, infrastructure development, and tourism activities.

Besides, many built-up areas due to the urbanization in peri-urban areas also impact habitat quality, such as the loss of plants commonly used as perching and nesting sites. Along with the development of Rancabayawak as a built-up area, it is essential to study the management of those birds. This study aims to reveal: 1) plants used as perching and nesting sites, 2) population size and distribution, and management efforts on B. ibis, E. garzetta, and A. speciosa in Babakan Rancabayawak Hamlet, Gedebage Subdistrict, Bandung, West Java, Indonesia. A mixed-methods approach was applied in this study by calculating the estimated population and bird nests, plant inventory survey, and the installation of the A8 mini GPS. Bambusa vulgaris, Leucaena leucocephala, and Mimosa pigra are plants that are used as perching and nesting sites by B. ibis, E. garzetta, and A. speciosa. The estimated population mean of those birds was 630 individuals, 92 individuals, and 43 individuals, respectively, with the population average of those birds, is 1680 individuals. Three hundred twenty-nine nests (329) were found during the study. Based on distribution mapping, birds moved east and south, covering paddy fields in Rancaekek, Solokanjeruk, and Majalaya within a radius of 12 km. Management efforts can be conducted by not cutting down the plants that become nesting and perching sites and maintaining the wetlands in their habitats.

This study aimed to investigate the diversity of birds (avifauna) in three geothermal power plant areas in West Jawa Province, Indonesia (i.e., Kamojang, Darajat, and Gunung Salak). Transect and spotlighting methods were conducted in this study. We found that areas around geothermal power plant in Gunung Salak had the highest diversity of bird species with 105 species from 43 families, followed by Kamojang with 82 species from 34 families, and Darajat with 80 species from 40 families. In total, there were 134 species from 51 families in which two species are Endangered (EN) under the IUCN Red List category, five are endemic to Java, 11 are protected by CITES Appendix II and 14 are protected by national regulations. The presence of some birds was an indicator of ecosystem condition and functioning, including indicator of food chain, quality of water, quality of natural habitat, condition of riparian habitat, and the condition of open or disturbed habitat. Some birds were also associated with particular habitats, such as natural forests, riparians, a combination of natural forests and open habitats, tea plantations, and craters. The results of this study can be used as baseline information about the state of the surrounding environment in the three geothermal power plant areas and as a reference in biodiversity management in the future.
