The Dynamic of Functional Microbes Community Under Auri (Acacia auriculiformis Cunn. Ex Benth) Agroforestry System
Get PDFMicrobes are important rhizosphere constituents for providing nutrients in the soil. This study analyzes the dynamic of soil functional microbes’ populations on land managed as an agroforestry (AF) system. The AF system consists of a 2-years old auri tree combined with several crops, i.e., wild grasses, peanuts (Arachis hypogaea), pigeon pea (Cajanus cajan), and maize (Zea mays). Soil samples were collected from each rhizosphere and then analyzed for their chemical properties such as N, P, K, pH, and C organic contents. The population of functional microbes was observed by isolation of the non-symbiotic N-fixer microbes (BNF), the cellulose-degrading microbes (CDM), and the phosphate solubilizing microbes (PSM) in their selective media. The total soil sugars were also tested for root exudates. The results showed that in an auri agroforestry system, the kind of crops determines the content of the soil organic material that is turned-offer into the soil. This affects the population structure and functional microbial abundance in the rhizosphere. Furthermore, microbial colonization in the rhizosphere affects plants in producing root exudates. Then, root exudates shape the structures of the microbial community, as well as an influence among inhabitants in defining mineralization of soil organic matter, nutrient availability, and trees performance.
 
Polarization among Stakeholders Perception on the Interpretation of Ecotourism Resources in Gunung Halimun Salak National Park
Get PDFThe study of polarization of stakeholder perceptions is important to consider the policies that must be taken by area managers related to the development of interpretation programs in national park areas. This study was aimed to analyze and evaluate the characteristics of the subject of interpretation that are considered important by stakeholders, to analyze the differences in perceptions among stakeholders of the attractiveness of the subject of interpretation and to determine the polarization of perceptions of the subject of interpretation among stakeholders in relation to the management of Gunung Halimun Salak National Park (GHSNP). Stakeholder perception data was obtained by distributing a closed pattern questionnaire. Cluster analysis was used to determine the variety of stakeholder perception in interpretation subjects within the GHSNP area. As for knowing the direction and scale of the polarization of stakeholder perceptions, it was analyzed by Kruskal Wallis and Mann Whitney test. The results showed that the largest polarization among stakeholders occurred in the cultural subjects, and the direction of polarization was negative. This indicates the weak attractiveness of the subject of cultural interpretation to stakeholders. The greater commonality of perception between the community and managers forms the basis for the development of cultural interpretations. This development is expected to bridge the community\u27s needs for the GHSNP area as well as provide stronger support for the management of the national park area.
 
Ecotourism of Cireundeu and Basic Sundanese’ Way of Life
Get PDFNowadays, some indigenous religion members in Indonesia are still fighting to grasp a fully civil rights recognition granted by the state. However, the way of such effort undertaken by people of Sunda Wiwitan of Cireundeu Cimahi is different. Rather than claiming the civil rights rigorously, they introduce as well as organize community ecotourism by preserving natural environment combined with Sundanese culture. This article aims at uncovering social changing around the shifting point of organizing ecotourism, objections from outsiders and adaptation with social environment whereby they negotiate with. Based on qualitative research which focuses on observation, in-depth interview, as well as literature study, this paper aims to portray the ecotourism initiative and its recent empowerment in this community which currently makes their customary village (kampung adat) well-known as one of the Sundanese cultural tourism destinations for not only Bandung greater area people, but also for the people of outside Bandung and abroad as well. The result shows that albeit some restrictions on expressing civil rights status still occur, having previous experience of losing informal job and objections from other groups alike, this community can maximize their teaching as well as their natural landscape potential in managing self-ecotourism based on their local cultural values.
 
How do the Customary Forest and Protected Forest Management Principles affect Ambon City Protected Forest Management between the Government and Indigenous Peoples? (Case in the Mount Sirimau Protection Forest Group, Ambon City, Maluku Province)
Get PDFProtection forests are state forests that are authorized by the government to be managed, but on the other hand, indigenous peoples already exist and manage forests that are claimed as customary forest. How is the management of protection forests between the government and indigenous peoples? The purpose of this study is to examine the management of protection forests between the government and indigenous peoples and the collaboration in the management of protection forests between the two. The results showed that the management of protection forests by the government was not optimal at the site level based on the principles of protection forest management that had only been done with boundaries: only area boundaries, not blocks and plots, forest protection such as area patrols, installation of prohibition boards and appeals) and land rehabilitation (planting with woody plant species and multi-purpose trees. Protected forest management by indigenous peoples has touched the site level on several aspects of protected forest management principles. Protected management activities by indigenous peoples following the principles of protected forest management are the cultivation of fruit plants, land use with dusung/traditional agroforestry cropping patterns, forest protection is prohibited from cutting trees at water sources, along riverbanks, replanting if cutting fruit trees that are not productive, utilizing non-timber forest products. The government as the planner but implementing it in the field is the indigenous people who are accompanied by the government and joint monitoring and evaluation. Protected forest management based on the principle of protected forest management is more optimally carried out in a collaborative and complementary manner between the government and indigenous peoples
Contribution the Failure Mode Analysis and Criticality Evaluation Method to the Rehabilitation of Cork Oak (Quercus suber) Forests in Forest Massif of Tlemcen (Algeria)
Get PDFThe controling of forest sustainability and preforest ecosystems in achieving stability of forest ecosystem require the identification of biophysical indicators, anthropological, and technological. The significant degradation of Quercus suber formations in forest massif of Tlemcen (Algeria) are imposed by both climatic factors, the fires, the overgrazing land, anthropogenic aggression as well as by ineffective management. The making of a reference matrix would make possibility the identification of probable hazards and risks. This study aimed to identify the understanding how the mode of operation of a system to identify failures and treat, and the create the intention of eliminating or minimizing the associated risks. This matrix will consist of relevant indicators which easy guide to estimate and following the understanding of the forest degradation process in Algeria. The FMECA method allowed identification of 20 main defective targets which be grouped into 3 categories namely: technical, ecological, organizational, and facilitate of remediation. Each error can be scored and action plans can be prioritized, allowing different with all forest sector players to better understand the degradation of this natural space in order to implement efficient and appropriate remediation plans.
 
A Model of Religious Moral Approach for Peatland Ecosystem Restoration in Indonesia
Get PDFEfforts to conserve peatlands and prevent forest fires are inseparable from human awareness and behavior. This study aims to find a model for a religious, moral approach by the clerics in supporting the implementation of peatland restoration. The study was carried out in designated Muslim locations with trained clerics. The farmers surveyed also have experienced by the Peatland Restoration Agency (BRG) programs: i.e., physical support, such as a canal dam program and demonstration plot of agriculture without burning (PLTB). The methods used combine quantitative surveys with a Likert scale to explore attitudes, subjective norms, perception, intention, and their impact on behavior. The results obtained show that the community religious leaders can be an important trigger in encouraging the movement. In the model, visible subjective norm (SN) variables contribute directly to intention by 23%. Perceived behavior control (PBC) directly has a positive and significant effect on intention 53% (p-value). This means the individual, in making a decision and intention to participate, is a factor that has a broad impact on the community and gives a positive value of 53% (good enough) on the intention. The individuals\u27 decisions to participate in peatland conservation are prompted by perception of having a wide impact on the community
