Strategi Pengembangan Ekowisata di Kabupaten Kepulauan Yapen Provinsi Papua
Get PDFYapen Islands Regency has a very potential and feasible capital to be developed as a tourism attraction object. However, its ecotourism management does not optimal because of several constraints such as lacking institutional capacity of ecotourism management, weak attraction management, less spatial planning of tourism, and ineffective promotion and marketing, as well as problems on regional security. This research was conducted to formulate strategies to develop the islands ecotourism. The results showed that most of the tourism attractions (sea, water, and land ecotourism objects) in Yapen were feasible for further development ecotourism attractions. However, some of the potential tourism objects were not yet possible to be developed due to some barriers and constraints, i.e. unsupportive market potential, bad access due to location of the objects, below-standard management and services, poor accommodation, and high similarity with other objects. The research, therefore, recommends that pessimistic strategy should be applied in overcoming the problems. The strategy should be supported by arrangement of the tourism space, development of attractions management, development of promotion and marketing, development of regulations and management in ecotourism organization, and creation of a conducive and secure situation, both within and outside the tourism area
Status and Potential of the Peroryctidae Family to Improve Food Security in Papua New Guinea
Get PDFAs the importance and threats of wildlife resources in Melanesia are widely recognized, their appropriate use is critical to achieve sustainable development in the country. An underestimated relationship between the status of the species with forest condition and food security is discussed. Being as nutritious as conventional imported red meats, bandicoots are also considered as the most rapidly breeding marsupial. The taxonomy, morphology, habitat, and reproductive characteristics of the family Peroryctidae (bandicoots) are succinctly described in order to elucidate the species potential in continuous controlled harvests in the wild and its eventual farming, until now successful abroad with one species from a related family. This effort requires the application of proper regulations that guarantee continuous harvests in accordance to the population dynamics
Effect of Charcoal Earth Kilns Construction and Firing on Soil Chemical Characteristics
Get PDFAssessments of localized ecological and environmental impacts of charcoal production including effects on soils at kiln sites is seldom undertaken, with more emphasis being placed on the global effects of the practice such as forest degradation and deforestation. A study was undertaken in Narok, Eldoret, Moiben, and Turbo in Kenya on known charcoaling sites to investigate the impact of charcoal production on the soil chemical characteristics. Composite soil samples from 12 sampling points for all study sites were taken randomly at a depth of 0–15 cm. The samples were conditioned and analyzed for pH, particle size, Cation Exchange Capacity (CEC), extractable phosphorus, organic carbon, nitrogen, and exchangeable bases. A comparison of the soil properties between undisturbed sites and charcoaling sites showed significant differences for all chemical properties except CEC, Mg, and K. For the Moiben site, only the pH showed no significant difference (p < 0.05). The observed high carbon content reduced with time for the one year following charcoaling activity and was attributed to soil erosion since charcoal production activities reduced the sites vegetation cover. Most chemical changes positively enhanced the nutrients content and availability, but were short lived probably due to soil erosion. These results demonstrate the need to adopt technologies with minimum impact on the soil, or a shift to centralized production sites outside forest ecosystems or farmlands.
Analisis Pemangku Kepentingan dalam Upaya Pemulihan Ekosistem Daerah Tangkapan Air Danau Toba (Stakeholder Analysis on Ecosystem Restoration of Lake Toba Catchment Area)
Get PDFIncreasing population and exploitation of Toba Lake catchment area had caused environmental degradation. Various institutions attempt to rehabilitate the area, including Ministry of Forestry through the ITTO project. The project aims to gather all stakeholders of restoration of Toba Lake catchment area ecosystem and facilitate them to exchange knowledge and information, so that they could have same understanding and build a network. This study was conducted in 3 districts, i.e. Samosir, Simalungun, and Karo. The respondents were selected using snowball sampling. The data was analyzed using stakeholder mapping. The study shows that key stakeholders of Lake Toba catchment area ecosystem restoration are government institutions which their role and functions are still limited according their main tasks which hindered synergic activities among them. There are potential conflict and collaboration among stakeholders which should be managed for the benefit of the project.
Model Penduga Produksi Kopal
Get PDFThe objective of this study was to find out the prediction model for copal production (Y) by the use of prediction variables. The variables were diameter (X1), bark thicknesses (X2), stand density (X3), slope (X4), and direction of the slope (X5). The study was conducted at Senduro Forest District, Probolinggo Forest Management Unit of Perum Perhutani, Unit II East Java. Data was collected from 80 sample trees of Agathis loranthifolia Salibs which were tapped on August 2006. The result of the study showed that there were several regression prediction models for copal production: doubled linear, multiplicative, exponential and quadratic regression models. Multiplicative regression model with the highest R2-adj value was then chosen as the best prediction model for copal production. Thereby, production estimation model of copal production of Agathis loranthifolia Salis. was LogY = 0.397 + 1.54 LogX1 + 0.496 LogX2 - 0.528 LogX3 + 0.201 LogX4 ; or Y = 2.4945X11.54X20.496X3-0.528X40.201; R-Sq =84.7%, R-Sq(Adj) = 83.7%. Keywords: multiplicative regression model, copal, diameter, bark thickness, stand density, slop

Nilai Ekonomi Air Domestik dan Irigasi Pertanian: Studi Kasus di Desa-Desa Sekitar Kawasan Taman Nasional Gunung Halimun
Get PDFThe hydrological function of Gunung Halimun National Park (GHNP) has enormous benefit for local people. To predict the monetary benefit of water stemming from the park, the research was conducted by taking 13 representative samples of villages surrounding GHNP. Through the economic valuation, this research found out that the total economic value (TEV) water was Rp 6.64 billion per year, consisting of water value for domestic uses (Rp 5.22 billion), and water value for agriculture uses (Rp 1.42 billion). The TEV of the water equal to Rp 6.64 billion (Rp 173.278,47 per ha) is representing economic benefit value of water stemming from area TNGH for the community of 51 villages which abut on direct by TNGH. The monetary value certainly will be bigger if we look at the area broader as the all area of watershed function. The enormous benefit value of water (domestic and the agriculture) prove that development of conservation area (in this case is GHNP) do not oppose against economic development
