Abstract

The effect of residential atmosphere environment generally gives environment stress to the life of the dwellers. One of the environment stress source is the unfulfilment of thermal comfort. The rapid development of residential at Denpasar City cause the variation on building density that are low, medium, high, and very high density classifications. Residential configuration of each classification gives very strong influence to status of urban’s thermal comfort. Purpose of the research is to understand the thermal index profile PET, to identify the status of thermal comfort and to analyze the influence of Tmrt to thermal index PET of residential atmosphere environment at West Denpasar Sub-district area. The research was performed at residential atmosphere environment of West Denpasar Sub-district area by using RayMan model simulation to obtain thermal index profile PET. Sampling technique used the stratified random sampling method with data diversity that is used based on the buildings density. The thermal index profile PET of residential of low density classification is the lowest thermal index profile PET compared to the other three classifications, which are the medium, high, and very high density. One hundred percent of status of thermal comfort of residential atmosphere environment is in hot thermal stress and based on average thermal index PET is on physiological stress level of “Strong heat stress”. Tmrt is the most influential variable to thermal index PET. The concept to increase the status of thermal comfort of residential atmosphere environment at West Denpasar area used the bioclimatic approach. Investigation of status of thermal comfort of residential atmosphere environment at West Denpasar Sub-district area has given the directive of urban planning in improving and revitalized urban spaces.

Abstract

Eden 100 Forest Park is an ecotourism area that has the potential of natural resources that can be used as tourist attractions. Forest Park Eden 100 also provides environmental services such as hydrological forest services, forest services as carbon sinks, and forest services in producing timber and non-timber goods. This study aims to find out what environmental services are provided by the Eden 100 forest and to analyze the economic value of environmental services and the obstacles and challenges faced by managers in efforts to preserve forest ecosystems. The results showed that the Eden 100 Forest Park provides environmental services in the form of direct use environmental services, namely wood production with economic value of the economic value of wood production of Rp 7,822,633,800 and non-wood (fruits) of Rp 25,500,000, non-use value directly in the form of natural landscapes (ecotourism) whose value is calculated using the travel cost method (TCM) and a yield of Rp 1,164,181,800 is obtained, non-use value in the form of existence services whose economic value is calculated using the contingent valuation method (CVM) of Rp.60,158,120 , as a carbon sink value which is calculated using the allometric method, and a yield of Rp. 18,161,220,000 is obtained. From the results of this study, it can be concluded that the total economic value of the Eden 100 Forest is Rp. 27,233,693,720. This proves that the existence of the Eden 100 forest is a very big economic benefit if its sustainability is maintained because it can absorb carbon which gives a great economic value. Efforts to manage and preserve Eden Forest Park 100 as a tourist attraction have been carried out in an integrated manner with the government, private sector and local communities, but need to be increased so that forests can provide environmental services in a sustainable manner.
