Abstract

Carbon-monoxide, chloro-fluorocarbon, nitrogen-oxides, carbondioxide, sulfur-oxides, hidrocarbons, particulate matters and others are known as potential air pollutants. These compounds can be released by automobiles, electric power' generators, industries, household, agricultural burningsand forest fires. Air pollutants can be harmful to human beings directly or indirectly. They may cause melanoma (skin cancer), alopecia, angina pectoris, bronchitis, emphysema, asphyxia etc., and they can also disturb buildings, agricultural crops, forest vegetation, wildlife, water, soil, climate, and other natural resources.

Abstract

Land clearing as one of major activity in geothermal exploration and humans activity cause more deforestation in Kamojang Nature Reserve and disturb the role of forest as a storage of environmental services. The aim of this research is: 1) to measure the land cover change and determine the forest status of Kamojang nature reserve and 2) to identify socio-economic factors that cause deforestation.  Analysis report from citra landsat showed us the type of land cover was dominated by forest for about 4231.26 ha with forest cover presentage around 51.17%. By that result, Kamojang nature reserve has been called as a disturbed status. In the other case, sosio-economic factors that cause deforestation were totally significant for salary and status of land tenure. Both of these factors significantly influence deforestation in the Kamojang Nature Reserve at 5% level of significance. The significance of one variable would have an effect to the forest deforestation. Those results of research reflected a part of effort in managing Kamojang Nature Reserve and geothermal environmental services. Keywords: Deforestation, Geothermal, Land cover, Socio-economic, Kamojang Nature Reserve

Abstract

Lubuk Paraku sub watershed is located at Batang Arau up-stream with Lubuk Paraku river as the main river. It is an area dominated by protected forest and conservation forest, such as Tahura Dr. Mohammad Hatta. Bukit Barisan I Lubuk Paraku water resource has a good quality and quantity, also fulfilled the environmental quality standards. Lubuk Paraku river is at good category for sustainability resource, it is shown by the coefficient of river regime value. Land cover distribution at Lubuk Paraku sub watershed highly dominated by secondary forest, covering an area of 1.520,15 ha or 61,27%. Lubuk Paraku River has numerous water debits; therefore it has a massive utilization potential for various needs such as household utilization, agriculture, power plants and industrial. Total economic value of water resource in Lubuk Paraku sub watershed is 57.122.973.850,-/year.    Keyword:, Hydrology, Lubuk Paraku watershed, Massive utilization, Secondary forest, Total economic value.

Abstract

Air temperature in cities are increasing which can cause reduce the human comfort and productivity. Urban forest can make the environment comfortable. The objectiveof the researc hwere: (1). To Determine the effects of urban forest on air temperature and relative humidity, (2). To analyze the effects of physical characters of trees ont he micro-climate amelioration and(3). To Determine species of trees which are very effective for micro-climate amelioration.The results of the research revealed that the average of daily air temperature in the urban forest was 30.2 C with arelative humidityof 74.0%, while the daily air temperature around the urban forest was 31.8 Karakter Fisik Pohon ... (Dahlan E) o C with relative humidityof 71.1%. Tree composisitin of all study sites consist of192trees, 29 speciesand 13families. The TinjomoyoForest Tourism has the highest density of trees(406trees/ha), while the lowest in the Parks Minister Supeno (316trees/ha). Value of Key Performance Indicator (KPI) of trees based on calculation of tall of trees, diameter of canopies, total leaves area and canopy forms noticed that very effective trees for micro-climate amelioration were: Angsana(Pterocarpus indicus), beringin(Ficus benjamina), flamboyan(Delonix regia) , ketapang(Terminalia catappa), mahoni (Swietenia mahogany), andtrembesi (Albizia saman).
