Abstract

Bamboo (Bambusa sp) is a forest plant that has many benefits but is not yet used by forest communities widely. This study aims to determine patterns of distribution, economic value and contribution of Bamboo.  This research was using purposive sampling technique. Based on research conducted bamboo evenly to the patterns of distribution and the dominant grows at an altitude of  700-1100 mdpl, while the highest economic value of bamboo is Rp. 9.450.000/year and the lowest economic value is Rp. 810.000/year, while the highest contribution of Bamboo to people’s income is 33,40% and the lowest contribution of Bamboo is 4,84%   Keywords: Bamboo, Distribution Pattern, economic value, contribution, income

Abstract

Daun Sang is an plant endemic of Sumatera. This plant only found in two places in Indonesia in Bukit Tigapuluh National Park and Gunung Leuser National Park. This research is important to rescue Daun Sang. Based on spatial analysis can provide important and accurate information about the habitat linkages of Daun Sang. Daun Sang of the components of a particular habitat, areas that may be used as habitat for Daun Sang, or they can be for the predict Daun Sang population in an area and view information about the condition of habitat at any given time. This study aims to map the distribution of Daun Sang and predict the level of habitat suitability based on altitude. Belt Transect used  for this research and overlap (overlay) to create a map of the distribution of Daun Sang. The results showed that Daun Sang were found scattered near each other between one individual with another individual on sloping land and grow in the shade of the trees. Daun Sang habitat suitability for altitude in the resort level Sei Betung is ≥ 60 masl and high suitability for level terrain is "very steep" (≥ 45%). Keywords: Daun Sang (Johannesteijsmannia altifrons), Spatial Analysis, Resort Sei Betung.

Abstract

Forest act as a habitat which is one of the main elemen in orangutan lives. Increasing rate of forest degradation in recent years considerable influence on the orangutan population growth, its looks from the orangutan population decline significantly in recent years. Therefore, it is necessary to the preservation of orangutans through habitat management, and ecological and quantitative aspect of orangutan become interest of this study. The methodology which used in this research are the direct observation of daily activities orangutan’s and vegetation analysis in the forest spots that have been passed by the orangutan. The result of this research shows that orangutan average active starting at 07.33 WIB and start to make a nest for sleep approximately at 18.15 WIB with an average length of daily activity orangutan approximately 10 hours 42 minutes. Daily activity averange of orangutan for proportion duration are 15,03% for feeding, 36,59% for moving, 44,82 % for resting, and 3,56% for nesting and for frequencies are 24,09% for feeding, 32,95% for moving, 37,76% for resting, and 5,2%% for nesting. The composition of forest vegetation consists of 24 species of trees, 15 species of poles, and 20 species of saplings which identified overall approximately 88,53% of food plants. PPOS forest area has an index of species diversity (Sannon Wiener index) 2.717 species of trees, 2,235 species of poles, and 2,554 species of saplings.

Abstract

Information on the potential of forest stands is necessary to know the state and the amount of natural resources contained therein. Potential stands a forest area estimates can be obtained by various methods. This study aims to estimate and compare the potential stands between sample units and determine the most efficient unit instance performed in forest crop production. This study uses systematic random sampling with a sample on circular plots and tree sampling. Circular plots used area of ​​0,05 ha (12,62 m diameter) and tree sampling using 6, 8 and 10 trees in the sample. The results showed the best efficiency levels obtained 6 trees sampling, and accuracy approaching sample of circular plots. Circular plots had the lowest sampling error. Sampling error is less than 5%, so the circular plots had the highest accuracy compared to other sample units. Thus, the circular plots is a sample of the recommended applied to the public plant forest. Keywords: Potential stands, Samples, sampling error, efficiency

Abstract

Land use and land cover is an important component in understanding the interaction of human activities with the environment. Forest management include the planning and supervision in the Karo regency forest becomes very important to do in order to prevent degradation of the forest more severe. The purpose of this study was to quantify changes in land use from 1997 to 2012 and makes predictions extensive land use in 2018 and 2024. This research methods  to utilize remote sensing technology and geographic information systems (GIS) and then compare the 5 maps of land use interpretation of Landsat ETM + (1997, 2000, 2003, 2006 and 2009 ). Classification results show that the Karo Regency has 11 land cover classes. The equation obtained from the linear regressions used to predict land cover area.The results showed that widespread changes in land cover occurred in dryland farming into rice paddies. Therefore, it is necessary that proper spatial planning in Karo Regency. Key word : land use change, land cover, landsat ETM+ image

Abstract

City is the center of government and human activities. The tendency of all activities centered in the city results increasing of city development. This impacts the reduction of Green Open Space especially the urban forest, the increasing of carbondioxide concentration and the reduction of oxygen in the air. Such condition can reduce the urban environment quality, because one of the functions of urban forest is to absorb carbondioxide. This study aims to analyze the needs of urban forest width based on the function of carbondioxide absorber in Medan up to 2050. The method used was by collecting primary and secondary datas, then data analysis was performed to determine the optimal width for urban forest. The results showed that in 2012 Medan city need urban forest width for carbondioxide absorber about 4.304,21 ha and in 2050 is 9.880,06 ha.
