ANALISIS SWOT STRATEGI PEMBERDAYAAN MASYARAKAT PROGRAM PENATAAN LINGKUNGAN PERMUKIMAN KOMUNITAS DI KELURAHAN SURYATMAJAN, KOTA YOGYAKARTA

Community empowerment has wide meaning from various point of view. Community empowerment is the emphasis on the behavior of self-sustaining local communities as a system that breaks down themselves. Communities have the right to determine strategies for empowerment strategies according to their strengths, weaknesses, opportunities, and threats. Analysis of empowerment strategies through SWOT analysis for strategies that can be in accordance with the characteristics of society. This research was conducted at the priority location of Community Based Settlement Environment (PLPBK) program of Kelurahan Suryatmajan with number of informant 30 people and sampling technique using snowball sampling to find an information. From the analysis result, based on aformentioned reasons there are 4 segments of community empowerment point in the priority areas, namely handicraft and food industry, eco-green area, green open space area, and river arrangement. The determination of community empowerment strategy is the initial stage of overall empowerment activities, because the initial stage can determine the category of society and the pattern of empowerment to be undertaken

The Impact of Green Open Space on Community Attachment—A Case Study of Three Communities in Beijing

With the development of urbanization in China, the quality of urban life and community attachment have attracted increasing attention of the governments and society. Existing research on community attachment has mainly examined how individual characteristics affect community attachment, such as their length of residence and socioeconomic status. However, some scholars have become interested in exploring the effects of green open space on community attachment. This research examined whether the distribution of green open space in communities had significant effects on community attachment, and both the impact and path were also investigated. Through a questionnaire survey, relevant data in three communities of Beijing were collected. The impact of green open space layout on community attachment was evaluated by using hierarchical regression, and the impact path was examined by using a structural equation model. The results showed that green open space in a community had significant effects on the community attachment, with centralized green open space layout having a greater effect than that of dispersed green open space. Moreover, the more complex the shape of green open space is, the greater the impact is. The degree of satisfaction with the green open space had direct effects on the community attachment. The accessibility and perceived area of green open space could indirectly have an impact on the community attachment by affecting the degree of satisfaction with the green open space. Nevertheless, residents’ perceived importance of green open space could affect the community attachment directly and indirectly, as it affects the degree of satisfaction.

Manfaat Kanopi Pohon dalam Mereduksi Aliran Permukaan Studi Kasus: Sempadan Sungai Ciliwung Tengah, Kota Bogor

ABSTRACTThe Benefit of Trees Canopy in Reducing RunoffCase Study: Border of Center Ciliwung River, Bogor MunicipalityBogor as one of Center Ciliwung Sub Region River flow has decreased the percentage of green open space from year to year (Bappeda 2007). Study area boundary is the border as far as 300 meters to the left and right side of Ciliwung River. The method of this research is to estimating the benefits of tree canopy using Quickbird satellite image of the city of Bogor in 2006 with the software ArcView GIS 3.2 extensions CITYgreen 5.4. The study includes comparisons between the percentage of built up area and green open space. Comparison of built up area and the largest area of green open space can be found in Tanah Sareal District, the ratio reached 2:1. While the smallest ratio can be found in the MiddleDistrict of Bogor (1:1). This means the ideal condition of river’s border are found in the Middle District of Bogor that can decreasing runoff well. The estimation of trees canopy benefits can be seen from the amount of runoff volume, it can be predicted that trees canopy in study area can reduce average ± 7,55% of runoff volume. This means that the conditions in the study area was still below the average standard riverine.

APLIKASI TEKNOLOGI PENGINDERAAN JARAK JAUH UNTUK MENGIDENTIFIKASI HEAT ISLAND (“PULAU PANAS”) DI KOTA PEKANBARU

The increasingly development in Pekanbaru city caused the environmental change. This condition also affected to the increased of surface temperature on the urban area of Pekanbaru City. The increasing of surface temperature will lead the increasing of air temperature which could impact to the uncomfortable activity in Pekanbaru City. The high air temperature in urban areas is caused by increasing built-up areas and declining green open space. Green open space should be built to lower air temperature and to create a comfortable micro climate. Green open space should be developed at locations with high air temperature to reach its efficiency. The research was aimed to identify the phenomena of Heat Island in Kota Pekanbaru. The processing satellite image data of band 6 of Landat 7 ETM+ was conducted to produce the distribution of surface temperature in Pekanbaru City. The results shows that, the surface temperature of the urban area is higher than the green open space area, especially for residence area, road, office building area and bare land. This condition indicates that the phenomena of Heat Island accurs in Pekanbaru City.

Mainstreaming Adaptation Climate Change into Strategic Environmental Assesment Case Study Banyuasin District, South Sumatra Province

South Sumatra Province is one of the areas in Indonesia which tipped to be prone to the impact of climate change and very vulnerable due to its low-land areas that it may threat coastal, water, agriculture, and health sectors of the province. In Banyuasin District, the current program has been planned deep sea port development in ??Tanjung Api-api area. Coastal flood hazard components caused by a combination of sea level rise, storms, and La-Nina phenomena on maximum tide. In this study measured tidal hazards due to sea level rise. Risk area generated by layering hazard and vulnerability maps using GIS methods. The results of the risk assessment shows increase risk in the water availability at high risk level with percentage area ??38.87% and 46.02% at baseline conditions and projections. Adaptation efforts conducted to overcome the conditions mentioned above is by controlling the arrangement, the addition of retention ponds as a water storage and flood prevention efforts and also maintaining an area of green open space area above 30%. One of the priorities recommended program is a program of development and the development of sanitation where mitigation / adaptation recommended by increasing the efficiency of use of raw water, saving water resource utilization, and environmental sanitation. The results of this study need to be integrated / mainstreamed into development policies and plans regional / local so helpful to the development of a better way to identify the agenda on national plans, provincial and local levels are associated with adaptation to climate change.

KAJIAN DAYA DUKUNG SUMBER AIR HUJAN TERHADAP RENCANA TATA RUANG WILAYAH (RTRW) KOTA DEPOK

ABSTRACT 
 A city development is indicated by population growth and more complete facilities compare to rural area. Depok is one of city with massive development nowadays with high economic potential. In 2010, depok population is 1.675.213 peoples, this number has increase by 31.65% compare to 2000 (1.145.091 peoples), the average population growth is 3.64% per year.
 In line with high population growth and changing on people dynamic, most of green open space area (rth) has shifting the function into used spaced with many buildings is develop nowadays for residential (house, apartment), office building, restaurant, etc.
 For supporting population growth, one of the most important factor need to consider is the availability of reserved water for supporting people’s daily life.
 The main objective of this study was to determine the potential capacity of rain water sources to the spatial plan of depok city in 2010. Some of water source for covering all depok area are kali, situ & ground water. Currently, the usage of ground water is more dominant (used by 82.5% of total population). 
 Based on the research result, potential source of rain water in depok is sufficient because the annual rainfall duration is very high (1106 – 4579 mm), resulting on the surplus value of dependable flow in each districts, except in beji district during dry season, in september and oktober.

Soil Erodibility of Several Types of Green Open Space Areas in Yogyakarta City, Indonesia

The city development tends to reduce green open space area. This land use change will affect the soil erodibility and then increase the erosion rates. Therefore, the existence of green open space area is very important in preventing soil erosion of the city. In Yogyakarta city, there are several types of green open space area, but there is still lack of data on how far those areas play role in erosion process. The objectives of this research were: a) to measure the value of soil erodibility of several types of green open space areas, and b) to study the soil characteristics related to soil erodibility.The soil erodibility measurement was done at the 11 sites samples of green open space area of Yogyakarta city, including river side, sport field (3 sites), garden (2 sites), office yard, settlement, school yard, and zoo (2 sites). In this research, both disturbed and undisturbed soil samples were taken from the field then analyzed in the laboratory. The K formula of Wischmeier and Smith was used for calculating the soil erodibility.The research results showed that the soil texture was mostly sandy loam; the soil permeability ranged from the lowest of 2.34cm/hr (at the grass of the zoo) up to the highest of 34.88cm/hr (at the city garden). The soil organic matter ranged from the lowest of 1.2% (at the school yard) up to the highest of 5.65% (at the office yard). The soil structure could be classified as granular at all areas. In general, the green open space area had soil erodibility of 0.16 to 0.29 which was considered as low level. It means that the green open space area reduces soil erodibility. Based on this result, it is strongly recommended that in developing the city, the area of green open space must be allocated.

都市内緑地における有機性廃棄物の還元可能性に関する考察

We have a lot of organic waste, especially in urban area. Urban cities should manage to treat its organic waste within the cities as much as possible. In order to run composting system of organic waste successfully, we need more green open space where recycled compost can return to the soil. Composting also improves the urban soil, and the improved soil can grow rich and healthy green. This will also be effective in controlling heat-island phenomenon and floods in urban areas. However, there are some risk affecting our environment and health in recycled compost. Therefore, we should structure the recycling system after careful consideration, i.e. we should consider the correspondence between organic waste's risk and space's property. From this point of view, urban green open space can be ranked as Green Open Space for Return, in which recycled compost can return to the soil, more safety. In this study, we try to grasp the area of Green Open Space for Return in Musashino-city, Tokyo, from the data of green covered space. In addition, we examine the possibility and subject for securing necessary space. And consequently, we show that in some chou-chou-moku area, it is possible to return recycled compost, which the population dumped, to the soil by counting not only the public green open space but also private gardens.
