Volunteers Perception and Motivation on Implementation of Community Empowerment National Program-Autonomous Urban

Indonesia is a developing country which has focused on development. The development and acceleration of economic growth that occurred in Indonesia has not been evenly distributed in every province. This gives rise to a phenomenon of population movement (migration) occurring in rural communities who migrate to urban areas which eventually give rise to a phenomenon of urban poverty. The purpose of this study was to identify the characteristics of poor communities urban areas and to identify social representations about the city in poor communities in urban areas. The characteristics of poor communities are generally aged between under 25 to more than 54 years old, the majority of respondents are women, and generally work in the informal sector. The level of education of respondents are elementary school level (SD) or equivalent to high school level (high school) or equivalent. The income that can be obtained by poor communities were Rp. 100.000.00 up to Rp.1.500.000.00 per month. Overall poor communities did rural-urban migration between 1970 until 2010. The reason was to find a job, looking for experience, come to join her parents and husband, and generally they spent a time in a location was between 1 to 30 years. The frequency of returning home is zero to more than 4 times in the past year. Most of them do not choose the location as the first residence in the city. There are 4 kinds of type of social representations about the city and the poor. The dominant type of social representations about city is type a place to earn money. Beside that, the dominant type of social representations about the poor is underprivileged person

ENERGY MINIMIZATION FOR IDENTIFICATION OF BANDING PATTERN IN CHROMOSOMES USING OPTIMIZED GRAPH CUT ALGORITHM

Intensity inhomogeneity is a significant cause in reducing the accuracy of image segmentation. This paper proposes an algorithm for identification of bands in chromosomes using graph cut segmentation that uses global and local image statistics. The global energy is an estimate of the intensity distribution of the image and background and local energy provide the information related with neighboring pixels that eliminates the impact of intensity inhomogeneities. Efficient energy minimization helps in better pixel labeling and this is done by optimized Graph cut process. The shape prior of the band at each location of the image is considered with shape probability energy functions. The experimental results demonstrate that the approach is robust and efficient in detecting the band information in chromosomes to a larger extent
