This has transformed the island into a province that enjoys good economy thus achieves relatively good living standard for most of its population. However, some villages in Bali are still without access to electricity due to reasons associated with topography of the villages in which they are mostly located in high mountainous area or deep in the valleys. Such topographical characteristic has hindered the expansion of utility’s grid due to high initial cost and less attractive energy sales in the village. Meanwhile, world has recognized that electricity is a necessary support for achieving many of the millennium development goals that set to improve the quality of human life. Moreover, our constitutional mandates stipulate that earth, water and any resources thereof should be utilized to benefit our citizen irrespective of geographical and topographical condition of their location. The research reported here is the result of investigation on the current status of un-electrified sub-villages around Bali. Based on our research, the amount of power required to electrify those areas is less than two megawatt. Solutions to provide electricity to the affected area are discussed. Discussion includes the availability of local resources such as natural, social and human resources available in those areas in view of developing locally managed energy plants. Renewable generation technology such as solar photovoltaic, microhydro and wind turbine is discussed in order to provide a green and sustainable electrical energy supply for basic use in the affected area around Bali.

One type of vegetable which can be cultivated using hydroponic is green mustard (Brassica juncea L.) tosakan variety. This vegetable is harvested in the vegetative phase, approximately aged of 30 days after planting. In addition, during the vegetative phase, this plant requires more nitrogen for growth of vegetative organs. The lack of nitrogen will lead to slow growth and the leaves turn yellow. In this study, non-destructive technology was developed to identify nitrogen status through the image of green mustard leaf by using digital image processing and artificial neural network. The image processing method used was the color moment for color feature extraction, gray level co-occurrence matrix (GLCM) for texture feature extraction and back propagation neural network to identify nitrogen status from the image of leaf. The input image data resulted from acquisition process was RGB color image which was converted to HSV. Prior to the color and texture feature extraction and texture, acquisition image was segmented and cropped to get the leaf image only. Next Step was to conduct training using back propagation neural network with two hidden layer combinations, 20,000 iteration epoch. Accuracy of the test results using those methods was 97.82%. The result indicates those three methods is reliable to identify nitrogen status in the leaf of green mustard.
