Abstract

The increase of developmental success in urban areas has caused a rapid increase of urban population. The growth of urban population also causes various problems of environmental pollution due to their daily activities. Bali which is internationally famous for its tourist resort, continuously strives to complete facilities and infrastructure, both in maintenance as well as tourist resort conservation, and one of the efforts is by integrated urban waste management to create a clean and healthy Bali and to develop tourism with an environmental insight.

EM Technology is one of the organic fermentation technologies which was found by the second author in 1980, and is applied to process urban organic waste. This research is a model of integrated organic urban waste recycling with EM Technology, which may be applied in a smaller scale all over the cities in Indonesia as well as other countries. The benefit of integrated organic waste management are:

Save costs for final disposal as more than 50 per cent of all organic waste is reprocessed and utilized for the purpose of agriculture and animal husbandry on a wider scale.
No environmental pollution, thus water, air and soil pollution may be reduced. Urban people may be healthier and more dynamic as they live in a healthy environment.
Provide source of income, employment opportunity for organic fertilizer and animal breeding industries - providing organic fertilizer and cattle feed at cheap cost.
Increase tourist visits, as the city is clean, tidy and friendly to the environment. Tourists also tend to see how to manage urban organic waste.
Provide education, research and developmental facilities for integrated urban waste management with EM Technology.

The recycle system of integrated organic urban waste is divided into 10 units of integrated works, which can be developed into a big scale as : separation of organic and inorganic waste; distribution of organic waste as cattle feed; fermentation organic fertilizer production unit; unit of cow and goat breeding; worm breeding unit; plant seedling unit; mushrooms plantation unit; research and development unit, training and education; tourism unit and marketing unit of organic / inorganic products.

This research is also completed with economical analysis of various units of works in integrated organic waste management with EM Technology. The result of this research is very exciting to be applied in big cities in Indonesia because of its various benefits. In a short time, this recycle system of integrated organic waste management with EM Technology will be applied in Bali on a bigger scale as a model for other cities in Indonesia and other countries.
