Various research indicates that most land-intensive agriculture has been declining productivity and land degradation, primarily associated with very low content of organic carbon in the soil, which is 2% . In fact, to obtain optimum productivity of organic carbon required at least 2, 5% . Organic fertilizers are very useful for the improvement of agricultural production both in quality and quantity, reduce environmental pollution, and improve the quality of land in a sustainable manner. The use of organic fertilizer in the long term can increase land productivity and to prevent land degradation.

Organic fertilizers increasingly popular and widely used, this is caused by the increasing difficulty of getting an inorganic fertilizers and the findings that the use of an organic fertilizer ( Chemistry) in the long run without the use of organic fertilizer Balance can cause damage to physical and chemical properties of soil including the destruction of living microorganisms in soil. The use of organic fertilizer ( compost) quality is in need to improve the conditions mentioned above. Quality organic fertilizer procurement efforts with simple technology and low cost absolute need for the process of production of farmers.

Efforts to support the improvement of quality organic fertilizer taken by the provision of machine tool for preparing organic fertilizer so that farmers attract users. Next, the existence of technologies and sources of raw materials cheap and affordable ( affordable) for the mixing of enrichment ( enrichment) of nutrients. In the presence of machine tool technology, compost - as the largest raw material ( derived from organic waste in urban areas) - are available for the development of organic agriculture, can be served more practical, efficient and relatively cheap in the eyes of farmers.
