Abstract

As a result of the growing population of Indonesia from year to year will affect the security of national food stocks. Demand for various types of foodstuffs will continue to increase, including beef. The growth of beef consumption per capita of Indonesian society tends to increase. During the last five years (2013-2017) the national beef cattle population shows positive growth, continuing to increase by an average of 1.54% per year. The growth of large-scale cattle farms has an impact on increasing the amount of livestock waste. The challenge of developing livestock sub-sector is to increase meat production and reduce the risk to the environment. Various kinds of waste management can be applied to livestock business before being released into the environment. Conventional end-of-pipe treatment strategies are being shifted to more profitable strategies. The processing of cattle dung manure into organic fertilizer through composting technology becomes one of the favorable alternatives. Composting is an effective method of recycling abundant livestock wastes into products that are stable, sterile, and agriculturally useful. Some technological advances in composting are essential to be applied in compensating for the production rate of cattle manure.
