One waste produced from cattle farms is cow dung (in solid and liquid form). In practice this cow dung is usually discharged directly into the river and causing river pollution. The case that occurred was the upstream flow of the Citarum watershed river pollution due to cow dung was a problem for residents around the river. The use of cow dung that can be done is the manufacture of biogas and liquid fertilizer using cow dung so that the cattle-friendly cattle system is created. In addition to the cost of costs, there are obstacles in the form of a lack of insight into biogas and its benefits as well as renewable energy sources and benefits to improve the quality of the surrounding environment. The previous community had already had biogas installations but did not understand the details of the processes and types and care of biogas to better understand how good use of biogas, is therefore needed a mentoring program for cattle farmers to increase the use of cow dung into biogas and liquid fertilizer. This activity conducted a field survey to see existing biogas conditions, the manufacture of biogas installations, installation of biogas installations, workshops and training of cow dung processing into biogas and liquid fertilizer. In addition, training on how to make liquid fertilizer from materials that are easily obtained such as brown sugar, shallots, coconut water, coffee and others other. The enthusiastic community participated in this activity, with the presence of briefing on processing of cow dung, especially biogas society seeking to improve biogas installations.

The damage that occurs in biogas installations belonging to citizens is generally quite severe as it has been buried, a landslide installation place, so it requires large enough funds to fix it. The cost of making a biogas installation measuring 3 cubices reaches 6-8 million rupiah, so the funds needed are large enough if they have to provide assistance to individuals.
