The objectives of the programs areapproach the society by socializing about the benefits of water hyacinth convert to biogas and liquid fertilizer, to trainskilled of people to build a biogas unit. The result of this programs makes a biogas unit MERCEDES (Mesophilic ReactorAnaerobic Digestion) which produces biogas and liquid fertilizer. The economic potential is obtained if all householdsapply them (equivalent with energy) about IDR 17.112 million per year, a liquid fertilizer about IDR 200.000 perhousehold per day, the environmental potential reduction of water hyacinth growth about 6-15% per year, providingknowledge to the community to build a biogas unit and Mr. Musyafa has been utilize the biogas and fertilizer and haveformed the structure of the organization to manage and develop the biogas unit for sustainability the program.
