There are more than 20,000 dairy cows in Lembang that can produce more than 200 tons of manure. Most traditional cow farmers do not process the cow dung and just throw it on the river. Established in 2013, CV Energi Persada is a social enterprise aimed at improving cow farmers’ income in Lembang, West Java by producing and selling biogas reactors. These biogas reactors are made from biomass waste, which usually are not fully utilized by people. Then the reactors are used as household cooking fuel and reducing household expenses of the farmers’ family as well. The business also aims to increase the awareness of environmental issues in Indonesia and the modification of human behavior towards these issues.
