This condition was really suitable because they live in the mountain slope. However, they had not utilized their cow manure waste. They disposed cow manure around their stall. Consequently, less good smell resulted. This condition made Widodo aware of beginning to construct digester and biogas reactor to utilize the cow manure waste. According to Widodo, if this manure problem was not coped with, it would have resulted in disease. Widodo’s attempt, in fact, yielded positive result. Cow manure waste could be converted into biogas that could be used as energy source. In addition, cow manure waste that had been degassed could be used as organic fertilizer with quality equal to the chemical fertilizer’s quality. Moreover, the always-cleaned cow stall could produce quality cow milk. This Widodo’s success could open Balong Wetan people’s insight. Balong Wetan people gradually began to imitate constructing digester and biogas reactor surrounding their house. This digester and biogas reactor construction was helped by local government recalling that Balong Wetan people were largely at low economic level. Conclusion: Cow manure waste utilized as energy source affected positively the people’s economy. People could produce their own biogas that could be used as fuel in their household and could produce organic production from cow manure waste. Thus, people no longer needed to buy fuel or fertilizer, so that the money usually spent on those needs could be saved or spent on other needs. Another economic effect was that people could sell cow milk at higher price because the quality was better due to the daily cleaned stall. In addition, the people’s creativity emerged to open business by processing the cow manure waste.
