According to our field studies from Central Java at the beginning of 2017 numerous residents of Semarang, unfortunately, use the river, mangrove plantation, and other public spaces close to the water as toilets. This habit has been established over the decades and endangers the health of residents and the environment.

Through our project, we want to present a model of sanitary facilities and build them in Tambak Lorok (Semarang). A wastewater and waste treatment system are to be integrated. As an addition, efforts are being made to convert the faeces into the end products of fertilizers and biogas. We are convinced that people need a visual model to adopt this technology and change their thinking about waste disposal. Also, the residents’ knowledge of the topics of health and hygiene is to be strengthened. The people in our target group should understand the technology behind the sanitary facility to operate and maintain the facility properly. 
The end products are managed on-site by the residents involved, accompanied by LPUBTN and BUGI, to promote the development of society by improving the financial situation, in addition to hygiene and environmental protection.
