Unfortunately, field studies from Central Java show that the people of Semarang use the river as a toilet. This habit has been done over the decades and endangers the health of residents and the environment.

With our project, we want to present a model of sanitary facilities and construct it in Tambak Lorok (Semarang). In this project, wastewater and waste treatment system are to be integrated. Applications are being made to convert the faeces into the end products of fertilizers and biogas. We are convinced that people need a realised model to adopt this technology and change their thinking about waste disposal. Furthermore, the residents’ knowledge 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 locally by the residents’ local, guided by LPUBTN and BUGI, to promote society’s development by improving the financial situation, in addition to hygiene and environmental protection.
