Abstract:

The use of unclean water is one of the causes of skin diseases. Skin diseases are often suffered by students in the Islamic boarding school environment because sanitation facilities may be inadequate. It is known that the water source in the Islamic boarding school uses drilled well water. The purpose of this study was to determine the quality of clean water in the male dormitory of the Abu Hurairah Mataram Islamic boarding school, which was reviewed biologically. This type of research is descriptive qualitative. The population in this study were all the water taps in the male dormitory of the

In recent years, refillable drinking water businesses have grown rapidly in several cities in Indonesia, including Ambon City. On the one hand, Refillable Drinking Water Depots (DAMIU) support efforts to realize a healthy society by expanding the reach of clean water consumption, On the other hand, DAMIU tend to be problematic when faced with business interests. Feces contain coliform bacteria which is an indicator of water contamination. This study aims to determine the presence of coliform bacteria in Ambon City.
