Student conception about the quality of packaged water

Instead of a pure state, water on earth contains a variety of material, either dissolved or suspended, including microbes. Therefore, before being consumed, water should be processed first to reduce levels of contaminants to a save level. Standard of water quality for household need (Permen No.492/MENKES/PER/IV/2010) is usually used as a reference for drinking water requirement. This preliminary study was carried out to investigate students' conception of packaged/bottled water quality assurance produced by certain vocational schools as products of their students. The explanatory survey method was used in this study to detect their conception deeply. The respondents or participants of this study was ten graders from a public vocational school in Subang and their teachers in Agribusiness course. Data were collected through observation, interview, and test for their preconception. Research results show that students' knowledge about mineral water is not in line with their understanding of the water quality, and their teacher's as well.
