Backgrounds: Direct observation of people who live above the sea, there are people who do not use soap when cleaning themselves because they bathe directly in the sea and they throw their garbage at sea. This is because people's knowledge is still lacking regarding their actions in throwing garbage at sea so that it makes the sea polluted where sea water is used for personal hygiene including washing and there are 70% of people using septic tanks openly that go directly to the sea. This attracts researchers to conduct research on the analysis of the effect of focus group discussion on the level of knowledge and attitudes of the Bajo Community in the Wawonii Health Center Working Area.
